[AGENT++]how to send a trap?

[Jerry OELoo]

hi all
   I have sent a notification with code as shown below:
coldStartOid coldOid;

NotificationOriginator no;

UdpAddress dest("127.0.0.1/162");

no.add_v1_trap_destination(dest);

no.generate(vbs, 0, coldOid, "", "");

but when i run the program,it crashes and shows :0xC0000005: Access 
Violation.
I want to know why?  and I have found something in the maillist:
Frank Fock recommend to use theMib::notify method.
but as this method ,how do I configure the manager' address and port ?
Thanks in advance!

Jerry
