I may be creating a small Excel-based VBA application for a client on a semi-formal basis. I personally use Windows XP with Office XP installed, but I'm concerned about the possibility of serious differences between versions of Windows and Excel that may cause my code to fail on other machines.
I don't think I need to cater to any version of Excel BEFORE that in Office XP, but I probably do need to cater for versions after it. That's Office 2003, Office 2007 and Office for Vista, I think.
Does anyone either know of a good concise reference that details any possible pitfalls, or can anyone give any examples here of common things to avoid.
Or, am I worrying too much, and is everything supposed to be pretty much compatible!? (That would be far too easy, I'm sure!)
Thanks in advance!
