Thanks everyone

I have a VBA application with some controls on UserForm1 of ActiveX
type, lets say CircleGauge1, CircleGauge2...

I want to be able to manipulate the controls property when the
Userform is in run mode, for example changing the color of
CircleGauge1

In order to it from VB6, I need that my VB6 program ( a dll) knows how
to refer to UserForm1 and to its controls. The VB6 dll is referenced
in Excel VBA

Thanks
