Study Notes

Visual Studio.NET IDE

The Visual Studio.NET IDE is where the various windows show their purposes, and can be customized by moving or docking them.
The Server Explorer provides management access to servers on the network, allowing the creation of database connections and viewing of services.
The Toolbox contains reusable components that can be inserted into an application, such as buttons, data connectors, and customized controls.

Design Window

The Design window is where most of the action takes place, and is where controls can be added to a form.
The Windows Forms tab contains a list of standard .NET controls for Windows forms, which can be scrolled through using the up and down arrow buttons.
Controls can be added to a form in any order, and do not affect the functionality of the application.

Adding Controls to a Form

To add a control to a form, click on the control in the Toolbox and then drag it to the desired location on the form.
Alternatively, controls can be added by double-clicking on the required control in the Toolbox.
The cursor will appear as a crosshair with a floating letter A when placing controls.

The Visual Studio.NET menu is dynamic, meaning that items will be added or removed depending on the current task.
The menu items include File, Edit, View, Tools, Window, and Help, which pertain to various activities such as opening and closing files, editing, and building projects.

Project Setup

During the installation process, the Service Releases option can be selected to check for updates, which can include additional documentation, bug fixes, and more.
The installation log can be safely ignored unless errors were reported during installation.

Visual Basic.NET IDE

The Visual Basic.NET IDE is not required to write applications in the Visual Basic.NET language, but it is the easiest way to do so.
The IDE provides a visual interface for writing code, which responds to events and allows the programmer to write code only for those events that are relevant to the program.

Learn how to write code that responds to specific events in Visual Basic.NET. Just like navigating through a hallway, your program can react to user actions to complete tasks efficiently without unnecessary steps. Explore the simplified process of event handling in Visual Basic.NET.
