>is there a way to add the VFP listbox control to the VB.NET form? or is there a way to convert the VFP listbox control to an ActiveX control so I can add it to the VB.NET form?

No, you can't use VFP controls in other tools because they aren't real controls. They're bitmaps. You can't convert them either.

FYI.. you don't want to use ActiveX controls in .Net. You CAN create your own controls under .Net. I haven't done it yet, but it can be done.
