IOleClientSite::OnShowWindow

A version of this page is also available for

Windows Embedded CE 6.0 R3

4/8/2010

This method notifies container when an object becomes visible or invisible.

Syntax

HRESULT OnShowWindow( 
  BOOL fShow
);

Parameters

• fShow
  [in] Boolean value that is set to TRUE if an object's window is open, or set to FALSE if it is closed.

Return Value

This method supports the standard return values E_FAIL and E_UNEXPECTED, as well as the value S_OK that indicates that shading or hatching has been added or removed.

Remarks

An embedded object calls OnShowWindow to keep its container informed when the object is open in a window. This window might or might not be visible to the user.

The container uses this information to shade the object's client site when the object is displayed in a window, and to remove the shading when the object is not.

A shaded object, having received this notification, knows that it has an open window and therefore can respond to being double-clicked by bringing this window to the top, instead of launching its application to obtain a new one.
