  9. At 8:40 when i press ctl+s instead of showing a dialoge box that shows in the video like choose name,
     my PC asks to saves the file in my documents or in local disk drive instead of saving it in visual studio like a dialoge box has appeared for the name of the table. Please can someone help. Please.

  10. God, don’t do this at your job; you will be fired for it.
    Possibly beating and pushed down an elevator shaft.

    This is just a ‘lookup form’. No hashing which would have taken 30 seconds to add. No lockout policy. No nothing related to a login form.
    This could easily be a search form instead. Well, that is all it is.

    Hash the password. Sha256 or better, at least. Then the database at least requires effort to guess the password. Also, count bad login attempts, a column in the database. Also track the last login date and time, and the last login attempt date and time. Just as easily you could track the IP address or the computer name or some metrics of who is trying to login in order to track down a hacker. Obviously frameworks exist for all of these interfaces like Windows forms or a.net Mvc website or a web forms website. Frameworks also exist for PHP and other shit.

    But seriously just adding a couple fields and at least cashing it would make it a legitimate login for me. All this is doing right now is this matching to text Fields in the database as a search

  11. i am new to c# so can someone say me what i must put in this string query = "Select * from tbl_Login Where username = '" + txtUsername.Text.Trim() + "' and password = '" + txtPassword.Text.Trim() + "'";
