IOleClientSite::OnShowWindow (Compact 2013)
3/26/2014
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.
