Custom system variables

Anonymous — Wed, 06 Aug 2003 12:26:36 GMT

What hoops do I need to jump through to define a custom user variable that is similar to the USERR/I/Sx variables that I will use to store information about how custom entity styles should react. I have not found any documentation on system variables, but I have found the references to them in dbmain.h. Can I simply add a customized dbmain.h and the required code for my variable, or am I relegated to defining a function that does not define the data as persistent between drawing sessions?

TIA

i would do this:

your systemv.... is like a command. so if the user
enters the for exsample "myvar"

your arx ask for the input. maybe "1" or
"0"

after input of the user, your arx writes the input
to the registry - that's all i think.

You can't define your own custom system variables.

AutoCAD and most user applications use dictionaries
and xrecords to persist application data in a drawing
file.

You can also provide a command-level user interface
that allows the user to access that data as well.
