Trap SNMP

[saraf]

Hi,
I want to send trap to my snmp program.
I have find this code in internet that send a trap, but it doesn't run correctly bacause my SNMP don't catch any trap!!!

#include "stdafx.h" 

#using <mscorlib.dll> 
#include <Winsnmp.h> 
#include <windows.h> 

using namespace System; 

SNMPAPI_STATUS CALLBACK cbFunc 
(HSNMP_SESSION hSession, HWND hWnd, UINT wMsg, 
WPARAM wParam, LPARAM lParam, LPVOID lpClientData) 
{ // This is a noop function for this app, but must be present. 
return (SNMPAPI_SUCCESS); 
} 


int _tmain(){ 

DWORD nTime1=0, nTime2=0; 
HSNMP_SESSION hSession; 
HSNMP_ENTITY hDst; 
HSNMP_CONTEXT hContext; 
HSNMP_VBL hVbl; 
HSNMP_PDU hPdu; 
SNMPAPI_CALLBACK cB = &cbFunc; 
smiOCTETS dContext = {6, (unsigned char *)"CIAOOO"}; 

smiUINT32 lStat; 
smiUINT32 sysUpTime[] = {1,3,6,1,2,1,1,3,0}; 
smiUINT32 snmpTrapOid[] = {1,3,6,1,6,3,1 ,1,4,1,0}; 
smiUINT32 trapValue[] = {1,3,6,1,4,1,12,1,1,1,210}; 

smiOID dSysUpTimeName = {9, sysUpTime}; 
smiOID dTrapName = {11, snmpTrapOid}; 
smiOID dTrapName2 = {11, trapValue}; 

smiVALUE valSysUpTime; 
smiVALUE valTrap; 
smiVALUE valTrap2; 

lStat = SnmpStartup (&lStat, &lStat, &lStat, &lStat, &lStat); 
if (lStat == SNMPAPI_FAILURE) 
return (0); // exit 
lStat = SnmpSetRetransmitMode(SNMPAPI_ON); 
hSession = SnmpCreateSession(NULL, 0, cB, NULL); 

if (hSession == SNMPAPI_FAILURE) 
{ 
printf ("SnmpCreateSession() failed!\n"); 
lStat = SnmpClose (hSession); 
lStat = SnmpCleanup (); 
return (0); 
} 

lStat = SnmpSetTranslateMode (SNMPAPI_TRANSLATED); //SNMPAPI_UNTRANSLATED_V1 

//THIS IS THE IPADRESS OF SERVER WHERE IS INSTALLER SNMP PROGRAM
hDst = SnmpStrToEntity (hSession, "192.168.1.10"); 
lStat = SnmpSetPort (hDst, 162); 

hContext = SnmpStrToContext(hSession, &dContext); 
hVbl = SnmpCreateVbl (hSession, NULL, NULL); 

valSysUpTime.syntax = SNMP_SYNTAX_TIMETICKS; 
valSysUpTime.value.uNumber = GetTickCount() / 10; 
lStat = SnmpSetVb (hVbl, 0, &dSysUpTimeName, &valSysUpTime); 

valTrap.syntax = SNMP_SYNTAX_OID; 
valTrap.value.oid.len = 11; 
valTrap.value.oid.ptr = trapValue; 
lStat = SnmpSetVb (hVbl, 0, &dTrapName, &valTrap); 

valTrap2.syntax = SNMP_SYNTAX_INT; 
valTrap2.value.sNumber = 210; 
lStat = SnmpSetVb (hVbl, 0, &dTrapName2, &valTrap2); 

hPdu = SnmpCreatePdu (hSession, SNMP_PDU_TRAP, 1, 0, 0, hVbl); 

nTime1 = GetTickCount(); 
lStat = SnmpSendMsg (hSession, NULL, hDst, hContext, hPdu); 
if (lStat != SNMPAPI_SUCCESS) 
{ 
printf ("SnmpSendMsg() failed:\n" ); 
} 

nTime2 = GetTickCount(); 
printf ("Elapsed time (in milliseconds): %u \n", nTime2 - nTime1); 
lStat = SnmpFreeContext(hContext); 
lStat = SnmpClose (hSession); 
lStat = SnmpCleanup (); 

return (0); 

}

Why my SNMP don't catch trap send by this code??
It's possibile to set priprity of trap??
Where I set the string message of trap??
I hope in you help!!
Thanks

Bye
