listbox - Multiple Buttons keypad in VB.net -

I have battled with this for three days and asked a lot of people questions, but maybe I ask it wrong I am What I'm doing is to create a digital secure lock, I need to get the following:

I have created a keypad with six buttons in a group box. When one click on the button, the number should be clicked on the list that should be displayed in the list. You must press the button on the comfort (up to six digits maximum) all the way a one calculator is sorted in order to display in the listbox next to each other, and then the listbox should display them in the same way. In . Whit here I have traced up to date:

  public class form1 private sub btn1_Click (as the object, e) Event brox1.Click the handle as btn1.Click then pinlst.Items.Count = 0 Then pinlst .ems.Add (btn1.Text) or else pinlst.Items (0) .SubItems.Add (btn1.Text) Finish End Sub Personal sub btn2_Click (this object, as in EventArgs form) btn2.Click The management does have pinlst.Items. Calculate = 1 Then the pinlet. Items.ed (BTN2 text) Other pinlist. Items (1) .SubItems.Add (BTN 2 Test) And If End Sub Private All BTN3_Click (Object as Sender, and Event as ARG) BTN 3. Click if pinlst.Items.Count = 2 then PinLaste. I.e.s.Ed (BTN 3.Text) Other PinList.Eight (2) .SubItems.Add (btn3.Text) End if end sub-private sub btn4_Click (as the sender object, and eventArgs) handles BT4. Click pinlst.Text = BTN 4.Text & Sub Personal Sub BTN 5 Link (Sender A, Object, as E EventArgs) Handle btn5.Click pinlst.Text = btn5.Text End Sub Personal Sub btn6_Click (The form of this object In the form of E EventArgs) handle btn6.Click pinlst.Text = btn6.Text End Handles subtotal sub btngp_Enter (as the object, e eventArgS) handles BTNGP.inter pinlight. Text = pinlight Text & amp; BTN 1.Text PinLast Text = pinlight Text & amp; Btn2.Text PinList Text = pinlight Text & amp; Btn3.Text PinList Text = pinlight Text & amp; Btn4.Text PinList. Text = pinlight Text & amp; Btn5.Text PinList Text = pinlight Text & amp; Btn6.Text End Sub End Class  

This is being done for a character The button is best designed to be in time, pressed or being a function. To work for this, you have to keep each button in the form of a custom control, of course, highlighting the "CharPressed" property, or something like that, based on a regular button, you can make a stable handler for all the buttons. That is, you will dynamically strings after the sub new in the initializeComponent . If this does not make sense, please do not hesitate to ask a question in the comments.
