How to access the data on a dropdown list in excel using WIN32OLE in ruby

I want to programatically choose one of the options available in a Excel Dropdownlist. To manipulate the worksheet I’m using win32ole on ruby. It works well until I try to change the value of the dropdownlist.

I simply don’t know how and google has been of no help.

setting a value to a a cell is as simple as worksheet.Cells(x,y).Value=new_value. This is not choosing one of the alternatives available on the dropdownlist and it’s not even possible since the cell in question is protected.

The protection doesn’t stop me from changin the value manualy via excelso I figure there must be a method or functon somewhere that allows me to simulate this action aswell.

Help in advance for any suggestions.
