Re: 2 Qs re JS scripting

I have an application that presents it user interface in an MDI OLE'd IE6
browser window. The app that controls this interface calls .js files for
given events. Thus on event A it would call A.JS from its directory.
What I want to do is take parameters that are available to the A.JS and open
a local html file, I will call this A.HTML, A.HTML will be opened as an MDI
window within the main app.
I want to take the parameters that are in available to A.JS open the A.HTML
(I can now do the open bit as the main app has an API call to open an html
file as an MDI window) perform some tasks around the parameters based on
what the user clicks on in the displayed A.HTML page, after they have
clicked on X I will do some stuff and then the page should close returning
to the hosting application. but before the hosting application takes back
control i.e. when A.JS ends I need to make another call to the hosting
application. thus I wanted to watch A.HTML and pause A.JS until A.HTML is
closed.
All of this local, no webserver local or remote all of this is just flat
files!
Thanks for everyone's help and input thus far.
I Hope I have made it clearer!
