Xbase++
The current version of Xbase++ comes
with quite a few new features we have added upon customer
request. The painful times of printer configuration are over
due to a new XbpPrintDialog() and a revised XbpPrinter() class,
for example. Now you get transparent access to the standard
Windows printer dialog or the properties of the printer driver.
The SDFDBE and DELDBE are completely revised for Clipper compatible
SDF and DEL import/export formats. Multi-threaded programs
benefit from a revision of all SET commands. More than a dozen
SET settings received thread-local scope allowing for better
encapsulation of multi-threaded programs.
More than a dozen new functions are added making a programmer's
life easier. Is the Shift key pressed when a left click occurs?
How many PRIVATE variables are declared? Which exported functions
are available in a dynamically loaded DLL? What is the PRG
source code of a code block? These are a few questions that
can be answered now with a simple function call.
Besides of new features, hundreds of PDRs have been closed
in Xbase++ and we are going to use this version ourselves
for building the Alaska Software Developers Portal on our
home page.

XbToolsIII
This new version focuses solely on bug
fixes. |

Web Application Adaptor
We concentrated on useability and reliability
for the new WAA version. A major benefit comes from thread-local
scope of SET settings in Xbase++ which allow two Web applications
to use different character sets or date formats independently
from each other, for example. The TCP/IP implementation is re-worked
and user-defined error messages are possible. |

Profiler for Xbase++
Speed, Speed, Speed! Many customers of
Alaska Software have asked how to optimize the performance of
their applications. Although we invest continuously into performance
improvements of Xbase++, we want you to be able to analyze and
optimize your own code. Therefore, we have invested in a profiling
tool that allows you to trace all function, procedure and method
calls of your Xbase++ application, no matter if they were written
by yourself or by Alaska Software. You can trace things like:
What parameters are passed? How often is a function called?
How much time is consumed in total by a particular function?
Even if speed is not your primary goal, the Xbase++ Profiler
can help you in understanding the program flow of huge and complex
applications. |

OpenGL for Xbase++
Have you ever seen these great 3D animations
on TV and wondered how this can be done? Do it with Xbase++!
A class derived from XbpStatic encapsulates an OpenGL interface
and does the job for you. It gives you access to the 3D rendering
engine. An example program showing business graphics is included. |

Pre-processor API
You are fond of the Xbase++ pre-processor
and want to use its abilities in your programs? Go ahead! We
have added an example program demonstrating how to dynamically
load the pre-processor DLL and access the pre-processor API
of Xbase++ with DLL-FUNCTION. Build your own command-line interpreter
or boost your data-driven programs with the "secrets" of the
pre-processor API. |

KnowledgeBase
Currently, this is a collection of documents
in HTML, PDF or MS Word DOC format focusing on Alaska Software
products and technologies. They cover technical details, explain
how things are working inside of Xbase++, describe what technologies
are in development or deal with other Xbase++ related issues.
Each developer at Alaska Software is committed to write at least
one paper per subscription. So stay tuned and watch this collection
of technical articles growing over time. |

ADS Database Engine
The ADSDBE integrates better into the
Data Access Chain technology of Xbase++ and received PDR fixes.
Also, an enhanced session management is included due to customer
request. |

ODBC SQL Database Engine
Since its early beginning, Alaska Software
has promised to deliver native SQL access. Software developers
know that "to finish a software" usually takes more time than
anticipated, but sometimes things take longer than anybody would
have ever assumed. However, the ODBC DBE is ready. It demonstrates
how seamlessly other data sources, like SQL or MS Access, for
example, can be integrated into your Xbase++ application. This
DBE also gives you some inside knowledge about the Data Access
Chain technology and how you can prepare yourself today for
seamlessly switching between DBF and SQL Database Engines tomorrow. |

HTML Reflection Framework
The HRF is an implementation of the DOM
standard from the W3C consortium and fully supports HTML 4.
The HRF class framework eases the pain when applications are
deployed in the Internet and cryptic HTML code is mixed with
your business logic written as PRG code. With HRF, a HTML file
can be loaded into an Xbase++ application and filled with data
originating from a database file, for example, by calling methods
of HRF objects. The modified HTML file can then be written back
to disk or sent to the Internet. |

Active Xbase++ Scripting
Engine
Scripting technologies are hot in these
days! Just think about Perl, JavaScript or VBScript. The Xbase++
Scripting Engine enables you to write your script code in your
favorite language - Xbase++! Future versions of the Scripting
Engine will support Linux, Windows Scripting Host and more.
Get in touch today with the technologies that will drive your
success of tomorrow. |

Sourcecode for XbpBrowse(), XbpQuickBrowse()
This Xbase++ source code gives you an
insider's knowledge of how to code Xbase Parts to their limits.
We publish the PRG code of the two browser classes along with
an example of how to implement a "Sorting Browser" based on
XbpQuickBrowse() that supports sorting and sizing of single
columns. |

XML for Xbase++
XML is a future technology for distributed
applications, but only few programmers are using it today. A
major hurdle in the acceptance of XML is the necessity of having
an XML parser. To pave the path for your XML usage, we have
developed a non-validating XML parser engine for Xbase++. It
is easy to use from your PRG code and lightning fast, since
it is entirely written in C. We have added a sample application
using XML to describe input data, and a DAC database sample
demonstrating how to create XML data from your database and
access it using latest MS Internet Explorer 5.0 XMLDSO technology. |
