Wouldn't it be the case that you failed to specify that the stream is
for input?  By passing ios::nocreate, you overrode the default
argument that is ios::input (sp?), so you should have ORed
ios::nocreate to ios::input to get an input stream.  Yes, it's
counter-intuitive, but that's the way it is implemented.
