SetWindowContextHelpId function

Syntax

BOOL SetWindowContextHelpId(
  HWND  ,
  DWORD 
);

Parameters

arg1

arg2

Return Value

Type: BOOL

Returns nonzero if successful, or zero otherwise.

To retrieve 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.

Requirements

   
Windows version Windows XP [desktop apps only] Windows 2000 Server [desktop apps only]

Header winuser.h
