ok this is really annoying.. i can't get any output from any program i execute through a perl script using acitve perl.. have u guys tried this.. if u were successful.. how did u do it? note: everytime i tried doing this, the program i executed always prints to the console. how annoying! And the variable to which i'm storing the output to, is empty!   |

what code are you using to run the command? most things will return the return value of the program. $theoutput = `echo hello`; should = "hello" |

hmm, odd, echo appears to works. so does ipconfig.exe javac does not work.. i guess perl (or maybe jsut ActivePerl) can't catch output from a java program? |

it could be a STDERR, STDOUT problem. Try redirecting STDERR to STDOUT, and see if that helps (add this to the end of your command '2>&1' pretty sure thats it, and I'm pretty sure this works in 'nix, and windows) |
