how to open files

[ilia-c++]

Hello,

I'm trying to open a sound file in c++ and it just doesn't work!, if anyone knows the code for that then can they please send it.
Also is the code for opening and playing music files (wav) different from the code to open exe files or zip files.

Thanks Ilia

i=PlaySound ("C:\\WINDOWS\\MEDIA\\TADA.WAV", 0L,SND_FILENAME | SND_ASYNC);

be sure to include windows.h

[ilia-c++]

Thanks for the code, but I'm new to c++ and get 4 error messages, saying undeclared indentifier.
Would I need to declare them as variables, if so how

Thanks
Ilia

Did you #include <windows.h> ?

Your four errors are probably: i, PlaySound, SND_FILENAME, and SND_ASYNC. Here is the complete code that will do this:

#include <iostream.h>
#include <windows.h>

int main()
{
      bool i;
      i=PlaySound("C:\\WINDOWS\\MEDIA\\TADA.WAV", 0L,SND_FILENAME | SND_ASYNC);
} 

That should work. Be sure to set your project as a console app.

Two things...

1. iostreams are unnecessary in that program, since it doesn't produce any output.

2. It's <iostream> not <iostream.h>, you've picked the old non-standard header.

Apologies...

[parksie]

No need

The code works better but I still get this error message:

Can you post your entire code, please?

[ilia-c++]

// sound.cpp : Defines the entry point for the console application.
//

#include "stdafx.h"


int main(int argc, char* argv[])
{
return 0;
}

#include <windows.h>

int main()
{
bool i;
i=PlaySound("C:\WINDOWS\MEDIA\TADA.WAV", 0L,SND_FILENAME | SND_ASYNC);
}

[parksie]

You're not allowed two versions of main(). Use just the second half (from #include <windows.h>).

[wey97]

You also need to use double backslashes to avoid the character escape sequence errors.

...and 0L is redundant.

#include <windows.h>

void main(){

    bool i;
    i = PlaySound("C:\\WINDOWS\\MEDIA\\TADA.WAV",  0, SND_FILENAME | SND_ASYNC);

}

Also, PlaySound returns a BOOL which is just a synonym for int and not the same as bool.
And in this case, you can simply forget the return value of PlaySound.
