Subject AW: [firebird-support] Re: Backup Restore problem
Author Christian Waldmann
Hello Mauleen

If an exception is thrown, there is reported in what program context the exception was thrown. This information you have already posted.

But within the thrown exception, there is an exception code or even an exception message. If you catch the exception in the application, this info can be printed out, or examined in the debugger.

And here some other tips:

To replace the database during restore, all users must be logged out. Maybe even VS has a connection open. Be sure that no user are logged in.

Good programming

P.S: I hope this brings the thread back to friendly, constructive conversation :-)




I clearly mention my error message. which was written in the post. you just read the post properly.
