I was programming the example code from Frank Luna's book "Introduction to 3D Game Programming with DirectX 10". The code is the first Win32 example in the Appendix A: Windows Programming section.

Right now, the program compiles under both VC++ 2008/2010, but no window appears, although the debug session has started and I have to forcefully close it. I have no idea where it is, I'm not using Win32 Console mode, I have closed all other windows and no other IDE or session of VC++ is running.

Any idea why this might be happening?

PS: I have also checked my Processes. It is indeed running.
