.NET Forum / .NET Framework / Interop / December 2004Send out email using CDO
Hi, I tried to send out email using CDO: 1. Add reference: Microsoft CDO for Exchange 2000 2. Dim objSession As Object objSession = CreateObject("MAPI.session") But I got error: Cannot create ActiveX component (point to above line) Could you help me with it? Thanks in advance. Li Hi Have you tried to add a COM reference to the Microsoft CDO for exchange 2000 library by right click on the reference and select add reference. In the forwarding dialog, select COM tab and select the Microsoft CDO for exchange 2000 library. If you can not find that library, it may be caused by that you have not installed the library. Usually, the library is installed with exchange server, after installation, you will find cdoex.dll in the location below. C:\Program Files\Common Files\Microsoft Shared\CDO\CDOEX.DLL Hope this helps.

Hi, Try to see the following link: http://support.microsoft.com/default.aspx?scid=kb;en-us;327219 Btw, why don't you try System.Web.Mail? It is much simpler, I think. wl@newsgroup.nospam> wrote in message news:4E64C26E-E5B7-4E7D-B0A9-9DA53867F897@microsoft.com... > Hi, > [quoted text clipped - 11 lines] > > Li Thanks, Peter and Igor. I need to retrieve email, Web.Mail doesn't support. I guess the problem is I didn't run program on Exchange server. I plan to use WebDAV instead.

Hi Guys - My problem is closely related to this thread - CDO and the System.Web.Mail .NET object. My simple 10-line test program works fine on WinXP and Server2000, but fails on Server2003 (all boxes on the same network, all can ping the mail server). The error is: System.Web.HttpException: Could not access 'CDO.Message' object. ---> System.Reflection.TargetInvocationException: Excep tion has been thrown by the target of an invocation. ---> System.Runtime.InteropServices.COMException (0x80040213): The transport failed to connect to the server. The Server2003 box has CDOSYS.dll but not CDOEX.dll; according to the PRB link previously mentioned in this thread that's OK, since the Server2003 box does not run Exchange. Any ideas? Anything else 'special' about Server2003 and CDO? Thanks!
