Introduction to BusinessProcess

We'll need to automatically iterate the data in the "Order_Details" table. For that we'll use a BusinessProcess

• Add a new item, based on the "BusinessProcess" template and call it "GetOrderStatistics"
• Add the Order_Details table to the controller, and set the Controller's From Property with that table.

using System;
using System.Collections.Generic;
using System.Text;
using System.Windows.Forms;
using Firefly.Box;
using ENV;
using ENV.Data;
using System.Diagnostics;

namespace Northwind.Training.SimpleScreen
{
    public class GetOrderStatistics : BusinessProcessBase
    {
        public readonly Models.Order_Details Order_Details = new Models.Order_Details();

        public GetOrderStatistics()
        {
            From = Order_Details;
        }
        public void Run()
        {
            Execute();
        }
    }
} 

• Note that you can remove it's public modifier, since we'll only use this table inside this controller.

public class GetOrderStatistics : BusinessProcessBase
{
-   public readonly Models.Order_Details Order_Details = new Models.Order_Details();
    readonly Models.Order_Details Order_Details = new Models.Order_Details();

    public GetOrderStatistics()
    {
        From = Order_Details;
    }
    public void Run()
    {
        Execute();
    }
} 

• Place a "Break Point" (using the F9 keyboard shortcut) on the call to Execute within the Run method, and run our controller
• Use the "Controllers" developer tool to run the 'GetOrderStatistics' BusinessProcess
• Visual studio will "Break" into the code and highlight our Execute method
  
• We'll add the Counter property to the "Watch" Window, to see how many rows get's processed
  
• We'll then press F10 to "Break" on next line, and we'll see that the value of Counter in the "Watch" window change to reflect the number of rows in the Order_Details table.
