afx_msg void OnGetMinMaxInfo( LPPOINT lpPoints );
lpPoints
Points to an array of five POINT structures that contain the following information:
| Value | Meaning |
| apt[0] | This value is reserved for internal use. |
| apt[1] | Specifies the maximized width (point.x) and the maximized height (point.y) of the CWnd. |
| apt[2] | Specifies the position of the left side of the maximized window (point.x) and the position of the top of the maximized window (point.y). |
| apt[3] | Specifies the minimum tracking width (point.x) and the minimum tracking height (point.y) of the CWnd. |
| apt[4] | Specifies the maximum tracking width (point.x) and the maximum tracking height (point.y) of the CWnd. |
Called whenever Windows needs to know the maximized position or dimensions, or the minimum or maximum tracking size. The maximized size is the size of the window when its borders are fully extended. The maximum tracking size of the window is the largest window size that can be achieved by using the borders to size the window. The minimum tracking size of the window is the smallest window size that can be achieved by using the borders to size the window.
Windows fills in an array of points specifying default values for the various positions and dimensions. The application may change these values in OnGetMinMaxInfo.
This message-handler member function calls the Default member function. Override this member function in your derived class to handle the WM_GETMINMAXINFO message.
