Hi Folks! I''ve got a problem. Is this code correct to create a basic window like it is said in the book "Tricks of Windows Game Programming Gurus": #define #include #include #include //Defínes #define WINDOW_CLASS_NAME "WINCLASS1" //Functions LRESULT CALLBACK WindowProc(HWND hwnd, UINT msg, WPARAM wparam, LPARAM lparam) { PAINSTRUCT ps; HDC hdc; //what is the maessage switch(msg) { case WM_CREATE; { //do initialization stuff here //return success return(0); } break; case WM_PAINT: { //simply validate the window hdc = BeginPaint(hwnd,&ps); //you would do all your painting here EndPaint(hwnd,&ps); //return success return(0); }break; case WM_DESTROY: { //kill the application, this sends a WM_QUIT message PostQuitMessage(0); //return success return(0); }break; default:break; } // end switch //process any messages that we didn''t take care of return (DefWindowProc(hwnd, msg, wparam, lparam)); } // end WinProc //Winmain int WINAPI WinMain(HINSTANCE hinstance, HINSTANCE hprevinstance, LPSTR lpcmdline, int ncmdshow) { WNDCLASSEX winclass; HWND hwnd; MSG msg; //first fill in the window class structure winclass.cbSize = sizeof(WNDCLASSEX); winclass.style = CS_DBLICKS | 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.hCursor = LoadCursor(NULL, IDC_ARROW); winclass.hbrBackground = GetStockObject(BLACK_BRUSH); winclass.lpszMenuName = NULL; winclass.lpszClassName = WINDOW_CLASS_NAME; winclass.hIconSm = LoadIcon(NULL, IDI_APPLICATION); //register the window class if (!RegisterClassEx(&winclass)) return(0); //create the window if (!(hwnd = CreateWindowEx(NULL, WINDOW_CLASS_NAME, "Grundfenster", WS_OVERLAPPEDWINDOW | WS_VISIBLE, 0, 0, 400, 400, NULL, NULL, hinstance, NULL))) return(0); //enter main event loop while (GetMessage(&msg,NULL,0,0)) { //translate any accelerator keys TranslateMessage(&msg); //send the message to the window proc DispatchMessage(&msg); } // end while //return to Windows like this return(msg.wParam); } If i want to run it, there is always fatal error C1010! Please help me! Thanks!!

oops. Just saw the post on how you can''t type in the includes on this forum properly! Forget the second part of my message above then.

You will need to add 2 functions after creating the window, it is:

ShowWindow(hwnd, cmd_show);
UpdateWindow(hwnd);

Or something similar (can''t remember off hand the parameters, but look those 2 functions up in help)...

Doh! You are getting linker errors...

When setting up your project you must specify a "win 32 application"...

Then copy/paste the code into the project and it should compile. It appears you are missing some compiler directives, and specifying the project as win32 application should fix that.
