Using ActiveX Controls created with Visual Basic


I received an ActiveX Control witch was written in Visual Basic
(VB 5 SP3). My problem ist that if I try to include the ActiveX
Control in Borland C++ Builder I get the message that the Control is
registered, but if I go to the ActiveX Toolbar I see nothing from the
Control. If I search in Component->Install Packages I can see my
package but if I mark the package and select components, C++ Builder
shows me an emty list.
Does anybody know how to create ActiveX Controls with VB, or is there
a trick in C++ to get the components.
I only have these problems with this ActiveX Controls.
