WebBrowser control is not displaying local HTML files

[Penfound]

Hi guys

I wasted a week so far reading and trying all the solutions I can find on the net only to find that they do no work.

I have a listbox that shows the filename of all files in a "show" folder. Clicking on a filename should display the HTML file in the webbrowser control.

Here is the code I'm using at the moment and the actual file location is "D:\The Penfound Project\family\show\1.html"

   Private Sub ListBox1_SelectedIndexChanged(sender As Object, e As EventArgs) Handles ListBox1.SelectedIndexChanged
        Dim SF, URLString As String
        SF = ListBox1.SelectedItem.ToString
        SF = myPath & SF
        WebBrowser1.AllowNavigation = True
        URLString = "file:///" & SF
        URLString = URLString.Replace("\", "/") 'this does not work
        'URLString = "https://penfound.org" 'this works
        Me.WebBrowser1.Navigate(URLString)
        WebBrowser1.Update()
    End Sub

When I click on a filename the program locks up wit ha blank browser area.

It's been a while, but I believe it should be file:// not file:///

And those should be the only forward slashes, the rest in the path should remain as back slashes.

At least using Chrome, opening a local HTML results in file:///C:/Users/FMS-VB/Documents/test.html in its address bar.

URLString = URLString.Replace("\", "/") 'this does not work

What is the value of URLString after this line?

Thanks for your input guys - unfortunately neither works.
Maybe MS will make one that does work in the next edition of VS

Define doesn't work. What error are you getting? Perhaps you should trap whatever exception you must be getting to lock up.

Using VS2013 on WIn 7, I can do

        Try
            Me.WebBrowser1.Navigate("file:///C:/Users/FMS-VB/Documents/test.html")
        Catch ex As Exception
            MessageBox.Show(ex.ToString)
        End Try

and it shows my test page. I'm thinking your URLString isn't exactly what you think it is or there is some kind of permissions issue or maybe something wrong with the HTML in the file.
