I'd like to know if anyone of you would be interested in being payed ($$$) to program a BNF like parser.
Intermediate to advanced programmer skills required because the project deals allot with pointers and memory updates and
inter-mixes c/c++/perl code. Anyone interested visit http://www.angelfire.com/cppcode/blog/spec_0.txt for futher details

Actually i started learn about web designing approximately six months ago..that's why i don't have the proper knowledge of languages.I am not sure that this is the right place or not for my request but i want to know about Perl..can anybody define the Perl..
Thanks in advance.

onmouseover in perl/cgi script

As it's server-side only, Interaction between your Perl script and the browser is limited to processing & sending content (basically, the avenue of HTTP). It has no control over client side behavior, such as DOM events (mouseover et al.). You can use Javascript (as you asked), though a CSS-only approach may also work, depending on how the document is structured. (aside: this means you should ask in the DHTML forum, not the Perl forum. By picking the right forum, you're more likely to get readers who know the answer to you questions.)

I'm assuming that when you ask "should i use text/javascript in order to enable the onmouseover element?" you also meant to ask "How would I ...?" An even better way of asking for help would be to say what you want to do and why; e.g.: "I want to make some text visible at the bottom of a web page when the mouse cursor is over an image. How could I achieve this? This is what I've tried so far: [...]". (As patronizing or smarmy as it may seem, learning how to ask questions makes it easier for others to answer your question and helps you understand the problem more, sometimes resulting in your discovering the solution.)

All the samples below use the following CSS style sheet.

Code:

.hidden { visibility: hidden; }
.capton {
position: absolute;
bottom: 0px;
}

The CSS-only way requires both the image and the text to be the children of an element whose content box contains only the element. If you want to support IE6 (which, sadly, we have to for now), the parent element must be an anchor:

Code:

If you use Javascript, I recommend having the event listeners add or remove a class from the text node rather than directly manipulating its style. It won't matter much in the example below, but when you want to dynamically apply a more complex style, it's a much cleaner approach.

Code:

That should get you started.

Are you still having problems with your guestbook? It doesn't look it, but I could be missing something. You might want to look for a script that supports captchas to prevent spam.

That's not enough information. Please post the section of the code that performs the csv parsing, a sample csv file and the result that you get when running your script on the sample file.

A Google search for "tripod perl" turned up a guide to CGI support on Tripod. It wasn't hard to find.

Notepad is fine for this.

I would not rely on any 'WYSIWYG' editor for any server type programming.

Sorry, Jasper, I wasn't clear at all there.

FOREACH... END sure looks like PERL to me.

The [% %] delimiters tell the server to parse the code between the delimiters as PERL, but they appear to be part of a proprietary template code.

In fact, I think we're looking at code used with the PERL Template Toolkit module.

There are variable created somewhere outside of the posted page, and where you see code like this:

Code:

The value of "context_id" (defined in PERL somewhere other than the posted page) is written into the HTML document.

Where you see:

Code:

[% FOREACH action = action_list %]
<div id="desc[% action.name %]" style="position:absolute; visibility:hidden;">
<p>Action Description: <br/>[% action.desc %]</p>
</div>
[% END %]

A loop is created which runs through each "action_list" (array) item, assigning the value of the item to the variable "action", and writing the code between [% FOREACH...%] and [% END %] to the HTML page.

So, a <div> is created for each item in the action_list array, and the action_list array is defined elsewhere.

Yes, PERL can be used to access a database, and the most common DB extension for PERL is the BerkeleyDB extension.

Web-based database modifications are most often accomplished through the use of an online form which points to a form-processing script via the action="" attribute of the form:

Code:

Basically, the script page is either all script and no HTML, which processes the form then forwards the user to another page (often a confirmation page), or a page with mixed script and HTML, which serves as both form processor and confirmation page.

Note: The .cgi extension should be used for script-only documents.

Some common ways of managing a database are (1) Working directly on the database (such as opening an AccessDB in Access), (2) creating a web-accessible management interface, usually a form-based method, and (3) using a pre-built web-accessible management tool (for PHP/mySQL, PHPAdmin is the most common tool, but I don't know what's used for PERL).

A more hardcore method is to create script pages, upload them to the server, then run them by typing their URL in the browser. But, you really have to know what you're doing there.

So, "where" you modify the database depends on what you're trying to accomplish.

Hope that's a LOT clearer.

Did you mean to put this in Perl?

CGI / Perl coding problems setting code

Hi e1, I hope that y'all can help me. Since I don't exactly know the problem, I'll tell you everything. 1st off CGI/Perl dummie here...I get by on my HTML especially with the help of these forums - Tanks e1...
Now, I downloaded an "E-Card" program. walked my way through the limited instructions it gave me. I used their template, to create my page, at thelordsflock/karaokecares.com/ecards.html
I put all the files where they're supposed to go, (I think) and I finally get the page pulling up, the images showing, but when you select one the click the "next" button, it brings you back to the same page...over and over and over.
If you don't want to "view source" here is the code I'm using:

<html>
<head>
<style>

</style>
<title>Send An E-Card</title>
</head>
<body>

In the " <form method=post><input type=hidden name=command value="edit"> " line, I've tried changing value to edit.html, cards/edit, cards/edit.html to see if that would direct me to the next page, which is supposed to be (I think) thelordsflock.karaokecares.com/edit.html

Please, PLEASE, Please make your answer as DUMMIE friendly as possible, as I don't know a lot of the terminology. Thanks so much and God bless

*****Addition*****
I have tried a couple of different things, 1: I found out that if I add an "action" in the form area, I can get it to leave the page and go to the next one, BUT it does not carry over the "selected" information with it. I went and checked the "test" code from the programmers and looked at their "veiw source" code, Their code works and does NOT modify the form area with an "action" segment...
My webhost DOES support Perl and CGI in fact this is their provided information to help me(you) maybe...
Hosting OS Proprietary *nix
PHP version 4.4.1
Perl version 5.8.4
MySQL version 4.0.24
MySQL hostname if this is needed, let me know I edited it out
Perl path /usr/bin/perl
Sendmail path /usr/sbin/sendmail (SMTP is disabled for your hosting account)
CGI-BIN path not required (You can run CGI, Perl scripts from any domain/subdomain folder)

I hope this additional information helps....

I found the answer with

Code:

$SIG{ALRM} = \&timed_out;
eval {
alarm (10);
$whois_info = `whois $domain`;
alarm(0); # Cancel the pending alarm if whois responds.
};
if ($@ =~ /GOT TIRED OF WAITING/) {
print " Whois timed out: $@ ";
}

sub timed_out {
die "GOT TIRED OF WAITING";
}
