Getting started
Creating a new visual studio C# project:
Once Visual Studio is running the first step is to create a
new project. Do this by selecting New
Project from the File menu. This will cause the New Project window to appear containing a range of
different types of project. For the purposes of this tutorial we will be
developing a Windows Forms
Application so make sure that
this option is selected.
CREATING NEW PROJECT
The first thing you do when you want to create a new application is to create a NEW PROJECT.
This can be done from start page.
New project created from the NEW PROJECT window:
Then the “NEW PROJECT” window will
appear.
In this window
you will select an appropriate template based on what kind of application you
want to create, and a name and location for your project and solution.
The most common
applications are:
- Windows form application.
- Console application.
- WPF application
- ASP.NET web application.
- Silverlight application.
Select WINDOWS FORMS
APPLICATION.
TOOL BOX
When you select
WINDOWS FORM APPLICATION, you will get FORM DESIGN WINDOW,it is used to design
USER interface by making use of TOOLBOX on the left side of window,
The TOOLBOX
contains all the necessary controls, etc. You need to create a user interface
by making use of these controls as shown in figure below.
In order to use these controls, just drag
and drop it on to your Design forms, as shown in figure.
Figure shows TOOLBOX and DESIGN FORM:
The following screenshot shows, making use
of these toolbox controls for designing the user interface on DESIGN FORM.
PROPERTIES WINDOW
Each TOOLBOX we have used on our form has
many properties that we can set. This is done by using Properties window. We
can find the property window on the right bottom side of your project.
BUILD AND DEBUGGING TOOL
The
visual studio has lots of Build and Debugging Tools,
BUILD MENU:
Below we see the Build menu. The most used Build tool is BUILD SOLUTIONS.
DEBUG MENU:
In
order to RUN or DEBUG your windows form we make use of DEBUG TOOLs. The most
used debug tool is START DEBUGGING.it can be find the shortcut for this on the
top of your visual studio windows.
Windows
programming
When
creating ordinary windows form application, we can select between the
following:
·
Windows form Application
·
WPF application
HELLO WORLD
We start by creating traditional “HELLO
WORLD” application using Windows Form Application is shown below. Thevisual
studio UI shown below.
In this application we make use of simple
textbox and Button(Button name is changed to Submit in the properties) when we
click on submit the “HELLO WORLD ”massage will be displayed in the Textbox.
The
OUTPUT of this form as shown below:
THE CODE IS AS FOLLOW:
using System;
using System.Collections.Generic;
using System.ComponentModel;
using System.Data;
using System.Drawing;
using System.Linq;
using System.Text;
using System.Threading.Tasks;
using System.Windows.Forms;
namespace WindowsFormsApplication9
{
publicpartialclassForm1 : Form
{
public Form1()
{
InitializeComponent();
}
privatevoid textBox1_TextChanged(object sender, EventArgs e)
{
}
privatevoid button1_Click(object sender, EventArgs e)
{
textBox1.Text = "HELLO
WORLD";//displaying hello worldin the
textbox.
}
}
}
