Controlling java applet
 

I have written a macro below that opens up an instance of internet
explorer, logins in to a site with a username and password, navigates
to the appropriate part of the site and saves a) some text from the
site and b) some of the html from the site using the innerHTML and
innerTEXT properties

I am now stuck with the last part. I can navigate to the correct area
of the site. This brings me to a java applet which shows a bar chart
which changes as you drag a slider (at different ages) up and down. I
need to take screen shots of the graph at various different ages but I
don't know how (or if its possible) to move the slider from the applet
using VBA. Can anyone help please?
