  • Can I pass a pointer to a superclass, but create a copy of the child?

    - by Alex
    I have a function that takes a pointer to a superclass and performs operations on it. However, at some point, the function must make a deep copy of the inputted object. Is there any way I can perform such a copy? It occurred to me to make the function a template function and simply have the user pass the type, but I hold out hope that C++ offers a more elegant solution.

  • Animate absolutely positioned div, but stop if a condition is true?

    - by Alex
    Hello all, I have a div which I place at the top right-hand corner of a website, absolutely positioned at top: 0px and right : 0px. I want to use jquery's animate function to animate the div left or right a certain amount when a button is clicked, but stop the animation if at anytime, the div's offset to the left or right is less than a certain number. I want to do this to accomodate users who click the left or right buttons more than once, so that the div does not fly out of sight. How does one accomplish this? Below is my relevant css, html, and jquery code: CSS: #scorecardTwo { position:absolute; padding:5px; width: 300px; background-color:#E1E1E1; right:0px; top:0px; display:none; } HTML: <div id = "scorecardTwo"> <span id = "dealHolder"><a href="some/link">some text</a></span> <br /> <span id = "scoreHolder">some text</span> <br /> <button type="button" id="moveLeft">Left</button>&nbsp;<button type="button" id="moveRight">Right</button> </div> jQuery (at the moment): $("#scorecardTwo").fadeIn("slow"); $("#moveLeft").bind("click", function() { $("#scorecardTwo").animate({"right":"+=76%"}, "slow"); // how to stop animation if offset is less than appropriate number? }); $("#moveRight").bind("click", function() { $("#scorecardTwo").animate({"right" : "-=76%"}, "slow"); // how to stop animation if offset is less than appropriate number? });

  • Need help with cURL and POSTing in PHP

    - by alex
    I need to post to a payment gateway. The example PHP script for the gateway simply sets the XML like this curl_setopt($ch, CURLOPT_POSTFIELDS, $xmlRequest); // $xmlRequest is just a string of XML In all of my experience, generally you need to use an array with key/values or a string similar to GET params. I am using Kohana, and tracked down a cURL module. It accepts the POST key/values as an array only. Now, I could ditch the module and throw some cURL straight in, but I am using this module fine all throughout the site, so would prefer to use it here. So, my question is, how does that first one work? Does it just POST the whole thing without any named key? Is there a default key I could use for an array to get the module to work?

  • SVN - ignoring files already in repository

    - by Alex
    I have a configuration file in my project which needs to be in the repository (so new developers get it when they checkout the project). Each developer might change some values in the file locally - these changes should not be committed and I don't want them showing in the synchronization menu (I'm using eclipse and subversive if it matters). Note that I can't just set the svn:ignore property since it only works on files that aren't under version control - but I do want to keep a base version of the file in the repository. How can I avoid the file showing in synchronization without deleting it from repository? EDIT: A better description - what I actually need is to be able to set a "read-only" property on the config file, so it can't be changed in the repository as long as the property is on. Do you know anything like this? Thanks

  • ThickBox - update inside without redirect

    - by Alex Maslakov
    ASP.NET MVC and jQuery ThickBox. I show some content in ThickBox. It includes file upload form The view multi-media.apsx (it's strange, the this editor doesn't allow start the line with "<" in the code) form action="/upload/multi-media" method="post" enctype="multipart/form-data" label for="file"File name: input type="file" name="file" id="file" / input type="submit" value="Upload" / <% if (Model.Count > 0) { foreach (FileInfo mediaFile in Model) { <img width="100px" height="100px" src="<%: ResolveUrl("~/audio.png") %>" border="0" alt="<%: mediaFile.Name %>" / //................ After file upload I redirect to /upload/multi-media action and content shows in normal window, not in ThickBox. [ActionName("multi-media"), HttpPost] public ActionResult MultiMedia(HttpPostedFileBase file) { if (file.ContentLength > 0) { file.SaveAs(GenerateNewFileName(fullFileName)); return View("multi-media", model); } } How can I stay into ThickBox after file upload? I need show content in ThickBox all the time, even after the file upload.

  • Shorter GUIDs than hashing a user id?

    - by Alex Mcp
    I'm wondering how Instapaper (bookmarklet that saves text) might generate URLs for their bookmarklet. Mine has a script src of something similar to www.instapaper.com/j/AnJHrfoDTRia The quality of these URLs is that they need to never collide, and not be really guessable (so other people can't save to your account). I know a simple approach might be to MD5 their email address (presumed to have been checked on signup for uniqueness), but then I'd end up with a super long string. This isn't a huge issue, but I'm wondering what techniques there are for shorter GUIDs that won't collide too often (this is obviously the tradeoff, but 12 characters above is pretty short in my opinion)

  • Why does only one of these @-webkit-keyframes declarations fail?

    - by Alex Ford
    I have two -webkit-keyframes declarations (see below). blink2 works fine. blink does nothing. What's the deal? Is there a limit to the number of keyframes that can be declared? @-webkit-keyframes blink { 0% { opacity:1; } 40% { opacity:1; } 50% { opacity:.5; } 90% { opacity:1; } 99% { opacity:1; } } @-webkit-keyframes blink2 { 0% { opacity:1; } 50% { opacity:.25; } 100% { opacity:1; } }

  • Replace a DIV with another using effect and set cookie

    - by Alex
    Hi. I've got some complicated requirements and wondered if there's a way to accomplish this via jQuery: User comes to a web page for the first time today and we show DIV_1. After 30 seconds, we dissolve DIV_1 to DIV_2. We set a cookie on the user's machine that expires when s/he returns tomorrow. If the same user returns today, we only show DIV_2. Tomorrow, we repeat the process: The user will see DIV_1 and then it dissolves to DIV_2. How do you accomplish this via jQuery? Thank you.

  • How to get a category listing from Magento?

    - by alex
    I want to create a page in Magento that shows a visual representation of the categories.. example CATEGORY product 1 product 2 ANOTHER CATEGORY product 3 My problem is, their database is organised very differently to what I've seen in the past. They have tables dedicated to data types like varchar, int, etc. I assume this is for performance or similiar. I haven't found a way to use MySQL to query the database and get a list of categories. I'd then like to match these categories to products, to get a listing of products for each category. Unfortunately Magento seems to make this very difficult. Also I have not found a method that will work from within a page block.. I have created showcase.phtml and put it in the XML layout and it displays and runs it's PHP code. I was hoping for something easy like looping through $this-getAllCategories(); and then a nested loop inside with something like $category-getChildProducts(); Can anyone help me? Thank you!

  • What is the correct HTTP status code to send when a site is down for maintenance?

    - by alex
    Is there a HTTP status code to tell Google (and others) to go away, index me again later? Basically, one that semantically tells clients that the site is down for maintenance? The ones I have considered are 304 => Not modified 307 => Temporary redirect 410 => Gone 503 => Service Unavailable I'm leaning towards the last one, but was just curious as to which one was proper choice. Thanks Update Is this the correct way to send it with PHP? header('Status: 503 Service Unavailable');

  • Save or update for FK relationship Sqlalchemy

    - by Alex
    I've googled, but haven't been able to find the answer to this seemingly simple question. I have two relations, a customer and an order. Each order is associated to a single cusomter, and therefore has a FK relationship to the customer table. The customer relation only stores customer names, and I have set a unique constraint on the customer table barring duplicate names. Let's say I create a new order instance and set a customer for the order. Something like: order_instance.customer = Customer("customer name") When I save the order instance, SqlAlchemy will complain if a customer with this name already exists in the customer table. How do I specify to SqlAlchemy to insert into the customer table if a customer with this name doesn't already exist, or just ignore (or even update) to the customer relation? I don't really want to have to check each time if a customer with some name already exists...

  • How do I delete in Django? (mysql transactions)

    - by alex
    If you are familiar with Django, you know that they have a Authentication system with User model. Of course, I have many other tables that have a Foreign Key to this User model. If I want to delete this user, how do I architect a script (or through mysql itself) to delete every table that is related to this user? My only worry is that I can do this manually...but if I add a table , but I forget to add that table to my DELETE operation...then I have a row that links to a deleted, non-existing User.

  • Bind an event handler to multiple elements jQuery?

    - by Alex
    Hello all. I've done some experimenting, but can't seem to successfully bind one event handler to multiple elements using jQuery. Here's what I've tried: $('selector1', 'selector2').bind('click', function() { $('someSelector').removeClass('coolClass'); }); I've tested all my selectors, and they are all valid. Is what I'm trying to do even possible? If so, can I do it with .live() as well? Thanks!
