Windows scripting engine 5.7 download

If you need files copied over to a remote machine for further use, then you'll have to write code to copy them yourself. The status of a WSH remote script can be represented by any of the values listed in Figure Compared to connecting to the events of the WshRemote object, the Status property gives you an inexpensive way to get status information. Connecting to events uses more computer resources and can sometimes be tricky.

This code shows how to run a remote script and monitor its progress:. Notice that the Status property of the WshRemote object is only updated when it is effectively queried, minimizing the traffic between calling and called scripts.

An alternative that uses events is shown in Figure If a remotely instantiated script terminates because of an error, the WshRemoteError object is filled with error properties such as Number, Description, Character, SourceText, and Source. You access this object through the WshRemote Error property, typically from within an event handler that catches the Error event.

It runs an application in a child command shell and provides access to streams of the spawned process like StdIn, StdOut, and StdErr. The Exec method takes a string value indicating the command line used to run the script. The command line should appear exactly as you would have typed it at the command prompt.

The Exec method returns a WshScriptExec object, which is the object that actually provides status and error information about the script being run.

You cannot use the Exec method to execute anything other than command-line console applications. Likewise, the Exec method cannot be used to run remote scripts and should not be confused with the Execute method of the WshRemote object. The WshScriptExec object solved an issue for script developers who needed to spawn console or command prompt applications.

A simple, yet effective approach is the following:. There is nothing wrong with this approach as long as it really provides what you need. The Run method ceases to be the ideal approach if you need to access the input, output, and error streams of the spawned application.

In this case, you are better off using the Exec method. The WshArguments object provides access to the entire collection of command-line parameters in the order they have been specified. WshArgument is a collection that can be accessed according to the typical programming interface of COM collections. Named arguments are command-line arguments that have been associated with a name. All arguments not associated with a name fall in the category of unnamed arguments.

The contents of the Arguments collection are always the sum of the contents of Named and Unnamed arguments. In general, a command-line argument includes two distinct types of information: the role and the value. For most applications, the role of each parameter is implied by the position it occupies on the command line.

The program assumes that the first parameter means one thing, the second another, and the third something else. The role of a named argument is not implied by position but comes as a part of the argument itself. Consider this command:. Scripts that define their command-line arguments according to this schema have a way to identify their input values by name. Named arguments are far easier to manipulate because they can be placed anywhere on the command line and are self-explanatory.

Any other combination of characters simply won't work. The value of the parameter is what comes after the colon until a blank character is found. If you want to assign it a string that may contain blanks, you must wrap it in quotes, like this:.

When a named argument is stored in the Named collection, the wrapping quotes, if any, are removed. All the named arguments are extracted from the command line, parsed, and made accessible through the Named collection. The following code returns the number of named arguments for the current script:. The Named collection provides the typical programming interface for collections.

This includes properties like Item, Count, and Length. In addition, Named has an extra method, Exists. The Exists method checks whether the collection contains an item whose name matches the specified text:. All the arguments on the command line that don't have a name are considered unnamed and grouped in the Unnamed collection.

You retrieve any unnamed argument as you would retrieve a generic item from Arguments. Script applications implemented through the WSH schema can include metadata, which is information used to request special services from the WSH runtime. In particular, all the information defined within the runtime element serves as self-documentation. It lets you specify the expected arguments, a description of the script's behavior, and usage information.

The runtime element is the parent element within which you define all run-time arguments and usage information. The runtime element is normally placed immediately following the job element. It is a child of a given job, and all of its settings apply only to that particular job:. The named element indicates one of the named arguments that a job supports.

It recognizes four attributes: Name, Helpstring, Required, and Type. The Name attribute, as you might guess, allows you to define an argument name. The Helpstring attribute specifies the description of the argument. The Required attribute is used to set an argument as required or optional.

Type is an optional attribute that describes the type of the argument. It determines how the argument will be parsed from the command line. Allowed values are "simple," "string," and "boolean," with "simple" being the default value. Figure 13 shows the elements you can use under the runtime element that influence the output of ShowUsage. The code in Figure 14 generates the message box shown in Figure Figure 15 WSH Options The run-time information for each parameter is used only for self-documentation and to format the data displayed by the ShowUsage method of the WshArguments collection.

The runtime elements do not enforce the values set for the arguments it contains. For example, if an argument is marked as required but is actually missing from the command line, no error will be raised. The list of enhancements in WSH 5. But before closing, let me mention a couple of tips that will help you when scripting for Windows XP. First is a visual issue. Windows XP has Visual Styles that can be turned on programmatically. All that's needed is an XML manifest file with the same name as the executable, with a.

Amazingly, the same XML manifest file can work unchanged with any executable on that machine, but you might want to customize the product and copyright information. However, turning themes on for all WSH applications is easy. In doing so, you'll notice that the System32 folder already contains a few other manifest files. The effect, with and without the manifest, is shown in Figure Password, implemented in the scriptpw.

Although this is not officially part of the WSH 5. The ScriptPW object works as a password reader and allows you to type in sensitive data without displaying it. The GetPassword method collects and returns the typed text.

You use the component as follows:. Password is certainly useful because it addresses functionality that was previously missing. Unfortunately, though, it is not perfect. For one thing, it doesn't work in a GUI environment and is only available to console scripts running under the control of cscript. Second, it captures any text you type but it never provides any feedback to the user.

In particular, it displays only a blinking cursor as you enter text; no special character replaces the individual characters. The WSH core wscript. In the past, a lot of people applied the same model to their applications making them customizable and extensible.

The question you may be asking now is what's going to change in this area with the advent of. Scripting has very little to do with. NET for two good reasons. Second, the advantages you get from. NET languages over scripting languages are substantial in terms of performance and programming ease.

Whenever you can use a. NET language instead, there's no question about what's better. These new engines are freely redistributable along with the rest of the framework. At this time, the two script engines that the. NET and JScript. In addition, a third engine is in the works for the. NET intermediate language IL. This engine would be able to load precompiled IL code but not compile from sources. This new Script for the. First, you have full access to the entire. NET platform. In other words, you are no longer forced to build a tailor-made object model in your applications just to allow for scripting.

NET, the application is inherently programmable in the sense that any constituent public class is accessible without intermediate proxies. However, you can control what objects are effectively reachable via script and you can make the scripts run in a kind of secured sandbox. The languages you use to script.

NET applications are the same first-class languages you use for writing them. They provide advanced features such as strong typing, early binding, and, of course, compiled code. In addition, Script for the. To start using a language engine, you first create an instance of it, add some code, and then add the object model that the script is based upon.

Objects are not attached to the engine through living instances as they were with the Windows Script engine. Instead, you need to specify the type and name in order to script the object. Only when the script executes and an instance of that object is needed will the engine call you back to obtain a usable instance for that kind of object.

The interface involved with the setup of the engine is IVsaEngine. The interface for callbacks is IVsaSite.

The language engines also support the ability to add references to. NET classes by creating an item in the engine with the full name of the involved assembly. In this way, all the types in the assembly are available to the script. When WSH is updated for. NET it is expected to be an application based on the Script for the. What you can expect in the future of WSH, far beyond today's upgrade, is a shell-level environment that knows how to work with any.

NET language from JScript. NET to Visual Basic. NET, and from J to C. Any of these languages will become just another "script" language supported by WSH. Windows Forms are, and will be, full-fledged applications distributed through compiled code. It is expected that WSH applications for. NET will be script-like applications distributed through source code that will be compiled on the fly.

Each of them will have its own use and gain its own space. Information about Script for the. Particularly helpful for understanding the big picture and getting started with some sample code are the articles in the Scripting Clinic column on MSDN Online. It provides structural improvements such as a new security model and the ability to run scripts remotely.

The programming power for administering Windows is significantly increased and writing script code is easier due to long-awaited, valuable features such as named arguments, the runtime information, and script controllers.

A brand new security model that is tightly integrated with security in Windows XP allows administrators to place fine-grained restrictions on scripts reducing the risk from malicious code.

In addition, local scripts can now run on remote machines, and enhancements to the object model reduce the amount of boilerplate code needed when writing professional code.

This overview of WSH 5. What's New in WSH 5. New File Format and Tags In addition to plain. StdIn WScript. ReadLine WScript. Count - 1 WScript. Safe Scripting Administration WSH was originally designed to be a tool for system administrators to programmatically access programs, the file system, e-mail, FTP sites, and so forth.

Script Authentication and Signing Verifying a script is the process that determines whether the script that you are about to run is coming from a trusted source.

SignFile File, Cert, Store Script verification can also be accomplished programmatically through the methods of the Scripting. Signer" Signer. SignFile ScriptFile, CertificateName, CertificateStore In addition to signing a script file, you can also sign code stored in an in-memory string by using the Sign method. VerifyFile "MyFile. CreateScript scriptName, serverName remScript. Execute The scriptName argument indicates the script's path and switches as they would be typed at the command prompt.

Controlling the Remote Script Once the WSH automation server is successfully started, it returns an instance of the WshRemote object, which allows the caller to execute the script remotely and access information about the remote script instance. CreateScript scriptName, srvName remScript. Sleep Wscript. Echo remScript. Quit Notice that the Status property of the WshRemote object is only updated when it is effectively queried, minimizing the traffic between calling and called scripts.

A simple, yet effective approach is the following: shell. Script Arguments The WshArguments object provides access to the entire collection of command-line parameters in the order they have been specified.

Consider this command: program. If you want to assign it a string that may contain blanks, you must wrap it in quotes, like this: thescript. The following code returns the number of named arguments for the current script: MsgBox WScript. This sandbox all blocks any changes to the application's root folder. This prevents remote sessions from connecting to Store-based installs of PowerShell.

User-level configurations and SSH remoting are supported. These commands are not supported in a Microsoft Store instance of PowerShell. For more information, see Understanding how packaged desktop apps run on Windows. Beginning in PowerShell 7. Changes to virtualized file and registry locations now persist outside of the application sandbox. However, changes to the application's root folder are still blocked. For best results when upgrading, you should use the same install method you used when you first installed PowerShell.

Each installation method installs PowerShell in a different location. If you are not sure how PowerShell was installed, you can compare the installed location with the package information in this article. When you set up PowerShell Remoting you get an error message and are disconnected from the device. PowerShell has to restart WinRM. Now you can connect to PowerShell 7 endpoint on device. So the zip based install does not work. These instructions assume that the Nano Server is a "headless" OS that has a version of PowerShell is already running on it.

For more information, see the Nano Server Image Builder documentation. In both cases, you need the Windows x64 ZIP release package. Run the commands within an "Administrator" instance of PowerShell. If you want WSMan-based remoting, follow the instructions to create a remoting endpoint using the "another instance technique". For more information, see:. The following table is a list of PowerShell releases and the versions of Windows they are supported on.

These versions are supported until either the version of PowerShell reaches end-of-support or the version of Windows reaches end-of-support. Support for a specific version of Windows is determined by the Microsoft Support Lifecycle policies.
