Hi, I have a very large large spreadsheet with 20000 rows and about 50 columns most with long complex formulas so calculation on this sheet takes time. The main purpose of my code is to perform a Goal Seek but depending on results the code might loop up to 100 times. Each Goal Seek takes about 9 minutes!
One column from the table changes at each iteration so what I want to do is copy this column to another workbook, perform the Goal Seek, then copy back my required result. My problem is though that if the second workbook is in the same Excel instance as the actual table the process is just as slow. So, my question is how do I access a completely separate instance within my VBA code so as to paste the 20000 line column, perform the goal seek in that workbook then copy the result back Any help appreciated ..pc --~--~---------~--~----~------------~-------~--~----~ ---------------------------------------------------------------------------------- Some important links for excel users: 1.
