Simple Web Request

1. Open Visual Studio as Administrator
2. In Northwind project, create a new BussinessProcess named "WebDemo"
3. Add the following to the class:

namespace Northwind
{
    public class WebDemo : BusinessProcessBase
    {
        ENV.IO.WebWriter _ioRequester = new ENV.IO.WebWriter();

        public WebDemo()
        {
           Streams.Add(_ioRequester);
        }
        public void Run()
        {
           Exit(ExitTiming.AfterRow);
           Execute();
        }
    }
} 

WebWriter is an object that we use to work with the Web (Similar to Requester in Magic).
Streams is an object which is used to transfer the data.

4. In the OnStart, write a string back to the web page using the WebWriter

namespace Northwind
{
    public class WebDemo : BusinessProcessBase
    {
        ENV.IO.WebWriter _ioRequester = new ENV.IO.WebWriter();

        public WebDemo()
        {
           Streams.Add(_ioRequester);
        }
        public void Run()
        {
           Exit(ExitTiming.AfterRow);
           Execute();
        }
        protected override void OnStart()
        {
             _ioRequester.WriteLine("This is my first web page");
        }
    }
} 

5. In order to call this program from the web, it needs to have a unique identifier so we should create a public name for this program.
6. Go to the ApplicationPrograms.cs and add a new entry as follows:

namespace Northwind
{
    class ApplicationPrograms : ENV.ProgramCollection 
    {
        public ApplicationPrograms()
        {
            Add(3, "Show Customers", "", typeof(ShowCustomers));
            Add(4, "Show Products", "", typeof(ShowProducts));
            Add(5, "Show Orders", "", typeof(ShowOrders));
            Add(6, "Print - Order", "", typeof(Print_Order));
            Add(7, "Print - Orders", "", typeof(Print_Orders));
            Add("WebDemo", typeof(WebDemo));
            
        }
    }
} 

Notice that the first parameter is the public name.

7. Now, let’s configure the request URL.

Open the properties of the web project (Northwind.Server) and go to the "Web" tab.
The URL is a combination of Project Url option + Request.aspx?prgname=WebDemo (WebDemo is the unique public name and case sensitive) as follows:
http://localhost:61988/Request.aspx?prgname=WebDemo (Port number might be different in each computer)

8. Set the Web Project as your startup project (Right-Click on the project ->'Set as StartUP Project')
9. Build and run (click "Google Chrome" or "Internet Explorer")
