Hi,
Usage of FileStream ( and other stream related objects ) internally use an IO Completion port, Now, Taking that in mind, does all of the stream object of a certain process use a single IO Completion port common to all streams ( file based streams, e.g. socket, file, ... )? This could easily done with Win32 API by creating a single IO Completion port and associating it with several file based objects ( e.g. several sockets ).
Usage of a single IO Completion port for all streams of a certain process dramatically decrease the amount of context switches done...
What is the way File based Streams are implemented by the .NET Framework? do they use a single IO Completion port or a dedicated port for each stream?

You should take a look at SSCLI aka. ROTOR.
I think you could find all the information you need there.
If you are willing to search...

Suppose you have a program containing commands and file name parameters.
A simple class providing completion could first read all the commands
to list, and extend that list later using all file names in given
directory. This way a user could tab-complete (using
readline.parse_and_bind('tab: complete')) any command and any file. Eg. if
a command 'move' is implemented and there are files 'foo.txt' and
'bar.txt', the user could type

Hi,
Could you give your opinions on the best code completion in Python
IDEs. My only complaint with PythonWin has been that the code
completion support is incomplete. The interactive mode has better
behavior than the editor. Tried to fix it but could not. Boa is not
too different. At least when I last checked (a few months ago) Komodo
and Visual Python were not very different either.
Wing IDE seems converse. The editor auto list members...

Some people have suggested the desire for code completion and refined
edit-time error detection are an indication of incompetence on the part of
the programmer who wants such features. Unfortunately these ad hominem

to divert the discussion from the technical subject to a discussion of the...

Sometimes if I build the app I will get intellisense, undo, and code
completion (automatic completion of if stataments etc), but after a few
lines of code this stops.
I lose any code completion
I lose all automatic code indentation
I loose intellisense
If there are errors (squiqqly lines under the code) and I fix them, the blue
squiggly line still appears until I rebuid.
Rebuild fixes the formatting too.

Hi,
I am trying to develop an application for a touch screen using buttons
for the numeric pad with Completion ComboBoxes.
At the moment I am having a problem sending the button presses to my
Completion ComboBox using sendkey.wait. From the keyboard (that will
not exist for my final application) I can enter text into my
Completion and the selection completes as expected.

Hello folks,
I am unable to find appropriate documentation on the type promotion of bit-fields when using the generalised comparison operator "<=>".
The problem is that using the GNU compilers, it seems that the internal comparison operator "<=>" tries to promote arguments from unsigned to signed.
This is as boiled down as I can make it.
Here is my compilation command:
