I am going to create a gaming platform primarily with flash,flex and was also looking to create a windows client that could communicate with my server using these protocols. Could someone point me in the right direction on any possible .net libraries available that could handle the communications between client and server?

I want to make two PCs communicate via network using server/client I followed the example from this site: [URL] (VB.NET TCP Client/Server Socket Commmunications) When I run the applications server and client in one computer then is possible the client to connect with server.

basically i just want client to say "C: emp" ENTER
then, server must reply with all its files in c: emp
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.
View 1 Replieshow to create a client/server... But I couldn't... I don't want anything fancy. Just want the client to send the server 4 numbers, depending on the user's choice; after that, the server would turn off the pc, restart it, etc. It all depends on the number received. Is there a rather "simple" way to do it? If it's not to much trouble you could use Atheist's example. (Btw I don't understand the code and, yes, I've checked on [URL])
View 9 RepliesHowever I have hit a massive brick wall with my program. My program that I'm trying (can't emphasis this word the importance of that word) to create a Client/Server chatroom using TCPClient in Visual Basic. So far I can get my client to speak to my server. However, i'm trying to get the returned data to display in a listbox which never happened, i then tried a label, which again never happened then a text box which I'm sure you can figure out how that went! I'm not great at networking programmers nor am I not bad I'm terrible but duty calls when it comes to projects.
The code I currently have was mostly taken from the net but when I have the program fully work and I understand how the software works I intend to heavily modify for it to suit the needs of what I need to achieve. where I can get my client to display the data from the server that I have already sent to the server (which displays successfully within the server).
[Code].....
Im using the code from [URL] as a starter, most of the code is the same. the chat system works fine but on the client a added a disconnect button "clientSocket.Close()" and as soon as i click that i get errors, on the client, this is the code...
Private Sub getMessage()
For infiniteCounter = 1 To 2
[CODE]...
And this line...
serverStream.Read(inStream, 0, buffSize)
gives me "Unable to read data from the transport connection: A blocking operation was interrupted by a call to WSACancelBlockingCall."
Now im talking the server, after the client clicks disconnect or closes by task manager, looses connection, etc the server crashes and gives me.
I have developed 2-3 standalone windows application using VS2008(vb.net) + Sql server (2008,2005) and quite comfortable with stand alone windows application. Now i am trying to make a windows app which will share a server database on LAN. I googled alot about this but still no success. So i decided to make that as stand alone app and i just changes the connection string to use remote server database. Everything is working fine still. All the insert, update and delete query are same as stand alone n me not getting any problem while testing through one more remote client system. But while googling i heard abt "CONCURRENCY" control.So please guide me is anything wll b wrong in future wid my this application when i will deploy this to my users? What about locks and how can i implement this to my Insert, update and delete queries to control concurrency and maintain integrity ?Please guide me step by step becoz i m new be to client/server application.

View 1 RepliesI am trying to create a server/client program in vb.net. What I am trying to do is test a battery that is running on a handheld (which runs Windows CE 5) by connecting to a "server" and sending information every 10 seconds or so. I am very new to .NET, and am not really sure how to go about doing this. I want two separate applications running, with the server-side keeping all of the data, since the battery is going to die, and I will lose any information if I keep it client-side. I am also new to networking, so I was not sure of whether I should create a Socket, or if I should try to do something else.

View 10 RepliesWe would like to create a client-server architecture application that the server can control all client computers connected to it (e.g shutdown) and we would like to put a security login and a desktop lockeron the clients. The process of the system is that when the clients starts, the desktop is locked and ofcourse the user can't access the desktop unless he/she logged-in. And when the scheduled time (e.g 1 hour) is done, the client computers where automatically shutdown like the Time Logger Softwares

I am writing a Windows form application where a client has the ability to add as many chart as needed in the form by clicking at an icon in the menu bar at run time. These charts will have the same format, and I will have them linked to a text box for the client to select which entity to chart.I have no clue where to start. I did a web search and I have found articles that show how to add user's control at design time (I don't think it is what I want).
