How do I detect the current security-context from a Java Applet -


I have an applet that needs access to the host system (for launching programs, queries for system settings etc.) ) The applet has been signed, and when the end user accepts my certificate, the applet's end-user is free to do whatever he wishes on the machine. If the end user rejects the certificate, the applet is still running, but it can not perform duties.

I have used System.getProperty ("java.io.tmpdir") to determine whether the applet is restricted. It works fine with Windows, but somehow Java behaves differently on Mac OS. (I thought that part of the point with Java was a system-independent language with well-defined behavior - but I end up writing a specific code for Mac and Windows - like I do with C ++) .

Is there a reliable way to define security - is the inside of the applet running? 

  public stable boolean is trusted (security manager security = System.getSecurityManager); If (security == zero) {return true; } And {try {security.checkPermission (new AllPermission ()); Back true; } Grip (Security Exception AX) {return false; }}}

(General disclaimer: not tested, not compiled)

Eclipse CDT variable colors in editor -

I hope this is a good question to ask here. This programming is related, so I thought it would be better than the superuser, so I am using the CDT C ++ Eclipse plugin. I know how the editor changes colors for some things But is there a way to do that all the variables are different colors? For example in KDEValue, it sets the local variables and square variables in different colors and bold square squares. Can I copy it to CDT? Eclips provides some level of color customization for text editor syntax You can see it on the following: There are many elements, including the Window> Preferences> C / C ++> Editor> Syntax color code that can be changed, assembly, Comments, Preprocessor and Doxian Under the code, it is possible to change the color of some variable types, such as global variables, local variable announcements, local variable references, and parameter variables. But I do not think the code is capable of changing the color of each variable declared....
