Allan,

I would hazard a guess at header corruption, and yes you can sometimes open a table even when it is corrupted

I would try re-building the affected tables and indexes
Also get rid of the Foxuser.*

But remember.. backup first!

>One of the users of our software is receiving the C5 error while running a day-end function that appends records from a 'daily' table to an 'archive' table. We know that the error is occuring in a small block of code where few simple append from commands are being executed.

>Here is some background info. This particular credit union is running this system on Windows 98 PC's - with the database, tables, and executable residing on their Novell Server. They have run the day-end function approximately 200 times with no problems (as have about 25 other sites) since the app was put into production. A few days ago, the user that ran the day-end function had her old, cranky PC freeze during the day-end routine (she had been experiencing decreased performance with this old box for a while). So, they turned the power off.

>I think the C5 error may have something to do with problems with the Archive table caused when the day-end process was terminated by the user. However, they are able to physically open all the tables used by the app without receiving any error messages. Can a corrupt table be opened without receiving an error message?
