C# is one of many languages supported by .NET

5. Types of Projects
Graphical / Forms
Text / Console

6. Project Name
You can specify the project name as you create a new project or as you save a project
This is where the solution folder will be created
Project name
Project name
Solution name

7. Console Applications
Hello World

8. DESIGN MODE
Forms Applications
RUN MODE

9. Visual Studio Modes Visual Studio has 2 different modes
Design
Runtime
Control properties can be modified
at design time (static), or
while the program is running (dynamic)

10. Visual Studio Environment
Visual Studio is a professional integrated development environment (IDE)
Tools:
Designer Window (1)
Solution Explorer Window (2)
Properties Window (3)

11. Forms Basics
TOOLBOX
Form is a container for the controls that the user will use while the program is executing. Add controls from the toolbox

12. Objects Objects are created from their associated Class
A Class is like a blueprint which defines the properties and methods/tasks.
Form object
Label objects
TextBox objects
Button objects

13. First Set of Controls Forms, Labels, Textboxes, Buttons
Form - window that is displayed on the screen which contains other objects.
Label – displays text within a Form
TextBox – defined region used to accept text input from a user
Button – defined area that is used to start an event generated by the user
Note: Most of your application code will be associated with a Button Click event. If you double click on Control you will have the opportunity to view/modify the code or actions that will occur when the event happens.

14. Using TextBox for Input
GUI control object that is used to obtain keyboard input from the user Example
string name = txtName.Text;
int age = int.Parse(txtName.age);

15. Using Buttons for Events
Control object for user-generated events.
Write code behind for a Button Click

16. Using Labels for Output
GUI control object that is used to display text at a specific location on a form
Example
lblMessage.Text = "Some Message";
The displayed text is defined by the Text property of the Label
The data on the left side of the = operator must be a string

17. Using Textbox for Output
GUI control object that is used to display or obtain text at a specific location on a form
Example
tbMessage.Text = "Some text message";
Set the property ReadOnly to True to displaying text

18. Using Dialogs as Output
Message box
a small window (dialog box) that displays a text
Example
MessageBox.Show("Some text message");
MessageBox is a Class and not a control on a form
To create a message box you call the Show method on the Class.
The argument that is passed must be a string
