  1. Chapter 2 Part C – More on the Help System and The Object Browser (scan quickly for future reference)

  2. Objectives • Learn more about the parts of the Help system and how to access them • Use the Visual Studio Object Browser • Learn about Types of Visual Studio Applications (This is a continuation of Lecture Set 2B)

  3. Class Help Pages (Inheritance Hierarchy Section) • All types inherit from the superclass named System.Object • The inheritance hierarchy section shows the inheritance hierarchy for a particular type • For example, System.Console inherits directly from System.Object

  4. Console Class Help Page – Inheritance Section

  5. Class Help Pages (Other Sections) • The Thread Safety section describes how a type works with multiple processes • The Platforms section describes which versions of Windows support the class or other type • The Version Information section describes which versions of Visual Studio and the .NET Framework support the class or other type

  6. Navigating Through the Help System • The Help system can be navigated in the following ways: • Using a table of contents • Using an index • Searching by keyword • Task-based Help using the How Do I tab • Dynamic Help • Favorites

  7. Introduction to Help Filters • The Help system is quite complex and voluminous • In all, the Help system is over 3 gigabytes in size • Helpfilters restrict the Help displayed to a functional group of topics • The available Help filters differ based on the Visual Studio or Visual Basic edition installed

  8. Common Help Filters • The .NET Framework filter displays topics related to the .NET Framework class library • The Visual Basic filter restricts topics to both Visual Basic and the .NET Framework • Other filters apply to other .NET languages • The Web Development (.NET) filter includes documentation for Web development • The Windows Forms development filter includes documentation for desktop applications • The Visual Basic filter includes these topics too

  9. Using the Table of Contents • The Help table of contents works similar the table of contents in a book • Drill-down folders can be expanded or collapsed • Help topics are organized along functional boundaries • Use the Table of Contents for tutorial-based learning

  10. Selected Contents Topics • The Development Tools and Languages folder describes how to use Visual Studio and Visual Basic • The .NET Development folder and .NET Framework SDK folders contain the reference to the .NET Framework itself

  11. Contents Window

  12. Using the Help Index • The Help index works like an alphabetical book index • Select a filter as desired • Type the name of the desired Help topic • Matching entries appear in the list box in the lower part of the window • Double-click a topic to select it • The search for topics is made in a case-insensitive way • Many topics appear organized by namespace, class, and member name

  13. Help Index Window

  14. The Help Search Window • Selected words in the Help pages are marked as keywords • The same keyword can appear in several Help pages • Custom filters can be applied to the search • The Help Search window contains two sections • The top section contains search parameters • The bottom section displays matching topics • Click a topic to display the matching Help page

  15. Help Search Window

  16. Using “How Do I” Help • How Do I Help is task-based rather than feature-based • Help topics are organized hierarchically • Each topic contains a hands-on tutorial • Most examples are introductory

  17. “How Do I” Help Window

  18. Introduction to the Object Browser • The Object Browser is used to examine the types that make up the .NET Framework class library and the types in developer-created applications • The Object Browser has a drill-down interface • Namespaces and types appear in the left pane • Members appear in the top right pane • Syntax appears in the lower right pane

  19. Object Browser – My Solution Component Selected

  20. Types of Visual Studio Applications • Templates are used to create different types of applications • The supported templates vary based on the installed Visual Studio edition • Common templates • Console Application project • Windows Application project (what we will use) • Class Library project • ASP.NET Web Application project (see CIS 4342, 4344) • Web Service project (CIS 3309 (intro), 4342)

  21. Applications Templates
