Title: enumerate Drives on a Computer?
{
Adds all fixed drives into Combobox1.
To enumerate another type of drive,
i.e all CD-ROMs just change the DRIVE_FIXED constant to DRIVE_CDROM.
Fügt all fixen Laufwerke in Combobox1 ein.
Um z.B alle CD-Rom Laufwerke zu ermitteln,
einfach DRIVE_CDROM anstatt die Konstante DRIVE_FIXED nehmen.
