minimized

SIZE_MAXSHOW Another window, other than this one, has been restored from

being maximized or minimized

The cx argument specifies the new width of the client area of the window

The cy argument specifies the new height of the client area of the window.

To use this message, you should first call its implementation in the parent class before

implementing the behavior you want. This can be done as follows:

void CAnyWindow::OnSize(UINT nType, int cx, int cy)

{

CParentClass::OnSize(nType, cx, cy);

// TODO: Add your message handler code here

}

WM_SIZING: While the user is changing the size of a window, a message called

ON_WM_SIZING is being sent. Its syntax is:

afx_msg void OnSizing(UINT nSide, LPRECT lpRect);

When a user is resizing a window, he or she typically drags one of the borders or corners

on a direction of his or her choice. The first argument, nSize, indicates what edge is being

moved when resizing the window. It can have one of the following values:
