This may seem idiotic but, i think u can use the computer's IP instead of the modem one OR you can make the program to make a file and check if it exists

The first one seems okay, wht if they re-format their computer? And the second one could easily be found out.

[upperdrag]

When they reformat they should know that all of the programs is gone so......... lmao; and u can hide the file in a very very very very very very hidden place and lock it up using the file locker

[Lewis]

What if they restore the program :/ And the file locker means it wont be readable it can be seen and recreated, The way to go is web or mysql

[Kieken72]

Try something With MySql, or something, like Username and password and a serial

[Livengood]

you could have it make a file somewhere on the C:/ and have it read the key and things..... for the login

[NoWayIn]

use MySQL to store the data such as Computer Names, IP, and ID
Use PHP with VB to check for the data

My method will guarantee, best than others.
Set up a website with a file manager( uCoz is a great choice )
You login to your website(e.g.: http://www.musicboxdotnet.at.ua , under Control > File Manager)
You upload a html file with your serial key as the body, title as anything you want.

*When someone purchase a license for your program :
Before you sent them the serial, edit the html file's tite to "USED"
When they activate the program, use a web browser, etc.
Code :

Code: Select all

WebBrowser1.Navigate("YourWebsite.com/YourSerialFile.html")

Under WebBrowser1.DocumentCompleted

Code: Select all

If not WebBrowser1.DocumentTitle = "Used" then
 Elseif not WebBrowser1.DocumentTitle = "404" then
Msgbox "Activate Success"
else
msgbox "You FAIL Over 9000000 Times, You FAIL on LIFE"
End If

Before you use the code, make sure your "client" has an internet connection, or add

Code: Select all

Elseif WebBrowser1.Documenttitle = <IE / FF / Chrome Error Page>

Behind

Code: Select all

Elseif not WebBrowser1.DocumentTitle = "404" then

To use a key they must be a way for when that key is used it cant be used again - Use Php script on a website.

That's exactly like on Steam, if you buy a steam game you cannot use the serial key again :P

you can try with IP... (but it will work on any computer with same IP)
