You can have your own ActiveX controls running in IE that can communicate
with Flash player.
If standalone, the you need to look at third party wrapper tools such as
SwfStudio, mProjector, Zinc, flaProjector etc.
Look at External Interface

Hi,
I?ve been looking around to see if I can find an answer.
We have a program written in C+ and VB is it possible to use Flash as an
interface with a program created in C+?
Has any one done this?
We like the way Flash works and looks and would like to use in with the
program.
Any help or direction would be appreciated.
Thanks

Thank you very much for the valuable information.
I was wondering if there are any functional examples or applications that are
currently utilizing the two languages?
I'd like to prove a point that Flash can be use as an interface with a program
built in C++
-The designers at Artsoft would rather use Flash-
Thanks

Try reposting in Flash Actionscript forum. Someone must have a pointer to
some examples.

Yes it can be done. If you can find the book "Flash MX Games, ActionScript for
Artists" by Nik Lever, Focal Press (ISBN 0-240-51903-5) , he has a very nice
tutorial for embedding a Flash swf file in a C++ Dialog program, with
inter-communcation between C++ and Flash.
