CWnd::ShowWindow

Sets the visibility state of the window.

BOOL ShowWindow(
   int nCmdShow 
);

nCmdShow

Specifies how the CWnd is to be shown. It must be one of the following values:

  • SW_HIDE   Hides this window and passes activation to another window.

  • SW_MINIMIZE   Minimizes the window and activates the top-level window in the system's list.

  • SW_RESTORE   Activates and displays the window. If the window is minimized or maximized, Windows restores it to its original size and position.

  • SW_SHOW   Activates the window and displays it in its current size and position.

  • SW_SHOWMAXIMIZED   Activates the window and displays it as a maximized window.

  • SW_SHOWMINIMIZED   Activates the window and displays it as an icon.

  • SW_SHOWMINNOACTIVE   Displays the window as an icon. The window that is currently active remains active.

  • SW_SHOWNA   Displays the window in its current state. The window that is currently active remains active.

  • SW_SHOWNOACTIVATE   Displays the window in its most recent size and position. The window that is currently active remains active.

  • SW_SHOWNORMAL   Activates and displays the window. If the window is minimized or maximized, Windows restores it to its original size and position.

Nonzero if the window was previously visible; 0 if the CWnd was previously hidden.

ShowWindow must be called only once per application for the main window with CWinApp::m_nCmdShow. Subsequent calls to ShowWindow must use one of the values listed above instead of the one specified by CWinApp::m_nCmdShow.

See the example for CWnd::CalcWindowRect.
