on error resume next
    m_RS.Delete
    if err.number<> 0 then
        err.raise vbObjectError + 512 + 20, err.source, err.description
        exit sub
    end if

The caller's code is:

    on error resume next
    DBATables.Delete
    if Err.Number = 0 then
        do something

The err.raise in the server is executed because of referential constraints in the
database, however the Err.Number in the caller process is always 0 and the
"do something" lines always execute.  The failure is not limited to this method
and call, all err.raise from the server fail in the caller.

This was working previously, something I have done must have broken it, but I
don't have a clue what it was.  I would greatly appreciate any help you could
give me.
