hi all,
i've got a class that takes a parameterless function pointer as a parameter.
i want to store that function pointer in a variable and i'm trying to figure
out the syntax. i came up with the stuff below, but it's telling me it can't
convert from void *(void) to void(void), which i didn't think i was doing.
what's the proper syntax for defining and initializing a function pointer
like this?
thnks a bunch,

Hi,
I'm having a problem with a return statement being parsed to return a
function (I think). Check here:
template <typename T> class A {};
template <typename T> class maker_of_A {
public:
A<T>& make_A() {return A<T>();};
};

The syntax for a public variable seems to be "Public Shared name As type". How AND where do I put these in my AppMain (startup module) so the can be used by two different forms
Thanks

I found a bug??? with constants in csharp. Consider the following:
internal static readonly int MAX_BUFFER_SIZE=8192;
internal static readonly int
MAX_MESSAGE_LENGTH=MAX_BUFFER_SIZE-USER_DATA_OFFSET;
internal static readonly int USER_DATA_OFFSET=29;
When the constant MAX_MESSAGE_LENGTH is calculated the USER_DATA_OFFSET

Hi, All:
I read the following passage from a book:
"There are three exceptions to the rule that headers should not contain
definitions: classes, const objects whose value is known at compile
time, and inline functions are all defined in headers. "
Can someone explain to me why some of the const objects must be defined
in the header file?

There is already one function processing pointer values this way. And
there may easily appear more, including wrappers for this function.
For purposes of further discussion, consider simplified function,
`consume'. It has one arg, INBUF, that points to a variable that
points to the first character in the input buffer. The function never
modifies characters pointed to by `*INBUF'. It, however, updates
the `*INBUF' value to point to...

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,...

With the development of smart home technology, a variety of wireless communication protocols have appeared on the market, such as Zigbee, Z-Wave, Wi-Fi, Bluetooth, etc. Each protocol has its own unique characteristics and advantages, but as a user who is planning to build a smart home system, I am a bit confused by the choice of these technologies. I'm particularly interested in Zigbee because I've heard it does some...

Let's talk about the concept of autonomous AI software engineers and no-code agents. These AIs are designed to manage the entire lifecycle of a software development project—planning, coding, testing, and deployment—without human intervention. Imagine an AI that can take a project description, break it down, write the code, debug it, and then launch it, all on its own....
Now, this would greatly impact the work of software developers. The idea...
