OK, so I've gotten into a philosophical disagreement with my colleague at
work. He is a proponent of the Template Method pattern, i.e.:
class foo
{
public:
void bar() { do_bar(); }
protected:
virtual void do_bar() {}
};

Hello
I am using asynchronous delegates to make a call to a COM ActiveX object, but even though the call occurs on a separate thread, my UI is still blocking.
If i put the thread to sleep in my delegate call, the application is well behaved (no UI freeze), but the call to the com object causes the UI to lock up
Do I have to manage calls to an ActiveX object differently than using the BeginInvoke and a callback
A sample of the code I...

Hi,
I have an application that allows functionality extension by third party
DLL's. All the specs for building these DLL's are targeted to c++, with
demo.h files containing "extern" statements, etc.
However not really knowing c++ I would rather use C#. Could you point me to
documentation/information on how to use this c++ information to properly
construct my C# routine to connect properly?

Hello,
following problem: At program end or release an assembly a serial device
should get a final exit sequence. How can I do this?
With Dispose() it's no problem, but this assembly is used in a com
interop dll and it must be guaranteed, that the final sequence is send
to the serial device, when the calling application dont send Close() or
Dispose().

actually simulate a drawing.
Basically my control is called the first time to calculate the height of
an Item (MeasureItem) and...

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,...
