Error C000005, converting vfp 3.0 to 7.0

[JamshidNia]

i am converting a vfp 3.0 application to version 7.0 SP1. I run the convertor to convert the forms, which works fine. But i can't open/modify/run certain forms. When i try i get the fatal error C000005.
Can anyone help?

While I've never gone from VFP 3.0 to 7.0, I'm not really sure what's being "converted". Are you opening each Form separately or just opening the VFP 3.0 Project and doing a Compile All Build?

What OS are you running under? What else is running? Virus Checker? Since C0...05 is really a system error that gets past "up" to VFP, there are just too many possibilities without more information.

Is there any possibility that you could zip up a form for someone else to try? How deep is your class structure - i.e. are you just using base classes, modified base classes or some kind of framework (including the MS app gen wizards).

hello rick,
Thanks for your response. I am using VFP 7.0 SP1, Win 98. No virus software or anything else is running.

Originally when you open a 3.0 project in 7.0, it will convert it to 7.0 format. It seems that all classes/forms/etc are modified or at least the change in their dates indicates so.

I am using my own framework, the class structure is no deeper than 3 or 4 levels.

SOME forms cannot be opened/run. (fatal error C000005). I can create an exe without error, but when you run the same form using the exe, it will also crash with the same error.

I had the same problem with 6.0, and was hoping that 7.0 will resolve this issue.

Any help will be appreciated.
