in thread Suppress windows cmd for system command in Perl

Though I have not tried Win32::Process as I have some limitation to add new module in my application. But as you suspected the application is not creating the window as I am able to see the command that I gave in system in perl getting executed in command prompt window. I am able to rectify this in Linux by adding a extra argument $args5 = " 2>&1 >/dev/null"; which is passing the output to /dev/null and do not show on prompt. Similar way I want it in Windows so that it do not show command prompt and complete the command execution in background.

    Hello, start /B program > NUL 2>&1 is the windows equivalence of the shell syntax you refer. Anyway if you see the command executed in the prompt you can also add some line to show up who called it like in Re: Who called Perl? (solved) (if is relevant)

    Try invoking the java program directly from the C++ program.

    If you still get the pop-up; it means it is out of the control of Perl.

    If you don't; you have a way to prevent the problem.

      As per the design of my application I cannot invoke the java command from C++ program it has to be in Perl script itself.

        The point was to try help you to isolate the cause of your problem.
