Hello forum members,
I have a problem receiving fix server indication when sending logon fix
message
I was creatig a c# console app program using async request to a fix demo
gateway
using this code:
using System;
using System.Text;
using System.IO;
using System.Net;
using System.Net.Sockets;
using System.Security.Cryptography;
using System.Threading;
namespace Simple_async_socket_coonnect
{
public static class GlobalVar
{
static Byte[] _globalValueByteGetreceive;
/// <summary>
/// Access routine for global variable.
/// </summary>
public static Byte[] GlobalValueByteGetreceive
{
get
{
return _globalValueByteGetreceive;
}
set
{
_globalValueByteGetreceive = value;
}
}
/// <summary>
/// Static value protected by access routine.
/// </summary>
static Byte[] _globalValueByteGet;
/// <summary>
/// Access routine for global variable.
/// </summary>
public static Byte[] GlobalValueByteGet
{
get
{
return _globalValueByteGet;
}
set
{
_globalValueByteGet = value;
}
}
/// <summary>
/// Global static field.
/// </summary>
public static bool GlobalBoolean;
}
class Program
{
static void Main(string[] args)
{
Console.WriteLine(DoSocketGet("*****"));
}
static string DoSocketGet(string server)
{
//Set up variables and String to write to the server.
Random random = new Random();
Encoding ASCII = Encoding.ASCII;
StringBuilder nt = new StringBuilder();
nt.Append("8=FIX.4.4/9=136/35=A/49=*****/56=***/34=596");
//nt.Append("34=" + random.Next(1000) + " 52=" +
DateTime.UtcNow.ToString("yyyyMMdd-HH:mm:ss") + " 98=0 108=30 554=" +
sha256encrypt("1bird2lake") + " 10=015");
nt.Append("/52=" + DateTime.UtcNow.ToString("yyyyMMdd-HH:mm:ss") +
"/98=0/108=30" + "/554=" + sha256encrypt("*****") + "/10=118/");
string Get = nt.ToString();
Byte[] ByteGet = ASCII.GetBytes(Get);
GlobalVar.GlobalValueByteGet = ByteGet;
Byte[] RecvBytes = new Byte[256];
GlobalVar.GlobalValueByteGetreceive = RecvBytes;
String strRetPage = null;

IPEndPoint hostEndPoint;

ProtocolType.Tcp);
// Connect to the host using its IPEndPoint.
// ManualResetEvent connectDone = new ManualResetEvent(false);
s.BeginConnect(hostEndPoint, new AsyncCallback(Connected),
s);///async connection request request
// connectDone.WaitOne(1000,false);
return strRetPage;
}
public static void Connected(IAsyncResult iar)
{
Socket sock = (Socket)iar.AsyncState;
try
{
sock.EndConnect(iar);
sock.BeginSend(GlobalVar.GlobalValueByteGet, 0,
GlobalVar.GlobalValueByteGet.Length, SocketFlags.None, new
AsyncCallback(SendData), sock);
}
catch (SocketException)
{
Console.WriteLine("Unable to connect to host");
}
}
static void ReceivedData(IAsyncResult iar)
{
//I dont get a response from the server here i dont stop here at
break point
//its eather my code is wring or the fix message is wrong
Socket remote = (Socket)iar.AsyncState;
int recv = remote.EndReceive(iar);
string receivedData =
Encoding.ASCII.GetString(GlobalVar.GlobalValueByteGetreceive, 0, recv);
Console.WriteLine(receivedData);

public static string sha256encrypt(string phrase)

StringBuilder output = new StringBuilder("");
for (int i = 0; i < inputArray.Length; i++)
{
output.Append(inputArray[i].ToString("X2"));
}
return output.ToString();
}
}
}
I am sending this string as my login message
8=FIX.4.4/9=136/35=A/49=****/56=MBT/34=1/52=20091230-18:41:27/98=0/108=30/554=AD8C8A0692F9B051E0A6CA3ED6123F7430C3CBF08E3ABF15E54F47D92E93C3C7/10=118/
and don't get any response which means i am not getting into ReceivedData
function
I am stuck at this point and I wil be glad to get some direction what is the
problem
(might be my c# code or my fix string)
best regards
eyal
