File or Window is open



Is there a way to tell if a file or window name is open in the current
session of excel and not use the full path. I have seen a routine written of

If IsFileOpen("C:\History\Ac01\File001.xls") Then
'Do this
End If

Function IsFileOpen(filename As String)
Dim filenum As Integer, errnum As Integer

On Error Resume Next ' Turn error checking off.
filenum = FreeFile() ' Get a free file number.
' Attempt to open the file and lock it.
Open filename For Input Lock Read As #filenum
Close filenum ' Close the file.
errnum = Err ' Save the error number that occurred.
On Error GoTo 0 ' Turn error checking back on.

' Check to see which error occurred.
Select Case errnum

' No error occurred.
' File is NOT already open by another user.
Case 0
IsFileOpen = False

' Error number for "Permission Denied."
' File is already opened by another user.
Case 70
IsFileOpen = True

' Another error occurred.
Case Else
Error errnum
End Select
End Function

I would like to just see if the window is open and not have to use the full
path name. Is that possible.

Thank you,

Say we want to know if special.xls is open:

Sub cutaneous()
s = "special"
textt = "special.xls is not open"
For Each wb In Workbooks
If wb.Name = "special" Then
textt = "special.xls is open"
End If
MsgBox (textt)
End Sub

Hello Steven,

You can check if a particular workbook is open the in the current
instance of Excel by iterating through the *Workbooks* object


Function IsWorkbookOpen(ByVal Workbook_Name As String) As Boolean

Dim Wkb As Workbook

For Each Wkb In Workbooks
If Wkb.Name = Workbook_Name Then
IsWorkbookOpen = True
Eixt Function
End If
Next Wkb

End Function
