PlaySound how to pause

[Forseth11]

I am trying to make a program that plays music and I am not able to make the user pause the music and be able to play where they left off.

This is what I have so far but I still need to know how to pause the music.

#include <iostream>
#include <windows.h>
#include <string>
#include <fstream>
#include <mmsystem.h>
#pragma comment (lib, "winmm.lib")
using namespace std;

int main(){while ( 1 ){
	long int A;
	PlaySound(TEXT("C:\\M0.wav"), NULL, SND_ASYNC|SND_FILENAME|SND_LOOP);
	cout << "\t0 = EXIT\n"
			"\t1 = STOP\n"
			"\t2 = PAUSE\n"
			"\t3 = PLAY\n";
	cin >> A;
	system ("CLS");
	if (A == 0){ exit(EXIT_SUCCESS); }
	if (A == 1){ PlaySound(0, 0, 0); cout << "To restart music: ";system ("PAUSE"); }
	if (A == 2){  }
	if (A == 3){  }
}
}

I know there are some include files that I don't need but I might use them later.

My question: How do I pause the music?

If you need to be able to pause the music, you will have to switch which API you are using. PlaySound does not support this functionality.

The easiest to use winmm call that does is probably mciSendString. Should be along the lines of:

mciSendString("open C:\\M0.wav alias MY_SND");
mciSendString("play MY_SND");

// etc

mciSendString("pause MY_SND");

// etc

mciSendString("resume MY_SND");

// etc

mciSendString("stop MY_SND");

// etc 

See MSDN for information about the mciSendString function and the various MCI command strings. I can't remember the actual signature of mciSendString, so the other unused params will all need default values in real code!

Note this is a rather old school approach, but should do what you want.

Is there any way to do it with playsound?

Well, no; because it does not support this functionality.

What's the issue with not doing it with playsound, anyway? If something else works you should just use it, surely?

ok

[Forseth11]

It gives me errors is there an include file or something?

[andywestken]

According to the MSDN entry for mciSendString, the header is mmsystem.h, which you already have?

What errors are you getting?

Note the fragment I posted earlier was for illustrative purposed only. As the MSDN entry says, the signature of mciSendString

MCIERROR mciSendString(
  LPCTSTR lpszCommand,
  LPTSTR lpszReturnString,
  UINT cchReturn,
  HANDLE hwndCallback
);

so the real code should be

mciSendString("pause MY_SND", NULL, 0, NULL);

etc.
