Adding app to the Start Menu On PocketPC

Actually, you'll need to edit the registry setting for that.

check registry "HKEY_LOCAL_MACHINE\Taskbaritems", youll see some string values and its organizd in this way:

"NUMBER" - this is the total number of items in the start menu.
"FILEX" - this is the location where the itm exe is stored. 'X' is a number in sequence.
"NAMEX91" - this is the name as it appears in the start menu. 'X' again is the number in corrspoinding to the "FILEX".

So to add a new one, increase the "NUMBER", add new string "FILEX" and "NAMEX91" where 'X' is the same as the "NUMBER" value. Try playing with the registry, you'll know how it works. ;)
