If you use perl on Windows, you've probably got at least one script that you'd like to be able to put on your Desktop and drag-and-drop files onto to perform some function on the dropped files. There are at least two ways to accomplish this.

1. If you've installed Active State Perl, every perl script with the ".pl" file extension on your system is associated with perl. You can make every one of these perl scripts a drop target by creating a Drop Handler as follows: Create a new registry key "shellex" under the "HKEY_CLASSES_ROOT -> Perl" key with a default value of {86C86720-42A0-1069-A2E8-08002B30309D}. You can do this manually, or save and run this .REG file to modify your registry automatically.
   • Note, however, that the filenames passed to your script by this method will be DOS 8.3 filenames, not long Windows filenames.

2. Alternatively (or in addition), you could create a shortcut to Perl and add the path to the perl script as an argument, e.g., in the "Target" field of the shortcut properties, type "C:\Perl\bin\perl.exe" "\PATH_TO_YOURSCRIPT\YOURSCRIPT.pl". The shortcut will automatically be a drop target whether or not you implemented the registry change above. (You could also create a shortcut to wperl.exe, rather than perl.exe, and eliminate the DOS box.)

Here's a perl script I wrote to automate Whoo and Graham's suggestion: hidehtsrv.pl. I suggest creating a cron job to run hidehtsrv.pl periodically. Note: this script requires another of my perl scripts, randpass.pl, a pseudo-random string generator.

Here's a b2evolution forum thread about trackback spam, and here's a b2evolution forum thread about why renaming is effective.
