I have installed apache for windows vista. I have configured apache to use Lister:8888 in my httpd.conf and my web service is running. I have both .pl and .cgi files in the ../cgi-bin folder of the apache web folder. I do not have any other webservers running. When I try to display a page (http://localhost:8888/cgi-bin/test.pl or http://localhost:8888/cgi-bin/webpage.cgi). I get the ie error: "localhost is not set up to establish a connection on port "8888" with this computer." Now, if I try http://localhost/cgi-bin/test.pl I get the error "localhost is not set up to establish a connection on port World Wide Web service (HTTP) with this computer. Can anyone help?
Thanks,
Steve Holdorf

I checked the event logs and have the follow error:
The Apache service named
reported the following error: >>>
httpd.exe: Could not reliably determine the server's fully qualified domain name, using 127.0.0.1 for ServerName
Hope this helps.

Have you solved this yet? are you using it as a development or live server (is it visible to the world or just you?)?

Hi all
Need help on frame breaker code.
i have a page with two frames in it.the pages are built in PHP.
the first page displays page from my site whereas the second frame displays page from the other site for which i do not have control on.
but for some sites that do have a frame breaker code in them, those pages open in the parent window rather than opening in the frame.
have tried the security TAG in Iframe but it works only in IE.
for mozilla its of no use.
tried a few things but to no effect.
tried from this link
http://coderrr.wordpress.com/2009/02/13/preventing-frame-busting-and-click-jacking-ui-redressing/[^]
is it even possibe to do so.
Pls help
Thanks in Advance.

It seems to me, that the way I'd approach it is to do a GET on the desired page, scan the page for any offending code and fix as required.
From the 2minute primer i've just had, it looks like a couple of prime strings to be commented out are "top.location= xxxxxxx" and "top.location.replace"
I guess I'd just try loading the page into a string, and inserting a pair of '/' characters at the start of any line that contains either of the two strings I mentioned. That way, you've killed the javascript before it ever had a chance.

hi enhzflep
thanks for the reply.
can u pls elaborate with the code so that i can understand it.
also if we try to get a page in a string and strip of the Javascript(frame breaker code) then what is the way to display the stripped content in a iframe.
please have a look at the following link
http://www.iframehtml.com/iframe-scripts.html[^]
it tells way to strip the JS from the page but how to display that page in a iframe then
Regards
Sandeep.

That's okay Sandeep. Thank-you for introducing me to the whole concept. It's been rather an interesting exercise.
I've had a little play around, and come up with some code that will kill the framebuster in a page that I've been playing with.
It's a two-file approach. There's the html file that makes the request, and the php file that retrieves the requested file
then strips the offending code from it.
In my simple example, I simply replace "top.location=self.location;" with "alert('Framebuster busted!');"
All you'll have to do is to find, download and compress AjaxRequest.js (EDIT: http://www.ajaxtoolbox.com/request/source.php)
[EDIT: No, you don't. I forgot I used a different method. Anyhow, it's still a good library]
Here's some code to play with:
1. getPage.php
<?php
$url = $_GET["tgt"];
if ($url == "")
die("goddamit");
$ch = curl_init();
curl_setopt($ch, CURLOPT_URL, $url);
curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);
$data = curl_exec($ch);
curl_close($ch);
echo strip_javascript($data, 0);
function strip_javascript($filter, $allowed=0)
{
$filter = str_replace("top.location=self.location;", "alert('Framebuster busted!');", $filter);
return $filter;
}
?>
2. showInIFrame.html

Is there a Python debugger that isn't complete rubbish? I just tried PyScripter and it crashes. I understand Eclipse doesn't have breakpoints which makes no sense to me. I tried WinPdb and the installer crashes.
PS. Looks like Wing IDE works.

I was playing with something the otherday that might be whhat you'r after.
It just displays a (dynamically generated, in this simple example) table, and allows editing by just double-clicking a cell.

I'm not a fan of just writing HTML with javascript e.g. str += '</tr>';
I would rather use the document.createElement( [tag name] ); function. I'm also a huge fan of jQuery.
Below is how I would go about creating a table in Javascript.
<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.1//EN" "http://www.w3.org/TR/xhtml11/DTD/xhtml11.dtd">
<html xmlns="http://www.w3.org/1999/xhtml" xml:lang="en">
<head>
<title>Create Table</title>
<meta http-equiv="Content-Type" content="text/html; charset=utf-8" />
<script type="text/javascript" src="jquery.js"></script>
<script type="text/javascript">
function createTable(rows, columns, newId, parent)
{
$(parent)
.append(
$(document.createElement('table'))
.attr('id' , newId)
);
for (var rowNumber = 1; rowNumber <= rows; rowNumber++)
{
$('#' + newId)
.append(
$(document.createElement('tr'))
.attr('class', (rowNumber % 2 == 0) ? 'even' : 'odd')
);
for (var columnNumber = 1; columnNumber <= columns; columnNumber++)
{
$('#' + newId + ' tr:last-child')
.append(
$(document.createElement('td'))
.html('(' + columnNumber + ', ' + rowNumber + ')')
);
}
}
}
</script>
</head>
<body onload="createTable(10, 10, 'newTable', '#parent');">
<div id="parent"></div>
</body>
</html>

Hi all,
I want to create a PHP IDE.How can i do it ?
Thanks in advance.......

Pick a language - java/c++/C# are probably best, but you could try php & tk (but it's painful). Learn how to build windows and forms with it.
Plan your application on paper n get coding.
I suggest looking at some coding tutorials first. c# and wpf are probably a good starting point.
