Hi all.
Handling files is an extremely frequent task in programming, so most
programming languages have an abstraction of the basic files offered by
the underlying operating system. This is indeed also true for our language
of choice, Python. Its file type allows some extraordinary convenient
access like:
for line in open("blah"):
handle_line(line)

I created an usercontrol ACTRL. and I fired an event from the ACTRL.
in my form application, do all ACTRL controls have to do "+=" to sign
up the event? my problem is if the ACTRL control in the form app
doesn't sign up the event, the application will throw exception
"Object reference not set to an instance of an object" during the run
time.

I've spent the last 3 years programming VC++, and learnt that Windows
programming is all about messages.
Now I'm doing C#, and there isn't a windows message to be seen! Now, I don't
miss those messages at all - in fact I'm very glad to see the end of them,
but I am puzzled as to where they've gone. Has .Net got rid of windows
messages, or are they just hidden inside the CLR, where windows windows (to
use the VC++ term for the real...

Hi all,
Where can I get some insight on using the __hook, __unhook, event_source and
event_receiver for specifically COM events. The documentation given in MSDN
is very minimal. I have the following scenario
Server (COM event source) is written in VC++ 6.0 using ATL (event interfaces
can be either dispinterface / IDispatch based)
Client (COM event receiver) is written in VC++ 2003 using attributed
programming and unified event handling

Hi,
I'm active in VC++ for several years now, so I know some things (I think).
Using MS-Access I store a db with lots of entries and uses the VBA
techniques to export those data to e.g. HTML, XML and other kind of data.
I'm using MS-VC++6.0-Enterprise (with sp6) at NT4-Workstation (sp6a) and
MS-Access97 (from MS-Office97). Reason that I won't upgrade to latest
Office/VisualStudio is that I must ensure that any application I develop

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:
g++-12 -std=c++20 -Wnarrowing bit_field.cpp
Here is the code in...

Overview:
Windows 11 and 10 have less user interface control over operating system update behaviour than previous versions of Windows. In Windows 11 and 10, there is no way to turn off the Windows Update option using the Control Panel or Settings app; it automatically checks for updates and installs any it finds, whether you like it or not. For most users, this new feature is actually very convenient. If you want to control the update process,...
