How to export Rich Text fields as HTML from Notes with LotusScript?

There is this fairly unknown command that does exactly what you want: retrieve the URL using the command OpenField.

Example that converts only the Body-field:

http://SERVER/your%5Fdatabase%5Fpath.nsf/NEW%5FVIEW/docid/Body?OpenField

Here is how I did it, using the OpenField command, see D.Bugger's post above

Function GetHtmlFromField(doc As NotesDocument, fieldname As String) As String
    Dim obj
    Set obj = CreateObject("Microsoft.XMLHTTP")
    obj.open "GET", "http://www.mydomain.dk/database.nsf/0/" + doc.Universalid + "/" + fieldname + "?openfield&charset=utf-8", False, "", ""
    obj.send("")

    Dim html As String
    html = Trim$(obj.responseText)

    GetHtmlFromField = html
End Function
