Invalid Page Fault With Win32::GUI Under Win98

Belgarion has asked for the wisdom of the Perl Monks concerning the following question:

I'm trying to experiment with Win32::GUI using ActiveState Perl 5.8.4 (build 810) under Windows 98. I'm trying to follow the examples in the Win32::GUI tutorial, but the first example in the tutorial is failing.

use Win32::GUI;
use strict;
use warnings;

my $main = Win32::GUI::Window->new(-name => "Main", -width => 110, -he
+ight => 100);

# This line is failing
$main->AddLabel(-text => "Hello, world");
$main->Show();

Win32::GUI::Dialog();
exit;

# terminate the message loop when the window is closed
sub Main_Terminate { -1 }
[download]

The AddLabel line is causing an illegal operation error with the following message:

PERL caused an invalid page fault in
module MSVCRT.DLL at 0167:78002fc5.

I installed Win32::GUI using the PPM system. If I removed the AddLabel line, the script runs and displays the empty window.

Has any one else experienced a problem like this? Is this a known problem, with a known work-around? Does Win32::GUI just not work under Windows 98? Thanks for any help you can provide.

That's a very old 0.0.558 bug. All controls must have a -name option, and that particular version happens to crash without it. Get your PPM here: http://perso.club-internet.fr/rocherl/Win32GUI.html#WinGui /J	[reply]
