Please help me understand why this TCP client & server wont connect.

[Stigern]

Just made this simple TCP client and server with help from a tutorial. Only problem I'm facing now is!

It can't connect over lan or internet, works perfect hosting a localhost server and connecting to it. It's weird.

It's programmed in Visual basic 2005 express.

Projectfiles:

Please help me, It's so annoying getting stuck with such a error as this ><

Just out of curiosity, can you confirm that you don't have a firewall blocking the port you are using?

could you post the code for your connecting and accpeting of connection?

[Stigern]

Firewall is off yes. Both on router and windows.

qazwsx: look in the projectfiles. Code is there

Where you catch an exception on connect have you displayed the actual message being generated? That may geive you a idea of the reason the connect is failing.

Hi
I don't have any solution for you, but when I run the app. connection seams to be ok. I can't send message to the server or vice versa. When checking for errors it seams to be something with the StreamReceiver AsyncResult.

In your code you have many "Try .. Catch" blocks of code. If the "Catch" code gets executed - ie there is an error of some sort - the Exception Object will contain details about the error. All I was asking, was whether you'd looked at the Message in the Exception Object to see why the Connection failed.
(I'm not a .NETter so the terminology might not be correct but the principle is. You've gone to all that trouble to detect when an error is generated and then not reported why it happened)
