Load VB ActiveX from Delphi

I'm not sure if this is the right place for this question/problem.


I have created a simple ActiveX control that contains a label and a timer and calls some API functions.

I gave it to a friend of mine, who makes programs in Delphi, for testing.
Although it appears in the list of ActiveX controls (the file is properly registered), he can't import it, because an error message appears after selecting the control: "3D1 is not a valid name."

Does this mean that he can't use VB ActiveX in Delphi?

Btw, the control works flawlessly in VB.
