• Windows Forms Application Failed - Invalid Manifest

  This is the first time I have actually used the Publish... function in VS .NET 2005 Beta 2, so maybe I am missing something obvious... I do the publish, and everything comes out fine, except for two warnings: C:\WINDOWS\Microsoft.NET\Framework\v2.0.50215\Microsoft.Common.targets : warning : Could not find resources for culture 'en-US'. Using culture 'en' instead. C:\WINDOWS\Microsoft.NET\Framework\v2.0.50215\Microsoft.Common.targets : warning : Could not match culture 'en-US' for item '.NET Framework 2.0 Beta'.

• Visual Studio 2008 (Pre-release) Loose XAML files with custom controls

  I have an application that will load loose XAML files with no code behind but with custom controls defined in a separate DLL. The XAML files and the DLL are not in the application's project . It's working fine when using XAMLReader but when I try to load them in a Frame by using Hyperlinks the application complains that the tags are not recognized - probably the DLL is not loaded. Is is possible to do this I believe when you reference a XAML via Frame.Source, SandboxExternalContent is "true" by default. This means a new PresentationHost instance handles it. You can set that to "false" and then declare the c ...Show All

• .NET Development Thread.Abort fixed for finally blocks?

  In .NET Framework 1.0 & 1.1, calling Thread.Abort on another thread could abort that thread while executing the "finally" part of a try/catch/finally block. That was rather nasty because it could lead to criticial resources not being released by the aborted thread. Now I see in the July CTP docs that this situation is documented as a possibility for 1.0 & 1.1 only. May be assume that this has been fixed in 2.0, and that all finally blocks will properly execute in the aborted thread, no matter when the ThreadAbortException happens Another question: ThreadAbortException can still happen in a catch block and abort the current exception ...Show All

• Game Technologies: DirectX, XNA, XACT, etc. Where can I get volume textures?

  Does anybody know where I could find some free volume textures to play around with Nico I thought of shooting lots of rays and intersecting it with an arbitrary mesh (or meshes). The DXIntersect() method is probably quite convenient for doing that. You can find out what's inside and what's outside by simply counting the hits... The user could specify the volume texture resolution. Also I like the user to be able to specify what will be inside the volume via a kind of bounding box that can be resized and rotated. Will try that when I have some free time. There are so many other things todo right ...Show All

• Visual C++ VC++ 2005 redistributable (vcredist_x86.exe etc.)

  Hi there, I noticed that the Beta 2 redistributable is hosted on the Microsoft download library, but the final ones seems not to be. Will it be hosted on microsoft.com (or is it already somewhere ). Also, it has been reported to me that on Windows 2000 the (RTM) redistributal gives an unuseful error message if Windows Installer 3.1 is not installed. The message is error 1723. "A DLL required for this install to complete could not be run." . It would be a lot more helpful to my users if this was a more informative error message - the solution of installing Windows Installer 3.1 was only found by trial and error. Thanks. ...Show All
