Hello,
I'm starting to investigate cs, managed c++ and interoperating with a very
large unmanaged code base. We are going to use Windows Forms (written in
cs) to replace our old fashioned GUI. The guts will remain in unmanaged
c++. So I need to write public managed c++ wrapper classes for the couple
of interfaces the unmanaged stuff needs to expose for the GUI.

Hi Newsgroup,
General C# questions. If I have a class(es), of API functions just as they
are. Would that be considered Unmanaged or unsafe (not meant as the c#
keyword) code? If I implement error checking, and disposing appropriate
resources for those functions would my program then be considered managed
(or safe)?
In general I'd like to ask (not just with API functions) can you construct
an assembley that would confirm to the...

Hi
I was wondering if there are some issues with socket support in this
situation :
- Main program is unmanaged C/C++ which is using windows sockets for its
coms to other unmanaged programs
- The program includes some new C# managed components (via unmaged to
managed interfaces) which
internally are using .NET framework sockets for its coms (to another server

We use StackWalk(StackWalk64) from dbghelp.dll to walk our
callstacksas needed, using the various Sym* methods
(SymGetSymFromAddr, SymGetLineFromAddr) to resolve source file,
function name, and source line number for each frame. This works fine
for unmanaged code, but when we have a call stack that goes into or
through some managed code, we cannot resolve any info for the managed
frames - we can however, get all the information for the...

I have a 3rd party application that can reference external dll's. The dll's have to be written in unmanaged code with an exported function I can reference and call. I would like it to call a C# dll file but it cant call a managed C# dll. I need to create an unmanaged C++.net wrapper for a Managed C# dll. Does anyone know how to do this? can you please give me a simple example of what the C++.Net code would look like to do this

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

I am trying to create an managed wrapper but have some problems with it by
using abstract classes.
In my unmanaged library code i had the following three classes with the

I have legacy DLL code written in C++ that is essentially C code, an
implementation of a set of formulas used in our industry. There are no DB or
GUI interfaces, just exposed methods. I would like to convert it to C# and
if that is not possible to manage C++. I want to use the DLL in a larger
VB.Net program.
Is there a tool that will convert C++ to C#?
Are there any articles/papers/examples on converting C++ to C#?
Are there any...

Hi All,
Currently we have COM component(dll) implemented using ATL.
Because of the current business requirements, we would like to rewrite
the COM component in Managed C++ and the clients will be unmanaged C++
and C# .
I have been searching net to find some sample code and but could not
get it.

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...

Overview:
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,...

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. I'm particularly interested in Zigbee because I've heard it does some...

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...
