Socket : UnAble To Communicate Through Internet?
Sep 26, 2009
I have started socket programming since last few days. I'm able to communicate when the server and client programs are run on the same computer (by specifying IP as 127.0.0.1) or on different computer which are on LAN(192.168.x.x .... etc.). But the problem is that i'm not able to communicate through internet when i provide Internet IP Address (assigned by my ISP) of computer on which server program is running.
Here's my code :
Server :
Imports System.Net.Sockets

Does anybody know what site has independant ASP.Net consultants that are for hire on an hourly rate and can communicate via the internet? I only need this consultant for a couple hours. I cannot recall the site that I used previously where I would ask questions for a price and get the solutions.

I have been struggling to find a solution for this problem. What I need to do is build a server application that accepts tcp client requests from different clients running on same port say:1003. I experimented by using asynchronous mode call backs etc. but it disconnects once connection is established and does not respond for further requests from the same client.

i have made a console based socket program in vb.net, all it does 2 things:
1- server shows a msgbox when the command msg is sent from the client
2- the server opens the cd try when the command open is sent form the client
when i run it , i type the command open and works just fine , the cd tray opens , but if i type open again or msg it simply wont do anything(this also applies for the command msg, if type it a msg is shown, but if i type it agine or open , it wont respond. so its like one command per session.i tried to put the code in a while loop , but didnt work
here is the code for the server:
Imports System.IO
Imports System.Net.Sockets
Module Module1

I wrote a Socket Client which will send the Socket Server some data and get some response from Server. This process will be running once in every 2 seconds.
Now what I need to know is How we can identify the connection lost between Server and Client?
I need this to be implemented in the Client side. If there is no connection then Client should automatically close the connection. Once the connection with the server is available in the next attempt it should connect automatically.

we have our system running but our system needs to be modified because we did something wrong...we are doing an "Internet monitoring System" in our school library where the user can only access the internet 1hr a day, and he/she cannot use the internet within that day if he couldn't buy a time on a serve...every students should only have 20hrs time usage per semester...our problem is every day their 20hrs is being reduced in 1hr.. the rule is the time per semester which is 20hrs that is given to the students was reduced 1hr only if he uses the internet..but our system is reducing their 1hr every day.

I wish to communicate over usb in vb.net i realize i might need to use openfile windows api or createfile windows api but im doing a generic mouse driver which should be miles simpler to do since microsoft and usb.org already have the report descriptors available so all i want to do is just send data to the device directly using my program.

I'm working on a little app which needs to recieve information from a script on a web server. I tried to have the vb.net app pole a php web page for a command every half of a second. This worked but, the app is streaming video and every time the app needs to pole the webpage the video stutter stops. I tried setting the pole timer to 5 seconds and still every 5 seconds the video stutters. I thought that maybe sockets would be the answer, so I looked for examples of vb.net socket servers and php socket clients. I tried implementing a solution but the php cannot seem to connect to the vb.net server. I googled around and saw that maybe php cannot communicate with a vb.net application.

I am trying to send and receive packets over the LAN (i.e. NIC port) using VB.NET. I found some code that uses Socket wrench, but problem with such solutions is that users will need to install extra drivers and all which I do not want. I am looking to use drivers native to the .NET environment to send and receive packets through the LAN port. My windows forms application is in VB.NETneil

I have a library that interacts with our phone system, ie, Hey phone, call this number for me. This library is used in one of our in house products. I would like to put this instead in a service, so that any of our in house products can send the service a message to place a phone call. So basically I want to communicate from a program built in .Net 3.5 with a service running on the same machine also built in the 3.5 framework. I have done some work with WCF and was considering using this but thought I would ask what others have done or would do.

I'm coding a restaurant program where every table, server and guest is a different object - Is there a right way of getting objects to communicate with each other?For example, one server might have 5 table objects, each table might have 2 guest objects. Is there a way to neatly tie all this information together. If a guest moves to a different table I have to change a large number of variables (number of guests served by server, table set to empty, new table sat...etc etc.)?
