Dim db_con As New OleDbConnection("Provider=Microsoft.Jet.OLEDB.4.0;Data Source=" & "DATABASE LOCATION GOES HERE)

        db_con.Open()

        Dim ds As New DataSet

        Dim query1 As String
        query1 = " SELECT * FROM TABLEGOESHERE"
        Dim da As OleDbDataAdapter
        da = New OleDbDataAdapter(query1, db_con)
        da.Fill(ds, "VirusMD5")
        Dim tblstr As String = Nothing
        Dim cmd As OleDbCommand
        Dim dr As OleDbDataReader
        Dim _Ecount As Integer
        _Ecount = ds.Tables("THE TABLE YOU NEED TO READ FROM").Rows.Count
        signatures = _Ecount
        cmd = New OleDbCommand("SELECT * FROM VirusMD5", db_con)
        dr = cmd.ExecuteReader
        While dr.Read
             'You need to figure out how many items their are and what you are reading. See link below

I do not do anything we listviews because I am not familiar with it but getting the data from the database is the same.
To make it do what you want to do edit this part of the code.

Combobox1.Items.Add(dr(0))

Replace that line with adding data to your listveiw. Hope this helps
