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!
