Inserting data into a database from vb6?

i am working on a program that takes some data from a listview object and should among other things insert the data into specific fields in a database. i am using vb6 and a ms access 2003 database. im not entirely sure how to connect to the database in vb6 although i do have this code at the moment

Option Explicit
Public dbCaseGoods As DAO.Database
Dim rs As DAO.Recordset
Dim Barcode() As String
Dim linenumber As Integer
Dim strinsert As String



Private Sub btnDone_Click()
linenumber = 1
strinsert = "INSERT INTO Work_Order (PO_Number,CNC_Code,Line_No) VALUES ('" & "PO NUMBER" & "', '" & "CNC CODE" & "', '" & "LINE NUMBER" & "')""
'strinsert = "INSERT INTO Work_Order (PO_Number,CNC_Code,Line_No) VALUES ('" & ListView1.ListItems(linenumber).Text & "' , '" &     ListView1.ListItems(linenumber).SubItems(1) & "','" &     ListView1.ListItems(linenumber).SubItems(2) & "')""
Set rs = dbCaseGoods.execute(strinsert, dbfailonerror)

txtbarcode.SetFocus
End Sub

Private Sub Command1_Click()
Form2.Show
End Sub

Private Sub Form_Load()
Set dbCaseGoods = OpenDatabase("I:\Casegoods\database\Contract_Casegoods.mdb")

ListView1.ColumnHeaders.Add Text:="P.O#", Width:=ListView1.Width / 3
ListView1.ColumnHeaders.Add Text:="Cnc Code", Width:=ListView1.Width / 3
ListView1.ColumnHeaders.Add Text:="Line #", Width:=ListView1.Width / 8
End Sub



Private Sub txtbarcode_KeyPress(KeyAscii As Integer)
Dim li As ListItem


Barcode = Split(txtbarcode.Text, "-")
On Error Resume Next
   If KeyAscii = vbKeyReturn Then
   Set li = ListView1.ListItems.Add(, , Barcode(0))
   li.SubItems(1) = Barcode(1)
   li.SubItems(2) = Barcode(2)
   txtbarcode.Text = ""
   Command2.Caption = ListView1.ListItems(1).Text
   Command3.Caption = ListView1.ListItems(1).SubItems(1)
   Command4.Caption = ListView1.ListItems(1).SubItems(2)
End If

End Sub

what i am getting right now when i try to hit the button to insert the one line of data into the database is an error stating Expected function or variable and .Execute is highlighted in Set rs = dbCaseGoods.execute(strinsert, dbfailonerror)
