Hi,

Does exist any way to get information that is connected any active equipment into LAN connector ?

Thanks

Hi, check this WMI example, it uses the NetConnectionStatus property of Win32_NetworkAdapter:

$include "wbemdisp.inc"
$include "commctrl.inc"

OK - but I have not

$include "wbemdisp.inc"
$include "commctrl.inc"

Paja, follow the "Aurora and EBasic SDK Headers" link from my signature, find the latest links, download the pak for Ebasic and install it. You don't even need to restart EB.
If you have custom .inc files in the /include subdirectory, make a backup because 1521 (or less) new files will be added.
