• Internet Explorer loop bug when preloading images

  - by user335460

  Hi Everyone I have created a JavaScript application that requires all images to be preloaded first. Everything works fine in Firefox but in Internet Explorer my loop skips the count at 19 and goes to 21. Has anyone come across this problem before and what causes it? You can copy and paste the script below for test purposes. var preLoad = function () { var docImages = ["http://www.sanatural.co.za/media/images/map/rsa_prov.gif", "http://www.sanatural.co.za/media/images/map/loading.gif", "http://www.sanatural.co.za/media/images/map/loading2.gif", "http://www.sanatural.co.za/media/images/map/ec_land.gif", "http://www.sanatural.co.za/media/images/map/ec_roll.gif", "http://www.sanatural.co.za/media/images/map/ec_state.gif", "http://www.sanatural.co.za/media/images/map/fs_land.gif", "http://www.sanatural.co.za/media/images/map/fs_roll.gif", "http://www.sanatural.co.za/media/images/map/fs_state.gif", "http://www.sanatural.co.za/media/images/map/gt_land.gif", "http://www.sanatural.co.za/media/images/map/gt_roll.gif", "http://www.sanatural.co.za/media/images/map/gt_state.gif", "http://www.sanatural.co.za/media/images/map/kzn_land.gif", "http://www.sanatural.co.za/media/images/map/kzn_roll.gif", "http://www.sanatural.co.za/media/images/map/kzn_state.gif", "http://www.sanatural.co.za/media/images/map/lp_land.gif", "http://www.sanatural.co.za/media/images/map/lp_roll.gif", "http://www.sanatural.co.za/media/images/map/lp_state.gif", "http://www.sanatural.co.za/media/images/map/mp_land.gif", "http://www.sanatural.co.za/media/images/map/mp_roll.gif", "mp_state.gif", "http://www.sanatural.co.za/media/images/map/nc_land.gif", "http://www.sanatural.co.za/media/images/map/nc_roll.gif", "http://www.sanatural.co.za/media/images/map/nc_state.gif", "http://www.sanatural.co.za/media/images/map/nw_land.gif", "http://www.sanatural.co.za/media/images/map/nw_roll.gif", "http://www.sanatural.co.za/media/images/map/nw_state.gif", "http://www.sanatural.co.za/media/images/map/wc_land.gif", "http://www.sanatural.co.za/media/images/map/wc_roll.gif", "http://www.sanatural.co.za/media/images/map/wc_state.gif"], imageFolder = [], loaded = [], loadedCounter = 0; this.loadImgs = function () { for (var i = 0; i < docImages.length; i++) { imageFolder[i] = new Image(); imageFolder[i].src = docImages[i]; loaded[i] = false; } intervalId = setInterval(loadedCheck, 10); // }; function loadedCheck() { if (loadedCounter == imageFolder.length) { // all images have been preloaded clearInterval(intervalId); alert('All images have been preloaded!'); return; } for (var i = 0; i < imageFolder.length; i++) { if (loaded[i] === false && imageFolder[i].complete) { loaded[i] = true; loadedCounter++; alert(i); // (work fine in FF but i.e goes from 19 to 21 ) } } } }; var preloadObject = new preLoad(); preloadObject.loadImgs();

  Hi I am using prestashop as the cart for my website. I have a problem; the website used to be in dynamic urls. I enabled friendly url writing. The problem is that one page has more than one url. You can access a same page from the dynamic url and static url. In fact a single page has 9 different urls. This obviously creates problems for seo as search engiones penalize my website for this.

• Matching non-[a-zA-Z] characters in PHP regex

  - by Bill X

  I have some strings that need a-strippin': ÃœT: 9.996636,76.294363 Tons of long strings of location codes. A literal regex in PHP won't match them, IE $pattern = /ÃœT:/; echo preg_replace($pattern, "", $row['location']); Won't match/strip anything. (To know it's working, /T:/ does strip the last bit of that string). What's the encoding error going on here? Alternately, I would accept a concise way to take out just the numbers.

• Regular expression for email

  - by Nadeem

  I tried the reg expression ^([a-zA-Z0-9_.-])+@([a-zA-Z0-9_.-])+\.([a-zA-Z])+([a-zA-Z])+ for the email validation. Since I want the user to allow submitting even with the empty email address. So I changed the reg ex to (^([a-zA-Z0-9_.-])+@([a-zA-Z0-9_.-])+\.([a-zA-Z])+([a-zA-Z])+)? But this expression accepts any email address without any validation.

• Spammer relaying via Postfix mail server

  I have a Plesk 9.5 mail server (cm.snowbarre.co.za) on Ubuntu 8.04 LTS which forwards all SMTP traffic to an anti-spam server cacti.snowbarre.co.za.

• Configure IIS site to work with host header & hosts file entry

  - by HarveySaayman

  I'm I bit of an IIS / Web noob (I'm a C# backend service / winforms dev) so please bare with me :-) I've set up a site in IIS on my local dev machine. In the bindings section of the site ive added 4 bindings, all 4 for http: Host Name Port IP Address blog.sourcecube.co.za 26581 * www.blog.sourcecube.co.za 26581 * blog.sourcecube.co.za 26581 127.0.0.1 www.blog.sourcecube.co.za 26581 127.0.0.1 in my hosts file (drivers\etc\hosts), i've added the folling entries: 127.0.0.1 blog.sourcecube.co.za 127.0.0.1 www.blog.sourcecube.co.za when i ping my domain name from the command line it does in fact resolve to the loopback address, 127.0.0.1. So what I'm expecting to happen when i navigate to blog.sourcecube.co.za in my browser is for it to resolve to 127.0.0.1, and when the request hits IIS, it should know which site to serve because of the host header? But when i navigate to blog.sourcecube.co.za, i get an "Unable to connect, Firefox can't establish a connection to the server at blog.sourcecube.co.za" error. What am I doing wrong? --- UPDATE --- Navigating to blog.sourcecube.co.za:26581 from my browser works... I'd like get it working without specifying the port number though.

• Adding "Max Length" to Regex

  - by SeToY

  How can I extend already present Regex's with an attribute telling that the regex can't exceed a maximum length of (let's say) 255? I've got the following regex: ([a-zA-Z0-9_\-\.]+)@((\[[0-9]{1,3}\.[0-9]{1,3}\.[0-9]{1,3}\.)|(([a-zA-Z0-9\-]+\.)+))([a-zA-Z]{2,4}|[0-9]{1,3})(\]?) I've tried it like that, but failed: {.,255([a-zA-Z0-9_\-\.]+)@((\[[0-9]{1,3}\.[0-9]{1,3}\.[0-9]{1,3}\.)|(([a-zA-Z0-9\-]+\.)+))([a-zA-Z]{2,4}|[0-9]{1,3})(\]?)}

• How to validate hostname in perl?

  - by embedded

  Hi, I need to come up with a regular expression to validate hostname against RFC-1123 and RFC-952. Right now I'm using this: ^(?=.{1,255}$)[0-9A-Za-z](?:(?:[0-9A-Za-z]|\b-){0,61}[0-9A-Za-z])?(?:\.[0-9A-Za-z](?:(?:[0-9A-Za-z]|\b-){0,61}[0-9A-Za-z])?)*\.?$/ but this does not do the trick since it does not catch a. as invalid hostname. How do I enhance the reg expression to comply with those RFCs? Thanks

  Hello, I'm no expert in regex but I need to parse some input I have no control over, and make sure I filter away any strings that don't have A-z and/or 0-9. When I run this, Pattern p = Pattern.compile("^[a-zA-Z0-9]*$"); //fixed typo if(!p.matcher(gottenData).matches()) System.out.println(someData); //someData contains gottenData certain spaces + an unknown symbol somehow slip through the filter (gottenData is the red rectangle): In case you're wondering, it DOES also display Text, it's not all like that. For now, I don't mind the [?] as long as it also contains some string along with it. Please help. [EDIT] as far as I can tell from the (very large) input, the [?]'s are either white spaces either nothing at all; maybe there's some sort of encoding issue, also perhaps something to do with #text nodes (input is xml)

• [0-9a-zA-Z]* string expressed with primes or prime-factorization-style way to break it into parts?

  - by HH

  Suppose a string consists of numbers and alphabets. You want to break it into parts, an analogy is primes' factorization, but how can you do similar thing with strings [0-9a-zA-Z]* or even with arbitrary strings? I could express it in alphabets and such things with octal values and then prime-factorize it but then I need to keep track of places where I had the non-numbers things. Is there some simple way to do it? I am looking for simple succinct solutions and don't want too much side-effects. [Update] mvds has the correct idea, to change the base, how would you implement it?

• How do I export a large table into 50 smaller csv files of 100,000 records each

  - by Eddie

  I am trying to export one field from a very large table - containing 5,000,000 records, for example - into a csv list - but not all together, rather, 100,000 records into each .csv file created - without duplication. How can I do this, please? I tried SELECT field_name FROM table_name WHERE certain_conditions_are_met INTO OUTFILE /tmp/name_of_export_file_for_first_100000_records.csv LINES TERMINATED BY '\n' LIMIT 0 , 100000 that gives the first 100000 records, but nothing I do has the other 4,900,000 records exported into 49 other files - and how do I specify the other 49 filenames? for example, I tried the following, but the SQL syntax is wrong: SELECT field_name FROM table_name WHERE certain_conditions_are_met INTO OUTFILE /home/user/Eddie/name_of_export_file_for_first_100000_records.csv LINES TERMINATED BY '\n' LIMIT 0 , 100000 INTO OUTFILE /home/user/Eddie/name_of_export_file_for_second_100000_records.csv LINES TERMINATED BY '\n' LIMIT 100001 , 200000 and that did not create the second file... what am I doing wrong, please, and is there a better way to do this? Should the LIMIT 0 , 100000 be put Before the first INTO OUTFILE statement, and then repeat the entire command from SELECT for the second 100,000 records, etc? Thanks for any help. Eddie

• problems with url and email regex when searching text

  - by Grant Collins

  Hi, I'm having problems with regular expressions that I got from regexlib. I am trying to do a preg_replace() on a some text and want to replace/remove email addresses and URLs (http/https/ftp). The code that I am have is: $sanitiseRegex = array( 'email' => /'^([a-zA-Z0-9_\-\.]+)@((\[[0-9]{1,3}\.[0-9]{1,3}\.[0-9]{1,3}\.)|(([a-zA-Z0-9\-]+\.)+))([a-zA-Z]{2,4}|[0-9]{1,3})(\]?)$/', 'http' => '/^(http|https|ftp)\://[a-zA-Z0-9\-\.]+\.[a-zA-Z]{2,3}(:[a-zA-Z0-9]*)?/?([a-zA-Z0-9\-\._\?\,\'/\\\+&amp;%\$#\=~])*$/', ); $replace = array( 'xxxxx', 'xxxxx' ); $sanitisedText = preg_replace($sanitiseRegex, $replace, $text); However I am getting the following error: Unknown modifier '/' and $sanitisedText is null. Can anyone see the problem with what I am doing or why the regex is failing? Thanks

• Having trouble searching for a ‘.’ using htaccess.

  - by ThisLanham

  I'm setting up a website that (ideally) would allow users to access other users' homepages with a url in the format "www.mysite.com/ThisLanham" where 'ThisLanham' is the username. The username begins with a letter and can consists of any alphanumeric character along with an underscore, hyphen, or period. So far, the redirection has worked perfectly when I ignore usage of the period character. The following code handles that request: RewriteRule ^([a-zA-Z][0-9a-zA-Z-_]*)/?$ Page/?un=$1 [NC,L] However, I've tried a number of ways it check for the period as well, but all have resulted in a 500 Internal Server Error. Here are some my attempts: RewriteRule ^([a-zA-Z][0-9a-zA-Z-\_\\.]\*)/?$ Page/?un=$1 [NC,L] RewriteRule ^([0-9a-zA-Z-\_\\.]\*)/?$ Page/?un=$1 [NC,L] RewriteRule ^([a-zA-Z].\*)/?$ Page/?un=$1 [NC,L] RewriteRule ^(.\*)/?$ Page/?un=$1 [NC,L] also tried... RewriteCond $1 != index.php RewriteRule ^([a-z][0-9a-z-_.]*)/?$ Page/?un=$1 [NC,L] My backup plan is to no longer allow users to include periods in their usernames, but I'd much rather find a solution. Any ideas?

• User Permissions: Daemon and User

  - by Eddie Parker

  Hello: I often run into this issue on Linux, and I'd love to know the proper way of solving it. Say I have a daemon running. In my example, I'll use LigHTTPD, a webserver. Some software, like Wordpress, enjoys having read/write access to files for updating applications via a web interface, which I think is quite handy. At the same time, I enjoy being able to hack on my files using vim, using my local user account, 'eddie'. Herein lies the rub. Either I chown everything to lighttpd or eddie and a shared group between them both, and chmod it 660, or perpetually sudo to edit the damned things. The former isn't a bad solution, until I create a new file in which case I have to remember to chmod it appropriately, or create some hack like a cron job that chmods for me. Is there an easier way of doing this? Have I overlooked something? Cheers, -e-

• Regex for [a-zA-Z0-9\-] with dashes allowed in between but not at the start or end

  - by orokusaki

  I'm using Python and I'm not trying to extract the value, but rather test to make sure it fits the pattern. allowed values: spam123-spam-eggs-eggs1 spam123-eggs123 spam 123 eggs123 I just can't have a dash at the starting or the end. There is a question on here that works in the opposite direction by getting the string value after the fact, but I simply need to test for the value so that I can disallow it. Also, it can be a maximum of 25 chars long, but a minimum of 4 chars long. Here's what I've come up with after some experimentation with lookbehind, etc: # Nothing here
