Trying to compact access 2000 mdb in vb6 using ADO

I am attempting to add code to existing VB6 program to Compact (and Repair) an Access 2000 MDB using tthe Microsoft jet and Replication Objects library 2.6

I am getting an error message at the statement below jro.CompactDatabase "Provider=Microsoft.Jet.OLEDB.4.0;" stating that the argument iCompactDatabase s not optional.  It is probably in the syntax that I just cook booked code from an internet site and only changed the data base names.  I just can't see where the problem is and was hoping that someone more familiar with this task could help.

   Dim Response As Integer
   Response = MsgBox("Compact ARSSL.mdb ?", vbYesNo)
   If Response = vbNo Then Exit Sub
   MsgBox "NOTE - all other users must be completely out of the program for this operation"
   If Len(Dir$(App.Path & "\data\arssl.ldb")) > 0 Then
       MsgBox ("Database is in use")
       Exit Sub
     Else
       strSource = App.Path & "\data\arssl_data.mdb"
       strDestination = App.Path & "\data\arssl_data_new.mdb"
       Dim jro As jro.JetEngine
       Set jro = New jro.JetEngine
       jro.CompactDatabase "Provider=Microsoft.Jet.OLEDB.4.0;" _
        & "Data Source= & strSource" _

try this one..


     Public Sub CompactAccessDataBase(dbPath As String, NewPath As String)
         Dim acc As Object
         Set acc = CreateObject("Access.Application")
         acc.CompactRepair dbPath, NewPath
         Set acc = Nothing

this one also...

Add as reference to DAO 3.51 or later to your project and
use DBEngine.Compact database here's an example.


Sub CompactDatabaseX()

   Dim dbsNorthwind As Database

   Set dbsNorthwind = OpenDatabase("Northwind.mdb")

   ' Show the properties of the original database.
   With dbsNorthwind
      Debug.Print .Name & ", version " & .Version
      Debug.Print "  CollatingOrder = " & .CollatingOrder
      .Close
   End With

   ' Make sure there isn't already a file with the
   ' name of the compacted database.
   If Dir("NwindKorean.mdb") <> "" Then _
      Kill "NwindKorean.mdb"

   ' This statement creates a compact version of the
   ' Northwind database that uses a Korean language
   ' collating order.
   DBEngine.CompactDatabase "Northwind.mdb", _
      "NwindKorean.mdb", dbLangKorean

   Set dbsNorthwind = OpenDatabase("NwindKorean.mdb")

   ' Show the properties of the compacted database.
   With dbsNorthwind
      Debug.Print .Name & ", version " & .Version
      Debug.Print "  CollatingOrder = " & .CollatingOrder
      .Close
   End With

End Sub


i hope this will give idea...

I wanted to stay with ADO

Finally made it work.  I will post the code snipet for anyone else needing to perform a similar task.

Thanks for your help.  Really appreciate it.
