how to read rtf file in webBrowser control?

I've got a small app (both Access 2000 and VB6) that uses a web Browser control to navigate to a variety of sites.  I then parse the table info or text from the html and populate an Access table.

My problem is that one site that I need ends up delivering an rtf file.  My web Browser control loads the rtf file ok, but I can't seem to find the proper syntax, object properties, methods, etc. to then read the text.

Optionally, I could load the file to a RichTextBox control, but I can't seem to make the .LoadFile method of the RichTextBox control find the file on the internet site.


Any suggestions?

note: I've already tried "webBrowser.document.documentElement.innerHtml" or innerText or just "webBrowser.document.body.innerText" and gotten the error message:
"Object doesn't support this property or method."

It seems that once the rtf file is loaded, all of the normal webBrowser.document properties and methods are invalid.

To some extents, yes. i don't know if there is a "DOM" for rtf file format.

Well, as long as i can see, we could manage it like a word document, could you do a check?
(we have to use a better way to know which type of doc is but for testing, this would be enougth, wb1 is webbrowser control. We have to set a reference to microsoft word object library in the project)


Private Sub wb1_DocumentComplete(ByVal pDisp As Object, URL As Variant)
If (pDisp Is wb1.Object) Then
    If Right$(wb1.Document.Name, 3) = "rtf" Then
        Dim wrtf As Word.Document
        Set wrtf = wb1.Document
       
    End If
End If
End Sub

Do an inspection over wrtf var and see...

RTF could be read  to some extents as a Word Document
Better use Ark's code.
Cheers

I added some "On Error" statements and set the function values.

Thanks.
