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!
Ps. Sorry for language mistakes, EN is not my native.

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...

Regards.

Ps. Sorry for Language mistakes.

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

Thx your advice solved problem out!
I used the connecion form active sync.
