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
IsFileOpen()

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,

Steven
