Re: How to Retrieve another Process' Window Title?

Just for completeness, I thought I'd drop through a note to say that the job monitoring is working well at present... *fingers' crossed*...

Here's the segment of code where all the magic happens:-

use Win32::GuiTest qw(FindWindowLike GetWindowText);

[...]

sub Check_Job
{
   my ($site_num) = @_;
   
   my ($buf, $num_windows);
   my (@windows);

   $buf = sprintf("^%s - Socks", $site_num);

   @windows = FindWindowLike(0, $buf);
   $num_windows = @windows;
  
   if ($num_windows == 0) {  # NO WINDOWS! Need to resubmit
      $st = 0;

   } elsif ($num_windows != 1) { # MULTI-WINDOWS!  Oops!!
      printf("%s: WARNING: There are %d Socks windows for site %d!!!\n
+", 
              $my_proc, $num_windows, $site_num);
      $st = 2;              

   } else {  # ONE-ONLY WINDOW - GOOD!
      $st = 1;

   }
   return($st);
} # end Check_Job

Many thanks, once again, for everyone's help.
