VBScript Reference Manual InduSoft Web Studio
Graphics Script
The Graphics Script is located in the Graphics Worksheet folder. Procedures and Variables declared in
the Graphics Script interface are available locally but are not accessible by any Screen Script interface,
or from any other VBScript interface within IWS. Procedures and Variables declared in a Screen Script
interface are not accessible by the Graphics Script. If common Procedure(s) are required, they should
be put into the Global Procedures interface. Note that the Graphics Script is scanned (processed) by
IWS before the Screen Scripts.
The Graphics Script has three different pre-configured subroutines to execute VBScript code. These
subroutines execute the VBScript contained in them based on the event state of the Graphics Module.
These are:
Graphics_OnStart
Code contained within this subroutine is automatically executed just once when the Graphics Module is
started. This is a good area to initialize variables or execute start-up code.
Graphics_WhileRunning
Code contained within this subroutine is automatically executed continuously while the Graphics Module
is running. The rate at which this subroutine is called depends on the performance of the hardware
platform and other tasks running at the time.
Graphics_OnEnd
Code contained within this subroutine is automatically executed just once when the Graphics Module is
closed.

Key Notes:
• Do not change the name of the pre-configured subroutines in the VBScript
interface. Otherwise they many not properly execute.
