Hello, I found following: DTC server return me Logon Response with size = 256. (Fixed binary enc., logon success.) In the same time when we sum all data lenghts from s_LogonResponse structure (DTCProtocol.h) then get 262 bytes. How is it possible? NB: string ServerName is converted from response's byte[] successfully to "SC DTC Server", but string SymbolExchangeDelimiter - is not - it has value "\u0001\0\0\u0001". Is the length of ServerName in the file DTCProtocol.h specified correctly? Correct me if I am wrong... Thank you. struct s_LogonResponse { uint16_t Size; uint16_t Type; int32_t ProtocolVersion; LogonStatusEnum Result; char ResultText[TEXT_DESCRIPTION_LENGTH]; //96 char ReconnectAddress[64]; int32_t Integer_1; char ServerName[60]; uint8_t MarketDepthUpdatesBestBidAndAsk; uint8_t TradingIsSupported; uint8_t OCOOrdersSupported; uint8_t OrderCancelReplaceSupported; char SymbolExchangeDelimiter[SYMBOL_EXCHANGE_DELIMITER_LENGTH]; //4 uint8_t SecurityDefinitionsSupported; uint8_t HistoricalPriceDataSupported; uint8_t ResubscribeWhenMarketDataFeedAvailable; uint8_t MarketDepthIsSupported; uint8_t OneHistoricalPriceDataRequestPerConnection; uint8_t BracketOrdersSupported; uint8_t UseIntegerPriceOrderMessages; uint8_t UsesMultiplePositionsPerSymbolAndTradeAccount; uint8_t MarketDataSupported; |

With #pragma pack(8), the compiler reports the size as: DTC::s_LogonResponse size: 256 Here is the current header file: http://dtcprotocol.org/DTC_Files/DTCProtocol.h We cannot say anything further on this. Date Time Of Last Edit: 2017-12-23 22:45:05
