eUpdator Component Reference

ProductKey is a unique identifier for your Application. This will be the name of the keys that eUpdator uses to identify this application. Make sure you use an identifier that cannot be mixed up with another product. For example you could use your company name in combination with the application name as a product key.

You should never change this key in an upgrade of your application since eUpdator will treat it as a separate application.

Top

Destroy method

destructor Destroy;

Calling execute from your application will start the eUpdator component. eUpdator searches for the update file and checks if there is a new version available. If there is an update available the eUpdator Application will be launched and the update will be collected. If the eUpdator Application is not installed the first thing the eUpdator component does is to download and install it from the internet.

TLanguages

type TLanguages = ( lgEnglish, lgSwedish );

There are currently two different languages supported by the eUpdator system. We are planning to support more languages in the future, i.e. Spanish, French and German. If you want to support us by translating the software, please contact info@elysian.nu.

INI-files Entries

Earlier versions of the eUpdator registered itself in registry. Due to problems with different rights to the system, we gave up that idea. Using the registry was unnecessary cumbersome.

On execution the eUpdator component automatically registers itself in the eUpdator.ini file located in the Windows directory. This enables the eUpdator Application to find and make updates. A section with the same name as you have specified in the productKey property will be added in the eUpdator.ini file:

Following values are registered under your <ProductKey> section:

Application	Application property
Language	Language property
Path	Path of your application
ProductKey	ProductKey property
UpdateFile	UpdateFile property
Version	Version property

eUpdator Information Files

eUpdator uses information files to determine if there is a new version available. Information files are built like a INI-file with sections for each productKey you want the file to support. First you add a section named '[<ProductKey>]' to the file. Following the section is the version information and source where to find the update. The two values are separated by the <TAB> character and may be put inside quotation marks. Source may be located on an ftp, http server or your local network and must be specified as a complete URL. Here is an example of the eUpdator.inf file used on the Elysian Homepage.

[Elysian eUpdator]
"1.0.2.130" "http://www.elysian.nu/eupdator/download/eUpdator.exe"
