BAT file tips

[tetza]

Here's an example for a batch program that works fine in windows 7.

All you have to modify to use the code is the 3 top lines: 1) Location of .mds file to mount; 2) location of DTLite or the standard edition of DT program; 3) location of program to run after mount.

Modify and it should automatically add a scsi drive, mount mds file to it, launch program to run while mounted and after closing that program: remove the drive again!

@echo off

set mds_file="D:\Some Directory\mds\Some Image File.mds"
set DTLite="C:\Program Files (x86)\DAEMON Tools Lite\DTLite.exe"
set Prg_run="D:\Some Directory\Project\Program to run.exe"

IF NOT EXIST %mds_file% goto missing_mds
IF NOT EXIST %DTLite% goto missing_DTLite
IF NOT EXIST %Prg_run% goto missing_PrgToRun
echo MDS location    : %mds_file% ok!
echo DTLite location : %DTLite% ok!
echo Program location: %Prg_run% ok!
echo.

%DTLite% -get_count scsi
set scsi_count=%errorlevel%
echo Number of scsi virtual drives already: %scsi_count%
echo.

echo Adding scsi virtual drive...
%DTLite% -add scsi
echo.
if errorlevel 0 goto get_letter
if errorlevel -1 goto error_add

:get_letter
%DTLite% -get_letter scsi, %scsi_count%

if errorlevel 0 goto mount_image

echo (Drive letter: D=3, E=4, F=5, G=6, H=7, I=8, J=9, K=10, ...)
