Report was sent to printer

With SET REPORTBEHAVIOR 80 is easy to check if a report was  sent to printer (directly or via preview)

SYS(2040) is very useful, but its value is relevant only inside the report. So SYS(2040) will be saved into a private or public memory variable, from one of the Summary band events, or Page footer band events.

Example: at ON Entry in the Page Footer Band, place :

_vfp.setvar("MyFlag",sys(2040))

where MyFlag is a private or a public variable

In the calling procedure / method:
...

PUBLIC MyFlag
MyFlag="0"
REPORT FORM ...
DO CASE
CASE MyFlag="1"
  MESSAGEBOX("Report is in Preview Mode")
CASE MyFlag="2"
  MESSAGEBOX("Report is being sent as output (such as a printer or file).")
ENDCASE
