1. Start Microsoft Excel.
2. Press ALT+F11 to start the Visual Basic editor.
3. On the Insert menu, click Module.
4. In the module sheet, type the following code:

   Function IsOpen(FileName As String) As Boolean
       Dim wb As Workbook
       For Each wb In Application.Workbooks
           If UCase(wb.Name) = UCase(FileName) Then
               IsOpen = True
               Exit Function
           End If
       Next wb
       IsOpen = False
   End Function
   						

The following sample Visual Basic sub procedure calls the user-defined IsOpen function. The IsOpen function returns a True if Book1.xls is already open in the current instance of Microsoft Excel; otherwise, IsOpen returns False.

You can use the following code to test for any Excel Workbook by replacing the workbook name "Book1.xls" with the workbook you want.

To create a sub procedure to test for an open Excel workbook, follow these steps:

1. Start Microsoft Excel.
2. Press ALT+F11 to start the Visual Basic editor.
3. On the Insert menu, click Module.
4. In the module sheet, type the following code:

   Sub Test()
       If IsOpen("Book1.xls") Then
          MsgBox "The file is open."
       Else
          MsgBox "The file is not open."
       End If
   End Sub
