File Diff /Merge Application in VC++

I need to develop File Diff/Merge utility in VC++ (MFC or ATL) based. Application will take 2 or 3 file names with path and will show the difference like WinDiff in different color coding. It will also allow to jump directly to change and allow user to merge the changes manually or automatically. User can optionally edit the file before merging. This bid is useful for coders who have prior experience in this area and already has developed libraries or code to build this functionality fast and cost effective. ## Deliverables 1) Complete and fully-functional working program(s) in executable form as well as complete source code of all work done. 2) Complete ownership and distribution copyrights to all work purchased. ## Platform Any Windows, deliverables are VC++ source code without needing any other library or component.
