Passing QueryString ID from aspx page to winform textbox

I am currently developing an aspx page that calls a winform. The issue at hand is passing the textbox variable from the web page, through the ProcessStartInfo event, to the winform textbox to retrieve an image. The viewer is from a vendor but is only applicable in a winform environment but the other information is coming from a CF page, to an href and to a nonfunctional web image viewer. Is what I am doing possible?

Aspx page code:

namespace ImageView
{
    public partial class _Default : System.Web.UI.Page
    {
        protected void page Load(object sender, EventArgs e)
        {
            TextBox1.Text = Request.QueryString["DKT_ID"].ToString();
            //TextBox2.Text = Request.QueryString["Name"].ToString();
            //TextBox3.Text = Request.QueryString["Age"].ToString();

ProcessStartInfo psi = new ProcessStartInfo(@"C:\ImageViewer\ImageView.exe");
            psi.WindowStyle = ProcessWindowStyle.Normal;

            Process p = new Process();
            p.EnableRaisingEvents = true;
            p.Exited += new EventHandler(MyExited);
            p.StartInfo = psi;
            p.Start();
        }

Winform code:

        //SQL section for returning images
        #region "Images Query"

        ImageQuery = "SELECT isn AS isn ";
        ImageQuery += "FROM bc_bcc_document (NOLOCK) ";
        ImageQuery += "WHERE barcode_id = ? ";

        DataTable Imagetable = new DataTable();
        Imagetable.Columns.Add("ISN", typeof(Int32));
        DataRow Imagerows;

        //fills table with Images information
        OdbcCommand comd = new OdbcCommand(ImageQuery);

        string conne = "Dsn=XXXX; uid=XXXXX; pwd=XXXXXX";

        using (OdbcConnection connected = new OdbcConnection(conne))
        {
            comd.Connection = connected;
            connected.Open();

            comd.Parameters.AddWithValue("barcode_id", txtBarcode.Text);

            OdbcDataReader readar = comd.ExecuteReader();

            while (readar.Read())
            {
                isn = Convert.ToInt32(readar["isn"].ToString().TrimEnd());
                Imagerows = Imagetable.NewRow();
                Imagerows["ISN"] = isn;
            }
            readar.Close();

Did you try to use ClickOnce? I think could be interesting, once if your client doesnt have that application installed, clickOnce will do install before start the application.

And you can pass args also.

Just pass the arguments from the web page like this

 var proc = new Process
 {
    EnableRaisingEvents = false,
    StartInfo = new ProcessStartInfo()
       {
           UseShellExecute = false,
           FileName = path,
           Arguments = Request.QueryString["DKT_ID"].ToString()
       }
  };
  proc.Start();

and read the command line arguments in your WinForms application like this -

string singleArgument = Environment.GetCommandLineArgs()[1];

P.S - assuming that you are passing a single argument, that's why Environment.GetCommandLineArgs()[1] is used because at [0]th position, you will get the path and [1]st position in the array would be useful to you.
