create a chat room? My current hosting is a linux server with mysql. I want to make a client that can connect to the database.(already done) and if the user exists, to open a chat form. I want this to be multithreaded, that way I can have up to 500 people chatting with each other at the same time, from different locations. (realistically will usually be around 50)I have found some winsock type examples, but I dont understand how I can adapt that to work with a linux server... Can anyone help give me examples? I guess I basically want an IRC.(Which I dont know how to implement.)

View 1 RepliesIs there any way to build a web based chat room application by using VB.NET as behind code and put it with ASP.NET on the web so users can login the account and start to chat without keep refreshing the browser or frame and have a real time transaction, I know that I have to use .NET.Socket namespaces, but don't know exactly how. I have seen many examples of windows based applications, but I need to know how to put it on the web.

View 1 RepliesHow would I create a multi-tcp chat room. Im having trouble handling them. I know you can store the connections as arrays or store then in hash tables. Is there a better way to data to a specific connected client. My way was to just broadcast the message to all the connected with the clients name (EX: Client1||MessageHere) || is the split. The client reads the message and sees if client name matches if it does then it will display it other then that it will not. I found out that my server was sending out useless data with this method. So is there a better way to handle/Send messages to a specific client?
View 2 Repliesfor few solutions it work outs well but not for the following code. I find an error when executing the following code. I find an error :

The compiler is telling me that these signatures are incompatiable, but they seem fine to me.[code].....

I have a section of code that deletes a lot of columns, one at at time, based on conditions that arise. Currently it does this:
objrpt.objXLSheet.Columns(col) _
.EntireColumn.Delete(Excel.XlDeleteShiftDirection.xlShiftToLeft)
There are so many of these, that I'm getting tired of looking at these lines so I want to curry the references to the Excel stuff.I tried:
Dim DelCol As Func(Of Integer) = Function(col As Integer) _
objrpt.objXLSheet.Columns(col) _
.EntireColumn.Delete(Excel.XlDeleteShiftDirection.xlShiftToLeft)
but that won't compile, giving me the error: "Nested function does not have the same signature as delegate 'System.Func(Of Integer)'. Ah forget it. I see that I'm trying to call a method from a function. I guess that won't work.Wait, I'm now trying it another way. I first defined a function:
Private Function DeleteColumn(ByRef objrpt As ExcelReport, ByVal col As Integer) As Object
DeleteColumn = Nothing
Dim objrng As Excel.Range
[code]....
Now the error message is a little different:
"Nested function does not have the same signature as delegate 'System.Func(Of Object)'.
I create a small program witch is a tcp client.I sent a asqii string to a tcp device over ethernet thads acts like a server.As soon as the device recieves the input string it will respond back with response data. The problem is i am not getting any response data back from the divice. The lenght of the string is max. 30 characters.When a use WireShark i see the reponse, but VB read nothing.I have read many threads with explenations about server/client connections but no example of a client with a tcp listener built in.I think thad the stream read is to late after the send instruction.
View 2 RepliesIm 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.
Im trying to make a basic Client/Server. The server can handle multiple clients and each client can send /recieve messages from the server.It works fine with just 1 client. but as soon as i connect with a second client. The first one no longer works. Anything sent from the first client is ignored by the server and when running the server in debug mode it gets errors from the client 1 stream.
Its as if the server will only hold one stream at a time and whenever another client joins the other streams are shut but the new client works fine. Even though i never close a stream.

Edit: FINALLY FOUND IT! Stupid mistake i forgot to put the ClientN variable up by one for each new client.So i was creating a new space in the array but erasing the first slot for the new client

View 1 Repliesi want to do partially clientserver chat application i have a idea that if user login to server his username and ip address shold detected and send to all the clients and in client list only username should display , ip address is kept hide , when user clicks any client it should connect directly to that client instead of server so that server load will be less only for conference chat we should use server?

View 11 RepliesI have been searching for days and months on youtube,google and everywhere else about how to create a Multi user chat system, where everybody can talk to each other all at once. Some people say Winsock is the way to go and others say TCP/IP is the way to go. I have little to no experience in either one of them. So if somebody can give me a really great turtioal or show me the guide lines on how to create a server and a client I would highly appreacite it. I am using Visual Basic 2008 express.
