windows程序设计设置重启按钮具体代码

以下是一个简单的代码示例，演示如何创建一个重启按钮：

#include <Windows.h>

// 按钮控件 ID
#define RESTART_BUTTON 101

// 窗口过程
LRESULT CALLBACK WndProc(HWND hwnd, UINT msg, WPARAM wParam, LPARAM lParam)
{
    switch (msg)
    {
    case WM_COMMAND:
        if (LOWORD(wParam) == RESTART_BUTTON)
        {
            // 重启计算机
            ExitWindowsEx(EWX_REBOOT, SHTDN_REASON_MAJOR_OPERATINGSYSTEM | SHTDN_REASON_FLAG_PLANNED);
        }
        break;

    case WM_DESTROY:
        PostQuitMessage(0);
        break;

    default:
        return DefWindowProc(hwnd, msg, wParam, lParam);
    }

    return 0;
}

// WinMain 入口函数
int WINAPI WinMain(HINSTANCE hInstance, HINSTANCE hPrevInstance, LPSTR lpCmdLine, int nCmdShow)
{
    // 注册窗口类
    WNDCLASS wc = { 0 };
    wc.style = CS_HREDRAW | CS_VREDRAW;
    wc.lpfnWndProc = WndProc;
    wc.hInstance = hInstance;
    wc.hCursor = LoadCursor(NULL, IDC_ARROW);
    wc.hbrBackground = (HBRUSH)GetStockObject(WHITE_BRUSH);
    wc.lpszClassName = "MyWndClass";
    RegisterClass(&wc);

    // 创建窗口
    HWND hwnd = CreateWindow("MyWndClass", "My Window", WS_OVERLAPPEDWINDOW,
        CW_USEDEFAULT, CW_USEDEFAULT, 400, 300, NULL, NULL, hInstance, NULL);

    // 创建重启按钮
    CreateWindow("BUTTON", "Restart", WS_VISIBLE | WS_CHILD, 150, 120, 100, 30, hwnd, (HMENU)RESTART_BUTTON, hInstance, NULL);

    // 显示窗口
    ShowWindow(hwnd, nCmdShow);
    UpdateWindow(hwnd);

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

    return (int)msg.wParam;
}

该代码使用 Windows API 创建了一个窗口，并在窗口中创建了一个名为 "Restart" 的按钮。当用户单击该按钮时，程序将使用 `ExitWindowsEx` 函数重启计算机。需要注意的是，该函数需要管理员权限才能执行。
