XL97: Deleting Cells with a For Each...Next Loop

• Microsoft Excel 97 for Windows

SUMMARY

The way that Microsoft Excel 97 deletes cells in a For Each...Next loop in differs from the way that earlier versions of Microsoft Excel delete cells. This article describes the differences and provides a Visual Basic for Applications macro example that illustrates how to delete cells in a loop.

Typing Sample Data

To use the macro in this article, type the following sample data in a worksheet:

   A1:  a  B1:  1
   A2:  b  B2:  2
   A3:  x  B3:  3
   A4:  x  B4:  4
   A5:  c  B5:  5
   A6:  x  B6:  6
   A7:  d  B7:  7
   A8:  x  B8:  8
   A9:  x  B9:  9
   A10: e  B10: 10

Typing the Sample Macro

In a new macro module, type the following macro:

   Sub DeleteCells()

       'Loop through cells A1:A10 and delete cells that contain an "x."
       For Each c in Range("A1:A10")
           If c = "x" Then c.EntireRow.Delete
       Next

   End Sub

Behavior of the Sample Macro in Microsoft Excel 97

When you run the macro DeleteCells in Microsoft Excel 97, only rows 3, 6 and 8 are deleted. Although rows 4 and 9 contain an "x" in column A, the macro does not delete the rows. The results of the macro in Microsoft Excel 97 are as follows:

   A1: a   B1: 1
   A2: b   B2: 2
   A3: x   B3: 4
   A4: c   B4: 5
   A5: d   B5: 7
   A6: x   B6: 9
   A7: e   B7: 10

Behavior of the Sample Macro in Microsoft Excel 5.0 and 7.0

When you run the macro DeleteCells in Microsoft Excel 5.0 and 7.0, the macro deletes all rows that contain an "x." The results of the macro in Microsoft Excel 5.0 or 7.0 are as follows:

   A1: a   B1: 1
   A2: b   B2: 2
   A3: c   B3: 5
   A4: d   B4: 7
   A5: e   B5: 10

Recommended Method for Using a Loop to Delete Cells

Use the following macro when you want to use a loop to delete cells:

   Sub DeleteCells2()

       Dim rng As Range
       Dim i As Integer, counter As Integer

       'Set the range to evaluate to rng.
       Set rng = Range("A1:A10")

       'initialize i to 1
       i = 1

       'Loop for a count of 1 to the number of rows
       'in the range that you want to evaluate.
       For counter = 1 To rng.Rows.Count

           'If cell i in the range contains an "x",
           'delete the row.
           'Else increment i
           If rng.Cells(i) = "x" Then
               rng.Cells(i).EntireRow.Delete
           Else
               i = i + 1
           End If

       Next

   End Sub

   A1: a   B1: 1
   A2: b   B2: 2
   A3: c   B3: 5
   A4: d   B4: 7
   A5: e   B5: 10

Additional Method for Using a Loop to Delete Cells

This is an alternate method to the method shown above. It will produce the same results.

   Sub DeleteCells3()

       Dim rng As Range, i As Integer

       'Set the range to evaluate to rng.
       Set rng = Range("A1:A10")

       'Loop backwards through the rows
       'in the range that you want to evaluate.
       For i = rng.Rows.Count To 1 Step -1

           'If cell i in the range contains an "x", delete the entire row.
           If rng.Cells(i).Value = "x" Then rng.Cells(i).EntireRow.Delete
       Next

   End Sub
