Learn Hardcore Vietnamese: Bạn có đến thư viện vào sáng mai không? - Are you going to come to the library tomorrow morning?

Bạn – you (used for a friend / peer)
có – literally have / there is, but here it works as part of a yes–no question pattern
đến – to come, to arrive
thư viện – library
vào – into; with times it works like in / on / at
sáng – morning
mai – tomorrow
không – no / not; at the end of a sentence it is a yes–no question particle

A very literal gloss would be something like: You (có) come library at morning tomorrow không?

Why are both có and không used? How does this make a question?

Vietnamese often forms yes–no questions with the pattern:

[Subject] + có + [Verb / Adjective] + không?

So:

Functionally this equals English “Do / Will you … ?”

So có … không here is a grammatical frame for yes–no questions, not two separate content words that both need to be translated.

Does có still mean have in this sentence?
