{

    object[] oParams;

    //create an inctance of a Jet Replication Object

    object objJRO =

      Activator.CreateInstance(Type.GetTypeFromProgID("JRO.JetEngine"));

    //filling Parameters array

    //cnahge "Jet OLEDB:Engine Type=5" to an appropriate value

    // or leave it as is if you db is JET4X format (access 2000,2002)

    //(yes, jetengine5 is for JET4X, no misprint here)

        connectionString,

        "Provider=Microsoft.Jet.OLEDB.4.0;Data" +

        " Source=C:\\tempdb.mdb;Jet OLEDB:Engine Type=5"};

    //invoke a CompactDatabase method of a JRO object

    //pass Parameters array

        System.Reflection.BindingFlags.InvokeMethod,

        null,

        objJRO,

        oParams);

    //database is compacted now

    //to a new file C:\\tempdb.mdw

    //let's copy it over an old one and delete it

    System.IO.File.Delete(mdwfilename);

    System.IO.File.Move("C:\\tempdb.mdb", mdwfilename);

    //clean up (just in case)
