Socket could not connect with c# server

[muaz111111]

Huy,

i have to transfer text b/w symbian application and server application written in c#. The socket initilization and connection codes are as follow,

For C#:

Socket mySocket = new Socket(AddressFamily.InterNetwork, SocketType.Stream,ProtocolType.Tcp);

IPEndPoint ipep = new IPEndPoint(IPAddress.Parse("127.0.0.1"), Convert.ToInt32(15000));
mySocket.Bind(ipep);
mySocket.Listen(10);




For Symbian Application:

void CSocketsEngine::ConstructL()
{
ChangeStatus(ENotConnected);

// Start a timer
iTimer = CTimeOutTimer::NewL(EPriorityHigh, *this);
CActiveScheduler::Add(this);

// Open channel to Socket Server
User::LeaveIfError(iSocketServ.Connect());

// Create socket read and write active objects
iSocketsReader = CSocketsReader::NewL(*this, iSocket);
iSocketsWriter = CSocketsWriter::NewL(*this, iSocket);
}

void CSocketsEngine::ConnectL()
{
// Initiate connection process
if (iEngineStatus == ENotConnected)
{
TInetAddr addr;
if (addr.Input("127.0.0.1") == KErrNone)
{
// server name is already a valid ip address
ConnectL(addr.Address());
}
else // need to look up name using dns
{
// Initiate DNS
User::LeaveIfError(iResolver.Open(iSocketServ, KAfInet, KProtocolInetUdp));
// DNS request for name resolution
iResolver.GetByName(iServerName, iNameEntry, iStatus);

ChangeStatus(ELookingUp);
// Request time out
iTimer->After(KTimeOut);
SetActive();
}
}
}

void CSocketsEngine::ConnectL(TUint32 aAddr) // <a name="ConnectL32">
{
// Initiate attempt to connect to a socket by IP address
if (iEngineStatus == ENotConnected)
{
// Open a TCP socket
User::LeaveIfError(iSocket.Open(iSocketServ, KAfInet, KSockStream, KProtocolInetTcp));

// Set up address information
iAddress.SetPort(15000);
iAddress.SetAddress(aAddr);

// Initiate socket connection
iSocket.Connect(iAddress, iStatus);
ChangeStatus(EConnecting);

// Start a timeout
iTimer->After(KTimeOut);

SetActive();
}
}


Plz suggest me what would be the problem. I would be very thankful to all prople.

Generally your code seems to be OK. However you have probably modified some details (I doubt that the addr.Input("127.0.0.1") expression would compile), so the IP address itself might be a problem, especially if the Symbian code runs on the target device (but it should work in the emulator I think).
You can test the server code using Telnet on your PC. For example I am not sure if the lack of something like mySocket.Accept is a copy-paste problem, or it does not exist at all.
