C# windows form, track user login : <p>I have three forms, signup ,login and after they have logged the dashboard will display their last edit on a text editor in C#. The project is an offline user login system, and not using any ASP. </p>

<p>I am thinking how to pass data after the user logs in in, so the form can retrieve and show data of that particular user. Everything is stored in a text file.</p>
