hope this fix your issue
You're creating three instances of Form1, I don't think that's intentional.
code :
private void button1_Click(object sender, EventArgs e)
{
    var nextForm = new Form1();
    nextForm.Text1 = comboBox2.Text;
    nextForm.Text2 = comboBox1.Text;
    nextForm.Text3 = textBox1.Text;

    string selectedUser = this.comboBox1.GetItemText(this.comboBox1.SelectedItem);

    if ((selectedUser == "admin") && (textBox1.Text == "password"))
    {
        nextForm.Show();
        nextForm.Activate();
        this.Hide();
    }
}

JS: Fetch string from array that matches line in form-input

JS: Fetch string from array that matches line in form-input

wish of those help I have a form with a text-input and a submit button. In the text-input you write simple commands like /look (creating a simple game, to try out and improve my skills). In a .js-file I have an array of a few commands/strings. , You almost have it right,
Heres what i did.
code :
<script type="text/javascript">
        function commands(form)
    {
        var str = form.command.value;
       var charCommand=new Array(); // regular array (add an optional integer
        charCommand[0]="/look";       // argument to control array's size)
        charCommand[1]="/use";
        charCommand[2]="/continue";
        charCommand[3]="/pickup";

        for(i=0 ; i < charCommand.length ; i++)
    {
        if(str.match(charCommand[i]))
            {
                document.getElementById("commandField").innerHTML=charCommand[i];
            }
    }
    }



    </script>
    </head>
    <body>
        <div id="commandField">
            <form method="GET" action="">
                <p class="center">Command: <input type="text" name="command" class="command" />
                <input type="button" value="Execute" onClick="commands(this.form)"/></p>
            </form>
        </div>
    </body>
    </html>

I hope this helps you . The format string you specified is not correct. The month and day fields are in wrong place (That need to be interchanged).
You need to change that to:
code :
[dateFormatter setDateFormat:@"yyyy-MM-dd HH:mm:ss"];

I wish did fix the issue. Could you please add the formatted stack trace.
Number of arguments might be the issue.
code :
JOptionPane.showInputDialog(null, " " , "txt");
