I need to develop a communication between two computer using wireless medium like wifi is there any namespace or control in .net which support this type of communication i know i have to define protocol to understand communication but i need start ......
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..
I wanna make an application in which i have to make two computers communicate each other. For example when a customer enters, his information is feeded in the computer at reception, and then this information is sent to another computer at upper storey, where the application detects the incoming data and populates in the relevant form.
How do I, programmicly, connect to a wireless network. I have already got with networks are avalible, now I'm looking into creating a 'Connect' button.
I'd like to build a program which shares files between two computers. My method for doing that is setting up a home network, basically, on one computer, put a file there, and share that file on the network. The other computer would then connect to the network (through my application) and find the file and read it. I know this is very long. I would just like you to help me start up.How do I create a wireless network ENTIRELY THROUGH VB during the initial setup of the application? I don't want the user to deal with creating the network himself.
I am using two computer to connect to each other via serial port, I have made a program in VB that allows me to read from the serial port then store whatever that character is to a variable. The only problem is I have to hit a button to read in from the serial port and pass the character to the variable. Is there any way to do this automatically?
I am currently improving an existing handheld application, this app makes live calls to our network over the wireless connection, if the wireless connection is not established I am displaying a holding screen to the user, this screen rechecks connection every three seconds.I want to put a button on this screen that closes down the application if the user does not want to wait any longer. At the moment I am using the application.exit command, however it continues to finish the first original thread (i.e. trying to process the dataset) before actually closing the application, I am looking for a way to kill the application there and then!
I am using the code below to test whether the user is connected using either a wireless or LAN connection. i.e. that the cable is plugged in, or the wireless is switch off. The code works fine for this. However, if you can spot any potential problems with this or you know of a better way I would be interested to learn more.
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?
I am starting a new project in VB, a card game modelled to be similar to a real card game.
I have the majority of the program planned out and have even started coding parts of it; my problem comes with the networking.This is a real-time card game (not turn-based) and I want to be able to play with real people (family mostly, so over LAN is what I'm after).
I have tried searching for code samples but I everything I have found seems more complicated than I feel is required for the task, introducing a lot of new concepts and not explaining them.
What I'm after is a simple way to exchange the information in real-time, I don't care so much for efficiency (at the moment) just ease of use - though if I need to wade through a heap of documentation I will. A perfect answer would tell me what the names of some of the controls/methods that would be appropriate are, even if it just re-affirms a bit of the complexity, you do not have to detail anything if you don't want to I just feel a bit at loss as to what exactly it is I am looking for!
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'm writing an app that sends messages over a network to another PC that processes the message and sends back a reply (e.g. a boolean or some other data). My network communication subs (based on WCF) just give me the ability to send a message to the other PC and process any received messages.The issue is that any response received is processed by my designated network message event handler sub, but I have no way of feeding it back to the sub that called for the original message to be sent.
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.
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 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?
I am trying to write a program to ping computers on my network to see if they are turned on. So far i have the following:
Code:
If My.Computer.Network.Ping("192.68.0.5") Then MsgBox("Computer is on.") Else MsgBox("Ping request timed out.") End If
If i use ip addresses, this works fine but i would rather use hostnames due to the ip addresses being dynamic (something which is outside my control). Using the hostname, it reurns "Computer is on" if the ping is successful, but if the hostname cannot be found, instead on returning "Ping request timed out", an error occurs as follows:
A first chance exception of type 'System.Net.NetworkInformation.PingException' occurred in System.dll
I have recently finished a console application and deployed it to several computers on our network for testing. As it is just an EXE a copied to the hard drives of selected computers for now. When the app is launched it writes info to an sql DB so I always know which computers it is on.
During the past few weeks I have modified this app at least 6 times (improvements, adjustments, etc)
It is a paint to keep going back to the computers to update it with the new version, and getting mixed up which version i am on - LOL I am looking for advice on how I would go about doing this automatically, for example, it would be cool if I just had to put an updated file in a repositry and clients would use this to update.
In Visual Studio, when I view the properties of my application>assembly information - I can set a file version. Is it possible to extract this info and store it in a variable? I would like to dump the in my DB. Also I could then possibly compare the file version of the launched app against an updated file in a network share folder.
