>Is this normal that a VB ActiveX does not show its properties in the property sheet of the ActiveX in Visual FoxPro while I can see them in VB? Is it because only ActiveX built in C++ can offer that?

Have you tried right clicking on the object and then select properties. I have not built any of my on activeX with VB but have seen properies from outside sources that only display with this method.
