    - by Muhammad
    I am using Jquery plot.Every thing is working except tooltip data. Total data shown on a line is 190 which is equal to total published PLUS total unpublished.Total Published is 51 which is shown in tooltip.Now the other portion of tooltip shows 190 instead of 190-51 = 139 here is my code var options1 = { series: {stack: stack, lines: { show: lines, fill: false, steps: steps }, bars: { show: bars, barWidth: 0.4 }, points: { show: true} }, grid: { hoverable: true //IMPORTANT! this is needed for tooltip to work }, tooltip: true, tooltipOpts: { content: "%s : %y", shifts: { x: -60, y: 25 } }, legend:{'position':'ne','show':true,'margin':[-3, -20],'backgroundOpacity':0.1, 'noColumns': 4, 'container': null}, xaxis: {ticks: dest4 ,}, }; what i should do with this line to show exact data content: "%s : %y",

  • Advice on Method overloads.

    - by Muhammad Kashif Nadeem
    Please see following methods. public static ProductsCollection GetDummyData(int? customerId, int? supplierId) { try { if (customerId != null && customerId > 0) { Filter.Add(Customres.CustomerId == customerId); } if (supplierId != null && supplierId > 0) { Filter.Add(Suppliers.SupplierId == supplierId); } ProductsCollection products = new ProductsCollection(); products.FetchData(Filter); return products; } catch { throw; } } public static ProductsCollection GetDummyData(int? customerId) { return ProductsCollection GetDummyData(customerId, (int?)null); } public static ProductsCollection GetDummyData() { return ProductsCollection GetDummyData((int?)null); } 1- Please advice how can I make overloads for both CustomerId and SupplierId because only one overload can be created with GetDummyData(int? ). Should I add another argument to mention that first argument is CustomerId or SupplierId for example GetDummyData(int?, string). OR should I use enum as 2nd argument and mention that first argument is CustoemId or SupplierId. 2- Is this condition is correct or just checking 0 is sufficient - if (customerId != null && customerId 0) 3- Using Try/catch like this is correct? 4- Passing (int?)null is correct or any other better approach. Edit: I have found some other posts like this and because I have no knowledge of Generics that is why I am facing this problem. Am I right? Following is the post. http://stackoverflow.com/questions/422625/overloaded-method-calling-overloaded-method

  • PHP Export to CSV

    - by Ali Hamra
    I'm not really familiar with PHP exporting to excel or csv, but I'm using PHP MySQL for a local point of sale. According to the code below, this actually works..But not in the way it should be ! All records are placed as 1 row inside the csv file, how can i fix that ? Also, How would I stop overwriting the same file...I mean When I click on a Button to export the csv, it should check if there is an existing csv file, If there is--Create new one ! Thank You require_once('connect_db.php'); $items_array = array(); $result = mysql_query("SELECT * FROM sold_items"); while($row = mysql_fetch_array($result)) { $items_array[] = $row['item_no']; $items_array[] = $row['qty']; } $f = fopen('C:/mycsv.csv', 'w'); fputcsv($f, $items_array); fclose($f);

  • Suppressing a function's command window output in Matlab

    - by Ali
    A function I'm using has "display()" in it (or other things that display messages on command window), so it outputs a lot of things (x 1200) on command line when I run my code, which makes things hard to track and observe. Is there a way to suppress the output of this specific function? Ending the statement with semicolon obviously doesn't help.

  • one page has 9 urls. I am looking for 301 auto redirect syntax for multiple urls.

    - by Ali Demirtas
    Hi This is the third time I am asking this question. I am only looking for the syntax of how to solve this problem. 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 engines penalize my website for this. Here are examples of a page with more than 2 urls (http://www.turkishfootballstore.com/lang-nl/product.php?id_product=515) (http://www.turkishfootballstore.com/fenerbahce/515-fenerbahce-thuisshirt-20092010.html) (http://www.turkishfootballstore.com/lang-nl/fenerbahce/515-fenerbahce-thuisshirt-20092010.html) you can see even the static url's have 2 one with language defined and the other without. out fo the three urls above the correct one is the one at the bottom. What can I do to solve this problem? I have no knowledge of programming. Here is the htaccess for the website. Any sample code or help is really appreciated. There is 550 pages and every page is published in 17 different languages I want to use a 301 auto redirect. What is the simplest way to do it? Please only reply if you have the coding for a auto 301 redirect!

  • Backup AWS Dynamodb to S3

    - by Ali
    It has been suggested on Amazon docs http://aws.amazon.com/dynamodb/ among other places, that you can backup your dynamodb tables using Elastic Map Reduce, I have a general understanding of how this could work but I couldn't find any guides or tutorials on this, So my question is how can I automate dynamodb backups (using EMR)? So far, I think I need to create a "streaming" job with a map function that reads the data from dynamodb and a reduce that writes it to S3 and I believe these could be written in Python (or java or a few other languages). Any comments, clarifications, code samples, corrections are appreciated.

  • The best way to assign an immutable instance to a Collection in Java

    - by Ali
    Today I was reading through some Hibernate code and I encounter something interesting. There is a class called CollectionHelper that defines the following constant varibale: public final class CollectionHelper { public static final List EMPTY_LIST = Collections.unmodifiableList( new ArrayList(0 ) ; public static final Collection EMPTY_COLLECTION = Collections.unmodifiableCollection(new ArrayList(0) ); public static final Map EMPTY_MAP = Collections.unmodifiableMap( new HashMap(0) ); They have used these constants to initialize collections with immutable instances. Why they didn't simply use the Collections.EMPTY_LIST for initializing lists? Is there a benefit in using the following method?

  • const object and const constructor

    Is there any way to know if an object is a const object or regular object, for instance consider the following class class String { String(const char* str); }; if user create a const object from String then there is no reason to copy the passed native string and that because he will not make any manipulation on it, the only thing he will do is get string size, string search and other functions that will not change the string.

  • Automatic logout in python web app

    - by Ali
    I have a web application in python wherein the user submits their email and password. These values are compared to values stored in a mysql database. If successful, the script generates a session id, stores it next to the email in the database and sets a cookie with the session id, with allows the user to interact with other parts of the sight. When the user clicks logout, the script erases the session id from the database and deletes the cookie. The cookie expires after 5 hours. My concern is that if the user doesnt log out, and the cookie expires, the script will force him to login, but if he has copied the session id from before, it can still be validated. How do i automatically delete the session id from the mysql database after 5 hours?

  • Can't get message body of certain emails from inbox using the Zend framework?

    - by Ali
    Hi guys I'm trying to read through an email inbox for my application - I'm using the zend framework here. The problem is that I'm unable to retrieve the message body for certain emails. The following is my code as to how I'm doing this: $mail = new Zend_Mail_Storage_Imap($mail_options); $all_messages = array(); $page = isset($_GET['page'])?$_GET['page']:1; $limit = isset($_GET['limit'])?$_GET['limit']:20; $offset = (($page-1)*$limit)+1; $end = ($page*$limit)>$c?$c:($page*$limit); for ($i=$offset;$i<=$end;$i++){ $h2t = new html2text(); $h2t->set_allowed_tags('<a>'); if(!$mail[$i]) break; else{ $one_message = $mail->getMessage($i); $one_message->id = $i; $one_message->UID = $mail->getUniqueId($i); $one_message->parts = array(); $one_message->body = ''; $count = 1; foreach (new RecursiveIteratorIterator($mail->getMessage($i)) as $ii=>$part) { try { $tpart = $part; //$tpart->_content = ''; $one_message->parts[$count] = $tpart; $count++; // check for html body if (strtok($part->contentType, ';') == 'text/html') { $b = $part->getContent(); if($part->contentTransferEncoding == 'quoted-printable') $b = quoted_printable_decode($b); $one_message->html_body = $b; $h2t->set_html($b); $one_message->body = $h2t->get_text(); } //check for text body if (strtok($part->contentType, ';') == 'text/plain') { $b = $part->getContent(); if($part->contentTransferEncoding == 'quoted-printable') $b = quoted_printable_decode($b); $one_message->text_body = $b; $one_message->body = $b;//$part->getContent(); } } catch (Zend_Mail_Exception $e) { // ignore } } $all_messages[] = $one_message; } } The problem is that randomly some messages don't return even a textbody or an html body. Even though if I check using a webvmail client those emails have a message body as well. WHat am I missing here?
