Binding text boxes and combo boxes to access using VB

Hello everyone,  I've been putting of this project for years but now I see an oppertunity to learn a new skill and code in VB.  At uni I learnt code in VBA in Access but I want to be able to link my relational database to a VB front end.  Going through countless Youtube videos I'm still non the wiser.  I managed to create my first login form and link that to the database that I'm so proud of.  As part of that I created a module that connects VB to the database see below Module Module1 and this works.

So having this connection how do I link say textbox1; Textbox2 and a combo box to my database.  Please be as basic as possible as I'm just learning.  I have put on the Student add form

Imports System.Data.OleDb
Imports System.IO

------------------------------------------------------------------------------------------------------------

       'Module1

        Public cn As New OleDb.OleDbConnection
        Public cmd As New OleDbCommand
        Public da As New OleDbDataAdapter
        Public ds As New DataSet
        Public ds1 As New DataSet
        Public ds2 As New DataSet
        Public str As String

        Public Sub conn()

        cn.ConnectionString = "Provider=Microsoft.ACE.OLEDB.12.0;" + "Data Source=C:\Users\NewViper\Desktop\MHS ICT Data BaseV3Beta.accdb"

    End Sub

    End Module

--------------------------------------------------------------------------------------------------

'Here is the Student Add Form that I created but getting lost and confused

ds.Clear()
        'datetimepicker1.value = DateTime.Now

        If cn.State = ConnectionState.Open Then
            cn.Close()
        End If

        Module1.conn()
        cn.Open()



        cmd.Connection = cn
        cmd.CommandText = "insert into TblUser(UserNameID, UserschooID,Forname,Surname,GenderID,HouseID,YearGroup)" &
                        = values(" & me.txtUsername.text & ", " ")
