Which is faster... or better programming
I was wondering which method people would recommend to do teh following.
There are two workbooks Old.xls and New.xls. I need to compare the value/string in each cell in Column A in Old.xls with the cells in Column A in New.xls. When matched then the value in Column I in Old.xls must be added to the value in the corresponding row in Column I in New.xls So...is it better to do row by row comparison and a single addition between workbooks? Or should I create an array from the Old.xls with just Column A and Column I and then do the comparison and addition? Or should I create ranges of Column A in the New.xls and do the comparison with an Intersect function? Or...? There are always better ways to do things and I would like to see what others have experienced. thanks |
