Playsound

can someone help with this error:
c:\documents and settings\hp_administrator\my documents\visual studio 2005\projects\soundtest\soundtest\sound test.cpp(14) : error C2664: 'PlaySoundW' : cannot convert parameter 1 from 'const char [12]' to 'LPCWSTR'
Types pointed to are unrelated; conversion requires reinterpret_cast, C-style cast or function-style cast

Can help me understand sound(s) in c++ better.

Thanks. Thanks. Thanks.

You're trying to pass a ANSI CHAR string to a function that expects UNICODE CHAR string.
Either use a conversion function to convert between the two, or if you're simply passing a string, you can put L before like L"file_to_play.wav" (instead of "file_to_play.wav").

Or you can just call PlaySoundA instead.

Most likely, you have unicode set to default in project options. You can change that. There's usually two different versions of each API, one for ANSI and one for UNICODE.

Or learn to write code which is ANSI and UNICODE compatible at the same time by doing say
PlaySound(TEXT("file.wav")

Or PlaySound(_T("file.wav"))
But erm, this is all if you write the file yourself, of course. It won't work with ANSI STRING variables (and vice versa).

Which is why there is a whole section of MSDN devoted to describing macros, data types and functions for writing code which is compatible with both approaches.

Try reading it sometime.

I put the following code... and I don´t know why I got this error:

Compiler: Default compiler
Building Makefile: "C:\Dev-Cpp\Makefile.win"
Executing make...
make.exe -f "C:\Dev-Cpp\Makefile.win" all
g++.exe -c "sonidos 3.cpp" -o "sonidos 3.o" -nostdlib

g++.exe "sonidos 3.o" -o "sonidos3.exe" -mwindows winmm.lib -lobjc -nostdlib

g++.exe: winmm.lib: No such file or directory

make.exe: *** [sonidos3.exe] Error 1

Execution terminated


And this is the code: ^

Code:

---


#include <windows.h>
//#include <winmm.lib>
#include <mmsystem.h>
#include <conio.h>

using namespace std ;

int main()
{
PlaySound(TEXT("prueba.wav"), NULL, SND_ALIAS | SND_APPLICATION);
return 0 ;
}

PLEASE HELP ME!!!
