JScript prend en charge l'utilisation d'événements mais pas la déclaration de nouveaux événements.
ExempleL'exemple de code suivant crée un contrôle PictureBox sur le formulaire et utilise l'événement Paint pour dessiner dessus.
' This example creates a PictureBox control on the form and draws to it. ' This example assumes that the Form_Load event handler method is connected ' to the Load event of the form. Private pictureBox1 As New PictureBox() Private Sub Form1_Load(ByVal sender As Object, ByVal e As System.EventArgs) Handles MyBase.Load ' Dock the PictureBox to the form and set its background to white. pictureBox1.Dock = DockStyle.Fill pictureBox1.BackColor = Color.White ' Connect the Paint event of the PictureBox to the event handler method. AddHandler pictureBox1.Paint, AddressOf Me.pictureBox1_Paint ' Add the PictureBox control to the Form. Me.Controls.Add(pictureBox1) End Sub 'Form1_Load Private Sub pictureBox1_Paint(ByVal sender As Object, ByVal e As System.Windows.Forms.PaintEventArgs) ' Create a local version of the graphics object for the PictureBox.
