Ruby win32ole - how to pass a VARIANT parameter?

Question

I am trying to automate the Windows Task Scheduler using Ruby.

I am using Ruby 1.8 under Windows Vista.

The RegisterTaskDefintion method of the TaskFolder object takes two VARIANT parameters for the username and password. Any attempt to pass a string into these parameters results in a 'method_missing' exception:

This does not work:

rootFolder.RegisterTaskDefinition("Task", newTask, TASK_CREATE_OR_UPDATE, 'user', 'password', TASK_LOGON_PASSWORD,  nil)

This works:

rootFolder.RegisterTaskDefinition("Task", newTask, TASK_CREATE_OR_UPDATE, '', '', TASK_LOGON_NONE,  nil)

Any ideas?

Just create a VARIANT?

WIN32OLE_VARIANT.new("Blah", VT_BSTR)

This is available in Ruby 1.9, but not Ruby 1.8. I was hoping to find a !.8 solution. – bvanderw Feb 19 '09 at 18:57
