socket problem

[n30 [Dzej O.]]

Hi
I ve got small problem with the "connect"
I made a application waiting for a connection and for a data.
And I written in VS 2005 ap rogram w pocket pc.
Program is working good on the Pc. The problem is that is crashing down
on the pocket.
I tried to use 2 difrent ways to connect:

TcpClient klient = new TcpClient();
klient.Connect(IPAddress.Parse("192.168.1.19"),
int.Parse("6667"));
NetworkStream stream = klient.GetStream();
BinaryWriter w = new BinaryWriter(stream);
w.Write("MSG!");

********************************************************
And:

********************************************************
Socket s = null;
IPEndPoint ipe = new
IPEndPoint(IPAddress.Parse("192.168.1.19"), int.Parse("6667"));
Socket tempSocket = new Socket(ipe.AddressFamily,
SocketType.Stream, ProtocolType.Tcp);

tempSocket.Connect(ipe);

if (tempSocket.Connected)
{
s = tempSocket;
}

string Data_to_send = "MSG!!";
Byte[] bytesSent = Encoding.ASCII.GetBytes(Data_to_send);
s.Send(bytesSent, bytesSent.Length, 0);

*************************************************************
in details after crash on pocket pc in first lines i see problem with
the connect method. Can someone help me?


regards!

What exception are you getting if you are getting an exception.

In translation from my native:

Error msg cannot be displayed becouse there is no resources with that msg.


in:
Syste.net.socket.nocheck()

in:
Syste.net.socket.connect()


....

in DeviceApplication1.Program.Main()

....


I belive that problem is in compact framework on the pocket pc.
tha package propably do not have the connect method.
B ut this theory is failing when i delete the code from line with
connect method.
So class Socket is impleted to the CF, and I don't beleive that someone
putted Socket class without connect method...

connect is definitely implemented in Socket. You need to determine the type
of the exception that occurs, the fact that there isn't a message isn't the
root issue. Can you check (e.g. with Internet Explorer Mobile) that you have
network connectivity and that you can reach this particular host, also make
sure you don't have any firewalls etc in between. If you are testing this
through an ActiveSync passthrough connection you'll probably find this is
not letting traffic through on that port, you should try on a direct e.g.
WiFi network.

Try installing the System_SR cab file (if using CF 2.0 or <) so you can see
the exception.
