Thanks for all the inputs.
My application requires a moving images over other another images.
I've been directed in another direction that has worked, but I was hoping to
keep it simpler
If I slip a picture box under my moving picturebox, I wind up seeing all the
way through to the
form underneath. So it kind of defeats the purpose. That is why I liked the
simplicity of having an animated GIF as the base forms image. (although it
is a CPU hog)
Fortunately for now I can control the design of the application to prevent
this circumstance.
But it would be great to be able to put pictureboxA on top of pictureboxB
and set it so that the transparency
of pictureboxA showed pictureboxB instead of the root form.
Sort of like selecting how many layers you wanted to be transparent to.
