undo changes

  Asked By: Dylan    Date: Oct 05    Category: MS Office    Views: 548
  

Is it possible to undo changes done in a spreadsheet thru a macro
itself. Eg. If a for loop is updating some values in columb D based on
values in columns A,B & C. But if value in any cell is negative, loop
is to be terminated as well as changes done in column D also to be
undone.

Why not run a check BEFORE you start your loop?
Check to see if there are any negatives in your range. If so, you stop the
loop from making any changes thus you won't have to undo  anything. As an added
bonus, it will save running time on your macro.

Sub NegCheck()
ColumnMin = Application.WorksheetFunction.Min(Range("A1:C65536"))
If ColumnMin < 0 Then Exit Sub
End Sub
