Visual DataFlex
12 is a complete application
development tool for Windows and Web environments, and is known for
being one of the most powerful database application development tools in
the industry. Visual DataFlex is specifically designed for the purpose
of building client/server database applications - fast.
Visual
DataFlex's integrated
Web Application Server technology delivers
dynamic, fast, secure, web-enabled database applications utilizing
Windows Server technology. Visual DataFlex Studio's web application wizards and
other rapid development facilities seamlessly build ASP and business
logic code for creating database-enabled Web applications. The Web
Application Server is the business logic engine and deployment tool, for
controlling intelligent database integration and centralized business
rule and process execution.
As an
added extra, Visual DataFlex
12 also includes a complete application for
Web content management -
Electos! Electos is a perfect choice to
accompany Visual DataFlex
12. Electos is immediately useful to
end-users, and it opens a wide range of opportunities for Visual
DataFlex developers
to integrate the system with their own applications to create exciting
new Internet solutions.


Visual
DataFlex Developers in Asia Pacific now also receive a FREE
license of the newly released
FlexODBC Version 4 with their
Visual DataFlex 12
Studio and subscription renewals, valued at A$467.50!!!
FlexODBC is an ODBC driver (DLL)
for the DataFlex Embedded DBMS. This driver allows any ODBC compliant
front end application to read and write data contained Visual DataFlex
applications. A user in Microsoft Office can use Excel to pull company
accounting or invoice information directly into a spreadsheet and create
a chart. Microsoft Word users can do a customer mail merge directly from
DataFlex files. Crystal Reports users can create multi-file reports from
DataFlex data. Microsoft Access or Borland Delphi can even be used to
merge DataFlex data with other data sources to produce complex reports,
or to run mass file updates based on multiple criteria.

Visual DataFlex
12 Studio 30
Day Evaluation
A ready-to-install, Visual DataFlex
12 Studio 30 Day Evaluation is
available to application developers. The Evaluation has no limitations
other than a splash screen and will automatically expire and cease to
operate 30 days following installation on a given computer system.
Specific terms and conditions of use are defined in the License
Agreement. A Visual DataFlex
12 Studio 30 Day Evaluation
can be “activated in place” to enable a developer to use the Studio
without re-installation.
Once
you've installed Visual DataFlex
12, the best way to quickly acquaint
yourself with application development using Visual DataFlex is to get
started by reading the Web Application Quick Start and
Windows
Application Quick Start sections in the Visual DataFlex Help system.

VDFQuery 2.3 (VDFQuery.doc)
VDFQuery is a query tool meant to be integrated into your Visual
DataFlex
application. You may also decide to compile VDFQuery as a stand-alone
program. To do that you should compile dbquery.src. |
 |
FastView 10 (FastView.doc)
The FastView program is an alternative to dbExplorer and may be used to
view and change the data in your tables. But it is more than that. You
may compile your DataDictionary classes into the FastView program
thereby making all updates to your database obey your business rules.
Read about it in FastView.doc |

VDFGraph 1.4 (VDFGraph.doc)
VDFGraph is a collection of tools for drawing graphics on the screen.
You may compile grdemo.src for a demo of what the routines can do. |

DFmatrix 10 for VDF10/11 and DataFlex 3.2 (Dfm.doc)
DFMatrix is a collection of VDF/DF tools. Read Dfm.doc for further
information. |
 |
DBQuery.df3 is a stand-alone query program for
DF 3.2 (DOS, Unix, Linux) |
Things to note about this release :-
The packages included do not handle tables the new RowID way. This means
that they will function with "Recnum-enabled tables" which at the time
of writing translates into 100.0% of the applications out there.
"Standard tables" (tables without recnum support, the new way) can not
be handled at this point. Of course this must be fixed some time.
Secondly, everywhere in the packages and the documentation, when
references are made to "arrays", we are talking about the array object
and not the array type that has been implemented as of Visual DataFlex 11.
The packages in the VDFQuery upload available here were programmed by
Sture Andersen and are to be considered 'public domain'
and may be distributed freely as is or as part of a product including
these files with no further permission other than this statement. We
only request that developers do not attempt to back-port VDFQuery to
VDF/DF versions earlier than the versions it was intended for by Sture
Andersen.
This is new in VDFQuery 2.3 compared to 2.2b (August 2004) :-
