  • 0

I am developing a small shutdown scheduler project in which i have to put the computer in "Stand By" mode. The command that i am using is

Runtime.getRuntime().exec("cmd /c Powrprof.dll,SetSuspendState ");

This command requires Admin rights which i don’t know how to get. Also while searching for previous answers i found i can use elevate.exe as

Runtime.getRuntime().exec("c:/elevate Rundll32.exe Powrprof.dll,SetSuspendState ");

Elevate.exe is doing the task but is consuming too much of time i.e. making the software slow. Is there any other speedy way? I am using Netbeans IDE.

    You have a few options

    A. Create a shortcut with admin priv.

    The shortcut will run cmd /c Rundll32.exe Powrprof.dll,SetSuspendState

    Your Java code will run the shortcut:

    Runtime rt = Runtime.getRuntime();
rt.exec("cmd /c start \"\" \"myshortcut.lnk\"")

    Right click the shortcut icon > properties > advanced > run as administrator

    B. Run the java process as administrator

    Again, create a shortcut and set to run as administrator. Any processes spawned will also have admin privileges. Your java code will run:

    rt.exec("cmd /c Powrprof.dll,SetSuspendState")

    C. Use JNA to directly call SetSuspendState routine. The Java process will require admin priv (like B), but you won’t have to spawn a process. If you like this, I can provide source code.

    D. Use wizmo utility: wizmo quiet standby
