Re: [python-win32] VT_UI1 ByRef behavior
Alrighty, I'll keep looking in to it. I think it is easy to make the buffers get returned as a python list. Almost all the code exists to help with that. The tough part is telling the COM that the array being passed IN needs to become a Safe Array where the size of each element is only VT_UI1. The buffer is a great thing for that and at first glance the only thing I can think of would be to modify PyCom_VariantFromPyObject to check the size of the number to see if it will fit in VT_UI1 (it is already doing this for ints and longs)...but i think that would be way to dangerous... I might still look into a proposal for changing the output, but for the input, I can't think of how to do it any other way than what you already have. Perhaps I will just have to write a script that searches my generated file from makepy and creates a layer in the python code...instead of on the C side...oh well... -Kevin On 4/29/07, Mark Hammond <[EMAIL PROTECTED]> wrote: > I was curious is there a way to prevent an array of VT_UI1's from being > converted to a buffer?

I have a COM object that is doing an upload. I want a system tray icon that: 1) Shows a heartbeat (upload progress indicator) 2) Provides the user with a way to cancel the upload I found systrayicon.py and it almost does what I want. I thought about using socket server/client to have the two apps communicate but I'm at a complete loss as to how to implement socket client in the systrayicon.py program since it uses PumpMessages. I just don't see how to connect to my com server (which would also be a socket server) inside some loop mechanism. Thanks in advance for any assistance.

Since I assume you're not looking for cross-platform portability here, I'd be inclined to use one of Windows' built-in mechanisms: Events, Pipes, Messages etc. They should mesh with a suitable message loop, eg: http://aspn.activestate.com/ASPN/Cookbook/Python/Recipe/82236 TJG ___ Python-win32 mailing list Python-win32@python.org http://mail.python.org/mailman/listinfo/python-win32

You set the sockets to non-blocking, and use WSAAsyncSelect to get messages posted to the messageloop when something interesting happens to the socket. I do not know if pywin32 exposes WSAAsyncSelect, otherwise you can use ctypes to call it.

[python-win32] GetOpenFileNameW & InitialDir
Hi! I'have a problem with this code : import win32gui fname=win32gui.GetOpenFileNameW(InitialDir="C:\\dev")[0] print fname The InitialDir is not set. It's already the last dir opened, and not my request. Any idea ? Thanks by advance.

It would need to be like any other pywin32 COM object; you should be able to find info about that on the web.

Forgive my ignorance but those are my first steps with com. Does that mean I should create and register a COM server? Basically I'm trying to reimplement the following code in python: http://www.codeproject.com/internet/CMapiEx.asp Up to now this was straightforward, but at this point I'm stuck.

I can't see anything related to a "sink" on that page - but as a start, consider looking at the spambayes package at spambayes.org - there is code there that deals with MAPI in various ways.

True, I was refering to the code in the zip file on that page. I'll
attach MAPISink.h below.

Thank you. I'll have a look at it.
