I'm using VB6 pro edition.

I try to compact my Access-database every time when I close my program.
Way I tryed to do it:

CompactDatabase App.Path & "/database.mdb", App.Path & "/newdatabase.mdb"
.
.

But when I do this vb gives me an error:
sub of function not defined...

What could be wrong? I remember that I have used this method sometimes before without any problems...

Thanks in advance!

The function is part of DAO.
Reference DAO and VB will know the function.

Now I got an error which says that database is already open. I have DbGrid and Data controller in my form which is connected to that database. So I have close that connection before I can compact that database. How I close connection?

   Dim db As String
    db = Data1.DatabaseName
    Data1.DatabaseName = ""
    Data1.Refresh
    DBEngine.CompactDatabase "olddb", "newdb"
    Data1.DatabaseName = db

where data1 is the name of your data controler.

and refresh after setting back the databasename, of course.
That should save you.
