  I can read a 32 bit counter value by using the code below.
    snmp_mng->QuickSend("1.3.6.1.2.1.2.2.1.10.4","public","192.168.2.1",1);
     inoctet = StrToInt(snmp_mng->Reply->Value[0]);

  But I can't get the counter64 type value by using the code below? Is there 
a special way of reading it?
    snmp_mng->QuickSend("1.3.6.1.3.9999.1.2.1.3.5","public",pch_snmp,1);
    total_inoctet = snmp_mng->Reply->Value[0];

I captured the traffic. The response for my request for this OID is coming 
to my computer. Also other SNMP manager utilities can read the value of this 
OID but by using Indy 9, I couldn't read it.

Please be more specific.  What does the data actualy look like?  Have you
tried StrToInt64()?

Why not?  You need to be more specific.

The data returned is NULL for value[0]. I tried to use strtoint64() now but 
I didn't work. As you can see in my first message, the only change in my 
code is the OID that I requested. I also checked the ValueType of OID for 
the reply and it is true(70) but the value[0] is NULL.

Indy doesn't have any knowledge of that particular ValueType, so it doesn't
know how to decode it when filling in the Reply values.  The value is NULL
since it is an unknown type.  This is because Counter64 was added in SNMP
v2, which Indy does not implement yet.

Thank you for your answer. I wonder if it is impossible to read the response 
by using udpbase->responsestring() function. Or is there any other way to 
get the value of this counter64?

An easier way would be to manually update IdASN1Utils.pas to recognize
Counter64 types, and then recompile the Indy library.  That way, you can
continue using TIdSNMP as-is, and you should then have non-NUL string values
that you can pass to StrToInt64()..
