What is the difference of Event-driven design vs Message driven design

I need to know what are the difference between the following design by simple example:

1) Event-driven design

2) Message driven design

I have checked the following url:

a) message driven vs. event driven approaches to application integration

b) Event-driven architecture

However, the discussion is not example based. My understanding is we can use message as event also. I know design pattern full example is difficult to given, so short example also welcome.

I am requesting a simple example based explanation.
