Direct X screen shots capturing

I'm trying to write a DirectX program that captures a screen shot that includes any graphics created by other DirectX programs, in particular those with overlays.  But I've read that EnumSurfaces only can find existing surfaces owned by my process - which seems to match my experience.  

Is there some way around this?  For example, has anyone tried injecting DirectX code into other processes?  Written a special video driver to access the video memory directly?   Are there obvious problems I should think about before embarking upon this?  

Thanx

Hi,

I don't see how to circumvect this.
DirectX is Microsoft propertary code. Graphics cards makers as ATI, Nvidia, MSI, etc, have their own drivers, so there are at least two black boxes in the way.
Even if we were able to read directly video memory content, we have nothing to do with it, because format, maping, way of rendering, are unknow to us.

Sounds that what you have discovered is the best we can do.
