[bogdanc]

How to read by B4J PC user name or PC station environment variables?

    Log(GetSystemProperty("user.name", "default"))
    Log(GetSystemProperty("os.name", "default"))
    Log(GetSystemProperty("java.version", "default"))

see: https://docs.oracle.com/javase/tutorial/essential/environment/sysprop.html

Thank You!

I need also get a PC NAME.
PC is connected to network all PC's have a unique names in network.
So I would like to read this.

What happens on Windows 10? robot.SystemHostNameAndIP() should print a stack trace to the logs if it encounters an Exception. Can you post that stack trace?

What Java version are using in B4J on that machine? Which version of the jAWTRobot library are you using?

HI thanks for replay.

my java version: jre1.8.0_71
and I tried libraries jAWTRobot 1.45, 1.43,1.,40

Fixed according to this topic solution:
http://stackoverflow.com/questions/10382929/how-to-fix-unsupported-major-minor-version-51-0-error

I used a java jdk: 1.8... instated of 1.7...

I will verify that solution in my other PC win 7 on monday.
