Webbrowser - Find what word was clicked

Is it possible to find what word a user clicks when he/she clicks inside of a webbrowser control, using C# I would like to highlight/select the word that is clicked, or at least know what the word is, so I can search my database for possible definitions. I would like it to be like when you double click a word in internet explorer (on a webpage), and it selects the word, but I only want the user to have to do it in one click. I thought about converting all my words to hyper-links, and then getting the active element from the Document, but I think that will take too much processing power for lengthy data displays. Any ideas will be helpful.

Thanks,

- Jon

    For anybody who wants to know, I found the answer to my problem.  With a little fiddling around, and help from MSDN, I found that you can select words with one click by using the following code, on the onmouseup event:

    IHTMLDocument2 doc = (IHTMLDocument2)webMain.Document.DomDocument;

    IHTMLSelectionObject sel = (IHTMLSelectionObject)doc.selection;

    IHTMLTxtRange rng = (IHTMLTxtRange)sel.createRange();

    rng.expand("word");

    rng.select();

    This will expand the selection by selecting the 'word', you can also do 'sentence', or 'character' (just replace "word").  Then you can just get the selection by doing:

    return rng.text;

    And there you have it getting the selected word. (You could collapse the range after you get the selected text, if you don't want the word to be selected.)

    Thanks,

    Yes, I know, I started that thread, and asked the same question, but nobody replied. Thanks though.

    There recently was a subject covered on handling the selected text of a WebBrowser control on this forum. Perhaps it will help you:
