Error Lookup Tool Friendly Output

Error-Lookup-Tool-Friendly.bat

@echo off
:: Note: Lines beginning with "REM" or :: are comments
:: Script by: https://github.com/thiojoe
:: Purpose: Creates a much more user friendly output for the Microsoft Error Lookup Tool (err.exe). It parses the original output and modifies the text.
:: Usage: Just call the batch file with command prompt along with the error code the same as you would with err.exe
:: Example:  error.bat 50
:: Recommended to rename this script to something shorter like 'error.bat'. Must be next to the lookup tool exe file.

:: SET THE NAME OF YOUR ERROR LOOKUP TOOL EXE HERE. Don't remove the quotes.

:: ---------------------------------------------------------------------------------------


:: Set the current working directory to that of the batch file so script can be called from anywhere and it will still see the err.exe file
cd /d %~dp0

:: Check if error tool is found or not.

    echo   ### Error ### : %ERROR_TOOL% not found. Either rename the .exe file or to match, or change the name in this script file.

(edited, as I agree with Cdztw; missing chr(34) & typo)

due to the use of enabledelayedexpansion use ! instead of %
(I also moved the temp.txt in case of write protection) If/else could have been used but personal preference

starting line 35:
if not %1@==@ %ERROR_TOOL% %1 > "%temp%\temp.txt"

if %1@==@ (
set /P CODE="Enter error code: "
%ERROR_TOOL% !CODE! > "%temp%\temp.txt"
)

last lines:
if %1@==@ pause
:: Clean up the temporary file
del "%temp%\temp.txt"

due to the use of enabledelayedexpansion use ! instead of % (I also moved the temp.txt in case of write protection) If/else could have been used but personal preference

starting line 35: if not %1@==@ %ERROR_TOOL% %1 > %temp%\temp.text

if %1@==@ ( set /P CODE="Enter error code: " %ERROR_TOOL% !CODE! > %temp%\temp.text )

last lines: if %1@==@ pause :: Clean up the temporary file del %temp%\temp.text

The file extension is wrong in the replacement codes: ".txt", not ".text".
And need to change the file directory in line 52 and line 94, from "temp.txt" to "%temp%\temp.txt", after that it should works perfectly.

Sorry for my bad English I'm still learning it...

Great tool! Thanks.

@digudc Might seem too obvious but have you actually downloaded the err.exe file from the link in the message?

@ThioJoe , I haven't yet. but I have found more details about it on your YouTube channel. So I am learning from there. Thanks a lot ..

Yea the batch file is just displays the info from err.exe in a nicer way, so you have to actually have err.exe in the same folder for it to work.
