issues with dllcall and "getvolumeserialnumber"

[Guest dldaniele]

I would like to obtain the internal volume ID of the local harddrive. Using the GetVolumeSerialNumber function in Kernel32.dll, this should be possible. The following code receives an error in the call. Any assistance would be appreciated.

I am using the latest beta downloaded Dec 7, 2004.

$serialno = 0

$returned = DllCall("kernel32.DLL", "long", "GetVolumeSerialNumber", "str", "C:\", "str", "", "long", 0, "long", 0, "long", 0, "long", 0, "long", 0, "long", 0)

if @error = 1 then

Tooltip(" error in call " & $serialno, 0,0)

sleep (5000)

exit

endif

tooltip (" Drive Serial is " & $returned[4] & " ---", 0,0)

sleep (5000)

Thanks,

Dean

seems you need to supply some ommitted info... try this...

$serialno = 0
$returned = DllCall("kernel32.DLL", "int", "GetVolumeInformation", "str", "C:\",_
           "str", "", "long", 64, "long_ptr",  0,_
           "long_ptr", 2048, "long_ptr", 0, "str", "",_
           "long", 64)

if @error = 1 then
  Tooltip(" error in call " & $serialno, 0,0)
  sleep (5000)
  exit
endif
tooltip (" Drive Serial is " & $returned[4] & " ---", 0,0)
sleep (5000)
