Context help in CFormView?

Source: Internet
Author: User



I wantThe CFormView class SDI application adds real context help, but fails.

A: You should overload the OnHelpHitTest function of the CMyFormView class:



LRESULT CMyFormView: OnHelpHitTest (WPARAM, LPARAM lParam)


LRESULT lResult = (LRESULT) 0x00;


CWnd * pWndChild = ChildWindowFromPoint (Cpoint (lParam), CWP_ALL | CWP_SKIPINVISIBLE );


If (pWndChild &: IsWindow (pWndChild-> m_hWnd ))


LResult =: GetWindowLong (pWndChild-> m_hWnd, GWL_ID );


If (lResult)




If (lResult = (LRESULT) 0x00)

LResult =: GetWindowLong (m_hWnd, GWL_ID) + HID_BASE_RESOURCE;


Return lResult;



Then you can use the help files you usually use.To ensure the correct prefix, see TN028: Context-Sensitive Help Support.

For example:







Make sure thatID is included in the file resource. hm.
