Test for worksheet in a closed workbook.

I need to test to see if a worksheet exists in a closed workbook. I am currently using the code I found posted on this site that allows you to access data from a closed workbook;

Private Function GetValue(path, file, sheet, ref)
'   Retrieves a value from a closed workbook
    Dim arg As String

'   Make sure the file exists
    If Right(path, 1) <> "\" Then path = path & "\"
    If Dir(path & file) = "" Then
        GetValue = "File Not Found"
        Exit Function
    End If

'   Create the argument
    arg = "'" & path & "[" & file & "]" & sheet & "'!" & _
      Range(ref).Range("A1").Address(, , xlR1C1)

'   Execute an XLM macro
    GetValue = ExecuteExcel4Macro(arg)
End Function


however, I have not been able to modify it to only test for the existance of a specified worksheet in the closed workbook.  Any help would be greatly appreciated?

try this

Function chkSheet(sht As String) As Boolean
Dim xlObj As Object, j As Integer
Set xlObj = CreateObject("excel.application")
    xlObj.workbooks.Open "C:\MyXx.xls", , True
    With xlObj
        For j = 1 To .worksheets.Count
            If .worksheets(j).Name = sht Then
                chkSheet = True
                Exit For
            End If
        Next
    End With
    xlObj.Quit
    Set xlObj = Nothing
End Function

Without open the workbook and getting the sheetnames you might take a look at:

http://j-walk.com/ss/excel/eee/eee015.txt
Search for: ReadSheetNames

To use this example you need to set the following references in the VBA editor:
"Microsoft
ActiveX Data Objects 2.1 Library" and "Microsoft ADO Ext. 2.1 for DDL and
Security".

Here an example of the code:

Sub ReadSheetNames(TheCompleteFilePath As String)
    Dim cnn As New ADODB.Connection
    Dim cat As New ADOX.Catalog
    Dim tbl As ADOX.Table

    cnn.Open "Provider=MSDASQL.1;Data Source=" _
     & "Excel Files;Initial Catalog=" & TheCompleteFilePath
    cat.ActiveConnection = cnn
    For Each tbl In cat.Tables
        MsgBox Left$(tbl.Name, Len(tbl.Name) - 1)
    Next tbl

    Set cat = Nothing
    cnn.Close
    Set cnn = Nothing
End Sub


Sub test()
Call ReadSheetNames("D:\My documents\Test.xls")
End Sub


regards,
Jeroen

I've tried capricorn1 code - returns the following error "function call on left hand side of assignment must return a variant or object" This appears to occure where you set chkSheet = true.

Will look into the other options today.

how did you use the function?
did you copy the function as it is?

Found the problem. I changed the function a little (send the path and sheet name). The problem was a typo on my part. Works great.

Thanks for all of you folks support.
