Password Protection Using Code in Windows Forms

Here, I will explain how to do password protection in code. Before that, I suggest you see the explanation in Tutorial 2 Creating Login Form with SQL Server in Windows Forms.

Step 1. Create a login form

First, create a Login form as I showed in Tutorial 2.

Step 2. Coding

using System;
using System.Collections.Generic;
using System.ComponentModel;
using System.Data;
using System.Drawing;
using System.Text;
using System.Windows.Forms;
using System.Data.SqlClient;

namespace First_Csharp_app
{
    public partial class Form1 : Form
    {
        public Form1()
        {
            InitializeComponent();
            pass_txt.PasswordChar = '$'; // Without this, you can also set it using the textbox property "UseSystemPasswordChar".
        }

        private void button1_Click(object sender, EventArgs e)
        {
            // Your coding logic here
        }
    }
}
