SetWindowContextHelpId function
Applies to: desktop apps only
Associates a Help context identifier with the specified window.
Syntax
BOOL SetWindowContextHelpId( HWND hwnd, DWORD dwContextHelpId );
Parameters
- hwnd
-
Type: HWND
A handle to the window with which to associate the Help context identifier.
- dwContextHelpId
-
Type: DWORD
The Help context identifier.
Return value
Type: BOOL
Returns nonzero if successful, or zero otherwise.

Remarks
If a child window does not have a Help context identifier, it inherits the identifier of its parent window. Likewise, if an owned window does not have a Help context identifier, it inherits the identifier of its owner window. This inheritance of Help context identifiers allows an application to set just one identifier for a dialog box and all of its controls.
