Re: two display devices?

Tech-Archive recommends: Fix windows errors by optimizing your registry

I beleive what Richard meant was that the apps need to know the display
coordinates. So when you use the APIs, you will set the window coordinates
to the apprpriate display. So if you have two displays that are 100 display
units wide and high (not real world but the math is easy) one would be from
(0,0) to (99, 99) and the other would be from (100, 0) to ( 199, 99) and the
virtual display would be from (0,0) to (100,99)

Hi Richard,
Thanks for your inputs.

One solution, used more than once, is to present the two adaptors to GWES
as
a single device, with the second adaptor acting as an extended display
surface.
At the app level, you need to know the areas of the display surfaces
corresponding to adaptor 1 and 2.
Normally applications use GWES API such as CreateWindowEx, rather than
using the display surfaces directly. If so, how can this be done?

I think two display devices can be exposed through two different
display drivers.
Then the applications should be able to use EnumDisplayDevices and
then CreateDC for a particular device.
After that, is there any possibility for the application to create a
window on a particular device? For ex: App1 wants to create its window
on the display1 and app2 wants to create its window on the display2.

regards
