Daniel Devolder and updateStage, inc. are happy to announce the
release
of vList Xtra. vList Xtra saves and retrieves Lingo lists and other
data
types in binary format using either an external file or a cast member
for
storage. Lists are a powerful and fast way to manage all kinds of
information in Director. Since lists can hold Director`s rich media
and
data types they are the natural solution for creating Director
databases,
yet few developers use them this way. Why? Because saving and
retrieving
lists at runtime using Director`s built-in string() and value()
methods
is slow and limited.
vList Xtra offers the following advantages over Director`s own list
saving methods:
* RELIABILITY: vList correctly retrieves lists regardless of the data
content. Director`s value() function is tripped up by certain list
content and may not be able to rebuild a list saved as a string.
* STRONG ENCRYPTION: vList Xtra offers optional encryption of a stored
list using AES (Advanced Encryption Standard) encryption , the
standard
for secret-key encrypted transfer of unclassified information recently
adopted by NIST, the US National Institute of Standards, as a
replacement
for DES. Encryption can protect sensitive data as well as cast member
media that is expensive to produce such as the new 3D cast members in
Director 8.5.
* INTERNET FEATURES: vList can save data to the user`s local drive
from
Shockwave , convert data to Base64 strings for transmission to web
servers using postNetText, and it can load vList files from the local
hard drive or from remote URL`s using preloadnetthing.
* PERFORMANCE: vList, unlike Director`s value() function, preserves
the
sorted state of a saved list when it is retrieved, eliminating the
time
hit to do a resort upon restoration of the list, and therefore greatly
speeding up any subsequent search of the list
* FLEXIBILITY: vList Xtra was designed to store lists, but you can use
a
vList file or vList member to store any supported data type without
first
writing it to a list.
* MORE DATA TYPES: vList can read and write the following data types,
which are not supported by the Lingo value command:
member.media
member.picture
image (Director 8 and above)
transform (Director 8.5 and above)
void
The media property of a member saved by vList is completely
independent
of the cast member it came from. You can use this feature to extract
members from one movie and recreate them in another.
* SIZE: The list size vList can work with is limited only by available
memory. Director`s value() function is limited to 32,767 entries for a
linear list and 16,383 for a property list
* BINARY FORMAT: vList saves lists and other data types in their
native
binary format rather than converting them to and from text. Since no
conversion of the data is necessary, vList is up to 20 times faster
than
Director`s value() method, allows lists to be retrieved in a sorted
state, and preserves floating point numbers to their full precision.
In addition to saving and retrieving lists and other data types, vList
offers several new commands for managing lists.
* aList = concatenate (list1, list2, .., listN)
* sortedState = sortP (aList)
* unSort (aList)
* setPropAt (aPropList, index, property)
* insertAt (aList, index, value)
* insertPropAt (aPropList, index, property, value)
* appendProp (aPropList, property, value)

> PRICING
--------------------------------------------------
There are three registration options:
Limited free
Basic $149
Full $299
LIMITED
*******
In Limited mode a small set of vList commands are free to use and do
not
display a demonstration dialog. The free commands allow you to save a
list to a file and retrieve it in authoring and from a projector but
not
in Shockwave.
BASIC
*****
Basic registration unlocks all of the vList commands and
capabilities
except for encryption. Under basic registration you can:
- Create and use members for list storage
- Access vList`s extended Lingo list management commands such as
concatenate, insertAt, sortP etc.
- Read and save lists to local external files in Shockwave, or
MIMEBase64 encode them for transmission using postNetText
- Read vList files downloaded to the internet cache
FULL
****
Full registration unlocks encryption.
