Hogyan lehet bat-ban a cd-romot elérni betűjel beírása nélkül?

Szia.

Ha beállitod a cdrom változót akkor azt használhatod : %cdrom%-ként.

Mi kell hozzá ?

Egy progi, ami meghatározza a CDrom betüjelét (a progi csak az első CD-rom betűjelét határozza meg).

Illetve egy rutin, ami lekezeli a program kimenetét a batch-ban :

A program (PASCAL-ban) :

Program cd_char ;

Uses dos ;

Var ELSO_CDROM : byte;

{ Gets the first installed CD-ROM drive letter in a system.

Part of the Heartware Toolkit v2.00 (HTdisk.PAS) for Turbo Pascal.

I can also be reached at RIME network, site ->TIB or #5314.

Feel completely free to use this source code in any way you want, and, if

you do, please don't forget to mention my name, and, give me and Swag the

proper credits. }

FUNCTION First_CD_ROM_Drive : byte;

{ DESCRIPTION:

Gets the first installed CD-ROM drive letter in a system.

SAMPLE CALL:

NB := First_CD_ROM_Drive;

RETURNS:

0 : drive A

1 : drive B

and so on... }

var

HTregs : registers;

BEGIN { First_CD_ROM_Drive }

HTregs.AX := $1500;

HTregs.BX := $0000;

Intr($2F,HTregs);

First_CD_ROM_Drive := HTregs.CL;

END; { First_CD_ROM_Drive }

Begin

ELSO_CDROM:=First_CD_ROM_DRIVE;

halt (ELSO_CDROM);

End.

-----------------------------------------

Most a Batch routin :

@echo off

set cdrom=

cd_char.exe

if errorlevel == 0 set cdrom=A:

if errorlevel == 1 set cdrom=B:

if errorlevel == 2 set cdrom=C:

if errorlevel == 3 set cdrom=D:

if errorlevel == 4 set cdrom=E:

if errorlevel == 5 set cdrom=F:

if errorlevel == 6 set cdrom=G:

if errorlevel == 7 set cdrom=H:

if errorlevel == 8 set cdrom=I:

if errorlevel == 9 set cdrom=J:

if errorlevel == 10 set cdrom=K:

if errorlevel == 11 set cdrom=L:

if errorlevel == 12 set cdrom=M:

if errorlevel == 13 set cdrom=N:

if errorlevel == 14 set cdrom=O:

if errorlevel == 15 set cdrom=P:

if errorlevel == 16 set cdrom=Q:

if errorlevel == 17 set cdrom=R:

if errorlevel == 18 set cdrom=S:

if errorlevel == 19 set cdrom=T:

if errorlevel == 20 set cdrom=U:

if errorlevel == 21 set cdrom=V:

if errorlevel == 22 set cdrom=X:

if errorlevel == 23 set cdrom=Y:

if errorlevel == 24 set cdrom=Z:

echo A CD betüjele : %cdrom%

pause

---------------------------------------

Az utolsó két sor nem kell bele, csak azért van benne, hogy bizonyitsa a müködését.

Mindez letölthető :

Mi van benne :

- CD_CHAR.EXE

- CD_CHAR.PAS

- CDROM.BAT

Sok sikert.

Üdv.
