Thread: sound and graphics in C - recommandation needed

In other words you haven't tried...

Read the manual, it's pretty straight forward. It's not going to teach you C, it will tell you how to use the API though.

That's strange, as they should be declared in windows.h - and you shouldn't need to:
1. Include winbase.h itself - it is part of windows.h
2. give a prototype for Beep - it's declared in winbase.h which comes from windows.h

Code:

#include <windows.h>

int main()
{
     Beep(1000, 500);
     return 0;
}

certainly works on XP (I just tested it) when compiled with gcc-mingw 3.4.2.

If that makes no sound when compiled with dev-c++ using gcc, then you haven't got a speaker inside your PC, or it's not connected correct (or something is broken in some other way).

Did you mean to have two spaces before DWORD, or just one?

Why would that make ANY difference?

Anyway I tried this one:

Code:

#include <windows.h>

int main()
{
    int i;
    for (i=0;i<100000;i++)
     beep(i*10,200);
     getchar();
     return 0;
}

No errors or warnnings but I didn't hear any sound ):

beep or Beep - note that C is case-sensitive, so "beep" and "Beep" are not the same function.

And yes, Borland functions only work in a Borland compiler.

Have you tried to compile my code with your compiler?

No, but aside from Beep instead of beep, I don't see anything wrong with it. I'm not going to subject my colleagues with an incrementally increasing frequncy from around 20Hz to 1MHz for several minutes either.

The code I posted definitely does work on XP. But I suspect the problem is that your PC doesn't have a speaker.
