Hi, first let me say many thanks for keeping the old McMillan installer
going. I used to use it for my program (fullmeasure.co.uk/powertalk) but
after hitting a problem with a release of win32all and finding McMillan
gone I switched to py2exe but have now hit problems with that. Anyone
know how Gordan is?
Right my problem: I have a COM client that needs to use the early
binding gen_py modules and so uses gencache.EnsureDispatch() rather that
the usual Dispatch() which falls back to Dynamic/late binding. This is
mainly coz Mark Hammond told me to :-| (I use COM constants and event
sinks).
The problem is that the modules are NOT found in the pyinstaller gen_py
folder. This is actually hidden on a dev machine as it picks them up
from the lib\win32com or %temp% gen_py folders so you have to delete
them first to show the problem. This then repros the target machine
setup where the users doesn't have a python distro installed. This all
works fine when using Dispatch().
I've gone rather code blind so could do with some help. I'm guessing it
needs a hook but don't understand quite what/how they work. It seems
EnsureDispatch() is not used much and exercises the code differently so
there are perhaps problems in the win32com.gencache code.
OK this minimal code, which should work on any XP box, shows the problem
from win32com.client.gencache import EnsureDispatch
v = EnsureDispatch("Sapi.SpVoice") # Dispatch() is fine
v.Speak( "Hello.")
built with:
makespec.py --onedir PITest.pyw
Traceback (most recent call last):

I initially thought it was the fact that the _GetModule() looks for
win32com.gen_py.<CLSID> and that is not the path under the pyInstaller
created 'support' folder but it seems to work OK for Dispatch(), I guess
via these mysterious hooks.
BTW the fact that pyInstaller uses it's own gen_py folder is better than
py2exe as it reduces interactions with the python installation or user
copies causing differences between dev and target machines.
