I was looking forward to this one. Charles has huge respect in the Excel commuitely, and has a list of achievement’s as long as I am tall. Charles is talking about how hes getting on with writing addins in C. This is proper C  not that C# rubbish!

Charles first makes the case for why he’s moved over to C, 64 bit and speed beign high on the list.  Next its in to VS2010 and Planatech XLL+ with a walk through of how to do it, and some of the gottas for a VBA to C convert. I’ve done a few Pure C XLL’s, using such tools a WXL it works well, but  XLL Plus sure looks nice, I like thoses wizards!!!

Synonymous with Speed Charles Williams at the helm

It was an insightful talk, not only for the how, but also for the, – it takes me longer, but is that because I have worked with VBA for 20 years? – I’ll ask if the speed gap has come down next year Charles!
