The button works but after it is pressed the text needs to start when it was left off and not in the beginning.
'' Button to remove 1 number
Private Sub btnCE_Click(sender As Object, e As EventArgs) Handles btnCE.Click
If pinbox.Text.Count > 0 Then '' Works if count is bigger then 0
pinbox.Text = pinbox.Text.Remove(pinbox.Text.Count - 1) '' Remove 1 number
End If
Here is a visual representation of the problem
And yes i am aware that CE is the wrong term used and i will change it :(
I think changing this line in each number:
pinbox.Text= btn7.Text
To:
pinbox.Text= pinbox.Text + btn7.Text
Should put the new text at the end of the pinbox
