You cannot compact an open MDB from within VB.
The folowing samples are from MSDN:

VB Code:

CompactDatabase Method Example
 
This example uses the CompactDatabase method to change the collating order of a database. You cannot use this code in a module belonging to Northwind.mdb.
 
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
 
This example uses the CompactDatabase method to change the version of a database. To run this code, you must have a Microsoft Jet version 1.1 database called Nwind11.mdb and you cannot use this code in a module belonging to Nwind11.mdb.
 
Sub CompactDatabaseX2()
 
   Dim dbsNorthwind As Database
   Dim prpLoop As Property
 
   Set dbsNorthwind = OpenDatabase("Nwind11.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("Nwind20.mdb") <> "" Then _
      Kill "Nwind20.mdb"
 
   ' This statement creates a compact and encrypted 
   ' Microsoft Jet 2.0 version of a Microsoft Jet version
   ' 1.1 database.
   DBEngine.CompactDatabase "Nwind11.mdb", _
      "Nwind20.mdb", , dbEncrypt + dbVersion20
 
   Set dbsNorthwind = OpenDatabase("Nwind20.mdb")
 
   ' Show the properties of the compacted database.
   With dbsNorthwind
      Debug.Print .Name & ", version " & .Version
      For Each prpLoop In .Properties
         On Error Resume Next
         If prpLoop <> "" Then Debug.Print "  " & _
            prpLoop.Name & " = " & prpLoop
         On Error GoTo 0
      Next prpLoop
      .Close
   End With
 
End Sub
