in reply to Stop a .exe

Install Win32::Socketpair and do:

#! perl -slw use strict; use Win32::Socketpair qw[ winopen2 ]; ## Run the command and get a bi-direction pipe to it. my $pipe = winopen2( 'RunMe.exe arg arg arg' ); ## Fetch the results from the pipe my @results = <$pipe>; ## Send enter to it print $pipe "\n"; ## use @results here

    Not working. It keeps on waiting for pipe to close.

      Then you are using it wrong!

      Using the perl script as a substitute for your runme.exe:

      #! perl -slw use strict; printf "%030d\n", $_ for 1 .. 1e3; print "Press enter to exit";

      And this Perl script to run the above using winopen2():

      #! perl -slw use strict; use Win32::Socketpair qw[ winopen2 ]; ## Run the command and get a bi-direction pipe to it. my $pipe = winopen2( 'RunMe.pl' ); my @results = <$pipe>; print $pipe "\n"; print scalar @results; <STDIN>;

      The latter reads a thousand lines from the former, sends "\n" to it which allows it to end, and then prints out the number of lines read (1001 including the "Press Enter to exit prompt") amd waits. If you check the task manager you'll see that the child process has terminated:

      [12:05:50.87] C:\test>winopen2-test.pl 1001 [12:06:00.23] C:\test>

        This is my Script:
        use strict; use warnings; use Win32::Socketpair qw[ winopen2 ]; ## Run the command and get a bi-direction pipe to it. my $pipe = winopen2( 'PwrUsbCmd.exe 0 0 0' ); my @results = <$pipe>; print $pipe "\n"; print @results;
        It is not working. The Output from 'PwrUsbCmd.exe' is:
        PowerUSB is not connected Enter to continue ## Here I have to press enter to exit from this EXE +and it is not working.
