Thanks for the example!! I will try it to find out if I have the boost libraries. I never knew there was a function to beep the sound card, I will look into that. I want this to work whether I have my speakers on or not, mainly for my dorm where my only speakers are headphones I am not always wearing. I can have them both beep, though... I will keep tweeking it, as well as put it onto my pc in my compiler so I can see just how it works; reading it in braille on my braillenote is not quite the same thing. I always thought braille would be easier for coding, but I am now so used to speech that using braille is often slower and more confusing. Anyway, thanks again and I will let you know if I do not have the boost library.
Have a great day, Alex

Alex I want to first say if I was doing this I would make sure to
not use
just beep and I would code in a call to the wave function so you
could use a
sound card. I guess if the person didn't have a sound card you
could check
for it and then use the pc speaker. With that said I liked your
little
project and though I would show you how it would be done with the
boost
thread and date libraries. Now if you don't have boost installed
I can tell
you how to do that if you want to. Here is the code that I made
though and
it works.
#include "boost/date_time/posix_time/posix_time.hpp" #include <boost/thread.hpp #include <boost/bind.hpp #include <iostream #include <windows.h #include <string
using namespace boost::posix_time; using namespace boost::gregorian; using namespace std;
enum PERIOD
{
HOUR,
QUARTER,
HALF,
THREEQUARTER,
};
bool beeps = true;
void
chime (PERIOD when)
{
int
chimes = 0; // used to repeat chimes for the
minutes
long LastChime;//used to not repeat when it has already chimed //get the current time from the clock -- one second resolution ptime now = second_clock::local_time ();
//set the start last_time so that it doesn't ring instantly if (when == HOUR) LastChime = now.time_of_day ().hours (); else LastChime = now.time_of_day ().minutes ();
while (1)
{
Sleep (1000);
now = second_clock::local_time ();
if (beeps == true)
{
switch (when)
{
case HOUR:
if (LastChime != now.time_of_day ().hours ())
{
for (long i = 0; i < now.time_of_day ().hours ();
i++)
{
Beep (244, 500);
Sleep (500);
}
LastChime = now.time_of_day ().hours ();
}
break;
case QUARTER:
if ((LastChime != now.time_of_day ().minutes ()) &&
(now.time_of_day ().minutes () == 15))
chimes = 1;
break;
case HALF:
if ((LastChime != now.time_of_day ().minutes ()) &&
(now.time_of_day ().minutes () == 30))
chimes = 2;
break;
case THREEQUARTER:
if ((LastChime != now.time_of_day ().minutes ()) &&
(now.time_of_day ().minutes () == 45))
chimes = 3;
break;
}; //end switch
if (chimes > 0)
{
for (; chimes > 0; chimes--)
{
Beep (488, 500);
Sleep (500);
}
LastChime = now.time_of_day ().minutes ();
}
} //end if beeps true
} //end while
}
