Hi,
Some time ago I tryed the same thing. I had to refresh a whole bunch of
query's and table's in a whole bunch of Access-databases. I looked some days
on the internet for solutions, tryed really a lot, but nothing worked really
fine. I had some solution that for some reason didn't work with every
table/query, and I never foudn out why. I ended up doing this in Access,
hehe.
Maybe you can do something with my VB.NET code? Maybe you can find usefull
things in it or improve it?
If you findsomething that really works, can you post it please?
Pieter

table, it is working fine. But, I got a problem when I tried to link
