Hi UltimateCSP
Would he have been gambling all night long if we had not stopped him?
Agr hum ussy na roktay tou wo sari raat joaaa khailta rehta.

OR

Kia wo sari raat joaa khailta rehta agar ham usay mana na kartay?

Is it not interrogative? Please guide

Please translate these too, I shall be very thankful.

They would have walked to the station.
We would have slept in the tent.
I would have won the race.
He would have told her.
I would not have opened the door.
We would not have said that.
She would not have driven that fast.
Would he have done that?
Would you have travelled by train?
Would they have begun earlier?
