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:
| 1. | Start Microsoft Visual Studio .NET or Microsoft Visual Studio 2005. |
| 2. | On the File menu, click New, and then click Project. |
| 3. | 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. |
| 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, locate Microsoft CDO For Windows 2000 Library, and then click Select.
Note In Microsoft Visual C# 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 select, 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.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;
}
}
} |
| 6. | Press F5 to build and to run the program. |
