SUMMARY
The Microsoft Excel versions mentioned at the beginning of this article do not include a Microsoft Visual Basic for Applications function to determine

if a workbook is already open. The following sample user-defined function loops through all of the opened workbooks in memory to determine if a specific workbook is already open in the current instance of Microsoft Excel.

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. The following sample Visual Basic Sub procedure calls the user-defined IsOpen function. Sub Test If IsOpen("Book1.xls") Then MsgBox "The file is open." Else MsgBox "The file is not open." End If  End Sub 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 In the above example, the IsOpen function returns a True if Book1.xls is already open in the current instance of Microsoft Excel; otherwise, IsOpen returns False.
