How to use mciSendString("play path",0,0,0) with exe path?

I'm using mciSendString("play path repeat",0,0,0) to play music in my project and I'm using it specially for playing multiple sounds in the same time.

The problem is that I want to put the sounds in the executable path so I used a function to get the exe path

string ExePath() {
    char buffer[MAX_PATH];
    GetModuleFileName( NULL, buffer, MAX_PATH );
    string::size_type pos = string( buffer ).find_last_of( "\\/" );
    return string( buffer ).substr( 0, pos);
}

but mciSendString() takes LPCSTR so I tried the following

string music_cmd="play "+ExePath()+"\\war1.mp3 repeat";
mciSendString(music_cmd.c_str(),0,0,0);

The program runs without Errors but it doesn't play the sound. How can I fix this problem ?

the path should have no spaces, if you use a path like as follows: C:\music\music 2.mp3 it will not work. to make it work delete the space or create a new path without spaces like as follows: C:\music\music2.mp3

Other Observations: the path should have less than 255 characters, relative path will not work (it works when you compile, but when you run the program on another computer, it will not work), cannot have spaces, otherwise it will fail.

there is a workaround you can do which is simple, you will be able to play with dots and spaces on the path

mine is as follows:

path = Application.StartuPath & `\whateverMusic.mp3`
path = Chr(34) & path & Chr(34)
mciSendString("Open " & path & " alias " & oName, Nothing, 0, 0)
mciSendString("Play " & oName, Nothing, 0, 0)

Public Property Name As String
    Set(value as String)
         oName = value
    End Set
    Get
         Return oName
    End Get
End Property
