>>Has anyone encountered problems when mingling vfp7 and vfp9 startups using the same sources? I mean, does vfp9 change any code and thus make it incompatible with older versions? I'm not referring here to the explicit and conscious use of new functions/commands.
>>
>>So far, I've used vfp9 on a copy of vfp7 sources. Now I don't want to do that anymore. Instead, I want to start vfp9 in the vfp7 code environment. Can I expect problems?

  • DO not share foxuser.dbf between VFP7 and VFP9 or you may encounter strange problems.

  • VFP9 allows property values to exceed 255 charcters. Classes/Forms with such properties cannot be open in VFP7. In particular, watch out for _MemeberData property which is updated by Class/Form Designer implicitly.

    Will _memberdata be an 'innocent' property as long as I don't use it?

    Constructive frustration is the breeding ground of genius.
    If there’s no willingness to moderate for the sake of good debate, then I have no willingness to debate at all.
    Let's develop superb standards that will end the holy wars.
