What's the difference?

[Dany]

I don't understand the difference between Present Perfect and Present Perfect Progressive.

Would you please explain me the difference between these sentences?

I have lived in Hanau since 1992.
I have been living in Hanau since 1992.

I have done my homework today.
I have been doing my homework today.


Thanks in advance,
Dany

The progressive or continuous tenses stress the ongoing activity rather than the completed (or uncompleted) event. They carry essentially the same meaning but are affected by the speaker's view (aspect) of the communication. Often the progressive is used to indicate increased interest, involvement, or politeness: 'Will you be having wine with your dinner?'
