Relaunching a windows app using a batch script

We recently had need to restart an app server exe automatically when the demonstration license it was running on caused the server to close regularly, annoying everyone trying to learn the system. We had need of a script (YAY) to check if it was running and restart it when required.

Requirements:

  1. Check to see if the app is running on start if not running, start it.
  2. wait for some period of time (60 seconds)
  3. Check to see if the app is running, if not running, start it

Flourishes:

  1. Date app last restarted is displayed in title
  2. ability to close script with a button press
  3. ability to cancel wait time and relaunch app now
  4. ability to log when app was restarted

Working on it:

checking if a process is running:

It turns out that checking if a process is running is relatively easy:

tasklist /FI "IMAGENAME eq appServer.exe" | findstr "appServer.exe"
if %ERRORLEVEL% == 1 Echo No server Process found
if %ERRORLEVEL% == 1 goto start

and of course, now you have to choose:

choice /T 60 /D y /C YABCDEFGHIJKLMNOPQRSTUVWXZ /N >NUL
if %ERRORLEVEL% == 1 goto loop

now we start the exe

start "" "C:\Program Files (x86)\AppVision 4.0\Bin\appServer.exe"

Set the title

title appServer (re)Started at %NowDate% %NowTime% (Press X to exit script before closing appServer.exe)

Pulling it all together:

@echo off
title appServer (re)Launching script started at %time:~0,2%_%time:~3,2%_%time:~6,2% (Press X to exit script before closing appServer.exe)
pushd "C:\Program Files (x86)\AppVision 4.0\Bin"

:loop
timeout 2 >NUL
rem ping 127.0.0.1 -n 2 >NUL
echo.
tasklist /FI "IMAGENAME eq appServer.exe" | findstr "appServer.exe"
if %ERRORLEVEL% == 1 Echo No server Process found
if %ERRORLEVEL% == 1 goto start
echo Server process found at %time%, waiting 60 seconds
echo.
rem timeout 60
rem ping 127.0.0.1 -n 30 >NUL
choice /T 60 /D y /C YABCDEFGHIJKLMNOPQRSTUVWXZ /N >NUL
rem echo %ERRORLEVEL%
if %ERRORLEVEL% == 1 goto loop
goto eof

:start
set NowTime=%time:~0,2%_%time:~3,2%_%time:~6,2%
set NowDate=%date:~10,4%_%date:~4,2%_%date:~7,2%

cls
echo starting
start "" "C:\Program Files (x86)\AppVision 4.0\Bin\appServer.exe"
title appServer (re)Started at %NowDate% %NowTime% (Press X to exit script before closing appServer.exe)
choice /T 10 /D y /C YABCDEFGHIJKLMNOPQRSTUVWXZ /N >NUL
rem ping 127.0.0.1 -n 11 >NUL
goto loop

:eof
popd
echo script finished due to keypress
rem pause

Opening ISO CD/DVD image files

We often get asked how to get information from an .ISO .bin or other type of CD / DVD image file, so here are the easiest ways we know of.

  1. Mount the ISO as though it was burnt to a CD/DVD and inserted into a drive on your PC
  2. Extract all files from the image to a directory on your PC

Mount the CD/DVD Image

Download and install Virtual CloneDrive from slysoft, double click on your file and start browsing.

Extract the files

Download and install Universal extractor, then right mouse click on the file and choose extract, select a location, and kick back and relax for a minute or two while the magic happens.
