618,894 | 1 | null | null | 4 | 1,203 | We are facing a weird problem in IE6. The page works fine in Firefox and IE7.
We have a page which has a div and a iframe within that div
Example:
```
<html>
<body>
...
<div>
<iframe src="page.aspx" />
</div>
</body>
</html>
```
Now assume page.aspx has this code:
```
<html>
<body>
..
<a href="#" onclick="alert('just an alert');">click me</a>
</body>
</html>
```
Now if user clicks on the link 'click me' then the iframe moves!
Here is a depiction of the behavior:
It seems like none of the code written by us is causing an issue, as the only thing that happens when the user clicks on the link 'click me' is to just show an alert box.
has anybody faced a similar issue? Any pointers about how to resolve this problem?
PS: It is difficult for me to reproduce the problem with a simple example.

619,618 | 1 | 619,919 | null | 7 | 4,325 | I am creating images using PIL that contain numerous exactly placed text strings. My first attempt was to convert pixel fonts into the pil-compatible format as described [here](http://llbb.wordpress.com/2006/11/24/making-pil-font-for-python-image-library/). For example, I download the Silkscreen font and convert it:
```
otf2bdf -p 8pt -o fonts/slkscr.bdf fonts/slkscr.ttf
pilfont.py fonts/slkscr.bdf
```
I can then use the font in PIL like so:
```
import Image, ImageDraw, os, sys, ImageFont
im = Image.new("RGB", (40,10))
draw = ImageDraw.Draw(im)
fn = ImageFont.load('fonts/slkscr.pil')
draw.text((0,0), "Hello", font=fn)
del draw
# write to stdout
im.save(sys.stdout, "PNG")
```
However, the resulting image () does not reflect what the font [should look like](http://kottke.org/plus/type/silkscreen/).
What procedure should I be using to convert and use pixel fonts so that they render as intended?
Thanks in advance.

622,471 | 1 | 622,500 | null | 8 | 14,771 | So I'm building the pacman game in Java to teach myself game programming.
I have the basic game window with the pacman sprite and the ghost sprites drawn, the pacman moves with the arrow keys, doesn't move beyond the walls of the window, etc. Now I'm trying to build the maze, as in this picture:
Without giving me the direct/complete solution to this, can someone guide me as to how this can be built? I'm talking only about the boundaries and the pipes('T' marks) here which you can't go through and you have to go around. Not the dots which the pacman eats yet.
Here are my questions:
1) What's the most efficient algorithm/method for creating this maze? Will it have to be drawn each time the paint() method is called or is there a way to draw it only at the start of the game and never again?
2) How will this actually be drawn to the screen? I assume the `fillRect()` will be used?
3) Any hints on collision detection (so the pacman/ghosts can't go through the walls) would be helpful.
4) Any hints on how the vacant space between the pipes will be calculated so the dots can be filled between them will also be very helpful.
Thanks

In order to test the sheet I need to call some macros, this in turn requires macro security to be set to lowest on the testing servers. (In production macro security will be on). In particular I need to supress this dialog:
One particular PC seems to resist my attempts to configure it, having set macro security to low from Tools->Macro->Secyrity... I exit Excel and return to it, only to find out that macro security has been reverted to "medium"
I'm guessing that I've inherited a PC which has a registry setting that prevents me from downgrading the security, I've searched around and found "[HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Office\11.0\Excel\Security]", however this does not seem to do the trick.
I wonder if there is another way to force macro security to it's lowest setting, either programmatically (via COM) or through a simple registry edit.
UPDATE: I'm on Office 2003. My PCs were pre-owned by other users and may have all kinds of configuration inconsistencies. Of all the PC's under my care this issue only affects one machine. I have full admin rights.

626,541 | 1 | 9,174,392 | null | 8 | 25,822 | I have a SIP application that needs to send UDP packets to set up the SIP calls. SIP has a timeout mechanism to cope with delivery failures. An additional thing I would like to be able to do is detect whether a UDP socket is closed in order having to wait the 32s retransmit interval SIP uses.
The cases I am referring to are when an attempt to send to a UDP socket results in an ICMP Destination Unreachable packet being generated by the remote host. If I attempt to send a UDP packet to a host that's up but that the port is not listening I can see the ICMP message arriving back with a packet tracer but the question is how do I get access to that from my C# code?
I'm playing around with raw sockets but as yet have not been able to get the ICMP packets to be received by my program. The sample below never receives a packet even though ICMP messages are arriving on my PC.
```
Socket icmpListener = new Socket(AddressFamily.InterNetwork, SocketType.Raw, ProtocolType.Icmp);
icmpListener.Bind(new IPEndPoint(IPAddress.Any, 0));
byte[] buffer = new byte[4096];
EndPoint remoteEndPoint = new IPEndPoint(IPAddress.Any, 0);
int bytesRead = icmpListener.ReceiveFrom(buffer, ref remoteEndPoint);
logger.Debug("ICMPListener received " + bytesRead + " from " + remoteEndPoint.ToString());
```
Below is a wireshark trace showing the ICMP responses coming into my PC from an attempt to send a UDP packet from 10.0.0.100 (my PC) to 10.0.0.138 (my router) on a port I know it's not listening on. My problem is how to make use of those ICMP packets to realise the UDP send has failed rather than just waiting for the application to timeout after an arbitrary period?

628,500 | 1 | 631,114 | null | 186 | 114,210 | Lets say I have a text box that I want to fill a whole line. I would give it a style like this:
```
input.wide {display:block; width: 100%}
```
This causes problems because the width is based on the content of the text box. Text boxes have margin, borders, & padding by default, which makes a 100% width text box larger than its container.
For example, here on the right:
Is there any way to make a text box fill the width of its container without expanding beyond it?
Here is some example HTML to show what I mean:
```

```
If this is run, you can see by looking at the "normal" text box that the "wide" text box is sticking out beyond the container. The "normal" text box floats to the actual edge of the container. I'm trying to make the "wide" text box fill its container, without expanding beyond edge like the "normal" text box is.

In the toolbar, I have parent div elements that when clicked, pop up child div elements that need to be positioned directly above the parent element.
For the online status part, I think I'm doing it right since the height of the pop-up for the online status is always the same height.

</div>
</div>

```
Is that the correct way of positioning the pop-up element or should I be doing it differently (i.e., position: relative instead of absolute with some tweaks)?
Here's a screen shot of how it looks:
If that's correct, it brings me to my next problem which is a pop up div element whose size changes based on content returned from an AJAX call. Right now I'm positioning the element based on the number of items returned via JavaScript and JQuery and it's really ugly.
Is there a better way to do it?
First, here's a screen shot of the dynamically filled div element:
CSS:
```
#toolbar #favoritesOnline
{
float:left;
height:21px;
width:180px;
padding-top:4px;
border-right:1px solid #606060;
text-align:center;
}
#toolbar #favoritesOnline .favoritesOnlineIcon
{
padding-right:5px;
}
#toolbar #favoritesOnlinePopUp
{
display:none;
border:1px solid #000000;
width:211px;
background:#2b2b2b;
float:left;
position:absolute;
left:-1px;
}
#toolbar #favoritesOnlineListing
{
overflow:auto;
}
```
HTML (note: it's wrapped in the toolbar div as well):
```
<div id="favoritesOnline" style=" <?php if ($onlinestatus == -1) { echo "display:none;"; } ?> ">
<img class="favoritesOnlineIcon" src="/_assets/img/icons/favorite-small.gif" /><a href="javascript:favoritesOnlineClick();">Favorites Online (<span id="favoritesOnlineCount"><?php echo $favonlinecount; ?></span>)</a>
<div id="favoritesOnlinePopUp">
<div id="popUpTitleBar">
<div id="popUpTitle">Favorites Online</div>
<div id="popUpAction"><a href="javascript:closeFavoritesOnline();">x</a></div>
</div>
<div id="favoritesOnlineListing"></div>
</div>
```
And here's the ugly JavaScript I'm using to position it above the parent element based on the number of items in the list (array[0] is the number of elements).
```
$("#favoritesOnlinePopUp").css('top', ((parseInt(array[0]) * 39) - 5 + 1) * -1);

Lately I've been working with listviews and I've decided to add an for each item indicating whether it's input or output. The icons add fine, but they're not transparent:

hImageList = ImageList_Create(16, 16, ILC_MASK | ILC_COLOR32, 2, 2);
if (hImageList != NULL)
{
iIN = ImageList_AddIcon(hImageList, LoadIcon(hInstance, MAKEINTRESOURCE(101)));
iOUT = ImageList_AddIcon(hImageList, LoadIcon(hInstance, MAKEINTRESOURCE(102)));
}
```
I've tried messing with the flags for `ImageList_Create` & `LoadIcon`/`LoadImage` but have had no luck and to be honest I've run out of ideas.
Any help would be very appreciated.

Provided that the map image starts from the top of the screen (in portrait orientation), the code looks something like:

scrollView.contentSize = mapView.frame.size;
scrollView.maximumZoomScale = MAP_WIDTH / SCREEN_WIDTH;
scrollView.minimumZoomScale = 1;
[scrollView addSubview:mapView];
self.view = scrollView;
}

640,641 | 1 | null | null | 1 | 989 | Our web services are accessed through a router which uses port forwarding to connect to the actual web server. When we are trying to establish a web reference in Visual Studio it seems the .NET framework returns the full URL with a port to Visual Studio for the reference during discovery. Visual Studio then tries to make a connection back to that web service to create a proxy object (or whatever) and is denied because we don't allow access on that non-standard port.
Original web service URL
```
http://webservices.example.com/SomeService.asmx
```
Returned web service URL from router
```

My question is if you know how to make the .NET framework NOT include the port when returning the URL from the discovery call. Here's a diagram depicting this process:

To draw the lines for my rectangles I need to solve for their corners.
I have a rectangle center at (x,y) With a defined Width and Height.
To find the blue points on a non rotated rectangle on top (angle = 0)
It is
`UL = (x-Width/2),(y+height/2)`
`UR = (x+Width/2),(y+height/2)`
`LR = (x+Width/2),(y-height/2)`
`LL = (x-Width/2),(y-height/2)`
How do I find the points if the angle isn't 0?

As a first goal, I would like to have an with only 2 nodes. A "number" which simply outputs a fixed number, and an "Add" node, which takes two inputs and outputs the sum of the two.
As people have answered so-far, I have a rough idea of how to represent the data in code, for example in Python'y looking pseudo-code:
```
class Number:
def __init__(self, value):
self.value = value
def eval(self):
return self.value
class Add:
def __init__(self, input1, input2):
self.input1 = input1
self.input2 = input2
def eval(self):
return self.input1.eval() + self.input2.eval()
a = Number(20)
b = Number(72)
adder = Add(a, b)
print adder.eval()
```
How would I got about wrapping a custom GUI around this? Something like the following, but slightly less hand-drawn!

But I still wonder, how do you go about setting up a real big webproject, which requires dedicated servers.
I've been doing this for 2 years now, I'll probably graduate in another year or 2, but I haven't come about setting up something big and having to spend loads of time to configure it.
I don't even know how to set up a dedicated server. It'll probably live after its namesake: being dedicated to one task. But still, what does that look like? How do I work with it when I have to check things on it? How do I optimize it? How do I set up swift interaction with the other server(s) and how do I keep server load and bandwidth usage down.
These are all questions my school can't answer for me, simply because they have a set of courses to give and can't step outside that. As for me doing it myself, I can't afford stuff like that. And I don't like renting stuff like that either. You give money for some servers that are located several hundred miles away. I don't want that, I want the server within walking distance. I need to be able to walk up to that machine and configure it myself. Yet that's pretty unrealistic, financially speaking.
Also, when I think of servers, I think of this stuff:
Is it cliche to think all good servers look like that?

I am using the selected object in AI file to setup a 9-slice grid (I am not using 9s to scale corners!). I only want that right part to stay static and the rest to scale. Now, also be aware that it must scale, so it must be vector. I cannot tile the part I want to repeat as a rasterized graphic.
So Flex this is easy, WPF not so much. My question to the WPF community is how can you replicate the 9-slice in WPF? I've toyed with exporting these with the AI->XAML Exporter. Embedding the path object into a grid row behaves way too odd and inconsistent.
This is taking an exported path and trying to drop it into a Grid. I should note this Grid is not being used to mimic a 9-slice. I am just using it to layout objects. I simply want the path below to fit into the right-most top corner. It does not even do that....

EDIT2: Here are my results FWIW. Color1 and Color2 are my two colors and the two middle columns are the results of averaging in Lb space and averaging RGB respectively.

I've created some retro-reflective gloves and an IR LED array, coupled with a Wii remote. The Wii remote does internal blob detection and tracks 4 points of IR light and transmits this information to my computer via a bluetooth dongle.
This is based off [Johnny Chung Lee's Wii Research](http://johnnylee.net/projects/wii/). My precise setup is exactly like the graduate students from the Netherlands displayed [here](http://www.cs.rug.nl/~isenberg/VideosAndDemos/Vlaming2008PTI). I can easily track 4 point's positions in 2d space and I've written my basic software to receive and visualize these points.
The Netherlands students have gotten a lot of functionality out of their basic pinch-click recognition. I'd like to take it a step further if I could, and implement some other gestures.
How is gesture recognition usually implemented? Beyond anything trivial, how could I write software to recognize and identify a variety of gestures: various swipes, circular movements, letter tracing, etc.

692,631 | 1 | null | null | 0 | 1,900 | I have two tables, a car table which contains different properties for a car, and a `carmodeldefinition` which is a foreign key to a table with the same name. The `cardefinition` table contains the different cars and models. I have mapped them in the entity framework.
When I try to add a new car within `carmodeldefinition` it simply adds a new `cardefinition` instead of just using the one it finds. The code for it can be found below:
```
DataLayer.Car car = new DataLayer.Car();
car.URL = carBulk.URL;
car.SellerCity = carBulk.SellerCity.ToString();
car.Color = carBulk.Color.ToString();
car.SellerStreet = carBulk.SellerStreet;
car.SellerName = carBulk.SellerName;
car.SellerCountry = carBulk.SellerCountry.ToString();
if (cdDTO != null && cdDTO.CarDefinitionId > 0)
{
car.CarModelDefinition = cdDTO.Transform(cdDTO);
}
mee.AddToCar(car);
mee.SaveChanges();
```
The `cdDTO.Transform(cdDTO)` transforms the `datatransferobject` to an object that can be mapped to the database. The weird thing it that `cdDTO.Transform(cdDTO);` returns the correct object with the correct `cardefintionId`, but when it is inserted, it is just inserted in the bottom with a new `cardefinitionid` (which is the pk).

694,108 | 1 | 723,727 | null | 13 | 9,232 | This question is a little involved. I wrote an algorithm for breaking up a [simple polygon](http://en.wikipedia.org/wiki/Simple_polygon) into convex subpolygons, but now I'm having trouble proving that it's optimal (i.e. minimal number of convex polygons using (added vertices)). My prof is adamant that it can't be done with a greedy algorithm such as this one, but I can't think of a counterexample.
So, if anyone can prove my algorithm is suboptimal (or optimal), I would appreciate it.
The easiest way to explain my algorithm with pictures (these are from an older suboptimal version)
What my algorithm does, is extends the line segments around the point i across until it hits a point on the opposite edge.
If there is no vertex within this range, it creates a new one (the red point) and connects to that:
If there one or more vertices in the range, it connects to the closest one. This produces a decomposition with the fewest number of convex polygons:
However, in some cases it can fail -- in the following figure, if it happens to connect the middle green line first, this will create an extra unneeded polygon. To this I propose double checking all the edges (diagonals) we've added, and check that they are all still necessary. If not, remove it:
In some cases, however, this is not enough. See this figure:
Replacing a-b and c-d with a-c would yield a better solution. In this scenario though, there's no edges to remove so this poses a problem. In this case I suggest an order of preference: when deciding which vertex to connect a reflex vertex to, it should choose the vertex with the highest priority:
lowest) closest vertex
med) closest reflex vertex
highest) closest reflex that is also in range when working backwards (hard to explain) --
In [this figure](http://www.sfu.ca/~mnb2/conv/case4.png), we can see that the reflex vertex 9 chose to connect to 12 (because it was closest), when it would have been better to connect to 5. Both vertices 5 and 12 are in the range as defined by the extended line segments 10-9 and 8-9, but vertex 5 should be given preference because 9 is within the range given by 4-5 and 6-5, but NOT in the range given by 13-12 and 11-12. i.e., the edge 9-12 elimates the reflex vertex at 9, but does NOT eliminate the reflex vertex at 12, but it CAN eliminate the reflex vertex at 5, so 5 should be given preference.
It is possible that the edge 5-12 will still exist with this modified version, but it can be removed during post-processing.
Are there any cases I've missed?
---
Pseudo-code (requested by John Feminella) -- this is missing the bits under Figures 3 and 5
```
assume vertices in `poly` are given in CCW order
let 'good reflex' (better term??) mean that if poly[i] is being compared with poly[j], then poly[i] is in the range given by the rays poly[j-1], poly[j] and poly[j+1], poly[j]
for each vertex poly[i]
if poly[i] is reflex
find the closest point of intersection given by the ray starting at poly[i-1] and extending in the direction of poly[i] (call this lower bound)
repeat for the ray given by poly[i+1], poly[i] (call this upper bound)
if there are no vertices along boundary of the polygon in the range given by the upper and lower bounds
create a new vertex exactly half way between the lower and upper bound points (lower and upper will lie on the same edge)
connect poly[i] to this new point
else
iterate along the vertices in the range given by the lower and upper bounds, for each vertex poly[j]
if poly[j] is a 'good reflex'
if no other good reflexes have been found
save it (overwrite any other vertex found)
else
if it is closer then the other good reflexes vertices, save it
else
if no good reflexes have been found and it is closer than the other vertices found, save it
connect poly[i] to the best candidate
repeat entire algorithm for both halves of the polygon that was just split
// no reflex vertices found, then `poly` is convex
save poly
```
---
Turns out there is one more case I didn't anticipate: [Figure 5]
My algorithm will attempt to connect vertex 1 to 4, unless I add another check to make sure it can. So I propose stuffing everything "in the range" onto a priority queue using the priority scheme I mentioned above, then take the highest priority one, check if it can connect, if not, pop it off and use the next. I this makes my algorithm O(r n log n) if I optimize it right.

I wish to do lazy loading and not use LoadWith<>.
What is the simplest way to explicitly tell Linq to go and lazy fetch a relation just before I need the data itself.
For example: a simple dbml
If I have the following code:
```
TestDbDataContext context = new TestDbDataContext(Settings.Default.TestersConnectionString);
context.ObjectTrackingEnabled = false;
var result = context.Employees.ToList();
foreach (var employee in result)
{
// HERE Should load gift list
foreach (var gift in employee.Gifts)
{
Console.WriteLine(gift.Name);

I know I can write a full query again, but I hope we can find together a better way.

707,657 | 1 | 718,200 | null | 24 | 12,399 | We are trying to come up with a numbering system for the asset system that we are creating, there has been a few heated discussions on this topic in the office so I decided to ask the experts of SO.
Considering the database design below what would be the better option.
Using auto surrogate keys.
```
================= ==================
Road_Number(PK) Segment_Number(PK)
================= ==================
1 1
```
Using program generated PK
```
================= ==================
Road_Number(PK) Segment_Number(PK)
================= ==================
"RD00000001WCK" "00000001.1"
```
(the `00000001.1` means it's the segment of the road. This everytime you add a new segment e.g. `00000001.2`)
Using a bit of both(adding a new column)
```
======================= ==========================
ID(PK) Road_Number(UK) ID(PK) Segment_Number(UK)
======================= ==========================
1 "RD00000001WCK" 1 "00000001.1"
```
Just a bit of background information, we will be using the `Road Number` and `Segment Number` in reports and other documents, so they have to be .
I have always liked keeping things simple so I example 1, but I have been reading that you should not expose your primary keys in reports/documents. So now I'm thinking more along the lines of example 3.
I am also leaning towards example 3 because if we decide to change how our asset numbering is generated it won't have to do cascade updates on a primary key.
What do you think we should do?
Thanks.

When you take a look at Outlook, Calendar Event window, it has "Save Close" button.
So when the functionalities of either or both or changes, that button should change. It obviously violates SRP.
This functionality both saves time and convinient since that is what most of users to do when they save an appoint on a calendar.

At the moment this is a horizontal StackPanel, with the right padding of the checkbox set to 90. This works okay, but if you resize the window it's no good anymore, unless maybe you re-adjust the padding in the window's resize event, but that seems clunky when using a layout manager.
I am coming from a Qt background, and in Qt I would use a "stretch" element between the buttons and the checkbox to push them apart dynamically. Is there a similar concept in WPF? If not, how do I achieve this so that it will support dynamic resizing?

I already browsed the docs but everything I found was [PowerManager](http://developer.android.com/reference/android/os/PowerManager.html) and [KeyguardManager](http://developer.android.com/reference/android/app/KeyguardManager.html). Both seem not to be the solution :-(.
So, does everyone know how to achieve that from a android application? (If special permissions are required, that is no problem but changing the device's settings is not a solution...)
: Or does someone know that this is definitely not possible at all? Btw. craigs solution with sending keys does not work anymore (see comments).

Instead of calling the mouse buttons left, right, and middle, like in any other documentation, they give them colors. It's even suggested to label the mouse to help you learning.
It's 2009 and there are 3 dominant systems left: Windows, MacOS X, Linux
Why do they still stick to this naming scheme? How should I be able to sell this to co-workers, or even customers?
From Squeak by Example:
> [Squeak](http://www.squeak.org/) avoids terms like “left mouse
click” because different computers,
mice, keyboards and personal
configurations mean that different
users will need to press different
physical buttons to achieve the same
effect. Instead, the mouse buttons are
labeled with colors. The mouse button
that you pressed to get the “World”
menu is called the red button; it is
most often used for selecting items in
lists, selecting text, and selecting
menu items. When you start using
Squeak, it can be surprisingly helpful
to actually label your mouse, as shown
in Figure 1.4.

Also, I know that it is an iFrame, but how do they position it so regardless of scrolling it stays positioned at the top? Is it CSS magic?

739,867 | 1 | 764,688 | null | 1 | 353 | I’m on the learning curve up the Silverlight trail. I’m a data-centric developer so I naturally picked up the ADO.NET Data Services client along the way. I’m scratching my head over a real-world scenario and can’t seem to find any help in documentation, blogs etc.
I’ve got a complex Tutor entity with related entity sets for Addresses, PhoneNumbers, and EmailAddresses. I’ve also got a couple other sets like Subjects and Certifications. Along with all this come foreign keys to lookup tables for things like StatusCodes, AddressTypes (like Home, Business etc), EmailTypes and so on. All this is encapsulated in an edmx in my Model project. Here’s a portion of the structure.
In Silverlight I’ve got a UserControl that is a data entry form for this tutor. I’ve created a DTO like object for the data binding to the client’s TextBox controls. All’s well till the user clicks Save.
The Save routine creates and adds a Tutor and Person objects and adds them to the DataServiceContext and links them properly. Where I’m running into trouble is that I have to add a related entity that’s ALREADY stored in the context on the database such as code tables.
For example, the person may have multiple Subject specialties: Elementary Math, Elementary Science etc. The TutorSubjectSet has to relate to 3 other sets: Subject (e.g.. Math), SubjectLevel (e.g.. Elementary) and then to the Tutor. My DTO has a list of combined Subject_With_Level items that presents a sub-set of a true Cartesian selection (there’s no such thing as Elementary (school) Calculus at least not where I went to school :-). That list shows up as a checkbox list on the UI. So, when the user clicks Save I pick up the checked items and I try to do a lookup on the combined Subject_With_Level.SubjectId and .SubjectLevelId values against the code tables that have those values.
This is where I’m lost. In a server-side function, I’d be OK because I can do those lookups in-line and get the entity immediately. In an Async situation, how do I get the related entities while I’m busy assembling the person graph? Doing an Async call in the middle of the Save process doesn’t work.
I’ve tried various things: I tried making an ad-hoc replica of the SubjectLevel using the Subject_With_Level.SubjectLevelId and attaching that to the context as follows:
```
public static SubjectLevel MakeFakeSubjectLevelFor(TutoringEntities ctx, Subject_With_Level subjectAndLevel)
{
var subjectLevel = new SubjectLevel()
{
SubjectLevelId = subjectAndLevel.SubjectLevelId,
Description = subjectAndLevel.SubjectLevel,
EffectiveDate = DateTime.Now,
EnteredBy = "",
EnteredDate = DateTime.Now,
Type = subjectAndLevel.SubjectLevel
};
try { ctx.AttachTo("SubjectLevelSet", subjectLevel); }
catch { //this tries to catch situations where the level (eg. Elementary) has already been created }
return subjectLevel;
}
```
This approach works for situations where there are no duplicates (it also has the advantage that I don’t have to do an additional call.) For example in Addresses, there will be only one Home address (I have a similar function: MakeAFakeAddressTypeFor()). You’ll notice I have a try/catch that catches the error if the items is already inserted into the SubjectLevelSet. If the item has already been inserted and I hit that error, the returned subjectLevel is not attached to the context. I get an error since the item is not being tracked. However, I can’t retrieve an existing subjectLevel without issuing an Async query against the SubjectLevelSet even if it’s in my local context.
What I'd like to do is:
```
var lev = ctx.SubjectLevelSet.Where(l => l.SubjectLevelId == subjectAndLevel.SubjectLevelId).FirstOrDefault();
if(lev == null )
lev = Helpers.MakeFakeSubjectLevelFor(ctx, subjectAndLevel);
```
but I get: "Specified method is not supported" which I assume means I have to do the query Async so I'm back to the same situation.
I’ve also tried to retrieve a list of SubjectLevels in the Loaded event delegate. That way I’d have the set of SubjectElements on hand when the Save button is pushed. Same problem, I have to issue an Async call to do a search even if I’ve got it in-hand. I tried iterating through the list for the one I needed but that gave me an error saying that the entity was not being tracked by the context.
So… clearly I’m not understanding this and am doing it wrong but I can’t find any practical examples that do this kind of thing. The how-to examples just happily load primitives into the entity to be stored. No examples that I’ve seen show related entities and how to retrieve them. I could make it simple and just store integer values for the codeId and not relate them via FK’s but that would be too much of a compromise.
Thanks for any help you can provide me.

741,293 | 1 | 741,454 | null | 2 | 2,300 | I'm attempting to make a TinyURL clone in ASP.NET MVC as a learning project.
Right now, all I want is to be able to submit new URLs to my /Home/Create action via a form.
I have my LINQ expression all setup, I have my routing setup, and I have my view setup but something is wrong with my setup.
Routing:
```
routes.MapRoute(
"Default", // Route name
"", // URL with parameters
new { controller = "Home", action = "Index" } // Parameter defaults
);
routes.MapRoute(
"Redirect",
"{hash}",
new { controller = "Home", action = "RequestLink", hash = "" }
);
```
These routes allow me to be able to go to my website, www.tinyurlclone.com/ and if nothing is passed ti will simply go to my Home/Index() action. However, if you put anything after the slash, it will consider that a Link Hash and attempt to retrieve the hash.
My HomeController is as follows:
```
[HandleError]
public class HomeController : Controller
{
TinyGetRepository repo = new TinyGetRepository();
public ActionResult Index()
{
return View();
}
public ActionResult Create(String url)
{
String hash = repo.addLink(url);
ViewData["LinkHash"] = hash;
return View();
}
public ActionResult RequestLink(String hash)
{
String url = repo.getLink(hash);
return Redirect(url);
}
}
```
My repo class has all my LINQ expressions in it for dealing with the database and I don't really need to include them because it isn't relevant to this question.
Finally, my basic Home/Index() view (used for submitting urls) is as follows:
```
<%@ Page Language="C#" Inherits="System.Web.Mvc.ViewPage" %>
<!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 runat="server">
<title>Index</title>
</head>
<body>
<div>
<center>
<span style="font-size: 14pt">TinyGet <em>(beta)</em></span><br />
<span style="font-family: Tahoma">Reduce your long links to smaller ones to keep them more memorable....<br />
</span>
<% using(Html.BeginForm("Create", "Home")) %>
<% { %>
<%= Html.TextBox("url") %>
<input type="submit" name="submitButton" value="Shorten Link!" />
<% } %>
</center>
</div>
</body>
</html>
```
However, my form simply isn't firing any methods when I click submit.
Furthermore, if I view the source of my generated HTML I can see that it didn't make my Form's action correctly, it reads:
```
<form action="" method="post"><input id="url" name="url" type="text" value="" />
<input type="submit" name="submitButton" value="Shorten Link!" />
</form>
```
Why is the HTML helper putting "" as the action when it ~should~ be putting /Home/Create? Why isn't my /Home/Create action method being called? Even if I don't use the Html helpers and specify the `<form`> tag manually it throws errors.
What is wrong here?

750,419 | 1 | 750,493 | null | 1 | 1,875 | I have two computers. One computer is an old XP and the other is a new Vista.
I have dowloaded and pretty much tested an installation of VS2008ProEdition90dayTrialENUX1435622.iso without any problems on the XP computer.
The Vista computer (where I need to do my work and where I have all the hard drive space, etc) has been pretty eventful -- in a bad way.
It seemed that the iso file, itself did not download correctly. So I did it a few times. When I ran the installer, it did some sort of file extraction on a first step (71 files, I remember) and it seemd to die on the same file.
My Vista computer has a brand new OS and a brand new hard drive. I do not understand why it is giving me so much trouble.
Eventually I resorted to FTP'ing the iso file along with all the extracted files from my XP computer to my Vista computer.
Then I managed to get further.
But it still behaves strangely.
One thing I notice is that the license agreement is missing.
That is pretty wierd.
When I get to the point where I am supposed to start the installation, the installer lights up with errors.
There are so many that I do not know where to begin.
Where do I begin?
I have tried running the iso from a virtual drive with the DAEMON toolset. That did not make a difference.
I have tried running as an Administrator. That did not make a difference.
I have tried shutting down all programs and even uninstalling anti-virus programs. That did not make a difference.
I have used the windows DVD burn utility to burn the files onto a DVD and run it from there. That did not make a difference.
And the wierdness continues. The C:\Users...\AppData\Local\Temp\dd_error_vs_procore_90.txt
has error messages that read that there is a problem copying from the F drive. Well, I do not have an F drive.
I have even gone so far is to create a virtual F drive through a network connection to myself pointing to the DVD drive.
That did not work either.
Any suggestions?
Yes, I have posted this question with the Microsoft People. I am waiting for an answer. Maybe StackOverflow can beat them.

751,840 | 1 | 752,458 | null | 5 | 15,805 | I've tried to research this on Google but there doesn't appear to me to be any coherent simple answers. Is this because it's not simple, or because I'm not using the correct keywords?
Nevertheless, this is the progress I've made so far.
1. Created 8 vertices to form 2 squares.
2. Created a texture with a 200 bit alpha value (so, about 80% transparent).
3. Assigned the same texture to each square, which shows correctly.
4. Noticed that when I use a texture with 255 alpha, it appears brighter.
The init is something like the following:
```
glClearColor(0.0, 0.0, 0.0, 0.0);
glShadeModel(GL_FLAT);
glEnable(GL_DEPTH_TEST);
glEnable(GL_CULL_FACE);
glEnable(GL_BLEND);
glBlendFunc(GL_SRC_ALPHA, GL_ONE_MINUS_SRC_ALPHA);
glPixelStorei(GL_UNPACK_ALIGNMENT, 1);
glGenTextures(1, textureIds);
glTexEnvf(GL_TEXTURE_ENV, GL_TEXTURE_ENV_MODE, GL_REPLACE);
int i, j;
GLubyte pixel;
for (i = 0; i < TEXTURE_HEIGHT; i++)
{
for (j = 0; j < TEXTURE_WIDTH; j++)
{
pixel = ((((i & 0x8) == 0) ^ ((j & 0x8) == 0)) * 255);
texture[i][j][0] = pixel;
texture[i][j][1] = pixel;
texture[i][j][2] = pixel;
texture[i][j][3] = 200;
}
}
glBindTexture(GL_TEXTURE_2D, textureIds[0]);
glTexParameterf(GL_TEXTURE_2D, GL_TEXTURE_WRAP_S, GL_REPEAT);
glTexParameterf(GL_TEXTURE_2D, GL_TEXTURE_WRAP_T, GL_REPEAT);
glTexParameterf(GL_TEXTURE_2D, GL_TEXTURE_MAG_FILTER, GL_NEAREST);
glTexParameterf(GL_TEXTURE_2D, GL_TEXTURE_MIN_FILTER, GL_NEAREST);
glTexImage2D(
GL_TEXTURE_2D, 0, GL_RGBA,
TEXTURE_WIDTH, TEXTURE_HEIGHT,
0, GL_RGBA, GL_UNSIGNED_BYTE, texture);
```
This is somewhat similar to the code snippet from page 417 in the book, , and creates a check pattern.
And then, the display function contains...
```
glClear(GL_COLOR_BUFFER_BIT | GL_DEPTH_BUFFER_BIT);
glEnable(GL_TEXTURE_2D);
// Use model view so that rotation value is literal, not added.
glMatrixMode(GL_MODELVIEW);
glPushMatrix();
// ... translation, etc ...
glBindTexture(GL_TEXTURE_2D, textureIds[0]);
glBegin(GL_QUADS);
glTexCoord2f(0.0, 0.0); glVertex3f(-1.0, +1.0, 0.0); // top left
glTexCoord2f(0.0, 1.0); glVertex3f(-1.0, -1.0, 0.0); // bottom left
glTexCoord2f(1.0, 1.0); glVertex3f(+1.0, -1.0, 0.0); // bottom right
glTexCoord2f(1.0, 0.0); glVertex3f(+1.0, +1.0, 0.0); // top right
glEnd();
// not neccecary to repeat, just good practice
glBindTexture(GL_TEXTURE_2D, textureIds[0]);
glBegin(GL_QUADS);
glTexCoord2f(0.0, 0.0); glVertex3f(-0.5, +1.0, -1.0); // top left
glTexCoord2f(0.0, 1.0); glVertex3f(-0.5, -1.0, -1.0); // bottom left
glTexCoord2f(1.0, 1.0); glVertex3f(+1.5, -1.0, -1.0); // bottom right
glTexCoord2f(1.0, 0.0); glVertex3f(+1.5, +1.0, -1.0); // top right
glEnd();
glFlush();
glDisable(GL_TEXTURE_2D);
glPopMatrix();
SwapBuffers();
```
So, this renders a 2nd square in the background; I can see this but it looks like they're being blended with the background (I assume this because they are darker with 200 bit alpha than 255 bit) instead of the texture behind...
As you can see, no transparency... How can I fix this?

Where p.Services.Id = ServicesId _

753,140 | 1 | 753,214 | null | 23 | 48,535 | Suppose there are a number of convex polygons on a plane, perhaps a map. These polygons can bump up against each other and share an edge, but cannot overlap.
To test if two polygons and overlap, first I can test each edge in to see if it intersects with any of the edges in . If an intersection is found, I declare that and intersect. If none intersect, I then have to test for the case that is completely contained by , and vice versa. Next, there's the case that ==. Finally, there's the case that share a few edges, but not all of them. (These last two cases can probably be thought of as the same general case, but that might not be important.)
I have an algorithm that detects where two line segments intersect. If the two segments are co-linear, they are not considered to intersect for my purposes.
Have I properly enumerated the cases? Any suggestions for testing for these cases?
Note that I'm not looking to find the new convex polygon that is the intersection, I just want to know if an intersection exists. There are many well documented algorithms for finding the intersection, but I don't need to go through all the effort.

I'm initializing OpenGL with
```
glViewport(0, 0, winWidth, winHeight);
glDisable(GL_TEXTURE_2D);
glEnable(GL_BLEND);
glBlendFunc(GL_SRC_ALPHA, GL_ONE_MINUS_SRC_ALPHA);

Screenshot:
That washed out dotty image should be semitransparent. The black bits are supposed to be completely transparent. As you can see, there's an image behind it that isn't showing through.
The code to generate that texture is rather lengthy, so I'll describe what I did. It's a 40*30*4 array of type unsigned char. Every 4th char is set to 128 (should be 50% transparent, right?).
I then pass it into this function, loads the data into a texture:
```
void Texture::Load(unsigned char* data, GLenum format) {
glEnable(GL_TEXTURE_2D);
glBindTexture(GL_TEXTURE_2D, _texID);
glTexSubImage2D(GL_TEXTURE_2D, 0, 0, 0, _w, _h, format, GL_UNSIGNED_BYTE, data);
glDisable(GL_TEXTURE_2D);
}
```
And...I think I just found the problem. Was initializing the full-sized texture with this code:
```
glEnable(GL_TEXTURE_2D);
glBindTexture(GL_TEXTURE_2D, _texID);
glTexImage2D(GL_TEXTURE_2D, 0, GL_RGB, tw, th, 0, GL_LUMINANCE, GL_UNSIGNED_BYTE, NULL);
glTexParameterf(GL_TEXTURE_2D, GL_TEXTURE_WRAP_S, GL_CLAMP_TO_EDGE);
glTexParameterf(GL_TEXTURE_2D, GL_TEXTURE_WRAP_T, GL_CLAMP_TO_EDGE);
glTexParameterf(GL_TEXTURE_2D, GL_TEXTURE_MAG_FILTER, GL_NEAREST);
glTexParameterf(GL_TEXTURE_2D, GL_TEXTURE_MIN_FILTER, GL_NEAREST);
glTexEnvf(GL_TEXTURE_ENV, GL_TEXTURE_ENV_MODE, GL_REPLACE);
glDisable(GL_TEXTURE_2D);
```
But I guess glTexImage2D needs to be GL_RGBA too? I can't use two different internal formats? Or at least not ones of different sizes (3 bytes vs 4 bytes)? GL_BGR works fine even when its initialized like this...

In the wiki spirit of StackOverflow, here's an update:
I spiked Joe White's IValueConverter suggestion below. It works like a charm.
I've written a "quickstart" example of this that automates the mapping of ViewModels->Views using some cheap string replacement. If no View is found to represent the ViewModel, it defaults to an "Under Construction" page. I'm dubbing this approach "WPF MVVM White" since it was Joe White's idea. Here are a couple screenshots.
The first image is a case of "[SomeControlName]ViewModel" has a corresponding "[SomeControlName]View", based on . The second is a case where the ModelView doesn't have any views to represent it. No more ResourceDictionaries with long ViewModel to View mappings. It's pure naming convention now.
I posted a download of the project here:

I read Josh Smith's [fantastic MSDN article](http://msdn.microsoft.com/en-us/magazine/dd419663.aspx) on WPF MVVM over the weekend. It's destined to be a cult classic.
It took me a while to wrap my head around the magic of asking WPF to render the .
It's like saying "Here's a class, WPF. Go figure out which UI to use to present it."
For those who missed this magic, WPF can do this by looking up the for in the ResourceDictionary mapping and pulling out the corresponding . (Scroll down to [Figure 10 Supplying a View](http://msdn.microsoft.com/en-us/magazine/dd419663.aspx)).
The first thing that jumps out at me immediately is that there's already a strong naming convention of:
```
classNameView ("View" suffix)
classNameViewModel ("ViewModel" suffix)
```
My question is:
Since the [ResourceDictionary](http://msdn.microsoft.com/en-us/library/system.windows.resourcedictionary.aspx) can be manipulated programatically, I"m wondering if anyone has managed to Regex.Replace the whole thing away, , and any new View/ViewModels get resolved by virtue of their naming convention?
[Edit] What I'm imagining is a hook/interception into ResourceDictionary.
... Also considering a method at startup that uses interop to pull out `*View$` and `*ViewModel$` class names to build the DataTemplate dictionary in code:
```
//build list
foreach ....
String.Format("<DataTemplate DataType=\"{x:Type vm:{0} }\"><v:{1} /></DataTemplate>", ...)

I've had trouble finding any material that truly explains that part of IB. Here is a screen shot to help illustrate my question.
In my screen shot of the nib window, what happens when I add the `UITabBarController` to the nib? Does that give me an instances of a `UITabBarController`?
The final part of my question is (assuming my initial assumption is correct), why would I subclass the `UITabBarController` class (in this case) instead of adding it to the nib?
