info that might be of help-- Compiler: VC++ 6.0 Problem to do with: Win32 SDK OS: Windows XP Hi, At the moment I'm reading Sams Tricks of the Windows Game Programming Gurus, I'm just on chapter two (Actually, I got to the end of the DirectX stuff but felt I rushed through and skipped bits I didn't understand so went back to the beginning again) Anyway, I've just finished the second chapter. At the end of this chapter it gives you a little task to try. Which is to modify the code on the accompanying CD so that two windows open but make it so only one closes at a time. I made two window classes (WNDCLASSEX) winclass and winclassx, registered both and then created two windows using them. When a WM_DESTROY message is sent to my windows procedure function, I increment a global (int AmountClosed) then check, if AmountClosed == 2 then PostQuitMessage(0). However, when I close one, they both close! Has WindowsXP decided to stop programs from doing this or something?

I think I'm going to kill myself! I was doing this: [code] case WM_DESTROY: { NumberClosed++; if(NumberClosed = 2) PostQuitMessage(0); return(0); } break; [/code] I only put one = sign, and 2 is true so... I've changed it to == now. Thanks to anyone who was going to help anyway!!! :P
