Hello,
What is the proper way to read a directory such that file names are not
garbled? Here is the example I borrowed form the std.file
documentation.
Screen shots of folder is attached. Thanks.
void main(string[] args)
{
bool callback(DirEntry* de)
{
if (de.isfile)
mciPlay(toUTF8(de.name));
return true;
}
listdir("snd",&callback);
}
D:\code>play
snd\american.ogg
snd\bigdog.flac
snd\blackmail.mp3
snd\ding.wav
snd\kam.aif.aiff
snd\豺｡縺・ogg

Much appreciate the info. I'm not however interested in outputting to
the console. I'm trying to call mciSendString with the name of each
file contained in the directory. The process fails however, when it
encounters a Japanese file name. Please see code below. Any idea what
I'm doing wrong?
import std.file;
import std.string : cstring = toStringz;
import std.c.windows.windows;
pragma(lib, "winmm.lib" );
extern(Windows) {
uint mciSendStringW(
LPCWSTR lpszCommand,
LPWSTR lpszReturnString,
uint cchReturn,
HANDLE hwndCallback);
}
void main(string[] args)
{
bool callback(DirEntry* de)
{
if (de.isfile)
mciPlay(de.name);
return true;
}
listdir("snd", &callback);
}
void mciPlay(string audio)
{
uint mciSendString(string s)
{
return mciSendStringW( cast(LPCWSTR)s, cast(LPWSTR)null, 0,
cast(HANDLE)0 );
}
auto exists = mciSendString(`open "` ~ audio ~ `" type mpegvideo alias
myFile`);
auto played = mciSendString("play myFile wait");
scope(exit) mciSendString("close myFile");
}
In short : never rely on the casts to do the right thing.
Bug is here:
return mciSendStringW( cast(LPCWSTR)s, cast(LPWSTR)null, 0,
cast(HANDLE)0 );
changing that to more accurate:
return mciSendStringW(toUTF16z(s) , cast(LPWSTR)null, 0, cast(HANDLE)0 );
works for me, even with this name:
snd\와카미야 온마쓰리.mp3
If you use W version you need to re-encode your UTF8 string to UTF16.
AFAIK Windows uses slightly outdated version of UTF16, check the web on
issues.
That's it! Thank you much. I tried the toUTFXX() function calls but
completely missed toUTF16z.
