        in C Sharp
        First of all, thank you very much for replying to my topic. Actually I changed the code to use the button instead of barcode, it mentioned the error in line 74 which is FOR loop line seems doesn't catch the any thing from the database,

        for (int i = 0; i < dtable.Rows.Cou nt; i++)

        Code:
        private void button1_Click(object sender, EventArgs e)
        {
            try
            {

                                        by the way, actually the first code that I submitted in the first topic that will be in the login screen and I can't pass the login and password in the tool bar of the browser so I'm using POST instead of get because it's much secure. I tried your code but I used POST but couldn't get the username.

                                        So what should I do?
