GETACTIVE()
Return the currently active Get object
------------------------------------------------------------------------------
Syntax
GETACTIVE([<oGet>]) --> objGet
Arguments
<oGet> is a reference to a Get object.
Returns
GETACTIVE() returns the Get object referenced by <oGet>. If <oGet> is
not specified, then the current active Get object within the current
READ is used. If there is no READ active when GETACTIVE() is called, it
returns NIL.
Description
GETACTIVE() is an environment function that provides access to the
active Get object during a READ. The current active Get object is the
one with input focus at the time GETACTIVE() is called.
Examples
. This code uses a WHEN clause to force control to branch to a
special reader function. Within this function, GETACTIVE() retrieves
the active Get object:
@ 10, 10 GET x
@ 11, 10 GET y WHEN MyReader()
@ 12, 10 GET z
READ
// Called just before second get (above)
// becomes current
FUNCTION MyReader
LOCAL objGet // Active Get holder
objGet := GETACTIVE() // Retrieve current
// active Get
BarCodeRead( objGet )
RETURN (.F.) // Causes Get to be
// skipped in READ
