ActiveX Control - retreiving values

I would like some info on the following :
On creating a customised dialog box using the standard toolbar
controls (like DirList,DriveList and FileList) in an ActiveX control,
how do I expose the value of the filename for example in the developer
form? Should I use a method or an event and how should the code read in
both the control as well as the container form ?
Thanks

IMHO you should expose the filename as a property, not a method or event.
(and, I don't understand the second part of your question)
