Hi all,
I am writing a component that exposes a C++ library as a .NET
component. The approach is somewhat automatic: every library C++ class
has its managed C++ counterpart that keeps a pointer to the unmanaged
class instance.
As usually in such a scenario, the IDisposable/Dispose()/Dispose(bool)
pattern should be used. The problem is that in my approach it is often
impractical, as the library's unmanaged objects are quite small and

Hello,
My question is how to use C# to call the existing libraries containing
unmanaged C++ classes directly, but not use C# or managed C++ wrappers
unmanaged C++ classes?
Does anyone know how to do that?
Thanks.

Hi,
(Initial info: .Net 2003 on Win2000)
I'm developing a .Net App that uses a dll (say, dll_1)
created in VC6 and _successfully_ recompiled in .Net 2003
(unmanaged, no wrappers). The dll_1 is set as a dependency
in the application project properties (Linker->Input-
>Additional Dependencies).

Hello,
in the last few days I've made my first few attempts at creating mixed
C++ managed-unmanaged assemblies and looking afterwards with ILDASM
at what is visible in those assemblies from a managed point-of-view
I've noticed that:
1) for each managed and unmanaged C function (not C++ classes) I get a
public managed static method (defined on a 'Global Functions' class)
in the generated assembly with an export name of the form

Hi,
my company is going to migrate a large VC++ application to .NET to
make use of Windows Forms (the old class library is not updated any
more). We are not planning to migrate the rest of the code which works
well.
I understand the basic concept: our code is unmanaged, Windows Forms
is Managed and Unmanaged may not call Managed code. I read about
Wrappers, PInvoke, Runtime Callable Wrappers for COM and about It just

Hello All,
we are doing a quite a big project that contains at
the lowest level an unmenaged c++ classes. Above it there
are managed wrappers and at the top there are ASP.NET
pages. Can anyone tell me how to force ASP.NET not
to "clear" or reinitialize unmenaged global or static
variables that are set on unmanaged level between
successive requests?

Hi,
I am faced with the following common managed/unmanaged C++ interop
problem:
- I have a .NET form that acts as a front end GUI to a processing
engine in the background. The processing engine runs as a thread that
is managed by the front-end form class.
- The processing engine must have a callback mechanism to update the
form about progress, and to send status messages that will be displayed

Hello.
I'm new to .NET, and I'm trying to implement a callback function. I want my managed C++ code to call an unmanaged function, passing in a callback function that the unmanaged C/C++ code will call.

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:
