To create the user-defined function IsOpen, follow these steps:  Start Microsoft Excel. Press ALT+F11 to start the Visual Basic editor. On the Insert menu, click Module.  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:  Start Microsoft Excel.</li> Press ALT+F11 to start the Visual Basic editor.</li> On the Insert menu, click Module.</li>  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 </li></ol>
