using System.Windows.Forms;
using System.Speech.Synthesis;
using System.Xml;

namespace MyIEAddon1
    public partial class Form1 : Form
        public Form1()

        private void button3_Click(object sender, EventArgs e)
            SpeechSynthesizer audio = new SpeechSynthesizer();// repeat what i say in computer speech
            if (textBox1.Text == "" | textBox1.Text == " " | textBox1.Text == "  " | textBox1.Text == null)
                MessageBox.Show("No word entered, Please enter your word ", "Error Message");

            {// (!string.IsNullOrEmpty(textBox1.Text))   // (listBox1.Items.Contains(textBox1.Text))

                if (!string.IsNullOrEmpty(textBox1.Text) && listBox1.Items.OfType<string>().Select(p => p.ToUpper()).Contains(textBox1.Text.ToUpper()))  // 
                    MessageBox.Show("Sorry, Word that you try to add is already on the XML file", "Error Message");
                    textBox1.Text = " ";

                textBox1.Text = "";


        private void button5_Click(object sender, EventArgs e)
            button4.Enabled = true; // disable save xml file
            button5.Enabled = false; //  enable load grammar to load grammar from xml file
            button3.Enabled = true; //  disable add button  

            XmlTextReader reader = new XmlTextReader("Grammar.xml");
            XmlNodeType type;

            while (reader.Read())
                type = reader.NodeType;

                if (type == XmlNodeType.Element)

                    if (reader.Name == "item")



        private void button4_Click(object sender, EventArgs e)
            button5.Enabled = false; // disable load xml file
            button4.Enabled = true;  // enable save xml file

                XmlTextWriter writer = new XmlTextWriter("Grammar.xml", Encoding.UTF8);
                writer.Formatting = Formatting.Indented;

                writer.WriteAttributeString("xmlns", "http://www.w3.org/2001/06/grammar");
                writer.WriteAttributeString("xmlns:xsi", "http://www.w3.org/2001/XMLSchema-instance");
                writer.WriteAttributeString("xml:lang", "en-US");
                writer.WriteAttributeString("version", "1.0");
                writer.WriteAttributeString("root", "command1");
                writer.WriteStartElement("rule ");
                writer.WriteAttributeString("id", "command1");
                writer.WriteAttributeString("scope", "public");

                foreach (string item in listBox1.Items)
                    writer.WriteEndElement(); //WORD

                writer.WriteEndElement(); //COMMAND
                writer.WriteEndDocument();// End Document

                MessageBox.Show("THE NEW WORDS ADD TO THE XML FILE !!", "Message");
            { MessageBox.Show("InvalidCastException"); }

            int num = listBox1.Items.Count;  //  to count tne number of words will do the folowing :
            string m;
            m = Convert.ToString(num);

            foreach (string item in listBox1.Items)

                label4.Text = m;

this is my xml file

<?xml version="1.0" encoding="utf-8"?>
<grammar xmlns="http://www.w3.org/2001/06/grammar" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xml:lang="en-US" version="1.0" root="command1">

Hello Samar,

I cannot say that I understand what you do or what occurs. It looks like you create a file and get an exception. First off, you need to read the description of the method that opens the file and modify your installer so that it places the XML to a location where your add-on can find it. Also, please read HowTo: Deal with Protected Mode API in Internet Explorer 7 and IE8 at http://www.add-in-express.com/creating-addins-blog/2009/06/12/internet-explorer-protected-mode-api/.

You should understand that IE will create many instances of your IE add-on. So you must be prepared that several instances of your form will be shown. Please read the section "Windowing and Threading" in the manual, see {Add-in Express}\Docs\adxie.pdf.

Also, I suggest that you consider usin an ADX IE Bar to show your controls, not just System.Windows.Forms.Form. The fact is that non-modal forms interfere with the windowing of IE. Please have a look into the manual, the section is Custom Bars in IE.
