I have a Windows Form app (.net/C# 2.0 - VS 2005) which is using the
Flash ActiveX control to display Flash (.swf) files.  This works fine,
except for one issue.  I have an image 'behind' the Flash control that
I want to become visible as my Flash file fades out (i.e. becomes
transparent).  This is done in a web page, which uses the same Flash
control, by setting the WMode property to "Transparent".  I can take
the same Flash files and, for example, set the background color of the
web page to green, and the Flash files fade out and I can view the
green background.  When I set the WMode property of the Flash control
in my Windows Forms app, this does not work.  All I see is the white
'canvas' of the Flash control.

Just to clarify, I don't want to be able to, for example, see the
desktop 'through' my application.  I want to see what is on my form
behind the Flash control.  In my case there is an image (using a
PictureBox control) that I want to be visible.  Does anyone know how
this can be done?  Any help would be much appreciated.
