Using v1.1. of the framework:
I was writing a wrapper around the java.util.zip.ZipOutputStream class so
that my app could access it using standard FileStream semantics and I ran
into a conversion problem. The signature for the write method is void
ZipOutputStream.Write(sbyte array,int off,int len) so I figured a simple
conversion from byte to sbyte would do the trick.
Now, my understanding of an sbyte is that it is a signed byte that...

I'm looking for the alogithm to take a piece of 8-bit audio data, and
scale it to a 16-bit short. I got as far as:
private static short ByteToShort(byte b)
{
int word = 0;
word |= ( ( b & 0x01 ) << 1 );
word |= ( ( b & 0x02 ) << 2 );
word |= ( ( b & 0x04 ) << 3 );
word |= ( ( b & 0x08 ) << 4 );

I am using binary writer to write an array of bytes to disk. However, my data starts out as an array of sbytes. I am currently type casting each array element in a for loop. Is there a faster method for converting an array of sbytes to an array of bytes?
Thanks,
Darrel

Please keep in mind that I am a PowerBuilder developer working on his first
..NET project.
I have a VB.NET console app that is responsible for taking MS Word docs and
getting them into an Oracle 9i database using a BLOB column.
I have read in the file using a file stream and then put it in a byte array.
The problem is that I need to compress the byte array before inserting into
the database. I have tried to use ZLIB, but I cannot get...

Hello, Maestros.
Following on from the posts on creating structs from a byte.
The methods described there work well. But I seem to have struck a snag that some might find interesting. The C/C++ structs that give problems all have the same issue: they all have at least one field something like this:
char character
There does not appear to be any way to do this in c#. The closest I could get was
fixed sbyte character.
This does indeed...

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...

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...
