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)
returnHTCLIENT;
returnret;
}
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)
returnHTCLIENT;
returnret;
}
