Open a pdf document in a aspx page

Question

Hi Experts

I am trying to open a pdf document in a aspx page but i dont know what is the mistake i made in the following code.

   string Path = Request.QueryString["Path"];
        if (File.Exists(Path.Replace("pdf", "txt")))
        {
            FileStream fs = null;
            try
            {
                fs = File.Open(Path, FileMode.Open, FileAccess.ReadWrite, FileShare.None);
            }
            catch (IOException)
            {
            }
            bool canRead = fs.CanRead;
            if (canRead)
            {
                fs.Close();
                Response.Write("<script>window.open('file:" + Path.Replace("\\", "/") + "')'</script>");
            }
        }
        else
            Response.Write("<script>alert('Document has not been created yet'); </script>");




In the above code there are two problems
1) I could not show the pdf document on the page
2) In the else loop if the document doesnot exist then i need to display the message and close the current page.



Any ideas??????????
