Visual programming
• Visual programming is a way of creating software applications
without writing code. It's a graphical representation of how different
components interact, allowing developers to create complex
programs quickly and easily.

4 Basic Parts of visual Basic
• Procedures, operators, properties, and events are the only
programming elements that can hold executable code

Basic Syntax
• Object: Objects have behaviors and states. An object is a class
instance.
• Class: A class is a template that outlines the behaviors/states that
objects of its type can support.
• Method: A method is essentially a behavior. Many methods can be
found in a class. Methods are where logic is expressed, data is
manipulated, and all actions are carried out.
• Instance Variables: Each object has a collection of instance variables
that are unique to it. The values assigned to these instance variables
define an object's state.

Introduction – Visual Studio 2012
 Visual Studio 2012 is Microsoft’s Integrated Development
Environment (IDE) for creating, running and debugging
apps (also called applications) written in various .NET
programming languages.
6

Create a New Project
 Start Page  New Project
Or
 File  New  Project
A Project: is a group of related files, such as the Visual C# code and any images that
might make up an app.
8

 Make sure to choose the proper language “Visual C#”.
 And from the templates displayed, choose “Windows
Forms Applications”
 This template will enable you to start your project with
the first screen that will be displayed to the users of the
resulted application. This form (window) will be filled
with controls that can be used by the user.
 Give a name of your project, specify its location on
your PC, and finally give a name to the solution. For
beginners, we use the same name of the project.
10

 A Solution: contains several projects, and it is usually
used for large systems.
 In this course, we will create only one project in a
solution.
 Now, Press “OK”
11

A Project “Start” is created
12

Forms.cs
 Form1.cs [Design]
This window displays the
file form1.cs in design
mode.
In this window you can
add the needed controls
to the form.
Your project may contain
several forms that act as
the windows of the
application.
13

Solution Explorer
 Solution Explorer
is used to review
all files in your
project. Mainly,
the form1.cs file,
references, and
any images you
include in the
project.
14

Toolbox
 Toolbox: is a window
that contains all the
controls and
components that you
can add and use in a
form.
 The controls are
categorized in several
categories.
15

Toolbox
 Common Controls: is the most
used categories, since it contains
the most common controls that
you can find in most forms. For
example, buttons and textboxes.
 To add any control from the
toolbox to the form, drag and drop
the control to the desired location,
or double click on it, and it will be
placed in a location automatically
selected by the system.
16

Toolbox
 This image displays
a form after adding
a button to it.
17

Properties Window
 The Properties window,
displays all properties
associated to the selected
control.
 You can see at the top of
this window, in the image,
that these are the
properties of Form1.
18

Properties Window
 Here, Form1 is
selected
(check the
selection
handlers), so
the properties
displayed are
associated to
the form.
19

Properties Window
 Here, button1 is
selected, so
button1 properties
are displayed in
the window.
20

Properties Window
 Here, textBox1 is
selected, so
textBox1
properties are
displayed in the
window.
 Note that there
are some
properties are
common with the
button
properties, and
others are special
for the textbox.
21

Properties Window
 You can display
the properties of
any control, either
alphabetically, as
in the first image,
or categorized as
in the second
image.
22

Properties Window
 Note that each property has
a name and a value of a
certain data type. For
example, property named
“Text”, has a string value of
“button1”, a property named
“TabIndex”, has an integer
value of “0” and a property
named “Visible” has a
boolean value of “True”.
23

Properties Window
 The same property
window can be used to
display the events
associated to a control.
 The concept of Events
will be discussed in
Chapter 2.
24

Project Physical Folder
 When the project is created, a physical folder is created
with the same project name in the selected location, and
all files listed in the Solution Explorer, can be found there.
25

Run the Project
 Click on “Start”
button, at the
toolbar in Visual
Studio Window,
and an execution
file will be
generated of the
project, and it
will be executed
as displayed in
the image.
26

Run the Project
 Go to the Project
folder, from bin
 Debug, you can
find the execution
file
projectname.exe
(start.exe), when
you double click
the file the project
will be
distributed, even
if the Visual
Studio IDE is
closed.
