how to trigger a delphi subroutine when a iframe windows is closed from a asp?

[Walter]

HI,

I have from a site a process info iframe, which is closed when the search process is canceled or finished.

How can I trigger a delphi subroutine from a TWEBBROWSER component when this iframe is closed.

SORRY that I post this delphi-spezific question here, but I think that might be a general JS event question.

thanks
