Teddy, sorry, was OOO yesterday so i didnt get this, but zentara beat me to the punch :) Basically just scanned the system processes for my process. If it was not running, I would restart it. Of course, zentara's solution is a lot more cleaner and more efficient than mine, so I wont bother posting my example. chris btw the proc:processtable mod is pretty neat, i didnt realize it existed till that post :) -- --- Just Your Friendly Neighborhood _SPIDEY_ -- To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]
Non-caching META-tags
When writing HTML, the trick I normally use to ensure that images etc are
definitely the latest version, and not the cached version, is the
following:
META http-equiv=Cache-Control content=no-cache, must-revalidate
META http-equiv=Pragma: no-cache
I want to do the same thing in a page generated by perl/cgi, i.e something
like:
print $q-header,
$q-start_html(-title='My new page',
-meta={'http-equiv'='Cache-Control'
'content'='no-cache,must-revalidate'})
-meta={'http-equiv'='Pragma: no-cache'});
but this gives
String found where operator expected at test.pl line 20, near
'Cache-Control' 'content'
How does one get perl produce the equivalent of the META tags above?

are you missing a comma and a greater than sign there?
-meta={'http-equiv'='Cache-Control',
^
'content'='no-cache,...' }

CGI.pm doesn't support http-equiv meta-tags, according to the documentation. What about something as simple as: print _META_TAGS_; META http-equiv=Cache-Control content=no-cache, must-revalidate META http-equiv=Pragma: no-cache _META_TAGS_ IMNSHO, CGI.pm shines when you're getting form input, printing forms or tables dynamically, or messing with cookies. With something as straight-forward as printing out meta-tags and headers, though, I personally feel it's drastic overkill.

console window
when i ran perl programs using windows 98 operating system, i double clicked on the program name in windows explorer. i kept the program files right in the C:\Perl directory. the programs would open a command prompt type console window and execute. the console window remained open until i clicked on the X to close it. now i have a new hp pavilion pc running windows xp. everything else being the same, when i run the perl programs from windows explorer, the console window opens, executes and closes before i can see anything in it. i realize that if i open the command prompt, i can see the program results but i would like to be able to run the programs directly from windows. i have tried changing the suffix from .pl to .bat(using pl2.bat). the results are the same either way. thank you gary rocco [EMAIL PROTECTED]
Variable method invocation
Not sure if this is the correct place to ask, partly because I'm not sure
where the problem lies.
Environ: Winnt, ActiveState Perl, ImageMagick, Apache.
Script uses CGI standard. I am attempting to access various methods from
Image::Magick, some of which require no arguments, 1 argument, several args,
and I want to access methods with arguments as follows:
$method = param(meth); # works, grabs 'Rotate', 'Convolve' etc..
$method_args = param(margs); # works also - to a degree
$result = $image- $method ($method_args);
When 'method' requires 1 argument (like Rotate - requires a numeric value in
degrees),
passing the method name and 'simple' argument (like $method is 'Rotate' and
$method_args is 90) the form:
$result = $image- $method ($method_args);
works without a hitch (and I must admit I am delighted...). When the method
can accept more than one argument (like Border which requires a 'geometry'
string like '2x2' and -should- accept a second argument for color in the
form color='red' the second argument is ignored.
Can anybody tell me what is happening, why the 'supplemental' arguments are
being ignored?
TIA and any feedback including RTFM itsat (one word meaning it {the FM} is
at ) is appreciated.
David

Re: Variable method invocation
Wiggins, Tried it, no joy! Even tried a reference to the array, no workie! Because this -looks like- a hash $image-Border(geometry='5x5', fill='red'); (and works) I will try to approach it as a hash. This is one of those 'exercises' where I am trying to replicate functionality I have seen on the web (specifically Image Magick Studio). If this leads to a compact, functioning program I will make it available to all interested. Thanks for your response!

listing perl modues on system

Re: listing perl modues on system
Jerry,
I use this to track the modules I have installed for an ActiveState perl
install on WinNt.
#!E:/Perl/bin/perl -w
use ExtUtils::Installed;
my $instmod = ExtUtils::Installed-new();
foreach my $module ($instmod-modules()) {
my $version = $instmod-version($module) || ???;
print $module -- $version\n;
}
