InfoPath Dev

I have a form that performs a specific task on form load.  This is working properly.  My question is, how do I disable/ignore this form load if I'm trying to open a submitted form.  I only need to run the below code on creation.

using Microsoft.Office.InfoPath;
using System;
using System.Xml;
using System.Xml.XPath;

namespace WorkOrder
{
    public partial class FormCode
    {
        // Member variables are not supported in browser-enabled forms.
        // Instead, write and read these values from the FormState
        // dictionary using code such as the following:
        //
        // private object _memberVariable
        // {
        //     get
        //     {
        //         return FormState["_memberVariable"];
        //     }
        //     set
        //     {
        //         FormState["_memberVariable"] = value;
        //     }
        // }

        // NOTE: The following procedure is required by Microsoft InfoPath.
        // It can be modified using Microsoft InfoPath.
        public void InternalStartup()
        {
            EventManager.FormEvents.Loading += new LoadingEventHandler(FormEvents_Loading);
        }

        public void FormEvents_Loading(object sender, LoadingEventArgs e)
            {
            // Be sure that the InputParameter dictionary contains
            // values before proceeding.
            bool FormEvents_Loading;
            if (e.InputParameters.Count != 0)
            {
                string vDate = e.InputParameters["Date"];
                string vCont = e.InputParameters["Cont"];
               
                XPathNavigator myNav = CreateNavigator();
                myNav.SelectSingleNode("/my:myFields/my:Reps/my:Contractor",NamespaceManager).SetValue(vCont);
                myNav.SelectSingleNode("/my:myFields/my:Service/my:Date", NamespaceManager).SetValue(vDate);
            }
        }
    }
}

Here's one simple thing you could do:

  public void FormEvents_Loading(object sender, LoadingEventArgs e)
            {
            // Be sure that the InputParameter dictionary contains
            // values before proceeding.
            bool FormEvents_Loading;

            if(this.New){
              if (e.InputParameters.Count != 0)
              {
                string vDate = e.InputParameters["Date"];
                string vCont = e.InputParameters["Cont"];
               
                XPathNavigator myNav = CreateNavigator();
                myNav.SelectSingleNode("/my:myFields/my:Reps/my:Contractor",NamespaceManager).SetValue(vCont);
                myNav.SelectSingleNode("/my:myFields/my:Service/my:Date", NamespaceManager).SetValue(vDate);
              }
           }
        }
