Hi Chronos,
The answer's yes and no.
You'll perhaps have seen pdfs, opened via links on a web page, displayed
in an Acrobat Reader within your browser, or image editors within a Word
document, etc, etc. The most ubiquitous example must be the Internet
Explorer browser. It seems that every program and its dog has a browser
window these days. That's not just a window though - it's Internet Explorer.
Each of these programs has been designed to be hosted within another
program as well as running as an application in its own right. They do this
by exposing their object model using a standard mechanism called COM. In
doing so, these programs are effectively becoming very meaty components
available as a resource for other programs.
Notepad is not such a program, as far as I know. And there are plenty of
other programs that aren't. Which is a shame.
Regards,
Fergus
