7. Brief Intro
Why VBScript?:
It is a quite well known high-level programming language
Simple, Flexible and Standard
Runs on Windows Embedded OS and Internet Explorer
It is similar to VBA, which is also used on other MS Applications such as the
MS-Office suite
Which IWS interfaces support VBScript?:
Script Task, Global Procedures, Startup Script, Screen Script, Graphics
Script, Command animation property, ActiveX and .Net controls Methods
 Support to Built-in IWS functions and tags on VBScript Environment

8. VBScript Cool Features!:
Use of Variables on the Script!
Save on tag count!!!
Intellisense: auto-complete
(less typing, more doing)
Create your own Functions and
Sub-routines
 Find on the Internet scripts with
examples on how to do things that
you are not sure how to do!

10. Database Spy:
 It works to debug project running on the local machine or in remote
ones
 Used to see and load values into tags
 It can also execute Built-in Functions or call VBScript procedures
Sub-routines
 NEW!!! Support to seeing VBScript variables values and functions
status

11. Output Window / LogWin:
 Helps to debug almost all IWS tasks, such as Comm Drivers, OPC
messages, Database transactions, Screens load time, Log tag changes, and
so forth
 Like the DBSpy, it works for both Local and Remote projects
 TRACE messages has been the biggest friend on debugging scripts until
now
 It can save Log Files

13. What can be debugged?
 Global Procedures
 Graphics Script
 Scripts from the Script task and Startup Script
 Screen Script and Graphics Script
What is not supported yet?
 Command Properties on screen objects
 ActiveX and .Net Controls Methods

14. The new DEBUG tab
 It only appears when a supported VBScript interface is open
 Allows the user to select between Debugging the Viewer module or the
Background tasks
 It is where the user controls the debug execution by starting, stopping, going to
the break points, Stepping Into a function, Over and Out as well.

15. Break Points
 Used to identify important sections
that you want to focus your debugging
process
 Temporarily suspends the script
execution on that point
 During that break time, the user can
check variable values, execution states,
and be prepared for the next steps

16. Stepping through
 Once the execution in in Break mode, the
user can:
 Step Into: advances a single step
forward
 Step Over: advances a step on the main
Script, not stepping into function calls
 Step Out: if the main script called a
function and is debugging there, this
command will finish the execution and
return to the main script

17. Database Spy
 Once the execution in in Break mode, the Database Spy can help the user see:
 Locals: Local Variables values
 Stack Frame: Shows which VBScript interfaces are currently under Debug
mode
 Tasks Frame: shows the Runtime tasks states during the Break
