。
All advice given to her was in vain.
Literal
Her [toward-へ] [possessive-の] advice [topic-は] all futile was.
A concise sentence combining the recipient marker へ with the nominalizer の to form 'advice directed at her.' 無駄 (むだ, 'useless, futile') is a very common and useful na-adjective. すべて ('all, entirely') modifies the predicate.
