VB.net, OLEDataConnectors and Access... DB Not updating?!

[teammcs]

Hey all,

I'm new around here but do Admin over @ PHPHelp.com... I've been developing a project for my degree which is basically based around an ATM machine.

Basically my problem is related to the updating of the database, I can't seem to see why it doesn't do anything despite no errors showing up...

Just a bit of background first..

DT is a data tables globally declared within my class...

Basically this problem applies to add a new row and updating a existing one. Although the data table HAS updating (I can check via echoing the related field) the ole connection doesn't appear to actually send it to the db

My new field query is:

        Query("SELECT [accountNumber],[cardNumber],[transationAmount] FROM transactions") ',[transactionDate] // Populates the data table.. works fine
        MsgBox(dt.Columns.Count)
        Try
            newRecord = dt.NewRow
 
            newRecord("accountNumber") = CStr(Me.accountNum) '
            newRecord("cardNumber") = CStr(Me.cardNum) '
            newRecord("transationAmount") = CStr(amount) '
            dt.Rows.Add(newRecord)
            updateData() 
        Catch ex As Exception
            Form1.msgReturn(ex.Message, Form1.rtnInital)
        End Try

the actual update function is:

    Private Function updateData()
        dt.AcceptChanges()
        'MsgBox(dt.Rows(0)("accountBalence"))
        Try
            Dim cmdbuilder As New OleDb.OleDbCommandBuilder(Form1.OleDbDataAdapter1)
            Form1.OleDbDataAdapter1.Update(dt)
            Return True
        Catch ex As Exception
            dt.Clear() 'Removes previous data set
            MsgBox(ex.Message)
            Return False
        End Try
 
    End Function

Does anyone have any ideas... my head hurts :P
