Hi,

I was building with C++ Builder XE using 4.36b3 and running fine. I installed 4.37b3 and did a rebuild all. The application experiences an Access violation on 1st query. There were no other source code changes. I reinstalled 4.36b3, rebuilt, and all is well again. This is the first upgrade problem I've seen. Does it require something I may have missed?

Thanks in advance for any clues. It isn't a show stopper, but I would like to use the most current builds.

Best Regards,
Jim Shedden

Does the AV occur with an empty set of tables ?  If so, can you send me the
relevant empty tables along with the SQL that is causing the AV ?

Hi Tim,

Happy to help if I can.There are some captures and more info in the attached.

In addition, the app can run in local mode. I did have the same error.

Sorry it took me a while to get back!

Was there a particular SQL statement that is causing the AV ?  If you're
just seeing the error when trying to access a TDBISAMQuery component in
general, then most likely the issue is that you're trying to access a nil
instance of the TDBISAMQuery component.

Hi,

To troubleshoot this problem I set up another machine which did build and run 4.37 build 3 using Rad Studio XE. On the original machine I removed DBISAM with control panel and deleted any folders for it under Program Files (x86). I did the resinstall and made sure the include and library paths were correct. It seems the machine had (C++) XE in the path instead of XE (C++). Both machines now match and both build and run.

Thanks for the help.
