MFC禁止改变窗口大小和移动窗口

一、禁止对话框的移动

(1)、第一种方法 为这个对话框添加系统消息过虑处理: .h中:

afx_msg void OnSysCommand(UINT nID, LPARAM lParam);

... .cpp中

BEGIN_MESSAGE_MAP(CXXXDlg, CDialog)

... ON_WM_SYSCOMMAND()

... END_MESSAGE_MAP()

void CXXXDlg::OnSysCommand(UINT nID, LPARAM lParam)

{

   if (nID == SC_MOVE || nID==0xF012)

     return;

  else

   CDialog::OnSysCommand(nID, lParam);

}

SC_MOVE就是0xF010。

(2)、第二种方法 .h中: ...

afx_msg UINT OnNcHitTest(CPoint point);

... .cpp中

BEGIN_MESSAGE_MAP(CXXXDlg, CDialog)

... ON_WM_NCHITTEST()

... END_MESSAGE_MAP()

UINT CXXXDlg::OnNcHitTest(CPoint point)

{

   int ret = CDialog::OnNcHitTest(point);

   if( HTCAPTION == ret)

     return HTCLIENT;

  return ret;

}

二、禁止对话框改变大小 .h中:

... afx_msg UINT OnNcHitTest(CPoint point);

... .cpp中 BEGIN_MESSAGE_MAP(CXXXDlg, CDialog)

... ON_WM_NCHITTEST()

... END_MESSAGE_MAP()

UINT CXXXDlg::OnNcHitTest(CPoint point)

{

  int ret = CDialog::OnNcHitTest(point);

   //if语句的前两行是用来禁止改变大小的,最后一行是用来禁止移动的

   if(HTTOP == ret || HTBOTTOM == ret || HTLEFT == ret || HTRIGHT == ret || HTBOTTOMLEFT == ret || HTBOTTOMRIGHT == ret || HTTOPLEFT == ret || HTTOPRIGHT == ret || HTCAPTION == ret)

   return HTCLIENT;

return ret;

}
