Hi, there.
Recently I was working on a problem where we want to save generic
closures in a data structure (a vector). The closure should work for
any data type and any method with pre-defined signature.
When developing this lib, I figured that the
pointer-to-member-function, although seemingly an attractive solution,
does not work well for us.

When I write:
int a;
and I want another name for "int", I can simply write
typedef int interger
but what if I want a more descriptive name for the datatype
int a; ?
typedef int two_intergers of course won't work.
Thanks.

Hi,
I'm not sure that if this is the right forum, but any help would be greatly
appreciated.
I am porting some java serialization code to c# and I can't figure out the
correct way to do it. It seems that either I can use default serialization
or implement ISerializable. Is there any way to do both (e.g. extend the
default serialization). In other words, I want to be able to implement my
custom serialization code but call the...

I have an object marked with <Serializable()and using an xmlserializer to
save xml to disk.
But I need the XML to include the datatype of the property. I tried using
<Xml.Serialization.XmlElement(Type:=GetType(Double))but that won't embed
"double" in the XML-file. How can I get the dataype in the xml-file?
Thanks

Hi all,
I have the need to generate C# classes from XSD schemas, and the XSD.exe
tool is just (almost) great for that. I said "almost" because it seems that
every XML Schema datatype other than boolean is rendered as a String
field/property.
As an example, I am getting:

Hello,
I hope this is the right place to post a question on Boost. If not,
please let me know where I can post this message and I will do so.
I am having a strange problem with std::string as I am trying to read

it is possible that I have not understood the usage. In the code

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,...
