Problem bringing up a window in Win32

Daaark · 2001-08-04T20:02:25

I keep copying out the first program in the WINDOWS GAME PROGRAMMING FOR DUMMIES BOOK, and whenever I compile, the program ends right away instead of showing a window!!! Can someone tell me what's wrong? #define WIN32_LEAN_AND_MEAN #include #include #include #include #define WINDOW_CLASS_NAME "WNDCLASS1" HWND main_window_handle = NULL; LRESULT CALLBACK WindowProc(HWND hwnd, UINT msg, WPARAM wparam, LPARAM lparam) { PAINTSTRUCT ps; HDC hdc; switch(msg) { case WM_CREATE: { return(0); } break; case WM_PAINT: { hdc = BeginPaint(hwnd,&ps); EndPaint(hwnd,&ps); return (0); } break; case WM_DESTROY: { PostQuitMessage(0); return(0); } break; default :break; } return(DefWindowProc(hwnd,msg,wparam,lparam)); } int WINAPI WinMain(HINSTANCE hInstance, HINSTANCE hPrevInstance, LPSTR lpCmdLine, int nShowCmd) { WNDCLASS winclass; HWND hwnd; MSG msg; winclass.style = CS_DBLCLKS | CS_OWNDC | CS_HREDRAW | CS_VREDRAW; winclass.lpfnWndProc = WindowProc; winclass.cbClsExtra = 0; winclass.cbWndExtra = 0; winclass.hInstance = hInstance; winclass.hIcon = LoadIcon(NULL,IDI_APPLICATION); winclass.hbrBackground = (HBRUSH)GetStockObject(BLACK_BRUSH); winclass.lpszMenuName = NULL; winclass.lpszClassName = WINDOW_CLASS_NAME; if (!RegisterClass(&winclass)) return 0; if (!(hwnd = CreateWindow(WINDOW_CLASS_NAME,"TEST",WS_OVERLAPPED |WS_VISIBLE, 0,0,320,200,NULL,NULL,hInstance,NULL))) return(0); main_window_handle = hwnd; while(1) { if(PeekMessage(&msg,NULL,0,0,PM_REMOVE)) { if(msg.message == WM_QUIT) break; TranslateMessage(&msg;; DispatchMessage(&msg;; } //main game processing goes here } return(msg.wParam); } I hope that formats right --------- |GOT MALK?| --------- Edited by - felisandria on August 2, 2001 11:07:34 AM

For now, can I just try the DX stuff, and paste it in the premade basic windows app you get when you pick it from start a new project?

I don''t know which "DX stuff" you mean. It might even work if it''s based on the same basic app.
My suggestion would be trying to blit some bitmaps and put some pixels to the window (lookup BitBlt and SetPixelV) using standard GDI functions. Then create some sort of demo so yo can get experience with graphics/game programming in general before moving to something complex and confusing (especially for a beginner, like me

like DX

I''m that much of a newbie!

I''ve made games before!

I''ve made some text based RPGs, a LORD2(old bbs door game) clone and a 320x200 tile based rpg game in Qbasic.

And I had a working 320x200 tile based rpg game engine in C (djgpp/allegro)

I wanted to try and get one of my screen savers I made. How hard is it to set up a screen, and blit bitmaps with DX?

Sorry, but I haven''t done much DX myself. Take a look at the "Game Programming Genesis"-Tutorials (if you haven''t already)in the resources area. There''s a nice step by step guide to Direct Draw. Shouldn''t be that hard.
