Visual Studio 2010 - Visual C++
CWnd::SetWindowContextHelpId
Call this member function to associate a help context identifier with the specified window.
BOOL SetWindowContextHelpId( DWORD dwContextHelpId );
Parameters
Return Value
Nonzero if the function is successful; otherwise 0.
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.
Example
Visual C++
// The following code fragment is from CMyDlg::OnInitDialog // CMyDlg is derived from CDialog. // Associate a help context id with the control. // IDC_TESTHELP_CONTROL is the id of the control // and HIDC_TESTHELP_CONTROL is its help context // id associated with the control. CWnd* pWnd = GetDlgItem(IDC_TESTHELP_CONTROL); pWnd->SetWindowContextHelpId(HIDC_TESTHELP_CONTROL);
