Any and all help highly appreciated.  Thank you.

Answer 1

I have a blog entry that shows how to bold specific words in a Word document. That may help you get started:

Following code snippet may give some help:

            object missObj = Missing.Value;
            object path = @"D:\mydoc.docx";
            Microsoft.Office.Interop.Word.Application app = new Microsoft.Office.Interop.Word.Application();
            Microsoft.Office.Interop.Word.Document doc = app.Documents.Open(ref path, ref missObj, ref missObj, ref missObj, ref missObj, ref missObj, ref missObj, ref missObj, ref missObj, ref missObj, ref missObj, ref missObj, ref missObj, ref missObj, ref missObj, ref missObj);
            foreach (Microsoft.Office.Interop.Word.Range range in doc.Words)
            {
                if (range.Text.Trim() == "the text")
                {
                    range.HighlightColorIndex = Microsoft.Office.Interop.Word.WdColorIndex.wdDarkYellow;
                    range.Font.ColorIndex = Microsoft.Office.Interop.Word.WdColorIndex.wdWhite;
                }
            }

Thanks,

Hello

I'm saving word documents and even pdf document in a table of a SQL 2005 database

the database is fore-ended by a windows application in which the user may type a keyword and then using FTS I can search for the word inside the word document (which is stored in a varbinary(max) column)

what I need is to display the resulting documents as readonly in browser (it's a control that can be put on the win form) highliting the hits in yellow for example

you reply sounds interesting but is there a general way to highlight hits in any type of document (.doc, .xsl, .pdf,...)

Do you have any idea for doing that?

thank you

I suggest to use a c# word component Spire.Doc, I use it long time, quit good.
It supports search a word in a string and highlight the word .
May help to you.
