PV Allowed Input, Introduction

Home

4D View v16

The commands of this theme enable you to specify and read the 4D objects (variables, methods and commands) to which 4D View users will have access in the formulas of the current area. This operation allows the control of user actions in 4D View areas.

By default, the allowed input system is not activated (users have access to all 4D variables, methods and commands). Before using a command of this theme, you must first forbid all calls to these 4D objects by executing the PV SET DOCUMENT PROPERTY command with the pv no formula external call constant set to 1 (pv value on):

to forbid calls and activate the allowed input system:

PV SET DOCUMENT PROPERTY(area;pv no formula external call;pv value on)

to deactivate the system (default behavior):

PV SET DOCUMENT PROPERTY(area;pv no formula external call;pv value off).
