||
|| SERVICES: Sample applet using AEE
||
|| DESCRIPTION
||    This file contains the implementation of a simple example using the
||    AEE services.
||
|| PUBLIC CLASSES:
||    N/A
||
|| INITIALIZATION AND SEQUENCING REQUIREMENTS:
||   The following explanation applies to this sample containing one applet which serves
||   as a base for app developers to create their own applets using AEE Services:
||   
||
||   In the applet source file (like this one), include AEEAppGen.h.
||
||   Mandatory Sections in Applet Source (this file):
||   -----------------------------------------------
||   Following Mandatory Sections are required for each applet source file. 
||   (Search for "Mandatory" to identify these sections)
||
||   Includes:     
||      Copy this section as-is from the sample applet. It contains:
||      AEEAppGen.h: For AEEApplet declaration
||
||   Type Declarations:
||    A data structure must be defined to hold the app specific data. In this structure,
||    the first element must be of type AEEApplet.
||
||   Functions: (For more details, see corresponding function description in this applet)
||
||      App_HandleEvent(): is the Event Handler to this applet.
||                         Copy the function outline from the sample applet and add app specific code.
||
||      AEEClsCreateInstance(): creates an instance of the applet and initializes it. 
||                              It is called by AEEModGen when applet is being created.
||
||   
||
||    Important Notes:
||    ---------------
||    1. DO NOT use any "static data" in the applet. Always use the
||       functions exported by AEEStdlib or by IHeap services to
||       dynamically allocate data and make it a member of the applet
||       structure.
||
||    2. DO NOT include and link "standard C library". Use AEE Memory
||       Services (in AEEHeap.h) and Standard Library macros(in
||       AEEStdLib.h).  For example, use MALLOC() to allocate memory,
||       WSTRCPY() to make a copy of Unicode (wide) string.
||
||    3. BREW is Unicode(wide string) compliant ONLY (no ISOLATIN1/ANSI)
||       except for file names which are ISOLATIN1/ANSI.  ALWAYS USE
||       AECHAR instead of "char". Use string services provided in
||       AEEStdLib.h for string manipulation.
||
||    4. It is always a good idea to DEFINE RESOURCES using BREW
||       ResourceEditor. Make Strings, Bitmaps, Dialogs, etc.  as
||       resources. ResourceEditor saves resources as .bri file,
||       generates resource header file and compiles .bri into a .bar
||       binary file, which can be used by the applet.
||
||    Miscellanoeus Notes:
||    -------------------
||    1. Make sure that the class ID used for the app is the same as that
||       defined corresponding in .MIF file
||    2. Always make sure that compiled resource (.bar) file and corresponding
||       resource header (a) reside in app directory and (b) are included in
||       the applet code. Define a constant APP_RES_FILE containing the name
||       of the compiled resource file (with .bar extension).
||
||    More than one applet:
||    --------------------
||    If more than one applet needs to be defined, then do the following
||    (1) Follow the above description for each applet
