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.

Private Sub mnuCompactMDB_Click()

   Dim strSource As String

   Dim strDestination As String

   

   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" _

        & "Provider=Microsoft.Jet.OLEDB.4.0;" _

        & "Data Source= & strDestination" _

        & ";Jet OLEDB:Engine Type=5"

        

        Kill strSource

        Name strDestination As strSource

        Set jro = Nothing

     

   End If

End Sub

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
     End Sub
     
     Sub test()
         CompactAccessDataBase "C:\YourDatabase.mdb", "C:\YourDatabase_NEW.mdb"

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.
