I have one unmanaged and one managed class in the same vc++ project. Managed
object creates one instance of unmanaged class and needs to pass a callback
reference so that unmanaged class can periodically call the managed class's
method (without holding the reference to the managed object).
Can anybody please provide me with a short example or a basic idea?
Thanks a lot,
Sasha

Hi,
I need to make a function that can display data on my Managed C++ app and be
called by an unmanaged C++ DLL. Something like :
void Form1::Form1_Load(System::Object * sender, System::EventArgs * e)
{
MyDLLInit(MyAppDisplayFunction);
}

Hi,
I have an unmanaged application that converts a function pointer to a
delegate and then pass this as a parameter(delegate) to a managed function
which then invokes it. Currently Im able to jump to this unmanaged function,
but the values of the parameters inside this function Im seeing are not
correct(they have some garbage values).

Hi,
I have my main application class(unmanaged) that has a none static member

of this C# method is a delegate. I need to pass the none static member
function as a delegate(function pointer) as a parameter in the managed C#...

I would greatly appreciate some help on passing managed object into unmanaged

Folks,
I have a bit of a quandary I was hoping for some expert guidance on. Keep in mind I am not a C++ developer, but I have worked with the language a bit.
I have a native C++ API which I am currently wrapping in managed C++ in order to expose the API to .Net clients. So far, so good, everything is working out just fine. However, I have ventured into the callback portion of the API and I am stumped.
In the native API, the callback...

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...

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,...
