Hi Mike

The best place to get help with a basic automation question is the excel.programming newsgroup. The folks there are VBA-centric, but they really know Excel inside-out. This forum is really dedicated to the VSTO technology, although object model questions do get answered, on occasion. But your request is so specialized, you should go right to the experts :-)

If you're programming in C# and get some VBA code you can't get to work, feel free to ask in the office.developer.automation newsgroup for assistance.
