ActiveX Control

[Wei]

I've managed to integrate ActiveX Controls into my application. I inserted the ActiveX Controls in my resource dialog box. If the class of the dialog box is derived from CDialog. The X Controls work fine. If the class of the dialog box is derived from CFormView (I prefer this baseclass because I want to have both dialog box and menu in the interface), the inserted ActivedX Controls don't work. What's the problem?
Thanks.
