   using System;
   using SMP101Windows;
   using System.Windows.Forms;
   
   namespace SMP101Windows
   {
       static class Program
       {
           /// <summary>
           /// The main entry point for the application.
           /// </summary>private static Customers _form1 = new Form1();
           private static Customers _form1 = new Customers();
           private static Customer_Details _form2 = new Customer_Details();
           private static string _custid;
           public static string getCustomer()
           {
               return _custid;
           }
           public static void setCustomer(string custid)
           {
               _custid = custid;
           }
           public static Customers getForm1()
           {
               return _form1;
           }
           public static Customer_Details getForm2()
           {
               return _form2;
           }
           static void Main(string[] args)
           {
               Application.Run(_form1);
           }
