Lesson 14. The Form, the TextBox and the CheckBox.


The WinForms namespace has a lot of very interesting classes. One of the  
simplest is the Form class. Note that all programs in this lesson need to be
compiled with the option /r:System.dll  /r:System.WinForms.dll  
/r:System.Drawing.dll  /r:Microsoft.Win32.Interop.dll. The code bellow  
displays a gray form untitled "How do you do?".


//A very simple form
using System.WinForms;
class test:Form //class test inherit from the class Form
{
    public static void Main()
    {
    test HelloForm=new test();
    HelloForm.Text="How do you do?";//specify title of the form
    Application.Run(HelloForm);//display form
    }
}

Below I create a Form containing a TextBox. Note, that the TextBox and the  
Form are created separately and then attached to each other  with  
Controls.Add.

//A very simple form with attached textbox
using System.WinForms;
class test:Form //class test inherit from the class Form
{
    public static void Main()
    {
    test HelloForm=new test(); //create form
    System.WinForms.TextBox text=new System.WinForms.TextBox(); //create tex
tbox
    text.Text="This is a textbox";// Specify default text to be displayed in
side TextBox
    HelloForm.Controls.Add(text);//Attach TextBox to the Form
    Application.Run(HelloForm);//display form
    }
}

Bellow is a program which creates a simple CheckBox. I have changed the  
form's background color  with BackColor.

//A very simple checkbox
using System.WinForms;
class test:Form //class test inherit from the class Form
{
    public static void Main()
    {
    test HelloForm=new test();
    HelloForm.BackColor=System.Drawing.Color.Yellow; //set the color of the  
form
    System.WinForms.CheckBox check=new System.WinForms.CheckBox();
    HelloForm.Controls.Add(check);//Attach CheckBox to the Form
    Application.Run(HelloForm);//display form
    }
}


We will explorer other interesting classes belonging to WinForms namespace  
in the next lesson. In the meantime, try creating barebones applications  
using RadionButton and ListBox. Good Luck!
