I am trying to write a wrapper class, which can store any data type to
wrap it into a class. My compiler is gcc (for c++) version 3.3.1 on a
SuSE Linux 9.0 system.
I start with the following code:
template <typename T>
class Wrapper {
public:
Wrapper(T avalue);
private:
int value;

Hi Guys,
I am trying to access a class in an unmanaged dll. I have
created a wrapper managed class to access the functions I need but no matter
what I try from the MSDN samples I can not get it to work with my code. I
have a VB Net front end which need the access the unmanaged functions. The
wrapper I wrote can be accessed but the wrapper will not compile when I
refer to the unmanaged class. I have tried using header file for definitions...

Background:
I am creating a VC++ .NET wrapper for a C++ DLL; the aim is to use this wrapper in C# as shown below:
Range r = new Range( 2, 2 );
r = new Cell( “Hello Mum” );
Range is a managed wrapper around an unmanaged range class. Vector is a managed wrapper around an unmanaged vector class. Cell is a managed wrapper around an unmanaged cell class.
Here r returns a managed Vector* and r accesses a particular Cell in the Vector.

I have a simple Managed C++ wrapper built around an *existing* C++
interactive
application. I can access the Managed C++ application classes
from a VB .NET or C# client and the GUI part works as expected. I am
using VS .NET 2002 (.NET framework v1.0.3705) for building my Managed
C++ application on a Windows XP Professional (version 2002) SP1.
I do not have much of a choice with the way the C++ program is
designed (e.g how it displays...

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
code.
I need to pass a reference (address of) of a managed class into unmanaged
code (written by a thrid party). The 3rd party unmanaged DLL will pass this
reference into standard Win32 unmanaged static callback function in my code.
Inside this unmanaged callback function I need to cast this unmnaged pointer
that I have received from 3rd party back into the...

I am having problem to delete a Managed C++ DLL that was used in a
pure C# DLL even in the following scenario.
1. Launch the application. This applicatio has its own default
applicaiton domain.
2. Create a new Application Domain.
3. Load the Pure C# DLL in the new applicaiton domain. This C# DLL uses
managed C++ DLL.
4. Create a Proxy object using CreateInstanceAndUnwrap for the wrapper

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,...
