Conventions used

There are a number of text conventions used throughout this book.

CodeInText: Indicates code words in text, database table names, folder names, filenames, file extensions, pathnames, dummy URLs, user input, and Twitter handles. Here is an example: "When you work with a different view of the master, Delphi will create a new .FMX file in your project folder. This file will contain the positions of the components for that particular screen format."

A block of code is set as follows:

procedure TForm1.DoDidFinish(Image: TBitmap); begin ImgInsta.Bitmap.Assign(Image); end;

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

uses REST.Utils, System.NetEncoding,Web.HTTPApp,System.Net.HttpClient,IdHTTP, uFrmLogin;

Any command-line input or output is written as follows:

net start PacktBooks_Service

Bold: Indicates a new term, an important word, or words that you see onscreen. For example, words in menus or dialog boxes appear in the text like this. Here is an example: "Open the Delphi IDE and create a Multi-Device Application. Note that there is the concept of viewing for different screen types."
