VISUAL EXPERT FEATURES
7. Does Visual Expert work on VBA application
?
Not for the moment, Visual Expert will probably support
VBA in the future.
8. Does Visual Expert work with VB.net ?
The current version of Visual Expert supports VB5 to VB6, Visual Basic.net
will be supported in the future.
9. Does Visual Expert support Visual SourceSafe
?
No Visual Expert does not support this product. However there is no
conflict between these tools.
10. Which versions of Visual Basic are supported
?
All applications developed with Visual Basic versions 5 to 6.
11. Does Visual Expert work with Jaguar
(or EA Server)?
VE analyzes the PB code, no matter if this code is executed on the
client seat or on a Jaguar server.
12. Is there a maximum size for the application
to run Visual Expert ?
There is no limitation for your project. Application
of any size (Visual Expert can analyse hundreds of Visual Basic components.
Visual Expert includes powerful source code parsers. The duration of
the analyse depends on the size of your application.
Top
13. Is the analysis of the application fast ?
You can test on your station the analysis of the sample
application which contains approximately 12 Mb of code. The analysis
usually takes less than one minute.
14. Does Visual Expert analyse every object libraries
or ActiveX used in Visual Basic projects?
Yes, Visual Expert analyzes any object libraries or
ActiveX used in Visual Basic project.
15. Is it necessary to have comments in the application
so that VE can extract interesting information?
The main part of the information extracted by VE and useful for the
developer results from the application code.
If comments exist in the application, they will enrich the data provided
by VE.
If there's no comment, VE remains useful to analyze and help to understand
the code.
16.Can VE analyze a large application?
- Is there a limit (number of PBL, MBytes)?
There is no limit. Some of our customers have applications
which contain more than 250 Mb of PBL (several hundreds of PBL).
17. With VE, can we directly
modify the source code?
We bly recommend to use PB to make any code modification.
PB is the only tool able to manage the integrity of its own code (otherwise,
you risk to compromise your PBL and be unable to open them with PB).
For this reason, VE does not modify the code directly. But VE allows
you to locate the code: from any selected component, VE indicates to
you the PBL, object, control, and method... to open (in PB) in order
to modify it.
18. If the application is modified, how does
VE take it into account?
It is enough to refresh the analysis. It will be updated
in few minutes.
In the main menu, select "Tools" then "Refresh Code Analysis".
VE takes into account the modifications.
Top
19. To see whether a modification (in the PB
app) was taken into account by VE, do we have to close and relaunch VE?
It is not necessary to close and relaunch VE. Just select "Tools"
and then "Refresh Codes Analysis.
20. Which languages will be analyzed in the next
versions of VE?
We are currently working on the version supporting .NET.
Other languages are planned for the future.
21. With which PB versions is Visual Expert currently
compatible?
VE analyzes from PB4 to PB9.
22. Is VE compatible with PB9?
VE is compatible with PB9. (We were PB9 beta-testers).
VE is also included in the "PB CD Partner" that is delivered
with PB9.
Top
23. Is VE supported by all Windows versions?
VE supports Windows 98, ME, MT4, 2000 and XT.
24. Does VE provide "Version comparison"
features?
Not for the moment.It allows today to save the image
of a project and thus to historize several versions of a project. You
can thus consult the former version of your application even if the
source code is not available any more.
25. Does VE analyze stored procedures?
VE is not connected to the database. VE analyzes the
PB code, and also all the calls to stored procedures. You can thus know
the impacts of a modification of a stored procedure on the PB application.
If you have exported your stored procedures, you can include this export
in VE's project. The stored procedures are taken into account when doing
textual searches.
26. Is Visual Expert only available in English?
Today, VE is available in several languages : French, English, Spanish
27. Can we see the recursive references on several
elements?
Recursives means when a "function 1" calls a "function
2" and this latter calls again the "function 1".
We can see themt when we search for an element (object or attribute).
For example: In the "PowerBuilder Components" list, select
"Window" and click on "Window list".
Select the window "pfc_w_about" and click on "Functions
& events". Select the "of_getclosestatus" function
and select "Calling Hierarchy".
"Recursive call !" is displayed in red.
NB: VE does not offer any function to visualize at once all the recursive
elements.
Top
28. Does VE preserve your previous
PB versions? - After a modification of the application, does VE keep somewhere
a trace of the old PB code?
No. There are other specific tools to save previous versions of an
application.
29. When searching for a word
in the source code (using the "find" field), the required word
appears highlighted in red or in pink. Is there a code of colour for the
highlighting?
There's no color code.
Only the first selected word is in red, whereas the other occurrences
are in pink.
When selecting the 2nd occurrence, it will become red and the first
one will appear pink.
30. Can we change the presentation of technical
documentation?
You need to buy a separate module, called Cortex.
But to customize the documentation generated by VE, a Wizard offers
you many different options.
31. In which language was developed VE?
VE was mainly developed with C++ and a bit with PB.
Top
32. Is VE current version multilingual?
- Does the same VE version propose all the available languages?
During the installation, VE recognizes the language
of your station. And therefore automatically installs the corresponding
language. However, one option enables you to change language (French,
English, Spanish). But the documentation templates are only in English.
33. Following a modification
done on the PB app, when we refresh the analysis done by VE, are the customized
views (previously created) preserved and refreshed? - Do they take the
modifications into account?
When you refresh the analysis of VE, all the views previously created
disappear (since we cannot plan if the modifications are to be taken
into account in the created views). Only the Treeview (in the Mainview)
displays the changes carried out
34. After one search, is it possible
to perform new requests (impact analysis, inheritance...) directly on
the result of this search?
To work on the result of your search, you must first create a new
view (by clicking on "Save view" + "Save results").
A new tab will be created next to the "Main View" tab.
You can perform any request on this new tab.
35. How do the VE licences work? - Can a license
be installed on several seats?
One VE Licence can be only installed on one station (as PB).
There is not concept of "simultaneous users" or "concurrent
users".
Top
36. Is it possible to open 2 sessions of VE at
the same time?
No
37. Is it possible to analyse 2 different applications
at the same time?
No
38. Are there any technical skills required to
use Visual Expert ?
Visual Expert is very easy to install and to use for
any VB developer. No specific skills are required, except the basic
knowledge of Visual Basic itself.
REFERENCED BUGS
39. How can I obtain a correct preview of my
Forms ?
To obtain a correct preview VB6 must be installed on
your computer. Each graphic components (OCX, ActiveX) must be installed
and correctly registered on your computer. The form must not contain
UserControl. The type of the form must be Form but not MDIForm.
40. When I try to get a preview
of a form, it says " Application Error: The exception Integer division
by zero".
This problem occurs if you had custom tabs on your
toolbox in Visual Basic. This bug of Visual Basic is refernced by Microsoft.
If you want to fix this problem, you can read the article Q194753 at
this address: http://support.microsoft.com/default.aspx?scid=kb;EN-US;q194753
41. Visual Expert identified functions as unused,
but they are not.
Dead code includes functions, properties, parameters
or variables for which Visual-Expert does not find any reference. However,
an incomplete analysis, because of a missing component or a syntax error,
can provoque a lack of references and cause a wrong dead code.
OTHERS
42. Is there potential for hackers to gain access
to my system, via your program ?
Once installed on your desktop, Visual Expert does
not send us any information. Visual Expert will analyze your application
to provide you with help and services. The result will be stored on
your desktop. You are the only person to decide how to use it
