Creating Simple Visual Basic .NET Windows Applications CHAPTER TWO Matakuliah : T0063 – Pemrograman Visual Tahun : 2009
Chapter Introduction The Integrated Development Environment (IDE) is used for modern software development. The IDE contains tools to write code, build a GUI , and test and debug applications. Overview of the application construction process. Design issues are addressed. Visual Basic .NET controls are examined. The MsgBox statement and InputBox() function are visited. A project is developed as a working application.
Objectives • Design and construct simple complete applications from scratch. • Explain the structure of Visual Basic .NET. • List the characteristics of several Visual Basic .NET controls. • Identify the purpose of each major control of the Visual Basic .NET IDE. • Explain basic programming practices that contribute to the readability of programs.
2.1 From New Solution to Finished Application • Overview of the Construction Process • Design Mode • Run Mode • Break Mode
Design Time and Run Time • In design mode, the project is in design time. • In run mode, the project is in run time. • Some errors can be found and corrected in design time. • Other errors can only be detected during run time.
2.2 Overview of Controls • Standard controls are used to create user-friendly applications. • Standard controls help users lower the learning curve for new programs.
Categories of Controls • Trigger: Initiate processing • Ex. Button, MainMenu, and Timer • Input: Get data from user • Ex. TextBox, RadioButton, and CheckBox • Output: Display results to user • Ex. Label, DataGrid, and ListView
Categories of Controls (cont.) • Organize: Group other controls • Ex. Form, GroupBox, and Panel • Data Access: Interface with databases • Ex. Entire Data Group and DataGrid
The Correct Control for the Job • Chose controls to satisfy user requirements. • Different controls are good for different tasks. • The Button, Label, and Textbox controls are introduced.
2.3 The Visual Basic .NET Development Environment • The IDE helps develops create efficient and effective solutions. • The IDE for Visual Basic .NET is common to all the other tools available in the Visual Studio. NET suite.
