refactoring - Eliminating code duplication in a single file -


Unfortunately, a project on which I am working recently has a large amount of copy-paste code, even in single. Files Can any device or techniques detect repetitious or near-duplication in a file? I'm beyond comparison 3 and works well to compare different files, but I'm in loss to compare single files.

Thanks in advance.

Edit:

Thanks for all the great tools! I will definitely check them out.

This project is an asp.net / c # project, but I work with many languages ​​including Java; I'm interested in the best tool for deleting duplicates ( for any language ).

Check out receives duplicate code which is central to extracting a location.

I generate many Ajax form in a table such as: & Lt; Input type = "submit" name = "activity" value = "add activity" / & gt; & Lt;%}% & gt; & Lt; / TD & gt; & Lt; / TR & gt; & Lt;%}% & gt; So far so good. When I post one of those forms, it gives a partial view in a div, and in this new partial view a new Ajax Beginnform (which is not in Genesis form) This second Ajax Beginnorf is exactly like the ones I got on the table, but when I post it, I do not get the "Ajax Post", but a normal post that sends me to a new page, I do not know whether the two Ajax forms What is the reason for the difference between, why is it the "dynamically generated" Ajax form behaves like a normal HTML form? By the way, I know that I can do it in different ways using javascript, but I would like to understand whether it can only be done using MVC helplars and Ajax lib...
