Hi,

Any idea how the labview program can check whether the PC is online or not, before opening the Web browser?

Any help will be appeciated,

Hello,

You mean you want to know if the PC that is running the program has a web access ?
I have never used any network function but I saw VIs to connect to a POP3 mailbox, maybe you could use one of these just to try to get connectto a server and see if you get an error. Disconnect your PC from the network see what error code and string you get and implement this in your program.
This is certainly not the nicest solution, but an idea...


you said "ANY help would be appriciated" 🙂 ... just kidding... hope the idea will somehow lead you to a solution.

Here is a vi that uses a .vbs script file to determine if the network cable is plugged in to the computer. You need to be running windows and have scripting enabled. I ran this on my WinXP media center machine. I had to change the location of where windows finds the cscript.exe file versus my win2000 computer at work. This is in 7.0 format.

Hi

You could also use in my opinion the most simple way, just ping some server over the network.

You can use one of this solution for ping:
