Hi "bzrqmy" ( Sorry, I do not know your real name )

Please note I have *moved* this thread from the AutoCAD General (http://forums.augi.com/forumdisplay.php?f=120) forum to this one, as I feel this particular forum is a more appropriate place for such a topic.

Thanks, Mike

Hi

Do you mean Modelspace Colour...


(getenv "Background") ;Get ModelSpace Background colour (Integer)

(setenv "Background" "8355647") ;Set ModelSpace Background colour (Integer)As the above uses an Environment Variable, you need to type the name as shown ie UPPERlower case.

If you do not mean Modelspace Colour, please explain some more.

Have a good one, Mike

Thanks Mike,

How do I manipulate the number 8355647 to give me white or grey?

No, there is not a system variable. But you can use vlisp code as shown below. This example function toggles the modelspace background color between white and black, and changes the crosshair color accordingly. Use of this code results in an immediate change of color compared to the changing of the environment variable.



(defun togbgcol ( / prefdisplay color)
(setq prefdisplay (vla-get-display (vla-get-preferences (vlax-get-acad-object))))
(setq color (vlax-variant-value
(vlax-variant-change-type
(vla-get-graphicswinmodelbackgrndcolor prefdisplay)
vlax-vblong
)
)
)
(if (= color 0)
(progn (vla-put-graphicswinmodelbackgrndcolor
prefdisplay
(vlax-make-variant 16777215 vlax-vblong)
)
(vla-put-modelcrosshaircolor
prefdisplay
(vlax-make-variant 0 vlax-vblong)
)
)
(progn (vla-put-graphicswinmodelbackgrndcolor
