I’ve developed some applications on vb3 using some3rd-party VBXs, I now want to transport thoseapplications to vb4 for enhancement. Do anyutilities exist to convert those VBXs to OCXs?
Sorry to disappoint you, but there isn’t such an animal. You’ll have to go through your VBX and make the changes to allow it to become an OCX. You’ll also have to get a 32-bit compiler that can build the OCX.
