I am trying to wrap a native-C++ DLL in managed C++, to
use in a .NET project.
The native code is compiled into a DLL, and I have created
a .def file that exports the mangled names of the symbols
I am going to use from the wrapper library.
The wrapper library has the code written that uses the
native classes, and wraps them to present an equivalent of
their interface for .NET.

Dear VS Team,
using the Beta 2 of VS 2005 I've encontered the following problem.
Let's assume threre are three Dll's, one unmanaged and two managed. In the
unmanaged we put a simple unmanged struct "A" which is exported in the usual
way.
The first managed assembly defines a managed class "B" using the unmanaged
class "A" defined in the unmanaged Dll. This class "B" has got a public

What do you make of this? I cannot tell for sure but it almost seems as
the the transition thunk to get back from the native bool method to the managed
caller is looking at eax and, if any bit is set, normalizing it to 0x00000001.
If it wants to normalize the value then it should only operate on the al
register since that's all that the native bool method uses to hold the return
value.
Is this a known VC 7.1 bug? Is there a hotfix...

I am doing my own PrintDialog, and have placed there a combo with the
printer names, as in the PrintDialog provided by VB.NET.
Here is the question: how do I open the native windows printer dialog
for the current printer, so that my current
PrintDocument.PrinterSettings will be set according to the User choices
?
Thanks

Hello
I don't have C++/CLI 2.0 reference handy and the code below was written
after long hours of research and shallow readings. From what I see, the code
works and looks logical to me. Can you please review it and tell me if I
overlooked something.
On the other hand, can you suggest a good C++/CLI 2.0 book for starters?

Hello,
I want to give multiple native classes (in different mixed mode dlls) access
to a managed output window (for error messages). Therefore I wrote a native
singleton with __declspec (dllexport). I get the following compiler errors:
Error 224 error C3389: __declspec(dllexport) cannot be used with /clr:pure
or /clr:safe
Error 225 error C4394: 'ErrorHandler::instance' : per-appdomain symbol

Hi, dear all,
I want to wrapper the legacy C++ Template Class to be used by the C#
code, so I try to wrapper the legacy C++ code into CLI/C++ code first.
One problem is how to wrapper C++ template class, such as List, Queue,
etc?
Here is a snippet of Native Code:

I'm seeing incorrect (I think) behavior in the event of an exception
thrown in a native C++ library. Basically, the stack appears to
unwind correctly if the caller is native, but incorrectly if the
caller is /clr. Consider the following C++ static lib:
// ehTestLib.h
#include <iostream>
class worker {
public:
~worker() { std::cerr << "~worker()\n"; }

Hi all,
We have a native class modeled after the System::Exception class, and all
exceptions that we throw derive from this class. For now this class is
quite simple: just Description and InnerException public members. One of
these days I'll dig into how to implement a StackTrace property (I assume
that this is possible using something like dbghelp.dll, but I've never had
the time to look into it).
I've recently written a managed...

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:

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,...
