c# - How should i use VirtualScreenLeft and VirtualScreenTop -


in application need know size of monitors combined space, adjust size of window if goes big.

i found virtualscreenwidth , virtualscreenheight in system.windows.systemparameters , seems need. wonder virtualscreenleft , virtualscreentop , how should take in consideration? in scenarios values set not 0?

the virtual screen bounding box containing monitors of system. bounding box referenced @ 0,0 being upper-left corner of main monitor (the main-monitor defined in system properties).

this means bounding box can have negative numbers left/top values. example, lets have 2 1920x1080 monitors. main monitor set 1 on right (but level @ top), bounding box -1920,0,3840,1080 (x,y,w,h).

if move left monitor 500 pixels, bounding box becomes -1920,-500,3840,1580. important note areas of bounding box not visible user, if designing screen takes area both monitors have, aware may not set in rectangular shape. may not both same resolution.
