Goal IDE definition Components Terminology Properties, method and Events Software release stages

Definition: IDE: It is an integrated development environment for developing, compiling, debugging and running applications. All development tools needed are provided in a single window interface

IDE Sub-Windows Solution Explorer Properties windows Tool box Debug / immediate window Task List Error List Object browser Output window

Terminology A VB.NET program consist of a project / Solution (sln). Each project may have: – Form – Class – Module – Resource – App Data Solution is the group of project

Terminology The exe file is present in bin\debug There are three phases / modes of a program i.e., Design, debug / pause and runtime. There are three modes of development known as software release stages: – Pre-alpha – Alpha – Beta

Execution Control Starting (or Continuing) Execution Breaking Execution Stopping Execution Stepping Through Your Application – (Step into, Step over and step out) Running to a Specified Location Setting the Execution Point

Properties, method and Events

Properties can be thought of as an object's attributes, methods as its actions, and events as its responses. Properties: Balloon.Color = Red Balloon.Diameter = 10 Balloon.Inflated = True Methods: Balloon.Inflate Balloon.Deflate Balloon.Rise(5) Events: Sub Balloon_Puncture() Balloon.MakeNoise("Bang") Balloon.Deflate Balloon.Inflated = False End Sub

Properties Important properties are Location (Left, Top) Size (height, width) Text Name (lbl, cmd or btn, txt)

Methods Important methods are: Move Update Refresh Hide Show

Events Click Load MouseMove Keydown

Software Release Stages Pre-alpha: At this stage designers are still determining exactly what functionalities the product should and should not have. Alpha: It often lacks features promised in the final release but demonstrates the feasibility and basic structure of the software. The alpha build of the software is usually the first build delivered to the software testers.

Software Release Stages Beta (beta version or beta release): Implements all features in the initial requirements analysis. Some developers refer to this stage as a preview, as a technical preview (TP) or as an early access. Other versions are: Release candidate Gold/general availability release Box Copy Stable/unstable (Open Source)
