You can directly update the display of a PROGRESS control by assigning a value (which must be within the range defined by the RANGE attribute) to the control's PROP:progress property.
Example:
BackgroundProcess PROCEDURE !Background processing batch process
Win WINDOW('Batch Processing…'),AT(,,400,400),TIMER(1),MDI,CENTER
PROGRESS,AT(100,140,200,20),USE(?ProgressBar),RANGE(0,200)
BUTTON('Cancel'),AT(190,300,20,20),STD(STD:Close)
END
CODE
OPEN(Win)
OPEN(File)
?ProgressBar{PROP:rangehigh} = RECORDS(File)
SET(File) !Set up a batch process
ACCEPT
CASE EVENT()
OF EVENT:CloseWindow
BREAK
OF EVENT:Timer !Process records when timer allows it
ProgressVariable += 3 !Auto-updates 1st progress bar
LOOP 3 TIMES
NEXT(File)
IF ERRORCODE() THEN BREAK.
?ProgressBar{PROP:progress} = ?ProgressBar{PROP:progress} + 1
!Manually update progress bar
!Perform some batch processing code
. . .
CLOSE(File)
