Lol, you think you can script in VB cuz you can do crap like that hehehe, thats RETARDED no offense I understand your trying to teach people something, but COME ON man, dont teach them the WRONG way to do it. Next thing you know, they will ask, what if I want MORE usernames and passwords, then you will be stuck telling them the "EASY" AND INEFFICIENT way of making more usernames, make a MASSIVE array and just tell them to do a for loop going through every element.
My simple explanation to all noobs:
The part that says If TextBox1.Text = "blabla" or w/e, learn how to use ADO.net ODBC and MySQL functionalities in VB, then get do an SQL query like
USE 'wargriderOwns'
"Select * from accounts where username = val1" (Val1 = TextBox1.Text)
If it returns negative, say you entered invalid, if it returns, open another form.
Thank for your time, and if you cant script a PROPER login form, then PLEASE dont show the wrong way.
