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

                label4.Text = m;

    }
}

<?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.
