AMIP hotkeys are working on 32 bit applications but not on 64 bit applications

[winamp_noob]

Hi!

I'm almost complete noob in terms of Visual C++ programming, but author sent me a source of AMIP plug-in and I'd like to get the basic idea how to fix this annoying issue.

Issue is:

in 32 bit applications plug-in pastes via hotkey information correctly about the current playing tune

in 64 bit applications plug-in is not working

here is a snip from hotkey binding function (or definition?):

code:
UINT register_hotkey(

  const char * ini_filename

  , HWND hwnd

  , const char * atom_hotkey_str

  , UINT hk_defs[defs_what_last]) {



  UINT atom_hotkey = GlobalAddAtom(atom_hotkey_str);



  if (!atom_hotkey) {

    LOG("AddAtom Failed");

  }



  char buff[MAX_LINE];



  if (!strcmp(atom_hotkey_str, ATOM_PASTE_STR)) {

    strcpy(buff, cfg["PasteHotkey"]);

    LOG(buff);

  } else if (!strcmp(atom_hotkey_str, ATOM_REGEX_STR)) {

    strcpy(buff, cfg["RegexHotkey"]);

    LOG(buff);

  }

  parse_hotkey_string(buff, hk_defs);

  if (!RegisterHotKey(

        hwnd, atom_hotkey, hk_defs[defs_mods], hk_defs[defs_vk])) {

    LOG("!!! Register hotkey failed");

    atom_hotkey = 0;

  }



  return atom_hotkey;

}

what could be main difference between 64/32 bit hotkey binding?

Thanks a lot.

EDIT: I've checked gen_hotkeys.dll plugin bundled with Winamp and it works in x64 applications! anyone have a clue about relevant code in this plugin regarding hotkeys?
