in reply to Tk/Perl Command

Looks like you confused a bit.
Actually what you 'retrying to do should certainly work, but you did some small mistakes in your code and in your understanding.

Look at some samples of codes.

Also it looks like you should do

$button_submit->configure(-text => 'helloo');
Your "$varname" is really not defined, as Perl explains to you.

Also remember that you have a method $widget->update; to redraw your GUI at a moment to reflect your current changes.

    In think you misunderstood me. I don't want the text on the button to change but I actually have a whole hash of Entry Boxes that need to have their information updated. Second, the varname was just an example. posted below is my current code (w/o the extra subroutines to save space)
    se strict; use Tk 800.00; use Mysql; require Tk::Frame; require Tk::TextUndo; require Tk::Text; require Tk::Scrollbar; require Tk::Menu; require Tk::Menubutton; require Tk::Adjuster; require Tk::DialogBox; # Main Window my $mw = new MainWindow; $mw->geometry('800x600'); # Frames Setup my $lf = $mw->Frame->pack(qw/-side left -fill y/); my $rf = $mw->Frame->pack(qw/-side right -fill y/); # Menu Bar Setup my $mb = $mw->Menu(-menuitems => &menubar_menuitems() ); $mw->configure(-menu => $mb); $mw->title("INSCO Inventory Control"); #Set Up Serial Query Information my $label_input = $lf->Label(-text=>'Serial Number: ',)->pack(qw/-si +de top/); my $tf_serial = $lf->Entry(-width=>30)->pack(qw/-side top/); my $label_space = $lf->Label(-text=>'',)->pack(qw/-side top/); my $returned = "";
    Right here is where I'm working.
    ##Set up query button my @info; my $button_submit = $lf->Button( -text => 'Search', -command => my \@info = \&get_data )->pack(qw//); print $info[1]; #Set Up Client Information my %field; my @names = (qw/tf_po tf_client tf_contact tf_phone tf_email tf_addres +s tf_city tf_state tf_zip tf_id tf_model/); my @sizes = ( 30, 30, 30, 30, 30, 30, 30, 30, 30, 30, 30); my @labls = ("PO:", "Client:", "Contact:", "Contact Phone Number:", "C +ontact Email Address:", "Contact Post Address:", "", "" , "", "Client + Specified ID", "Model"); my @pos = (1,2,3,4,5,6,7,8,9,10,11); foreach (@names) { my $position = shift(@pos); $field{$_}{txvar} = ''; $field{$_}{label} = $rf->Label( -text => shift( @labls )) ->grid(-row => '$position', -col => '0', ); $field{$_}{entry} = $rf->Entry( -width => shift( @sizes ), -textvariable => '', )->grid(-row => '$position', -col => '2', ); } # Start the main event loop MainLoop; sub get_data { my $entered = $tf_serial->get; my $dbh = Mysql->connect("host", "database", "username", "******** +") or die("Could Not Connect To Server"); my $query = qq~SELECT * FROM inventory WHERE serial='$entered'~; my $sth = $dbh->query($query); my @arr = $sth->fetchrow; return(@arr); }
