M/S Scripting DocumentationAE6382
The most difficult aspect of scripting in Windows is finding the documentation.
Microsoft produces enormous quantities of documentation for its part – it is a matter of locating the correct document and interpreting it.
The documentation for non-Microsoft software can be difficult.
MS Documentation
Local copies of some of the MS scripting documents are located at
Windows Scripting Host
The Windows Scripting Host provides an environment for running scripts in Windows.
Provides a host for ActiveX scripting engines (VBScript, Jscript, and other 3rd party implementations)
The fundamental object is WScript and is pre-instantiated
Windows Scripting Host
The WshShell object makes it possible to run a program locally.
Can control the programs input and output
The WshScriptExec object is returned from the Exec method and contains status information
Runtime Scripting
The Runtime Scripting component provides capabilities for VBScript and Jscript that are not otherwise available. They cannot be use when scripting a web page in IE.
The objects included in the Runtime Scripting are
Dictionary (associative arrays)
File System Object
MS Office Objects
The objects available for the Office programs (Excel in this case) are located on the Office CD in the form of .chm (MS Help files).
The file for Excel 10 is VBAXL10.CHM
This file contains all the objects and their methods and properties.
The objects documented here can be used either by VBA within Excel or accessed externally via automation of the Excel program.
For more information see
Automation of Excel Example
An application that uses data stored in an Excel worksheet to generate a configuration file for use by a Linux dhcp server.
The Excel file contains IP address, MAC address, location, owner, and information about whether address is to be managed by dhcp.
A script file uses automation to access the fields in the Excel file then generates a Linux formatted text file.
my $excel_file = 'e:\programming\ruby\dhcp_sample.xls';
It can be downloaded from
It is not using the Windows Scripting Host it is standalone.
The Win32::OLE modules that are loaded via the use statements provide the automation support.
See the ActivePerl documentation for more details.
