Can the emulator open a tcp socket to the host?

I am running VS2003. I have a C# console project that is accepting
socket connections. I have a C# console client that can connect to it (TCP,
port 1613).

However, when move the same code to a Compact Framework project (the client
that is, of course).
and try to use the emulator to connect to the accepting program, I get a
message about
the server actively rejecting the connection.

All IP addresses are hard coded:

public class StationMaster
{
string OrchHost = "192.168.1.50";
int OrchPort = 1613;
TcpClient OrchSock;
private NetworkStream OrchStream;
private StreamReader OrchRead;
private StreamWriter OrchWrite;
private AsyncCallback OrchCallback;
private byte[] IOBuffer;
private int IOBufferSize = 4096;
string PacketFile = "Packet.xml";
XmlDocument Xdoc = new XmlDocument();
StationMasterGUI TheGUI;

public StationMaster(StationMasterGUI gui)
{
OrchCallback = new AsyncCallback(this.onReadDone);
IOBuffer = new byte[IOBufferSize];
TheGUI = gui;
this.connect();
this.loadXml();
}
private void connect()
{
try
{
OrchSock = new TcpClient(OrchHost, OrchPort);
Tools.Debug(1, "Connected to: {0} on: {1}", OrchHost, OrchPort);
OrchStream = OrchSock.GetStream();
OrchRead = new StreamReader(OrchStream);
OrchWrite = new StreamWriter(OrchStream);
}
catch (Exception err)
{
Tools.Debug(10, "Connect to {0}:{1}:{2} failed" ,OrchHost, OrchPort,
err.ToString());
}
}

What happens if instead of
OrchSock = new TcpClient(OrchHost, OrchPort);
you try
OrchSock = new TcpClient(new IPEndPoint(IPAddress.Parse(OrchHost),
OrchPort));
?

Yea, I tried that one too. Same effect.

I've noticed you are using IP address "192.168.1.50". That would be the
virtual address of the PPP_PEER. Does the problem still occur when you use
the real IP address of your desktop?

Have you made sure to configure your emulator to access the Internet? Are
you able to browse to a web page using Pocket IE?

(I hope you don't mind me answering out of order)

2. With the Ipaq, I can use PIE to get to the internet, I can also use a
Flash App that I
created that opens up the TCP/IP socket of the thinkpad server app. The
problem is
restricted to trying to do the same think with the DotNet CF client app that
I want
to use to replace the Macromedia Flash communication portion.

BTW: The ipaq has pocket hosts, so I assume that is why I can easily see the
thinkpad.

1. Ahah! I had not seen anything about configuring the emulator. Can you
point
me to where I need to do this?

The configuration I have is simple. A linsys WiFi router. A thinkpad and an
Ipaq both
working in infrastructure mode and connected to the WiFi. PIE and IE apps
work from
both devices.

I am using static IP addresses (since sometimes I go out on the road and
need to use
ad-hoc mode). So the thinkpad has a fixed IP of 192.168.1.50 and the ipaq
192.168.1.60

Ipaq has pocket hosts and a translation for the thinkpads (chochma) name.

Besides, I have apps I wrote in Flash that open tcp/ip sockets to the
thinkpad. It is
only now when I am trying to move this to C# CF that I am having trouble. So
I expect
some sort of configuration problem is the heart of this.
