I see you've already answered your own question regarding the use of
Win32::GUI over Win32::API, but FTR, if you wanted to use Win32::API the
syntax would be
use Win32::API;
my $WM_CLOSE=16; # you must assign this value manually
my $findWindow = Win32::API->new( 'user32', 'FindWindow', 'PP', 'N' );
my $sendMessage_lParam_as_number = Win32::API->new( 'user32', 'SendMessage',
'NNNN', 'N' );
my $sendMessage_lParam_as_stringpointer = Win32::API->new( 'user32',
'SendMessage', 'NNNP', 'N' );
my $windowToClose =
$findWindow->Call("PGPtray_Hidden_Window","PGPtray_Hidden_Window");
$sendMessage_lParam_as_number->Call($windowToClose,$WM_CLOSE,0,0);
