Re^2: Start windows .exe

    Maybe you can help me a little further: I have the following code that just listens for files in the in directory. When it finds a file in the "in" directory it forks and then copies the file to the "out" directory where a system call to FTP the file takes place.

    My problem is that it forks just fine and it starts to FTP the files using the FTP_Client.exe program, however I get all these error messages ("Free to wrong pool ... C:/Perl/lib/IO/Dir.pm") before the program crashes.

    Can anyone see what I am doing wrong? I am new with PERL.

    THanks,
    Andrew
    My PERL code:
    use IO;
use File::Copy;
use Fcntl ':mode';
use warnings;
use Net::ftp;
use Net::Ping;
use Time::localtime;
use POSIX ":sys_wait_h";

system ("color 1f");

my $indir = ".\\in";
my $outdir = ".\\out";
my $expr = "*.*";
my $RemFile = "*.*";
my $d;


if  ( ! -e $indir ){
    print "$indir does not exist, attempting to create\n";
    mkdir ($indir, 0777 ) or die "Can not create $indir: $!"; 
}
if ( ! -e $outdir ) {
    print "$outdir does not exist, attempting to create\n";
    mkdir ($outdir, 0777 ) or die "Can not create $outdir: $!";
}



while(1){
  $d = new IO::Dir "$indir";
  tie %dir, IO::Dir, "$indir";
  foreach (keys %dir) {
            
    #if the expr is found in the InDir it will be FTP'd   
      if( ! S_ISDIR($dir{$_}->mode) && /^$expr/ ) {                
            
        
        
        if($pid = fork){
          waitpid(-1, &WNOHANG);
        }
        else{
          $RemFile = $_;
          #move the file to the out directory
          move( "$indir/$_", "$_");
          #chdir ($outdir);

                  print "Starting to FTP: $_\n";
          system("FTP_Client.exe $_");
              print "Finished: $_ \n\n";

              move( "$_", "$outdir/$_");
 
                  exit(1);
                }
        
    }        
    #sleep(5); 
  }
}

      Have you been able to pinpoint which line(s) are causing the errors? Also I would recommend using "use strict;"

      Here's a version that passes "use strict;" I declared a couple of variables and put 's around IO::Dir in the tie command. Also "use IO;" is depracted so I changed that to "use IO::Dir;". I can't give it a good test as I can't replicate your environment, but I hope this helps.
      use IO::Dir;
use File::Copy;
use Fcntl ':mode';
use strict;
use warnings;
use Net::ftp;
use Net::Ping;
use Time::localtime;
use POSIX ":sys_wait_h";

system ("color 1f");

my $indir = ".\\in";
my $outdir = ".\\out";
my $expr = "*.*";
my $RemFile = "*.*";
my $d;


if  ( ! -e $indir ){
    print "$indir does not exist, attempting to create\n";
    mkdir ($indir, 0777 ) or die "Can not create $indir: $!";
}
if ( ! -e $outdir ) {
    print "$outdir does not exist, attempting to create\n";
    mkdir ($outdir, 0777 ) or die "Can not create $outdir: $!";
}



while(1){
  $d = new IO::Dir "$indir";
  my %dir;
  tie %dir, 'IO::Dir', "$indir";
  foreach (keys %dir) {

    #if the expr is found in the InDir it will be FTP'd
      if( ! S_ISDIR($dir{$_}->mode) && /^$expr/ ) {


        my $pid;
        if($pid = fork){
          waitpid(-1, &WNOHANG);
        }
        else{
          $RemFile = $_;
          #move the file to the out directory
          move( "$indir/$_", "$_");
          #chdir ($outdir);

                  print "Starting to FTP: $_\n";
          system("FTP_Client.exe $_");
              print "Finished: $_ \n\n";

              move( "$_", "$outdir/$_");

                  exit(1);
                }

    }
    #sleep(5);
