Could some C guru help me please? A byte is an unsigned char in C.
How do I convert from a C string to a corresponding byte array. Any
help would be greatly appreciated.

hello,
I'm allocating a byte-Array in C# with byte byteArray = new byte;
Now I want to pass this byte-Array to a managed C++-function by reference,
so that I'm able to change the content of the byteArray and afterwards see
the changes in C#.
(if you wanna know more details: the goal is to write the content of an
existing char-array in c++ precisely into the passed byteArray, so that
after the function has proceded the content of the...

I have a managed DLL that I've used to expose a C++ class. One of the
functions in this class reads a line out of a file into a buffer of type
"unsigned char*". Since all the data is just straight byte data (that is,
I'm concerned with individual bits packed into the bytes), I'd like to put
that data into a byte array that's passed from the C# app to the DLL
function.
In the past, I've been able to marshal strings to character strings...

Hello, all.
I've created a C# dll that contains, among other things, two functions
dealing with byte arrays. The first is a function that returns a byte
array, and the other is intended to receive a byte array as one of its
parameters. The project is marked for COM interop, and that all
proceeds normally.
When I reference the type library in the VB6 project, and write the
code to call the function that returns the byte array, it works

This is the code snippet that I've come up to convert a byte
to string. Is there a best practiced method for such a conversion?

public static string ByteArrayToString(byte array)
{
if (null == array || 0 == array.Length)

Trying to convert string to byte array.
the following code returns byte array of {107, 62, 194, 139, 64}
how can I convert this string to a byte array of {107, 62, 139, 65}
System.Text.UTF8Encoding str = new System.Text.UTF8Encoding();
string s = new string((char)107, 1);
s += new string((char)62, 1);

Hi,
This is a question about declaring a signed 8bit numeric type in C++ that prints like a numeric variable and not like a char variable. I would like to declare a type with name 'byte' which represents 8bit numeric values. Of course C++ has char with the right size. So I tried
------
typedef char byte;
------
This is fine, until I tried
---------
byte b = 1;
cout << b;

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...

I am currently learning how to create and manage the different types of VPNs and I have a question about LAN-to-LAN VPNs.
The last exercise I practiced was to create a LAN-to-LAN VPN between two Pfsense firewalls, by using IPSEC protocols.
I succeeded, with both firewalls in the same network. But I'm wondering if it's possible to do the same thing, with 2 Pfsense firewalls...
