Free DLL to generate image barcodes

Hi guys!

I have developed this simple dll for the barcode printing / representation, the use is very simple :

1

 

 

this is the code of the sample form:

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 BarcodeFree;

namespace WindowsFormsApplication1
{
    public partial class Form1 : Form
    {
        public Form1()
        {
            InitializeComponent();
        }

        private void button1_Click(object sender, EventArgs e)
        {
           Code128 text = new Code128();
            this.textBox2.Text = text.Encode( textBox1.Text);
            ImageBarcode barcode, barcode2, barcode3, barcode4;
            //parameters to call ImageBarcode:
            //public ImageBarcode(int width, int height, string value, bool Landscape = false, Color? color = null,Color? colorFore=null )
        
            barcode = new ImageBarcode(pictureBox1.Width, pictureBox1.Height, textBox2.Text);
            barcode2 = new ImageBarcode(pictureBox2.Width, pictureBox2.Height, textBox2.Text, false, Color.Red, Color.Yellow );
            barcode3 = new ImageBarcode(pictureBox3.Width, pictureBox3.Height, textBox2.Text, true);
            barcode4 = new ImageBarcode(pictureBox4.Width, pictureBox4.Height, textBox2.Text, false, Color.Turquoise , Color.LightGray);
//            barcode = new ImageBarcode(250, 112, textBox2.Text);
            this.pictureBox1.Image = barcode.GenerateImage();
            this.pictureBox2.Image = barcode2.GenerateImage();
            this.pictureBox3.Image = barcode3.GenerateImage();
            this.pictureBox4.Image = barcode4.GenerateImage();
//            this.pictureBox1.Refresh();
        }
    }
}

And Finally the DLL( for demo test):

/images/BarcodeFree.dll

How to make an ajax call inside a WordPress site

After several days, finally I found how to make ajax call from my wordpress site, I hope that it will help those who have had this problem:

first, I was created a post inside a wordpress whit this html code:

<section id="main">
    <table id="tng" class="datagrid">
    	<thead><tr><th colspan="3"> 
            Sample ping App
            </th>
        </thead>
        <tbody>
    	</tr><tr>
    		<td width="50%" align="right"><b>Host or IP:</b></td>
    		<td><input  id="ip" size="20" value="" ></td>
                <td><button type="button" onclick="PING()">Ping</button></td>
    	</tr>
        </tbody>
    </table>
    <img id="image" src="spinner.gif" alt="wait..." style="display: none;">
    <br>
    
</section>	
<section id=food>
	<h3 id="notification"></h3>
</section>

As you can see the only important thing is the onclick event for the button that calls de functionPING()
