Mike:

(a) - You're sure the binary file actually contains what you think?

(b) - Maybe some code fragments might help in diagnosis of your problem.

cheers

I've got a question about reading Char strings into a struct from a bianary
file.

the first string gets read in correctly then the rest
is pretty much garbage.

Hey all...

I was just curious: what is the best way to have two things done at once in
an event loop.  What I mean is, if I have a lot of on screen updating that
must be flicker free and and a farely decent clip, I am currently updating
by using what I call a 2/3.  This means I have a global Boolean that I am
switching on and off, when it is off it redraws the screen, when on, it
processes an event, which if is a null event, updAtes the screen again,
therefor getting at most 2/2 or 1/2 refress per 'loop'.  I have set the
sleep time on my WaitNextEvent to 0 but I still want more speed per event
call.  Yes I could use a 1 in 3, but their MUST be an easier way.  If you
have no idea what I am talking about or have the solution, please e-mail me
for clarification and or the answer.  Thanx in advance.

It sounds as though what you really want to do is push the event loop
down a level and do your screen updates at a higher priority.  One way
to do this would be something like:

        void UpdateLoop()
        {
            long nextWNE;

            nextWNE = TickCount() + 30;
            while (!done)
            {
                DoScreenUpdate();
                if (TickCount() > nextWNE)
                {
                    CheckForEvents();
                    nextWNE = TickCount() + 30;
                }
            }
        }

Note that this is essentially pseudocode and serves simply to
illustrate the point.  The value '30' should be a global variable or
constant, depending on whether you want to allow the user to vary its
value to change the speed of the animation.  The CheckForEvents()
function should be a normal event poll and dispatch routine without
any of the screen update stuff (except for handling update events, of
course).

Hope this helps...

Mark
