c++ - マウス カーソルが 32 ビットでは変化するが 64 ビットでは変化しない

Question

これらの MAKEINTRESOURCE 、 GetClassLong 、 LOWORD((LPSTR)cursor_name) 、および LoadCursor のうち、いずれかが 64 ビットに対応していませんか? そうでない場合、解決策は何ですか、私のコードは32ビットでは正常に機能しますが、64ビットでは機能しません。コードは巨大なアプリケーションであり、使用される主な関数は上にリストされています...関数にはパラメーターmouse_formがあります

  HCURSOR c_cursor, n_cursor;
  LPSTR cursor_name;

    switch( mouse_form )
    {
            case MOUSE_WIN_ARROW:
                    cursor_name = (LPSTR)IDC_ARROW;
                    break;

            case MOUSE_ARROW:
                    cursor_name = (LPSTR)IDC_ARROW;

                         #if (!(defined WIN32) && !(defined WIN64))


        if( environ_get_window_id() != -1 ) cursor_name = (LPSTR)IDCC_ELXHND;

    #endif
                    break;

            case MOUSE_CURSOR:
                    cursor_name = (LPSTR)IDC_IBEAM;
                    break;

            case MOUSE_HOURGLASS:
                    cursor_name = (LPSTR)IDC_WAIT;
                    break;

            case MOUSE_POINTING_HAND:

                        #if ((defined WIN32) || (defined WIN64))
                                cursor_name = (LPSTR)IDC_ARROW;
                        #else

                cursor_name = (LPSTR)IDCC_ELXHND;
                        #endif



                    break;

                    cursor_name = (LPSTR)IDC_CROSS;
                    break;

                    cursor_name = (LPSTR)IDC_CROSS;
                    break;

            case MOUSE_OUTLINED_CROSS:
                    cursor_name = (LPSTR)IDC_SIZE;
                    break;

            case MOUSE_MENU_ARROW:
                    cursor_name = (LPSTR)IDCC_ELXMEN;
                    break;

            default:
                    cursor_name=(LPSTR)MAKEINTRESOURCE( mouse_form );
    }
