Hi All,
More information. I've been stepping through the code and my application does seem to be able to connect to the file and carry out some actions. When I get to the point of executing a particular query I get the error. The query is a complicated machine generated one with 6 selects so I won't bother posting it here. Suffice to say that this query works fine with other databases from the application.

I guess what I need to know is what does the FireBird error actually mean?

Below is the data from the exception. The exception has a number of error codes associated.

Thanks for your help.
Felix
