Login Form in Csharp Using ProgressBar

In this article we will know a login page using a progress bar control. When user gives both the credentials (user id & password) values correctly, then a new form will display showing login success.

Table structure

Create a database in Ms-access as below.

Program

Add two forms in the application.

using System;

using System.Collections.Generic;

using System.ComponentModel;

using System.Data;

using System.Drawing;

using System.Linq;

using System.Text;

using System.Windows.Forms;

using System.Data.OleDb;

namespace Login_Form_in_Csharp_Using_ProgressBar

{

    public partial class Form1 : Form

    {

        string ConnectionString = System.Configuration.ConfigurationSettings.AppSettings["dsn"];

        OleDbCommand com;

        OleDbDataAdapter oledbda;

        DataSet ds;

        string str;

        public Form1()

        {

            InitializeComponent();

        }

        private void btnlogin_Click(object sender, EventArgs e)

        {

            if (txtusername.Text == "" || txtpassword.Text == "")

            {

                MessageBox.Show("Please enter User ID or Password");

                txtusername.Text = "";

                txtpassword.Text = "";

            }

            else

            {

                OleDbConnection con = new OleDbConnection(ConnectionString);

                con.Open();

                str = "select count(*) from login where userid='" + txtusername.Text.Trim() + "' and password='" + txtpassword.Text.Trim() + "'";

                com = new OleDbCommand(str, con);

                oledbda = new OleDbDataAdapter(com);

                ds = new DataSet();

                oledbda.Fill(ds, "login");

                long x;

                x = Convert.ToInt64(com.ExecuteScalar());

                if (x == 1)

                {

                    int y = 0;

                    progressBar1.Visible = true;

                    progressBar1.Minimum = 1;

                    progressBar1.Maximum = 100000;

                    progressBar1.Value = 1;

                    progressBar1.Step = 1;

                    for (y = 1; y <= 100000; y++)

                    {

                        progressBar1.PerformStep();

                    }

                    Form2 f1 = new Form2();

                    f1.Show();

                    this.Hide();

                }

                else

                {

                    MessageBox.Show("Invalid User ID or Password! Try Again!");

                    txtusername.Text = "";

                    txtpassword.Text = "";

                }

                con.Close();

            }        

        }

    }

}

Output
