If you have more then one network-connection, the functions returs an array, otherwise you directly get the MAC-adres

Hi SIlvio:

Function GetMacAdd()
local aMac, cRet

TRY
aMac := GetNetCardID()
CATCH
aMac := ""
END

IF VALTYPE(aMac) = "U" // no hay tarjera de red instalada
Return("")
EndIf
IF VALTYPE(aMac) = "A" // hay varias tarjetas de red
If LEN(aMac) = 0
cRet := ""
Else
cRet := aMac[1]
EndIf
EndIf
If VALTYPE(aMac) = "C"
cRet := aMac // una sola t de red
EndIf
Return(cRet)

Each ethernet card has a unique mac address .. it is the network card not the computer. Some computers may have more than one ethernet card in them .. that is why you may get the array with multiple addresses.

Silvo

There is NO good answer .. I am in State gov here with over 4k users .. One thing that I can tell you .. computers get moved, network cards go bad, infrastructure changes, new computers are always moved in and put in place, virus cause all kinds of problems and hard drives that have to be re-formatted ..

Just don't think a 'perfect' solution would be to rely on a Mac address .. just too much of a ( possible ) moving target. If you are looking at a small group of people using your application .. perhaps a 'dongle' attached to a serial, usb or parallel port wouild be better ..

Just my 2 cents worth ..
