重写CWnd :: OnGetMinMaxInfo.请参见此处 [

Override CWnd::OnGetMinMaxInfo. See here[^] for a whole discussion about it.

完成！非常感谢.

但是我有更改限制.

Done !! Thanks a lot.

But i have change limit.

lpMMI->ptMinTrackSize.x = 1000; 
lpMMI->ptMinTrackSize.y = 700;

代替

in place of

lpMMI->ptMaxTrackSize.x = 1000; 
lpMMI->ptMaxTrackSize.y = 700;

我做了此更改是因为我确实想阻止用户将大小从最大调整为最小.不是从最小到最大.

I have done this change because i do want to stop user from resizing from maximum to minimum. not from minimum to maximum.

对不起:)

Sorry :)
