I am trying to work with some forms by Andy Kramek from Southwest Fox 2005 where he presented an updated version of his DataClass that was originally published in "MegaFox".

My problem is if I run the demo from SWfox2005 in VFP7 I get the 1744 error. If I move Andy's new classes into the MegaFox project and run it from VFP7 I get the same error.

Obviously the new classes break something in the form but what I don't understand is why do the SWFox2005 forms break when they run in VFP7?

I am not asking for a debug, what I am trying to understand is what changed between VFP7 and VFP9 that makes it so new forms can't go back? Was the change in VFP8 or VFP9?

Thank you.
