You have definitive answers concerning hWnd of the active control but even
were you to obtain that I don't see how it would help with your context
sensitive help.

There is a built in method as Nick mentioned but you can simulate your own
with something like

Private Sub CommandButton1_KeyDown(ByVal KeyCode As _
MSForms.ReturnInteger, ByVal Shift As Integer)
If KeyCode = vbKeyF1 Then
Call myHelp(CommandButton1.HelpContextID)
End If

End Sub

myHelp being a routine to call the help API if using html help

could do something similar with mousemove if your chm provides popups

There is also ' ActiveControl ' if needs.

Can anyone tell me the API Window Class of controls in a userform? Or,
even
better, point me to a definitive list of the window classes in MS Office?

I'm trying to find a way to to identify the hWnd of the active control
(not
easy in VBA) so I can use context sensitive help.
