boolean values in COM / VB / Python

[John J. Lee]

ie.Document.execCommand("SaveAs", false, pathname)

where ie is an Internet Explorer object, pops up a dialogue box, no matter
what value for false I try, from (1==0, 0, "0", None). According to the MS
docs at

http://msdn.microsoft.com/workshop/author/dhtml/reference/constants/saveas.asp

and

http://msdn.microsoft.com/workshop/author/dhtml/reference/methods/execCommand.asp

this isn't supposed to happen, because when the second argument to
execCommand is 'false', the command 'Does not display a user interface'.
According to Mark Hammond just last month, 0 should do fine as a way of
representing 'false':

Any clues as to what is happening?

Tips on the differences between C++ / VB and Python in general would also
be appreciated -- presumably there must be some reliable and mechanical
way of doing this?
