Automating the closing of the Creative Cloud signing and ABBY FindReader for ScanSnap 5.0 dialogs

Posted by jpluimers on 2021/01/06

Every time my scan VM logs on I get the dialog on the right.

Every time I finish an OCR scan, I get the dialog below.

There are two reasons I want to close the ABBY dialog:

  1. While open, it will keep both the original PDF and OCR PDF files alive.When after a while, Windows updates auto-reboots the machine, before clicking the OK buttons I have to manually check if the conversion succeeded before removing the non-OCR PDF.This is time consuming.
  2. While open, it still consumes a lot of system resources: about 100 megabyte for a simple single monochrome A4 page. Much more for complex, multi-page or colour documents.When scanning a lot of document this causes the system to run out of memory, after becoming much much slower because the truckload of Window handles and underlying threads drags Windows down.

I do not want to fully get rid of these dialogs, as often being aware of the progress is important, and I always forget how to re-enable things. If you can do without the dialogs, then try these:

Finding the Windows and controls

I did use one nice feature of AutoHotKey: their Windows Spy utility, which is implemented as a AHK script: [WayBack] AutoHotKey-scripts/WindowSpy.ahk at master · elig0n/AutoHotKey-scripts · GitHub. In the past this was a separate executable, so do not start looking for that any more. You can get it either after a full install of the [WayBack] Releases · Lexikos/AutoHotkey_L · GitHub, or by extracting from the most current from [] AutoHotkey Downloads.


This gets these for the Create Cloud and ABBY windows:

Automating the click

I contemplated about using AutoIt (freeware, but closed source) or AutoHotKey_L (the current active fork of AutoHotKey).

AutoIt is now closed source, forked in the past as AutoHotKey, which has a lot of half backed – usually poorly documented – scripts needing you to learn a new API wrapper around existing Windows API functionality.

So I reverted back to using the Windows API using Delphi: a simple repeat loop, to check for the existence of the underlying processes, windows and controls, plus some logic to terminate then the user stops the application (Ctrl-C, Ctrl-Break), logs off, or Windows shuts down.

Releated Windows API  keywords and posts:


I could have used AutoHotKey with these hints to get it working:


Note that when you run on MacOS, you need an alternative like for instance the video below shows via [WayBack] Stop ScanSnap From Prompting You When You Scan.

Batch files: deleting first/middle/ending parts of environment variables

Posted by jpluimers on 2021/01/06

Batch files are often a pain to write, but you cannot always rewrite them in PowerShell.

The pain below is about deleting parts of environment variables in batch files.

I’ll just redirect to and quote from posts that can way better describe this than I do:

  • [WayBack] Check if Batch variable starts with “…” – Stack Overflow made me find
  • [WayBack] windows – Batch – Delete Characters in a String – Super User
  • [WayBack] CMD Variable edit replace – Windows CMD –

    The variable _test containing 12345abcabc is used for all the following examples:

    ::Replace '12345' with 'Hello '
       SET _test=12345abcabc
       SET _result=%_test:12345=Hello %
       ECHO %_result%          =Hello abcabc
    ::Replace the character string 'ab' with 'xy'
       SET _test=12345abcabc
       SET _result=%_test:ab=xy%
       ECHO %_result%          =12345xycxyc
    ::Delete the character string 'ab'
       SET _test=12345abcabc
       SET _result=%_test:ab=%
       ECHO %_result%          =12345cc
    ::Delete the character string 'ab' and everything before it
       SET _test=12345abcabc
       SET _result=%_test:*ab=% 
       ECHO %_result%          =cabc
    ::Replace the character string 'ab' and everything before it with 'XY'
       SET _test=12345abcabc
       SET _result=%_test:*ab=XY% 
       ECHO %_result%          =XYcabc
    :: To remove characters from the right hand side of a string is 
    :: a two step process and requires the use of a CALL statement
    :: e.g.
       SET _test=The quick brown fox jumps over the lazy dog
       :: To delete everything after the string 'brown'  
       :: first delete 'brown' and everything before it
       SET _endbit=%_test:*brown=%
       Echo We dont want: [%_endbit%]
       ::Now remove this from the original string
       CALL SET _result=%%_test:%_endbit%=%%
       echo %_result%

    All the examples on this page assume the default Expansion of variables, if you are using DelayedExpansion then you can choose to change the variable references to !_variable! instead of %_variable%

    One advantage of DelayedExpansion is that it will allow you to replace the % character, it will still have to be escaped as %% but the replace action will then treat it like any other character:

    Replace the letter P with a percent symbol:
    Setlocal EnableDelayedExpansion

    Remove spaces from a text string

    To delete space characters use the same syntax as above:

    SET _no_spaces=%_some_var: =%

Batch file: check for (non-)existence of registry key

Posted by jpluimers on 2021/01/05

Small batch file that only deletes a registry key if it exists:

reg query %1 >nul 2>&1
if %errorlevel% equ 0 reg delete %1 /f
goto :eof

It is based on:

  • redirecting both stderr and stdout to nul (the >nul 2>&1 bit)
  • checking reg query with the appropriate errorlevel value for equality (equ operator) for 0 (existence); you can also use 1 for non-existence.

Based on:

Windows command prompt: decrementing loop

Posted by jpluimers on 2020/12/30

I needed a decrementing loop on the Windows command prompt, but that seems very hard from batch files without programming your own kind of while loop:

PowerShell to the rescue to loop back from and including 463 down to and including 290:

PowerShell -Command "for ($i=463; $i -ge 290; $i--) { Write-Host "Value " $i}"

This outputs:

Value 463
Value 462
Value 291
Value 290

In a similar way, you can execute a cmd command, but then you need to be careful on how to pass parameters: the \" is important to you can have quotes within quoted strings..

PowerShell -Command "for ($i=463; $i -ge 290; $i--) { & echo \"Value $i\"}"

gives this:

Value 463
Value 462
Value 291
Value 290
