If I write a script component I can give it a version, and from an ASP page I use <BR><BR>set smthing = server.createobject("something.class.1.00") <BR><BR>How can I do this in a VB ActiveX dll? <BR>I set the version in the project properties, but when I call the object I get an error saying "Invalid Class string". <BR><BR>Any Ideas on getting around this?
