Question

I have created the text box, and the generate button.
when I click on the generate button, I want it to display a text box with numbers. How do I do so using the event handler?. Sorry, basic question.

If all that you are trying to do is to set the value of a text box when a button is clicked, then you can do it like in the following example. You’ll have to replace the names of the controls with whatever you have called them:

Private Sub Button1_Click(ByVal sender As Object, ByVal e As EventArgs) Handles Button1.Click
    Static count As Integer = 0
    count += 1
    Select Case count
        Case 1
            TextBox1.Text = "123"
        Case 2
            TextBox1.Text = "345"
    End Select
End Sub
