Download wsh and vbscript files from website
Silent script. We have an alternative: Hide prompt and show progress on the same Window. There is a problem: We lose the real-time view of our download. We have to wait download finish to show output. We will use it to call Command Line in the next lines.
It will read all lines of file until the end of file, and then exit from file. Explaining: We use InStr function to check if a string have some text. If the actual line have "Content-Length", it will get the value. We use Mid to read the string from the character 19 to the final of the string, removing "Content-Length" and maintaining only the size. We can use it to compare the size of the actual file with the server, for example. Use -N to let WGet make this automatically.
You can read another information from header data using this method, just use the right values on Mid. It means that you do not need to redistribute anything with your code if you just want to download a small file. I don't think that there is much things to explain here. Version 6. You can redistribute the executable and install it Recommended.
If you do not do that, it will use Version 3. Remember to warn Windows Server users that they need to change Internet Security Zone to allow scripts have internet access! It decrease security if a malicious script be executed! With this alternatives, you can download a file using VBScript.
I recommend you using WGet for large files, then the user won't think that the program stopped. Open BinaryStream. Etay Gudai Etay Gudai 5 5 silver badges 18 18 bronze badges. Manuel Manuel 31 2 2 bronze badges. Network" objNetwork. FRanck FRanck 1 1 1 bronze badge. Try: CreateObject "WScript.

Reducing the weight of our footer. As you now know, VBScript is a scripting language that allows you to develop scripts that automate tasks that would otherwise have to be manually performed in the environment in which they execute.
VBScripts are stored as plain text files with a. This makes them easy and quick to develop. Unlike the stand-alone implementations of many scripting languages, such as Perl or Python, VBScripts cannot execute without an execution host.
However, over the years Microsoft has extended its capabilities to allow it to function in numerous different settings. VBScript is now supported in a number of different environments, including. As you can see, once you have mastered VBScript within the context of WSH script development you'll have a number of other avenues in which you can begin using your new VBScript programming skills.
VBScripts cannot execute without an execution host. Therefore the language's capabilities vary greatly based on where they are run. For example, when embedded within HTML pages, VBScript has the ability to access and manipulate forms, frames, links, images, and other Web-page-based objects.
However, as the purpose of this book is to teach you how to program using VBScript within the context of the WSH, I think it's best that we focus on the capabilities that VBScript has when executed in this environment. While game development is certainly a great way to have fun while learning a new language, it is important to understand the reason why Microsoft enabled VBScript to operate in the WSH, and to be familiar with the capabilities that Microsoft has given to VBScript within the context of WSH script development.
VBScript provides programmers with a quick development tool for creating small applications and utilities, and for prototyping new applications. System and network administrators use these tools to automate system administrative tasks, such as. Some tasks simply take a long time to perform manually or must be done so often that they become a bother. By providing the ability to automate these tasks, VBScript provides a powerful yet easy way to use programming tools. Once developed, script execution can be automated using the Windows scheduling service.
This allows you to run your scripts at the times that are most convenient for you. For example, suppose you wrote a script that reorganizes the locations of files on your computer by going out and moving them from various folders into a centralized location. This way, at the end of each month, you can run the script and reorganize a month's worth of messy file placement.
The number of files to be moved may be such that it takes the script a while to complete its work, during which time the computer runs slowly and is no fun to use. Fortunately for you, however, VBScripts can be scheduled—you can set up the execution of this script to run at night, over the weekend, or at any time that you don't plan on using your computer.
At the time, another client-side Web scripting language called LiveScript was already making big waves in the Internet community. LiveScript was created by Netscape, who later changed its name to JavaScript. Despite the similarity in name, JavaScript had very little in common with Java, which was also fast becoming popular in the mid-to-late s.
As I have already mentioned, JavaScript's popularity as a client-side Web scripting language has continued over the years, while VBScript's stalled.
Even today, the only way to perform client-side Web scripting and to be sure that everyone with an Internet browser has access is to use JavaScript. Still, Microsoft has remained committed to the development of VBScript over the years.
It released VBScript 2. This version was packaged with multiple Microsoft products, including. VBScript 3. Visual Basic programmers, computer administrators, and technology enthusiasts with a background in Visual Basic found VBScript easy to learn.
It quickly proved itself to be a great language for developing small scripts to perform tasks that did not merit the development of a complete standalone application.
Microsoft later released VBScript 4. Microsoft gave VBScript 4. In , Microsoft released VBScript 5. Along with these goodies came WSH 5. As you can see, Microsoft decided to sync up their version numbers with this release.
Since WSH 5. VBScript is the third member in a family of three closely related programming languages. These languages include. Visual Basic is the original member of this family, Microsoft having first introduced it in In the last 12 years, Microsoft has steadily improved Visual Basic, releasing a number of versions along the way.
The most current version of Visual Basic is Visual Basic. NET framework. NET is a Microsoft framework that has been designed by Microsoft from the ground up to support integrated desktop, local area network, and Internet-based applications. NET framework assists in application development by facilitating the exchange of data over a network—including the Internet. Visual Basic is generally used to create stand-alone programs. What this means is that once written and compiled into executable code, a Visual Basic application does not need anything other than a Windows operating system to execute.
Visual Basic earned a reputation very early on for being easy to learn. As a result, it did not take Visual Basic long to be come one of the most popular programming languages ever developed.
Today it is taught in colleges around the world and is used to build applications in companies of all sizes and types. While Visual Basic's IDE provides a rich and powerful programming development environment, it takes a substantial amount of time and effort to learn. To learn more about Microsoft Visual Basic. Similarly, VBA for Microsoft Access provides a powerful programming language for creating applications that require a Microsoft Access database.
An IDE is an application development program that gives programmers the tools required to create applications using a particular programming language. An IDE provides tools such as a compiler, which translates application code into a finished executable program; a debugger, which assists in tracking down and fixing programs; and tools for managing projects, which may consist of multiple applications.
Unlike Visual Basic applications, which can be compiled into fully executable programs, VBA can only be compiled into a format known as p-code, which you can think of as partial compilation.
Using p-code, VBA code can load and run faster than VBScript, which is an interpreted language but will still run slower than a Visual Basic application. Thus, VBScript is the slowest of the three languages. However, since VBScripts do not have to be compiled prior to execution, you can save a lot of time during development because you will not have to stop and compile your scripts every time you make a change and want to see how it affects the application.
However, this does not mean that you cannot find some perfectly good third-party script editors that will provide you with an advanced script development environment. It provides all of the following features:. Included among the information you'll find here is.
The VBScript documentation is divided into two parts. It also provides a basic overview of VBScript scripting. Here you will find every VBScript statement fully documented, as well as an outline of its syntax and short coding examples. In addition to the on-line version of these help files, Microsoft allows you to download and install a local copy for easy access.
To do so, follow these steps:. Click OK to perform the install. Once it's installed, you can view the documentation from the Windows Start Menu. The Windows Script Technologies help dialog will then appear, as shown in Figure 1. Let's turn the focus of this chapter back to the development of your first VBScript, the Knock Knock game.
This project will demonstrate the steps involved in creating and running your first VBScript game. Along the way, you'll learn how to use VBScript to create a script that can communicate with the user via popup dialogs. You will also learn a little about conditional programming logic. The Knock Knock game's design is very straightforward, involving very basic programming techniques.
The game begins by displaying the message "Knock Knock" in a popup dialog. It then waits for the player to reply by typing "Who's there? If the player fails to exactly type the proper responses at any point of the game, an error message will be displayed inviting the player to try again. The first step in creating the Knock Knock game is to start up your script editor and use it to create an empty VBScript file. For example, to create the script using the Notepad text editor on a computer running Windows XP, you would execute the following steps:.
Now let's begin the script by writing its first VBScript statement. The first thing that the game is supposed to do is display a popup dialog displaying the "Knock Knock" message and then wait for the user response.
This task is performed surprisingly easily using VBScript, and can be done with a single line of code. A statement is a line of code. Statements generally consist of a single line of code but may be spread over two or more lines depending on their size. In plain English, what this VBScript statement does is display a popup dialog with a "Knock Knock" message and then waits for the player to type something into the dialog's text field and click the OK button. Let's break this statement down into pieces and see how it works.
This function displays a popup dialog box with a text entry field that allows the script to collect text input from the player. In order to communicate with the player, the InputBox function allows you to display a message.
In the case of this example, the message is simply "Knock Knock," but could just as easily be "Hello, what is your name? Finally, the text typed by the player in the popup dialog's text field is temporarily assigned to a variable called Reply1. Variables provide scripts with the ability to store and later reference data used by the script. Functions and variables are fundamental components of VBScript.
Unfortunately, it is difficult to write even the simplest scripts without using them. For now, don't worry too much about them and keep your focus on the overall steps used to create and run the Knock Knock game. I'll go over the use of variables in great detail in Chapter 4, "Constants, Variables, and Arrays," and the use of functions in Chapter 7, "Using Procedures to Organize Scripts.
The player's role in this game is to first type in the phrase "Who's there? Once the player has typed in this message and clicked on the OK button the script will need to perform a test that validates whether the player is playing the game properly. The following three lines of code accomplish this task:.
The first two lines of code go together. The three dots that you see in between these lines of code are placeholders for more statements that will be inserted in the next section.
The first of these two lines tests the value of Reply1. Remember that Reply1 is a variable that contains the response typed in by the player. This statement checks to see if the values stored in Reply1 match the phrase "Who's there?
Otherwise, these statements will not be processed. If this is the case, then the rest of the third statement executes displaying an error message. There are a number of reasons why the text performed by the third statement may prove true. These reasons include. If you are creating the script as you read along, then your script should now contain the following statements:.
It is now time to add three lines of code that will reside within the second and third lines of code just shown. The first of these three lines of code is as follows.
