Hi folks, I''m trying to initialize a DirectMusic object, but I need to pass the executable''s directory as a WCHAR to the Loader->SetSearchDirectory function. In a tutorial I saw the MultiByteToWideChar function that convertes CHAR to WCHAR, but when I use it, it only copies one character to the destination buffer. Does anyone know why this happens? The macro for the function is:

#define MULTI_TO_WIDE( x,y )  MultiByteToWideChar( CP_ACP, MB_PRECOMPOSED, y, -1, x, _MAX_PATH );

funtion()
{
    char szDir[_MAX_PATH];
    WCHAR wszDir[_MAX_PATH];

    if(_getcwd( szDir, _MAX_PATH ) == NULL)
    {
        return NULL;
    }

    // at this point szDir = "D:\cpp\Direct3D tutorial 1"

    // convert szDir to wszDir
    MULTI_TO_WIDE(wszDir, szDir);

    // wszDir = "D"
}

I hope you folks can help me so I won''t have to make a ''dead'' game. If there is a better function than _getcwd to get the directory where the program executable resides (preferably as a WCHAR), I sure would like to hear about it too. Dennis

instead of query for the .exe directory

you can use ".\" and it will default to the "working directory" enter in the short-cut (9/10 its the .exe path too, and you can change the short-cut if its not)

Thanks for the advice, but I really need the conversion. Maybe someone else can help me?
There must be someone who knows the MultiByteToWideChar() function.

TEXT("exe path"); should do. Just #define UNICODE before it then #undef it after.

Of course, you can always declare the executables directory as a wchar_t variable.

this what you wanted?

There are DirectX utility functions to convert to/from Unicode now.

Look at the DX8 DirectPlay SimpleServer sample and search for something like "wszSessionName". It''ll be there.

Thanks for all the help folks. I better get some work done, real fast.
