Successfull .Bat file execution

Question

Hi,
I have a .bat file consisting couple of actions /tasks ...
Rem Task 1: Using ImageX to deploy a image stored on USB .
                    Imagex /apply /U:\install.wim /index:3 D:\
Rem Task2 : Copy a folder from USB to D drive
                    xCopy U:\Temp D:\Temp2
Now I want to add some logic into the bat file, for example if a task is interrupted (maybe be source disk is not available or removed, like USB or network resources etc) or there is no folder with name Temp (for example), can  I get a VB message box
with saying something went wrong, start again _???

If you write your batch file in a modular fashion then you can check for any criteria as shown below. You will have to write the individual code segments yourself.
@echo off
set result=OK
call :CheckDiskSpace
if not %result%==OK goto :eof
call :FileSize
if not %result%==OK goto :eof
etc.
goto :eof
==============
:CheckDiskSpace
. . . Your code goes here
if %Free% LSS 100000000 set OK=false
goto :eof
==============
:FileSize
. . . Your code goes here
if %Size% GTR 100000000 set OK=false
goto :eof
==============
