Perhaps someone knows the answer to these.

1) If I create an ActiveX control using VB6, can I use it in a VC6 project?

2) If the answer to 1 is 'Yes', are there any special precautions I need to be aware of?

I have a VC6 program that I wrote back in 2003 that is an embeddable OLE program that I need to rewrite and there are also some
standalone VB apps that would need to share the same controls. I'm hoping I don't have to develop the controls in VC6 because I've
never had to do that before and the time constraints on the project are fairly tight.

Yes. ActiveX is ActiveX; it is not tied to VB.

Dunno, but I strongly suspect the answer is No.

I haven't been able to find many references on using an ActiveX control developed in VB in VC6. One article I read said something
to the effect that "an AxtiveX control can be used in any application that supports ActiveX, although there are implementation
differences." No additional explanation.

I guess I was hoping somebody might have done this before and could offer some insight. For example, do you have to provide
property pages in order to configure the control within VC6?

Since I don't seem to be finding a lot of info via Google, I thought someone here might have some first hand knowledge and
experience.

Thanks, Jeff.

I would guess it's not a very common thing to do. For one, I would suspect that very few C++ developers are going to want to make
the VB6 runtime (and any other dependencies the ActiveX component might have) a requirement for their C++ program.

But other than the runtime requirement, as Jeff said, it's irrelevant what language was used to develop the ActiveX control. You'd
use it in VC++6 just the same as if the ActiveX control were written using VC++6 instead of VB6. So, maybe your search is too
limited if you're including in your search that it's a VB6-authored control.

Thanks, Mike. Maybe I'm worrying about something without cause. I just wanted to make sure that I don't get into a situation late
in the project where I say "Jee, I wish I had know that before I started down this path."
