  -width => 500,
  -height => 900,

  -minsize => 500, 900,
  );

my $font = Win32::GUI::Font->new( -name => "Comic Sans MS", -size => 8
+,);
$main->AddLabel(-text => "Welcome ", -pos  => [ 10, 10 ],);
$main->AddLabel(-text => "Enter Host Name / IP : ", -pos  => [ 10, 33 
+],  );
my $t= $main->AddTextfield( -name => 'tfResults', -text => "", -pos  =
+> [ 125, 30 ],  -size => [ 100, 25 ], -tabstop => 1, );

  my $telnet = new Net::Telnet (   Timeout=>1800,    Errmode=>'die',  
+  ); 
  chomp $txt1; 
  $telnet->open($txt1);

  $telnet->waitfor('/login: $/i');
  $telnet->print('root');
  $telnet->waitfor('/Password: $/i');
  $telnet->print('dangerous');
  $telnet->waitfor('/# $/i');
  print "\nConnected to host :$txt1 ";
  
  $main->AddLabel(-text => " Enter custom cmd:",-pos => 100, 100 ,-siz
