添加鼠标左键按下响应函数：

1、 声明

afx_msg void OnLButtonDown(UINT nFlags, CPoint point);

2、 消息映射

BEGIN_MESSAGE_MAP(CDddDlg, CDialog)

     //{{AFX_MSG_MAP(CDddDlg)

     ON_WM_LBUTTONDOWN()

     //}}AFX_MSG_MAP

END_MESSAGE_MAP()

3、 实现函数

void CDddDlg::OnLButtonDown(UINT nFlags, CPoint point)

{

// TODO: Add your message handler code here and/or call default

PostMessage(WM_NCLBUTTONDOWN, HTCAPTION, MAKELPARAM(point.x,point.y));

CDialog::OnLButtonDown(nFlags, point);

}

4、 扩展

编写你需要响应的函数并在实现函数中加入

PostMessage(WM_NCLBUTTONDOWN, HTCAPTION, MAKELPARAM(point.x,point.y));

即可。
