Method AutoFill: nKey was not defined as a LOCAL. Fixed.
Method AutoFill: nLength was mispelled (as nLenght). Fixed.
Method AutoFill: ::Cargo changed to ::lAuto (see reason below)
Method AutoFill: Changed to using vkey.ch manifest constants instead of numbers.
Method Redefine: Was passing aItems to the parent method (not needed).
Method LostFocus: Added this method.
Methos New() and Redefine(). Was passing bChanged, and then ::bChange to parent. Fixed.
It is not a good idea to use ::Cargo, ::bPostKey, or ::bLostFocus in the class since these
then cannot be used by the programmer. It would be better to subclass the needed methods and add
whatever functionality needed. So, ::Cargo and ::bLostFocus were eliminated.
Unfortuneately, not using ::bPostKey is somewhat of a challenge. We can subclass KeyDown() and
KeyChar() but some of each method will have to be copied into the new methods and thus if there
are any changes to these sections of code in future versions of TGET, then this method in
TAutoGet will have to be updated also.
Bug?: If the items in ::aArray are in proper case, e.g. "Mauro," they are automatically converted
to proper case when autofilled, however, if you backspace they are converted to all lower case.
