change active color

[Anonymous]

How can i change the active color in autocad?

Usually is use something like Thisdrawing.activelayer = Thisdrawing.Layers.Item("layername")

Thisdrawing includes activelayer, activedimstyle, activetextstyle etc. but no activecolor.

Does anyone knows a way around it?

The system variable "CECOLOR" might be what you want?

Sorry but it's not clear which color you want to change.

If you change layer, for instance, will change the entities on the screen. But that may affect all entities on that layer... is that it?

Or do you want to change AutoCAD background color (usually black)?

Thank you, CECOLOR worked 🙂

I apologize if I am bothering you. I met the same question and found this post. However, being a self-studied newbie, I found what are the valid values, but I don't know how to call or set this system variable. Is it possible for you to show me an example of how to use this? One line of code should be enough. Thank you very much.

You can either use the Application.SetSystemVariable method or the Database.Cecolor property.
