SetWindowContextHelpId info

The SetWindowContextHelpId function associates a help context identifier with the specified window.

BOOL SetWindowContextHelpId(

Parameters

hwnd

Handle to the window with which to associate the help context identifier.

dwContextHelpId

Help context identifier.

Return Values

If the function succeeds, the return value is nonzero.

If the function fails, the return value is zero. 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.
