PretranslateMessage Not Getting Called

[bitwise]

Why doesn't PreTranslateMessage(MSG* pMsg) get called from an ActiveX control when the ActiveX control is displayed in the webpage (IE)? I'm using PreTranslateMessage to display tooltips via:

BOOL CPsaSelectorCtrl:reTranslateMessage(MSG* pMsg)
{
//if the toop tip is valid
if(m_pToolTip)
m_pToolTip->RelayEvent(pMsg);
return COleControl:reTranslateMessage(pMsg);
}

Anyway, when I display the ActiveX control in the 'ActiveX Control Test Container' utility program PreTranslateMessage gets called and everything works. When I placed the ActiveX control on a webpage it DOESN'T get called and no tooltips are displayed! How could I fix this?

Thanks,

I've been working on an analogous problem, and here's what I found:

http://www.microsoft.com/mind/defau...htm&nav=/mind/0497/inthisissuecolumns0497.htm

His problem is even worded similarly to yours: "I noticed that my toolbar wasn't receiving ToolTip messages...This symptom is part of a similar illness—since the ActiveX control doesn't own the message loop, CWnd:reTranslateMessage is never called and the ToolTip messages don't get filtered properly. I'm not sure whether this is the most elegant solution, but I got around it by overriding the CToolBar::WindowProc function..."

Hope this helps.

The following will probably be a better solution. Maybe this is the only one that will work for you. It depends on your situation. I found an article that described a situation that's exactly like mine -- ActiveX control is a parent window of modeless dialog. The solution is to install a Windows WH_GETMESSAGE hook. Here's the article:
