1、消息

2、获取消息

3、强制发送消息

Windows是一种基于消息的编程，比如鼠标左键按下，就会发送一条消息，左键弹起，也会发送一条消息。

以下做一个简单的消息处理：

实现这样的功能：当按下鼠标左键时，弹出对话框，提示按下了左键；当按下鼠标右键时，弹出对话框，提示按下了右键；

添加Windows消息处理器：

编辑代码：

void CDrawView::OnLButtonUp(UINT nFlags, CPoint point)
{
// TODO: Add your message handler code here and/or call default
AfxMessageBox("你释放了鼠标左键");
CView::OnLButtonUp(nFlags, point);
}

void CDrawView::OnRButtonDown(UINT nFlags, CPoint point)
{
// TODO: Add your message handler code here and/or call default
AfxMessageBox("你按下了鼠标右键");
CView::OnRButtonDown(nFlags, point);
}

编译并运行程序：
