You might be able to find a converter that takes as input a stream and if so you might be able to use a stream from memory. I don't know of anything like that but that is something to look for.

Not to my knowledge. Is there some reason why you don't want to stream these documents to disk first?

Well, the RichTextBox can only handle plain text and RTF. So, you'd need to retrieve the varbinary field as a byte array and stream it to a disk file using File.WriteAllBytes. You'd then need to use a PDF to text or DOC to RTF converter to get the document into a form which can be displayed in the RichTextBox. If you have to do this programatically, then these two links may help: PDF to text ( http://www.codeproject.com/KB/string/pdf2text.aspx ) DOC to RTF ( http://www.codeproject.com/KB/cs/convertdocintootherformat.aspx )
