Interfacing with COM

[Marco Shaw]

**Programming newbie**

I'd like to write some C# that interacts with a COM object ("automation
library"?). I don't quite know what to look for though to find examples.

I'm guessing if I can find some demos of C# using COM objects like that from
MS Office, that might get me started?

Hi Marco,
If you reference a dll in your project .net creates an Interop wrapper that
lets you interact with it.
regarding Office you reference the Office PIAs (Primary Interop Assemblies)
these can be downloaded from Microsoft.

I have had a quick play but haven't done anything substantial.
Play code follows:

using System;

using System.Collections.Generic;

using System.ComponentModel;

using System.Data;

using System.Drawing;

using System.Text;

using System.Windows.Forms;

using Outlook = Microsoft.Office.Interop.Outlook;

namespace TestOutLookPIA

{

public partial class Form1 : Form

{

private Outlook.Application outlook;

public Form1()

{

InitializeComponent();

outlook = new Outlook.ApplicationClass();

outlook.GetNamespace("MAPI");

Outlook.MailItem myMail;

myMail=(Outlook.MailItem)outlook.CreateItem(Microsoft.Office.Interop.Outlook.OlItemType.olMailItem);

myMail.Recipients.Add([email protected]);

myMail.Body = "Test Message";

myMail.Subject = "Test Mail";

myMail.Send();


}

}

}
