>>>I don't really expect VFP to make it automatic, but just out of curiosity, did you do it by right-clicking on the classlib in the Project Manager (Other) tab, and choosing Rename? There's a teeny chance at least that project's references would then be updated.

>Thanks. I'm sure when I start working more with classes, I'll decide at some point I chose some stupid names and want to change them.

I have a production database at one site called Temptest.dbc. This was the first app I ever wrote in VFP, and I started with this dbc name, and got so far before I remembered I ought to change the name, that it became impractical.
Talk about an unfortunate name for an important file.

Maybe one saturday I'll change it.
