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

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,…?
