VC++ 2010 crashes on ShowWindow(..)

I am trying to shift my project to my other computer. I think I have the compiler set up properly. Initially, I thought it was DX causing the issue, but I narrowed it down to WinMain(..). Here is the code: int WINAPI WinMain(HINSTANCE hInstance, HINSTANCE hPrevInstance, LPSTR lpCmdLine, int nCmdShow) { HWND hWnd; WNDCLASSEX wc; ZeroMemory(&wc, sizeof(WNDCLASSEX)); wc.cbSize = sizeof(WNDCLASSEX); wc.style = CS_HREDRAW | CS_VREDRAW; wc.lpfnWndProc = WindowProc; wc.hInstance = hInstance; wc.hCursor = LoadCursor(NULL, IDC_ARROW); // wc.hbrBackground = (HBRUSH)COLOR_WINDOW; // not needed any more wc.lpszClassName = "WindowClass"; RegisterClassEx(&wc); hWnd = CreateWindowEx(NULL, "WindowClass", "Our Direct3D Program", WS_EX_TOPMOST | WS_POPUP, // fullscreen values 0, 0, // the starting x and y positions should be 0 int(SCREEN_WIDTH),int( SCREEN_HEIGHT), // set the window size NULL, NULL, hInstance, NULL); //return 0;//exits without crashing ShowWindow(hWnd, nCmdShow); return 0;//it will crash here // set up and initialize Direct3D GameEngine.initD3D(hWnd,hInstance); //init the environment here. // enter the main loop: UINT ExitMessage=GameEngine.MainLoop(); return ExitMessage; } Notice the 2 return lines arround ShowWindow(..)? That's how I came to the conclusion it had something to do with showing the window. I believe it's the creation that's actually causing the problem, but I don't know what could cause it to work on one machine and not another. Perhapse I don't have the correct SDK (VC) or I don't have my compiler set up correctly????

I don't have the code that isn't working. I moved all my files into another project and I got it to work. That's actually funny: the "solution" was the "problem"....

That sounds like you should learn about using a version control system to not loose code. Mercurial(hg) would be easiest to learn, but git is also widely used. (Even if you dont want to learn one of those at least start with the poor mans "version control" of copying the whole folder every time before you change anything and number those by date.)
