A visual class library (a VCX file) can also be represented as a single PRG class. Each PRG (programmically created class) file would therefore be a class library -- it can contain a number of class definitions. The fact that a number of classes are contained within a single definition file (either a PRG or VCX) makes that a "library".

I am not sure if a visual class and an "equivalent" prg version would be the same for an ActiveX that requires a license for development. I believe that in this case, the two are not equivalent (the visual class contains additional data in the OLE or OLE2 fields that recognizes the license key); whereas, the prg version does not provide any of this.

>Quick question here - if I create a class programmatically (say a quit command button), can i save that class in the class library? or is it only for classes made visually?
