Question

The Web browser’s Window.External object is always null!

To reproduce drop a web browser on a new winform and type:

Option Strict Off  Public Class Form1     Private Sub Form1_Load()         Handles MyBase.LoadMe.WebBrowser1.Document.Window.DomWindow.External.AddFavorite('http://www.google.com')     End Sub End Class 

Make certain you go to the Assembly Information dialog and check ‘Make Assembly COM-Visible.’ This is necessary.

I am lost as to why with a COM visible assembly the External object is always nothing.

Answer 1

Have you set the ObjectForScripting property to your host window? I think you need to do that for window.external to work.
