Include sound

Experts out there again,
Could you all give me some help. This one is really simple. May I know how to include a sound in my C++ program that keeps on looping. Also, may I know how to include a button for user to click so that the sound will stop playing. Futhermore, may I know how to include a sound that plays only once.

Currently I am using Visual C++ on Windows 98.

I will increase the points if answers are excellent. Please help a beginer in C++.

Thanks,
hongjun

Hi:
Here is a little sample for playing MIDI sounds. Let me know if you want any other type of sound *WAV, etc.).
The sample is an MFC one.
Happy coding!

There are 9 files in the sample:
midi.cpp
midiDlg.cpp
midiPlayer.cpp
stdAfx.cpp

midi.h
midiDlg.h
midiPlayer.h
stdafx.h

midi.rc
resource.h

Sorry olgat,

I understand that your answer must be the correct one. However, I find difficulty in finding the source codes for each file especially midi.rc.

If you do not mind the trouble, could you send those files to my email account

asteroids_88@hotmail.com

I believe this will be of great help to me. By the way, I have increased the point for this question from 120 to 130 as an encouragement. I will however increase this if your codes are satisfactory and I might grade you a A because I can see that you are keen to help.

Hope to hear from you soon.

Thanks,
hongjun

I think if you want to play a sound you have it as a file. You can use this function to play a file:

PlaySound("C:\example.wav",NULL,SND_FILENAME|SND_LOOP|SND_ASYNC);

You can delete SND_LOOP if you don't want the sound to loop.
If you want to stop a sound you can call the same function:

PlaySound(NULL,NULL,NULL);

gambistics

Sorry I forgot a thing. You have to include "mmsystem.h":

#include "mmsystem.h" and under the tab "Link" you have to specify "winmm.lib" at object/lib files

What do you mean by
under the tab "Link" you have to specify "winmm.lib" at object/lib files
