VSTO is a "Office 2003" integration library that claims to replace the VBA
in Office with .NET. In reality, you don't need it unless you are creating
dialogs for Office. I connect to the Office COM objects and use the native
object models. VS 2005 will create the interop libraries for you.

What is Visual Studio Tools for Office (VSTO) (I have Office Professional
Version 10.0 and Visual Studio.NET as well as VB6.0) so is VSTO a
separate
piece of software that one has to buy in addition to buying Office 2003
and
Visual Studio 2003?

Google web search is your friend.

Even searching Microsoft's own site would be useful.

That said, it's more likely the average Visual Studio developer would
know more about VSTO than the average Excel user, so you may get a
better answer in

to which I've crossposted this reply.
