This article describes how to use Microsoft Collaboration Data Objects (CDO) for Windows 2000 library (Cdosys.dll) to act on a message. This article describes how to act on a message in Microsoft Visual C# .NET or Microsoft Visual C# 2005.
To act on a message, you can do any one of the following:
| You can click Reply. |
| You can click Reply All. |
| You can click Forward. |
Note The Cdosys.dll library is also known as CDOSYS.
To use CDOSYS to act on a message, follow these steps:
| 1. | Start Microsoft Visual Studio .NET or Microsoft Visual C# 2005. |
| 2. | On the File menu, click New, and then click Project. |
| 3. | Click Console Application in the Visual C# Projects types list.
Note In Microsoft Visual C# 2005, click Console Application in the Visual C# 2005 list.
In Visual Studio .NET, Class1.cs is created by default. In Visual Studio 2005, Program.cs is created by default. |
| 4. | Add a reference to the Microsoft CDO For Windows 2000 Library.
To do this, follow these steps:| a. | On the Project menu, click Add Reference. | | b. | On the COM tab, click Microsoft CDO For Windows 2000 Library, and then click Select.
Note In Visual Studio 2005, you do not have to click Select. | | c. | In the Add References dialog box, click OK to accept your selections.
If you receive a message to generate wrappers for the libraries that you selected, click Yes. |
|
| 5. | In the Code window, replace all the code with the following code:
namespace CdoSys
{
using System;
class Class1
{
static void Main(string[] args)
{
try
{
CDO.DropDirectory iDropDir = new CDO.DropDirectory();
CDO.IMessages iMsgs;
CDO.IMessage iMsgReply;
CDO.IMessage iMsgReplyAll;
CDO.IMessage iMsgForward;
// Get the messages from the Drop directory.
iMsgs = iDropDir.GetMessages("C:\\Inetpub\\mailroot\\Drop");
Console.WriteLine("Messages Count : " + iMsgs.Count.ToString());
foreach (CDO.IMessage iMsg in iMsgs)
{
Console.WriteLine(iMsgs.get_FileName(iMsg));
// Output some common properties of the extracted message.
Console.WriteLine("Subject: " + iMsg.Subject);
Console.WriteLine("TextBody: " + iMsg.TextBody);
Console.WriteLine("datereceived: " + iMsg.Fields["urn:schemas:httpmail:datereceived"].Value);
Console.WriteLine("sendername: " + iMsg.Fields["urn:schemas:httpmail:sendername"].Value);
Console.WriteLine("senderemail: " + iMsg.Fields["urn:schemas:httpmail:senderemail"].Value);
Console.WriteLine("from: " + iMsg.Fields["urn:schemas:httpmail:from"].Value);
Console.WriteLine("sender: " + iMsg.Fields["urn:schemas:httpmail:sender"].Value);
// Reply.
iMsgReply = iMsg.Reply();
// TODO: Change "rhaddock@northwindtraders.com" to your e-mail address.
iMsgReply.From = "rhaddock@northwindtraders.com";
iMsgReply.TextBody = "I agree. You can continue." + "\n\n" + iMsgReply.TextBody;
iMsgReply.Send();
// This is ReplyAll.
iMsgReplyAll = iMsg.ReplyAll();
// TODO: Change "rhaddock@northwindtraders.com" to your e-mail address.
iMsgReplyAll.From = "rhaddock@northwindtraders.com";
iMsgReplyAll.TextBody = "I agree. You can continue" + "\n\n" + iMsgReplyAll.TextBody;
iMsgReplyAll.Send();
// This is Forward.
iMsgForward = iMsg.Forward();
// TODO: Change "rhaddock@northwindtraders.com" to your e-mail address.
iMsgForward.From = "rhaddock@northwindtraders.com";
// TODO: Change "Jonathan@northwindtraders.com" to the address that you want to forward to.
iMsgForward.To = "Jonathan@northwindtraders.com";
iMsgForward.TextBody = "You missed this." + "\n\n" + iMsgForward.TextBody;
iMsgForward.Send();
}
// Clean up memory.
iMsgs = null;
iMsgReply = null;
iMsgReplyAll = null;
iMsgForward = null;
}
catch (Exception e)
{
Console.WriteLine("{0} Exception caught.", e);
}
return;
}
}
