[TUT]How to make a fake keygen - DeltaNox - Jan 30, 2010

I saw this question in another thread so I decided to make a tutorial for it. :)

I don't want to use the "Case method" I want to generate random numbers with capital letters on every click.

Like

0DK4-5KSE4-KE32-KU6RZ

But NOT the case method. I'd love to know how to do that..

Don't know if this is the most efficient method but it does the trick.

You need: 1 button (btnGenerate)
and 1 textbox (txtSerial)
Doubleclick the button you just added and add the following code.

1. Empty textbox first when button is pressed:

Code 
txtSerial.Text = ""

2. Declarations:

Code 
Dim x As Integer = 0

Dim i As Integer = 0

        Dim y As Boolean = False

        Dim Chars As Char() = "ABCDEFGHIJKLMNOPQRSTUVWXYZ0123456789".ToCharArray()

Dim rand As System.Random = New Random

Chars are the characters that will be generated, just add anything in there you want to appear into the fake serial.

3. Loop 1

Code 
For x = 0 To 3

This will set the lenght of your serial which will be xxxx-xxxx-xxxx-xxxx, if you want it to be something else then simply change the 3 to 4 or wathever you want it to be for example if you put for x = 0 to 5 then you'll be getting a serial like xxxx-xxxx-xxxx-xxxx-xxxx-xxxx

4. -

Code 
If y = True Then

                txtSerial.Text = txtSerial.Text & "-"

            End If

This will create the "-" except for the first loop.

5. Loop 2

Code 
For i = 0 To 3

                Dim intRandom As Integer = rand.Next(Chars.Length)

                txtSerial.Text = txtSerial.Text & Chars(intRandom).ToString()

            Next

This generates the random symbols and puts them into the textbox, the "for i = 0 to 3" wil create the lenght of each part of the code.

Finally add these two lines:

Code 
y = True

        Next

That's it. If you want to use seperate textboxes instead you can use this code:

Code 
TextBox0.Text = ""

        TextBox1.Text = ""

        TextBox2.Text = ""

        TextBox3.Text = ""

        Dim Chars As Char() = "ABCDEFGHIJKLMNOPQRSTUVWXYZ0123456789".ToCharArray()

        Dim rand As System.Random = New Random

        Dim i As Integer = 0

        For i = 0 To 3

            Dim text0 As Integer = rand.Next(Chars.Length)

            Dim text1 As Integer = rand.Next(Chars.Length)

            Dim text2 As Integer = rand.Next(Chars.Length)

            Dim text3 As Integer = rand.Next(Chars.Length)

            TextBox0.Text = TextBox0.Text & Chars(text0).ToString()

            TextBox1.Text = TextBox1.Text & Chars(text1).ToString()

            TextBox2.Text = TextBox2.Text & Chars(text2).ToString()

            TextBox3.Text = TextBox3.Text & Chars(text3).ToString()

        Next

This is much better than _void_'s fake keygen source.
Thanks for this! ^_^

nice TuT...

Mmmmm, i love arrays so much <3

Also, for all number keygen you can use rand for generating random numbers.

Bump (Seen a lot of requests for keygen codes).
