Currently own understanding: Help us encapsulates WinMain, the message loop, the window procedure

    // TODO: 在此添加控件通知处理程序代码
    MessageBox(L"hello button");
}

3, the same can also add a click event for the current window

    MessageBox(L"hello current window");
    CDialogEx::OnLButtonDown(nFlags, point);
}
