I don't know for sure, but I'd try putting a Guid attribute on the class
like:
[Guid("00000000-0000-0000-0000-000000000000")]
public class SmtpWatcher : CDO.ISMTPOnArrival {
and after registering the assembly, putting it into the GAC like
gacutil /i SMTPWatcherLib.dll
which will allow it to be found regardless of the directory of the calling
application.
Also, I'm assuming the typo of SMTP in the following:
> I tried using cscript smtpreg.vbs /add 1 onarrival MySink
> STMPWatcherLib.SmtpWatcher "mail from=*",
is in the e-mail only, not what you were actually trying.
HTH,
Jim

Subject: [ADVANCED-DOTNET] Handling SMTPOnArrival COM events
We are trying to watch an Exchange Server for new messages and extract
attachments arriving. I looked at the documentation for CDO, and found
the ISMTPOnArrival interface. Following the guidelines in the .NET SDK
for advance COM Interop, I used tlbimp to create a wrapper for CDO.
What I came up with was the following code:
using System;
using System.IO;
using System.Runtime.InteropServices;
using CDO;
using ADODB;
namespace SMTPWatcherLib {
/// <summary>
/// Summary description for Class1.
/// </summary>
public class SmtpWatcher : CDO.ISMTPOnArrival {
static private CDO.SMTPConnectorClass smtpCon = null;
public SmtpWatcher() {
}
public static void Main() {
SmtpWatcher smtpWatcher = new SmtpWatcher();
smtpWatcher.Run();
Console.Read();
}
public void Run() {
smtpCon = new SMTPConnectorClass();
CDO.ISMTPOnArrival_OnArrivalEventHandler
SMTPMessageArrived = new
CDO.ISMTPOnArrival_OnArrivalEventHandler(OnArrival);
smtpCon.OnArrival += SMTPMessageArrived;
}
public void OnArrival(CDO.Message Msg, ref
CDO.CdoEventStatus EventStatus) {
IBodyParts parts = Msg.Attachments;
FileStream logStream =
File.Create(@"C:\test\OnArrivalLog.txt");
StreamWriter writer = new
StreamWriter(logStream);
try {
writer.WriteLine("From: " + Msg.From);
writer.WriteLine("Subject: " +
Msg.Subject);
foreach(IBodyPart part in parts) {
part.SaveToFile(part.FileName);
}
EventStatus =
CdoEventStatus.cdoRunNextSink;
}
catch {
}
finally {
logStream.Flush();
writer.Flush();
logStream.Close();
writer.Close();
}
}
}
}
I used RegAsm to register the assembly, but what now? It's not doing a
thing. I tried using cscript smtpreg.vbs /add 1 onarrival MySink
STMPWatcherLib.SmtpWatcher "mail from=*", and it appears to register the
bindings, but nothing happens.
I also tried making this just a class library, but no effect. I don't
know much about COM, so please help me out here.
Thanks a lot,
Richard A. Hein
