Windows Programming

Notes The book has a snatch of insight from Mike Fries, the president and CEO of John Malone’s
Liberty Global, the largest cable company outside the US, that 99 per cent of all television
is still viewed on the living room TV set and that half the revenue of the industry today
comes from IP services that did not exist a decade ago.
To take the pace of innovations to the next level, and to keep subscribers from cutting the
cord, Fries prescribes three things: “Connect our content to other devices, including PCs,
tablets, and smartphones; bring third-party online content and apps to the TV; and
revolutionise the user interface and experience.”
Educative read that can add whole new perspectives to your otherwise routine TV viewing.

8.4 Summary

 Sometimes installing new software in Windows can overwrite the file associations for
other software. Graphics programs are notorious for this bad behavior.
 Fortunately, when it happens, you can follow these steps to change the default file
association so that double-clicking a file will open the program you choose instead of the
last program you installed.

 In this section, we’ll write code so that your menu items actually do something other than
displaying message boxes.
 In other words, the Edit > Cut menu will really cut text, and the Edit > Paste menu will
really paste text.
 So open up the project you completed for the previous section. Comment out or delete any
message box code.
 Despite initial appearances, writing a text editor is not a trivial task. Creating text editors
takes programming experience and a firm basis in theory.

 The internet is littered with hundreds of unfinished or poorly working text editors.
8.5 Keywords

FTP: File Transfer Protocol
Tokens: The token contains such useful information as the type of text, a description of the text,
and the position of the text in the file.
