SetWindowContextHelpId

Associates a Help context identifier with the specified window.

Syntax


BOOL SetWindowContextHelpId(
    HWND hwnd,              
    DWORD dwContextHelpId   
);

Parameters

hwnd
Handle to the window with which to associate the Help context identifier.
dwContextHelpId
Help context identifier.

Return Values


Returns nonzero if successful, or zero otherwise.

To get extended error information, call GetLastError.

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.
