Hi Victor,

Thank you for your update.

Is the web application you navigate in IE and in your windows application
written by yourself?  If yes, would you please send the web application
project to me for research?

When you navigate the web pages in your windows application and click on a
link to open a new window, is the new window a new windows form in your
windows application or a new IE instance?

To get my actual email address, please remove the "online" from my
displayed email address.

I appreciate your cooperation and look forward to your reply.

Sincerely,
Linda Liu

Hello Victor,

I may not undertsand the problem exactly. But I didn't agree what you said
session about an ASP.NET appliaction. If you rasie a new IE instance
(Start/All Programs/Internet Explorer), a session wil start; If we open a
new IE window from a original one (File/New/Window), it will share the
original session. For Web browser control, it just like we open a new IE
instance, and start a new session. For example, you test following ASP.NET
with IE:

protected void Page_Load(object sender, EventArgs e)
   {
       if (Session["Test"] == null)
           Session["Test"] = "New";
       else
           Session["Test"] = "old";

       Response.Write(Session["Test"]);  
   }
