如何为Windows编写一个非常简单的原生应用程序(不需要.NET和安装过程)

#include <windows.h>

// 窗口过程函数
LRESULT CALLBACK WndProc(HWND hwnd, UINT msg, WPARAM wParam, LPARAM lParam) {
    switch (msg) {
        case WM_DESTROY:
            PostQuitMessage(0);
            break;
        default:
            return DefWindowProc(hwnd, msg, wParam, lParam);
    }
    return 0;
}

int WINAPI WinMain(HINSTANCE hInstance, HINSTANCE hPrevInstance, LPSTR lpCmdLine, int nCmdShow) {
    const char* CLASS_NAME = "SampleWindowClass";

    // 注册窗口类
    WNDCLASS wc = {};
    wc.lpfnWndProc = WndProc;
    wc.hInstance = hInstance;
    wc.lpszClassName = CLASS_NAME;

    RegisterClass(&wc);

    // 创建窗口
    HWND hwnd = CreateWindowEx(
        0,                              // 扩展样式
        CLASS_NAME,                     // 窗口类名
        "Simple Window",                // 窗口标题
        WS_OVERLAPPEDWINDOW,            // 窗口样式
        CW_USEDEFAULT, CW_USEDEFAULT,   // 窗口位置
        CW_USEDEFAULT, CW_USEDEFAULT,   // 窗口大小
        NULL,                           // 父窗口
        NULL,                           // 菜单
        hInstance,                      // 实例句柄
        NULL                            // 附加参数
    );

    if (hwnd == NULL) {
        return 0;
    }

    ShowWindow(hwnd, nCmdShow);

    // 消息循环
    MSG msg = {};
    while (GetMessage(&msg, NULL, 0, 0)) {
        TranslateMessage(&msg);
        DispatchMessage(&msg);
    }

    return msg.wParam;
}
