How to use the Cdosys.dll library to embed a message in a new message by using Visual C#
This article was previously published under Q310221
This article describes how to use the Microsoft Collaboration Data Objects (CDO) for Windows 2000 library (Cdosys.dll) to embed a message in a new message. You can do this by using Microsoft Visual C#.
Note The Cdosys.dll library is also known as CDOSYS.
To use CDOSYS to embed a message in a new message, follow these steps:
- Start Microsoft Visual Studio .NET or Microsoft Visual Studio 2005.
- On the File menu, click New, and then click Project.
- Click Console Application in the Visual C# Projects types list.
By default, Class1.cs is created.
Note In Microsoft Visual C# 2005, you must click Console Application in the Visual C# list. By default, Program.cs is created. - Add a reference to the Microsoft CDO For Windows 2000 Library. To do this, follow these steps:
- On the Project menu, click Add Reference.
- On the COM tab, locate Microsoft CDO For Windows 2000 Library, and then click Select.
Note In Microsoft Visual C# 2005, you do not have to click Select. - 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 select, click Yes.
- 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.IBodyPart iBp;
CDO.IMessage iEmbdded;
CDO.Message oMsg;
CDO.IDataSource iDsrc;
// Create a new message.
oMsg = new CDO.Message();
oMsg.From = "rhaddock@northwindtraders.com";
oMsg.To = "rhaddock@northwindtraders.com";
oMsg.Subject = "CDOSYS Send mail";
oMsg.TextBody = "Hello";
iBp = oMsg.BodyPart.AddBodyPart(-1);
// Embed the message.
iMsgs = iDropDir.GetMessages("C:\\Inetpub\\mailroot\\Drop");
Console.WriteLine("Messages Count : " + iMsgs.Count.ToString());
// Get first message.
iEmbdded = iMsgs[1];
// Embed the message in oMsg by using BodyPart.
iDsrc = iEmbdded.DataSource;
iDsrc.SaveToObject(iBp, "IBodyPart");
// Send mail.
oMsg.Send();
iEmbdded = null;
oMsg = null;
iBp = null;
iMsgs = null;
iDropDir = null;
}
catch (Exception e)
{
Console.WriteLine("{0} Exception caught.", e);
}
return;
}
}
} - Press F5 to build and to run the program.

Community Feedback System
Very often, it takes hours to solve a problem. Very often, you've looked high
and low, and have tried a lot of solutions. When you finally found it, chances
are, it was because someone else helped you. Here's your chance to give back.
Use our community feedback tool to let others know what worked for you and what
didn't.
Please also understand that the community feedback system is not warranted to be
correct, it's simply a system that we've built to let people try and help each
other. If something in a feedback response doesn't make sense to you, or you're
not comfortable making changes that the feedback talks about (like registry
edits), please consult a professional.
