Generate Barcode in windows application

Let's take a look step by step.

Step 1: Download QRCODE GENERATOR LIBRARY from onbarcode.com.

Step 2: Open Visual Studio - Create New Project - Windows Form.

Step 3: Add reference to OnBarcode.Barcode.Winforms.dll.

Step 4: Design form with some input fields for accepting data to encode and the targeted location to save barcode generated image.

Step 5: To generate Barcode as well as Qrcode images write two differen methods as follows. 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 OnBarcode.Barcode;

using System.Drawing.Imaging;

namespace DRAWBARCODEAPP

{

    public partial class Form1 : Form

    {

        public Form1()

        {

            InitializeComponent();

        }

        private void Form1_Load(object sender, EventArgs e)

        {

           

        }

        private void GenerateQrcode(string _data, string _filename)

        {

            QRCode qrcode = new QRCode();

            qrcode.Data = _data;

            qrcode.DataMode = QRCodeDataMode.Byte;

            qrcode.UOM = UnitOfMeasure.PIXEL;

            qrcode.X = 3;

            qrcode.LeftMargin = 0;

            qrcode.RightMargin = 0;

            qrcode.TopMargin = 0;

            qrcode.BottomMargin = 0;

            qrcode.Resolution = 72;

            qrcode.Rotate = Rotate.Rotate0;

            qrcode.ImageFormat = ImageFormat.Gif;

            qrcode.drawBarcode(_filename);

        }

        private void GenerateBacode(string _data, string _filename)

        {

            Linear barcode = new Linear();

            barcode.Type = BarcodeType.CODE11;

            barcode.Data = _data;

            barcode.drawBarcode(_filename);

        }

        private void Form1_Load_1(object sender, EventArgs e)

        {

           

        }

        private void button1_Click(object sender, EventArgs e)

        {

            SaveFileDialog sfd = new SaveFileDialog();

            sfd.ShowDialog();

            textBox2.Text = sfd.FileName.ToString()+".gif";

        }

        private void button2_Click(object sender, EventArgs e)

        {

            GenerateBacode(textBox1.Text, textBox2.Text);

        }

        private void button3_Click(object sender, EventArgs e)

        {

            GenerateQrcode(textBox1.Text, textBox2.Text);

        }

    }

}

Now Take look on the Windows form:-
