hello,
I'm allocating a byte-Array in C# with byte byteArray = new byte;
Now I want to pass this byte-Array to a managed C++-function by reference,
so that I'm able to change the content of the byteArray and afterwards see
the changes in C#.
(if you wanna know more details: the goal is to write the content of an
existing char-array in c++ precisely into the passed byteArray, so that
after the function has proceded the content of the...

Hi,
I have mixed mode dll, which contains files with managed objects written in
MC++, and files with regular "C" functions.
One of those functions receives function pointer as parameter. I want to
pass to it delegate to managed object method.
I know how to do it from C# - DllImport etc. I suspect I can declare "stub"
method using those attributes, so it will actually reference "C" method, and
call this stub, letting marshaler to do the...

Any and all:
Is there an efficient way to pass a large array from .NET to COM? Can
references (or pointer) be passed from COM to NET and NET to COM without the
object it refers to being copied?
Thanks in advance.

I have an existing VC6 application using the MFC.
I am able to pass CString and other parameters from such a VC6 dll to an
unmanaged MFC dll (compiled in Visual Studio .NET).
Now I want to use .Net functionality, i.e. calling methods in managed code.
How do I pass CString variables for input and output usage, i.e. providing
and retrieving char arrays?
Regards,
Klaus

Hi,
my company is going to migrate a large VC++ application to .NET to
make use of Windows Forms (the old class library is not updated any
more). We are not planning to migrate the rest of the code which works
well.
I understand the basic concept: our code is unmanaged, Windows Forms
is Managed and Unmanaged may not call Managed code. I read about
Wrappers, PInvoke, Runtime Callable Wrappers for COM and about It just

Hi,
In our system we get image buffers through a native dll as void*. We want to
manage several of this blocks by C# objects an pass them wen needed to a
native image processing library.
What is the best way to do this? Can I just declare a unsafe pointer as
member of a class?
Best regards

Our application environment consists of three basic layers:
1. Third-party unmanaged DLLs that were written before the CLR was invented
and maintain a significant amount of information (including memory
management and connection pooling constructs) as static variables which were
intended to scoped to the process.
2. Managed C++ assemblies (.NET 1.1) that wrap the unmanaged DLLs as nice
neat classes with managed interfaces.

I would greatly appreciate some help on passing managed object into unmanaged
code.
I need to pass a reference (address of) of a managed class into unmanaged
code (written by a thrid party). The 3rd party unmanaged DLL will pass this
reference into standard Win32 unmanaged static callback function in my code.
Inside this unmanaged callback function I need to cast this unmnaged pointer
that I have received from 3rd party back into the...

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,...

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...
