How To View Computers Connected To A Local Network
Jun 8, 2011
Here is my Prob- we have a main router from which we use a distributor or hub for internet connection distribution, ever computer connected automatically obtains IP address of format say - 180.50.50.xxx to access net connection.if any connected computer has different IP format than the given one, it cannot access internet.
i m new in .net programming i am wanting to develop a network application by which i can watch the screens of other computers connected in LAN,i can give permissions/privilages to other users.
Im coding an application that needs to list all computers inside my LAN, and get the status of the machines ex. Power On, Power Off.. in order to Wake On Lan, or Turn it Off.. im using Visual Basic .Net.I all ready listed all machines, now i need to get the status of them..
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:
how do i get list of all connected computers in local network i have tried through Active Directory and it gives all computer names whether connected or not. the main problem is few computers on network have dual operating systems and both have different name like different on xp (comp1 xp) and different on vista (comp1 vista) and when i try to ping a computer name like (comp1 vista) which is not active, but maps to its associated ip and return replying so i m not able to get true status of computer name as (comp1 xp) can also reply on ping
I'm looking into making just a simple Instant Messenger that will be accessed through the Login program i just made.I'm having trouble just creating the APP window at the moment. I get an eror when i try to add a message queue to it so help with this will.This is just going to be a simple Instant IM like program connected between two or more computers.Does anyone know about a source for this out there- or how would i go about codeing this?
I would like to ask how to connect our application to connected computers in a LAN.Will I use the winsock control?How can I run queries using a server database?Any answers are welcome.
Part of an application that I'm building searches the network that the current computer is connected to and returns a list of the IP & MAC addresses and the hostname. It is based largely on the post by richard__deeming at [URL] At the moment, it will only get the information about computers that are in the same workgroup, but I have several computers that need to be shown, that are joined to a domain rather than the workgroup. How can I get the program to find every computer on the network?
how can i detect in VB.Net 2010 that which network card I'm currently using for internet? Like Local Area network, Wireless Network Connection, Cellular Modem or Bluetooth Modem?
Is there any easy way to find out , which network am I connected to via programmatically. I mean we can check the Network is available through "My.Computer.Network.IsAvailable", same way can i find the name the network (Either Direct or via VPN).
I have to do something if my network is connected to a particular network.
I want to be able to change my network on the press of a button to another favorite network followed by the launch of a LAN based game and closing a set of pre-defined internet applications that will interrupt gameplay with "Lost connection" popups Basically I have two networks, on Internet, one only LAN (Both Wireless)I want to be able to switch networks and launch my game. I know the code for launching my game, but my question is....How do I switch network connections using my program?
i have a way to get all IP addresses on the local network, however I just want to get a list of computers on the local network who also have the program installed.Code I have to find local IP addresses:
Private Sub GetLocalIP() Dim strHostName As New String("") Dim Address As String = ""
I am writhing a program to replace a file in network computers. but the problem is in our network there is 32 bit systems and 64 bit systems. There are different files to be replaced for 32 and 64 bit systems. I have written a program to replace the file.if we give the target of the location (eg \drd001-dsk1C$Documents and SettingsAdministratorPlayerfilename where drd001-dsk1 is the computer name in the network) Is there any way to check if the system that i need to replace the file is 32 or 64 bit
am trying to get the IP address of all of the computers on a network. I know how to fetch the names of the computers on the network but I need to fetch the IP address to. I have a listview control with 2 columns 1 for the name of the computer (1st) and another column for the IP addres (2nd). I have the code so can the IP address be displayed in column 2
Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button1.Click ListView1.Items.Clear()
I have finished my program and now i am ready to deploy it. The only problem is it is a multi-user application. All i want to do is simply run the program with the database from a server, and have other local computers with the program access this same database. I know that you have to change the connection strings for the local computers, but how can i go along doing this?
How would i go about seting up a local database to store data so it can be used offline then to sync up with SQL server 2008 r2. i've got to the point of having a test project with a local DB that stores the data and a test SQL server but know idea how to set it up to sync with between databases.
I have an application that automatically updates addins for excel from the server to all the computers on our network. right now all i get is an error if excel is open, but what I want to be able to do is check if excel is open on each computer first and give the user a chance to save their current work then close excel. otherwise i cannot update their addins if excel is open.
I need to write a program that can be distributed over a network of 400 computers and that can be updated if necessary. How do i do that with VB if i can at all? What should i learn?
I want to develop a process that will monitor computers that logon to my network. Gather information such as computer name, time of logon and log out.The process would be located in the icon tray?
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()
