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;
}
