>I want to have a portion of a form that changes depending on a condition whenever refreshed. Can I create different containers as classes and then call the one I want to display somehow during runtime? I'm trying to avoid having multiple containers that will occupy the same space on my form in development. Thanks!

Yes, this seems like a reasonable approach. Use

thisform.NewObject('cntFirst','cntFirst','mylib.vcx')
     if type('thisform.cntFirst')='O'
        with thisform.cntFirst
        .left=...
        .top=...
        .visible=.t.
        endwith
     endif
