Figure 19-2. The range as a union

The code:

Dim rng As Range Set rng = Range("B4:C5, E2:E7") MsgBox rng.Columns(1).Cells(1, 1).Value

displays a message box containing the x shown in cell B4 in Figure 19-2 because the indexes in the Cells property are taken relative to the upper cell in the leftmost area in the range.

Note that we can use either integers or characters (in quotes) to denote a column, as in:

Columns(5)

and:

Columns("E")

We can also write, for instance:

Columns("A:D")

to denote columns A through D. Similarly, we can denote multiple rows as in:

Rows("1:3")

Since a syntax such as:

Columns("C:D", "G:H")

does not work, the Union method is often useful in connection with the Columns and Rows methods. For instance, the code:

Dim rng As Range Set rng = Union(Rows(3), Rows(5), Rows(7)) rng.Select

selects the third, fifth, and seventh rows of the worksheet containing this code or of the active worksheet if this code is in a workbook or standard code module.
