Hi, I am trying to figure out how to use unmanaged code using P/Invoke. I
wrote a simple function which takes in 2 buffers (one a byte buffer, one a
char buffer) and copies the contents of the byte buffer into the character
pointer. The code looks like the following:
#include <stdio.h>
#include <stdlib.h>
#include "stdafx.h"
BOOL APIENTRY DllMain( HANDLE hModule,
DWORD ul_reason_for_call,

I have a VB.Net (1.1) that uses SQL-DMO via COM Interop to create a
linked server. The code throws an exception, as it should, when the
linked server I am trying to create already exists on the server. If I
were coding this directly in ADO.Net, then the excerption thrown would
be a SQLException which I could catch and read the errorcode, which
would tell me that the error is "linked server already exists".
However, the error thrown is a...

If I write a pure C# application, only using the standart publi API, no
interop, the same binary should work well on32 bit, 64 bits and perhaps on
the compact framework as well if I link against it.
Now how could I achieve the same thing if I do interop and I have a managed
C++ API?
let say I have a managed C++ module compiled for 3 different target but with
always the same interface:
mycppmodule32.dll

Hi,
I have a logger.dll (unmanaged c++ dll compiled in vs2005).
I have a C# interop to use that dll in managed code implemented in
Interfaces.dll (used by other C# dlls).
I also have a number of other C# dlls referencing Interfaces.dll and
using logger.dll interop for logging.

Hello -
I am getting a compile error "Expected class, delegate, enum".
I am trying to create a Class Library in C# which wraps around an unmanaged
DLL that manages a MIDI interface.
In my Class Library code, I have tried to put a DllImport to the Win32
function MessageBox. Just to test out the DllImport functionality before I
add my custom functions that I want to wrap.

Hey there, this will be somewhat a long post, but any response is
appreciated!
I have done many PInvoke in the past from C++ to C#, but I did PInvoke
within C# not C++/CLI.
Can someone explain more why C++/CLI would be better to PInvoke than doing
the PInvoke in
C#?
Because, usually in C# as you already know we use DLLImport and extern

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...

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...
