SetWindowContextHelpId function (winuser.h)
Associates a Help context identifier with the specified window.
Syntax
BOOL SetWindowContextHelpId(
HWND unnamedParam1,
DWORD unnamedParam2
);
Parameters

A handle to the window with which to associate the Help context identifier.
unnamedParam2

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.
