Script Protection

[XRS]

Hello.

I've almost finished my script and I want to protect it a simple way.

I don't want users pay it for or something else.

Let's give an example.

I have an application that makes a login to a website (with username and password)

I want that the script, when user insert user and pass, read a serverside file (logins.txt) and check if inputed user is there.

If so, the app continues, if not, shows a MSGBox and exit.

The txt file with usernames should be this way:

user1

user2

user3

Can someone help me how to get this?

This seems to be the easiest mode to protect my app.

Maybe below code could help you to accomplish your goal:

$sUser="userX" ;Or whatever method you are using to get the user name
$sLoginText="http://yourdomain.tld/logins.txt"
$sInetRead=BinaryToString(InetRead($sLoginText,1))
$iChecking=StringRegExp($sInetRead,"\Q" & $sUser & "\E")
If $iChecking=0 Then
    MsgBox(16,"Sorry but...","The user " & $sUser & " is not authorized to use this application")
    Exit
EndIf
;If user matches then continue...

Cheers,
