Access denied in WebBrowser control

I had the "smart" idea of replacing a RichTextBox control with a Webbrowser control, (never worked with html), so I created this class:

Code:

---

Imports System.IO
Imports System.Web

Friend Class MyBrowser
    Inherits WebBrowser

    Friend Shadows WriteOnly Property Texto() As String
        Set(ByVal value As String)
            DocumentText = value.Replace(vbCrLf, "<br/>")
        End Set
    End Property
    Public Property MyFont() As Font
        Get
            Return MyBase.Font
        End Get
        Set(ByVal value As Font)
            MyBase.Font = value
        End Set
    End Property

End Class

---

I enter the text on the webBrowser setting the Texto property, where I replaces all vbcrlf with "<br/>".

I wanted to replace a filename in the text, with a link to the filename this way:

Code:

---

"<A HREF=""javascript:window.open('file:///" & FileName & "'); void(0)"">" & FileName & "</A>"

---

(I pass that text to the webbrowser)

The problem is, At clicking in the link, it gives an error message box telling "Access denied".

I have found a workaround in this page
It advices:

But it looks like a bad hack. Is there a better way to do it?

JavaScript is only allowed to work in the domain in which it is loaded. That is why you receive the "Access denied" message. There is no way around this other than changing the security settings. But, doing that can open security holes to your machine through Internet Explorer.

I did not tested it on vista, but I are 100% fearsome that this would really mess the things in Vista.

some days ago, My boss Installed my program in a Vista Notebook, and I had a hell triyng to make it works.

Vista "virtualized" my code, and keep it installed with older files, even after uninstalling the application.

I uninstalled it, manually deleted the virtualized directories, reinstalled the application, and the older files where back!!. That is the dream of a virus programmer, and a hell for me.

That and the infamy of the autorun.inf are, as I believe, the worst "features" of windows.
