Disconnect Button For My IM Client?
Aug 27, 2010
I am currently working on a messenger client that connects to a server then back to the clients for full chat room support.I have it operational however when you close the client before connecting to server it closes normal, if you close the client after you have connected to the server then the client dissapears but it is still running in processes. To make it worse if you close the process it then kills the server.What I need is a disconect button code so it will stop crashing it.Here is my code Client:
Imports System.Net.Sockets
Imports System.Text
Public Class Form1[code]......

I am working on a code for a chat client/server and I have it all working, I can connect and chat locally and global. The problem I am having is that when someone just hits the X in the corner to exit it crashes my server as well as the fact that if someone wants to they can make their username the same as someone elses.

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'm trying to make a chat room that when the user connects hes added to a listview. Im having trouble on how would i remove that client when the user disconnects.
I understand that you can do ListView1.Item.RemoveAt(Sender) but that would not work because RemoveAt only accepts integers.

Searched quite a bit and am having trouble finding how to have the server catch the client has disconnected. When the server detects the disconmnect it goes bonkers. Would like to Try and Catch ex so I could gracefully handle it.

I am working on a chat client and server, and so far it works well, but when I close the client, the server throws an exception because it continues to try to do processes on the disconnected client. I have tried adding clientSocket.Close() in various places throughout the client and server with no luck. Does someone know how to add the disconnect code to either the server or client with this code?Server:
Imports System.Net.Sockets
Imports System.Text
Module Module1

I have a VPN connection set up on my computer. I am trying to make a button in my VB.NET program to connect/disconnect to/from the VPN connection. I have tried making a shortcut to the VPN on my desktop and calling it with the Shell method but I get an error saying file not found. I have also added the shortcut extension ".lnk" and still have the same error.

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.

I have a page that is based on a Master Page. The page has AJAX contolled tabs and on one tab I have 2 panels, each with 1 button. Only 1 panel is visible at a time. I am trying to get the button on the visible panel to be the DefaultButton so that when Enter is pressed the click event is fired off. The issue that I am having is that I get this error no matter what I try: The DefaultButton of 'form1' must be the ID of a control of type IButtonControl.I have tried setting the Default Button property of the panel to the buttons client id and to its unique id.

I'm viewing reports on a VB.net form using CrystalReportViewer. Once a report is opened, the Access database that is used within the report is locked (i.e., the Access MDB file can't be deleted). Even after the report is closed, the database stays locked until the VB.net app "ends". This is a problem because I want to be able to delete the MDB file at some point while running the app and can't. The VB.net app starts by opening a form named "Startup". No database connection occurs here. A button is pressed using this [code]I must not be properly closing the CrystalReportViewer or the Report form.How do I close the Crystal report and unlock/release the Access database?

I have a PC with four LCD monitors attached, but often I leave it unattended and need only one monitor running. I've set up power strips so that I can flip one switch on a power strip to turn on or off the other three monitors. The problem is, when I turn off the other three monitors, the computer makes the disconnect sound every few seconds. you can go into Control Panel->Display->Change display settings, and under 'Multiple displays' disconnect the monitors you are not using, and them reconnect them when you need them again. However, this is time consuming to do manually.can I program this in VB .Net, i.e. is there a Class or some registry keys that I can use to connect or disconnect monitors the same way as through the Control Panel?

Lets assume that I have a game server in my computer.
I download a compiled game, server/client side.
The player starts the game and it keep sending and receiving data from the server.
Lets assume now, that I think that the player is using some bug and winning all the rounds. How can i disconnect his IP from the server port? I have seen some people using some kind of DLL to do the job. Its something like iphlpapi.dll ... i dont remember well.

I'm using the chat program provided in the 101 examples kit, and have modified it a bit to suit an app i'm fooling around with. I have come across a problem...
When the client side crashes, the server side doesnt realize that the connection has been lost. Is there any way for the server to poll its clients table to figure out which streams are still open?

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.
