Hello, im working on a project that works with an access database but i dont know how to edit an existing record...

here is the code that i use for reading the database:

Public Function ask()

        Dim dt As New DataTable
        Dim ds As New DataSet
        ds.Tables.Add(dt)
        con.Open()
        Dim da As New OleDbDataAdapter("select * from data", con)
        da.Fill(dt)
        Dim newRow As DataRow = dt.NewRow
        For Each DataRow In dt.Rows

            If CardID.Text = DataRow.Item(0) Then
                usrname = DataRow.Item(1)
                cardv = DataRow.Item(0)
                usrid = DataRow.Item(2)

                log2.DataSource = dt.DefaultView
                DataRow.Item("card") = cardv
                'dt.Rows.Add(newRow)
                Dim cb As New OleDbCommandBuilder(da)
                log.DataSource = dt.DefaultView
                da.Update(dt)

                Return True
            Else

            End If
        Next

        con.Close()





        Return False


        
    End Function

Here is the code i used to add a new record:

con.Open()
        Dim dt As New DataTable
        Dim ds As New DataSet
        ds.Tables.Add(dt)
        Dim da As New OleDbDataAdapter("select * from data", con)
        da.Fill(dt)

        Dim newRow As DataRow = dt.NewRow
        With newRow
            .Item("card") = cardtxt.Text
            .Item("name") = nametxt.Text
            .Item("id") = idtxt.Text
            .Item("in") = ComboBox1.Text
        End With
        dt.Rows.Add(newRow)
        Dim cb As New OleDbCommandBuilder(da)
        da.Update(dt)
        DataGridView1.DataSource = dt.DefaultView
        con.Close()
        cardtxt.Clear()
        nametxt.Clear()
        idtxt.Clear()
        cardtxt.Select()

now, both of those codes work just fine(I know you will say there is an easier way to use access, but trust me, i need it this way).

So how could i edit an existing record?

It looks like you already know about

Dim cb As New OleDbCommandBuilder(da)
        da.Update(dt)

What seems to be the problem?

there is no problem, i just want to know how to edit a certain record:

for example i want it to find the record where DataRow.Item(0) is "123" then it it change the record's DataRow.Item(0) to "321"
