    Accessing hardware directly (equivalent) in XP

    I've been working on a program on a Windows 2k computer, its a console application. It won't do anything at my home computer (running windows XP) because it uses the beep() function to access the PC speaker directly.

    Now, since I'm using XP and it doesn't like my accessing the PC speaker directly, is there some other function or some way to make it beep different tones in XP (other than installing the DOS files like command.com)?

    Thanks!

    Beep() works fine on my XP system.

    Really... it doesn't give an error, but it won't play any tones. I'm using MVC++ 6.0, but that shouldn't matter.

    Irritating, but perfectly functional...

    Code:
    #include <windows.h>
    
    int main()
    {
    	Beep (523, 500);
    	Beep (587, 500);
    	Beep (659, 500);
    	Beep (698, 500);
    	Beep (784, 500);
    	Beep (880, 500);
    	Beep (988, 500);
    	Beep (1047, 500);
    	return 0;
    }
    ... does your internal speaker ever beep, i.e. do you have one, is it connected etc...

    *** EDIT ***

    Also MS VC++ 6.0 Pro.

    Yes, I have one. I also have regular speakers.

    One quick question: do you have a sound card?

    From memory, there is an onboard sound chip on the mother board I have, never used it. The speakers connected to the system are turned off, (only ever used to listen to cricket commentary streaming from where ever a match is going on!).

    I cannot believe that is significant. The SDK docs would say if it had been replaced in XP.

    Hmm. I forgot to mention that it doesn't make any noise at all.

    What, ever? When you boot does the internal speaker beep at all, (speakers switched off)? What I'm trying to find out is if, in fact, your internal speaker is working - you say you have one - are you sure it works?
