I encountered the error of Unknown OLE server: `AutoItX3.Control’ , following is the solotion:
navigate to the folder of \ruby\lib\ruby\gems\1.8\gems\watir-1.6.2\lib\watir, and type regsvr32 AutoItX3.dll
we can login to a drupal site by http://www.example.com/?q=user when the login block has been hidden.
I faced a weird problem.
I can start a test job test.rb by WindowsXP task scheduler, but cannot initiate the test job by Windows Vista task scheduler, the test.rb can be run by double click on Windows Vista Explorer.
I encoutered a solution for this when I almost went to install windows xp on my computer, just Disable User Access Control on the Control Panel of Vista, and everything is ok.
