Passive voice

[bhaisahab]

It's very nice of you all .Thank you so much.
And I will be really happy if you could give me a clear answer.

The clear answer, given by fivejedjon in post#2, is that it can't be changed into passive.
Or at least, as demonstrated by the other posters, not in any natural way. There is no reason to try to make that sentence passive.

. . . And I will be happy if you would answer my earlier question: Why do you want to put it into the passive?

As bhai says, there's no reason to do so.

So if an object follows a preposition,it's not a direct object?
That means in such cases we can't have passive voice?

We can in certain cases:

I gave Mary a book.
I gave a book to Mary.

Mary was given a book.
A book was given to Mary.

When a to+noun phrase acts as an indirect object (roughly speaking, the recipient of something), both direct and indirect objects can act as the subject of a passive construction. Note that the verb is transitive.
