Serial Number System

An extremely basic serial number and HWID lock system for selling VB.NET and C# programs!

5.4289235e+26 total serial keys

Setup

SQL

Enter PHPMyAdmin, make a new database named "serial".

Click on the "SQL" tab and enter

CREATE TABLE `serial`.`serial`(
    `id` INT NOT NULL AUTO_INCREMENT,
    `serial` VARCHAR NOT NULL,
    `hwid` VARCHAR NOT NULL,
    PRIMARY KEY(`id`)
) ENGINE = InnoDB;

then hit "Go"

Web Files

Edit serialcheck.php from

$link = mysqli_connect('localhost','root','');
$database = mysqli_select_db($link,'serial');

to match your SQL login! (Example)

$link = mysqli_connect('localhost','user','password');
$database = mysqli_select_db($link,'serial');

Now edit generateserial.php

$servername = "localhost";
$username = "root";
$password = "";
$dbname = "serial";

(Yes I know 2 different login forms is trash but whatever.

Application

Edit line 81 and 122 from

WebBrowser1.Navigate("http://localhost/serial/serialcheck.php?serial=" + TextBox1.Text + "&hwidin=" + TextBox2.Text + "&submit=Submit")

To

WebBrowser1.Navigate("http://YOURDOMAINGOESHERE.com/PATH/TO/serialcheck.php?serial=" + TextBox1.Text + "&hwidin=" + TextBox2.Text + "&submit=Submit")

Finally, edit lines 99-106 to be something like:

            ElseIf (WebBrowser1.DocumentText.Contains("1")) Then
                check = 0
                Button1.Enabled = True
                My.Settings.Installed = True
                My.Settings.Serial = TextBox1.Text
                My.Settings.Save()
                Timer1.Stop()
                Form2.Show()

And build your program on Form2

Best of luck!
