con MsgInfo( STR( VolSerial( "C:" ) ) obtengo "2696837951".
Entonces no me queda claro porque HDGETSERIAL me da otro
numero diferente ???. Creo que tendre que cambiar de todos modos.

Gracias

with MsgInfo( STR (VolSerial("C:") ) I get "2696837951".
So I'm not clear because HDGETSERIAL gives me another
different number???. I think I'll have to change anyway.

thanks

It's impossible to know why it gives a different number, without seeing source code of HDGETSERIAL

Happy HMG'ing

OK, Ya me funciona el ejecutable. ( quite la funcion MAKELAYER )
La funcion HDGETSERIAL("c:\") la he estado utilizando desde hace años pero no recuerdo
de donde la obtuve, ademas esta en C y siempre despliega el "warning" al compilar.

OK, I already runs the executable. (Remove the function MAKELAYER)
The function HDGETSERIAL ("c: \") I've been using for years but can not remember
where I got it, also is in C and always displays the "warning" to compile.

Que hace esa funcion Andy ?.

Hola Andres

Previous tests indicate that: A0BE7B3F = 2696837951 = -1598129345

I'm not a mathematician, but I know :

A0BE7B3F = 2696837951

is correct, but

2696837951 = -1598129345

not !

If your function(s) are in binary format ( .lib or anything else ) it's difficult to help you, I think

Yo reprobé matematicas, asumo que es igual en base al resutado obtenido.
I failed in mathematics, I assume it's just based on the result set obtained.

It's impossible to know why it gives a different number, without seeing source code of HDGETSERIAL

While digging my moldy archives, found two HDGETSERIAL functions

No any neat and useful hint but as far as I see ;

if function used by Andres is the same and
function invoked from other than current drive and
no parameter ( drive code ) specified

than it returns a negative value.
