I want to access the back and forward button present in IE? I mean I want to traverse a Specific URL instead of the Previous url which has been generated by clicking 'BACK'. So, How can I do this? How can I implement the Travel Log Interfaces and interfaces like IDocHostUIHandler Interface in c#? Can anyone suggest for doing this?
