        frmHelp.ShowDialog()
End Sub

Test the application

3. Build graphical interface elements by using the System.Drawing namespace

Start a Windows Application
Right-click the middle of the form and click View Code
In the class Name combo box, select (Form1 Events)

In the Method Name combo box, select Paint and implement it as follows:

Private Sub Form1_Paint(ByVal sender As Object, ByVal e As System.Windows.Forms.PaintEventArgs) Handles MyBase.Paint
        Dim PenRed As New Pen(Color.Red, 2)

        e.Graphics.DrawRectangle(PenRed, 20, 20, 350, 270)
End Sub

Test the application

Save the application

5A. Load controls dynamically

Start a Windows Application named MCAD5
Right-click the middle of the form and click View Code

In the top section of the form, declare a Button variable named btnSubmit

Public Class Form1
    Inherits System.Windows.Forms.Form
    Dim btnSubmit As Button

In the New() constructor of the form, type code to dynamically create the button

Public Sub New()
        MyBase.New()

        'This call is required by the Windows Form Designer.
        InitializeComponent()

        'Add any initialization after the InitializeComponent() call
        btnSubmit = New Button
        btnSubmit.Text = "Submit"
        btnSubmit.Left = (Me.Width \ 2) - 40
        btnSubmit.Top = 40

        Me.Controls.Add(btnSubmit)
End Sub

Save and test the application

5B. Add the code to a control

Create a Sub procedure as follows:

Private Sub Submitter(ByVal sender As Object, ByVal e As EventArgs)
        MsgBox("Your employment application has been submitted. We will get back to you")
    End Sub

In the New() constructor of the form, specify the code to handle the event of the dynamically created control:

Public Sub New()
        MyBase.New()

        'This call is required by the Windows Form Designer.
        InitializeComponent()

        'Add any initialization after the InitializeComponent() call
        btnSubmit = New Button
        btnSubmit.Text = "Submit"
        btnSubmit.Left = (Me.Width \ 2) - 40
        btnSubmit.Top = 40
        AddHandler btnSubmit.Click, AddressOf Submitter

        Me.Controls.Add(btnSubmit)
End Sub

Test the application

4B. Write code to handle control events

Open the MCAD4 application

Double-click each radio button and implement their events as follows:

Private Sub rdoSmall_CheckedChanged(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles rdoSmall.CheckedChanged
        Me.txtPizzaPrice.Text = "$7.55"
End Sub

Private Sub rdoMedium_CheckedChanged(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles rdoMedium.CheckedChanged
        Me.txtPizzaPrice.Text = "$9.35"
End Sub

Private Sub rdoLarge_CheckedChanged(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles rdoLarge.CheckedChanged
        Me.txtPizzaPrice.Text = "$11.25"
End Sub

Double-click the Close button and implement its Click event as follows:

Private Sub btnClose_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles btnClose.Click
        End
End Sub
