Subject Re: [IBO] Black IB_Edits?

Hi Helen

I tried the suggestion regarding conflicting uses still seem to have
the problem though :(

Moving everything to a datamodule solves it though thank you.

Out of interest, I was only using one datamdule per project, and
finding it very difficult to keep track on exaclty what each query was
for. Is it better to use several datamodules? One for each type task



PS I think you book is excellent! It lives on my desk :) I have, and
do buy a lot of books, but your Firebird Book is one that I have found
to be one of the most usefull, as it has a very good index, is easy to
read and normally seems to have the answer I'm looking for!
