Hi,
I have a problem with calling a managed C++ function from C#.
The function in C++ looks like Class::Func(char* Text)
this function is compiled to an DLL and this DLL is referenced in my
C# project and I can see that I could call this function like
Func(sbyte* ).

Under VC7.1, I am trying to wrap a native-C++ DLL that contains C++
objects in a Managed-C++ class library for use in a C# project.
I created and compiled the native DLL under VC7.1 as a Win32 DLL C++
(unmanaged) project. I found the decorated names of the symbols I
wanted to export and created a .def file, so that it generated an
import library.
I took this import library and had my Managed-C++ class library link
against it. The...

The following code is from a solution with a C++ project and a C# project.
The C++ project creates a managed array and the C# project tries to use it.
But I am having a 'System.ValueType' to 'System.Drawing.Point'
conversion problem in the C# project. How is this supposed to be done?

I have imported a legacy C++ project into a VisualStudio.NET 2003 solution.
I have some new C# projects in the solution as well. I am using the managed
extensions in my C++ project so that I can use the managed C# objects within
my C++ project. Here's the problem: I am getting a debug assertion in
cmdtarg.cpp (line 48) of my main CWinApp derived class when I exit the
application:

Hi,
I am writing a performence critical application, this require me to stick to unmanaged C++ as performance is much better using unmanaged C++ ( about 33% better ), Still, I am trying to avoid the usage of old style COM, my alternative is to expose my unmanaged interface through the CLI, to achieve that I have created a mixed mode DLL in which my unmanaged class are defined.
When referencing the DLL just described in another mixed mode EXE...

I am stuck in a situation and I do believe that this should work, but it
doesn't.
I have a unmanaged dll, that uses MFC. This works great.
Now I recompile the unmanaged dll so it contains mixed mode
managed/unmanaged code, but only use unmanaged code, but this gives a error
the moment I want to display a MFC dialog box: Something like unreferenced
object,... during runtime.

I have defined a managed class ( __gc ) and a unmanaged ( __nogc ) in a
separate files (but in the same vc++ dotnet project). I have no problem of
referencing the unmanaged class from the menaged one. My problem is that I
cannot reference managed class from the unmanaged.
In my unmanaged class, if I use "using namespace ManagedNamespace;" I get

I have the following situation:
There are two dlls in question: a c++ dll (native) and a c++/cli dll
(managed) with /clr option enabled.
Managed dll links with native dll.
Native dll exports a class ClientSession with a method GetJob.
Managed dll references this method and compiles just fine.

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

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:

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.
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...
