Greetings Monks.
I used to be pretty good with perl, but after a few years of not using it (I don't have time for many projects outside of work, where I'm usually expected to use other languages) I've gotten a bit rusty. I've been trying to revamp our online in/out board using a Perl/Tk script ran through perl2exe, but I've run into a problem. There's a memory leak in the script and I can't figure out what I did wrong or if there's a better way to do what I'm trying to do. Can someone help? Here is the script:
#!/usr/bin/perl
#perl2exe_include Tk::Pane
use Win32::SqlServer;
use Tk;
use Tk::Scrollbar;
require Tk::Pane;
my $mw=new MainWindow;
# Main Window Elements
my $titleBanner=$mw->Label(-text=>"*Text changed to protect the innoce
+nt*",-font=>"Arial 12 bold")->pack();
my $testbutton=$mw->Button(-command=>\&destframe, -text=>"Refresh")->p
+ack();
my $statusFrame=$mw->Scrolled('Frame',-scrollbars=>"oe")->pack();
&destframe;
$mw->repeat(10000, \&destframe);
# Subroutine to get data from the DB
sub GetData{
my $sqlsrv=Win32::SqlServer::sql_init('*Deleted*','*Params*','*For
+*','*Security*');
my $batch=<<SQLEND;
SELECT firstname, lastname, status
FROM *Now I'm just being paranoid*
WHERE status is NOT NULL
SQLEND
my $result=$sqlsrv->sql($batch);
return $result
}
sub destframe{
# StatusFrame
# Get the data first
my $statusboard=&GetData;
#create a loop to populate the status frame
my $count=1;
foreach my $row (@$statusboard) {
my $status="$$row{status}";
if ($status=="1") {
$status="In";
}elsif ($status=="0"){
$status="Out";
}else{
$status="Not Set"
}
my $name=$statusFrame->Label(-text=>"$$row{firstname} $$row{la
+stname}")->grid(-row=>"$count", -column=>"1");
my $status=$statusFrame->Label(-text=>"$status")->grid(-row=>"
+$count", -column=>"2");
$count++;
}
}
MainLoop;
