如何更改C++中的MessageBox位置

int MessageBox(
  HWND hWnd,
  LPCTSTR lpText,
  LPCTSTR lpCaption,
  UINT uType
);

#include <windows.h>

int WINAPI WinMain(HINSTANCE hInstance, HINSTANCE hPrevInstance, LPSTR lpCmdLine, int nCmdShow)
{
    // 获取屏幕尺寸
    int screenWidth = GetSystemMetrics(SM_CXSCREEN);
    int screenHeight = GetSystemMetrics(SM_CYSCREEN);

    // 创建一个临时的隐藏窗口来获取 MessageBox 的尺寸
    HWND hWnd = CreateWindowEx(0, "STATIC", NULL, WS_POPUP | WS_VISIBLE, 0, 0, 1, 1, NULL, NULL, hInstance, NULL);
    RECT rect;
    GetWindowRect(hWnd, &rect);
    int msgBoxWidth = rect.right - rect.left;
    int msgBoxHeight = rect.bottom - rect.top;
    DestroyWindow(hWnd);

    // 计算消息框位置
    int x = 0; // 左上角 x 坐标
    int y = 0; // 左上角 y 坐标

    // 显示消息框
    MessageBox(NULL, TEXT("Hello, World!"), TEXT("Message"), MB_OK | MB_ICONINFORMATION);

    return 0;
}
