Let's say I have a class that implements the interface. Something like this:  uses some unmanaged resources, hence the method from releases those resources. should be used like this: ``` using ( MyClass myClass = new MyClass() ) { myClass.DoSomething(); } ``` --- Now, I want to implement a method that calls asynchronously. I add a new method to :  Now, from the client side, should be used like this: ``` using ( MyClass myClass = new MyClass() ) { myClass.AsyncDoSomething(); } ``` However, if I don't do anything else, this could fail as the object might be disposed before is called (and throw an unexpected ). So, the call to the method (either implicit or explicit) should be delayed until the asynchronous call to is done. I think the code in the method should be executed . I'd like to know which could be the best way to accomplish this. Thanks. [Dispose pattern](http://msdn.microsoft.com/en-us/library/fs2xkftw(VS.80).aspx) --- Thank you so much for your responses. I appreciate your effort. As [chakrit](https://stackoverflow.com/users/3055/chakrit) [has commented](https://stackoverflow.com/questions/400130/how-to-dispose-asynchronously#400165), I need that . Ideally, something like this should work fine: ``` using ( MyClass myClass = new MyClass() ) { myClass.AsyncDoSomething(); myClass.AsyncDoSomething(); } ``` I'll study the counting semaphore, it seems what I'm looking for. It could also be a design problem. If I find it convenient, I will share with you some bits of the real case and what really does.

Short of inserting a try/catch block in each worker thread method, is there a way to deal with unhandled, non-ui thread, exceptions in Windows Forms? `Thread.GetDomain().UnhandledException` works great for catching the error, but by then it's too late to do anything about it (besides log it). After control passes out of your `UnhandledException` handler the application will terminate. The best you can hope for is a generic Windows error that looks this:  All my research indicates that you insert a try/catch block in the worker thread method, but I wanted to put this out there in case anyone had a different take. Thanks.

I'm trying to do that for a couple of days now, and after reading tons of messages of people trying to do that too, I'm still unable to have a fully working `UITextField` in some of my `UITableViewCells`, just like in this example:  Either I have the form working but the text is not visible (although I set its color to blue), the keyboard goes on the field when I click on it and I haven't been able to correctly implement the keyboard events. I tried with a bunch of examples from Apple (mainly `UICatalog`, where there is a kinda similar control) but it's still not working correctly. Can somebody help me (and all the people trying to realize this control) and post a simple implementation of a `UITextField` in a `UITableViewCell`, that works fine?

I would like to clarify the differences between by value and by reference. I drew a picture:  So, for passing by value, a copy of an identical object is created with a different reference, and the local variable is assigned the new reference, so to point to the new copy How should I understand the following? > If the function modifies that value, the modifications appear also within the scope of the calling function for both passing by value and by reference

### Boring introduction: In my workplace, we have a very old WinForms product (in market since 1994, and still running on VB3). It has three very different versions, each of them goes to one client. The clients pass it on to their users, some of which are shared. The versions can live side-by-side. Five years ago, we rewrote one of those versions in C#.Net. Two years later, another version (let's call it version M) was rewritten, and two years after that, it was time for the last remaining version (let's call it version C) to be converted. We've been working for one year, and are going to production this week. During the conversions, it has been decided not to convert anything that was sold as an external module; these were built in VB6, and they used several controls from [BeCubed](http://www.becubed.com/index.htm) and [FarPoint](http://www.fpoint.com/). There are two such modules in version M, and three modules in version C. Each module has it's own MSI installer, which is run quietly by the main product's installer. ### The bug During production, we found a bug: when version C in installed on a fresh computer, then version M is installed, we get a message as soon as an external module is opened in version C:  After clicking Ok, the module works. Also, this doesn't happen when they are installed in any other order and both modules in version M work perfectly. ### Other details - - - --- Does anyone know what could cause such an error, what could be a possible solution?

I'm a bit confused with this one. I have a Dataset with a BackupDate and a BackupTime as well as a BackupType. The BackupDate is comprised of 12 characters from the left of a datetime string within a table. The BackupTime is comprised of 8 characters from the right of that same datetime string. So for example: BackupDate would be 'December 12 2008' and the BackupTime would be '12:53PM.' I have added an XY-scatter chart to the report. I've added a 'series' value for the BackupType (so one can distinguish between a Full/Incr/Log backup). I've added a category value of BackupDate and set the Scale for the X-axis from the Min of BackupDate to the Max of BackupDate. I've then added an item to the Values with the Y variable set to BackupTime and the X variable set to BackupDate. The interval for the Y-axis is 12:00AM to 11:59PM and the formatting for the labels is 'hh:mmtt'. The BackupTime matches the format of the Y-axis. The BackupDate matches the format of the X-axis. 10 entries are retrieved by my Dataset and the Legend is properly populated by the BackupType field. No points are being plotted on the graph and no markers/pointers are shown if they are enabled. There should be a point on the graph for every point in time of each day there is a backup of a specific type. Am I missing something? Does anyone know of a good tutorial dealing specifically with XY-scatter graphs and using them in a way I intend? I am using the 2005 version of SSRS rather than the 2008 version. Screenshot of what my chart currently looks like:  In case it could be dataset related: ``` SELECT TOP (10) backup_type, LTRIM(RTRIM(LEFT(backup_finish_date, 12))) AS BackupDate, LTRIM(RTRIM(RIGHT(backup_finish_date, 8))) AS BackupTime FROM DBARepository.Backup_History ``` As requested, here are the results of this query. There is a Where clause to constrain the results to a specific database of a specific server that was not included in the above SQL Query.

From the outset, collision detection feels like it is an O(n^2) problem. You have a bunch of objects and you need to check if each object is colliding with any of the other objects. However, I know that it is wildly ineffecient to check each object against all the other objects. Why do a relatively expensive collision check between two balls if they aren't even close to eachother? Here is example of my simple program I'm working on:  If you have 1000 balls then if you went with the naive collision detection you would have 1000^2 collection checks (a million)! This collision checking has quickly become the bottleneck in my application. I to implement some broad phase pruning. What techniques should be used to prune collision checks when working with 2d - circular objects? I've read about QuadTrees, BSP, spatial hashing, etc but it is difficult to sort out what method is most appropriate to this use case. Does anyone have any knowledge about what might work best?

In interface builder i've created a UITextfield within a subclass of a UITableViewCell. The default font is just too small. If I make it bigger in interface builder it looks a bit ugly. Not as crisply rendered. I'd like a font similar to that used in the addressBook application when you edit a contact. The text their is bigger than the default and display nice. Anyone got a good font/style/size? And I should set this in IB right? The UITextfield class states: @property(nonatomic,retain) UIFont *font; // default is nil. use system font 12 pt Does this mean they only want you to use size 12? Thanks!

I've been developing a very large LOB app using my flavor of M-V-VM which I call M-V-MC (Model-View-ModelController), which is a kind of a combination between M-V-C and M-V-VM. I had posted [this answer](https://stackoverflow.com/questions/322612/what-are-the-most-common-mistakes-made-in-wpf-development#322679) regarding how views get instantiated in M-V-VM to the question "[what-are-the-most-common-mistakes-made-in-wpf-development](https://stackoverflow.com/questions/322612/what-are-the-most-common-mistakes-made-in-wpf-development)". [Sam](https://stackoverflow.com/users/7021/sam) made the following comment regarding my answer: > This creates a follow-up-question: how do you create the views? I use RelayCommands to bind actions from the view to the ViewModel, so the view does not even know an action has fired, does not know he should open a new view. Solution: create an event in the VM for the View to subscribe to? When I originally started M-V-VM development I had this notion that EVERYTHING should live in the ViewModel, and have studied a lot of examples from guys like [Josh Smith](http://joshsmithonwpf.wordpress.com/) and [Karl Shifflett](http://karlshifflett.wordpress.com/). However I have yet to come up with a good example of when a command needs to live in the ViewModel. For instance, let's say I have a ListView that displays Customers, and a button that I click to allow me to edit the currently selected customer. The ListView (View) is bound to a CustomerVM (ViewModel). Clicking the button fires the EditCustomerCommand which opens a popup window which allows me to edit all the properties of the CustomerVM. Where does this EditCustomerCommand live? If it involves opening a window, (UI functionality), shouldn't it be defined in the code-behind of the view?  Does anyone have any examples of when I should define a command in the View versus the ViewModel? [Matthew Wright](https://stackoverflow.com/users/47006/matthew-wright) states below: > New and delete from a list would be good examples. In those cases, a blank record is added or the current record is deleted by the ViewModel. Any action taken by the view should be in response to those events occurring. So if I click the new button, what happens? A new instance of the CustomerVM is created by the Parent ViewModel and added to it's collection right? So how then would my editing screen get opened? The view should create a new instance of the Customer ViewModel, and pass it in to the ParentVM.Add(newlyCreatedVM) method right? Let's say I delete a customer record via the DeleteCommand living on the VM. the VM calls into the business layer and tries to delete the record. It can't so it returns a message to the VM. I want to display this message in dialogbox. How does the view get the message out of the command action?

I am trying to use Windows Workflow and have a model that looks similar to the image in the link below:  After each of the Send Activities (`GetSomthing`, `GetSomthingElse`, `GetSomeMoreStuff`) the same custom activity is being called (`LogSomthingBadHappened`). While it might not look so bad in this picture in my real model the custom activity is a SequenceActivty, has quite a few nodes, and when its repeated 3 times starts to make the workflow look very ugly. I would like to do something like this:  Can the `IfElse` branches be merged like this? Should I be using a State Machine work flow instead (haven't figured these out yet)?

I have to code a simple control in .Net that draws geometry that looks like following image and the geometry doesn't get any more complex than shown in this image, i.e. it will be a few filled polygons and some dashed lines. This is not a static image however, that is drawn once and forgotten. The dimensions of the geometry can be changed by the user which will have to be reflected in the drawing by updating it.  My senior says I should use WPF for drawing. My question is whether WPF is overkill for this kind of work and will System.Drawing suffice?

How hard would it be to take an image of an object (in this case of a predefined object), and develop an algorithm to cut just that object out of a photo with a background of varying complexity. Further to this, a photo's object (say a house, car, dog - but always of one type) would need to be transformed into a 3d render. I know there are 3d rendering engines available (at a cost, free, or with some clause), but for this to work the object (subject) would need to be measured in all sorts of ways - e.g. if this is a person, we need to measure height, the curvature of the shoulder, radius of the face, length of each finger, etc. What would the feasibility of solving this problem be? Anyone know any good links specialing in this research area? I've seen open source solutions to this problem which leaves me with the question of the ease of measuring the object while tracing around it to crop it out. Thanks --- Essentially I want to take a 2d image (typical image:which is easier than a complex photo containing multiple objects, etc.)  , But effectively I want to turn that into a 3d image, so wouldn't what I want to do involve building a 3d rendering/modelling engine? Furthermore, that link I have provided goes into 3ds max, with a few properties set, and a render is made.

I'm using [LaTeX](http://www.latex-project.org/)'s "[listings](http://en.wikibooks.org/wiki/LaTeX/Packages/Listings)" package to format source code. Unfortunately I get curly quotes instead of straight quotes. Since the curly quotes don't always point in the right direction, it looks bad. How can I get straight quotes instead? I'd prefer not to change or filter the source code itself. Filtering the code to properly change " to `` or '' would work, but this is easier done than said with multiple quotes on a line, or quotes spanning multiple lines. Or you could use symbol or a host of other things. But I'd really like to keep the source unchanged. Example LaTeX: ``` \documentclass{article} \usepackage{listings} \begin{document} \begin{lstlisting} Fahrenheit=input("What is the Fahrenheit temperature?") Celsius=(5.0/9.0)*(Fahrenheit-32) print"The temperature is",Celsius,"degrees Celsius" \end{lstlisting} \end{document} ``` Example output (using [Miktex](http://miktex.org/) on windows):  ([Direct link to image of incorrect output](https://farm4.static.flickr.com/3450/3186136899_306b443283_o.png))

I am using Django's RSS capabilities to build an RSS feed. The `<description>` of the RSS feed items contains HTML markup. Currently, I am just injecting the HTML markup into the feed using the following template: ``` {{ obj.post }} ``` Django, of course, translates special characters (`<`, `>`, `&`, etc.) to their respective HTML entities. I know I could just output the HTML and wrap all the HTML code in `<![CDATA[...]]>` sections. [This page](http://cyber.law.harvard.edu/rss/encodingDescriptions.html) says that either method is acceptable. If that's true, is there a good reason to pick one method over the other? And if I use example #2, is there a filter for Django to automatically wrap the HTML text in CDATA tags, or should I just change my template to: ``` <![CDATA[ {{ obj.post|safe }} ]]> ``` --- # Edit It seems that Django autoescapes special characters in RSS feeds (or any XML for that matter) no matter what, regardless of whether you pass it through the `safe` filter or not (the issue is discussed in [this ticket](http://code.djangoproject.com/ticket/6533)). However, general answers are welcome.

Is there a way with CSS to wrap text on sides of an element (an image for example). I am trying to have an image positioned in the middle of a paragraph and would like text to flow over it.

This is the code I have that HTML Validator is giving me an error on: ``` <input type="text" id="search" name="keywords" /> <input type="submit" value="Search" name="Submit" /> ``` ([full size](https://i.stack.imgur.com/1B67V.png)):  This is the error message I am receiving: > The mentioned element is not allowed to appear in the context in which you've placed it; the other mentioned elements are the only ones that are both allowed there and can contain the element mentioned. This might mean that you need a containing element, or possibly that you've forgotten to close a previous element.There are 2 types of elements in the body of a HTML file, inline and block elements. One possible cause for this message is that you have attempted to put a block-level element (such as "<p>" or "<table>") inside an inline element (such as "<a>", "<span>", or "<font>").In the following sample, the <font> tag is an inline tag which can only contain other inline tags. But the <p> tag is a block tag. So a <p> tag can not be contained in a <font> tag. This is the block of html that it is from: ``` <li> <form method="post" action="http://site.com/" > <div class='hiddenFields'> <input type="hidden" name="ACT" value="19" /> <input type="hidden" name="XID" value="90ee0994104d8ba87b6ef9b43e998fc8c89e0d9f" /> <input type="hidden" name="RP" value="search/results" /> <input type="hidden" name="NRP" value="" /> <input type="hidden" name="RES" value="" /> <input type="hidden" name="status" value="" /> <input type="hidden" name="weblog" value="forms|alumni_distinguished|housing_faq|international_faq" /> <input type="hidden" name="search_in" value="everywhere" /> <input type="hidden" name="where" value="all" /> <input type="hidden" name="site_id" value="1" /> </div> <input type="text" id="search" name="keywords" /> <input type="submit" value="Search" name="Submit" /> </form> </li> ```

I have the following text from an academic course I took a while ago about inorder traversal (they also call it pancaking) of a (not BST): > Draw a line around the outside of the tree. Start to the left of the root, and go around the outside of the tree, to end up to the right of the root. Stay as close to the tree as possible, but do not cross the tree. (Think of the tree — its branches and nodes — as a solid barrier.) The order of the nodes is the order in which this line passes underneath them. If you are unsure as to when you go “underneath” a node, remember that a node “to the left” always comes first. Here's the example used (slightly different tree from below)  However when I do a search on google, I get a conflicting definition. For example the [wikipedia example](http://en.wikipedia.org/wiki/Tree_traversal):  > Inorder traversal sequence: A, B, C, D, E, F, G, H, I (leftchild,rootnode,right node) But according to (my understanding of) definition #1, this should be > A, B, D, C, E, F, G, I, H They might be both describing different traversal methods, but happen to be using the same name. I'm having trouble believing the peer-reviewed academic text is wrong, but can't be certain.

I want to show an image from an URL with a certain width and height even if it has a different size ratio. So I want to resize (maintaining the ratio) and then cut the image to the size I want. I can resize with html `img` property and I can cut with `background-image`. How can I do both? Example: This image:  Has the size `800x600` pixels and I want to show like an image of `200x100` pixels With `img` I can resize the image `200x150px`: ``` <img style="width: 200px; height: 150px;" src="http://i.stack.imgur.com/wPh0S.jpg"> ``` That gives me this: ``` <img style="width: 200px; height: 150px;" src="https://i.stack.imgur.com/wPh0S.jpg"> ``` And with `background-image` I can cut the image `200x100` pixels. ``` <div style="background-image: url('https://i.stack.imgur.com/wPh0S.jpg'); width:200px; height:100px; background-position:center;">&nbsp;</div> ``` Gives me: ``` <div style="background-image:url('https://i.stack.imgur.com/wPh0S.jpg'); width:200px; height:100px; background-position:center;">&nbsp;</div> ``` How can I do both? Resize the image and then cut it the size I want?

I'm using Linq-to-SQL with a SQL Server backend (of course) as an ORM for a project. I need to get the result set from a stored procedure that returns from a dynamically-created table. Here's what the proc looks like: ``` CREATE procedure [RetailAdmin].[TitleSearch] ( @isbn varchar(50), @author varchar(50), @title varchar(50)) as declare @L_isbn varchar(50) declare @l_author varchar(50) declare @l_title varchar(50) declare @sql nvarchar(4000) set @L_isbn = rtrim(ltrim(@isbn)) set @l_author = rtrim(ltrim(@author)) set @l_title = rtrim(ltrim(@title)) CREATE TABLE #mytemp( [storeid] int not NULL, [Author] [varchar](100) NULL, [Title] [varchar](400) NULL, [ISBN] [varchar](50) NULL, [Imprint] [varchar](255) NULL, [Edition] [varchar](255) NULL, [Copyright] [varchar](100) NULL, [stockonhand] [int] NULL ) set @sql = 'select a.storeid, Author,Title, thirteendigitisbn ISBN, Imprint,Edition,Copyright ,b.stockonhand from ods.items a join ods.inventory b on a.itemkey = b.itemkey where b.stockonhand <> 0 ' if len(@l_author) > 0 set @sql = @sql + ' and author like ''%'+@L_author+'%''' if len(@l_title) > 0 set @sql = @sql + ' and title like ''%'+@l_title+'%''' if len(@L_isbn) > 0 set @sql = @sql + ' and thirteendigitisbn like ''%'+@L_isbn+'%''' print @sql if len(@l_author) <> 0 or len(@l_title) <> 0 or len(@L_isbn) <> 0 begin insert into #mytemp EXECUTE sp_executesql @sql end select * from #mytemp drop table #mytemp ``` I didn't write this procedure, but may be able to influence a change if there's a really serious problem. My present problem is that when I add this procedure to my model, the designer generates this function: ``` [Function(Name="RetailAdmin.TitleSearch")] public int TitleSearch([Parameter(DbType="VarChar(50)")] string isbn, [Parameter(DbType="VarChar(50)")] string author, [Parameter(DbType="VarChar(50)")] string title) { IExecuteResult result = this.ExecuteMethodCall(this, ((MethodInfo)(MethodInfo.GetCurrentMethod())), isbn, author, title); return ((int)(result.ReturnValue)); } ``` which doesn't look anything like the result set I get when I run the proc manually:  Can anybody tell me what's going wrong here? This is basically the same problem as [this question](https://stackoverflow.com/questions/404186/problem-with-the-return-type-of-a-stored-procedure) but due to the poor phrasing from the OP it was never really answered. --- Thanks Marc for your reply. I will see about making the changes you suggested. The problem was the temp table. Linq to Sql just doesn't know what to do with them. This was particularly difficult to diagnose, because Visual Studio caches information about stored procs, so when it initially failed to find a result set it set the return as a default integer type and didn't update when I made changes to the stored proc. Getting VS to recognize a change requires you to: - - - - - You might not have to do every one of those steps, but that's what worked for me. What you need to do, if you must use a temp table, is to create a barebones proc that simply returns the correct schema, and then alter it to do what you want after you've imported it into the OR Designer.

I want two tables to have the same height. If the left table contain longer text than the right table I want it to be as long as the left table. This is how it looks now:  I can't set the height because that would limit how much text you can write... This is how I want it:  Code: ``` <table cellspacing="0" width="30%" align="left" class="rowA"> <tr> <td> Sed ut perspiciatis unde omnis iste natus error sit voluptatem accusantium doloremque laudantium, totam rem aperiam, eaque ipsa quae ab illo inventore veritatis et quasi architecto beatae vitae dicta sunt explicabo. "Sed ut perspiciatis unde omnis iste natus error sit voluptatem accusantium doloremque laudantium, totam rem aperiam, eaque ipsa quae ab illo inventore veritatis et quasi architecto beatae vitae dicta sunt explicabo. </td> </tr> </table> <table cellspacing="0" width="70%" align="right" class="rowB"> <tr> <td> Lorem ipsum dolor sit amet, consectetur adipisicing elit, sed do eiusmod tempor incididunt ut labore et dolore magna aliqua.

After the previous question "What are the important rules in Object Model Design", now I want to ask this: Suppose that we have this schematic object model:  So, each object could have lots of properties due to the set of implemented Interfaces, and then become relatively heavy object. Creating all the possible -and of course reasonable- object can be a way for solving this problem , but I have a large number of interfaces by now, that make it difficult. I wonder if there is a way to have dynamic properties, something like the following dialog to allow the end user to select available functionalities for his/hers new object.

I know this seams a trivial question, but how can I disable the annoying JavaScript error messages? I am inserting data into an unfinished web application and I keep getting about 30 errors for every form I submit. It's driving me crazy. I'm using IE7. Please note that I already tried "Internet options - Advanced - Browsing", disabled script debugging for IE and other and unchecked the "display a notification for every script error". All I got was a different error message, but I still have to close a LOT of alert messages. I think I am going insane. EDIT: Before and after Image(url omitted to protect the innocents):  I don't have access to the code, I am just inserting data, the application is still being built and the JavaScript is generated from codebehind. There is absolutely nothing I can do to remove this errors.

Can anyone suggest a suitable way of figuring out a pieces allowable moves on a grid similar to the one in the image below.  Assuming piece1 is at position a1 and piece2 is at position c3, how can I figure out which grid squares are allowable moves if piece1 can move (say) 3 squares and piece2 can move 2? I've spent way too long developing text based MUDS it seems, I simply can't get my brain to take the next step into how to visualise potential movement even in the most simple of situations. If it matters, I'm trying to do this in javascript, but to be perfectly honest I think my failure here is a failure to conceptualise properly - not a failure in language comprehension. It's sloppy and it only works for one item placed on the board so far, but at least the `check_allowable_moves()` function works for this initial run. For those of you wondering why the hell I'm creating those weird alphanumeric objects rather than just using numeric x axis and y axis - it's because an id in HTML can't start with a number. In fact pretending I use numbers to start ids helped a great deal in making sense of the functionality and concepts described by the fantastic answers I got. ``` <!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Strict//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-strict.dtd"> <html xmlns="http://www.w3.org/1999/xhtml" xml:lang="en" lang="en"> <head> <meta http-equiv="Content-Type" content="application/xhtml+xml;utf-8"/> <title>Test page</title> <style> #chessboard { clear: both; border:solid 1px black; height: 656px; width:656px; /*width = 8*40 + 16 for border*/ } #chessboard .row { overflow: auto; clear: both; } #chessboard .row span { display: block; height: 80px; width: 80px; float: left; border:solid 1px black; } .allowable { background: blue; } </style> <script type="text/javascript" src="http://www.google.com/jsapi"></script> <script type="text/javascript"> google.load("jquery", "1.2.6"); google.load("jqueryui", "1.5.3"); </script> <script type="text/javascript"> $(document).ready(function() { (function() { var global = this; global.Map = function(container) { function render_board() { var max_rows = 8; var cols = new Array('a','b', 'c', 'd', 'e', 'f', 'g', 'h'); var jqMap = $('<div />'); jqMap.attr('id', 'chessboard'); var x=0; for(x; x<max_rows; x++) { var jqRow = $('<span />'); jqRow.addClass('row'); var i=0; for(i; i<cols.length; i++) { var jqCol = $('<span />'); jqCol.attr('id', cols[i]+(x+1)); jqCol.addClass(cols[i]); jqRow.append(jqCol); } jqMap.append(jqRow); } $('#'+container).append(jqMap); } function add_piece(where, id) { var jqPiece = $('<div>MY PIECE'+id+'</div>'); var jqWhere = $('#'+where); jqPiece.attr('id', 'piece-'+id); jqPiece.addClass('army'); jqPiece.draggable({cursor: 'move', grid:[82, 82], containment: '#chessboard', revert: 'invalid', stop: function(ev, ui) { //console.log(ev.target.id); } }); jqWhere.append(jqPiece); check_allowable_moves(where); } function check_allowable_moves(location) { var x_axis = { 'a':1,'b':2, 'c':3, 'd':4, 'e':5, 'f':6, 'g':7, 'h':8 }; var x_axis_alpha = { 1:'a',2:'b', 3:'c', 4:'d', 5:'e', 6:'f', 7:'g', 8:'h' }; $('.allowable').droppable("destroy"); $('.allowable').removeClass('allowable'); //get the x,y values of the piece just placed var x = parseInt(x_axis[location[0]], 10); var y = parseInt(location[1], 10); var x_min = x-2; var y_min = y-2; for(x_min; x_min<=x+2; x_min++) { for(y_min; y_min<=y+2; y_min++) { var jqCell = $('#'+x_axis_alpha[x_min]+y_min) jqCell.addClass('allowable'); jqCell.droppable({ accept: '.army', drop: function(ev, ui) { //console.log(ev, ui, $(this)); //handle_drop(ev, ui, $(this)); check_allowable_moves($(this).attr('id')); } }); } y_min = parseFloat(y)-2; } } render_board(); add_piece('d5', '2'); } })(); var map = new Map('content'); }); </script> </head> <body id="debug"> <div id="page"> <div id="content"> </div> </div><!-- end page --> </body> </html> ```

I'm currently looking at different solutions getting 2 dimensional mathematical formulas into webpages. I think that the wikipedia solution (generating png images from LaTeX sourcecode) is good enough until we get support for MathML in webbrowsers. I suddenly realized that it might be possible to create a [Google Charts API](http://code.google.com/apis/chart/) equivalent for mathformulas. Has this already been done? Is it even possible due to the strange characters involved in LaTeX-code? I would like to hit an url like latex2png.org/api/?eq="E = mc^2" and get the following response:  Thanks for the answers sofar. However, I am already aware of several tools to generate png images from latex source code (both online and from my commandline), but what I was looking for was a simple way to get the image via an Http GET request. Perhaps such a service does not exist.

I'm showing a popup menu to select some values in a QTableWidget. The lowest item is a "Modify list" entry, when I select it a new window should automatically appear and the QComboBox should vanish and the cell return to a Qt::DisplayRole state. Now Qt has all those nice API-calls like `QTableWidget.edit()` and `QTableWidget.editItem()`, what I'm really looking for is a `QTableWidget.endEditing()`, preferably without specifying the index of the cell, though I could get that using this call: ``` table.currentIndex() ``` … but I don't know if I can guarantee that the current cell is the cell being edited at all times. Is there an API to close those kind of editors?

HI all. I am working on some code to send/receive SMS messages through Zeep Mobile ([http://zeepmobile.com/developers/](http://zeepmobile.com/developers/)). I have looked at their google groups and even contacted their support but they've not been very good at communicating back and I am really flying blind now. I have to get integrated with them (work has required it) and I'm not sure why my code is not working. So, I'm wondering if anyone out there has any C# .Net code that they won't mind sharing so that I may integrate that into my app. Of course, this is all dependent on whether you have experience with Zeep or not. If you want me post my code, I can do that too. Let me know.

Can anybody please explain how this could possibly happen? I am completely aware of programming with thread safety in mind and as you can see I am catering for UI updates via a form InvokeRequired check here, everything has been working fine and no changes to break this that I am aware, and now suddenly just as I'm programming other parts of the application (perhaps added to this method at one stage? I just can't remember) I intimitently, receive this error:  Firstly, if InvokeRequired = true, that should mean BeginInvoke() executed, the method is [queued] to be re-called and InvokeRequired should equal false? I should not receive this exception as it should be catered for? Hope to hear from some multi threading guru's :) Graham

In Sharepoint document library, when we create a new document library, the default view is 'All Document'. This one:  We can make a custom view from (at the upper right corner of document library view). I created a new standard view and named it 'Chromed View'. I edited it, then I saw that this view only applied on current document library:  The other document libraries cannot use this view. I develop a system that triggers document library creation from CRM (the document library's view from CRM Iframe is using that chromed view). The creation itself went well, I can create document library using Sharepoint web services. But I still cannot apply a custom view automatically for that newly created doc lib. My question is, can we make a view that is global (not in one document library only) so that we can use that global view for any document library. Thanks b4 for any opinion :)

How can I re-direct the user to the standard SharePoint "access denied" page, similar to the image below? Currently, I am throwing an UnauthorizedAccessException, but this error message is not as elegant as SP message. ``` throw new UnauthorizedAccessException("User does not have permission to access this list"); ``` Any help will be highly appreciated.

 I am using the autocomplete YUI feature. However, as you can see I am having trouble aligning the suggestion drop down with the text input when I put a label in front of the text input. I am following [the example here](http://developer.yahoo.com/yui/examples/autocomplete/ac_basic_array_clean.html) exactly except for this snippet of code where I simply replace the H3 with a label element in the form: ``` <div id="myAutoComplete"> <label>Enter a state:</label> <input id="myInput" type="text"> <div id="myContainer"></div> </div> <script type="text/javascript" src="http://developer.yahoo.com/yui/examples/autocomplete/assets/js/data.js"></script> ``` (I also had to change the data.js path from a relative to absolute path.) What is the best way to have the suggestion drop down to line up with the text input? I would like a solution that works on all popular modern browsers (FF3, Safari, Chrome, IE), plus IE6.

I have a sign-up form in my application with several UITextFields. In order to speed up the process I would like to add a next and previous button to a toolbar pinned above the keyboard and allow the user to "tab" between the fields using these buttons. I know I can navigate through the subviews collection on my view, but I was wondering if there was a cleaner way to do this? This functionality is implemented in safari as seen in the following screenshot:

I'm using the excellent JQuery UI to do a "mapping" so the user can "map" persons from one program to persons from other program. using this simple JQuery: ``` $(document).ready(function() { $("div .draggable").draggable({ revert: 'valid', snap: false }); $("div .droppable").droppable({ hoverClass: 'ui-state-hover', helper: 'clone', cursor: 'move', drop: function(event, ui) { $(this) .addClass('ui-state-highlight') .find("img") .removeAttr("src") .attr("src", "_assets/img/icons/check-user-48x48.png"); $(this).droppable('disable'); $(ui.draggable) .addClass('ui-state-highlight') .find("img") .removeAttr("src") .attr("src", "_assets/img/icons/check-user-48x48.png"); $(ui.draggable).draggable('disable'); } }); $("div .droppable").bind("dblclick", function() { $(this) .removeClass('ui-state-highlight') .find("img") .removeAttr("src") .attr("src", "_assets/img/icons/user-48x48.png"); $(this).droppable('enable'); EnableSource($(this)); }); }); ``` I get to this:  was (if possible) create a line between and so it makes the connection between them clear. I can always do it with numbers inside the boxes, but I really wanted to know how to do this using the lines. .

I have HTML markup to deal with that consists of multiple tables nested inside another table. I would like the "inner tables" to all be the same width. I would also like all of the "inner tables" to be no wider than the width of the widest "inner table" in its natural state. I do want to simply set the width of all the tables to some fixed percentage, as I do not know in advance what the width of the widest "inner table" should be until the HTML page is actually generated.  [https://en.wikipedia.org/wiki/File:Erasene-screen001.png](https://en.wikipedia.org/wiki/File:Erasene-screen001.png) I want all tables to be the same width as inner-table-zero. Currently, none of the tables have an assigned width, and that's the way I like it, because I want all inner tables to naturally choose the width of whichever table is widest by default. Is there any CSS or JQuery or Javascript trick anyone knows that will obtain this desired styling? I'm about to delete this question because people seem to want to downvote me for not having a good reason for not wanting 100%. I have a good reason ... I also do not know until runtime table will be the "outermost" table (this is a recursively-generated structure of potentially unlimited depth).

I'm probably thinking about this all wrong but I have the following db tables:  When I run the EF Wizard in VS2008 I get the following model:  You'll notice that in the EF model shows that the Entity has no field for EntityTypeID or EntityStatusId. Instead it shows it as a navigation property, so the field appears to not be addressable when I instantiate an Entity (pardon the terminology confusion: Entity is a Table/Class in my name space not in the EF namespace). How can I assign an EntityTypeID and StatusTypeID when instantiating an Entity?

When you have a table with a Geometry type field (or Geography), you can call the `Reduce()` function to have the shapes reduced in number of vertices. Works very nicely. However, when sevral of the polygons are adjacent (they share parts of their borders), the reduced polygons do not necessarily do so. ## Example The SQL batch: ``` CREATE TABLE #Shapes ( shape geometry, naam varchar(50) ) -- exact: insert into #Shapes (naam, shape) VALUES ('Area A',Geometry::STGeomFromText('POLYGON ((52.084744368912652 5.1304192959796637, 52.085234231548384

First the unreduced set:  Then the reduced set:  These shapes are much simpler and they do have the rough shape correct, but what I would want is to have the border-parts still shared. So they have to be reduced together, in a way. I think you have to break them up into polylines first (from edge to edge), then Reduce the lines and then reassembling them to polygons again. I have no idea how to do this in T-SQL though. Any ideas? I've accepted alphadaogg's answer. Both current answers weren't entirely covincing to me, but alphadogg has certainly put in the most effort and I really appreciate any sharing of thoughts. So the bounty goes to him. I will follow-up with a self-answer later if I find a satisfying method. : I e-mailed with Isaac Kunen, Program Manager on the SqlServer Geo team. His helpfull response is below: > Your problem is not at all rare, but it isn't something we directly support: it's an operation that requires knowledge of the topology of your figures, and we don't have anything like this built in. Essentially, you don't want to store separate polygons for each neighborhood. Rather, you want to store curves representing portions of boundaries, and reuse these boundaries for multiple polygons. When you generalize, you generalize the shared boundary, and all dependent polygons are affected.You could build this yourself---as the posters in the thread you cite hint---but it may be real effort to do so.I don't know the third-party software you're using, but this is the other option. If you don't want a full-fledged GIS, you could use a package like the FME from Safe Software ([http://www.safe.com](http://www.safe.com)). The FME doesn't do general-purpose topology, but I believe it has enough functionality to do what you're looking for. See: [http://www.safe.com/products/desktop/under-the-hood.php#3b](http://www.safe.com/products/desktop/under-the-hood.php#3b).I hope this helps.Cheers,-Isaac

I've inserted an image below showing were I currently stand (css version) and where I want to be (tabled based version).

I'm trying to make a little gallery of some school works I've done in my animation class. I want to put 3 images on each line and they are all in divs because I did onion skin wrapping for a dropshadow on them. Unfortunately this makes them all just stick together in two lines across the page. But I want them specifically formatted so I tried to wrap a div of 480px wide around each set of 3. In IE this works great and it looks perfect. However in firefox it does this  I can't figure out why it is putting that one left aligned on the second line and therefore screwing up the order of the rest. Here's my code: ``` <!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd"> <html xmlns="http://www.w3.org/1999/xhtml"> <head> <meta http-equiv="Content-Type" content="text/html; charset=utf-8" /> <title>Ryan Merl's Portfolio</title> <style type='text/css'> * { padding: 0px; margin: 0px; font-family:Verdana, Arial, Helvetica, sans-serif; font-size: 11px; } body { background-color:#333333; background-image: url('images/head.png'); background-repeat: repeat-x; } a { color:#333333; text-decoration: none; } a:hover { color:#000000; text-decoration:underline; } div.main { width: 800px; background-color:#FFFFFF; margin-top: 10px; color: #000000; height: 1000px; margin-bottom: 10px; } img.thumb { } .wrap1, .wrap2, .wrap3 { display:inline-table; /* \*/display:block;/**/ } .wrap1 { float:left; background:url('images/shadow.gif') right bottom no-repeat; } .wrap2 { background:url('images/corner_bl.gif') left bottom no-repeat; } .wrap3 { padding:0 4px 4px 0; background:url('images/corner_tr.gif' ) right top no-repeat; } </style> <link rel="stylesheet" type="text/css" href="doc/css/style.css" /> <script type="text/javascript" src="src/adapter/shadowbox-base.js"></script> <script type="text/javascript" src="src/shadowbox.js"></script> <script type="text/javascript" src="glossy.js"></script> <script type="text/javascript"> Shadowbox.loadSkin('classic', 'src/skin'); Shadowbox.loadLanguage('en', 'src/lang'); Shadowbox.loadPlayer(['flv', 'html','img', 'swf'], 'src/player'); window.onload = function(){ Shadowbox.init(); }; </script> </head> <body> <center><div class='main'> <img src='images/theantistudio.png' /><br /><br /> <img src='images/gallery.png' /><br /> <div style='text-align:center;width:480px;'> <div class="wrap1"> <div class="wrap2"> <div class="wrap3"> <a href='video/rmerl_particle_fire.flv' rel='shadowbox'><img class='thumb' src='thumbs/thumb_fire.png' /></a> </div> </div> </div> <div class="wrap1"> <div class="wrap2"> <div class="wrap3"> <a href='video/rmerl_firework.flv' rel='shadowbox'><img class='thumb' src='thumbs/thumb_firework.png' /></a> </div> </div> </div> <div class="wrap1"> <div class="wrap2"> <div class="wrap3"> <a href='video/rmerl_fountain.flv' rel='shadowbox'><img class='thumb' src='thumbs/thumb_fountain.png' /></a> </div> </div> </div> </div> <br /> <div style='text-align:center;width:480px;'> <div class="wrap1"> <div class="wrap2"> <div class="wrap3"> <a href='video/rmerl_logo.flv' rel='shadowbox'><img class='thumb' src= 'thumbs/thumb_logo.png' /></a> </div> </div> </div> <div class="wrap1"> <div class="wrap2"> <div class="wrap3"> <a href='video/rmerl_rocket_ship.flv' rel='shadowbox'><img class='thumb' src='thumbs/thumb_rocket.png' /></a> </div> </div> </div> <div class="wrap1"> <div class="wrap2"> <div class="wrap3"> <a href='video/rmerl_solar_system.flv' rel='shadowbox'><img class='thumb' src='thumbs/thumb_solar_system.png' /></a> </div> </div> </div> </div> <br /> <div style='text-align:center;width:480px;'> <div class="wrap1"> <div class="wrap2"> <div class="wrap3"> <a href='video/rmerl_space_ship.flv' rel='shadowbox'><img class='thumb' src='thumbs/thumb_space_ship.png' /></a> </div> </div> </div> <div class="wrap1"> <div class="wrap2"> <div class="wrap3"> <a href='video/rmerl_still_life.flv' rel='shadowbox'><img class='thumb' src='thumbs/thumb_still_life.png' /></a> </div> </div> </div> <div class="wrap1"> <div class="wrap2"> <div class="wrap3"> <a href='video/rmerl_walkthrough.flv' rel='shadowbox'><img class='thumb' src='thumbs/thumb_walkthrough.png' /></a> </div> </div> </div> </div> </div></center> </body> </html> ```

We are using a UITextView with a dark background. As such we have made the text white color in order to be easier to read. The problem is the magnify window that pops up when you hold down your finger to move the insertion point uses white for the text color as well. This makes it impossible to see exactly where the insertion point is. Is it possible to independently control the text color used in the magnify window? Here is a screen shot illustrating the problem. 

How can I control the color of the text used in a magnify window?

I'm trying to create an activity that presents some data to the user. The data is such that it can be divided into 'words', each being a widget, and sequence of 'words' would form the data ('sentence'?), the ViewGroup widget containing the words. As space required for all 'words' in a 'sentence' would exceed the available horizontal space on the display, I would like to wrap these 'sentences' as you would a normal piece of text. The following code: ``` public class WrapTest extends Activity { /** Called when the activity is first created. */ @Override public void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); LinearLayout l = new LinearLayout(this); LinearLayout.LayoutParams lp = new LinearLayout.LayoutParams( LinearLayout.LayoutParams.FILL_PARENT, LinearLayout.LayoutParams.WRAP_CONTENT); LinearLayout.LayoutParams mlp = new LinearLayout.LayoutParams( new ViewGroup.MarginLayoutParams( LinearLayout.LayoutParams.WRAP_CONTENT, LinearLayout.LayoutParams.WRAP_CONTENT)); mlp.setMargins(0, 0, 2, 0); for (int i = 0; i < 10; i++) { TextView t = new TextView(this); t.setText("Hello"); t.setBackgroundColor(Color.RED); t.setSingleLine(true); l.addView(t, mlp); } setContentView(l, lp); } } ``` yields something like the left picture, but I would want a layout presenting the same widgets like in the right one.   Is there such a layout or combination of layouts and parameters, or do I have to implement my own ViewGroup for this?

I've been looking through the iPhone's UI catalog and cant seem to find what I'm looking for. Essentially I want a customizable version of the 'in call' menu as found on the iPhone so I can use my own icons and call my own functions. Example of 'in call' menu:  UIAlertView is the nearest thing I have found to it but it is still a way off from what I want. A friend said that someone had coded an open source version but he couldn't recall where it was. I've looked but can't find it. Any ideas?

I'm trying to think an interface for a time-keeping system that will let users see "at a glance" how much time still needs to be completed. This is complicated by the fact that there are no fixed hours - employees must work at least 6 hours on any given week day, and at the end of each month should have worked 7.5 hours for each week day that month. 7.5 hours either way can be carried over to next month. Employees can also take up to 1 morning and 1 afternoon per month 'flex' time. Time needs should be recorded by 10.15 the following day, but this rule is bent during busy times, and end of week and particularly end of month boundaries become more important. So what's the most readable format to display the currently entered time and highlight approaching deadlines for uncompleted entries, while still giving a feeling for how far ahead/behind track the employee is (i.e. if you have a week to go that month and you're 8 hours ahead you could schedule a little extra duvet time). My first take was a bar chart for each day with a red line at 6. But this doesn't give you any idea of how far ahead or behind you are for each day or month or whether you are close to missing a deadline... (Please excuse the horrible mockup) Maybe I'm trying to convey too much info in one place? -- Here's a mockup of time recorded v.s. time required as suggested by Dickon Reed  -- EDIT: this side works great for stuff like this. i'm going to kick some of these ideas around in the morning and hopefully get something posted back here.

I'm stuck right now with defining the dimension of each line. The list I want to scrape has various colors in it, and what disturbs me the most a selection:  As you can see the picture I try to analyze got a white background with green text. The selection background is grey with black text. And every second line has a slightly greyer background, but I managed to manipulate the contrast with a ColorMatrix. Just for reference, I do have some other ColorMatrizes like Greyscale, Negative, SetContrast, SetBrightness and so on. My method, which is searching the lines does work good with the most part of the picture, but the selection brakes it. So now I'm stuck and don't know what to do. I googled for an hour, but didn't find a solution. --- I thought, that maybe I can transform the background grey from the selection to white without affecting the text and greyscale the rest of the picture. But I can't find a ColorMatrix which does the job. Do you know one or got a better solution?

I have a UIViewController that allows me to view and edit information of a class. It is only allocated once but it's number of rows,sections and data is passed to it depending on the value the user selected. For example. Here it is editing a name & type property (Header view of table is too big.. I did this so you will see the weirdness underneath)  So I enter a name and it all displays fine. Then I click on the address property and the detail view now looks like this:  Everything Ok so far. If i click cancel and go back to edit the name property it displays fine. The problem is this. I scroll down the address table like so:  And then click save/cancel. Now when I go back to edit the name property, the tableview looks like this!  It's as though the previous table is still visible through the header view of the table..? My viewWillAppear: method for this uiviewcontroller looks like this: ``` - (void)viewWillAppear:(BOOL)animated { NSLog(@"Retain count of poolcopy is %d\n\n", [self.thePoolFacilityCopy retainCount] ); //This will be a reference to find our which pool Instance field we are editing. self.sectionFromParentTable = self.cellPath.section; //This will only be used by the arrays self.rowFromPreviousTable = self.cellPath.row; NSString *sectionName; switch (self.sectionFromParentTable) { case KNameIndex: sectionName = @"name"; break; case KAddressIndex: sectionName = @"address"; break; case KPhoneNumberIndex: sectionName = @"phone"; break; case KWebAddressIndex: sectionName = @"url"; break; case KPricesIndex: sectionName = @"prices"; break; case KPoolIndex: sectionName = @"pools"; default: break; } self.title = [NSString stringWithFormat:@"Editing %@", sectionName]; // use an empty view to position the cells in the vertical center of the portion of the view not covered by // the keyboard if (self.sectionFromParentTable == KPhoneNumberIndex || self.sectionFromParentTable == KWebAddressIndex) { UIView *singleSectionHeaderView = [[UIView alloc] initWithFrame:CGRectMake(0, 0, 5, 60)]; self.theTableView.tableHeaderView = singleSectionHeaderView; [singleSectionHeaderView release]; self.theTableView.tableFooterView = [[[UIView alloc] initWithFrame:CGRectMake(0, 0, 5, 10)]autorelease]; } else if (self.sectionFromParentTable == KAddressIndex) { UIView *addressHeaderView = [[UIView alloc] initWithFrame:CGRectMake(0, 0, 5, 0)]; self.theTableView.tableHeaderView = addressHeaderView; [addressHeaderView release]; self.theTableView.tableFooterView = [[[UIView alloc] initWithFrame:CGRectMake(0, 0, 5, 250)]autorelease]; } else if (self.sectionFromParentTable == KPoolIndex) { UIView *poolHeaderView = [[UIView alloc] initWithFrame:CGRectMake(0, 0, 5, 2)]; self.theTableView.tableHeaderView = poolHeaderView; [poolHeaderView release]; self.theTableView.tableFooterView = [[[UIView alloc] initWithFrame:CGRectMake(0, 0, 5, 10)]autorelease]; } else { UIView *doubleSectionHeaderView = [[UIView alloc] initWithFrame:CGRectMake(0, 0, 5, 30)]; self.theTableView.tableHeaderView = doubleSectionHeaderView; [doubleSectionHeaderView release]; self.theTableView.tableFooterView = [[[UIView alloc] initWithFrame:CGRectMake(0, 0, 5, 10)]autorelease]; } [self.theTableView reloadData]; ``` } In the picture where the table looks messed up the cellForRowAtIndexPath method is only being called twice, even though there are 3 cells visible (2 normal cells and one weird cell). The weird cell moves with the scroll and is still clickable. I can fix this problem by commenting out the following lines in this method. However I don't want to have to allocate a new controller everytime someone wants to edit a detail: ``` - (PoolFacilityDetailEditController *)childController { // Instantiate the editing view controller if necessary. // if (childController == nil) { PoolFacilityDetailEditController *controller = [[PoolFacilityDetailEditController alloc] initWithNibName:@"PoolFacilityDetailEditController" bundle:nil]; self.childController = controller; [controller release]; // } return childController; } ```

Here is my setup: one navigation controller, two views The first view, the rootview, displays the statusbar and navigation bar (portrait view). When the rootviewController senses rotation, it hides the nav bar and status bar and then it pushes view 2 onto the navigation controller (in landscape now). This part works as expected. When View2 viewcontroller senses rotation (back to portrait), it pops itself of the navigation controller, revealing view 1. View 1 then unhides the status bar and nav bar. From here, it gets weird. Depending on when I unhide the navigation bar, I get strange results. As you can see below (The beaker photo should be just below the navbar at the top of the screen). I have tried unhiding the navigation bar in: - - - Nothing works. Any Idea what is going on? This should be simple, but maybe I am doing things in the wrong places.

# The Scenario I am building a custom CMS for a communications application. The users can upload images to the server and then later reference them in posts they write using markdown. Images are stored in a database and referenced with a url of the form `images/{id}`. A custom image handler retrieves these and sets a far future expires header so they aren't fetched over and over again. Storing the images in the file system is not an option per the customer. Posts are stored in the database as markdown and as html for performance. ### Markdown ``` ###Header Lorem Ipsum dolor sit amet.  ``` ### HTML ``` <h3>Header</h3> <p> Lorem Ipsum dolor sit amet. <img alt="funny cat" src="images/25" /> </p> ``` # The Problem These images are also editable. From a caching perspective this presents a problem. When an image is edited I need to ensure that the browser gets the latest version. I have come up with the following solutions, all of which I have found to be lacking. # Possible Solutions ### Version Field Store a version field with the image. Increment it when the image is edited producing urls of the form `images/{id}/version/{version}`. This is nice if image urls are always generated from the database. However, I am storing urls in posts as text and would have to preprocess possibly large swaths of text for these requests. Also, linking an image would be troublesome since a url becomes stale after an image is edited. This is probably not a good idea. ### New Url When an image is edited, store it as a new entry in the database. This means no version upkeep, but old links and old posts suffer from the same issues. They're never updated. The performance would be good, but the problem remains. ### 304 - Not Modified Store a last edited field for each image. When a conditional request comes in return http status 304 - Not Modified, reducing bandwidth usage. This seems like the best solution I've got so far. The image is cached unless edited, but I've never used this approach before. If there are 50 images on the page there are still 50 requests to the server. Bandwidth will be reduced, but the latency remains. Is this approach worth that cost? # The Question I have very little experience in this area and I'm hoping all of you have more. Are any of the above solutions viable? If so what is your experience with them? If not what is a better approach?

I really enjoyed using the [Developer Toolbar](http://www.microsoft.com/en-us/download/details.aspx?id=18359) with IE7, and recently upgraded to IE8 to take advantage of (what appeared to be) more full-featured [developer tools](http://blogs.msdn.com/ie/archive/2008/03/07/improved-productivity-through-internet-explorer-8-developer-tools.aspx). The IE8 tool is really excellent (finally rivals FireBug), but I can't seem to inspect inside an iframe, which I could with the IE7 toolbar. I'd prefer not to downgrade to IE7 because I like some of the other features of the IE8 tools, but the ability to inspect inside an iframe is a deal breaker. Also, firebug is of limited utility to me because our site is an internally-deployed intranet app, which means "browser compatibility" is a very low priority, major functionality is often broken in FireFox. Here's what the IE8 tools look like around the iframe  In firebug, I can see an `<html>` element under the iframe, which I can expand just like the rest of the page The `<iframe>` in question has its `src` attribute set server-side (in the ASP.NET code-behind) UPDATE: I get the same result on this [Iframe example page](http://www.htmlcodetutorial.com/frames/_IFRAME.html). If anyone can use the IE8 developer tools to inspect inside that `iframe` then I'd like to hear about it.

How to create trapezoid tabs in WPF tab control? I'd like to create non rectangular tabs that look like tabs in Google Chrome or like tabs in code editor of VS 2008. Can it be done with WPF styles or it must be drawn in code? Is there any example of code available on internet? There is lots of examples that show how to round corners or change colors of tabs, but I could not find any that changes geometry of tab like this two examples:   Tabs in this two examples are not rectangles, but trapezes.

Ok I understand that this error mostly comes from sending a method call or trying to access a variable that has already been deallocated. Here is the problem: ``` .h @interface TimeEntry : NSObject <NSCopying, NSCoding> { NSDate *from; NSDate *to; NSString *information; } @property (nonatomic, retain) NSDate *from; @property (nonatomic, retain) NSDate *to; @property (nonatomic, copy) NSString *information; @end ``` And my classes' dealloc. ``` -(void)dealloc{ [super dealloc]; [to release]; [from release]; [information release]; } ``` This is the traceback thing when I get the EXC_BAD_ACCESS error  So I'm sending a message to an object that has been deallocated right? So I turned on NSZombie and this STOPPED my crashes. It didn't give me some lovely crash report like I'd hoped. Instead it just kept the program from crashing. In the dealloc method above if I comment out [to release] and [from release] the app doesnt crash. If I comment out just one of them.. it doesn't crash. In the debug window to and from have different memory addresses. How can memory management be so hard!!!! Any clues anyone? Thanks, Dan

This question applies to Windows Vista! I have an application which normally works without administrative privileges. There is one activity which does need administrative privilege but I don't want to start the application itself with higher privileges when I know most of time user wont even be using that feature. I am thinking about certain method by which I can elevate the privileges of application on some event (such as press of a button). Example:  If user clicks this button then he is prompted with UAC dialog or consent. How can I do this?

I use this code to copy and instance of my class ``` //Create the copy and pass it onto edit controller PoolFacility *poolCopy = [self.thePoolFacility copy]; self.childController.thePoolFacilityCopy = poolCopy; [poolCopy release]; ``` Now when I view the variables in the debugger, how come some of the class' fields have the same memory address? Shouldn't they be independent? According to Apple > The NSCopying protocol declares a method for providing functional copies of an object. The exact meaning of “copy” can vary from class to class, but a copy must be a functionally independent object with values identical to the original at the time the copy was made. The two instances are poolCopy & the original thePoolFacility  My class copy method looks like this: ``` - (id)copyWithZone:(NSZone *)zone { PoolFacility *copy = [[[self class] allocWithZone:zone]init]; copy.name = [self.name copy]; copy.type = [self.type copy]; copy.phoneNumber = [self.phoneNumber copy]; //make sure I get proper copies of my dictionaries copy.address = [self.address mutableCopy]; copy.webAddress = [self.webAddress copy]; copy.prices = [self.prices mutableCopy]; copy.pools = [self.pools mutableCopy]; return copy; } ```

Ok so I've got a really annoying bug in my app. It's driving me crazy and I'm sure it's beyond my skill level as I am learning as I go. Here is the initial rundown of the bug: [A shot in the dark - Application bug](https://stackoverflow.com/questions/573837/a-shot-in-the-dark-application-bug) However I have found a way to consistently reproduce the bug (only on the device not in the simulator) First you create a new Pool and save it. Then add 20 blank time entires into one day. Save it and this is where the problems begin. (when you go back to the main detail view the tableview has put itself out of editing mode with being told to do so). Now if you go back to the day to see the time entries you just added they are still there. If you go back to the main overall tableview listing all pools and now go back to the day you added the times they have dissapeared. Add one time and it all saves fine. Add twenty and it doesn't save. WTF!! Main Menu listing Pools:  Detail view:  Edit View:  Time Edit View:  Add a time:  I'd appreciate any more guesses. But as well as this question I'm offering a bounty of £25 (Sorry I'm a poor student) to whoever is good enough to fix this bug first! if your interested my email is danmorgz[at]gmail.com Thanks, Dan

I have a tabbed application with each tab having a navigation controller. I use helper code to push a view/controller pair onto the navigation stack yet when I call this same code from two different places I get (suprizingly) different results. In one case the view renders lower than in the other case, seemingly lower by a navigation bar height. Pushed from one tab (in good position) :  Pushed from another tab (too low):  The XIB:  Here is the push code: ``` + (void)navigateToLocation:(Location*)location controller:(UIViewController*)vc withDelegate:(NSObject <LocationEditDelegate> *)delegate { LocationDetailsViewController *detailsController = [[LocationDetailsViewController alloc] initWithNibName:@"LocationDetailsViewController" bundle:nil]; detailsController.title = [location display]; detailsController.location = location; detailsController.delegate = delegate; // Push the detail view controller [[vc navigationController] pushViewController:detailsController animated:YES]; [detailsController release]; } ``` Can anybody help me understand what might be going on, and how I get inside this? I have 2.2.1 installed and build/deploy using 2.2. Since comments do not appear to show, I am annotating at the bottom. Edit this if I am doing things incorrectly: -

I'm writing some software that automatically connects a Bluetooth device using the Windows [Bluetooth API](http://msdn.microsoft.com/en-us/library/aa362932(VS.85).aspx). When it connects, Windows automatically starts installing the Bluetooth HID device driver, as expected:  This takes about 10-15 seconds, after which Windows displays the familar "ready for use" message:  The problem is that `BluetoothSetServiceState()` returns as soon as the driver install , not when the device is actually ready for use. This causes some problems for my code, because it invokes a separate library for device communication as soon as it's "connected". The first few calls fail because the drivers haven't finished installing, and making those connection attempts appears to interfere with the driver installation, because if I try to use the communication library before the driver installation has finished Windows wants to restart before the device can be used. What I'm looking for is a way to hook that "ready to use" event, when driver installation has actually finished, so I don't make my communication library calls prematurely. Is there some Windows API call I can use to either register a function callback or directly polling the state of driver installation? I'm writing this in vanilla C/C++, no .NET. Thanks for your help!

I'm working on an iPhone game, and trying to use a UIScrollView to display some icons, which I then want to enable the user to drag off the bar being scrolled, onto another view (basically, dragging them from their hand into play on the game board). The problem is that the UIScrollView clips everything outside it's own bounds. Here is a picture of what I'm trying to do:  Functionally, it actually works, in that you can drag the icons up to the white board fine...but you can't see them as you are dragging...which is not acceptable. Does anyone know if you can temporarily disable the clipping that a scroll view does, or is there some way to get around it? Hacky or not, I would really like to make it happen. Does anyone have any other possible solutions for this? Or maybe any alternate approaches? I've considered if maybe a page view might work, but haven't tried it yet...and it's not at all as good of a solution as the scroll view. Worst case I can just go back to not having the bar scrollable, but that really puts a damper on some of my game mechanics, and I'm really not too excited about that.

Looking for online resources to implement a virtual drive functionality similar to ones implemented in products listed  The solution should be cross OS (win, pc, linux) preferably using a well behaving framework. Currently the answer to this question is widely dispersed with no clear option on what to use: Current suggestions I've found: 1. Fuse (not really sure on the status of various windows ports) 2. Dokan library 3. Custom namespace extensions (windows only, sources in various CodeProject articles) 4. Commercial frameworks (windows) - LogicNP, Eldos 5. WebDav Please list one suggestion per answer and I'll update the question accordingly. The purpose of the question is to create the best reference point for such questions... It seems WebDav would be easiest to implement cross OS so further information on this would be appreciated.

Given the following HTML page a horizontal line appears at the top of the table where the 1st row would have a 2nd and 3rd cell (if they were defined). ``` <html> <head> <Title>Test Page</Title> <style type="text/css"> table { margin:10px 0 10px 0; padding:0; margin: 0 0 0 0; border-collapse: collapse; border: 0; } td { border:1px solid #CCCCCC; padding:5px; } </style> </head> <body> <table> <tr> <td>Test Title</td> </tr> <tr> <td>Sub Title</td> <td>Sub Title</td> <td>Sub Title</td> </tr> <table> </body> </html> ``` I would like the line (highlighted below) removed by modifying CSS only. This line appears in Firefox but not IE6.  Note that I cannot modify the HTML in any way as this is generated by a third party system (the example above is simply to highlight the issue). This third-party system only allows me to modify the CSS.

I have a DIV container of 100% width holding x divs. The last child DIV floats right, the rest float left. All child DIV's remain in a line so long as they fit in the bar (all oriented left, except for the last div which sits by itself on the right). If the window is resized smaller and the children don't have enough room, they collapse from their horizontal orientation (which I don't want). To fix this, I know I can set a min-width of the DIV container, the issue is that there is a variable amount of DIVs in the container, of variable width. I'd like to simulate being able to set a min-width where of the container where min-width = width of all children, but I cannot compute these because they are variable (which would simulate flexible space between the right div and the rest, but not let them get closer than they should be allowed (hence collapsing the divs)). I know this is a little unclear so here's a picture:  Thanks!

As I see it, there are two ways to handle mouse events to draw a picture. The first is to detect when the mouse moves and draw a line to where the mouse is, shown [here](http://www.cs.iupui.edu/~aharris/pygame/ch05/paint.py). However, the problem with this is that with a large brush size, many gaps appear between each "line" that is not straight since it is using the line's stroke size to create thick lines. The other way is to draw circles when the mouse moves as is shown [here](http://www.ida.liu.se/~ETE257/timetable/LecturePythonPygame2.html). The problem with this is that gaps appear between each circle if the mouse moves faster than the computer detects mouse input. Here's a screenshot with my issues with both:  What is the best way to implement a brush like MS Paint's, with a decently-big brush size with no gaps in the stroke of the line or no gaps between each circle?

Never asked a question here before, I'll try to lay this out as succinctly as possible. I've got a Recipe class, that contains lists of three different types of Ingredient Uses. These classes all inherit from the base, IngredientUse. So the mapping looks like this: ``` <class name="IngredientUse" table="IngredientUses"> <id name="Id" type="Int64" column="Id"> <generator class="native"/> </id> <!--some other properties--> <property name="RecipeId" column="RecipeId"/> <joined-subclass name="AdditionUse" table="AdditionUses"> <key column="Id" foreign-key="FK_AdditionUses_IngredientUses"/> <many-to-one name="AdditionUsed" column="AdditionUsed" class="Addition" foreign-key="FK_AdditionUses_Additions"/> </joined-subclass> </class> ``` The one causing problems here is the RecipeId. From the recipe, I have three separate lists of uses for different ingredient types, defined like so: ``` <bag name="AdditionsUsed" cascade="all" lazy="false"> <key column="RecipeId"/> <one-to-many class="AdditionUse"/> </bag> ``` Now, I'm running into problems trying to load these lists. It has something to do with the inheritance. When I look at the SQL Generated, I see this: ``` SELECT additionsused0_.RecipeId as RecipeId1_ --other columns not really important FROM AdditionUses additionsused0_ inner join IngredientUses additionsused0_1_ on additionsused0_.Id=additionsused0_1_.Id WHERE additionsused0_.RecipeId=@p0; @p0 = '11' ``` Notice that its' looking for the RecipeId in the subclass' table, and not the base table where the column is actually contained. I know I could just define a separate table for each ingredient type, but that will cause me problems because there are some situations (ie pricing) where I don't need the additional columns in the subclass table, and would like to be able to load all the ingredients into the same list at once. I'm certain I must be missing something here, figured someone more familiar with NHibernate on this site might recognize it right off the bat. Thanks in advance. in case I wasn't clear about what I'm trying to do, this diagram might help (excuse my shoddy UML, hope it doesn't muddy the waters). There is also an Ingredient base class, and the same subtypes off of that.

I'm a very frequent user of the GNU [Autotools](http://en.wikipedia.org/wiki/GNU_build_system) (mostly [Autoconf](http://en.wikipedia.org/wiki/Autoconf), occasionally [Libtool](http://en.wikipedia.org/wiki/GNU_Libtool)). I'm working on a project where portability is going to be a sticking point.. Yet, the rest of the team is just not comfortable working with [m4](http://en.wikipedia.org/wiki/M4_%28computer_language%29#Free_software_implementations). I got [this](http://xkcd.com/297/) in my inbox from not one, but four people:  Anyway, perhaps someone could recommend something Python or PHP based? I'm working on the C end of a much larger tree; I can be sure either Python or PHP 5 will be present, as they are prerequisites.

I've got a `QComboBox` with a custom list object.  The custom list object has a custom `mousePressEvent` so that when the user click on one of the circles with a +/- (a twisty), the list is expanded/collapsed. When I use the list with the combo box, when the user clicks on a twisty, the list is expanded/collapsed, but the selection is changed, and the list is hidden. How can I filter this so that when the user click on a twisty, the selection is not changed, and the list not hidden. ## Additional screenshots All of the nodes collapsed:  List hidden:

It works fine in IE/FF but in chrome it seems that it can't find the background image and makes the background nothing.

If you set `ResizeMode="CanResizeWithGrip"` on a WPF `Window` then a resize grip is shown in the lower right corner, as below:  If you set `WindowStyle="None"` as well the title bar disappears but the grey bevelled edge remains until you set `ResizeMode="NoResize"`. Unfortunately, with this combination of properties set, the resize grip also disappears. I have overridden the `Window`'s `ControlTemplate` via a custom `Style`. I want to specify the border of the window myself, and I don't need users to be able to resize the window from all four sides, but I do need a resize grip. Can someone detail a simple way to meet all of these criteria? 1. Do not have a border on the Window apart from the one I specify myself in a ControlTemplate. 2. Do have a working resize grip in the lower right corner. 3. Do not have a title bar.

How to create a WPF Window without a border that can be resized via a grip only?

: It is not possible to use other trusted certificate authorities now. Question and answer is not obsolete: WinQual still rejects the signature:  when we've already established that it is a valid digital signature:  For completeness, i will leave the edit below that did; just to point out how wrong he was. And he can live with that shame: --- --- In 2005 i tried to establish a WinQual account with Microsoft, so i could pick up our (if any) crash dump files submitted automatically through Windows Error Reporting (WER). i was not allowed to have my crash dumps, because i don't have a Verisign certificate. Instead i have a cheaper one, generated by a Verisign subsidiary: Thawte. --- The method in which you join is: you digitally sign a sample exe they provide. This proves that you are the same signer that signed apps that they got crash dumps from in the wild. Cryptographically, the private key is needed to generate a digital signature on an executable. Only the holder of that private key can create a signature with for the matching public key. It doesn't matter who generated that private key. That includes certificates that are generated from: - - [Wells Fargo](http://en.wikipedia.org/wiki/Wells_Fargo)- - - - [QuoVadis](http://en.wikipedia.org/wiki/QuoVadis)- [GoDaddy](http://en.wikipedia.org/wiki/GoDaddy)- [Entrust](http://en.wikipedia.org/wiki/Entrust)- [Cybertrust](http://en.wikipedia.org/wiki/Cybertrust)- [GeoTrust](http://en.wikipedia.org/wiki/GeoTrust)- [GlobalSign](http://en.wikipedia.org/wiki/GlobalSign)- [Comodo](http://en.wikipedia.org/wiki/Comodo)- [Thawte](http://en.wikipedia.org/wiki/Thawte)- Yet Microsof's WinQual only accepts digital certificates generated by Verisign. Not even Verisign's subsidiaries are good enough (Thawte). Can anyone think of any technical, legal or ethical reason why Microsoft doesn't want to accept code-signing certificates? The WinQual site says: > A digital certificate helps protect your company from individuals who seek to impersonate members of your staff or who would otherwise commit acts of fraud against your company. Using a digital certificate enables proof of an identity for a user or an organization. Is somehow a Thawte digital certificate not secure? --- Two years later, i sent a reminder notice to WinQual that i've been waiting to be able to get at my crash dumps. The response from WinQual team was: > Hello,Thanks for the reminder. We have notified the appropriate people that this is still a request. --- In 2008 i [asked this question](http://social.msdn.microsoft.com/Forums/en-US/isvwindowserrors/thread/92419a64-af22-4527-bcf4-eeeb0d2423cd/) in a Microsoft support forum, and the response was: > We are only setup to accept VeriSign Certificates at this point. We have not had an overwhelming demand to support other types of certificates. What can it possibly mean to not be "setup" to accept other kinds of certificates? If the thumbprint of the key that signed the WinQual.exe test app is the same as the thumbprint that signed the executable who's crash dump you got in the wild: it is proven - And it's not like there's a special API to check if a Verisign digital signature is valid, as opposed to all other digital signatures. A valid signature is valid no matter who generated the key. Microsoft free to not the signer, but that's not the same as identity. --- So that is my question, can anyone think of any practical reason why WinQual isn't setup to support digital signatures? One person theorized that the answer is that they're just lazy: > Not that I know but I would assume that the team running the winQual system is a live team and not a dev team - as in, personality and skillset geared towards maintenance of existing systems. I could be wrong though. They don't want to do work to change it. But can anyone think of anything that would need to be changed? It's the same logic no matter what generated the key: "does the thumbprint match". What am i missing? --- ## Update It is nice to hear the stories of other developers. This way i know that i'm not alone, and the question can serve as a vehicle for change on Microsoft's part. And even if my original intent was a complaining rant, in order to keep this a valid StackOverflow question i'm looking for a technical reason Microsoft could only accept Verisign certificates. The crypto API doesn't care what the name of the company that issued a certificate is: it only cares that the chain of signers leads back to a trusted root. What could possibly be going on that Microsoft specifically isn't using the established crypto infrastructure, but instead is limited itself to Verisign? If anyone could point to any blog entry, where a program manager or developer explains , i would, perhaps, be satisfied. --- ## Update Two People seem to be missing the point of my question. Windows already has the code infrastructure to ensure that a digital signing certificate is trusted by a root authority. Here's a screenshot of a digital signature on one of our signed executables. You can see our certificate was signed by Thawte's Code-Signing authority certificate, which in turn is signed by Thawte: [](https://i.stack.imgur.com/79a2A.png) And the "thawte" certificate ships by default with Windows: [](https://i.stack.imgur.com/rAIpA.png) The is good enough that every copy of Windows and Internet Explorer already trust it. And there already is an established API to check if a certificate is valid (i.e. trusted). When WinQual guys came along, they would have had to have to avoid checking the correct way, and instead rolled their own solution, hard-coding only Verisign as a trusted root. would they go to ignore the other trusted root authorities, authorities that ship that their code is running on, and instead hard-code Verisign? Rather than do it the way everyone else does (Windows Explorer, Firefox, Chrome, Internet Explorer, Opera, CertMgr, etc), they only allow Verisign. And my question is why. `Why would WER not accept code-signing certificates?` If it was simply: - - - - - - - - - - - - ...that would be fine. Except i don't believe it. i don't believe that it was test code that made into production. i get the sense that it is a conscious, specific, decision that made them ignore other signers. And that they do, and will continue to, only honor Verisign. But for the life of me i can't think of the reason.

I need to make a chart with an optimized axis maximum value. The current method I have of making charts simply uses the maximum value of all the graphs, then divides it by ten, and uses that as grid lines. I didn't write it. These graphs have been changed. As soon as I fixed the code, my dynamic graphs started working, making this question nonsensical (because the examples no longer had any errors in them). I've updated these with static images, but some of the answers refrence different values. Keep that in mind. [](https://i.stack.imgur.com/W5fPK.png) There were between 12003 and 14003 inbound calls so far in February. Informative, but ugly. I'd like to avoid charts that look like a monkey came up with the -axis numbers. Using the Google charts API helps a little bit, but it's still not quite what I want.  The numbers are clean, but the top of the y value is always the same as the maximum value on the chart. This chart scales from 0 to 1357. I need to have calculated the proper value of 1400, . --- I'm throwing in [rbobby](https://stackoverflow.com/questions/611878/reasonable-optimized-chart-scaling/611979#611979)'s defanition of a 'nice' number here because it explains it so well. - - - - ## Solution [](https://i.stack.imgur.com/ubIkH.png) I found the way to get the results that I want using a modified version of Mark Ransom's idea. Fist, Mark Ransom's code determines the optimum spacing between ticks, when given the number of ticks. Sometimes this number ends up being more than twice what the highest value on the chart is, depending on how many grid lines you want. What I'm doing is I'm running Mark's code with 5, 6, 7, 8, 9, and 10 grid lines (ticks) to find which of those is the lowest. With a value of 23, the height of the chart goes to 25, with a grid line at 5, 10, 15, 20, and 25. With a value of 26, the chart's height is 30, with grid lines at 5, 10, 15, 20, 25, and 30. It has the same spacing between grid lines, but there are more of them. So here's the steps to just-about copy what Excel does to make charts all fancy. 1. Temporarily bump up the chart's highest value by about 5% (so that there is always some space between the chart's highest point and the top of the chart area. We want 99.9 to round up to 120) 2. Find the optimum grid line placement for 5, 6, 7, 8, 9, and 10 grid lines. 3. Pick out the lowest of those numbers. Remember the number of grid lines it took to get that value. 4. Now you have the optimum chart height. The lines/bar will never butt up against the top of the chart and you have the optimum number of ticks. PHP: ``` function roundUp($maxValue){ $optiMax = $maxValue * 2; for ($i = 5; $i <= 10; $i++){ $tmpMaxValue = bestTick($maxValue,$i); if (($optiMax > $tmpMaxValue) and ($tmpMaxValue > ($maxValue + $maxValue * 0.05))){ $optiMax = $tmpMaxValue; $optiTicks = $i; } } return $optiMax; } function bestTick($maxValue, $mostTicks){ $minimum = $maxValue / $mostTicks; $magnitude = pow(10,floor(log($minimum) / log(10))); $residual = $minimum / $magnitude; if ($residual > 5){ $tick = 10 * $magnitude; } elseif ($residual > 2) { $tick = 5 * $magnitude; } elseif ($residual > 1){ $tick = 2 * $magnitude; } else { $tick = $magnitude; } return ($tick * $mostTicks); } ``` Python: ``` import math def BestTick(largest, mostticks): minimum = largest / mostticks magnitude = 10 ** math.floor(math.log(minimum) / math.log(10)) residual = minimum / magnitude if residual > 5: tick = 10 * magnitude elif residual > 2: tick = 5 * magnitude elif residual > 1: tick = 2 * magnitude else: tick = magnitude return tick value = int(input("")) optMax = value * 2 for i in range(5,11): maxValue = BestTick(value,i) * i print maxValue if (optMax > maxValue) and (maxValue > value + (value*.05)): optMax = maxValue optTicks = i print "\nTest Value: " + str(value + (value * .05)) + "\n\nChart Height: " + str(optMax) + " Ticks: " + str(optTicks) ```

Now I drag a file to the app icon in the dock, this app is based on document . I found that no little image on the left of window title after the app is run and the mainwindow is open . but when I drag a file to the dock icon before the app run and use this method to run the app , a little image on the left of window title to show the file ,just like the xcode etc. Now I want to show the little image both way or not to show the little image both way , How to do ? I think that it maybe the window property based on document , but I don't know how to fix it ? Thanks --- I used the `[mainWindow setTitle:tmp];`, but icon still appear. when I used `setTitleWithRepresentedFilename:` I found that both icon and window title name both are modify, in the document class I overload the `-(void)displayName;` so I want to the window title is fixed anytime.
