Keith - thanks. It *is* quite a large development - some of us have
been on it 100% for eight years, and we want to be able to supply it
to students around the world, some of them still using Excel 2000, and
some up to 2003. On the other hand, if there are very large advantages
attached to C# maybe we should migrate in that direction sooner or
later anyway, which you seemed to indicate would only apply if they
had Excel 2003.

Excel 2003 still uses VBA as will the next release of Office
as I understand it. So at this stage there are no compelling
reasons unless you have other code writtent in .net that
you wish to interface with.

I have two developments in hand at present, one is an
Excel Datasheet that interacts with various databases
and is currently written in VBA. That will be migrated
to a COM add-in targetting Excel 2000 and higher to minimise
re-work.

The other interfaces an Excel sheet to proprietary hydraulics
calculation code written in C#, we will use .net for that

Given the complexity of the subject, can we contact
you by e-mail ? Thanks - Charles Jordan

I'd rather you didnt , my employers may take a dim view
of my giving more than general advice.

Keith


Thanks Keith. We'll pursue other avenues - no doubt there are lots. Charles
