The information in this article applies to:
  • Microsoft Windows Software Development Kit (SDK) versions 3.0 and 3.1
  • Microsoft Win32 Application Programming Interface (API) included with: 

        - Microsoft Windows NT versions 3.5 and 3.51
    - Microsoft Windows 95 version 4.0

Normally, when an application's main window is being represented by an icon ("iconic"), you can restore it to an open window by double-clicking the icon or by choosing the Restore option from the System menu.

Opening the window can be prevented by placing code into the application that processes the WM_QUERYOPEN message by returning FALSE.

If it is necessary to perform processing before the iconic window is opened, the processing should be done in response to the WM_QUERYOPEN message. After processing is complete the program can return TRUE and the window will be opened.
