VB RezQ
Frequently asked questions about VB RezQ
|
|
When I buy VB RezQ do I get a code to unlock the demo
version?
The full version is separate download, not an upgrade of the demo
version.
I would like to purchase VB RezQ, but I don't have a credit
card. How can I buy it? I would also like to know the price in
Euro's.
All purchases of VB RezQ are handled by RegNow (by using the 'buy'
button on our 'Buy Now' page).
You can buy online from RegNow with various credit cards and PayPal, but they
can also support sales by 'phone, fax and mail and other payment

on the online ordering form. RegNow can also show you the price in a
number of currencies including Euro's.
See the FAQ at RegNow for
more details.
How is the VB RezQ software delivered when I purchase it?
Delivery of VB RezQ is by download from RegNow's servers.
On successful completion of payment to RegNow you will receive an
email from RegNow with a personal link from where VB RezQ can be
downloaded and a personal registration code.
Does the full version recover more than the demo version does?
The demo version is restricted to recovery for only one source
file. What it recovers from that file is exactly the same as the full
version will recover.
Does VB RezQ recover Modules and Classes, or only Forms?
VB RezQ recovers data for Modules and Classes as well as for Forms
and all other types - UserControls, UserDocuments, PropertyPages,
Designers - to produce a full set of files that will open as a
project in the VB IDE. More data is recovered for files with GUI
elements than those without. A more detailed description of what
VB RezQ can recover is available
here, and our
example shows the output VB RezQ
produces.
Does VB RezQ recover the whole code source?
VB RezQ recovers much of the structure of the program including the
GUI elements (form design etc) and the headers for subroutines. It
does not recover the actual Visual Basic language code within the
subroutines. A more detailed description of what VB RezQ can recover
is available
here.
Do you have a version of VB RezQ that is capable of recovering
the whole source code?
We don't have any other version that recovers more of the source code.
Why does VB RezQ not recover the actual Visual Basic code within
the subroutines?
When VB source is compiled to Native Code the result is x86 machine
code and in the process the VB compiler with its various code
optimisation features erases much of the structure of the high level
Basic language. It's a formidable job to try to reverse engineer this
x86 code back into VB code and it's not at all clear to us that it's
possible to automate the reversing process.
Do you expect the capability to recover the source code within
subroutines will be added to VB RezQ?
We don't expect to add recovery of the source code within subroutines.
VB RezQ can show you a disassembly of the x86 code and you
can see how far removed from VB code it is.
Are there other software tools that can recover the subroutine
code?
For projects compiled to Native code, we are not aware of any tool
that will get back the Basic source of the subroutines from the x86
code. We don't expect to ever see one as explained above.
For projects compiled to P-code, there are claims made that tools exist
that will recover some Basic source from the P-code. None of these
is made available to others as far as we know, but it's possible they
may be one day.
Does VB RezQ only recover from Visual Basic or Visual C++ also?
It only works with files compiled by VB, not VC++ or any other language.
Do you know if programs exist to recover from an .exe compiled with
C++?
We only look at recovery from VB files and don't have any knowledge
of what tools exist for other languages.
