I can see everyone's frustration with this book. Had I not read Don Jones' book . I probably would've went through the first two chapters and threw the book away and gave up on Powershell. It does a very poor job at explaining what's going on, it almost seems erratic and all over the place. His commands use abbreviations and positional parameters followed by an explanation with a definition such as. So being said this book isn't a .

VMware is the global leader in virtualization software, providing desktop and server virtualization products for virtual infrastructure solutions. Download Windows PowerShell 4.0 book, commands, guide and best practices for.NET developers for Windows 8 and Windows 7 from Microsoft.

Even with the intermediate logo on the cover the book claims you don't require any knowledge of programming, Powershell, or scripting, I would agree with other reviewers that this claim is false. The book needs better organization, more thought out beginner examples, and a deeper explanation on how Powershell works. That being said, if you know Powershell or have already read Don Jones book, there is still a lot of good info in here that is missing from Jones book. So think of this book more as steak with bones, eat the meat and leave the bones, but only after you know how to eat the steak.

Use the . NET Web. Client Class in Power. Shell Scripts to Access Web Data. Executive Summary: Windows Power. Shell doesn't have any cmdlets specifically designed to download Internet data.

However, you can use the Microsoft . NET Framework's System. Net. Web. Client class in Power. Shell scripts to download Internet data. To demonstrate how to use the Microsoft . NET Framework's Web. Client class, here are three Windows Power.

Shell scripts—Get- Web. String. ps. 1, Get- Rfc. Copy- Web. File. ps. Uniform Resource Identifier (URI) you specify. Although Windows Power. Shell doesn't have any cmdlets specifically designed to download Internet data, the Microsoft .

NET Framework exposes Internet data access. You can write Power. Shell scripts that use this Web.

Client class to retrieve text and binary data from Internet addresses. To show you how, I've created three scripts: Get- Web. String. ps. 1, Get- Rfc. Copy- Web. File. ps.

After I explain how to use these scripts, I’ll discuss how they work so you know how to create your own custom tools. Downloading Text- Based Content. Get- Web. String. Listing 1 is a script that lets you download text- based content from the Internet. To obtain Get- Web.

String. ps. 1 and the other scripts I discuss in this article, click the Download the Code Here button at the top of the page. You need to place these scripts somewhere in the search path Power. Shell uses for finding files. If you don't have a folder set up for this, you might want to add one as outlined in the sidebar . For example, suppose you're checking the Federal Reserve's daily exchange rates. These rates are always posted at http: //www. Get- Web. String http: //www.

There are many text- based resources on the Internet that can be easily retrieved this way. For example, the Internet Engineering Task Force (IETF) makes all its Request for Comments (RFC) documents available as text at an address that follows the format http: //www. NNNN. txt, where NNNN is a 4- digit RFC number. For example, to retrieve RFC 1. Get- Web. String http: //www. Because IETF follows this format, you can create a script solely for the purpose of retrieving RFCs, as Get- Rfc.

Listing 2 shows. Get- Rfc. RFC number as an argument and returns the corresponding RFC text, so all you need to do to get RFC 1.

Get- Rfc 1. 40. 8Because Power. Shell automatically prepends Get- to searched cmdlet names, you can abbreviate the command torfc 1.

Power. Shell only prepends Get- while searching for a command. So, if you specify an explicit path—for example, if you saved this script as C: \tmp\Get- RFC. Power. Shell location to C: \tmp, you could invoke the script and have it retrieve RFC 1. Get- RFC 1. 40. 8.\Get- RFC 1. However, you can't use these commands.

C: \tmp\RFC 1. 40. Power. Shell isn't performing a command search.

Instead, you've told it that you want to load a command file explicitly in the C: \tmp folder, with the exact basename of rfc. Power. Shell expands command names only when it's performing a search for a command. Whichever technique you use, the data is returned as in- console text, so you can treat it like any other Power. Shell data. You can pipe it through the More command to page through the RFC text: Get- Rfc 1. If you want to see the content in the Power.

Shell console, you can use$rfc. Get- Content rfc. Get- Web. String. Internet as from a locally stored file. It works with all protocols that can be used for direct text data transfer (including FTP) and can even be used to read local files by specifying a file- system path.

One problem you can encounter with Get- Web. String. ps. 1 is that the underlying Web. Client class doesn't automatically decide what encoding is used for text it reads from a particular location. For example, suppose you want to use Get- Web. String. ps. 1 to read the Unicode text file at C: \tmp\weather.

If you use the default command. Get- Web. String C: \tmp\weather.

Figure 1. Unicode files allocate 2 bytes for each character; for most Western European languages, the first byte is 0. Because Get- Web. String. ps. 1 assumes each byte is a separate character, the first byte of each character is assumed to be the character with a code value of 0—the null character. This is typically displayed in console windows as an empty space, causing the stretched out look you see in Figure 1. You can modify the encoding that Get- Web.

String. ps. 1 uses to read files with the - Encoding parameter. To read the Unicode file C: \tmp\weather. Unicode after the - Encoding parameter: Get- Web. String C: \tmp\weather.

Encoding Unicode. The - Encoding parameter name is optional. Get- Web. String.

Get- Web. String C: \tmp\weather. Unicode. With the proper encoding specified, you'll see the text rendered as shown in Figure 2. The values you can use with the - Encoding parameter are ASCII, Big. Endian. Unicode, Default, Unicode, UTF3. UTF7, and UTF8. All the values except for Default are the standard character encodings. Default represents the system's current code page.

I won't go into details of character encodings here, except for when dealing with Unicode text. Remember that spaced- out text generally indicates that the file is Unicode. If you get a series of blocks onscreen when you try Unicode, the file might be Big. Endian. Unicode, where each pair of bytes is reversed compared to standard Unicode. Figure 3 shows the onscreen display you get with a Big. Endian. Unicode file when you try reading it without the - Encoding parameter, as a Unicode file, and as Big.

Endian. Unicode file. Fortunately, the next application of the Web. Client class—copying files from the Internet—isn't affected by the encoding of characters. Downloading and Copying Text- Based Content. Listing 3 contains Copy- Web.

File. ps. 1, which lets you download and save text- based content from the Internet in a single step. For example, if you run the command.

Copy- Web. File http: //www. RFC 1. 40. 8 from the Internet and save it to a file named rfc. Power. Shell location. When you use Copy- Web. File. ps. 1, you need to be aware of three limitations: Unlike files downloaded through Microsoft Internet Explorer (IE), there's no execution blocking. If you use Copy- Web.

File. ps. 1 to save an executable locally and run the executable later, you won't receive a warning that it came from an Internet location. If you choose to save the target file under a different name or in a different location, you should specify the entire pathname; otherwise, it might end up where you don't expect it (more on this later). You can use environment variables in the path to save some typing. For example, to save the rfc.

Temporary Files folder, you can use the following command: Copy- Web. File http: //www. If you're wondering how the code $env: temp works, see the sidebar . If you repeatedly run the previous command, Copy- Web. File. ps. 1 will silently overwrite the rfc. Understanding the Scripts.

Get- Web. String. Get- Rfc. ps. 1 and Copy- Web. File. ps. 1 are wrapper scripts for the Web. Client class. Understanding how these scripts work can help you create your own custom scripts. Get- Web. String. Let's start with Get- Web. String. ps. 1 in Listing 1.

In callout A, I declare the named parameters $Uri and $Encoding. I could have used Power. Shell's generic $args variable, but this way, I have meaningful names for the parameters.

I can also specify a default value for the - Encoding parameter. In this case, that value is the string Default, which represents the system default encoding. In callout B, I use Power. Shell's New- Object cmdlet to create a System. Net. Web. Client object and assign it to the $Web.

Client variable. Note that you can omit System. For clarity and to slightly speed up the object creation process, I generally include the System. Password Fighter Pro 1 1 16 Multilingual Seriale more.

This code might seem to work like magic if you don't know much about the Web. Client class, so it's worth stepping through in detail. To find out the Web. Client class's properties, you can run the command. New- Object System. Net. Web. Client . The Encoding property is defined as System.
