Hi,
I'm trying to migrate native c++ class to managed c++
class.
The native class header definition looks as:

I am converting a multithreaded MFC application to Managed C++ under
VS2003 that uses a DLL that was compiled in Microsoft Visual Fortran 6.
The main function of the fortran DLL (FVIS2FOR) takes a pointer to a
function (UpdateVC) that updates a status window periodically. I am
using a delegate to attempt to accomplish the same thing in .NET, but
it doesn't quite work. The DLL will call the function and the function
appears to act...

Newbie question here. I have a VS.NET 2003 MC++ (not C++/cli) project

Hi all,
I'm having difficulties passing data back to managed class from my
native class when the data is generated from within a native thread in
the native class itself. I will give the following runtime error,
" Attempting to call into managed code without transitioning out first.
Do not attempt to run managed code inside low-level native
extensibility points, such as the vectored exception handler, since
doing so can cause corruption...

Hello and thank you in advance for your help.
Can anyone think of a reason why this code would work properly on one PC,
but not another?
I've got a System.Windows.Forms.UserControl that products events which I
want to consume (sink) within Internet Explorer.
I'm following the instructions at:

Hey!
I have a managed c++ app (actually, the app is mixed managed/unmanaged, but
this happens in the managed part) that dynamically generates some program in
c# (with CSharpCodeProvider).
The problem now is that somehow I get runtime errors when trying to pass a
function (via delegates) into the c# code in order to make c# call back that
function. The message box says: "An unhandled exeption of type
'System.ArgumentException' occurred...

We are writing a wrapper in Managed C++. Wrapper is based on a C dll.
That wrapper will be used from .Net based application and VB also.
Our initial understanding that a .NET Application developer will pass
a delegate to the Managed C++ wrapper and in this wrapper, we have to
cast the delegate into function pointer. The argument list of that
function pointer is not compatible in .NET.
A .NET developer will pass a delegate to get the...

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

I need to pass a reference (address of) of a managed class into unmanaged

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...

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.

I am currently learning how to create and manage the different types of VPNs and I have a question about LAN-to-LAN VPNs.
