They can be viewed best in XML Notepad's treeview. OK, listing properties for each item in a collection no longer has any secrets for you. Let's select specific items DVDs from the collection. List the titles and genres of all documentaries:. 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.
Is WSH 5. Not yet, but a number of interesting things are in the works as you read this. Skip to main content. This browser is no longer supported. Save this stack on your desktop. The file should be plain text. Save the file on your desktop as "Preferences. The XML data looks like this:.
Edit the script of the button by selecting it, then clicking on the "Script" button in the main menu bar. For this example we are going to load an XML file that contains preferences for our application. There are two parts to loading the preferences file. The first part is reading the file into memory and creating an XML "tree".
The second part is to process the tree and extract the data from it. This function reads the XML file, and returns the tree. The tree is represented as a number, the actual tree structure and data is managed by LiveCode and so we don't need to worry about it. Note that this code doesn't do anything just yet, because we haven't yet implemented the function readPreferencesToXMLTree and the command processPreferencesTree.
Next, we implement a function to read the XML. This is done in two steps, first the file is read into a variable like any other text file would be, secondly, an XML "tree" is created from the file. This tree allows us to manipulate the XML data easily. We use a series of calls to the XML library to extract each piece of information from the tree. The data loaded is displayed in the "Information" field but is not applied in this lesson.
Use the search and replace functionality within LiveCode to remove any characters or text that you think should not be present. You can do this because XML files are text files.
You can then process the XML data as you require. Thanks for your reply. That is what I have been doing, but wasn't sure if it was the correct way to go about it.
