MORE INFORMATION

Microsoft provides programming examples for illustration only, without warranty either expressed or implied. This includes, but is not limited to, the implied warranties of merchantability or fitness for a particular purpose. This article assumes that you are familiar with the programming language that is being demonstrated and with the tools that are used to create and to debug procedures. Microsoft support engineers can help explain the functionality of a particular procedure, but they will not modify these examples to provide added functionality or construct procedures to meet your specific requirements.

Sample Visual Basic Procedure

    Sub ConcatColumns()

      Do While ActiveCell <> ""  'Loops until the active cell is blank.

         'The "&" must have a space on both sides or it will be
         'treated as a variable type of long integer.

         ActiveCell.Offset(0, 1).FormulaR1C1 = _
            ActiveCell.Offset(0, -1) & " " & ActiveCell.Offset(0, 0)

         ActiveCell.Offset(1, 0).Select
      Loop

   End Sub

NOTE: The statement ActiveCell.Offset(0, 1).FormulaR1C1 can be replaced with the statement ActiveCell.Offset(0, 1).Formula. They can be used with equal success if you are using text and numbers only (not formulas). The R1C1 used at the end of the first statement refers to row one, column one and is the form used in examples in Help.
