Hi,
I get this error
error C3181: invalid operand for __typeof, expected a fully defined managed type
Whenever I try to use Enum in VC++ .NET, which is actually defined in my VC++ library (unmanaged code)
Is there any way so that I can perfom "Enum::GetName" on the Enum of unmanaged code?
Please suggest

Hi,
In the managed C++ class below I get compile warning C4677
from VS2003. "signature of non-private function contains
assembly private type", even though the managed enum is
public. I have to drop the "enum" keyword from my member
variable declaration to keep the compiler happy.
Shouldn't I technically be able to use the "enum" keyword
without a warning?

Is there any way to port legacy C++ enum to managed object?
For example, let's assume there is a C++ header file(we cannot modify it,
because it is updated by other vendor). It has a enum definition like this.
enum AAA { a,b,c };
Assuming that we made a managed DLL whose namespace id MyLib. I tried
several way such as
typedef __gc AAA MyAAA;

I've been instructed to work againt a huge unmanaged C++ API from a C#
application.
Now, the only way, as I've understood it, is to go the Managed Extensions
for C++ way. This means I have to write a wrapper between unmanaged API and
my managed app.
Now on to the question:

Forgive me if my post seems a little amateurish...
I'm requesting assistance from some of you smart folks out there to
get the managed calls write that meet the specification in the esa.h
for Esa_Init. When I make a call, VS2005 reports
"AccessViolationException" and refers to the 4th parameter
(EsaT_State_Handle). I don't know how to define nor pass this
reference correctly to the legacy DLL. What am I doing wrong? Thanks

Hi everyone,
We have a c++ server application that we are writing a GUI client
application for. To save our time and to avoid duplicating all the code and
functionality that already exists in c++ classes I am building a managed c++
assembly around these classes so that a c# program can use them.
The problem is that alot of these c++ classes use enums, I would like to
make these visible to the c# application but I cannot find a way to...

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,...
