Visual Basic 2010 - Dynamic Tabs, Controls & Recording Data - database

Question

I'm posting this after losing my time by searching & got no proper answer.
My requirement is to create a permit system.
There is a tabcontrol on the form & when I click on "New Permit" button (located top of the form above tabcontrol), a new tab should open (named "NEW Permit") with text boxes on it.
Each time "New Permit" button is clicked, same type of tabs to be opened parallely.
When we select a one tab & fill in the text fields & click on "Issue Permit" button (located top of the form above tabcontrol), tab should be closed while saving the data in text fields to a access database with a dedicated permit number.
I have created the form & the "New Permit","Issue Permit" buttons & tabcontrol are on a usercontrol "ucPermit".
I'm struck in creating those dynamic tabs & getting the data on those into a database.

I have two panels on the form.
Panel 01 (on left) has buttons "Summary, Permit, LOTO, HotWork".
When each button is clicked respective usercontrol (loaded onto panel 02 on right at runtime) comes to front.
Public Class Home
Dim ucSummary As New ucSummary
Dim ucPermitMain As New ucPermitMain
Dim ucLotoMain As New ucLotoMain
Dim ucHotWorkMain As New ucHotWorkMain
Private Sub Home_Load(ByVal sender As Object, ByVal e As System.EventArgs) Handles Me.Load
lblDate.Text = Format(Now, "MMMM dd, yyyy")
lblTime.Text = Format(Now, "h:mm tt")
btnSummary.BackColor = Color.LightGreen
Panel2.Controls.Add(ucSummary)
ucSummary.Dock = DockStyle.Fill
Panel2.Controls.Add(ucPermitMain)
ucPermitMain.Dock = DockStyle.Fill
Panel2.Controls.Add(ucLotoMain)
ucLotoMain.Dock = DockStyle.Fill
Panel2.Controls.Add(ucHotWorkMain)
ucHotWorkMain.Dock = DockStyle.Fill
End Sub
Private Sub btnSummary_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles btnSummary.Click
btnSummary.BackColor = Color.LightGreen
btnPermit.BackColor = Color.LightBlue
btnLoto.BackColor = Color.LightBlue
btnHotWork.BackColor = Color.LightBlue
ucSummary.BringToFront()
End Sub
Private Sub btnPermit_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles btnPermit.Click
btnSummary.BackColor = Color.LightBlue
btnPermit.BackColor = Color.LightGreen
btnLoto.BackColor = Color.LightBlue
btnHotWork.BackColor = Color.LightBlue
ucPermitMain.BringToFront()
End Sub
Private Sub btnLoto_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles btnLoto.Click
btnSummary.BackColor = Color.LightBlue
btnPermit.BackColor = Color.LightBlue
btnLoto.BackColor = Color.LightGreen
btnHotWork.BackColor = Color.LightBlue
ucLotoMain.BringToFront()
End Sub
Private Sub btnHotWork_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles btnHotWork.Click
btnSummary.BackColor = Color.LightBlue
btnPermit.BackColor = Color.LightBlue
btnLoto.BackColor = Color.LightBlue
btnHotWork.BackColor = Color.LightGreen
ucHotWorkMain.BringToFront()
End Sub
End Class
I have just started & currently working on Permit section which works with ucPermitMain usercontrol.
It has a toolstrip (tsPermit) on top & an empty tabcontrol (tcPermit) below.
Toolstrip has buttons "NewPermit, Issue, Close" (for now..more to come with design)
Each time NewPermit is clicked new tabs open parallely with text boxes on it.
When selected a particular tab & "Issue" is clicked, the data on the selected tab's text boxes to be put into database "PTW.accdb", & tab to be closed.
Public Class ucPermitMain
Dim PTW As New OleDb.OleDbConnection
Dim ucPermit As New ucPermit
Dim txtbox As New TextBox
Public Sub New()
' This call is required by the designer.
InitializeComponent()
' Add any initialization after the InitializeComponent() call.
PTW = New OleDb.OleDbConnection
PTW.ConnectionString = "Provider=Microsoft.ACE.Oledb.12.0; Data Source=" & Application.StartupPath & "\PTW.accdb"
End Sub
Public Sub tsbtnNewPermit_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles tsbtnNewPermit.Click
tsbtnClose.Visible = True
tsbtnClose.Enabled = True
Dim CTP As New CustomTabPage("New PTW", New Object)
Me.tcPermit.TabPages.Add(CTP)
tcPermit.SelectTab(tcPermit.TabPages.Count - 1)
End Sub
Public Sub tsbtnClose_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles tsbtnClose.Click
tcPermit.TabPages.RemoveAt(tcPermit.SelectedIndex)
'This bottom code is telling it to remove the selected tab and countdown minus (-) 1 (one)
If tcPermit.TabPages.Count > 0 Then
tcPermit.SelectTab(tcPermit.SelectedIndex)
Else
tsbtnClose.Visible = False
tsbtnClose.Enabled = False
End If
End Sub
Public Sub tsbtnIssue_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles tsbtnIssue.Click
Dim cmd As New OleDb.OleDbCommand
Dim CTB As CustomTextBox
If Not PTW.State = ConnectionState.Open Then
'open connection if it is not yet open
PTW.Open()
End If
cmd.Connection = PTW
cmd.CommandText = "INSERT INTO tblPermit(ptwNo)" & _
"VALUES('" & ?????????????? & "')"
cmd.ExecuteNonQuery()
End Sub
End Class
CustomTextBox & CustomTabPage are two seperate classes to create these custom controls.
Imports System.Windows.Forms
Public Class CustomTabPage
Inherits TabPage
Public Sub New(ByVal Name As String, ByVal NewConstruct As Object)
InitTextBox(1)
Me.Text = Name
End Sub
Private Sub InitTextBox(ByVal Num As Integer)
Dim LocX As Integer = 10
Dim LocY As Integer = 10
Dim CTB As New CustomTextBox("")
CTB.Location = New System.Drawing.Point(LocX, LocY)
Me.Controls.Add(CTB)
End Sub
End Class
Imports System.Windows.Forms
Public Class CustomTextBox
Inherits TextBox
Public Sub New(ByVal Name As String)
Me.Text = Name
End Sub
End Class
This is only code I have done upto now & they may be not optimized.
Hope you will spend your time to go through.

The lesson here is to have a Data Layer, this layer has all the methods and logic for saving data to the database. When the new tab is built you have a property that allows it to access the Data Layer. It might even need some encapsulation(UserControl) with having a group of control that the same logic for saving/validating data.
You also should show some code - an effort on your part before asking for help.
