Installed Components Checker

Installed Components Checker

--------------------------------------------------------------------------------

Description : This script can detect installed components on your IIS.
Useful for people hosting at a provider's server where you often don't
know what's installed. No installation required, just download the script
and run it from your site. Currently it checks for more than 600
components and the component-list is always up-to-date because of central
list management. No need to download updates. Now with descriptions &
links. Check out the live demo at http://www.bier-voting.de/objcheck/

<%@ LANGUAGE="VBSCRIPT" %><%
'Due to the high number of components, the script may run into Timeout -
increase this value then.
Server.ScriptTimeOut=240

Response.Expires = 0

'History:
'v0.27 - Changed handling of different methods to get the list of
components from my server. Now the script
' will test every method until one is successfull, because i.e.
ServerXMLHTTP.4.0 seems to be buggy when
' behind a firewall or proxy.
'v0.26 - if there's no link yet available for a component, Google's
number one search result will be provided.
' Updated daily, thanks to Google for this great web service.
' - added support for more components for automatic update downloads and
proxy support.
' As I don't use proxies, I can't test the proxy support. Please give
me some feedback on this.
' If you need to use a proxy, enter the proxy information below (line
55,56,57).
'v0.25 - added descriptions and links for components, now you'll get a
short description of the components
' as well as a link to both the authors of the component and google.
' - you can now edit descriptions and links if there's none yet
available.
' - enter your own new components! click on "Add new component"
' - all new descriptions/links/components will be reviewed before going
online.
' - changed some colors
'v0.24 - changed method for automatic updates to XML-Stream
'v0.23 - added detection for misspelled or incomplete ProgIDs
'v0.221 - this script is now under the GPL, see licence.txt
'v0.22 - added link to Google when a component is installed, so you can
get a little bit more
' information on how to work with it.
'v0.21 - added check for URLs in the input box, because people always
enter their URLs instead of
' downloading the script...
'v0.2 - fixed some bugs, now first display information, then try to fetch
the list. Sometimes
' the XMLHTTP-Object doesn't work, maybe due to high traffic on my site.
Should work on your site.
'v0.1 - inital release January 2002

'Set proxy here
ProxyAddress=""
proxyusername=""
proxypassword=""

'This is the current version. These values are used for update-checking
and to tell the list-server
'how to react, will be checked later.
