Hello To solve the problem, i just changed the line :
$main->AddLabel(-text => "Hello, world"); by : $main->AddLabel(-name => 'montext', -text => "Hello, world"); Thanks a lot to Stuart and Glenn Thanks also to Erick, for the CODE samples provided May the Win32::GUI documentation be updated with this. _________________________________________________________________Nouveau MSN Hotmail : créez une adresse @hotmail.fr qui vous ressemble ! http://www.msn.fr/newmsnhotmail
