It wasn't faster on mine (686-120, Borland C, Win95). In theory it's
faster, but not when you take into account all the dereferencing and
addressing that goes on. An imul doesn't take that long so you can't
really do much to replace it. Your method (on my computer) gives about
the same performance as a simple y*320+x, except it requires more code
and memory. It may be faster on other chips though.
Danial.
PS. Thanks for the info on DCT. I have 1 question though. You said that
it compresses it based on how fast it changes. Does this mean that it
would start with a number, then for each subsequent pixel, add a certain
number to the previous number to get the value for the pixel?

Yep.
I guess really, so long as you don't need lots of frames per
second (ie. not more than 10 or so), it doesn't really matter what
method you use. They are both about the same. And given the speed of
today's processors, and the compilers, it doesn't matter in terms of how
smooth the video is (I mean, shifting or multiplying won't affect
it). You should just not plot too many pixels. If you plot too many
pixels then you should change the algorithim.

Write your reply.

assistant: Hi,
 Back onto mailslots. I was doing what you said (get every 2nd message),
and it worked. Until I sent two message together (ie, send one message
then send another immediately after - no pause), and for the first
message, it only sent it once. So this method doesn't work _all_ the
time. So I came up with a better idea. When you send each message, add a
packetnumber to the front. Then, when you receive a message, check if
this packetnumber is >= the last packetnumber. If it is, discard the
message. It's more complicated to implement, but at works all the time
(as far as I can tell).
Later,
Danial.

If you used:

Then yes, the compiler is wrong.
Think of it this way:  here is your "A" structure (memory wise - unsigned

Hmm...I'm not sure I agree here.  First of all, I'd point out that the
current draft of the C++ standard includes classes for vectors, maps,
etc.  Despite them being included with the compiler, you can develop
your own instead.
Unless I'm badly mistaken, the same is basically true in Java as well.
However, I don't use Java much since it's not particularly suited to the
sort of work I do; as such, my comments on details about Java should be

No - the current PCI bus is 32 bit as well.  The bus from the CPU to
memory is 64 bit on a Pentium.
None of this is really relevant at all.  The bus size makes no real
difference.  In fact, the bus between the computers is typically
Ethernet, which is exactly ONE bit wide.  The simple fact is, you pick a
block of data and send it out over the Ethernet card.  On the other end,
it comes into memory.  There's no question that at a hardware level,
communication is possible without getting data duplicated and such.  If
the duplication is taking place, it's purely a software problem,
unrelated to bus sizes and such.
