// In an unmanaged DLL the following function must be called:
// int VFGeneralize(const BYTE * const * features);
// "features" parameter is supposed to be an array of byte arrays.
// function is Marshaled as follows:
static extern int VFGeneralize(byte features);
In C# I have the following:

Hi again,
I'm trying to call functions from a proprietary DLL but it's turned out to
be more difficult than I thought.
I have this W32.DLL which was written in C by USPS. They don't provide the
code so I only have the documentation.
I'm trying to call a function called z4date that, according to the docs,
returns the date as "an 8-byte character string in the "YYYYMMDD" format".
When I run it with this code I've written , I get "Can not...

I have been banging my head against the wall for a while now, and can't
seem to id the problem. I've been through a ton of posts and the code
doesn't seem any different. Can anybody see it?
When I call to GetTokenInformation I receive a buffer size (see
//HERE... comment in code), but when I let the code continue, asp.net
just sits there returning nothing, apparently on the
Marshal.AllocHGlobal call.
Here's the library function:

I need to read binary data file written by C++ program, using my C#
application.
How do i marshal the bytes i read with my C# code to .NET types.
The data is numbers (integers float doubles etc..) and strings.
I looked at the Marshal class but did not know how to use it with file.
Please add few code lines.
Thanks alot

Hi all!!
I am developing an app for a Pocket PC platform on C#. However, I need to make use of a C written dll. The problem arises when calling the function
.........
int capture_input( float32 ***cepstrum, int nrOfSeconds, int playBack, int *nrOfCoeff );
.........
where it returns an int (not an error code), a bidimensional array allocated within the function (cepstrum) and another integer (nrOfCoeff). I call the function from C#...

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,...

Hello
I'm a network technician in training and I need your help.

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...
