Public Event Load As EventHandler


You can use this event to perform tasks such as allocating resources used by the form.

For more information about handling events, see Handling and Raising Events .


The following code example demonstrates how to use the SetDesktopLocation , Load, Activated , and Activate members. To run the example, paste the following code in a form called Form1 containing a Button called Button1 and two Label controls called Label1 and Label2.




Shared x As Integer = 200

Shared y As Integer = 200

Private Sub Button1_Click(ByVal sender As System.Object, _

ByVal e As System.EventArgs) Handles Button1.Click

' Create a new Form1 and set its Visible property to true.

Dim form2 As New Form1

form2.Visible = True

' Set the new form's desktop location so it appears below and

' to the right of the current form.

form2.SetDesktopLocation(x, y)

x += 30

y += 30

' Keep the current form active by calling the Activate method.


Me.Button1.Enabled = False

End Sub

' Updates the label text to reflect the current values of x and y,

' which was were incremented in the Button1 control's click event.

Private Sub Form1_Activated(ByVal sender As Object, _

ByVal e As System.EventArgs) Handles MyBase.Activated

Label1.Text = "x: " & x & " y: " & y

Label2.Text = "Number of forms currently open: " & count

End Sub

Shared count As Integer = 0

Private Sub Form1_Closed(ByVal sender As Object, _

ByVal e As System.EventArgs) Handles MyBase.Closed

count -= 1

End Sub

Private Sub Form1_Load(ByVal sender As Object, _

ByVal e As System.EventArgs) Handles MyBase.Load

count += 1

End Sub
