{
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.
}
procedure List_Drives;
const
DRIVE_UNKNOWN = 0;
DRIVE_NO_ROOT_DIR = 1;
DRIVE_REMOVABLE = 2;
DRIVE_FIXED = 3;
DRIVE_REMOTE = 4;
DRIVE_CDROM = 5;
DRIVE_RAMDISK = 6;
var
r: LongWord;
Drives: array[0..128] of char;
pDrive: PChar;
begin
r := GetLogicalDriveStrings(SizeOf(Drives), Drives);
if r = 0 then Exit;
if r > SizeOf(Drives) then
raise Exception.Create(SysErrorMessage(ERROR_OUTOFMEMORY));
pDrive := Drives;
while pDrive^ <> #0 do
begin
if GetDriveType(pDrive) = DRIVE_FIXED then
Form1.ComboBox1.Items.Add(pDrive);
Inc(pDrive, 4);
end;
end;
