• Daniel Trunt pointed out an error in the Parameter Files
section of my batch file Input Validation page:
FINDSTR /R /C:"[""()&'`]" "parameterfile"
should actually be
FINDSTR /R /C:"[\"()&'`]" "parameterfile"
How to escape doublequotes in
's "filter string" depends on whether the
(Regular expression: use
) switch is used.
I retested the rest of the code on that same page, and found that it is not possible (do I hear a challenge?) to safely parse a parameter file while allowing doublequotes and ampersands; so I removed the code that tried to do just that, and for now I recommend using a different scripting language in that case.
• While testing the code I "discovered" a feature I thought was missing in
FINDSTR (RTFM?): though one cannot use
(string1|string2|string3) like constructs in
FINDSTR's "regular expressions", one can omit the
/C: switch and use spaces for delimiters between choices.
E.g. instead of the "true" regular expression
FINDSTR one can use
"string1 string2 string3", if and only if string1, string2 and string3 don't contain spaces.
So instead of
FINDSTR /R /C:"(string1|string2|string3)" one would use
FINDSTR /R "string1 string2 string3"

• Several "classic" batch file websites that I link to on my own site are discontinued, go blank, disappear, get on milk cartons...
So a while ago I started marking some of them as lost, asking for feedback if any of them are found elsewhere.
Today Matt Burnham notified me of a mirror for Benny Pedersen
up, one less to go...

is a new, simple demo script to lookup airplane data by entering their registration number.
The HTA uses Airport-data.com
to provide a photograph of the airplane, and a link to more data.
For now, the HTA can only be used in Windows 7 and earlier versions, because security restrictions in Windows 8 and 10 block fetching the data from the website.
Note that the author of this script is in no way associated with Airport-data.com

is the VBScript version of RipCD.bat
I added an option to run the script in interactive mode, i.e. prompting for all missing information instead of aborting with an error message.
I also added support for translated/customized messages:
- run the (English) script with the
/L switch only to generate a "template" file named RipCD.en
- open RipCD.en and translate and/or customize the messages after the equal signs
- save the modified file with a different extension (e.g. RipCD.nl for a Dutch translation)
- run the sript again with the command line switch
/L:extension to use your translated/customized messages (e.g.
/L:NL to use messages from RipCD.NL)
When you download the ZIPped script, the Dutch translation is included as RipCD.nl.

has been updated: it now accepts a remote computer name or IP address as an optional second command line argument.

• A minor update of CheckVarsVBS.bat
: while the list of all
variables is sent to Standard Output, the summary of unused
variables is sent to Standard Error instead.
This allows you to display the unused variables summary only, by redirecting Standard Output to the NUL device:
CHECKVARSVBS.BAT vbscriptfile.vbs >NUL
November 19, 2015
has been updated: by default, the new version will exclude any files that are listed as "Disallowed" in robots.txt
Use the new optional switch
to ignore robots.txt, i.e. to not
exclude any files listed as "Disallowed".

• It has been on my ToDo list for a long time, and today I finally wrote a tool to check my own VBScript code for unused variables: CheckVarsVBS.bat
To write VBScript code I use VbsEdit
, which will warn me if a variable I use
is not specified
(provided I use
in the script), but it won't warn me for unused
variables — hence this batch file.
is a really simple batch file that lists the variables in the VBScript code that are specified with a
command, then counts and shows the number of times each variable is used in the script.
If unused variables (count 0) are found, a second list with only those unused variables is displayed.
The batch file requires my RxGrep.exe

• Yesterday I stumbled on a great blog post by "elrobis" explaining how to use VLC to rip CDs
Though the original code works great, I did not like the fact that the path to VLC.exe and the CDROM drive letter were hard-coded.
So I added "some" code to automatically detect these.
Well, the added amount of code turned out to be far more than the original code, because I stumbled on many issues while testing on my own multiple-CDROM system.
The resulting RipCD.bat
only requires a single argument: the path to the output or target folder.
In case you have several audio CDs loaded simultaneously, you can also specify the CDROM drive to be used.
And if you want less screen output and you don't care if existing files are overwritten, you can use the optional command line switch

(Basic Hardware Inventory) has been updated once more: a bug in the NIC Speed detection has been fixed, and the WMI query for physical network adapters has been simplified.

• If you view this page on a desktop computer you may not even notice, but the layout of this page has been changed to accomodate mobile devices.
The rigid tables have been replaced by floating blocks, that will rearrange themselves vertically for small screens.
Try this page on a mobile device, then navigate to one of the older news archive
pages to see the difference (the archived news will be restyled too, but the priority is low).

(Basic Hardware Inventory) has been updated: a bug that made the HTA trip on empty PATH entries has been fixed.
• I am sorry to inform you that the solution for the IE Favorites Bar issue (see news item of October 15, below) did not work after all.
The issue is non-existent on my own computers, as only Internet Explorer versions 8 and 9 seem to be affected; so I cannot really test any solutions.
Since I had found a completely unrelated issue in IEPwdDlg.vbs
(bad copy and paste of error handling code), I had to update the code anyway, so I took some time to experiment with the Favorites Bar in IE 11.
I found out that its visibility is registered in the following registry key:
So I added some code to IEPwdDlg.vbs
to check if the Favorites Bar is visible; if so, it is hidden before the dialog is shown, and restored after it closes.
I hope this will solve the issue, but as noted before, I cannot test this myself.
• Steve Noble reported that for IE's Links Explorer one can use a similar technique on the following registry key:
I modified IEPwdDlg.vbs
October 15, 2015
• Some time ago, Steve Noble reported an issue with the Internet Explorer based dialogs in VBScript: if the Favorites Bar was visible in old versions of Internet Explorer, it would also show up in the dialog window, pushing input fields or buttons below the lower border.
Yesterday, he sent me a brilliant solution: after setting the focus to the input field, send a click event to that same input field to make it visible.
The first dialog I updated is IEPwdDlg.vbs
, other Internet Explorer based dialogs will follow soon.
While at it, I also added some code to allow pressing the Enter key instead of clicking the OK button.
October 13, 2015
has been updated: it now accepts the optional
switch for localized and/or customized button captions, and the list items can be read from a text file, besides being specified on the command line.

, a batch file to search and remove Local Shared Objects
(a.k.a. "Flash Cookies"), has been updated — way overdue!
It has been adapted to work in Windows 7 (and later) versions too.
And the updated version will also search and remove Local Shared Objects set by Google Chrome.
Use the batch file without command line arguments for verbose interactive mode.
• On some of this site's pages, the new menu was still missing. This has been corrected.

• A minor update for TranslateCulture.exe
: it now displays the descriptive name for the culture (language), besides the short code.
I used it to list the opening times of our local botanic garden in Arabic, since most of the refugees from the nearby temporary refugee camp don't speak English.
After many tries, I gave up trying to display the text correctly in Arabic in the console of my English computer.
Instead, I set the code page to 65001 (UTF-8; 1256, Arabic, may work as well in this case) and redirected the output to a file:
TranslateCulture.exe ar-SY /C /W > openinghours.txt
Notepad is perfectly capable of editing the text, adding English and Dutch text without affecting the Arabic text.
However, using the cursor in a mixed left-to-right and right-to-left document does
take some getting used to...

was updated: the minimum width is now 220 pixels (used to be 200 pixels), otherwise the default title would not fit because of the newly added icon.
To make any
title fit, you can now set the dialog window's size with the optional
Empty titles are now replaced by the default title (program name and version); to really specify an empty window title, use a doublequoted space on the command line.

• Also by request I added the option to specify an initial date/time to DateTimeBox.exe
The initial date/time can be specified as a string in yyyy-MM-dd HH:mm
format, or by specifying a file whose timestamp can be used.
