win32api exception names?

[G. Willoughby]

could you please explain the code needed a little better? sorry!

if i use something like this:

except win32api.api_error, info:
    win32api.MessageBox(0,"File can not be opened, right double click to
open\nthe file's directory.", appName, 0, 0)

then i get: AttributeError: 'win32api' module has no attribute 'api_error'

any ideas?
