Editor's note: This is the first of a continuing interactive series on scripting that will appear on SearchWinSystems.com on a regular basis. Christa Anderson, a noted authority on the subject, will explain basic scripting concepts and then move on to teach you how to use VBScript to perform common tasks. You can e-mail your questions to firstname.lastname@example.org.
You get to objects through the scripting host. A scripting host is the operating environment for a script. Windows doesn't understand VBScript -- it needs an interpreter.
When Windows encounters a file with a recognized scripting extension, the OS passes the script to the scripting host. The scripting host interprets the script, then passes the script's message to Windows for execution. A scripting host doesn't understand all scripts; it understands only the ones written in languages -- script engines -- that the host supports.
Windows has two scripting hosts: Microsoft Internet Explorer (MSIE) and Windows Scripting Host (WSH). This column will focus on WSH and the VBScript script engine.
