EXPERIMENT : 1
Aim: Visual basic an introduction of console and GUI programming technique Explain
new project window , property explorer , output window dynamic help, window
management .
The Visual Basic Express Edition integrated development environment (IDE) makes it easy for
you to create programs for Microsoft Windows. The IDE contains several tools that help you
design your applications and write, edit, and debug your application code. The following links
will help you to familiarize yourself with the Visual Basic Express Edition IDE.
 Start Page
The Start Page may be used to select from the recent projects. A New Project may also be
started from the start page by clicking on the New Project Link. This page is useful to
search for help in all the Visual Studio Languages. The start page is displayed in the
browser & its URL is vs:/default.htm

 Solution Explorer
Solution Exploreris the solution
directory and helps in managing
the open project files. The files
are displayed in a hierarchical
view. By default, Solution
Explorer is located on the right
side of the IDE. If Solution
Explorer is not visible, it can be
made visible by clicking View
Menu & then clicking the
Solution Explorer.
 ToolBox
The Toolbox is a container for all the controls
that can be added to a Windows Forms
application or a Windows Presentation
Foundation (WPF) application. By default,
theToolbox is located on the left side of the
integrated development environment (IDE). If
theToolboxis not visible, it can be made visible
by clicking View and then clicking ToolBox.
The controls in the ToolBox are divided to
various groups according to their functionality &
usability. The controls are not visible in the
ToolBox when you are not in the Code Editor.
The Control can be added to the Window Form
by dragging it to the Application Window.

The various categories in which the controls are grouped are:
Tab name Description
All Windows
Forms
Contains all the standard Windows Forms controls that are
available in theToolbox.
Common Controls Contains the most common controls that are typically used
in Windows-based applications.
Containers Contains controls that hold other controls, such as
GroupBox controls and Panel controls. Containers can help
isolate a set of controls from other controls on the form.
Menus and
ToolBars
Contains controls that enable you to create menus and
toolbars for your application, such as the MenuStrip and
ToolStrip controls.
Data Contains controls that help you easily work with data in
your application, such as the DataGridView control.
Components Contains components that typically do not have a user
interface, such as the Timer and the ErrorProvider.
Printing Contains controls that enable you to provide printing
capabilities to an application.
Dialogs Contains controls that let you use common dialog boxes in
your application, such as the SaveFileDialog,
FolderBrowserDialog and FontDialog controls.
 Properties Window
Properties of a form and any controls on the form in
the integrated development environment (IDE) can be
set by using the Properties window or by writing code
in the Code Editor. For example, to display text on a
button, you can set the button's Text property.
