Hi Gilbert,

what do you want to do? Your question is incomplete, lacks any detail. What do you have already? Show us your code and we might show you a solution.

Hi,

        Thanks, I want to make a program with labVIEW, the program can read all the data size(received ant sent)  through local network card (LAN), I don't know how to do this, the basic function is similar with " Local area connection status".

Hello Gilbert,

I'm not familiar with this function, but for a network connection there are several options, which protocol do you use?

Hello,

         Thanks, I want to get the data size through LAN back, and display for user, how many data in and out !

See enclosed !

Whow,

that is deep down Windows. I *think* that you have to do a win32.dll call, but i'm not sure.

sorry,

Ton

Maybe a .vbs script file will work. This reads raw performance counter data. You may need to read the initial values when you start labview and then subtract them from the current readings.

Or use netstat command from command prompt.

Here is a 7.0 file run on windows XP.
