"Don't have" and "Have no"

[San2009]

Hello, this is my first message, i want to ask a question.
Which is the difference between "Don't have" and "Have no".
I am reading a book and i saw the follwing sentences:
"I have no intention of lending you any money." also
"Mark has no chance of passing the exam."
In these sentences i can use "Don't have" and "Doesn't have", or better said, are the same "Have no" to "Don't have" and "Has no" to "Doesn't have".

Thanks for your answer.
Greetings
San
