'Declaration
Public Property Handled As Boolean

Property Value

Type: System.Boolean
true if the event has been handled; otherwise, false. The default is false.

Set this property to true if you wish to display your own custom error message to the user, or suppress the error entirely.

The following code example demonstrates how to suppress a script error and display your own custom dialog box. This code example requires that your application host a WebBrowser control named webBrowser1.

Dim WithEvents ScriptWindow As HtmlWindow

Private Sub SuppressScriptErrors()
    If (WebBrowser1.Document IsNot Nothing) Then
        ScriptWindow = WebBrowser1.Document.Window
    End If 
End Sub 

Private Sub ScriptWindow_Error(ByVal sender As Object, ByVal e As HtmlElementErrorEventArgs) Handles ScriptWindow.Error
    MessageBox.Show("Suppressed error!")
    e.Handled = True 
End Sub
