>I've built a simple text box validation OCX. Its in the DB programming in VB5 in 21 days. After compiling the OCX. I made some changes to the OCX and I attempted to bring the form back. At this time it said "Version 2.9 of c:\vbTest\CUSTOMERVALIDATION.OCX is not registered. The control will be upgraded to version 4.0."

If you open your ActiveX control project and your client application project in the same instance of VB (only one copy in memory containing both project at the same time) you should not have any problem.

If you do not open your client application at the same time as your ActiveX control, recompiling it re-register it.
