Making a simple Key Generator.

Alright, I am going to make a short guide explaining how to make a key generator. I will only be explaining the basic functions.

First. This Is my finished Key Generator that I created about 20 minutes ago.

Here is my code.

Public Class Form1


    Private Sub Label1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs)


    End Sub


    Private Sub GroupBox1_Enter(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles GroupBox1.Enter


    End Sub


    Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button1.Click

        If txtbox1.Text = txtboxa1.Text And txtbox2.Text = txtboxb1.Text And txtbox3.Text = txtboxc1.Text And txtbox4.Text = txtboxd1.Text Then

            lbl1.Text = "Key"

            lbl1.Text &= " Correct"

        Else

            lbl1.Text = "Key"

            lbl1.Text &= " Incorrect"

        End If

    End Sub


    Private Sub Button2_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button2.Click

        Dim rnd As New Random

        txtboxa1.Clear()

        txtboxb1.Clear()

        txtboxc1.Clear()

        txtboxd1.Clear()

        For i As Integer = 0 To 3

            txtboxa1.Text &= rnd.Next(0, 9)

            txtboxb1.Text &= rnd.Next(0, 9)

            txtboxc1.Text &= rnd.Next(0, 9)

            txtboxd1.Text &= rnd.Next(0, 9)

        Next

    End Sub


    Private Sub TextBox4_TextChanged(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles txtbox4.TextChanged


    End Sub


    Private Sub Label7_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles lbl1.Click


    End Sub


    Private Sub txtbox1_TextChanged(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles txtbox1.TextChanged


    End Sub

End Class

Basically, .text means it is the text inside of the selected item. So if we create a text box and we want to deal with the property text we would take the name of a textbox which would be textboxname.text and modify what we want. Because VB is such a basic program and is also a very advanced program as well you can make many many useful things. From a simple login box to a multi media GUI that is sold around the world.
