• Game Technologies: DirectX, XNA, XACT, etc. about get color value

  I just want to get a pixel's color value. In openGL ,I know a function,is:glReadPixel(...); How to use D3D implent same function I'm not sure I fully understand you... I've only written a couple of OpenGL programs (years ago!) so I don't really know anything about glReadPixel()! If you want to read, at a given pixel, from the depth buffer then it's more tricky - for performance reasons it's best not to mess with it. By design, you have to be using a lockable depth buffer (e.g. D3DFMT_D16_LOCKABLE) to gain access - attempting to read the other (more common) formats will fail. hth Jack ...Show All

• Windows Forms Icon of the Application Reference in the Start menu

  The icon of the Application Reference in the Start menu is a default icon (white and blue empty window icon), not the actual icon of the .exe file for my application. How can I fix that The icon for my application is stored in a Win32 resource embedded in my .exe file (that's option "Resource File" in the Application tab of the project properties). I chose to do that because it was an easy way to pack several icons to implement a file association mechanism.     Jerome, The ClickOnce runtime requires that the icon file be a separate file (not embedded).

• .NET Development FK violation on TableAdapter.Update

  I have 2 tables, namely Parent(ParentID, ParentName) and Child(ChildID, ChildName, ParentID). I created a form by dragging the datasources based on the dataset produced by this tables. The Parent table is represented by details while the Child is with DataGridView. The Child table bindingsource is bound to the relationship between the two tables so I expected that Child.ParentID would change accordingly after updating the parent table to the database. To my surprise, it didnt and throws an exception about FK violation!

• Visual C# C# analog clock runs slow on some computers

  Hi all, I have a problem with the System.Threading.Timer class that I am using for my clock. The clock runs faster on an Intel box than it does on an AMD box and it has nothing to do with the CPU speed. Has anyone come across this before Any suggestions would be much appreciated. Ok, I have found that it is not a cpu problem as I have another box with an AMD Duron XP 1000MHz(5x200) which runs at the correct speed. I have tried it on another computer (an intel celeron 4A, 2400MHz(6x400) and it runs slow. ) There doesn't seem to be any link between the CPU and the slow clock problem. I thought now maybe it could be a video card problem, but ...Show All
