No InduSoft Web Studio v7.1 + SP2, foram introduzidas novas ferramentas para a depuração do VBScript em projetos do InduSoft. As novas ferramentas incluem code-stepping, break-points, e uma lista de váriaveis a serem observadas para aumentar ainda mais a produtividade e precisão quando utilizando VBScript no InduSoft Web Studio. Participe com a InduSoft de uma demonstração dessas ferramentas e aprimore o seu projeto!

4. 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

5. 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!

** Global Procedures is a repository (library) of user-defined sub-routines and
functions, which can be called from any VBScript interface in the project. It is not an
execution module (thread) by itself.

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

12. Built-in $Trace() function
Output Window messages
VBScript MsgBox function
Error Handling with On Error Resume Next / On Error Goto 0

14. 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

15. 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.

16. 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

17. 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

18. 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
