I want to subclass a TextBox so that it can create an EditBox on the fly. I need the child EditBox to be able to read and write the parent TextBox properties.

In VFP, it's single inheritance---so a textbox subclassed will always be a textbox. A textbox can't become an editbox or label or form, etc. An editbox subclassed is an editbox. I had written some easy PRGs showing how inheritance worked about 10 years ago for Central PA Visual Foxpro User Group...I'll see if I can find them (but I doubt it). The help manual isn't bad, and of course Hentzenwerke.com's catalog of VFP books is 2nd to none in that regard. _______________________________________________ Post Messages to: [email protected] Subscription Maintenance: http://leafe.com/mailman/listinfo/profox OT-free version of this list: http://leafe.com/mailman/listinfo/profoxtech Searchable Archive: http://leafe.com/archives/search/profox This message: http://leafe.com/archives/byMID/profox/[email protected] ** All postings, unless explicitly stated otherwise, are the opinions of the author, and do not constitute legal or medical advice.
