Win 8.1 + FB 2.5 server + FBClient_2.1 - I can do?

[louis]

Hallo,
I have a program created by D5 with Zeos 6.6.6 stable that use FB 2.1 protocol.
Now this program must run on Win 8.1 and in this PC is installed FB 2.5 (is not possible to install version 2.1 is prohibited by the owner).
I tried the program with FBClient 2.5 and I have many AccessViolation. If I install FBClient 2.1 in same dir of a program seem to work.

Can anyone confirm that this scenario (to use FB 2.5 server from FBClient 2.1) is possible? What problems I expect?

Thanks.

Hello louis

usually you can do this. I am not 100% sure, this scenario is oficially supported by the firebird team but for the usual cases it works. There are some cornerecases that seem to give problems nonetheless. Like comparing the contents of environment variables that contain umlauts with fields in the database. So in general I suggest to upgrade your appliction as soon as possible to Zeos 7.1 and so at least to Delphi 7.
Best regards,

Jan

Ok, thanks marsupilami, I'm already rewriting the application with D2010 but it is not ready yet, unfortunately with the transition to unicode some components are difficult to update, in the meantime, I try to make it work with FB 2.5.

Thanks and, Happy New Year
