   Hi Karl,

   Thank you for a great API. I started using the IB JAVA API but as I know very little about JAVA had a tough time with it. Using your API, Visual Studio Express and C# I have made a lot of progress in a much shorter time even as a DOT NET newbie.

   To the point. I'm trying to match contract info between the client events and my application. I wanted the ContractId and wrote the following:
   
int EStickerId = 201;
string expiration = "200809"
ES = new Contract("ES", "GLOBEX", SecurityType.Future, "USD", expiration);
client.RequestMarketData(EStickerId, ES, null, false);
int EScontractId = ES.ContractId;

   expecting to get the ContractId in EScontractId but I get 0. I looked at the definition of Contract.ContractId and don't see it being set. I haven't checked (& don't really want to!) the JAVA API to see if that returns the right value. I have a workaround which gets the ContractId from the client_UpdatePortFolio event using e.Contract.ContractId but I have no guarantee that I will get client_UpdatePortFolio event ...

   Any help in getting the ContractId immediately after client.RequestMarketData would be much appreciated.

   I found a better workaround - using the symbol instead of the contract ID. It's not as robust but as I my ATS doesn't trade different expirations, that's not a problem :

   
int EStickerId = 201;
string expiration = "200809"
ES = new Contract("ES", "GLOBEX", SecurityType.Future, "USD", expiration);
client.RequestMarketData(EStickerId, ES, null, false);
string ESsymbol = ES.symbol;


   ES.symbol returns the correct data while ES.ContractId returns 0.<br>

   Once again, thanks again for an excellent API.

   Hey Ian,

   Use

   public void ReqContractDetails(
   Contract contract
   )

   The resulting call back will have the contractId set.
