Iam trying to see if a worksheet is open.
I have the following code, but it ONLY returns the correct response if it is
called from the same instance of excel as the file is opened.

How can I test for an open file in ANY and ALL instances of excel?

Thanks
Phil

Sub B()
Dim mFilename As String
Dim IsFile As Boolean
Dim FixedName As String
Dim IsOpen As Boolean

mFilename = "c:\current.xls"
IsFile = FileExists("c:\current.xls")
If IsFile Then 'see if file is open
'get filename only
FixedName = FileNameOnly(mFilename)
MsgBox FixedName
IsOpen = WorkbookIsOpen(FixedName)
MsgBox IsOpen


Else
MsgBox "File: " & mFilename & " is not present..."
End If





End Sub





'Some Useful VBA Functions
'VBA has many useful built-in functions, but it lacks the ability to perform
many common tasks. For 'example, if your application needs to determine if a
particular file exists, you need to write 'your own code to make that
determination.

'This tip contains VBA code for six simple, but very useful functions. You
can simply copy the code 'and paste it to your module.

'FileExists - Returns TRUE if a particular file exists.
'FileNameOnly- Extracts the filename part of a path/filename string.
'PathExists - Returns TRUE if a particular path exists.
'RangeNameExists - Returns TRUE if a particular range name exists.
'SheetExists - Returns TRUE if a particular sheet exists.
'WorkBookIsOpen - Returns TRUE if a particular workbook is open.
