Save CDocument programatically

How can I save an CDocument programatically, without to bring him to the top, only if I get a pointer to that document ? I mean if I have several document opened into a MDI app, and if I have a pointer to one of them, to save it without to turn them as active childs ?

Thank you.

What happens if you call OnSaveDocument?

I will try what you said and let you know what I have done. Thank you.

Is working now ... thanks.
