   TITLE     : How to Obtain Microsoft Support Files from Online Services

Many applications available today allow the user to store the size and position of the application's main window in an initialization file. The next time the user runs the application, the stored size and position information is used to create the main window. The Windows File Manager and Program Manager are examples of applications that save and restore size and position information.

Under Windows 3.0, many operations are required to retrieve the normal size and position for a window if it is maximized or minimized. Under Windows 3.1, the GetWindowPlacement() function has been provided to perform this task. GetWindowPlacement() provides the size and position of a restored window at all times, even when the window is minimized or maximized. The SetWindowPlacement() function allows an application to change its restored size and position at all times.

The GetWindowPlacement() function stores the following information regarding a specified window into a WINDOWPLACEMENT structure:

Its current state (maximized, minimized or normal).
Its maximized position.
Its minimized position.
The rectangle that the window occupies in its normal position.

The SetWindowPlacement() function restores a specified window to the state described by a WINDOWPLACEMENT structure.
