Conventions

 In this book, you will find a number of text styles that distinguish between different kinds of information. Here are some examples of these styles and an explanation of their meaning.

Code words in text, database table names, folder names, filenames, file extensions, pathnames, dummy URLs, user input, and Twitter handles are shown as follows: "We can achieve this using the <ipSecurity> element."

A block of code is set as follows:

<configuration>
  <system.webServer>
    <security>
      <ipSecurity allowUnlisted="true" denyAction="NotFound">
        <add allowed="true" ipAddress="xxx.xxx.xxx.xxx"      
          subnetMask="255.xxx.xxx.xxx"/>
      </ipSecurity>
    </security>
  </system.webServer>
</configuration>

When we wish to draw your attention to a particular part of a code block, the relevant lines or items are set in bold:

<configuration>
  <system.webServer>
    <security>
      <ipSecurity allowUnlisted="true" denyAction="NotFound">
        <add allowed="true" ipAddress="xxx.xxx.xxx.xxx"
          subnetMask="255.xxx.xxx.xxx"/>
      </ipSecurity>
    </security>
  </system.webServer>
</configuration>

New terms and important words are shown in bold. Words that you see on the screen, for example, in menus or dialog boxes, appear in the text like this: "To create a resource group, click on Resource groups in the left-hand sidebar menu."

Warnings or important notes appear in a box like this.

Tips and tricks appear like this.
