How to open a file with win32ole

Hi all,

I want to open a file via win32ole. I find the method 'Open' there but
always get error feedback. I wonder if anyone can give me a hand.

Thanks,

Li

try this:

require 'win32ole'
fs=WIN32OLE.new('SAPI.SpFileStream')

p fs.ole_method("open").params

file='c:/test.txt'

fs.Open(file,2) #least two params
fs.write("data")
fs.Close

Hi bud,

Thank you very much for the tips. It is so sweet.

From this example I guess that if a method is on the list but the object
cannot receive it, most likely that more parameters need to be passed
in.

One more question: How am I supposed that I should pass number 2 in the
script above, instead of other numbers like, 0, 1, 10,...?
