How to delete datawindow row by loop?

Question

I try to go through datawndow rows by for loop and delete those rows I found with condition.  Something like:
For i = 1 to dw_1.RowCount()
  if expression then 
    dw_1.DeleteRow(i)
  end if
Next
Looks like not working properly. if DeleteRow dynamically change RowCount()? how to resolve this problem?

Answer 1

If you must go from row 1 to RowCount(), then try this:
long ll_Row
ll_Row = 1
DO WHILE ll_Row <= dw_1.RowCount()
     IF expression THEN
          dw_1.DeleteRow(ll_Row)
     ELSE
          ll_Row++
     END IF
LOOP
