• Visual Studio 2008 (Pre-release) Creating FrameWorkElements in async calls?

  Is it possible to create a FrameWorkElement in an async call. I've tried but get an InvalidOperationException - "The calling thread must be STA, because many UI components require this" My code: public static void LoadPage() { ConstructNewPageAsync test = new ConstructNewPageAsync(ConstructPage); test.BeginInvoke(new AsyncCallback(Completed), null); } private static void ConstructPage() { Canvas c = new Canvas(); //Here i get the exception } Is there no way to throw the object over to the main-thread. In my real app it is not a canvas i'm creating but a much more complex control that inherits from canvas. It takes about 3secs to create t ...Show All

• Visual Studio Express Editions Expression evaluator

  Is there a method or function in VB Express that can, given a string like such as "5 + 3 / 4 ^ 2" evaluate it as an expression and return the result I've written RPN evaluators before, just wanted to know if I had to reinvent the wheel here... Finally found something that does this in the .NET framework... the method is found in system.data.datatable.Compute() .Compute() takes a string like "5 + 3 / 2" and evaluates to an answer. It also returns a boolean on conditionals like "5 > 3 AND 10 = 2 + 5" ...Show All

• Visual Basic Please look up the MSDN on the Lock functions and methods

• .NET Development Call client's object method/property from remote object

  Here's the scenario: - a client apps (client.exe) and a server apps (server.exe) which will run on separate AppDomain - the server host a WellKnownServiceType called MyServerObject using SingleCall mode. - the client have an instance of MyClientObject (reside on client's AppDomain) - then, the client will remotely call MyServerObject.SomeMethod() The question: - How I can modify some value inside MyClientObject (which reside on client's AppDomain) from MyServerObject which reside on the server's AppDomain I tried to pass MyClientObject as a parameter to the MyServerObject.SomeMethod(MyClientObject obj), but it don't seems to work either.

• Visual Studio Team System Shelveset manipulation

  Hi, Ever since I heard about the guantlet, I have been trying to implement a similar idea for our build/release system. I just hit a few snags. In my implementation, once a shelveset has been submitted, the shelveset must not be modified by the developers. Initially, I thought about just changing the owner -- trivial right! Not really. To do this, I had to create a workspace, unshelve the shelveset, reshelve the shelveset and finally delete the workspace. Is there an easier way to do this without unshelving the whole set Suppose I want to append a PendingChange to a shelveset (either from another shelveset or from the current workspace) assuming of course that there are no conflicts. Would I need to unshelve and then reshelve the ...Show All

• Game Technologies: DirectX, XNA, XACT, etc. Creating/Destroying an object.

  So, I was working on a new update to my game, when I realized that I have no idea how to create or destroy an object outside of the beggining of the game. I've been looking through tutorials, but so far I haven't found anything useful. Can anyone tell me how to do this, or link me to a tutorial on the subject I'd be most grateful. :D I've rarely seen an instance where you need to force the GC to do a collection. And for something like powerups, it's doubtful that you'd have so many of them that you'd need to force it. ...Show All

• .NET Development Performance Counters for 32 bit Worker Process on x64 OS???

  I would like to be able view the performance counters for ASP.NET v2.0... on my server running Windows 2003 Server Std x64.

• Visual Studio Unable to debug unmanaged C code

  Hi, I have a solution in VS2005 that comprises of a main vb.net project and an unmanaged C DLL, the linkage being via dllimport. I have my vb.net project set to allow debugging of unmanaged code and my C project set as mixed, but no matter what try I cannot get the source displayed when I step into the C DLL. Any ideas Yes, that's correct, I tried building with the pdb and setting the path for that explicitly but still no joy. It just says "exports loaded" (also, in desperation I made every single function in my code an export just so I could start to see where in the DLL it was - yep, really desperate!!) ...Show All
