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...

Hi All,
I am trying to write a C# program to call a routine in managed C++.
In the routine, the C# program passes a delegate to the managed C++.
The delegate looks like this in c++:
public __delegate void FoundPidDelegate (
unsigned char *pData,
);
The C++ is able to call the C# because my routine in C# is unsafe and

Does anyone know how to pass a managed array to a method and have that
method actually create the array if necessary, ie., if the passed array is
null? For example:
void AddAttribute(XmlAttribute* attribList, XmlAttribute* anAttrib)
{
if (attribList == 0L) {
attribList = new XmlAttribute * ;
attribList = anAttrib;
} else {

I need to pass a pointer to 'int' as a parameter in a managed module to a
managed member function. I am assuming I need to box my value. Is this true,
or can I just pass the address of my variable ? The variable needs to
conform to CLS specifications.

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,...

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....

Hello
I'm a network technician in training and I need your help.
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.
