Context help in CFormView?

 

 

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)

LResult + = HID_BASE_COMMAND;

}

 

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:

 

ID_SOME_MENU_ITEM_OR_COMMAND_BUTTON

IDR_SOME_WINDOW_OR_DIALOG

IDP_PROMPT

IDW_CONTROL_THAT_IS_NOT_A_COMAND_BUTTON

 

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