Seems like something is wrong with your query. Post the source code that is giving you error. My immediate guess would be that com.ExecuteNonQuery() is giving an error.

I once got this exception when the database was read-only (Access). Making it writable again solved the problem.

Thanks everybody,
I attached three sample files I used...
If you can run without error, then my machine may be wrong...
If you can't also run, then my code may be wrong...
