IRC Client In VB?

Feb 18, 2010

I've been working on my own IRC client which, I'm happy to say, I now have working.There's really just cosmetic changes to make.Here's a small example of what info I'm getting during testing. It's all right, but it's ugly and hard to read:

Wombat!Colgate@41E59A1.54501D34.1FE90F1D.IP PRIVMSG #chatz :ACTION ducks
Trixar_za!trixar@founder.chatznet.co.za PRIVMSG #chatz :oi, I'm bored
Trixar_za!trixar@founder.chatznet.co.za PRIVMSG #chatz :Come on, attack me again

That there is <user's nick>!<user's name>@<user's host> <raw IRC command> <target channel> : <message> In the case of the top line with ACTION ducks, the user was using action text (in mIRC, she typed /me ducks)What I'm looking at doing is removing everything in those lines from the first ! to the end of the word chatz so that the messages appear as

Trixar_za :Come on, attack me again

Also, I want to create tabs for each channel and private message received on the incoming data stream.So, if incoming data contains "PRIVMSG" Then open a new tab that has a multiline textbox that contains the incoming data.For the most part, I have no problem with the logic for this... but creating the new tab and populating it with the needed controls is where I have problems.

Client-Server-Client Multithreading - Instant Message Another Client

Jun 21, 2010

We are creating a Who wants to be a millionaire style game in VB. Our server is pulling information such as questions and answers from a Access Database and sending them to the contestants (Clients). All transfer of information is directly from the server to each client. One of the "Life Lines" we want to use is "Ask a friend", where one client is able to Instant message another client for a short time to get help on the question.

Writing A Program With 1 Client And Server Where Client Side Creates A Text File

Dec 1, 2008

I have been reading through Atheists posts in regards to client-server and TCP client/server connection's. But how do i go about writing a program with 1 client and server where the client side creates a text file.Once the server sees there is a text file it connects and downloads it to itself or the client pushes the text file to the server.Once on the server i will read the text file and put its info into a sql db.

SMTP Email Client Fails On Local Machine Needs To Run On Client

Jun 29, 2010

I have an application that takes a series of reports and sends them as attachments in an email to a specified group of email accounts.

When I run the Java version of this using apache commons and the same setting, the email is sent. However, when I run the VB.NET version of the code, it fails on my local machine and on the client machine.

I have a VB.NET web application running on a server that uses similar code. I tried that code locally and it fails. Yet, the web application is working perfectly.

Why is it that the Java application can send the email, but the .NET application cannot?[code]....

Aug 18, 2009

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

VS 2010 Client-to-Client LAN Messenger?

Jun 15, 2010

Can't find any free ones so thought I would work on one on my own for the heck of the learning experience with TCP stuff.I'm about ready to start on the messaging aspect of it.The biggest thing I'm wondering about is figuring out when people are online.I'm not too sure how the whole thing works.Say I turn on my messenger. Would my messenger just send a message to all IPs on a certain port to say I'm online and then wait for a message back from the IPs that can return messages and then figure out who is online that way?

VS 2008 TCP Server / Client - Client To Send The Server 4 Numbers - Depending On The User's Choice

May 9, 2009

how 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])

VS 2008 : TCP Server/Client "send Hashtable To Client App"?

Jul 15, 2009

i have been working on a chat program Server side and client side i have most of the features i was asked to put in but then once i got most of the bugs out i noticed something the server admin could send whispers and alerts to single users but then when you try do do it on the client side it wont work so i looked through it all and found my issue the user list on the client is only a list of the names in server hash table so i was wondering how do i send the hashtable and all of its data E.G. user connection information to the client so that it can send commands to individual users like the server side can

vb
Public clients As New Hashtable()
' This subroutine checks to see if username already exists in the clients
' Hashtable. If it does, send a REFUSE message, otherwise confirm with a JOIN.

[code]....

i tried to send the hashtable over the same method used to send the user names to the client but it cannot convert the hashtable to a string so that wont work so my question is How do i send the hash table to the user from the server then display the username on the client ??

Server/Client - Basic Tcp Server/client Application

Mar 30, 2009

I've basically made a basic tcp server/client application. The thing is that I'm behind a router and so will be the other people that use my clients. I've had to use port-forwarding or the software "rinetd"to run quite a few applications online.

Let me explain: I'm on a lan network that connects to the internet. Whenever I want to host a server - for instance a basic ftp or http server. If I give my external IP to anyone, they won't be able to access my server. Even if I portforward, it doesnt work. I have to use rinetd here. For other applications, portforwarding works. I'm not sure how these things work at all.

Anyway, my issue now is that I have created this server/client application. I'm having serious doubts that if I run the server, I'll have to either a) portforward or use rinetd to get people to connect to my server. IF I need to portforward, that's fine. However, using rinetd would really suck... My 2nd concern is as follows: IF the person running the client is in a similar situation as me (i.e he's on a lan that has a router which connects to the net), will he have to portforward or use rinetd as well? If he portforwards that's fine. But I don't think I could get people to use rinetd.... Also, if there are more than 1 person on a lan trying to connect to my server, there is a big problem when they try to portforward: they will only be able to allocate one of their internal ip to that port, and the others won't be able to connect, right? How does this work? I mean, I use many softwares like msn/skype/(some games)/firefox that do not need portforwarding/rinetd. Yet they work. My housemates(other people on the lan) use the same softwares, and it works fine. There's no clash/probs watsoever How come these run fine?

Anyway, back to my issues. Given I have no knowledge about how the above work, I was wondering whether there was a way to host a vb .net server application on an external website (external to my house) so that I might *avoid* the above mentioned problems, and to what extent that would be a sound solution.

.net - Way To Have A Client Use That Interface?

Mar 6, 2009

Let me give a scenario then see if anyone has a solution / work-around.I've got a library (DLL) that contains only classes. In another library, I've got interfaces that the classes in the first library implement. Clients will always reference only one version of the library containing the interfaces (always the latest one) - and only additions will be made to those interfaces (more interfaces / methods). Also, there will only be one version of that interfaces library - so that clients don't need to update references (the interfaces library will be loaded through reflection - so the usual probing rules do not apply, we can only load what the client specifically asks for). The library implementing the interfaces will have multiple versions that different clients reference at the same time.

The problem occurs when a client assembly is referencing an old version of the implementation library. It creates an object from a class type in the implementation library - then passes it to another client assembly. That client assembly uses the latest (and only) version of the interfaces library and attempts to cast the object passed to it with the appropriate interface type. This cast fails with the exception 'System.TypeLoadException: Method X in type Y from assembly Z does not have an implementation'. I expected this exception because in the new version of the interface (same version number - old library clobbered), method X is defined, but even though the old version of the object that is passed contains metadata that says it implements the corresponding interface, the mapping fails on the new interface method X because it doesn't have any implementation in that class.

So, my question is this; Is there a way to have a client use that interface, but only cause an exception when a method that is not implemented on the referenced object is called (rather than the exception being generated when the referenced object is cast to the newer interface type)?By the way - late binding isn't an option because we want intellisense / compile time type checking ... Also, I know how to do this with function pointers and wrapper classes - I was just hoping for a better solution that is more in tune with regular .NET types.

Get Client Ip Address?

Mar 1, 2009

i am actually developing an application which runs on the server .The computer is configured as a Dial in Server and allows clients to connect to it via a regular dial up connection.In The application i need to determine the ip address of the client who is connected to me at that instance.I have tried using the following code

Dim hostname As IPHostEntry = Dns.GetHostByName(TextBox1.Text)
Dim ip As IPAddress() = hostname.AddressList()
TextBox1.Text = ip(0).ToString()

but it gives me some socket creation error when i type in the name of the client in the text box . Is there any other way to determine the clients ip address who is connected to me at that moment. Note: i am using the Modem for connections not the LAN adapter.
