how to make passive in different ways

:If you need alternative ways to form the passive voice, here is the answer
You can form sentences that are passive in meaning but not in form by using the verb to get or the verb to have in place of the verb to be. These constructions often describe situations where we want someone else to do something for us or where we are going to hire someone else to do something for us. The subject is active, but he is only doing the "getting". It is the unnamed person who is gotten who will perform the action of the main verb in the sentence. That second person is not explicit in the sentence when the sentence has a passive meaning. We are more interested in the result of the activity than in the person that performs the activity

I must have my hair cut-
?When are you going to get that window mended-
We're having the house painted-
