What if I have some special constructors and do not have a default
constructor. It seems to be very useful when I do not want to forget to
initialize some fields properly. As I have understood classes with no
default constructor can not be arguments of generic types. Why I can not
specify "new ( smth. )" as a constraint of a generic parameter? Or may be
the document http://www.msdn.microsoft.com/vcsharp/language misses this
case?

I have a class SwatchPanel which takes Swatch as a parameter type. How can I call a static function within the Swatch class?
For example the code below fails on TSwatch.Exists. How can I get the call to work?
Exists is a method within the Swatch class NOT the SwatchPanel class.
Is this possible?
Suggestions would be very welcome.

I have the following template to ensure that a given number (val) falls into
a range (between vmin & vmax):

T retVal = val;
if ( retVal < vmin )
retVal = vmin;

I apologize if this question has been asked before, but after about
half an hour of searching I haven't been able to find an answer online.
My code is beloiw, with comments pertaining to my question
In short my question is why when I pass a generic type directly to the
formatObject function it works fine, but when I pass it to the
checkText function where it is itself a generic argument, and then it
is passed to formatObject, it is seen...

Is that not allowed to assume generic type numeric type? As far as I've
tried, I got an error with the following code:
public class AAA<T>
{
public int Foo(T a)
{
return a; // error: Cannot implicitly convert type 'T' to 'int'
}
}

How can I use reflection (or some other method) to find the type of an
object that has been passed in to my method under an interface definition?
I try to use GetType, but that won't work.

in a generic class, can I code the class so that I can call a static
method of the generic class T?
In the ConvertFrom method of the generic TypeConvert class I want to
write, I have a call to the static Parse method of the conversion
class.
if (InValue is string)
return T.Parse((string)InValue);
else
return base.ConvertFrom(context, culture, InValue);

Is it possible to pass a generic parameter of the same class to to its
constructor, where the "T" type passed in the constructor is different
than the "T" type of the instanced class?
ie,
public class SomeList<T>
{
public SomeList(SomeList<TthisSomeList)

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...
