Read Networking state (e.g. from Windows Task manager)

[H.H.]

Hi

I need to get the status on a specific network attached to the computer. I have several network adapters attached to the computer. I can get the information from the Windows Task Manager manualy, but I need LV (7.1) to do it.

Perhaps its possible to get the info from the regdb, but I havent found it

Can anyone help??

One simple way is to use System Exec.vi to obtain this information using the ipconfig utility. Use the command "cmd.exe" and the input string "ipconfig /all[CRLF]" (where [CRLF] is a carriage return + line file). This will output something similar to the following:

C:\WINDOWS\system32>ipconfig /all

You can parse this output string and to determine the status of your adaptors.

[m3nth]

The more basic information of just your different IP #'s and Computer ID's can also be obtained by placing the String to IP function and then right-clicking to selecting multiple outputs. This yields a U32 array that can be converted in a for loop using the IP to String function to return names and dot-notation IP #'s.

Also if you're looking for the connection status of a specific device on your network there is code availalbe (I believe it's on NI's website somewhere) that will let you monitor the ping time natively (using raw winsock calls, as compared to performing a shell exec of the ping command)
