怎样修改
case IDM_QU:
MessageBox (hwnd, TEXT ("今天你打卡了吗？ "),
                        TEXT ("问"), MB_OK | MB_ICONINFORMATION | MB_OKCANCEL | MB_ICONINFORMATION);
      MessageBox (hwnd, TEXT ("去打卡！ "),
      TEXT ("温馨提示"), MB_OK | MB_ICONINFORMATION | MB_OKCANCEL | MB_ICONINFORMATION);
部分来确认点的是哪个按钮（确认/取消）

你是用MessageBox上的按钮，所以可直接用它返回值来判断 

你的程序可以这样改

case IDM_QU:
if (MessageBox(hwnd, TEXT("今天你打卡了吗？ "), TEXT("问"),
MB_OK | MB_ICONINFORMATION | MB_OKCANCEL | MB_ICONINFORMATION)==IDCANCEL) //按下取消键，未打卡
{
   if (MessageBox(hwnd, TEXT("去打卡！ "), TEXT("温馨提示"),
   MB_OK | MB_ICONINFORMATION | MB_OKCANCEL | MB_ICONINFORMATION)==IDOK)
{
//按下了确定
}
 else
 {
              //按下了取消
 }
}
else
{
///确定已打卡
}
default:

另外，c语言win32的开发模式目前只适合于学习了，实际开发肯定要用C++和构件了（不然开发效率太低了）
