Microsoft provides both Visual Basic® Scripting Edition (VBScript) and JScript® scripting engines with WSH. Microsoft anticipates that other software companies will provide ActiveX® scripting engines for other languages, such as Perl, TCL, REXX, and Python. WSH can be run from either the Windows-based host (Wscript.exe) or the command shell–based host (Cscript.exe). This paper describes:
Windows Script Host is integrated into Windows 98, Internet Information Server version 4.0, Windows 2000 Server, and Windows 2000 Professional. It is also available for the Windows 95 operating system. BENEFITS of THE Windows Script hostWindows Script Host (WSH) brings simple, powerful, and flexible scripting to the 32-bit Windows platform. Implementing More Powerful ScriptsPreviously, the only native scripting language supported by the Windows operating system was the MS-DOS® command language. Although it is fast and small, MS-DOS has limited features, compared to VBScript and JScript. Today, ActiveX scripting architecture allows users to take advantage of powerful scripting languages such as VBScript and JScript, and MS-DOS command scripts are still supported. Windows Scripting OptionsActiveX scripting architecture enables powerful scripting, using languages such as VBScript, JScript, and Perl. Microsoft currently provides three hosts for running these scripting languages across the Windows platform:
Internet Explorer enables scripts to be executed on client computers from within HTML pages. Internet Information Server now supports Active Server Pages, which enable scripts to be run on Web servers; in other words, it enables server-side scripting over the Internet or an intranet. Windows Script Host enables scripts to be executed directly on the Windows desktop or command console, without the need to embed those scripts in an HTML document. Scripts can be run directly from the desktop by clicking on a script file, or from the command console. WSH provides a low-memory scripting host that is ideal for non-interactive scripting needs, such as logon scripting, administrative scripting, and so on.
WSH InstallationYou must install Microsoft Internet Explorer version 3.0 or later to use Windows Script Host. WSH relies on the VBScript and JScript engines provided with Internet Explorer 3.0 or later. WSH is installed as part of the Windows 98 and Windows 2000 operating system family, and Internet Information Server 4.0. A separate setup program is provided for the Windows 95 operating system. Windows 95 Operating SystemTo install WSH on a Windows 95–based system, install Microsoft Internet Explorer version 3.0 or later if you have not already done so. If you do not have Internet Explorer 3.0 or later, see the Microsoft Internet Explorer Web page. Download WSH Setup from the Microsoft download site. Running Scripts Using the Command-based Scripting HostCscript.exe uses the following syntax: cscript [host options…] [script name] [script options]
Each parameter is optional; however, you cannot specify script parameters without specifying a script. If you do not specify parameters, Cscript.exe displays the Cscript.exe syntax and the valid host parameters. Cscript.exe supports the following host parameters:
WSH Command ExampleSeveral sample scripts are installed when you install WSH. The sample scripts are in the %windir%\WSamples folder (where %windir% is your Windows 95 or Windows 2000 folder). To run Chart.vbs
cscript //logo %windir%\wsamples\chart.vbs cscript //nologo %windir%\wsamples\chart.vbs Running Scripts Using Windows-based Script HostThere are three ways to run scripts in the Windows operating system, using WSH. You can:
When you run scripts from Wscript.exe, you can select the Always Use the Windows Script Host to open this file checkbox and set properties on the WSH Properties page. When you run a script and the Always Use the Windows Script Host to open this file checkbox is selected, Wscript.exe is registered as the default application to run files with the extension of the script you are running. For example, if you select the checkbox when you run Chart.vbs, Wscript.exe becomes the default application for all files with the .vbs extension. This checkbox functions identically to the Cscript.exe //C switch. The WSH Properties page provides the following options:
The Windows Script Host serves as a controller of ActiveX scripting engines, just as Microsoft Internet Explorer does. Because the scripting host is not a full Internet browser, it has smaller memory demands than Microsoft Internet Explorer; therefore, WSH is appropriate for performing simple, quick tasks. The scripting host reads and passes the specified script file contents to the registered script engine by the IActiveScriptParse::ParseScriptText method provided by the script engine. The scripting engine does not use the SCRIPT tag (used in HTML); instead, it relies on the extension of the file. Therefore, the script writer does not have to be familiar with the exact ProgID of various script engines. The scripting host maintains a mapping of the script extensions to ProgIDs and uses the Windows association model to launch the appropriate engine.
