MFC中有一個是DOC VIEW結構的程式（其中VIEW是繼承CFormView）在mainFrame里面有一個CDockablePane(放在底下)，CDockablePanel往上拉的程序中會出現CFromView越來越小，如何保證FormView的最小大小呢？也就是不讓CDockablePane再往上拉升

WM_GETMINMAXINFOThe WM_GETMINMAXINFO message is sent to a window when the size or position of the window is about to change. An application can use this message to override the window's default maximized size and position, or its default minimum or maximum tracking size.
WM_GETMINMAXINFO
lpmmi = (LPMINMAXINFO) lParam; // address of structure
Parameters
lpmmi
Value of lParam. Pointer to a MINMAXINFO structure that contains the default maximized position and dimensions, and the default minimum and maximum tracking sizes. An application can override the defaults by setting the members of this structure.
Return Values
If an application processes this message, it should return zero.
Remarks
The maximum tracking size is the largest window size that can be produced by using the borders to size the window. The minimum tracking size is the smallest window size that can be produced by using the borders to size the window.

那就不用停靠模式，而用浮動模式。uj5u.com熱心網友回復：

重寫虛函式virtual BOOL IsResizable() const
{
return FALSE;
}

@VisualEleven 已經試過 不行uj5u.com熱心網友回復：
CDockablePane::IsResizable()By default, dockable panes are resizable. To prevent resizing, override this method in a derived class and return FALSE. Note that a FALSE value leads to a failed ASSERT in CPane::DockPane. Use CDockingManager::AddPane instead to dock a pane within a parent frame.
Panes that cannot be resized can neither float nor enter auto-hide mode and are always located at the outer edge of the parent frame.
