Hello to everyone, I'm having a lot of problems while trying to achieve the following:

I'm developing a Twitter client, and I'd like the update status text field to detect when ever the user wrote a link (for instance if the user entered google.com) insert an hyperlink right away.

I've been working really hard on this, and so far I get the links inserted into a RichtextBox, but whenever a link is located twice in the RichtextBox the link is inserted again between the first link.

Since I'm using a string finder system to a string in the RichtextBox and then check if it is a link or not, whenever I get two same link sin the RichtextBox the first link is located by the search.

I would appreciate if any body could help me, I wouldn't like to make the users manually insert links into the twitter status update field.
