You'd need to get your hands on Visual Studio Tools for Office
(VSTO) to make he bridge between Office and NET.

Hallo,

I work on a computer with EXCEL 2003 and Windows XP Pro. I
have the following question:

Is it possible to use system.diagnostics in EXCEL-VBA? If yes:
what do I have to do? If my knowledge is correct then
system.diagnostics is part of the NET Framework Class Library.

Thank you very much for any response!
