I've started trying to learn how to use HLSL, but my programs have problems running. Whenever I try to run the program, the name and icon pop up on the toolbar like it's working, but then it just hangs there. It shows the compiler but I can't click on it. I have to alt+tab out of the program and close it from there to get rid of it. I'm using Visual C++ 2008 and if it's of any importance, the tutorial I'm using is in the shader section of www.directxtutorial.com, the first lesson of that section. Any help or suggestions would be greatly appreciated.

Can't you run the code in debug mode and step through in the debugger until you reach the point where I begins to hang?

Set a breakpoint somewhere in the code, and then you can step through line by line with F10 and F11 (F11 will go into function calls, F10 won't). You can also break into the debugger at any point, but you'll have to get focus back to VS through alt-tab or whatever.

Ok I did that and it showed me the line


effect->FindNextValidTechnique(NULL, &technique);


And when I looked at the pointer technique, it give me the error "CXX0030: Error: expression cannot be evaluated);"

A D3DXHANDLE isn't a pointer, even though it probably is typedef'ed to a C pointer type. Therefore when the debugger looks at it it thinks it's a pointer and tries to dereference it, but being a handle it doesn't actually point to readable memory.
