I would like to style a `<ul>` to display all items in a box with rounded corners (see below):  Is it possible to use CSS and only the `<ul>` (with no additional `<div>`s and tables), as I'm going to use it in a CMS system to style all `<ul>`s created by the user?

In a Silverlight interface I'm working on I have the need to resize a stack panel when its container resizes, to prevent the text in it from being truncated. The text in question is added at runtime from language files, depending on the language the user has selected. As the lengths of strings can vary considerably between languages I'm a bit stumped on how best to approach this. This is what it looks like.  The stack panel in question is the coloured block and the labels Driving, Active Work, Availability and Break are the strings whose length can change. The XAML currently looks like this. ``` <StackPanel x:Name="StatusTotals" Grid.Row="1" Orientation="Horizontal" VerticalAlignment="Center" HorizontalAlignment="Center" Margin="0,5,0,5"> <Border x:Name="DrivingBorder" Background="#80FF0000" BorderBrush="Black" BorderThickness="1" Opacity="1" CornerRadius="5,0,0,5" Margin="0,0,-1,0"> <StackPanel Orientation="Vertical" Margin="5,1" VerticalAlignment="Center"> <TextBlock Text="Driving" Tag="dttlDriving" HorizontalAlignment="Center"/> <TextBlock x:Name="DrivingDuration" Text="00:00" HorizontalAlignment="Center"/> </StackPanel> </Border> <Border x:Name="ActiveWorkBorder" Background="#8000FFFF" BorderBrush="Black" BorderThickness="1" Opacity="1" Margin="0,0,-1,0"> <StackPanel Orientation="Vertical" Margin="5,1" VerticalAlignment="Center"> <TextBlock Text="ActiveWork" Tag="dttlActiveWork" HorizontalAlignment="Center"/> <TextBlock x:Name="ActiveWorkDuration" Text="00:00" HorizontalAlignment="Center"/> </StackPanel> </Border> <Border x:Name="AvailabilityBorder" Background="#80FFFF00" BorderBrush="Black" BorderThickness="1" Opacity="1" Margin="0,0,-1,0"> <StackPanel Orientation="Vertical" Margin="5,1" VerticalAlignment="Center"> <TextBlock Text="Availability" Tag="dttlAvailability" HorizontalAlignment="Center"/> <TextBlock x:Name="AvailabilityDuration" Text="00:00" HorizontalAlignment="Center"/> </StackPanel> </Border> <Border x:Name="BreakBorder" Background="#8000FF00" BorderBrush="Black" BorderThickness="1" Opacity="1" CornerRadius="0,5,5,0"> <StackPanel Orientation="Vertical" Margin="5,1" VerticalAlignment="Center"> <TextBlock Text="Break" Tag="dttlBreak" HorizontalAlignment="Center"/> <TextBlock x:Name="BreakDuration" Text="00:00" HorizontalAlignment="Center"/> </StackPanel> </Border> </StackPanel> ``` I would like to be able to reduce the size of this panel if it's wider than the ruler drawn above it, which is already dynamically resizing as I want, but would like the values beneath the labels to stay at the size they are for the sake of readability. What would be the best way to approach this? I've considered setting the FontSize properties of the labels or using a ScaleTransform but I'm unsure which of these is the best way to go. Is there a way to derive the width that the panel will adopt without actually changing the font sizes and then testing ActualWidth? If I could do this it would make this task easier.

How would I "inflate" a polygon? That is, I want to do something similar to this:  The requirement is that the new (inflated) polygon's edges/points are all at the same constant distance from the old (original) polygon's (on the example picture they are not, since then it would have to use arcs for inflated vertices, but let's forget about that for now ;) ). The mathematical term for what I'm looking for is actually . +1 to balint for pointing this out. The alternative naming is .

I have three images that I would like to join in a widget I'm creating in Html. I just want to give the round effect on the corners. These are the three images:    I have the middle one repeating in my css so that it fills up the space between the two edges. ``` .widgetMainLeft { background: url('/Content/Images/Title_Bar_Left.png') no-repeat; width:6px; min-height:100%; } .widgetMain { background: url('/Content/Images/Title_Bar_Middle.png') repeat-x; text-align:left; margin-top:auto; min-height:100%; } .widgetMainRight { background: url('/Content/Images/Title_Bar_Right.png') no-repeat; width:6px; min-height:100%; } ``` I am placing these three classes in one container class, but it simply displays the middle one. The background images are at the top of the widget where the title is. ``` <div class="widgetBody"> <div class="widgetMainLeft" /> <div class="widgetMain"> <div class="widgetTitle">Messages</div> <div class="widgetDisplayedArea"> <table> ... </table> </div> </div> <div class="widgetMainRight" /> </div> ``` This is how the widget looks now:  And this is how it should look:  How can I make this effect happen?

How can I join background images?

I want to "fix" the Background while only the ListFields scrolls. Current Problem:  Scrolling Down (the surounding box should move with the List)  Corresponding code for the VerticalFieldManager ``` VerticalFieldManager _bottom_box = new VerticalFieldManager(Field.FIELD_HCENTER | Field.FIELD_VCENTER | VerticalFieldManager.VERTICAL_SCROLL | Field.USE_ALL_HEIGHT) { protected void sublayout(int maxWidth, int maxHeight) { super.sublayout(maxWidth, maxHeight); setExtent(maxWidth - 6, maxHeight - 3); } protected void paint(Graphics graphics) { graphics.clear(); graphics.setColor(Color.WHITE); graphics.fillRect(0, 0, (this.getWidth()), (this.getHeight())); graphics.setColor(color_computacenter_light_blue); graphics.drawRect(0, 0, (this.getWidth()), (this.getHeight())); super.paint(graphics); } }; ``` Any Ideas, how to fix this? Thanks

I'm building app that will store large video files to the server and then user will be able to view them. For my app I'm using GWT + GAE/J and to store files I would like to use S3 account. But as we know that you can upload max 10mb to GAE. I have [asked this kind of question](https://stackoverflow.com/questions/1067596/gwt-on-gae-and-s3) before and the answer that I have accepted will work only if you have file less then 10mb. That [solution](http://bizo-dev.blogspot.com/2009/05/google-app-engine-java-and-s3.html) that KevMo have suggested uploads whole files to the server but what if my file is 20mb or 100mb. Is it possible to divide that file into 10mb peaces, send them to GAE and then assemble those files on S3 server. Here is the picture of what I'm trying to accomplish here:  Thanks

I'm curious. What could be the reason that a Comparator shuffles entries on each application start? ``` final static class ContactsListComparator implements Comparator { public int compare(Object o1, Object o2) { if((o1.toString().compareTo(o2.toString()))<0) { return -1; } if((o1.toString().compareTo(o2.toString()))>0) { return 1; } else { return 0; } } } ``` First App Start:  Second App Start  As mentioned in one the answer The Comparator actually compares an custom object Contact ``` public class Contact { // Members private String _contactFirstName; private String _contactLastName; private long _contactLastModified; // Constructor public Contact() { set_contactLastModified(); } public Contact(String contactFirstName) { _contactFirstName = contactFirstName; set_contactLastModified(); } // Accessable Getters public String get_contactFirstName() { return _contactFirstName; } public String get_contactLastName() { return _contactLastName; } public long get_contactLastModified() { return _contactLastModified; } public void set_contactLastModified() { _contactLastModified = System.currentTimeMillis(); } } ```

I am trying to build an adhoc build for my app , I am following the instructions on the apple's documentation which says > Select the Target and open the Build settings inspector. In the ‘Code Signing Entitlements’ build setting, type in the filename of the new Entitlements.plist file including the extension. There is no need to specify a path unless you have put the Entitlements.plist file somewhere other than the top level of the project. But i dont see that section , what am i missing ?

I would like to tint an image with a color reference. The results should look like the Multiply blending mode in Photoshop, where would be replaced with :  I will be changing the color value continuously. I would put the code to do this in my ImageView's drawRect: method, right? As always, a would greatly aid in my understanding, as opposed to a link. Subclassing a UIImageView with the code suggested. I put this in viewDidLoad: of my view controller: ``` [self.lena setImage:[UIImage imageNamed:kImageName]]; [self.lena setOverlayColor:[UIColor blueColor]]; [super viewDidLoad]; ``` I see the image, but it is not being tinted. I also tried loading other images, setting the image in IB, and calling setNeedsDisplay: in my view controller. : drawRect: is not being called. I found an old project that had an imageView set up properly so I could test Ramin's code and it works like a charm! For those of you just learning about Core Graphics, here is the simplest thing that could possibly work. In your subclassed UIView: ``` - (void)drawRect:(CGRect)rect { CGContextRef context = UIGraphicsGetCurrentContext(); CGContextSetFillColor(context, CGColorGetComponents([UIColor colorWithRed:0.5 green:0.5 blue:0 alpha:1].CGColor)); // don't make color too saturated CGContextFillRect(context, rect); // draw base [[UIImage imageNamed:@"someImage.png"] drawInRect: rect blendMode:kCGBlendModeOverlay alpha:1.0]; // draw image } ```

I'm trying to figure out the ToolStripSplitButton. The purpose is to display a usercontrol gauge when a ToolStripSplitButton is pressed. However, no matter what settings I try, there is a grey line visible below the button. The ToolStrip itself is set to RenderMode.System, is not docked, and the ToolStripSplitButton is the only component in it. I remove the line by introducing a custom ToolStripRenderer class, but this seems like a total overkill for removing this single annoying dark grey line under the control. I realize it might be a total shot in the dark since I don't provide the rest of the gazillion settings for these components, but I was hoping someone could provide insight into why this control is behaving the way it does. --- My second question is regarding the behaviour of the ToolStripSplitButton. Is there any way to avoid the flat and borderless look that the component displays before the mouse hovers over it? I'm trying to give it a uniform look along with the rest of the buttons in the panel, and the ToolStripSplitButton only appears raised when the mouse cursor is placed above the component. Here's a screenshot:  Any help is greatly appreaciated!

Alex explained what I'm looking for much better than I have: > You want an existing program that allows you to draw a picture, captures what you do as you draw, and writes each action as a Java command. When you click the "Drawl Oval" tool and click at 0,0 and then at 50,50, it would generate the line g.drawOval(0,0,50,50). If anybody knows of a program such as this, let me know. Thanks. --- I've been working with Java and custom drawing using the java.awt.Graphics library lately, but find it is taking too much time to write manually. Is there any simple graphics editor (like mspaint) which generates source code? Example: Drawing this:  Would generate: ``` public void update(Graphics g) { g.translate(0, 0); g.drawOval(0, 0, 50, 50); } ``` Thanks.

I installed the latest version of Wordpress and added the [WP-Syntax](http://wordpress.org/extend/plugins/wp-syntax/) plugin (and also the [Markdown Extra](http://michelf.com/projects/php-markdown/) plugin, but I think it's unrelated to this issue). It works perfectly with both themes that ship with Wordpress: [looking good using WordPress Default 1.6](https://imgur.com/tEPSe.png) and [looking equally good with the WordPress Classic 1.5](https://imgur.com/IOoYG.png) theme. However it doesn't work with the excellent [LightWord](http://wordpress.org/extend/themes/lightword) theme, which I would like to use. The code box looks strange with the right border at the end of the actual code:  I have tried investigating this with Firebug without any success. The CSS from the WP-Syntax plugin should be the same in all three theme cases. So the fact that it looks wierd with this theme has to do with some inherited CSS property from the LightWord theme. This in turn probably means that the WP-Syntax plugin should reset something more for its CSS to work correctly. Advanced CSS isn't something I'm good at. But I would very much like to resolve this problem as soon as possible. I'm also curious from a technical view point what could be causing this behavior? I hope someone with good CSS skills will be able to help out! We (you if you want to, me if you don't feel like it) could then file a bug report in the appropriate place, to get these components working together. To resolve this I understand you need more than screenshots. I have a link with the problem theme, which could be used to investigate further. (Taken down as the problem is solved) In response to a comment I'm also including a link to the working web site using the classic theme and the same plugin setup: (Taken down as the problem is solved) Thank you for reading! ## Summary of problems I'd like to solve: - - `.wp_syntax {width:100%;}`-

The app I'm developing requires that it be deployed in China, which means that it needs to have Pinyin and Chinese character handling. I'm told that the way that our customers handle character entry is like so: - -  - How can I hook such programs (I believe one is called 'mspy.exe', from Microsoft, which I'm lead to believe comes with Microsoft versions of XP) into a WPF text box? Right now, the user can enter text either by using their keyboard or by using an on-screen keyboard, so I will probably need to capture the event of a keypress from either source and feed it to some OS event or to MSPY.exe or some similar program. Or is there some other way to enter pinyin and have it converted to Mandarin? Is there a program other than MSPY I should look at? EDIT: For those of you who think that this should 'just work', it does not. Chinese character entry will work just fine if entering text into notepad or the start->run menu or whatever, but it will not work in WPF. That's the key to this question: how do I enable WPF entry? There's the Google Pinyin and Sogou pinyin, but the websites are in Mandarin or Chinese or something similar and I don't read the language.

I realize this is kind of a long question, but I saw no other way here than to post my code, that I tried to keep as short and simple as possible for the sake of clarity. Of course tons of best practices are violated to do so, the example is long enough as it is.. I made a very simple wpf app that - - - In the following example, I have edited the age of Bar. However, in the List, the age is not updated. If I ask the underlying collection, it still appears to have been updated.. How can I make the list know ?

I want a `div` on the left-hand side of the page as a column, and another `div` to fill the right side of the page. The screenshot that I have attached shows that both in Firefox and IE7 (with scroll bars off), the two `div`s go beyond the boundaries of the screen. I have tried to get a `margin` of `2px` on all sides so that the `border` of the `div` can be seen, but this did not work.  CSS ``` * { margin: 0; } html, form, body { height: 100%; margin:0; padding:0; font-family: "Segoe UI", "Lucida Grande", Helvetica, verdana, sans-serif; font-size: 11px; background: url(/Manage.UI/App_Themes/Default/header.png) no-repeat; overflow: hidden; } #header { height:162px; background: url(/Manage.UI/App_Themes/Default/header.png) no-repeat; } #left { top: 65px; border-width: 1px; border-style: solid; border-color: #c6c6c6; min-height:100%; height: auto !important; height: 100%; width:300px; bottom:100px; left: 2px; position: absolute; float:left; background-color: White; } .wrapper { min-height: 100%; width: 100%; height: auto !important; height: 100%; top: 0px; position: relative; margin: 2px 2px 2px 2px; } #right { top: 65px; border-width: 1px; border-style: solid; border-color: #c6c6c6; height:100%; width:100%; left: 305px; position: absolute; float:right; background-color: White; } ``` And the ASPX Page ``` <body> <form id="form1" runat="server"> <div class="wrapper"> <div id="left"></div> <div id="right"></div> </div> </div> </form> </body> ```

I've written a custom plugin for CKEditor--successful on all fronts, save one currently: I can't, for the life of me, figure out how to customize the image on the button in the toolbar of the editor. As I'm a new user, you'll have to click through to see attached image; the highlighted square in the top left should have a pretty picture (like most of the other toolbar items).

Without any user interaction, how would a program identify what type of waveform is present in a recording from an ADC? For the sake of this question: triangle, square, sine, half-sine, or sawtooth waves of constant frequency. Level and frequency are arbitrary, and they will have noise, small amounts of distortion, and other imperfections.  I'll propose a few (naive) ideas, too, and you can vote them up or down.

I am uploading large files to an ASP.NET server using a standard HTML `<input>` control posting multipart-form data. This is an ASP.NET MVC application. According to MSDN, the `HttpPostedFile` class buffers to disk out of the box: > "Files are uploaded in MIME multipart/form-data format. By default, all requests, including form fields and uploaded files, larger than 256 KB are buffered to disk, rather than held in server memory." I assume this means that when I access `HttpPostedFileBase` in my controller, that when I access the `HttpPostedFileBase`'s `InputStream` property, I can write the file buffer somewhere without having to worry about the server running out of memory, which is obviously an unworkable solution. Here's a bit of pseudocode for how I'm handling each of the incoming files from `HttpPostedFileBase`. ``` for(var i = 0; i< Request.Files.Count;i++) { var fileBase = Request.Files[i]; if (fileBase.ContentLength == 0) { continue; } // One thread per file ThreadPool.QueueUserWorkItem(state => { // Read from fileBase.InputStream }, null); } ``` My web.config's httpRuntime block looks like this: ``` <httpRuntime executionTimeout="1200" requestLengthDiskThreshold="2097151" maxRequestLength="2097151" useFullyQualifiedRedirectUrl="false" minFreeThreads="8" minLocalRequestFreeThreads="4" appRequestQueueLimit="100" /> ``` My implementation works, multiple files are uploaded as expected, except that the same amount of memory required to buffer the entire payload is consumed by the server. I have to assume that the InputStream is buffering everything. When I upload more files than I have memory, it predictably crashes with an `OutOfMemoryException`. Here's an image of the memory spike when uploading an 800mb file.  I know I could use a Flash/Silverlight widget or write a custom `HttpModule` to intercept uploads and handle them myself, but the current requirement would work flawlessly if `HttpPostedFile` did what MSDN says it does (or I'm doing it wrong).

Why doesn't HttpPostedFile perform as advertised and buffer downloads to disk rather than memory?

I sincerly believe that cool-looking UI has significant contribution to the value of your software. It not only significantly improves sales but also ease user-buyin, upgrading willingness, or just causes some pleasant moments to the user. To get cool UI, you will need a lot of images, and you need to play frequently with transparancy.  What image editor do you use/recommend to produce 3D looking images, metalic reflections, glowing text, shadows, or making a button image "disabled-looking"? (freewares are preferred) Could you point to "how-to"-s and guiding documents on how to achieve these visual effects?

I have a layout question for Tab Navigators in Adobe Flex 3. Is it possible to insert a button that invades the grid space of the tabs? I have a tab navigator component and I am dynamically adding sub components to tab navigator and I want squeeze a button inside the tab space. I don't want the button to be another tab. And I don't want to use a TabBar for the tabs. This graphic illustrates the problem. This is the current layout I have  This is a mockup (photoshopped) of the layout I want. I basically want to shave some pixels off the layout.  Is there a way to push the button down or manually override its layout position in MXXML or actionscript?

 Inspired by this [xckd cartoon](http://xkcd.com/612/) I wondered exactly what is the best mechanism to provide an estimate to the user of a file copy / movement? The alt tag on xkcd reads as follows: > They could say "the connection is probably lost," but it's more fun to do naive time-averaging to give you hope that if you wait around for 1,163 hours, it will finally finish. Ignoring the funny, is that really how it's done in Windows? How about other OS? Is there a better way?

This question is related to [Array of pairs of 3 bit elements](https://stackoverflow.com/questions/1053242/array-of-pairs-of-3-bit-elements) This array has 52 pairs (about 40 bytes), and I want to find the first pair before the specified one that has it's values different from 0 (used pair). The obvious solution would be to check each pair < than this one (scan from right to left), but this seems to be very inefficient if there are many unused pairs (set to 0). This image may explain better the situation:  Pairs 0, 1 and 51 are used. I want to find the first used pair before 51 (which is 1 here). I tried tricks like ``` if(*((int *)&array[arrayPos]) == 0) { arrayPos -= sizeof(int); pairPos -= ??? } ``` The problem here is that subtracting from is not that simple, because of the 6 bits/pair, so I ended with a lookup table based on some relations between and , and all this made the solution perform like the trivial one. Is there any way to make this lookup faster ? Another problem is that there is only 1 unused byte... maybe I can make space for another 4. If there were at least 7 I could use a bitmap of the array and it would be much faster to skip over unused pairs.

I am checking whether a user has a permission to view the report through dataset stored procedure and if the user doesn't, raiserror is called. Is there a way to display a different message from SQL Server Reports 2005 when a stored procedure (that populates report dataset) raises error (through RAISERROR) instead of returning data? Here is a skeleton code of dataset stored procedure ``` create procedure ReportSprocName @ClientID int, @Login sysname as begin --; check user's permission through @Login --; * Pseudo code * if @Login does not have permission begin raiserror(@Login does not have permission, 127, 1) return end select id, name, etc... from someTable end GO ``` I am interested in two possibly solutions 1. Displaying error message within RAISERROR 2. Displaying a hardcoded custom message in SSRS report itself Currently this is the default message displayed by SSRS reports

When I'm typing out new instance variables, they appear white. To turn them green, I do a space/backspace between the semicolon. Is there an XCode secret to automatically going through all of my classes and recognize the variables it has missed? Something similar happens with the orange #define variables used throughout code too.  UPDATE: This problem appears to be solved in xcode 3.2 with snow leopard.

Apple's iPhone apps such as Music and Contants use a search bar in a UITableView. When you scroll down so that the search bar moves down, the empty space above the scroll view's contents has a light gray background color (see screenshot).  (Notice that the search bar has a slightly darker edge line at its top. This is not there for the default UISearchBar, but subclassing should take care of that.) I tried setting the background color of the UITableView, but that affects the rows as well. Does anyone know how to achieve this effect? Am I going to have to override implement drawRect: or is there a built in way?

In my example screenshot below I have a single white sphere to be raytraced and a green sphere representing the eye. Rays are drawn as lines with If a ray misses the sphere it is given color in my initialization code I have the following: You can see in the screen shot that for some reason, the rays passing between the perspective view point and the sphere are being color blended with the axis line behind the sphere, rather than with the sphere itself. Here is a screenshot:  Can anyone explain what I am doing wrong here? Thanks!!

In AccuRev, when I look at the history for a file (in "history mode"), I see a list of the actions that were taken on the file. Each action has a number (#) and a version. When I click on one of these actions, another list appears that shows each of the files that was involved in the action (including the one whose history I'm investigating). Each entry in this lower panel has a "virtual version" and a "real version". The "version" in the top panel appears to be the same as the "virtual version" of my file in the lower panel. What is the difference between the #, the virtual version, and the real version? Why do virtual and real versions have two numbers separated by a slash? 

What are the various AccuRev version numbers?

I've designed a website using some Jquery techniques. My problem is that in some random cases, Internet Explorer 8 and 6 can make the images look smaller than they should be. I didn't check with Explorer 7, but it's probably there too... Note that resizing the page might be more liable to cause these problems, and in fact, the client noticed the problem on a 1024x768 resolution monitor. I'm putting the images in a div, and toggling it with Jquery when a URL is clicked, for the animated effect. It works 100% well in Firefox, but randomly looks weird in Explorer. How it should look:  What it ends up looking like:  The Jquery code is below: ``` <script type="text/javascript"> $(document).ready(function() { $('#header').supersleight({shim: 'images/x.gif'}); $('div[class^=images]').hide(); $('a[class=images-importers]').click(function() { $('div[class=images-importers]').toggle(1000); return false; }); $('a[class=images-suppliers]').click(function() { $('div[class=images-suppliers]').toggle(1000); return false; }); }); </script> ``` The HTML for the relevant section is also below: ``` <div> <p> <a href="#" class="images-importers">We are the sole importers of the leading aquatic products in Malta.</a> </p> <div class="images-importers"> <div class="imgcontainer-small"> <a href="..."><img src="..." alt="..." class="glossy" /></a> </div> <div class="imgcontainer-small"> <a href=".../"><img src="..." alt= "..." class="glossy" /></a> </div> <div class="imgcontainer-small"> <a href="..."><img src="..." alt= "..." class="glossy" /></a> </div> </div> </div> ``` The CSS I used for the images : ``` .imgcontainer-small{ text-align : left; padding : 10px; ``` } Thanks for any help!

I am creating RESTful services for several database entities based on a modified version of the [BISDM](http://www.bisdm.org/information/). Some of these entities have associated lookup tables, such as depicted below:  The lookup tables are associated with one and only one table. Additionally, the lookup tables will be used by the client application to populate dropdown lists, treeviews, and comboboxes for the editable fields of their associated entity table. Should lookup values / table get their own URI or should they "share" one with the parent to which they are associated? What are the pros / cons of each? ``` Option 1: /Entities/Spaces/SpaceCategories/ Option 2: /Lookups/SpaceCategories/ ```

When implementing RESTful services should lookup values / tables get their own URI?

I am creating RESTful services for several database entities based on a modified version of the [BISDM](http://www.bisdm.org/information/). Some of these entities have associated lookup tables, such as depicted below:  I have decided to use the repository pattern to provide a clean separation between data persistance / retrieval; however, I am not sure how lookups ( as opposed to entities ) should be represented in the repository. Should lookups get their own repository interface, "share" one with the associated entity, or should there be a generic ILookupRepository interface? For the moment, these lookups are read-only; however, there will be a time where we may want to edit the lookups via services. ``` Option 1: ISpaceRepository.GetSpaceCategoryById(string id); Option 2: ISpaceCategoryRepository.GetById(string id); Option 3: ILookupRepository.GetSpaceCategoryById(string id); ``` Incidentally, this question is related to another one regarding [look-up tables & RESTful web services](https://stackoverflow.com/questions/1168289/when-implementing-restful-services-should-lookup-values-tables-get-their-own-ur).

I have a SharePoint DataView WebPart that is set up to combine data from a few different lists. I want to filter the data to only show data from last week. I am able to filter it to show data from this week, but have been unsuccessful in getting last week's data to show up. I have the web part filter set up like below:  This translates to the following xsl: ``` <xsl:variable name="Rows" select="/dsQueryResponse/Rows/Row[ number(translate(substring-before(@Week_x0020_Starting,'T'),'-','')) &lt;= number(translate(substring-before($Today,'T'),'-','')) and number(translate(substring-before(@Week_x0020_Ending,'T'),'-','')) &gt;= number(translate(substring-before($Today,'T'),'-','')]"/> ``` I speculate that I need to figure out how to do [Current Date] - 7, however I haven't been able to figure out how to do the subtraction. Has anyone encountered a situation similar to this? Am I even going about this correctly?

Its particular query pops up in the slow query log all the time for me. Any way to improve its efficiency? ``` SELECT mov_id, mov_title, GROUP_CONCAT(DISTINCT genres.genre_name) as all_genres, mov_desc, mov_added, mov_thumb, mov_hits, mov_numvotes, mov_totalvote, mov_imdb, mov_release, mov_type FROM movies LEFT JOIN _genres ON movies.mov_id = _genres.gen_movieid LEFT JOIN genres ON _genres.gen_catid = genres.grenre_id WHERE mov_status = 1 AND mov_incomplete = 0 AND mov_type = 1 GROUP BY mov_id ORDER BY mov_added DESC LIMIT 0, 20; ``` My main concern is in regard to the group_concat function, which outputs a comma separated list of genres associated with the particular film, which I put through a for loop and make click-able links.

I'm trying to send a key stroke to one application, through PostMessage. I am using too Spy++ to try to understand how to send the message, as I do not fully understand its inner workings.  In this picture, the first item(selected item) was made with an actual key stroke made by myself. The one with a red elipse around it(below) was made with the following code: ``` WinApi.PostMessage(InsideLobbyHandle, WinApi.WM_KEYDOWN, (int)WinApi.VK_UP, 1); ``` I guess it must have something to do with the last PostMessage() parameter, but I can't figure out how it really works. I can see in the original key stroke the ScanCode = 48, and in mine its 0, and also fExtended is 1 and in mine is 0. How can I make it look the same? In [http://msdn.microsoft.com/en-us/library/ms646280(VS.85).aspx](http://msdn.microsoft.com/en-us/library/ms646280(VS.85).aspx) I cannot understand the last parameter's working.

I'm currently revisiting an area of my Windows-based software and looking at changing the relationship from 1->M to M->M. As a result, I need to adjust the UI to accommodate selecting multiple related records. There are a lot of ways to handle this that are common, but usually pretty clunky. Examples include the two-pane list of all items, and list of selected items, or a list of all records and a checkbox beside each one that applies. In my case, there may be an awful lot (in the tens of thousands) of records that could be associated, so I'll probably need to include some kind of search mechanism. -- I can implement something pretty easily that's functional, I'm looking to see if anyone here has come up with (or seen) any great UIs for doing this kind of thing, whether it's web based, Windows, Mac, Unix, whatever. Images or links to them would be appreciated! Edit: here's an example of what I'm considering:

I have installed and configured NetBeans 6.7 for c++ according to the official manual: [http://www.netbeans.org/community/releases/67/cpp-setup-instructions.html#mingw](http://www.netbeans.org/community/releases/67/cpp-setup-instructions.html#mingw) Configuration window looks like this:  Unfortunately, at 'compile' command following line is displayed: /usr/bin/make -f nbproject/Makefile-Debug.mk SUBPROJECTS= .build-conf BUILD SUCCESSFUL (total time: 642ms) Since i'm on windows and it's no /usr/bin/make, no executable is compiled :(. How to correctly configure NetBeans so it will use make from it's config, not from /usr/bin? Problem is only with mingw/msys toolchain. It works OK with cygwin (same /usr/bin/make message is displayed, but executable IS created). So the question can be changed to: Can Netbeans 6.7 work with mingw on Windows, or i'm limited to cygwin?

I have a tabcontrol binded the an observable list. Eveything look to be perfect until I select a tab. Once selected, the tab doesn't lose its focus and the selected tab is not available. They are not any message in the Output Window. Here is a screen shot just before clicking the tab:  And here is a screen shot after (with the problem):  Any idea about how to resolve this problem or any hint to be able to debug this kind of behavior?

I was recently put in charge of a new project for storing our analytics data. I want to give ORM a shot; the mapping doesn't seem difficult but this problem has me vexed. This database will store data for Google Analytics, Quantcast, and any future analytics provider. I was pretty much given the schema that needs to be used. They want it to be very general which is possible until I store the matrices as we track different ones for each provider. The table layout is as such:  tblClient - Stores all the client websites. tblProfile - 1 or more belong to a client. Stores profile data such as what provider this profile is is using and the profile_type. tblProvider - Stores data as to whether a profile is a GoogleAnalytics, Quantcast, or other analytics profile. tblProfile_Type - The type of track for the client site. We have client sites broken down into different sections. That is tracked here. The problem comes when I need to link the profile table to a metrix table. On this diagram I only have the one for Google but there will be others. I need it to link based on the FK column for Provider_Type in the profile table. Is that possible?

got a strange issue for you. I created a control that inserts a record into a Database and writes a cookie to the user's machine. Here is the cookie writing code snippet: ``` protected void CreateCookie(Guid id, DateTime expires) { var oCookie = new HttpCookie("gsow"); oCookie.Value = id.ToString(); oCookie.Expires = expires; HttpContext.Current.Response.Cookies.Add(oCookie); } ``` Very simple, nothing fancy. The ID is passed from the function that writes the entry into the database and this ID is generated on the fly. Now here is the code for my cookie reading: ``` protected void Page_Load(object sender, EventArgs e) { var oCookie = HttpContext.Current.Response.Cookies["gsow"]; output.Text = "I am Here<br />"; if (oCookie != null) output.Text += oCookie.Value; else output2.Text = "No Cookie."; } ``` Once again, very simple. Here are the steps I have taken and duplicated several times: 1. Create cookie/db entry by launching first page. 2. Verify cookie/db entry exist (they do at this step, checked via Chrome's cookie manager) 3. Launch second page Once I load up the second page, which should spit out the ID that I set earlier, the cookie still exists but it is Unset. Here is a screenshot of the cookie after I load the first page:  And once I load the second page:  So from what I am seeing, the cookie's value/expiration get stripped out when I load the second page. Anyone have any ideas on why this is happening? Thanks

## How to replicate: 1. Create an html5 page. 2. Make sure you have the script from remysharp.com/2009/01/07/html5-enabling-script/ added so that IE will notice the tags. 3. Create an hardcoded <section id='anything'></section> tag. 4. Using jQuery 1.3.2, append another section tag: $('#anything').append('<section id="whatever"></section>'); So far, everything works in all the browsers. 5. Repeat the previous step. $('#whatever').append('<section id="fail"></section>'); This is where IE6/7 fails. Firefox/Safari will continue working. ## Error  ## Thoughts - It could be that IE6/7 can't handle the HTML5 section tag. I say this because when I change step 4 from `<section>` to `<div>`, IE6/7 will start working.- If I use `document.createElement()` and create my new element, it works, but it seems like jQuery's `append()` has a problem with html5 elements.

I am currently working on a Silverlight2-based attendance register. I want to create a visualisation of attendance over time for students and classes, but am struggling to come up with a good way of doing it. The sort of thing I'm imagining is a grid with students on the vertical axis and date along the horizontal, with a symbol at the intersection of student and date indicating presence or absence. Ideally the method used to generate the visualisation would also be used to generate printed material, however this is not essential. (Silverlight has no built-in printing support, so it'd have to be SQL Server Reporting Services or similar.) Here's a simple mock-up in Excel of the sort of data I need to display:  (Obviously with awesome Silverlight styling) Here are my current thoughts on how to go about it: - - - - - - - `......x...oo.ox...x....` Basically every train of thought leads me towards writing my own fully-featured Silverlight/Reporting engine, which is way beyond the scope of what I'm trying to do. Plus I dont really want to leave a future maintainer with some awful custom-built hacky display & reporting system. (I dont want to end up on TheDailyWTF!) This is the sort of visualisation that Silverlight is made for - I just cant decide where to direct my efforts.

What is the best way to display a grid of a large number of items in Silverlight?

I have the css code below along with an image to show it's output. I need help though 2 things. 1. This code works pretty good to show the username on the photo, however I noticed today while using chrome all day often when I would click a link that would take me to the page that has images with this code, it would not show the name on the image, it would just show the name below the image and the transparent black div would not be visible at all and the name would not even be on the image, I would then refresh the page and it would work fine, what could cause this, this was while my PC was acting like it was short on memory, could that be part of the issue? 2. I would like to make a bar show at the top of the image that is the width of the image and like maybe 2-3 pixels tall and have a background color of like blue. What I am wanting to accomplish is for femail users there will be a pink bar over there image and a different color for males. Can someone who knows css help me modify this to do that the best please  ``` <style type="text/css"> div.imageSub { position: relative; } div.imageSub img { z-index: 1; } div.imageSub div { position: absolute; left: 0px; right: 0px; bottom: 0; padding: 5px; height: 5px; line-height: 4px; text-align: center; overflow: hidden; } div.imageSub div.blackbg { z-index: 2; background-color: #000; -ms-filter: "progid:DXImageTransform.Microsoft.Alpha(Opacity=70)"; filter: alpha(opacity=70); opacity: 0.5; } div.imageSub div.label { z-index: 3; color: white; } </style> <div class="imageSub" style="width: 90px;"> <!-- Put Your Image Width --> <img src="http://cache2.mycrib.net/images/image_group66/0/43/t_6871399b0962b5fb4e29ce477541e165950078.jpg" alt="Something" width="90"/> <div class="blackbg"></div> <div class="label">Sara</div> </div> ```

Given a 2d picture of a rectangle distorted by perspective:  I know that the shape was originally a rectangle, but I do not know its original size. If I know the pixel coordinates of the corners in this picture, how can I calculate the original proportions, i.e. the quotient ( width / height ) of the rectangle? (background: the goal is to automatically undistort photos of rectangular documents, edge detection will probably be done with hough transform) # UPDATE: There has been some discussion on whether it is possible at all to determine the width:height ratio with the information given. My naive thought was that it must be possible, since I can think of no way to project for example a 1:4 rectangle onto the quadrangle depicted above. The ratio appears clearly close to 1:1, so there should be a way to determine it mathematically. I have however no proof for this beyond my intuitive guess. I have not yet fully understood the arguments presented below, but I think there must be some implicit assumption that we are missing here and that is interpreted differently. However, after hours of searching, I have finally found some papers relevant to the problem. I am struggling to understand the math used in there, so far without success.

I updated my Sharp-Architecture libraries to the newest version and all of a sudden I'm getting unable to resolve errors - specifically with NHibernate Validators. I am not quite sure why though, here is what my test assembly looks like in reflector:  But the NHibernate.Validator library with the exact same version number/public key is in the same directory!  Any ideas?

Why can't this reference be resolved?

I went from this: [WPF GridViewHeader styling questions](https://stackoverflow.com/questions/1172534/wpf-gridviewheader-styling-questions) to this:  Now I just need to get rid of the white space to the right of the "Size" header. I basically have a template for the GridViewColumnHeader that makes it a TextBlock. Is there any way I can set the background for that header area so that it spans the entire width of the GridView? ADDED CODE: This is my right-most column. The grid does not span 100% of available window area. In the header I need everything to the right of this column to have the same background as the column headers themselves. ``` <Style x:Key="GridHeaderRight" TargetType="{x:Type GridViewColumnHeader}"> <Setter Property="Template"> <Setter.Value> <ControlTemplate TargetType="{x:Type GridViewColumnHeader}"> <TextBlock Text="{TemplateBinding Content}" Padding="5" Width="{TemplateBinding Width}" TextAlignment="Right"> <TextBlock.Background> <LinearGradientBrush StartPoint="0,0" EndPoint="0,1"> <GradientStop Offset="0.0" Color="#373638" /> <GradientStop Offset="1.0" Color="#77797B" /> </LinearGradientBrush> </TextBlock.Background> </TextBlock> </ControlTemplate> </Setter.Value> </Setter> <Setter Property="OverridesDefaultStyle" Value="True" /> <Setter Property="Background" Value="Green" /> <Setter Property="Foreground" Value="White" /> <Setter Property="FontSize" Value="12" /> <Setter Property="Background"> <Setter.Value> <LinearGradientBrush StartPoint="0,0" EndPoint="0,1"> <GradientStop Offset="0.0" Color="#373638" /> <GradientStop Offset="1.0" Color="#77797B" /> </LinearGradientBrush> </Setter.Value> </Setter> </Style> <GridViewColumn Width="200" HeaderContainerStyle="{ StaticResource GridHeaderRight}" Header="Size"> <GridViewColumn.CellTemplate> <DataTemplate> <TextBlock Text="{Binding Path=EmployeeNumber}" HorizontalAlignment="Right"></TextBlock> </DataTemplate> </GridViewColumn.CellTemplate> </GridViewColumn> ``` I am one step closer (I think) to solving this. I added the following code inside the GridView tag: ``` <GridView.ColumnHeaderContainerStyle> <Style TargetType="GridViewColumnHeader"> <Setter Property="BorderThickness" Value="1"></Setter> <Setter Property="BorderBrush" Value="Green"></Setter> <Setter Property="Height" Value="Auto"></Setter> <Setter Property="Background"> <Setter.Value> <LinearGradientBrush StartPoint="0,0" EndPoint="0,1"> <GradientStop Offset="0.0" Color="#373638" /> <GradientStop Offset="1.0" Color="#77797B" /> </LinearGradientBrush> </Setter.Value> </Setter> </Style> </GridView.ColumnHeaderContainerStyle> ``` The border is there just so you can see the boundary of what this style covers. This is an enlarged image of what this does. It seems to be what I want if I can get rid of the little white border on the bottom. So I guess removing that tiny white bottom border would also be an accepted answer for this one.

How do you style a WPF GridView Header?

Microsoft.SqlServer.SqlTools.VSIntegration.dll contains a namespace `Microsoft.SqlServer.Management.UI.VSIntegration`, which in turn contains ServiceCache (public sealed). As soon as I add the reference, ServiceCache is highlighted (meaning there is no reference issue) But the problem arises when I compile the project and VS 2010 throws up an error that it cannot find ServiceCache. > The name 'ServiceCache' does not exist in the current context Why is that ServiceCache is not visible during compile time but looks like it's available right after adding the assembly? And Reflector does show that ServiceCache is part of the assembly that the project is referencing, but Visual Studio intellisense fails to display it. Any had this kind of problem? Some screenshots Reflector clearly shows `ServiceCache`  But Visual Studio 2010 says, otherwise...

I don't want overlapping nodes, so the question is how to arrange space in an optimal way.

First of all, as I am using VB6, please confine your kind suggestions to techniques applied to VB6.  I have a set of controls related to each other as the above figure shows. It includes several treeviews, a split bar, a listview, a subform( a usercontrol), and etc. When I click or change the treeview nodes in the left, the right controls will change their display accordingly, and vice versa. The data behind the scene is maintained in an Access database. This set of data management and display is used in several different applications. So I wrote several classes to implement the logic and include these classes modules again and again in my applications. So I am actually my classes in a "copy and paste" mode. It works but it have problems. If I make a change in a class, I have to change it in several applications. These days I am thinking about making them into the so-called ActiveX components. But I am not sure which kind of ActiveX components should I develop to reuse the whole architecture. In a nutshell, I want to know than just "copy and paste". Below is some ideas or expectation of the new "graceful REUSE", but not confine to them. (1) I hope it looks like an ActiveX control which has a property page so that I can set some properties of it during design time. (2) For different applications, the subform in the right may display different information and has different controls and may need extra coding and designing. (3) Also I may need to code some new behaviour for the treeview and listview for different applications. This requirement make a whole usercontrol for the whole form not suitable. because MSDN said “References to ActiveX controls，should never be returned to client applications。"

How can I reuse classes in my VB6 application?

I implemented a custom DateTimePicker. On the DateTimePicker there is a button. In the examples I've found it's width is set to 16. This is working but I would like to have a dynamic approach. So, is there a way to get the size of this button or is there a general way to get information about .Net-Control sub elements like size etc.? Trying DateTimePicker.Controls didn't help me (it's empty).

Here is how my menu looks right now:  Here is how I want it to look:  Right now I have the following css: ``` #menu { position:relative; width: 940px; height:90px; } #menuItem { position: absolute; bottom: 0px; padding-left: 50px; float: left; width: 600px; } .titleText { float: right; color:#209202; font-size:22px; font-style:italic; font-family:Georgia; font-weight:bold; } ``` And the following HTML: ``` <div id="titleBar"> <div id="menu"> <div id="menuItem"> <ul class="tabs"> <li><a href="/dashboard/"> <img alt="Dashboard" src="/Content/Images/Dashboard_green.png" /> </a> </li> <li><a href="/placements/"> <img alt="Place Accounts" src="/Content/Images/Place_Accounts_white.png" /> </a> </li> <li><a href="/messages"> <img alt="Messages" src="/Content/Images/Messages_white.png" /> </a> </li> <li><a href="/reports"> <img alt="Reports" src="/Content/Images/Reports_white.png" /> </a> </li> <li><a href="/admin"> <img alt="Admin" src="/Content/Images/Admin_white.png" /> </a> </li> </ul> </div> <div class="titleText"> Dashboard </div> </div> </div> ``` I've tried a million different things to get titleText 40px from the right hand side and 50px from the top, and having the tabs floating 40px from the left bottom, but everything I try gets me close but then fails to work in IE7 for some reason. menu represents the whole grey bar area. menuItem is the tabs. titleText is the green word that says "Dashboard". I should I style menuItem, menu, and titleText so it displays like the correct image below and still works in IE7? Any assistance would be greatly appreciated. I've been trying at this blindly for awhile.

How can I make these elements line up correctly using CSS?

I'm trying unsuccessfully to get CoverStory working in an iPhone project. Unfortunately XCode build settings and gcc flags are a big mystery to me. :( I've managed to generate .gcno files but the .gcda files don't show. I've added -lgcov as an other linker flag, set both the GCC_GENERATE_TEST_COVERAGE_FILES and GCC_INSTRUMENT_PROGRAM_FLOW_ARCS flags to YES as specified in the documentation but I still have no luck. I also downloaded the fat libgcov.a file from CoverStory's site and included that in my project. I am trying this with the new built in support for iPhone unit tests using a logic unit test bundle. Could this be the cause? Does the app need to run as an application in order to generate these files?

Given a database schema with a parent table and two or more child tables. For example:  Is it possible to create a query, using the `for xml` statement, that outputs the following XML: ``` <?xml version="1.0"?> <person> <name>Joe Bloggs</name> <age>25</age> <address> <streetAddress>123 Test Street</streetAddress> <town>Example Town</town> <postcode>A12 3BC</postcode> </address> <address> <streetAddress>124 Test Street</streetAddress> <town>Example Town</town> <postcode>A12 3BC</postcode> </address> <contact> <type>Home Phone</type> <value>01234 567890</value> </contact> <contact> <type>Work Phone</type> <value>01987 654321</value> </contact> <contact> <type>Email Address</type> <value>joe@example.com</value> </contact> </person> ``` My initial attempt: ``` select person.name, person.age, address.streetAddress, address.town, address.postcode, contact.type, contact.value from Person as person left join Address as address on person.PersonID = address.PersonID left join Contact as contact on person.PersonID = contact.PersonID where person.PersonID = 1 for xml auto, elements ``` Yielded this result in which all the combinations of contact and address are output: ``` <?xml version="1.0" encoding="utf-8"?> <person> <name>Joe Bloggs</name> <age>25</age> <address> <streetAddress>123 Test Street</streetAddress> <town>Example Town</town> <postcode>A12 3BC</postcode> <contact> <type>Home Phone</type> <value>01234 567890</value> </contact> <contact> <type>Work Phone</type> <value>01987 654321</value> </contact> <contact> <type>Email Address</type> <value>joe@example.com</value> </contact> </address> <address> <streetAddress>124 Test Street</streetAddress> <town>Example Town</town> <postcode>A32 1BC</postcode> <contact> <type>Home Phone</type> <value>01234 567890</value> </contact> <contact> <type>Work Phone</type> <value>01987 654321</value> </contact> <contact> <type>Email Address</type> <value>joe@example.com</value> </contact> </address> </person> ``` Using a single left join to either the Contact or Address table produces part of what I'm after, but after adding the second join it starts to go wrong. Is there another technique that could be used to achieve the result I'm looking for?

I am building a website for a club that is part of a mother organisation. I am downloading (leeching ;) ) the images that where put on profile pages of the mother organisation to show on my own page. But their website has a nice white background, and my website has a nice gray gradient on the background. This does not match nicely. So my idea was to edit the images before saving them to my server. I am using GDI+ to enhance my images, and when I use the method MakeTransparent of Bitmap, it does work, and it does do what its supposed to do, but I still have these white jpeg artifacts all over the place. The artifacts makes the image so bad, I am better off not making the image transparent and just leaving it white, but thats really ugly on my own website. I can always at a nice border with a white background of course, but I rather change the background to transparent. So I was wondering if and how I can remove some simple JPEG artifacts in C#. Has anyone ever done this before? Thanks for your time. Example image:  Transformed image:

I working on a simple paint program. It seemed Qt (and KDE) would be a easy way to implement it. I find Qt quite easy to work with, but now I have hit a problem. When I draw something in my program the mouse skips if I move the mouse to fast. like this:  It susposed to be like one long string. I'm using mouseMoveEvent() to draw a pixel to my image when the left mouse button is pressed down. I have called setMouseTracking(true); so the event should be called as long as I move the mouse. ``` void camoMaker::mouseMoveEvent(QMouseEvent *ev) { if(ev->state()==Qt::LeftButton) { QPoint mPoint=ev->pos(); mPoint.setX(mPoint.x()-80); drawPoint(mPoint); } } ``` camoMaker is the main widget. drawPoint() draws a pixel on both a internal QImage and using QPainter on a QWidget thats the drawing area. It seems to me that either mouseMoveEvent() isn't called for every pixel the mouse moves or that the mouse actually just skips some pixel. I understand that it might just how it works and not Qt fault but X11 or how the OS handle mouse position/input. If so how would I go about to fix it, should I try to interpolate from 2 points that gets registered?

I'm desperately trying to connect controls of NSViews which will reside in a NSCollectionView using outlets. The collection view is fed using an NSArrayController. I created the NSView in a separate NIB file and in the implementation of NSCollectionViewItem I overwrote copyWithZone to load it: ``` -(id)copyWithZone:(NSZone *)zone { id result = [super copyWithZone:zone]; [NSBundle loadNibNamed:@"InputView" owner:result]; return result; } ``` I've used this approach according to this [instructions](http://benedictcohen.co.uk/blog/archives/72). Unfortunately this is what happening:  The NSView looks like this:  The NSCollectionView resides in a NSScrollView and the scrollbar is set to enable automatically. But as you can see there's no scrollbar. I don't really understand what I need to do so the NSCollectionView knows the dimensions of its NSViews. It has worked before when I didn't have a seperate NIB-file, but then I couldn't make outlet connections from the view to the item :-(

I've been trying a lot of different things that I would think would work like expected. However, they are causing me some frustration. Here's the scoop: I am using ICEFaces 1.8 components in a Java EE web application. My goal is to render a bunch of ice:commandButtons on the page based on a query to my database. I want these buttons to be able to toggle selections that I will later use for parameters to another query to the database (basically a query front end of sorts for a set of users). I would like the output to look like so:  When I click on a button, I would like the following update to my page:  When I created the buttons on my page statically, as such: ``` <ice:commandButton id="seasonSEP09" style="background-color: #FFFFFF;" partialSubmit="true" actionListener="#{bean.updateSeasons}" value="2009-2010" /> <ice:commandButton id="seasonSEP08" style="background-color: #FFFFFF;" partialSubmit="true" actionListener="#{bean.updateSeasons}" value="2008-2009" /> <ice:commandButton id="seasonSEP07" style="background-color: #FFFFFF;" partialSubmit="true" actionListener="#{bean.updateSeasons}" value="2007-2008" /> <ice:commandButton id="seasonSEP06" style="background-color: #FFFFFF;" partialSubmit="true" actionListener="#{bean.updateSeasons}" value="2006-2007" /> ``` this works great, and each button works individually as I would expect. My backing bean is updated, the parameters are correctly added in updateSeasons() method, and my output at the end yields the correct records. However, I know this is not what I want. I don't want to update these anytime another season is entered in the system. Maintainance nightmare, right? So what I want to do is dynamically generate these ice:commandButton components based on my database table full of Season objects. Here is the Season class I am using: ``` public class Season { String StartMonth; String Season; public String getStartMonth() { return StartMonth; } public void setStartMonth(String startMonth) { StartMonth = sweep; } public void setSeason(String season) { Season = season; } public String getSeason() { return Season; } } ``` Very straightforward. Two properties, which I'm guaranteed to be unique in the database. Here is the backing bean I am using: ``` public class Bean { public Bean() { defineSeasonsList(); } public List<HtmlCommandButton> seasonsList; // seasonsList getter & setter omitted public List<String> selectedSeasons; // selectedSeasons getter & setter omitted private void defineSeasonsList() { seasonsList = new ArrayList<HtmlCommandButton>(); selectedSeasons = new ArrayList<String>(); try { hibernate.openTransaction(); for(Season season:defineSeasonsListFromDataSource())) { HtmlCommandButton button = new HtmlCommandButton(); button.setId("season" + season.getStartMonth()); button.setValue(season.getSeason); button.setStyle("background-color: #FFFFFF;"); button.setPartialSubmit(true); seasonsList.add(button); } } catch (Exception e) { System.out.println("Error defining seasons list: " + e.getMessage()); } finally { hibernate.commitTransaction(); } } public void updateSeasons(ActionEvent ae) { HtmlCommandButton selected = (HtmlCommandButton) ae.getComponent(); if(selectedSeasons.contains(selected.getValue().toString())) { selectedSeasons.remove(selected.getValue().toString()); selected.setStyle("background: #FFFFFF;"); } else { selectedSeasons.add(selected.getValue().toString()); selected.setStyle("background: #009DD9; color: #FFFFFF;"); } } } ``` OK, so here comes my dilemma(s). First, I tried to render this markup: ``` <p> <ice:panelGroup> <ice:panelSeries id="seasonsList" value="#{bean.seasonsList}" var="season"> <ice:commandButton binding="#{season}"/> </ice:panelSeries> </ice:panelGroup> </p> ``` And I get this output:  So, being frustrated and adventurous, I tried to render this markup to achieve my goal: ``` <p> <ice:panelGroup> <ice:panelSeries id="seasonsList" value="#{bean.seasonsList}" var="season"> <ice:commandButton id="#{season.id}" partialSubmit="true" style="background-color: #FFFFFF" value="#{season.value}" actionListener="#{bean.updateSeasons}"/> </ice:panelSeries> </ice:panelGroup> </p> ``` Which yielded the following stacktrace: Aug 4, 2009 2:28:11 PM com.sun.faces.lifecycle.Phase doPhase SEVERE: JSF1054: (Phase ID: RENDER_RESPONSE 6, View

Thanks in advance, my friends. : So I tried changing the seasonsList collection from List to List and rendering some different markup, like so: ``` <p> <ice:panelGroup> <ice:panelSeries value="#{bean.seasonsList}" var="season"> <ice:commandButton partialSubmit="true" style="background-color: #FFFFFF" value="#{season}" actionListener="#{Phase1EventBean.updateSeasons}"/> </ice:panelSeries> </ice:panelGroup> </p> ``` And changing the defineSeasonsList() method to: ``` public void defineNationalSeasonsList() { try { seasonsList = new ArrayList<String>(); selectedSeasonsList = new ArrayList<String>(); hibernate.openTransaction(); for(UedaNationalDates season:hibernate.getList(new UedaNationalDates(), QueryFactory.getUedaNationalSeasons(hibernate.getHibSession()))) { nationalSeasonsList.add(season.getSeason()); } } catch (Exception e) { System.out.println("Error defining nationalMeasurementPeriods: " + e.getMessage()); } finally { hibernate.commitTransaction(); } } ``` This actually renders all the buttons I would like to see, and adds them correctly to the selectedSeasonsList in my backing bean when I click on them, and removes them from it when I click again. However, on the UI, button appears to be toggled when I click just the one button. For example, when I click on 2009-2010, this is what I see:

I'm trying to convert an image into an audio signal in MATLAB by treating it as a spectrogram [as in Aphex Twin's song on Windowlicker](http://www.bastwood.com/aphex.php). Unfortunately, I'm having trouble getting a result. Here it what I have at the moment: ``` function signal = imagetosignal(path, format) % Read in the image and make it symmetric. image = imread(path, format); image = [image; flipud(image)]; [row, column] = size(image); signal = []; % Take the ifft of each column of pixels and piece together the real-valued results. for i = 1 : column spectrogramWindow = image(:, i); R = abs(ifft(spectrogramWindow)); % Take only the results for the positive frequencies. signalWindow = R(1 : row / 2.0); signal = [signal; signalWindow]; end end ``` So, I'm taking Inverse Fourier Transforms on columns of my image and then putting them together to form a signal. Also, this function uses the Image Processing Toolbox for MATLAB to read in images. The goal is to have some variation of ``` spectrogram(imagetosignal('image', 'bmp')); ``` result in something that looks like the original image. I would very much appreciate any help! I'm just learning signal processing, so don't be surprised if there's an obvious misconception. Thanks! --- : Thanks Dave! I got it working! I ended up with this: ``` function signal = imagetosignal(path, format) % Read in the image and make it symmetric. image = imread(path, format); image = [image; flipud(image)]; [row, column] = size(image); signal = []; % Take the ifft of each column of pixels and piece together the results. for i = 1 : column spectrogramWindow = image(:, i); signalWindow = real(ifft(spectrogramWindow)); signal = [signal; signalWindow]; end end ```

I have a table that looks like this:  ClientID is the only identity column I have in the table. UserID is a FK to a different tables primary key. Here is my Linq to SQL insert code: ``` public void InsertClientByUsername(string username, Entities.Client clientInfo) { using (LinqModelDataContext db = new LinqModelDataContext()) { var existingClient = (from client in db.Clients join ext_usr in db.User_Extendeds on client.UserID equals ext_usr.FriendlyUserID join asp_usr in db.aspnet_Users on ext_usr.UserID equals asp_usr.UserId where asp_usr.UserName.ToLower().Equals(username) select client).SingleOrDefault(); if (existingClient != null) { existingClient.Address1 = clientInfo.Address1; existingClient.Address2 = clientInfo.Address2; existingClient.City = clientInfo.City; existingClient.CompanyName = clientInfo.CompanyName; existingClient.CountryID = clientInfo.CountryID; existingClient.FaxNumber = clientInfo.Fax; existingClient.FirstName = clientInfo.FirstName; existingClient.LastName = clientInfo.LastName; existingClient.MailingAttention = clientInfo.Attention; existingClient.PhoneNumber = clientInfo.PhoneNumber; existingClient.StateID = clientInfo.StateID; existingClient.ZipCode = clientInfo.Zip; } else { int userID = (from ext_usr in db.User_Extendeds join asp_usr in db.aspnet_Users on ext_usr.UserID equals asp_usr.UserId where asp_usr.UserName.ToLower().Equals(username) select ext_usr.FriendlyUserID).SingleOrDefault(); Client newClient = new Client(); newClient.UserID = userID; newClient.Address1 = clientInfo.Address1; newClient.Address2 = clientInfo.Address2; newClient.City = clientInfo.City; newClient.CompanyName = clientInfo.CompanyName; newClient.CountryID = clientInfo.CountryID; newClient.FaxNumber = clientInfo.Fax; newClient.FirstName = clientInfo.FirstName; newClient.LastName = clientInfo.LastName; newClient.MailingAttention = clientInfo.Attention; newClient.PhoneNumber = clientInfo.PhoneNumber; newClient.StateID = clientInfo.StateID; newClient.ZipCode = clientInfo.Zip; db.Clients.InsertOnSubmit(newClient); } db.SubmitChanges(); } } ``` In case you are curious, the reason I have all those assignments is because I'm translating between my POCO domain objects and the linq generated objects. In the case of this exception, it is taking the path of the else statement, creating a new client. You can see that I'm touching the ClientID property which is the ~only~ identity column in the table.

I am playing around with Sharepoint 2007. I have a virtual machine (win server 2k3) with an instance of sharepoint server 2007 running on it. I am now working on creating web parts. I have successfully created simple ones, such as this one that displays text: ``` public class SimpleWebPart : WebPart { private string _displayText = "Hello World!"; [WebBrowsable(true), Personalizable(true)] public string DisplayText { get { return _displayText; } set { _displayText = value; } } protected override void Render(System.Web.UI.HtmlTextWriter writer) { writer.Write(_displayText); } } ``` I have this one (and a few test ones) inside of a Class Library, which I put into the `_app_bin` folder inside of `C:\Inetpub\wwwroot\wss\VirtualDirectories\80`. The latest one I added utilizes LINQ to get data from a table I added (not part of Sharepoint): ``` public class SimpleDBWebPart : WebPart { protected override void Render(System.Web.UI.HtmlTextWriter writer) { var oDB = new SPWebPartDataClassesDataContext(); var oRes = oDB.GetAllFirstTable(); foreach(var item in oRes) { writer.Write("<div>Item Name: {0}</div>",item.text); writer.Write("<div>Item ID: {0}</div>", item.id); } } } ``` The `GetAllFirstTable()` is a stored procedure that gets all the data from my test table: ``` ALTER PROCEDURE dbo.GetAllFirstTable AS SELECT * FROM FirstTable RETURN ``` When I try to add the WebPart to a page, I get this error: > The "SimpleDBWebPart" Web Part appears to be causing a problem. Could not load file or assembly 'System.Data.Linq, Version=3.5.0.0, Culture=neutral, PublicKeyToken=b77a5c561934e089' or one of its dependencies. The system cannot find the file specified. I used Reflector to make sure I have the assembly inside the DLL:  And that appears to be the case. Do I have to add the assembly to the web.config file of the sharepoint site? Or is there something else that I am missing? Thanks guys!

So I'm working on a project that will, in the end, generate a kind of flow chart using the Flickr api. You will supply a seed tag, and the program will use that seed tag to find other related Flickr pictures that have common tags... I have all of the back end stuff up and running but I'm stumped on the formatting. Here is a screenie of what I would like it to look like...  Here's my question. Is there a good way of approaching the spacing of each branch? By this is mean, I would like to have a function where I could simply create a new node (or "branch") and specify which existing node I would like it to attach to. This is all good and fine, but I need to be able to automatically and intelligently place the new node on the page so it doesn't overlap any existing lines or nodes. I guess this is more of a general programming question as if I knew the process I could code it, but for those who are interested I am doing this in Javascript/HTML/CSS for the styling and maybe some PHP for the Flickr calls. Feel free to ask any questions to clarify my rambling.

I have this dilemma about designing/programming border or gap widths in an application of mine. I'm using Swing but this is sort of implementation-agnostic. I have a splitter pane (JXMultiSplitPane) dividing two subpanes, shown below outlined in black; the black border will be gone in the real application and is just here for debugging. You'll note that there's a gap between the two subpanes. That's the splitter, and it needs to be wide enough to grap onto. You'll also notice the gap between each table and the black border. That's supposed to be there to add some reasonable space... except that if I remove the black borders, I now have a space between the two tables that looks 3x as wide as it should be. My instinct is to get rid of the gap on the right side of the left-hand table, and the gap on the left side of the right hand table, so that the only gap is the splitter itself. Is this the right way to handle it? The only hesitation I have is that I may be giving the user the option to stack these vertically, so the actual border spacing of the left hand table needs to change (spacing adjacent to the splitter should be set to 0) and that seems weird....

The iPhone is admittedly not the best platform for viewing code, but I'd like to optimize the mobile portion of my web site for the device as best I can. I'm having trouble getting code (Java code, in this case) to display properly. I'm using `<pre>` tags, along with some CSS to render a nice little background for the code. This looks OK:  However if you scroll to see the rest of the code, you get this:  The text inside the `<pre>` is rendered properly, but the background color stops at the width of the device. I have tried this in the simulator, in a 3G device running 3.0, as well as in a 3G running 3.1-beta and they all behave this way. It render fine in Safari on the Mac; just not on the iPhone. Here is the HTML: ``` <pre> String input = readUserInput(); // assume defined elsewhere int i; try { i = Integer.parseInt(input); } catch (NumberFormatException exception) { System.err.println("You entered an invalid integer: " + exception.getMessage()); } </pre> ``` And the CSS: ``` pre { font-weight: bold; border: 2px solid green; background: #669999; padding: 5px; } ```

I want to use partially transparent images in drag/drop operations. This is all set up and works fine, but the actual transformation to transparency has a weird side effect. For some reason, the pixels seem to be blended against a black background. The following image describes the problem:  Figure a) is the original bitmap. Figure b) is what is produced after alpha blending has been performed. Obviously this is a lot darker than the intended 50% alpha filter intended. Figure c) is the desired effect, image a) with 50% transparency (added to the composition with a drawing program). The code I use to produce the trasparent image is the following: ``` Bitmap bmpNew = new Bitmap(bmpOriginal.Width, bmpOriginal.Height); Graphics g = Graphics.FromImage(bmpNew); // Making the bitmap 50% transparent: float[][] ptsArray ={ new float[] {1, 0, 0, 0, 0}, // Red new float[] {0, 1, 0, 0, 0}, // Green new float[] {0, 0, 1, 0, 0}, // Blue new float[] {0, 0, 0, 0.5f, 0}, // Alpha new float[] {0, 0, 0, 0, 1} // Brightness }; ColorMatrix clrMatrix = new ColorMatrix(ptsArray); ImageAttributes imgAttributes = new ImageAttributes(); imgAttributes.SetColorMatrix(clrMatrix, ColorMatrixFlag.Default, ColorAdjustType.Bitmap); g.DrawImage(bmpOriginal, new Rectangle(0, 0, bmpOriginal.Width, bmpOriginal.Height), 0, 0, bmpOriginal.Width, bmpOriginal.Height, GraphicsUnit.Pixel, imgAttributes); Cursors.Default.Draw(g, new Rectangle(bmpOriginal.Width / 2 - 8, bmpOriginal.Height / 2 - 8, 32, 32)); g.Dispose(); imgAttributes.Dispose(); return bmpNew; ``` Does anyone know why the alpha blending does not work? For clarity, the code does work if I'm alphablending on top of a drawn surface. The problem is that I want to create a completely semitransparent image from an existing image and use this as a dynamic cursor during drag/drop operations. Even skipping the above and only painting a filled rectangle of color 88ffffff yields a dark grey color. Something fishy is going on with the icon. Since I've reseached a whole lot and believe this has got something to do with the Cursor creation, I'm gonna include that code below too. If I GetPixel-sample the bitmap just before the CreateIconIndirect call, the four color values seem to be intact. Thus I have a feeling the culprits might be the hbmColor or the hbmMask members of the IconInfo structure. Here's the IconInfo structure: ``` public struct IconInfo { // http://msdn.microsoft.com/en-us/library/ms648052(VS.85).aspx public bool fIcon; // Icon or cursor. True = Icon, False = Cursor public int xHotspot; public int yHotspot; public IntPtr hbmMask; // Specifies the icon bitmask bitmap. If this structure defines a black and white icon, // this bitmask is formatted so that the upper half is the icon AND bitmask and the lower // half is the icon XOR bitmask. Under this condition, the height should be an even multiple of two. // If this structure defines a color icon, this mask only defines the AND bitmask of the icon. public IntPtr hbmColor; // Handle to the icon color bitmap. This member can be optional if this structure defines a black // and white icon. The AND bitmask of hbmMask is applied with the SRCAND flag to the destination; // subsequently, the color bitmap is applied (using XOR) to the destination by using the SRCINVERT flag. } ``` And here is the code that actually creates the Cursor: ``` public static Cursor CreateCursor(Bitmap bmp, int xHotSpot, int yHotSpot) { IconInfo iconInfo = new IconInfo(); GetIconInfo(bmp.GetHicon(), ref iconInfo); iconInfo.hbmColor = (IntPtr)0; iconInfo.hbmMask = bmp.GetHbitmap(); iconInfo.xHotspot = xHotSpot; iconInfo.yHotspot = yHotSpot; iconInfo.fIcon = false; return new Cursor(CreateIconIndirect(ref iconInfo)); } ``` The two external functions are defined as follows: ``` [DllImport("user32.dll", EntryPoint = "CreateIconIndirect")] public static extern IntPtr CreateIconIndirect(ref IconInfo icon); [DllImport("user32.dll")] [return: MarshalAs(UnmanagedType.Bool)] public static extern bool GetIconInfo(IntPtr hIcon, ref IconInfo pIconInfo); ```

I'm a person that learns best from example. Currently, I'm diving into the field of Web Development after fifteen years of developing desktop apps. I'm still getting used to all the web technologies used for developing modern web sites and everywhere I look, I see cool little UI elements and question how they're implemented. So I thought I'd ask you, the web experts...the wexperts :) What are some straight forward or creative ways you could code this grid-breaking arrow...  The basic layout for this page looks like...  1. What would the html/css code look like? 2. Would you split the image into multiple images or could you use a single image? I'm sure this is a really simple concept and it completely boggles me. I'm sorry if this is a strange question, remember I'm a noob! :) Thanks in advance for all your help! Here's a [link](http://psdtuts.com/tutorials/interface-tutorials/how-a-simple-layout-can-be-mixed-n-matched-with-patterns-photos-and-backgrounds/) to the original tutorial where I found these images

I have been playing around with the idea of a single audit table for a few tables in my database. I found the code on this page: [http://www.simple-talk.com/sql/database-administration/pop-rivetts-sql-server-faq-no.5-pop-on-the-audit-trail/](http://www.simple-talk.com/sql/database-administration/pop-rivetts-sql-server-faq-no.5-pop-on-the-audit-trail/) I like the idea, but the only that I am a bit puzzled with is how you would query out the information so that it can be shown in a useful manner. After you make some changes the audit table looks like this:  Most of the time in order to do history I would just make a copy of table and add a date modified column to the end then just copy the whole row into the history table, but that creates a lot of copied data and lots of history tables if you have lots of things to audit.

This is an idea I have been thinking about, but I do not quite know how to solve it. I would like to know if any solutions like this exists out there, or if you guys have any idea how this could be implemented. ### Steganography Steganography is basically the art of hiding messages. In modern days we do this digitally by e.g. modifying the least significant bits in a image as the one below. Thus for every pixel and for every colour component of that pixel we might be able to hide a byte or two. This alternation is not visibly by the naked eye, but analysing the least significant bits might reveal patterns that exposes the existence and possibly content of a hidden message. To counter this we simply encrypt the message before embedding it in the image, which keeps the message safe and also helps preventing discovery of the existence of a hidden message. Thus, in principle, steganography provides the following: - - - [](https://i.stack.imgur.com/icplF.jpg) [cs.vu.nl](http://www.cs.vu.nl/~ast/books/mos2/zebras.jpg) ### Semacodes Semacodes are a way of encoding data in a visually representation, that may be printed, copied, and scanned easily. The Data Matrix shown below is a example of a semacode containing the famous Lorem Ipsum text. This is essentially a 2D barcode with a higher capacity that usually barcodes. Programs for generating semacodes are readily available, and ditto for software for reading them, especially for cell phones. Semacodes usually contains error correcting codes, are generally very robust, and can be read in very damaged conditions. Thus semacodes has the following properties: - -  ### Combining it So my idea is to create something that combines these two, with all of the combined properties. This means it would have to: - - - So, first of all I would like to know if any solutions, algorithms or research is available on this? Secondly I would like to hear any ideas/thoughts on how this might be done? I really hope to get a good discussion going on the possibilities and feasibility of implementing something like this, and I am looking forward to reading your answers. ## Update Thanks for all the good input on this. I will probably work a bit more on this idea when I have more time. I am convinced it must be possible. Think about research in embedding watermarks in music and movies.

I have a CSS issue which occurs in IE6 only. I'm completely stumped and am hoping someone else might be able to help. In IE6, if you navigate to www.moneysupermarket.com/loans and search for a loan of £5000 over 5 years, Homeowner - Mortgaged, you will get the Loans results page. Scroll to the bottom of the page and you will see the Personal Pricing results table. How it should and is appearing:  If it looks right when the page loads, clicking onto one of the other tabs knocks it out. Annoyingly the IE6 developer toolbar isn't much use. As soon as I change any of the styles on the UL or LI that make up the tabs, it looks fine. If I make the same change in the CSS file and refresh, it doesn't seem to work. I'm aware of the hasLayout issue, but setting display:inline-block, or height:1% to elements doesn't seem to be doing anything. Any suggestions or assistance would be appreciated! Thanks

I have a RadGrid with a datatable as it's source. I have AllowCustomPaging set to true. ``` <telerik:RadGrid runat="server" ID="RadGridSearchResults" PageSize="50" AllowPaging="true" AllowCustomPaging="true" OnNeedDataSource="RadGridSearchResults_NeedDataSource" Skin="Default"> <PagerStyle Mode="NextPrevNumericAndAdvanced" /> </telerik:RadGrid> ``` The code for my code behind method RadGridSearchResults_NeedDataSource just fills and returns a datatable with the following columns: ``` dataTableSearchResults.Columns.Add("recipeId", typeof(string)); dataTableSearchResults.Columns.Add("ingredientsIds", typeof(string)); dataTableSearchResults.Columns.Add("country", typeof(string)); dataTableSearchResults.Columns.Add("author", typeof(string)); dataTableSearchResults.Columns.Add("style", typeof(string)); dataTableSearchResults.Columns.Add("friendly", typeof(string)); dataTableSearchResults.Columns.Add("name", typeof(string)); ``` Once the RadGrid is databound, I run the following: ``` var expression = GridGroupByExpression.Parse( "recipeId [Recipe], count(recipeId) ingredientsIds [Ingredients] Group By recipeId"); this.RadGridSearchResults.MasterTableView.GroupByExpressions.Add(expression); this.RadGridSearchResults.GroupingEnabled = true; ``` I would expect my radgrid to then look like the one they [have here](http://demos.telerik.com/aspnet-ajax/grid/examples/groupby/expressions/defaultcs.aspx) once you click on the 'Group by expression' button: Instead, it looks like this:  Only looking right after I click the 'sort' button:  Any clue? I even tried invoking sort manually but that was not successful.

I've got an NSSplitView with an NSScrollView in the bottom view. The problem is when I collapse, and then re-open (un-collapse) the bottom view, the height of the scroll view is beyond the height of that bottom view so the top part of the scoll view is being clipped. I've got my scroll view and my split view set to autoresize in all directions in IB. Do I need to adjust the height of that scroll view after the un-collapse or am I setting a resizing property wrong, or something else? Below is a before and after image of what the clipping looks like. Before Collapse:  After Collapse and re-open (notice the scroll bar in the bottom view is clipped) 

How do I fix the height of my view after collapsing NSSplitView?

How can I configure a ASP.NET GridView to populate it by an Object DataSource where the object method needs a noticeCode to pass by the C# code? ## StudentControlPanel.aspx.cs ``` protected void Page_Load(object sender, EventArgs e) { string username = (string)Request.QueryString["username"]; Student std = Student.GetStudentByUsername(username); if (std != null) { labName.Text = std.StudentName; labUsername.Text = username; labRollNo.Text = std.RollNo; labRegNo.Text = std.RegNo; Dept dpt = std.Department; if (dpt != null) { labDepartment.Text = dpt.DeptName; } else { labDepartment.Text = "?"; } } /* Student-class has a SessionCode-property */ /* I need to pass this to Notice.GetNoticesBySessionCode()...*/ } ``` ## Notice.cs ``` public class Notice { public static List<Notice> GetNoticesBySessionCode(string sessionCode) { List<Notice> notices = null; /* EcecuteReader()..... */ return notices; } } ```

I find decorator pattern to be most confusing. Please consider the example provided in "Head first design patterns book".  So to get a with double mocha and a whip, you have to write ``` Beverage beverage2 = new DarkRoast(); beverage2 = new Mocha(beverage2); beverage2 = new Mocha(beverage2); beverage2 = new Whip(beverage2); ``` I feel this is unnecessary. Here is my implementation, ``` interface Beverage { int Cost(); } class DarkRoast : Beverage { /* .... */ } class Mocha : Beverage { /* .... */ } class Whip : Beverage { /* .... */ } // here is the changed part class Order { List<Beverage> beverages = new List<Beverage> beverages(); public void AddItem(Beverage b) { beverages.Add(b); } public int Cost() { int cost; foreach(Beverage b in beverages) cost += b.Cost(); } } // use it like Order order = new Order(); order.AddItem(new DarkRoast()); order.AddItem(new Mocha()); order.AddItem(new Mocha()); order.AddItem(new Whip()); int cost = order.Cost(); ``` IMO, both does same. If yes, what is the advantage of using decorator pattern here? Any thoughts?

 I actually have two questions, I found the answer to the second and didn't update the diagram. I'm not actually sure if these are possible, they really stumped me. Given point A and e, the angle of the line A is on relative to the x-axis where 0<=e<360 degrees, how do you calculate the coordinates of B? BA is perpendicular to A's line and 1 unit long. SOLVED: I start by taking the unit vector from a parallel to the x-axis and then I rotate it 90 + e degrees. I'm using [this](https://stackoverflow.com/questions/1211212/how-to-calculate-an-angle-from-three-points) approach. If anyone has any better suggestions, please let me know. SOLVED: I find the dot product of the vector from step 1 and the normalized vector AC. This one should be pretty self-explanatory from the diagram. I need to find the coordinates of C given A, B, the angle of BAC and the distance between A and C. SOLVED: I rotate BA e degrees and then change the magnitude to d. If anyone spots problems with my solutions, please comment.

I need to calculate the 2 angles (yaw and pitch) for a 3D object to face an arbitrary 3D point. These rotations are known as "Euler" rotations simply because after the first rotation, (lets say Z, based on the picture below) the Y axis also rotates with the object. This is the code I'm using but its not working fully. When on the ground plane (Y = 0) the object correctly rotates to face the point, but as soon as I move the point upwards in Y, the rotations don't look correct. ``` // x, y, z represent a fractional value between -[1] and [1] // a "unit vector" of the point I need to rotate towards yaw = Math.atan2( y, x ) pitch = Math.atan2( z, Math.sqrt( x * x + y * y ) ) ``` Do you know how to calculate the 2 Euler angles given a point? --- The picture below shows the way I rotate. These are the angles I need to calculate. (The only difference is I'm rotating the object in the order X,Y,Z and not Z,Y,X) [](https://i.stack.imgur.com/wZXrd.jpg) [](https://i.stack.imgur.com/kK7A0.jpg) --- This is my system. - - -

 Do you know any rounded corners tab like this one that I can download? Or how can I create a tab like that? Do the use of images in the tab menus are required or not? I used the: ``` -moz-border-radius-topleft: 5px; -moz-border-radius-topright: 5px; border-top-left-radius:5px; border-top-right-radius:5px; ``` but it is not perfect. Do you know any helpful links/tutorials about rounded corner tab?

I have a shared runtime package that I am using to support an application that uses packages as a plugin system. I have included several third party units in the shared package to reduce the number of BPLs that have to be distributed. Delphi seems to have some headaches with this set up, occasionally updating only the DCP file in the "shared DCP" area (C:\Users\Public\Documents\RAD Studio\6.0\Dcp on my machine) and not the one in the DCP output directory (as specified in the project options). That isn't my main problem though... My main problem is that Delphi throws up this dialog quite often:  (this is just an example, it happens for other packages I have installed as well) Now, in Delphi 2009, at least when I cancel this dialog (and click yes on the dialog that comes up next), it doesn't change anything. Previous versions would still proceed to munge my dpk file. I currently can't get the damned dialog to stop coming up. The package is set as a runtime package, it does not have any packages "required" (other than the VCL ones). I thought I had it licked a month ago, but it has started coming up again. There are no changes to the DPK file or the DPROJ file. I know why it is doing it... Delphi is trying to keep this package internally consistent with other packages in the IDE, just in case I install it. I would like to stop the IDE doing this. Does anyone have any suggestions? N@

I'm recently working on a tree structure, multiple nodes, multiple and increasable levels, and a print() method. At first, i thought it should be a Composite, i then wrote down some possible design and codes:  ``` $struc = new Node(‘name0’, ‘id0’, ‘desc0’); $node1 = new Node(‘node1’, ‘id1’, ‘desc1’); $node2 = new Node(‘node2’, ‘id2’, ‘desc2’); $node3 = new Node(‘node3’, ‘id3’, ‘desc3’); $leaf1 = new Leaf(‘leaf1’, ‘ld1’, ‘lesc1’); $leaf2 = new Leaf(‘leaf2’, ‘ld2’, ‘lesc2’); $leaf3 = new Leaf(‘leaf3’, ‘ld3’, ‘lesc3’); $leaf4 = new Leaf(‘leaf4’, ‘ld4’, ‘lesc4’); $struc.add($node1); $struc.add($node3); $node1.add($leaf1); $node1.add($leaf2); $node1.add($node2); $node2.add($leaf3); $node3.add($leaf4); ``` Looks good, i think and begin coding, print() method may follow Iterator pattern later. But during coding, i feel is it too complex for these simple nodes? And i have to instantiate a lot of concrete classes (more than 50+, and increasing). I then stopped and thinking a simple similar way by using array: ``` -- Structure Class -- //To be more readable and clear, array here could be //divided to 3 arrays(root/nodes/leafs), then connect //in a similar way Composite does. $struc = array('name0', 'id0', 'desc0', 'children'=>array( array('node1', 'id1', 'desc1', 'children' => array( array('leaf1', 'ld1', 'lesc1'), array('leaf2', 'ld2', 'lesc2'), array('node2', 'id2', 'desc2', 'children'=>array(array('leaf3', 'ld3', 'lesc3')) ) ) ), array('node3', 'id3', 'desc3', 'children' => array(array('leaf4', 'ld4', 'lesc4')) ) ) ); function print($node = $this->struct) { ... if(isset($node['children'])) $this->print($node['children']); ... } ``` The two designs look very similar, now i'm a little confused, what's the value of Composite pattern, am i missed something important of this pattern?

What advantage will Composite pattern bring me over just Array?

In the following code, why isn't the button text initially displayed when ButtonSkin (from com.sun.javafx.scene.control.caspian) is used? In the following code (running WinXP, NetBeans 6.7.1, JavaFX 1.2 , JDK 1.6), when ButtonSkin is used, the button text starts as blank. After the slider is used, te button text is displayed. [googlepages.com](http://onecynic.googlepages.com/withButtonSkin.jpg) to [googlepages.com](http://onecynic.googlepages.com/withButtonSkinAfterAdjust.jpg) If you press the button before moving the slider, the action is triggered, printing "Some action slider 15.0 SliderInt 15". That suggests the information for the button text is present. Yet the button text is not displayed. If the skin isn't set, that is, the code `skin: ButtonSkin { ... }` is commented out, on start-up the result is: [googlepages.com](http://onecynic.googlepages.com/withoutButtonSkin.jpg) If one instead removes the bind in the `text: sliderIntText`, the problem also goes away. However, the button text is no longer updated in sync with the slider movement. Removing the levels of indirection, i.e., just binding to answerSlider.value in the button text makes no change in the start-up issue. Aside: There is a known slider value problem which occurs when the slider min is not 0. I'm not trying to resolve that issue here. ``` package skinbutton; import javafx.stage.Stage; import javafx.scene.Scene; import javafx.scene.text.Text; import javafx.scene.text.Font; import javafx.scene.text.FontWeight; import javafx.scene.control.Button; import com.sun.javafx.scene.control.caspian.*; import javafx.scene.paint.Color; import javafx.scene.control.Slider; var answerSlider = Slider { min: 6 max: 32 value: 15 width: 100 translateX: 75 translateY: 20 }; var sliderIntValue:Integer = bind (java.lang.Math.floor(answerSlider.value)) as Integer ; var sliderIntText = bind "SliderInt {%d sliderIntValue}"; var sceneSlider = Scene{ content: [ answerSlider, Text { font : Font { size: 14 } x: 75 y: 50 content: bind "Slider at {%4.1f answerSlider.value}" } Button { translateX: 75 translateY: 60 skin: ButtonSkin { fill: Color.LIGHTCORAL textFill: Color.BLACK } text: bind sliderIntText width: 95 font: Font.font("SansSerif", FontWeight.BOLD, 14) action: function() { println("Some action slider {%4.1f answerSlider.value} {sliderIntText}"); } } ] }; Stage { title: "Button Skin Issue" width: 250 height: 130 scene: sceneSlider } ```

I have a virtual machine running windows 2003 server running MOSS 2007. This virtual machine is not being run on my dev machine, but on a different machine on the network. I can ping both the host and guest OS from my dev machine. I just need to know, if it is possible, how to configure visual studio 2008 to deploy the web parts/projects/etc to the remote VM when I do this:  Any input will be greatly appreciated! Thanks.

Is it possible to deploy a Web Part from Visual Studio 2008 to a (virtual) MOSS 2007 server on my network?
