[RESOLVED] help ( detect pc that is on and shutdown it)

Dear friends, I'm developing internt kiosk program. I'm using vb.net 2008 and windows vista sp1. Is there anyone know the code where we can see which computer that is already turn on?

Example the client is pc 1 until pc 10
and the ip adress of each is 192.168.0.1 until 192.168.0.10

can I know/view which computer that is already turn on from server form?
if can, what is the code?

can anyone help me?

One more thing, Can I shutdown the computer from server?
For example: It's already closing time and if we are turn off computer one by one. It'll takes time and not efficient. So, can I just turn off the client computer from server? If can, can you give me the code?

Thanks for your help.......

You can ping the host you want to know if up with

http://msdn.microsoft.com/en-us/libr...tion.ping.aspx

If you are using tcp/ip client/server, then after you checked that client is up, you can send a string command like "Shutdown" or similar and when the client receives this, shutdown the pc.

I've read something similar before in
http://www.codeproject.com/KB/vb/RemoteShutdownX.aspx

Hope it helps

This might help on the shutdown...

If you doing the Kiosk software you can implement everything within the app.. You already have the IP linkup, and can use this to check if the client system is still online, and then you can use the ShutDown API call in the client part ..

Gremmy..

I'd use Terminal Server for the kiosk's. It can connect and run software securely

I like dglienna's suggestion for terminal servers.
This works very well, using the API to call the command:

Code:

---

Const SW_SHOWNORMAL As Int32 = 1
Private Declare Function apiWinExec Lib "kernel32" Alias "WinExec" (ByVal lpCmdLine As String, ByVal nCmdShow As Int32) As Int32


apiWinExec("tsshutdn /server:" & RemoteName.Text & " /powerdown", SW_SHOWNORMAL)

All you need to know is the name of the remote computer to shut down.
But I know that there are several ways to do it.

Do we need to import anything in the vb.net (for example import system.data.oledb when we want to connect to Acsess database)?

Do The Remote Name is the computer Name ?

What about if we use the ip address, is the code will be the same???

No
I don't think you'd need an import, if the computer shows up in the task "View workgroup computers", in the "My Network" window.

Yes
If a computer name/s is showing then, you can shut that computer down.

No
Use the computer name with this example.
Other examples suggested may use the ip address, and the port number.

Remote Shutdown
Please read the links that members have posted, when they try to answer your question.

just replace the servername with the server ip address. you don't need to specify a port. i shut down my server that way.
