It then omits the fact that you need to #include for the sprintf() function. Now, in order to accomplish what you want you need to know what properties and methods the Excel objects expose. This sounds very bad, but it isn't because the vast majority of the execution time taken with a typical Excel add-in or application involves calls to the Excel object model, so If you're new to Tech Support Guy, we highly recommend that you visit our Guide for New Members.

VSTO is a gorgeous system for making very rich Excel add-ins, but execution speed is its weakness for applications such as yours. This is way too slow, and you can watch this progress by eye. What I can't understand is how GetActiveObject can return "Success" is I do not have Excel currently running?

It's not free, but it would allow you to code in C# and although it shims your solution into a separate AppDomain, I believe that it's execution speed is outstanding.
