Need Help Saving A Webpage (Internet Explorer)

Hello,

I got AutoIt to call up a web page and used

Send("{ALT}")
Send("f")
Send("a")

to call up the "Save Webpage" dialog box, but for the life of me I can't access the box. In addition to the direct approach, I tried these lines:

WinActivate("Save Webpage", "")
Send("Testfile")
Send("{ENTER}")

and:

WinActivate("[CLASS:Save Webpage]", "")
Send("Testfile")
Send("{ENTER}")

Neither of them worked to save "Testfile.htm" [the test name for the Webpage I'm trying to save] from the open dialog box.

How do I script it so that AutoIt saves the Webpage? Are there some commands that can access the dialog box, or should I use a different approach entirely?

As the lines above indicate, I just want to save the webpage raw - nothing fancy

Thanks.
