Reading from text files

[Adrammelech]

Im pretty new to vb.net and im writing a simple RPG. Where I'm having a problem is the signin form. I have a create a character form that saves all the varibles in a text file like "Name Password Level..." But I dont know how to let me sign it with any of the names I created. Basically, I dont know how to get it where if I type a name and password, it searches the text file for the corresponding name and password, and If it finds it, it signs in with it. Now, I have to create a character each time I want to sign it.
