Task Panel Tooltips in ActiveX control

Message Topic Search Topic Options Post Reply Create New Topic Printable Version Translate Topic

   I'm writing an MFC ActiveX control in VC++ 6.0 which has a child task panel control. Tooltips do not appear for this control, and I was able to trace it down to the fact that (1) PreTranslateMessage doesn't fire for MFC ActiveX controls (at least is the application in which my controls are embedded) and (2) even if I get it to fire, AFX_MODULE_STATE's m_pfnFilterToolTipMessage is NULL.
I also noticed the _XTP_ACTIVEX section of the CXTPTaskPanel::Create method for setting the AFX_MODULE_STATE's pfnFilterToolTipMessage to AxFilterToolTipMessage. Now, as far as I can tell, AxFilterToolTipMessage is not MFC.
So, the question is: what's the best way to get this control's tooltips to appear? Should I try to force PreTranslateMessage to fire, or just call CWnd::FilterToolTipMessage directly somewhere?

	All right. PreTranslateMessage doesn't work with ActiveX. (MFC feature) you need: Override CXTPTaskPanel and add BOOL OnWndMsg(UINT message, WPARAM wParam, LPARAM lParam, LRESULT* pResult) { MSG msg; msg.wParam = wParam; msg.lParam = lParam; msg.message = message; msg.hwnd = m_hWnd; GetCursorPos(&msg.pt); // Tooltips notification. FilterToolTipMessage(&msg); return CWnd::OnWndMsg(message, wParam, lParam, pResult); }
