Object does not Source Automation Events

I have a DLL that contains a .cls module plus a Form. I want the Form to be able to pass click events back to the .cls module. When I try to define the form to the Class module like this:

private withevents m_oform as frmPreview



I get a error message that says -> Object does not Source automation Events.
I have a sample program that does exactly what I am tryng to do but I can not figure out how to get it to work. Can anyone help?
The typing assistant also does not recognize "frmPreview" although in the program that works it does.

Found my own problem. You need to define the Events in the Form before it is recognized as a Automation Object.
