  1. We had our landlord ___ the broken window.

a) to fix
b) fixing
c) fixed
d) fix

I chose the the answer c) fixed but it was wrong. The right answer was d) fix
according to the site (englishvocabularyexercises.c … atives.htm)
I think the causative form of have >> have + object + past participle of verb and it is passive form. I m so confused to use the passive and active form of causative.
I don’t know where to use >

have + object + past participle
We had our landlord fixed the broken window.

AND

have + object + present of verb
We had our landlord fix the broken window.

Please help me to understand it properly.

It is never right to say
We had our landlord fixed the broken window.

It would be correct to say
Our landlord fixed the broken window.

Once you add ‘we had (someone)’ to the sentence, you need to use the present tense form:

We had our landlord fix the broken window.
We made our son apologise for the incident.
I had my wife visit the shop on my behalf.
I made the dog sit on the rug.

3

No, that’s not the present tense, it’s the infinitive.

Staying with it a bit longer, I wonder if you agree with a site bringing on examples of causatives:
“Have (give sb the responsibility to do sth) —I had John fix the car. I had my hair cut.
Get (convince or trick sb into doing sth)–He got the mechanic to repair the machine. She got him to read more.”

Do you really distinguish them that way? I mean ‘convincing\tricking the mechanic into repairing’?

I feel I’ve got something to add. Perhaps what originally looked misleading for the poster could be clarified by that:
HAVE + PERSON + VERB (base form) 
HAVE + THING + PAST PARTICIPLE OF VERB

Examples of grammatical structure #1:
I’ll have my assistant call you to reschedule the appointment.
The businessman had his secretary make copies of the report.
Examples of grammatical structure #2:
I’m going to have my hair cut tomorrow.
We’re having our house painted this weekend.
Bob had his teeth whitened; his smile looks great!
My washing machine is broken; I need to have it repaired.

I don’t think ‘I had my hair cut’ is an example of causative.
The poster says: I don’t know where to use > have + object + past participle

He is rather confused with the causative use of ‘have’. He may just note that there is yet another construction: have/had + something + passive perfective participle.

So he could alternately say: We had the broken window fixed by our landlord. (As you suggested later)
