Hi. I need to set the system date from my application. It must works on Windows7 so the "cmd /C date" must be executed with Administrator privileges.
I tried do it that

Process p = rt.exec("runas /user:" + env.get("COMPUTERNAME") + "\\Administrator \"cmd /C date " + dateYYYYMMDD + "\"");

Then process ask me for password for administrator but it terminates befor i send it. exitCode() returns 1.

Have you some idea how can I do it?
Regards for you.

    At the very least, you need to read this and follow the advice it gives. That may or may not solve your problem, but it's a bare minimum.
