I am having problems accessing a managed object from
unmanaged code. Specifically, I have a .NET forms
application with a web service proxy. The forms
application links to an unmanaged DLL which uses callbacks
to receive data via TCP. The data received in the
callback must be passed to a web service via a web method
provided by the proxy. So the callback (which is
unmanaged code) needs to access the proxy (managed object)
to send the...

Hello Esteemed Developers and Experts,
I have been using Microsoft Visual C++ .NET for 1 year. During this time,
I have searhed some topics over internets. Most of the topics about .NET is
related to C# and Visual Basic .NET. There are less documents about Visual
C++ .NET or Managed C++.
I wonder the reasons of below questions:
1) Is C# more powerful than Managed C++ and Visual C++ .NET?
2) Is Microsoft intending to support C# and...

We have an application completely written in C++ under visual studio v6. One
of our customers wants to use some of our existing components in his project
but doesn't know C++ and isn't interested in learning it. He does know C#
and VB though.
Whats the best option for us (ie. minimum work) to provide him with an API
that he can use in his own applications? I was originally considering a COM
interface, but looking into .NET, I'm wondering...

Hi Guys,
I am trying to access a class in an unmanaged dll. I have
created a wrapper managed class to access the functions I need but no matter
what I try from the MSDN samples I can not get it to work with my code. I
have a VB Net front end which need the access the unmanaged functions. The
wrapper I wrote can be accessed but the wrapper will not compile when I
refer to the unmanaged class. I have tried using header file for definitions...

STILL trying to wrap an unmanaged C++ class that is itself a wrapper to some
COM stuff, not sure, it is littered with LPDISPATCH and InvokeHelper, etc.
Problem is, when something goes wrong, I'm having a hard time debugging.
In my managed C++ class(the one wrapping the unmanaged C++) I have a method
that looks like this:
bool FindFileItem(String* filename, IVSSItem& founditem);
that method calls the unmanaged method:

Hi,
What is the best case for accessing managed code from unmanaged C++ code,
considering that the unmanaged code doesn't have managed extension?
Please reply.
Thanks in advance.

I'm having trouble accessing an unmanaged long from a managed class in
VC++.NET
When I do, the contents of the variable seem to be mangled. If I
access the same variable byte-by-byte, I get the correct value.
Regardless what I set the variable to, the value that is returned for a
long is always the same value. What's going on...can anyone help me?
A short version of the code follows:

Hi,
I have some legacy ASP web applications that use an unmanaged COM
component to connect to a third party application. The third part
application has moved to the managed code in the current release with
backward compatibility with the unmanaged code.
In the future releases, the vendor is going to drop backward
compatibility and as a result of that all our legacy ASP applications
will break.

Hi,
I've realized that my good fortune of not having my computer go into
standby mode was the result of my application accessing a file on a
shared network drive. Not going into standby is a very good thing for
my application, but I don't want users to be required to share a drive
and file just to accomplish this.
I've read in old posts in various places stating that by importing
kernel32.dll I could access a function called

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,...

I am currently learning how to create and manage the different types of VPNs and I have a question about LAN-to-LAN VPNs.
