一、禁止對話框的移動
(1)、第一種方法 為這個對話框添加系統消息過慮處理： .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)、第二種方法 .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、禁止對話框改變大小 .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語句的前兩行是用來禁止改變大小的，最后一行是用來禁止移動的
if(HTTOP == ret || HTBOTTOM == ret || HTLEFT == ret || HTRIGHT == ret || HTBOTTOMLEFT == ret || HTBOTTOMRIGHT == ret || HTTOPLEFT == ret || HTTOPRIGHT == ret || HTCAPTION == ret)
return HTCLIENT;
return ret;
}
