C# textfile for license

[Siten0308]

Hello,

Simple but stuid question, i am working with this one guy right now, and he wants to be able to when the user installs a program and first launches the program to pop-up a box and notify the user that hey send this textfile to this email address to have the software work before using, anyone know how to do that or know a place that can do that? OR when a user goes to install the software using a wizard, it would be cool for the user to get a window or pop-up saying hey send this text file to this email address to get the software working... do you know anything on how to do that?

Uhh, I don't fully understand your question.
Do you want a textfile to be sent before the install wizard proceeds?

Can't you just write a while loop to prompt the user to send the text file and not proceed until the file is sent?

You can send emails by C# SmtpClient class. After sending mail you can write information that was sent in some property file or database. Each time when you start app you can check this file/db.
