Product overview

This component provides a way to store application settings in the Windows registry and restore those settings later. This component does not provide an access to the whole registry but to its limited part where application settings can be stored.

Features

Basically, you can do following:
= store application settings in the specific part of the Windows registry
= restore settings from the registry
= enumerate all settings in the given section of the registry
= delete settings from the registry

Functions

To create an instance in VBScript: CreateObject( "AbyssLabs.Settings" )

Save( application_name, section_name, key_name, value ) - saves a value

Read( application_name, section_name, key_name [, default_value] ) - restores a value

AllNames( application_name, section_name ) - returns a collection of all key names of the specified section

Delete( application_name, section_name [, key_name] ) - deletes a single key or whole section

Notes

Using this component, you have not any chance to deal with the registry "outside of" HKEY_CURRENT_USER\Software\VB and VBA Program Settings.

This component has Apartment threading model. For ASP/IIS programmers that means following:
= this component can be created in page, session, and application scope
= in an application scope only <OBJECT ...> notation can be used
= the page scope is highly recommended due to lack of performance in other cases

In such NT-based operating systems as Windows NT/2000/XP, each user profile has its own isolated part of the registry referred by HKEY_CURRENT_USER. That means that application settings which were stored by one user, can not be available for second one.

Especially for IIS users: by default, IIS runs under SYSTEM account but not under Administrator or under an account of somebody else.

Just in case: this component provides an access to the local registry only. Do not try to read the remote computer registry - it does not work.

Documentation and Sample code

Following files are provided:
= readme.txt containing a programmer's manual for this component
= some sample scripts written in VBScript are available in the Installation path\Tests folder

Installation procedure

The installation package contains a usual installation program that installs the component itself, all required libraries, and documentation files. A default installation folder is C:\Program files\AbyssLabs\Settings.
