Develop Ip Messenger App For All User Connected In LAN
Dec 29, 2011
I want to develop a Ip messenger app in VB.Net for all the user connected in LAN.I am able to send message to user according to IP Address.I want a functionality to list all the user which are connected(Using) to this app so that they can receive message.How to check whether the person at other location is connected to the app or not.I first used System. Net. NetworkInformation.Ping and PingReply to get whether user is available or not.[code]Also error is returned after delay if I write this code in try catch block. Is there any quick way to check whether there is a listener at a particular given port?

I have a requirement that users be connected via the LAN for a small service I am writing. Simply check My.Computer.Network.IsAvailable isn't enough because that will detect any network (e.g. wifi). I need to check whether or the user is LAN connected (and can therefore connect to an Oracle DB)

Using the code below i will get all network interfaces wich are enabled and functional on the machine.
Private netIntrfc As NetworkInterface() = NetworkInterface.GetAllNetworkInterfaces()
For i As Integer = 0 To netIntrfc.Length - 1
If netIntrfc(i).OperationalStatus = OperationalStatus.Up Then
[code]....
But my problem is how to get the default one, the one(ethernet adapter) through wich user is connected to internet?I need to change some settings of default(through wich user is connected to internet) adapter. settings i change through registry so i could sample add same settings for each network interface but that could cause problems and makes no point then?
EDITED:for now i have done like code below, so if this can help someone other...
Dim u As UdpClient = New UdpClient(System.Net.Dns.GetHostName, 1)
Dim localAddr As IPAddress = CType(u.Client.LocalEndPoint, IPEndPoint).Address
Private netIntrfc As NetworkInterface() = NetworkInterface.GetAllNetworkInterfaces()
[code]....

I have developed an application using vb.net. This application will run on approximately 15 machines at the main office and also roughly 10 machines spread over 3 different locations. I am using SQL Server Express edition in the backend. I deployed the application on the network using caspol but it is extremely slow. The Company Manager's perception is that because a script will invariably have to be deployed on each client machine to configure CASPOL, that the solution is not viable.
What is the best method to develop and deploy a multi-user desktop application?

I am trying to develop a simple math calculator that will allow the user to input the right-hand-side (RHS) of an equation into a textbox on the application and have the application evaluate the expression for a given value of x, which is also input
into the application by the user via another textbox.For example, if the user wants to evaluate the following expression,
y = 3 + 4*x + 5*x^2
then they would input into the textbox the RHS of the equation
3 + 4*x + 5*x^2
and then enter a value of x into the another textbox and click on the calculate button.I tried this:
answer = EquationTextBox.Text
but it doesn't work.

On my program I am trying to make a ToolStripStatusLabel's text change to "connected" if connected to a network and if not connected to a network change the text to " Not Connected" then I don't know how to display a image if connected to a network or not connected. So if the computer is connected to a network I have a image that I would like to be displayed next to the ToolStripStatusLabel. And if not connected to a network, can the program display a different image? I tried this:
My.Computer.Network.IsAvailable=True(ToolStripStatusLabel2.Text "Connected")
My.Computer.Network.IsAvailable=False(ToolStripStatusLabel2.Text "Not Connected")

One of the companies I support has a group of people on an isolated network. No access outside their subnet at all. They are on multiple floors and have asked if they can get something like Office Communicator, they don't have email and are tired of making phone calls every 5 seconds. Only there is no budget for Office Communications Server, they are cheap. I can't find any instant messenger programs that connect two computer directly so I thought I would write my own, seems like it would be fun. All the samples I have found on here are more like chats then direct communication between two computers.

I have multiple chat programs (e.g. MSN, Yahoo *Messenger*, ICQ etc.) where the login name is stored, and I only need to type in the password to log on to in. But it's a hassle to open each and every chat program then login.So, I attempt to write an application where it fetches all these stored chat program's user name into one application under a single window/form (similar to [url]..., but I'm doing a desktop app version). User can then login in to any chat program in one application.The first step is: how can I get or where do I look for the stored user name of a chat program? I looked into Credential Manager, but it isn't helpful.
