• As far as I can see you are running Windows 7, right?
• Take a look into your foobar2000 -> preferences -> components. Does 'COM Automation Server 07 alpha 6' is listet as component?
• Have you tried to run the script when foobar2000 is running? I've had the problem, that foobar2000 did not start automatically on script execution.
• Some anti-malware software could block the COM Server. Check your log-files there if so.
• You could try to reinstall COMserver with administrative privilleges (right-click setup-exe -> run as administrator).
• Next thing to try: Register the server manually with the command line 'foobar2000.exe /regsvr:comserver2'

• As far as I can see you are running Windows 7, right?
  Right
• Take a look into your foobar2000 -> preferences -> components. Does 'COM Automation Server 07 alpha 6' is listet as component?
  Yes - exactly
• Have you tried to run the script when foobar2000 is running? I've had the problem, that foobar2000 did not start automatically on script execution.
  This is how I understood your tutorial - have foobar2000 running first then start the script - yes!
• Some anti-malware software could block the COM Server. Check your log-files there if so.
  Running security essential only, do not see anything in the logs
• You could try to reinstall COMserver with administrative privilleges (right-click setup-exe -> run as administrator).
  Yes - deinstalled and re-installed COM server with admin rights
• Next thing to try: Register the server manually with the command line 'foobar2000.exe /regsvr:comserver2'
  Yes - tried it

Hey Kluch!
Thanks a lot for requesting a GUI. As I have already written in the FoobarSync Wiki, I would appreciate if anyone is willing to develop a GUI for my script!

I will focus my spare time on developing the pending changes and some functional feature requests from future posts here. Reason is, that I've litte exerience in Visual Studio and other GUI-orientated develop environments.
I'm the command line / scripting oriented guy. I love to fullfill my personal - some times very special - needs in that way. My approach for FoobarSync was, that I wanted to have an target-individual synchronization, that can easily be triggert by any other application like schedulers or event handlers like 'USB-Device connected'. With the current release my personal needs are fullfilled. Because coding is a hobby, I will keep on tweaking and expanding functionallity.

The way I designed the script offers much opportunities to use it, also in foobar2000s' GUI.
Example: Use components ColumnsUI plus Run Command and simply add a button in foobar2000, that you can click to start sync to a connected device. Need support for this or other configurations? All it needs is to ask here for the way, how to solve a needed feature. I am sure, that forum readers will share their experience then. And if I (or someone) thinks the solution useful, this person may add a tutorial or similar to the Wiki. If it's a functional extension, it may take me just a few minutes to implement it. And I will do so, if I find it useful.

So keep on asking questions! 

• renamed MaxTitles to MaxItemsOnTarget
• renamed MinSpace with ReserveFreeSpace
• implemented ignore as new option in SyncRules (paramter 3)
• match between SyncRules and ConvertFormats now is case insensitive.
• new Queue-file for FilesOK to support future detailed reports
• fixed 'ERROR:RemoveOphanedFiles:File ...'
• added some basic plausibility checks for configuration file sections
• improved overall error trapping and handling of warnings

After poking around, I realized that I didn't have the proper permissions to read/write to my iPod and that it didn't like certain playlist names. I only figured this out by poking around the code and printing out stuff to the console. Is it possible to implement error messages? Or did I somehow miss something in the documentation that covers these issues? Many apologies if that is the case.

• debug-level for console output is controled with command line option debuglev.
• playlist selection is controled per configuration file with PLselectRegEx
  to see which playlists match / do not match PLselectRegEx, you can use the Console Prompt
  ('ENTER=Continue  S=STOP!  C=Console')
  It may be helpful to use a online regex-tester when playing around with PLselectRegEx

Also, I'm not an expert when it comes to tagging so sorry for my ignorance. I have a lot of Arabic, Korean, Mandarin, and Japanese songs. After syncing, a lot of the files names don't show any foreign characters at all. How do I know if the files are tagged/named using Unicode and how do I make sure it's in Unicode?

• The allowed character set for folder- and filenames is controled with WhiteListChrs.
  But I don't know how to allow arabic unicode characters here.
  Again a online regex-tester could help to to find out correct settings.
• If items in your playlists are missing or do not play:
  The encoding INSIDE your m3u-files is controled with PLfileFormat.

• minor bug fixed: nopause caused script so pause endless
• Flagfiles for conversion control have moved from c:\ to folder where sync.vbs is executed
• ffprobe.log has moved from c:\ to folder where sync.vbs is executed
  (used if parameter #5 of ConvertFormats has value '?')

The changes you asked for are done in a the new release:

• minor bug fixed: nopause caused script so pause endless
• Flagfiles for conversion control have moved from c:\ to folder where sync.vbs is executed
• ffprobe.log has moved from c:\ to folder where sync.vbs is executed
  (used if parameter #5 of ConvertFormats has value '?')

I pass the following command line and it still processes the playlists. Am I missing something?

cscript sync.vbs task=mt runid="G:\"
