Get List Of Connected Computers
Jan 9, 2009
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 am using VB to develop a WinForms application. This application should get all the computers from a particular Oraganizational Unit (OU) in the Active Directory (AD). How do I specify the particular OU in VB code? I would prefer to download some fields only from each computer's record.

i am trying to enumerate all IPs on my local network, but i am not having any luck. The only thing i have came up with so far is a really tedius "get my own ip and scan the subnet with pings" which surely isn't the best way? I am really only trying to get the ip of a tivo box, and i can determine it's a tivo by mac address or name. My router lists the "computer name" of the tivos as a long string of numbers with the prefix "tivo".What about broadcasting a ping packet? I could also attempt to connect with telnet to port 31339 on every one of them.

I've run into a bit of a problem using Async ping. Basically, I want to ping computers in the list before I run the next bit of my program. The computers who I can ping are added to a list and that is used in a background worker. Trouble is can't seem to work out how to wait until after pinging ALL computers in the list, either successful or timed-out. Is there something a long the lines of 'If Async Ping is running'?
Private Sub pingCompleted(ByVal sender As Object, ByVal e As System.Net.NetworkInformation.PingCompletedEventArgs)
If e.Reply.Status = Net.NetworkInformation.IPStatus.Success Then
complist.Add(e.UserState)
Else
'do nothing
End If
End Sub
I need the next bit to wait because if 'complist' is changed while it's being used I get collection errors.

WebBrowser1.Navigate("http://192.168.15.x/DHCP_Static.asp")[code]....
Which i though was suppose to list connected client but logged on my DS and didnt listed it up. Maybe it doesnt list DS?

My issue, however, is connecting to the wireless laptops as well.
[code...]
I need to grab a list of all networked computers, and I definitely include systems on the wireless
network in that list. I'm just not sure how to approach this. Being able to enumerate through a
'tree' of all networks and systems available would be a major plus.

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")

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 have alignment issues with my application's printout. It isn't same in all computers, or printers. I want to use the whole A4 page in my app without any margin or other spaces. So I set all margins to 0.If I set OriginAtMargins to false, margins are still active for the page, or setting them to 0 is useless? The actual question is should I also set the HardMarginX and Y? I must get rid of all spaces for the correct printing.

i have a strange problem with a VB.Net Windows Application. On my computer(the development PC) it executes the newest version of the exe and dll's but on the computer of my fellow(he is not a developer and cant debug it) an older version is executed. He has overwritten all files with the new version:
I dont know where to start looking for the reason.
EDIT: the first thing i've done was to restart the pc of my fellow but that was of no use.
When is a dll installed in the global assembly cache? Because i've searched for it in the gac with gacutil.exe but not found:
C:>C:WINDOWSMicrosoft.NETFrameworkv1.1.4322gacutil.exe /l Rule.dll
Microsoft (R) .NET Global Assembly Cache Utility. Version 1.1.4318.0
Copyright (C) Microsoft Corporation 1998-2002. All rights reserved.
The Global Assembly Cache contains the following assemblies:
The cache of ngen files contains the following entries:
Number of items = 0
I've also looked into the assembly folder but not found any of these dll's there.
Additional info: one of the dll's is loaded dynamically in the codebehind:
System.Reflection.Assembly.LoadFrom("Rule.dll")
The others are referenced in the particular project.
