Greetings!
Some classes that once compiled without problems on VS 2003 have now
problems on VS 2005 Beta 1. I'm talking about a __nogc class that is
exported with __declspec(dllexport).
The compiler message is this:
VCSelectLibraryForm.cpp
...\Forms\QiForm.h(48) : error C3395: 'TQiForm::GetDotNetMouseButton' :

I've gotten my application to compile under '/clr'. I then tried '/clr pure'
and it compiled immedately with no changes. What should I consider when
deciding which of these two option to compile under? Are there advantages
and disadvantages to one over the other?
I also tried compiling it using the '/clr safe' option and got 6420 errors
(no, that's not the error number, that's the number of errors). So don't
think I'll go that route just...

Hi,
What is the benefit of using the Pure option over the Mixed one. Is there a
better performance?
We have a lot of stuff in c++ with mfc support en we want to use in our .net
apps. With mixed setting we can compile including the mfc part of our code.
We can get rid of the mfc code but it will cost us some effort so we can use
the pure setting in that case.

The MSDN documentation says that the GetLastError function can give
undefined behavior when compiling with /clr:pure switch. Does this statement
apply to both C++ interop and P/Invoke? If yes, does it mean that we have to
use Marshal::GetLastWin32Error to check the last error code?

I have a small C++/CLI application which calls an unmanaged lib.
It seems like I can't use /clr:pure and link with the unmanaged lib (LNK1313
error).
The problem I have is that compiling with /clr adds a dependency on several
msvc*.dll:s which adds some unwanted complexity to the installation.
Is it possible to avoid the msvc*.dll dependency without explicit p/invoke?

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...

Dear forum friends,
With the development of smart home technology, a variety of wireless communication protocols have appeared on the market, such as Zigbee, Z-Wave, Wi-Fi, Bluetooth, etc. Each protocol has its own unique characteristics and advantages, but as a user who is planning to build a smart home system, I am a bit confused by the choice of these technologies.

Hello
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...
