View 3 RepliesPass Messages To Clients?
Feb 4, 2011I'm developing an application, which will have a common db in a server (SQLServer db) and the client PCs will have my program installed - in a LAN.
So, my question is, when the users in the client PC wants to pass some messages (for eg: one of the user got a message from his boss that all of them are requested to meet him). That is, I want to implement a communication system through my app. It will be a common message system. That is, just like a shoutbox.
So, do I have to use a TCP based communication system or just use a timer to check the db for any new messages and display them ?

View 1 RepliesThreading Clients Using A Tcp Listener?
Dec 2, 2009(Using vb 2008 express.)
I am trying to create a server to send clients text on request. I am using a tcp listener to accept clients then send each client to a thread in a threadpool which deals with each client's request then closes the client connection. It seems to work fine but I would like to know how it works. Using the listen loop below I cant help feeling I should be sending some values to the threaded sub. How does it know which client each thread is dealing with?

VS 2008 Instances With Tcp Clients
Oct 4, 2009I am programming a chat like application using Tcp. Now I have a probem. I am going to have loads and loads of data being transferred so I will have to use 4 seperate ports.[code...]
My problem is for me to use a maximum of 4 ports all together transferring data from the client(s) to the server(s) I will need 4 clients and 4 servers. I need to open 4 instances of 4 clients. I was going to put a client in a form and then when the client is running it creates 4 instances of that form but than there would be too much confusion going on. I think there my be a way to use Classes instead of forms.

View 4 RepliesClients Stop Receiving Data Suddenly
Jan 23, 2009I am working on a client/server application. Everything seems to go well for a while (a few hrs, a few mins its kind of random) then suddenly clients stop receiving data. maybe 1 or two, or all of them. in the end I end up having to restart the server piece to resolve it, but I am trying to understand why its doing this. I've added try catches around the send piece, but it doesnt error out. When the app fires, the listener is started on its own thread. When a new connection is made, that connection is passed to a class that handles all of my connection data(send/receive, responding to commands, etc). The class is started in its own thread, so each connection is running in its own memory space. This issue seems to happen with 1 client connected, or 20, it doesn't really seem to matter.
This causes other issues, like a customer who thinks he is disconnected, will shut down his app, which is supposed to send a command to close the connection on the server side which it does not., so now I have several "closed" connections still open on the server, which is obviously also bad. Another thing I dont get is that it worked fine when I was developing the pieces on my dev box, so I dont get why I have all of these "timeout" issues now. (I put that in quotes, because the timeout period is the default of 10 mins, and I xmit data, at LEAST every minute when the server pushes data updates to all clients)
Here is some of the relevant code
vb
'Command Object, this holds all of the command information being passed back and forth to tell the server what to do, and as well as hold the response.
'The strCMD is the command, strParms is the parameters of the command, obj is ANY object I want to send along with this information

The problem i am having is that it will not run on a machine that doesnt seem to have the correct drivers that its looking for. When i install ODAC 11.2 Release 3 (11.2.0.2.1) with Oracle Developer Tools for Visual Studio on the test VM it works just fine but thats a 230+mb file to download and install! Not to mention that if the user already has Oracle 10/11g on their machine that it may mess up their current connections/etc by installing that setup file.Is there another setup package that i can install that only has the Oracle Data Provider for .NET 2.0 11.2.0.2.0 or whatever its needing from that ODAC 11.2 Release 3 file.
