minimum implementation for smtp-set

["Nölle, Jochen"]

Hello,

could someone tell me what code implementation has to be done to set a
variable from a management system in an agent++ application?
I tried to implement a small piece of code using MS Visual C++6.0.
Snmp-get works but if a set-pdu has been received the application
crashes in 
function "void MibLeaf::replace_value(SnmpSyntax* v)" in the
delete-function. VC++ says "HEAP[AgentppTest.exe]: Invalid Address
specified to RtlValidateHeap( 310000, 89a980 )".

Previously I compiled a mib-class "my_test_mib" with the agentgen-tool
containing an octet-string and an integer value.

This is the code:
--------------------
 Mib mib;
 int status;
 Snmpx snmp(status, 163);

 if(status !=SNMP_CLASS_SUCCESS)
 {
	return FALSE;
 }
 RequestList ReqList;

 mib.set_request_list(&ReqList);
 mib.add(new my_test_mib); 
 ReqList.set_snmp(&snmp);
	for(;;)
	{
		req = ReqList.receive(30);

		if(req)
			mib.process_request(req);
	}
	return TRUE;  // return TRUE  unless you set the focus to a
control
--------------------

In my opinion, it is hard work for a newcomer, who just makes first
steps working with snmp trying to make agent++ work because of missing
introduction to the package. The example code comes with no explanation
about its functionality. 

Could someone give me some help?

Thanks,
