Using VB6 OCX in VC 7 unmanaged

I'm having a problem utilizing a control that was created in VB 6 sp6 in VC 7 (unmanged). The VC7 is a dialog based application that uses the control. The control work perfectly in a VB test form but I can not get it to work in VC7. Whenever a property is accessed a memory access exception is produced.

When I attempt to add a variable to the control I get an error saying that IExtender is not available.

Is there something I'm missing here?
