"Backward compatible" ---> this seems to be my problem. There are properties that I used from Excel2000 that causes broken VI when I use the VI in a machine with ExcelXP or Excel2003. An example is the Value property of Range. Upon inspection, it seems that Range in ExcelXP and Excel2003 does not have the Value property. Only Value2.
With an understanding of Microsoft, I think that there are properties and methods that are added, "deleted" or modified in every change of version. Am I correct?
If so, can anyone give me a link that will point point to the properties and methods that are added, "deleted" or modified since Excel2000?
