I have to verify the pfx file and get certificate details from the web base application but its not working after hosting the page in IIS, It only work on single machine.

-First I create an exe for the fetching the details but still its not working,

(exe saves the response in one table. And we want to fetch the response in the web Application. It is working through Code But After Hosting this is not working.)

I am fetching the data through creating the batch files.

like :

Please give me any suggestion or Idea for how to get the data from exe to web application. can any one have idea please tell me.

Thanks.

    {


        StringBuilder Script_Selparties = new StringBuilder();
        Script_Selparties.AppendLine("<script language='javascript'>");
        Script_Selparties.AppendLine("alert('1');");
        Script_Selparties.AppendLine("</script>");
        Page.ClientScript.RegisterStartupScript(this.GetType(), "", Script_Selparties.ToString());

        //Page.ClientScript.RegisterStartupScript(Me.GetType, "", Script_Selparties.ToString)
        String srcpathdCsdl = Server.MapPath("../CCRSDOCUMENTS");
        //X509Certificate2 X509Certificate2;
        String t1 = srcpathdCsdl + "/" + System.Configuration.ConfigurationManager.AppSettings["CertName"];

        //byte[] sig=Sign(bytes, x);

        ContentInfo content = new ContentInfo(bytes);

        SignedCms signedCms = new SignedCms(content, false);

        CmsSigner signer = new CmsSigner(SubjectIdentifierType.IssuerAndSerialNumber, x);


        // create the signature        

        signedCms.ComputeSignature(signer, false); // issue is here only
        //string Response1 = "1^webpart121112";
        //return Response1;

        // Send the data.
        newStream.Write(data, 0, data.Length);
        Console.WriteLine("Send");

        //Now, we read the response (the string), and output it.  
        HttpWebResponse WebResp = (HttpWebResponse)myRequest.GetResponse();
        Stream Answer = WebResp.GetResponseStream();
        StreamReader _Answer = new StreamReader(Answer);
        Console.WriteLine("Received");
        //var Response= _Answer.ReadToEnd();
        string Response = _Answer.ReadToEnd();
        newStream.Close();
        return Response;
    }

IS My Code which is Working fine in Code behind but not working after Hosting.
