To successfully trap the value returned by clicking Cancel, you need to add error handling to your code. The following is an example of error handling that you can use with the InputBox method, to prevent the error message described in this article.

1. Start Excel and create a new workbook.
2. Press ALT+F11 to open the Visual Basic Editor.
3. On the Insert menu, click Module and type the following code in the new module:
   

      Sub CountColumns()
      ' Dimension myRange variable.
      Dim myRange As Object
      ' Begin error trapping.
      On Error GoTo ErrHandler
      ' Store InputBox value into variable myRange.
      Set myRange = Application.InputBox(Title:="Count Columns", _
      Prompt:="Select range to count number of columns.", Type:=8)
      ' Show message box.
      MsgBox myRange.Columns.Count
      ' End macro.
      End
      ' Show message box when Cancel is clicked or other error
      ' is encountered.
      ErrHandler: MsgBox "No columns selected."
      End Sub
