Hi All!

I have been creating "Tools" for about a year now using VBA in Excel 2002. My company has finally gotten me Visual Studio and I would like to migrate my code over. After reviewing different choices, it looks like moving the tools into a DLL and using an add-in to call them will be our best option.

I would like to write the DLL in C#, but I've heard that launching .NET code from inside Excel is really slow. I would also be open to writing the DLL in C++ or VB, but would prefer C#.

Does anyone have any advice or thoughts that could be useful as I start this process?

Thanks!
Matt
