one go about getting the length from a div? How is this possible when CSS
is rendered in the browser?

I haven't been paying much attention today, so I'm not 100% sure what's
been said on this thread, but something I was thinking was that you
could put that string in a <div> and then check the width of the div.
There's a css property to give the actual width of the div as opposed to
the assigned "width" attribute so maybe that would help some. It'd be a
little extra work to get that variable into CF, but it seems doable.

I came up with this (you could easily turn it into a function):
font_obj = createobject("java","java.awt.Font").init('Tahoma',1,8);
font_metrics_obj =
createobject("java","java.awt.Toolkit").getDefaultToolkit().getFontMetri
cs(font_obj);
Pixel_Width = font_metrics_obj.stringWidth('My co-worker is mean');
I have a question though....I tried to do
createobject("java","java.awt.FontMetrics").init(font_obj) and it gave
me an error:
Unable to find a constructor for class java.awt.FontMetrics that accepts
parameters of type ( java.awt.Font )
Any ideas what I was doing wrong?
