Learn how to create a form using Notepad editor.

You can create a simple form by writing the code in an editor, for instance Notepad. Let's create a VB.NET program. SampleForm.vb, to learn how to create a form using Notepad editor.

Imports System
Class MyForm
    Inherits System.Windows.Forms.Form
        Friend WithEvents Button1 As System.Windows.Forms.Button
    Sub New()
        MyBase.New()
        InitializeComponent()
    End Sub
    Private Sub InitializeComponent()
        Button1 = New System.Windows.Forms.Button       
        Button1.Location = New System.Drawing.Point(100, 100)
        Button1.Name = "Button1"
        Button1.Size = New System.Drawing.Size(75, 23)
        Button1.TabIndex = 0
        Button1.Text = "Click Me"
        Button1.UseVisualStyleBackColor = True      
        Me.Text="Sample Form"
        Me.ClientSize = New System.Drawing.Size(250, 250)
        Me.Controls.Add(Me.Button1) 'Add Button to form
        Me.Name = "MyForm"
    End Sub

    'Click Event handler for Button1
    Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button1.Click
        MsgBox("You clicked Me")
    End Sub
End Class
Module Module1
    WithEvents frm1 As MyForm
    Sub Main()
        frm1 = New MyForm()
        frm1.Show()
        Windows.Forms.Application.Run(frm1)
        Console.Read()
    End Sub
End Module

In above code, a class is created that inherits from the Forms class. which belongs to the System.Windows.Forms namespace. The System.Windows.Forms namespace contains all the classes related to GUI based form development. Then, a control is added to the form, for instance button, and event handing code is added to deal with this control.
