 How-To:
Several articles which describe the ALP basics. They cover
some of the most interesting areas and can be read as a short ALP tour
by developers who meet with ALP for the first time. See the How-To
pages.
ALP includes installer
which can be used to install your application bundled with ALP engine.
It is designed for unattended installations which require only
confirmation from the user.
ALP ships with ALPFrame - special
ALP browser which extends the DHTML object model and most importantly
allows ALP to run from removable media - e.g. from autorun
CD or a Flash drive or memory card without installation on
the PC (there are some limitations about how and which components can be
used). Read

Development samples.
Wide range of samples is included in the ALP download
for developers. Additional examples are published on this
page as they become available. The examples on that page are most
often a result of questions asked by developers.
 Latest
documentation. The ALP download
for developers includes NDL (newObjects Development Library) which is a
combined documentation for all our products and components. However the
library is updated more often than any of the products referred in it.
You can download the latest NDL
from our site.
 The
ALP Run-time library. It is a set of components that can be
used through the ASP compatible programming interface supported by ALP.
The library is also available separately as newObjects
ActiveX Pack1 family. It can be installed on any Windows machine to
bring there the ALP Run-time library features even for non-ALP
applications. This makes any effort made to learn and implement code in
your ALP application with its run-time library portable to other
environments and scenarios - such as IIS, VB and so on. In it you can
find components such as:
SQLite COM - Zero
configuration, lightweight SQL Database engine. See the component's
page.
NetStreams which
brings the TCP/IP and IRDA networking in form compatible with the file
management components.
Storages and files
components - Several components that form together a strong hierarchy
which allows you access the file system, memory blocks, OLE storages,
network connections through a single programming API.
Background thread management
- you can run scripts in background threads asynchronously.
Example deployment packages.
Several dummy ALP applications packed with the ALP Installer or
configured for autorun with ALPFrame browser. The examples cover the
most popular distribution scenarios and allow the developer see what and
how must be packed together. Use them as a start point for your custom
deployment solutions. Go to deployment
examples page.
 Wonder
what's the difference between ALP and PWS? While Microsoft's
Personal Web Server (PWS) is a WEB server ALP is not. You cannot pack
PWS as part of your application or run it from a CD or a flash card
without installation. On contrary ALP's programming interface is similar
to PWS, but it can be packed with your application, run on-the-fly from
a removable media, all the configuration your application needs can be
packed with it so that the end-user would not need to do anything but
run the application. Read

 Compatibility
FAQ. The WEB developers who examine ALP often wonder if they
can continue use certain client-side plug-in and controls (Java,
Macromedia etc.). Although these browser enhancements are built for HTTP
usage they can be used in ALP with some limitations. This FAQ
page contains the most often asked questions and answers about them.
ALP General errors reference. The
list of the general ALP engine error messages. These messages are issued
by the ALP engine and are not specific to a particular programming
interface. When such a message is shown to the user it is an indication
of a configuration mistake, violation of a protection rule, wrong link
and so on. Tracing bugs identified in your application by an end-user
will most often begin with a report for one of these messages. The error
messages list will give you information about the possible causes of
each message.
 Licensing
ALP is a programming platform not a product directing the end-users
in a single step. Applications written for ALP need to redistribute the
ALP engine or alternatively they need to tell the user to download ALP
separately. With the ALP licensing policies we give the developers
freedom to buy once and use the ALP for unlimited number of projects
without hidden costs. Read

Developer highlights:
WEB-like desktop application environment
Active Server Pages compatible programming
interface. Supports VBScript and JScript, can be configured to
use any other Active Script compliant language (such as Active Perl).
All the core ASP objects: Request, Response,
Server, Application, Session and powerful Run-Time library 
Include directives - file and virtual
Virtual sites structure and settings,
ALP Application settings (similar to ASP Applications in classic ASP).
Structure is defined with files in the physical directory tree. (ALP
URL , Server.MapPath
)
global.asa - Application initialization
script with events and scoped objects
CGI support (Common Gateway
Interface)
Directory view plug-in - lists directory as WEB page (as like IIS). With
templates support.
Simple HTML templates - HTML page with special tags is filled
automatically from the request. (read
more )
With ALPFrame - extended DHTML
model - window menus and shortcut menus are controlled by the pages
currently opened. (read
more )
Install utility - components and
sets of other files can be configured in the setup configuration and
deployed easily. (read
more )
What can be done with ALP:
- Write desktop application in ASP (VBScript, JScript
and so on). Use existing WEB server programming skills, code and
developers to build client side software.
- Port certain ASP applications for the desktop or even
autorun applications.
- Run CGI programs as well.
- Embed IE browser in VB/C++/Delphi applications and use
ALP to generate content for the hosted browser.
- Develop business applications with minimal
efforts and run them on both Server and stand alone machines
as appropriate.
- Create/Port active WEB sites for offline usage with
all the dynamic functionality kept.
- Create applications with extremely minimized dependencies.
- Create flexible integrated or teared-off applications for your
IT infrastructure.
Version history
ALP 1.2:
- Helper mechanisms for application
protection.
- Configurable browsing restrictions
in ALPFrame
- All the core modules are now in the core
ALP DLL.

- independent zero-configuration SQL
database engine
- TCP/IP and IRDA components
- Powerful String formatting tools
- More convenient thread objects
- Synchronization objects
- Improved ALPFrame behavior -
copy/paste default support, Windows XP SP2 security features
detection and registration with the system.
- Content zone - The ALP local
content can be declared as part of an online site and full
compatibility with the XP SP2 security features.
- Improved support for composite objects
written especially for ASP usage.
ALP 1.1:
- Uploads (Request.BinaryRead)
