How to fill in SaveAs Dialog box and press OK?

I am using the axwebbrowser. I have automated the navigation of a website.

The program presses one of the buttons on the website and "Open/Save/Cancel" Dialog appears.


How can I programatically press the Save and then fill in the name and click the save button

Seems to me that will be difficult and involve much API mojo. I'm pretty certain there isn't a core .NET way to send mouseclicks to windows that don't belong to your app.
