Almost certainly. What error did you get? Have you got Win32::NetAdmin
installed?

I have used Text::vFile::asData to convert iCal MIME parts to something
I can read. It handles all the v-type formats (vCalendar, vCard, ...),
but that flexibility makes it a bit cumbersome to use. Here's a snippet
from my script (whole script available on request if anyone wants it):

Strawberry 5.16 seems not to understand

use Win32::NetAdmin;

I guess that's because Win 7 doesn't have a Win32, but I may have
misunderstood.

Luckily Perl is blissfully independant and ignorant of any OS version.
Therefore unless you are doing some very specialized coding for a
specific OS-version there is no need for any OS-version specific
learning.

What is special about Win 7 that makes you think you need a different
book? Concentrate on learning the basics first; then, later, if you need
to, you can find out how to do system-specific stuff on your system.

Then take 4 days off at full pay, come back, and claim that during those
4 days you developed that piece of code. Problem solved.

I'm completely certain that in these anomalous cases, I'm definitely not getting the response I expect. The problem with this error message is that it gives me absolutely no clue where in the script this is happening. I'm guessing that our back-end server gets confused in some cases, but it's hard to diagnose when I don't know what URL was being attempted, or where in the script it was done.

I have "Learning Perl on Win32 Systems" by Schwartz, Olson and
Christiansen. It's the right level for me, but I need something for
Windows 7 specifically, and suggestions?

I did not think about that variable idea, thanks.

I know the kind of thing I try to protect my code against is very dirty.
I try my best, I'll document everything else, indeed.

Once again, I agree about that idea, but I'm not allowed to do that either.
I'll take a look to PAR, you described some interesting stuff (for other
developments).

Thanks :).

*If* the die is executed while a scope with a localized $@ is active,
it will change the value of the localized $@ and this change will be
undone as part of the stack-unwinding which happens when exiting that
scope.

So copy the code out of Try/Tiny.pm into your own script.

More generally, this sort of restriction can usually be worked around
with a little thought, and it's usually worth doing so. For instance,
PAR::Packer provides the pp utility, and pp -P will pack a script and

Quoth Adrien BARREAU <adrien.barr...@live.fr>:

If you must work around this sort of thing, you can do so by using your
own variable:

sub make_call {
my $alarmed;
$SIG{ALRM} = sub { $alarmed = 1 };
try { ... }
catch {
if ($alarmed) { ... }
