Friend, Give You Simple Idea Create registry Key When you Install Software write Serial In Registry and Compare it Every time when Software is Loaded if its True Software Will run else Will ask you For Serial .. First of All make your Setup Project Capable to Create Entry in HKEY_CURRENTUSER like Below Its not Complete Code But Just Code that i have Writen to Show you Example How to Code for Registry using Microsoft.Win32; private void Form1_Load( object sender, EventArgs e) { RegistryKey regkey = Registry.CurrentUser.OpenSubKey( @"Softwares\CompanyName\", true); string Serial = regkey.GetValue(" AppSerial "," ").ToString(); regkey.Close(); if (Serial != " YourCustome generated Serial") { // Show Serial Validation Dialog SerialDialog sd = new SerialDialog(); SerialDialog.ShowDialog(); //Now Write Code For Form Closing if User Gives Wrong Serial number !! } }
