[2005] Syntax error in INSERT INTO..in ado.net

[crystalsnehal]

hi,
im trying out a simple code in which i add data to my database.....

  Dim dr As DataRow
        strconn = "Provider=Microsoft.Jet.OLEDB.4.0;Data Source=d:\rs232\rem.mdb;User Id=;Password=;"

        Dim cmd As New OleDbCommand("INSERT INTO reminderdata (datetime, reminder)VALUES('" & txtdate.Text & "','" & txtreminder.Text & "')", New OleDbConnection(strconn))

        cmd.Connection.Open()
        cmd.ExecuteNonQuery()
        cmd.Connection.Close()

but its giving me error saying Syntax error in INSERT INTO statement

so i tried the code given here

dr = ds.Tables(0).NewRow()  'Gets a reference to a new row.
        dr("datetime") = txtdate.Text
        dr("reminder") = txtreminder.Text


       ds.Tables(0).Rows.Add(dr)
       da.Update(ds)
       ds.AcceptChanges()

and declared the insert command as

da.InsertCommand = New OleDbCommand("INSERT INTO reminderdata(datetime, reminder) VALUES(@datetime,@reminder)")
        da.InsertCommand.Connection = conn
        da.InsertCommand.Parameters.Add("@datetime", OleDbType.VarChar, 40, "datetime")
        da.InsertCommand.Parameters.Add("@reminder", OleDbType.VarChar, 40, "reminder")

but i got the same error.....

plz help me resolve the error.....
