I do not believe that MS-Access supports Database Transactions (at least not through Access97 AFAIK). MS-Access does try to provide most of the same functionality as MS-SQL Server, but there are a few areas where it falls far short... The "Access Violation" means that your program is attempting to reference memory which it is not authorized to access. This could be by referencing through a NULL pointer (you should be able to trace back to that in the debugger though). If you look at the call-stack when you get your A-V error, you can tell where the error is happening. It might be that you are passing an invalid value to a VCL function, or that you are accidentally referencing through a NULL pointer, or one of a number of other issues.
