I am currently converting an application from Vb.Net Interop to the XLSIO language and this is an area that, in interop, is 1 line of code and occurs nearly instantly. The code below took well over 4 minutes and by then it was apparent it would not work. I converted this into VB.net (from C#). Is my code wrong? There are 60 thousand lines it has to go through, so quite a long time.
