This is .net code, so you should be asking in a .net group. They have
"aspnet" in their names.

But, before doing that, make sure your aspnet account has NTFS permissions
to modify the directory that your MDB file exists in.

Also, it's not "DELETE * FROM table..." It's just "DELETE FROM TABLE....

Not with Access ... the * is required in JetSQL.

Not with Access ... the * is required in JetSQL.

I thought that was only the case with MDAC2.5 and older or something like
that. I believe the more recent versions of Jet are cool with not using the
*.

Really? I'll have to try that ... yes, I guess you're right. But the * still
works fine.
