PurchaseId autogenerate number

How can I autogenerate the PurchaseId?

 

I am following a tutorial from here: http://www.tandasoft.com/2011/05/05/using-authorize-net-dpm-direct-post-method-from-asp-net-web-form...

 

This part is trying to grab a PurchaseId from somewhere (unknown to me as to where), but I just want to have my application create the id automatically for me.

 

 if (Session["PurchaseID"] != null)
        {
            nPurchaseID = (Int32)Session["PurchaseID"];
        }
        else
        {
            // You might throw here, but this is just an example, so assign a bogus PurchaseID
            nPurchaseID = 1;
        }

 

Here is my full code here:

 

protected void Page_Load(object sender, System.EventArgs e)
    {
        // In my application, I've already written the pending purchase to the database 
        // and assigned an ID before redirecting to this page.
        if (Session["PurchaseID"] != null)
        {
            nPurchaseID = (Int32)Session["PurchaseID"];
        }
        else
        {
            // You might throw here, but this is just an example, so assign a bogus PurchaseID
            nPurchaseID = 1;
        }

        // This is the way we get a Web Forms app to post to a different URL...
        btnSubmit.PostBackUrl = "https://test.authorize.net/gateway/transact.dll";

        strAuthorizeNet_x_amount = "175.00";
        strAuthorizeNet_x_login = ConfigurationManager.AppSettings["AUTHORIZE_NET_API_LOGIN"];
        strAuthorizeNet_x_first_name = "John";
        strAuthorizeNet_x_last_name = "Doe";
        strAuthorizeNet_x_address = "123 Main St";
        strAuthorizeNet_x_city = "Anywhere";
        strAuthorizeNet_x_state = "CO";
        strAuthorizeNet_x_zip = "12345";

        strAuthorizeNet_x_fp_timestamp = AuthorizeNet.Crypto.GenerateTimestamp().ToString();
        strAuthorizeNet_x_fp_sequence = AuthorizeNet.Crypto.GenerateSequence();
        strAuthorizeNet_x_relay_response = "TRUE";
        strAuthorizeNet_x_test_request = "TRUE";
        strAuthorizeNet_x_fp_hash = AuthorizeNet.Crypto.GenerateFingerprint(ConfigurationManager.AppSettings["AUTHORIZE_NET_TRANSACTION_KEY"], strAuthorizeNet_x_login, decimal.Parse(strAuthorizeNet_x_amount), strAuthorizeNet_x_fp_sequence, strAuthorizeNet_x_fp_timestamp);

        // CRITICALLY IMPORTANT: This link must direct to your SIM.aspx page, and MUST be accessible... 
        //                       it will NOT work if your test/development web server is behind a firewall!!
        //                       Also, if you use https, make sure your SSL certificate is signed and valid 
        //                       or Authorize.NET will reject the URL.
        strAuthorizeNet_x_relay_url = ConfigurationManager.AppSettings["MainWebURL"] + "SIM.aspx";

        // I'm not certain authorize.net will ever utilize this link...  Authorize.NET simply hits your 
        // x_relay_url and relays the response contents to the client's browser.  See SIM.aspx 
        // for more details.
        strAuthorizeNet_x_receipt_link_url = ConfigurationManager.AppSettings["MainWebURL"] + "Thanks.aspx";
