in EMA

I run the Example: Cpp-C/Ema/Examples/Training/Consumer/200_Series/270__SymbolList

Consumer.cpp:

try {
AppClient client;

OmmConsumer consumer( OmmConsumerConfig().host( "localhost:14002" ).username( "user1" ) );

UInt64 handle = consumer.registerClient( ReqMsg().domainType( MMT_SYMBOL_LIST ).serviceName( "ELEKTRON_DD" ).name( "0#/MBD.HK" ), client );

}
but I get the result :

Item Name: 0#/MBD.HK

Service Name: ELEKTRON_DD

Item State: Closed / Suspect / Not found / 'The record could not be found'

how can i the the result success,
what the Consumer.cpp should be.?

    tks Umer Nalla

    I am a new developer in china with EMA C++

    the article is very well，but developed in java，I even can not find the "FlatChain" in sdk（C++）;

    now my question is how can I get stock list conveniently with EMA (C++)

    Hi @luxiangyuan

    The techniques and mechanism described in the article for processing Chains is much the same in C++ and Java. So, you could refer to the articles and use the understanding to develop your own code to process chains in C++.

    EMA does not provide any built in classes for processing Chains specifically.

    hi Umer:

    but where can I find the implements of "

    import com.thomsonreuters.platformservices.elektron.objects.chain.Chain;

    import com.thomsonreuters.platformservices.elektron.objects.chain.FlatChain;"

    So I can refer to.

    thanks a lot

    As mentioned in the Chain articles, they can be found on github

    Hi,

    I can see you asked this question on a separate post and a colleague has answered. If that is not the same question - please explain further what usage you require.
