My ddraw program won''t quit. I hit esc to quit, it closes the window, but it is still floating in the task manager! Any ideas on what''s wrong? THX! //////////////////////////////////////////////////////////// int Game_Main(void *parms = NULL, int num_parms = 0) { if (KEYDOWN(VK_ESCAPE)) SendMessage(main_window_handle,WM_CLOSE,0,0); FillSurface(primsurf,_RGB16BIT565(0,255,0) return(1); } // end Game_Main //////////////////////////////////////////////////////////// int Game_Init(void *parms = NULL, int num_parms = 0) { InitDirectDraw(800,600,16); return(1); } // end Game_Init ///////////////////////////////////////////////////////////// //////////////FROM HEADER/CPP ENGINE FILE //////////////// ///////////////////////////////////////////////////////////// int InitDirectDraw(int width, int height, int bpp) // Creates DirectDraw and creates a double buffer { LPDIRECTDRAW ddraw1obj; DirectDrawCreate( NULL, &ddraw1obj, NULL); ddraw1obj->QueryInterface(IID_IDirectDraw4,(LPVOID *)&ddraw4obj); ddraw1obj->Release(); ddraw1obj = NULL; ddraw4obj->SetCooperativeLevel( main_window_handle, DDSCL_EXCLUSIVE| DDSCL_FULLSCREEN| DDSCL_ALLOWMODEX); ddraw4obj->SetDisplayMode(width, height, bpp, 0, 0); ShowCursor(FALSE); DDSURFACEDESC2 surfdesc; memset(&surfdesc,0,sizeof(surfdesc)); surfdesc.dwSize=sizeof(surfdesc); surfdesc.dwFlags= DDSD_CAPS || DDSD_BACKBUFFERCOUNT; surfdesc.dwBackBufferCount = 1; surfdesc.ddsCaps.dwCaps = DDSCAPS_PRIMARYSURFACE || DDSCAPS_COMPLEX || DDSCAPS_FLIP); if(FAILED(ddraw4obj->CreateSurface(&surfdesc,&primsurf,NULL))) return(0); surfdesc.ddsCaps.dwCaps = DDSCAPS_BACKBUFFER; if(FAILED( primsurf->GetAttachedSurface&surfdesc.ddsCaps,&backsurf))) return(0); width = Screen_Width; height = Screen_Height; bpp = Screen_BPP; return(1); } ///////////////////////////////////////////////////////////////// int FillSurface(LPDIRECTDRAWSURFACE4 surface, int color) { //clear out ddbltfx struct memset(&bltfxstruct,0,sizeof(bltfxstruct)); bltfxstruct.dwSize=sizeof(bltfxstruct); bltfxstruct.dwFillColor = color; if(FAILED(surface->Blt(NULL,NULL,NULL,DDBLT_COLORFILL | DDBLT_WAIT, &bltfxstruct))) return(0); return(1); } /////////////////////////////////////////////////////////////////

I assume you have a Shutdown function as well. If not, you need to make a Shutdown function which releases the surfaces and the DD object and whatever else. This could be your problem.

In your code, in WinMain, you probably have some code that looks like this:

ShowWindow(hwnd);
UpdateWindow(hwnd);

Game_Init();

while (1)
{
if (PeekMessage(&msg, NULL, 0, 0, PM_REMOVE))
{
if (msg.message == WM_QUIT) break;

TranslateMessage(&msg):
DispatchMessage(&msg);
}
Game_Main();
}
Game_Shutdown(); // add this


If you allready have a shutdown function than just ignore everything i said . Peace Out.

Then the government takes most of your profits away in taxes. So much for hard work and ingenuity :(
