如何禁止改变对话框的大小？

[wangdeqie]

禁止通过拖动对话框改变其大小！
1.不要告诉我设置对话框的Styles属性，我要通过写代码控制。
2.告诉我该用什么函数的同时，请补全相应的参数！初学mfc，很菜！
3.收到有效代码，立马结帐给分！
先谢过了！

msdn

GetWindowLong
SetWindowLong

classwizard里面添加WM_NCHITTEST消息的映射函数，修改如下即可
(提示默认的classwizard里面找不到该消息，在class info里面message filter里面选中window就有了)

UINT CTempDlg::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)
return HTCLIENT;

return ret;
}

Dialog程序用这个函数就可以了，详细地info可以查msdn了，呵呵!
ModifyStyle(去掉的窗口类型,增加的窗口类型,窗口的位置和大小是否修改);

ModifyStyle(WM_THICKFRAME,WM_DLGFRAME,0);

This method modifies a window style. Styles to be added or removed can be combined by using the bitwise OR (|) operator. For more information about the available window styles, see CreateWindow.

BOOL ModifyStyle(
DWORD dwRemove,
DWORD dwAdd,
UINT nFlags = 0 );
Parameters
dwRemove
Specifies window styles to be removed during style modification.
dwAdd
Specifies window styles to be added during style modification.
nFlags
Flags to be passed to SetWindowPos, or zero if SetWindowPos should not be called. The default is zero. See the Remarks section for a list of preset flags.

你好！gaohl
1.报错：syntax error : '|'
2.HTTOP == ret ret ¦ ¦ HTBOTTOM == ret ¦ ¦ HTLEFT == ret ¦ ¦ HTRIGHT == ret 这个是禁止改变大小的吗？
HTBOTTOMLEFT == ret ¦ ¦ HTBOTTOMRIGHT == ret ¦ ¦ HTTOPLEFT == ret ¦ ¦ HTTOPRIGHT == ret 这个是禁止移动的吗？

To na_he ：
ModifyStyle，我试了，不行！我这个对话框比较特殊，是作为改变通用对话框的模板对话框！

哦，你用|就不报错了，呵呵

用ModifyStyle把WS_SIZEBOX和WS_MAXIMIZEBOX风格去掉就行啦
