Creating Your First Window

Copy the following code to create you first Win32 window.

#include <windows.h>

//Define the WindowProcedure
LRESULT CALLBACK WindowProcedure(HWND, UINT, WPARAM, LPARAM);

//Define the Windows Name
char szClassName[ ] = "My First Windowl";

//Entry point of application WINMAIN
int WINAPI WinMain(HINSTANCE hThisInstance,
                   HINSTANCE hPrevInstance,
                   LPSTR lpszArgument,
                   int nCmdShow)
{
    HWND hwnd;
    MSG message;
    WNDCLASSEX wc;

    wc.hInstance = hThisInstance;
    wc.lpszClassName = szClassName;
    wc.lpfnWndProc = WinProc;
    wc.style = CS_DBLCLKS;
    wc.cbSize = sizeof(WNDCLASSEX);

    wc.hIcon = LoadIcon(NULL, IDI_APPLICATION);
    wc.hIconSm = LoadIcon(wc.hInstance, IDI_APPLICATION);
    wc.hCursor = LoadCursor(NULL, IDC_ARROW);
    wc.lpszMenuName = NULL;
    wc.cbClsExtra = 0;
    wc.cbWndExtra = 0;

    wc.hbrBackground = (HBRUSH)COLOR_BACKGROUND;

    if(!RegisterClassEx (&wc))
        return 0;

    hwnd = CreateWindowEx(
               0,
               szClassName,

               HWND_DESKTOP,
               NULL,

    ShowWindow(hwnd, nCmdShow);

    while(GetMessage(&message, NULL, 0, 0))
    {
        TranslateMessage(&message);
        DispatchMessage(&message);
    }

    return message.wParam;
}

LRESULT CALLBACK WindowProcedure (HWND hwnd, UINT message, WPARAM wParam, LPARAM lParam)
{
    switch (message)                  /* handle the messages */
    {
        case WM_DESTROY:
            PostQuitMessage (0);      
            break;
        default:                      
            return DefWindowProc (hwnd, message, wParam, lParam);
    }
    return 0;
