  • I would like to know how to put a "change image" layer like in facebook on a mouseover event

    - by netadictos
    Hello: I have a photo gallery I would like that every time a user does mouseover the image, there is a button on the top of this image that appears. The user can click on it. But every time that the user mouse out of the photo it must disappear. It works like the "change photo" in Facebook, with the photo of your profile. The problem I am having is that when I try to get over the button that appears (in my code is a link), it disappear because javascript understands that the mouse is just out of the image, even if this button/link is over the image. The image that I use is positioned absolutely over the image. This is my code, where you can see that I create a dom element that I append on the link of the image and then when there is a mouseout, I remove it. $('a.ftelement').mouseover(function() { var fav = $('<a></a>'); fav.attr("class","imgfavorito"); fav.attr("id","fav"+$J(this).attr("id")).html("<img src=\"/im/favorito.gif\"/>"); fav.appendTo(this); }); $('a.ftelement').mouseout(function() { $("a.imgfavorito").remove() }); The result is this graphically (http://www.freeimagehosting.net/uploads/41fbac8994.gif):

  • Displaying Photos on iPhone

    - by Bjorn S.
    Hi all, I'm working on an iPhone app and I need to be able to display images to users. I have already gotten the code that takes the photo and stores it into the filesystem working well. Now I just need to figure out how to display the image. I've looked at the Three20 project I've read about on a few of the posts here, but it seems a bit cumbersome and like an extra dependency to import link and combine all of the Three20 library into my little app. Are there any other ways or a more streamlined library that will let me display photos to my users? Thanks! B.

  • Collision detection on sub views contained in 2 separate parent UIViews?

    - by Chris
    Hi All, I originally setup some conditions using CGRectIntersectsRect for some collision detection which worked fine. In the greater scale of things I only need part of the view to be detected. So originally within the ViewController it was comparing 2 UIviews. Now what I need to do is collision detection of subViews within 2 different UIViews that are contained in a view in which the view controller does the logic. My script is no longer working as I suspect CGRectIntersectsRect only compares frames within the same view? I'll keep digging to confirm this. Any ways around this? Is it possible for example to get the x and y pos of the sub view in relation to the main view that's performing the logic?

    I am using Jquery's Just Another Carousel plugin and I'm having issues with something which I am not sure and because of this it's not working. I'm using this plugin because I need fixed height rather than fixed width. This Doesn't Works (When used Refresh CTRL+F5) any help?

  • Regular Expression Newbie

    - by Registered User
    I need to parse strings inputs where the columns are separated by columns and any field that contains a comma in the data is wrapped in quotes (commas separated, quoted text identifiers). For this project I need to remove the quotes and any commas that occur between pairs of quotes. Basically, I need to remove commas and quotes that are contained in fields while preserving the commas that are used to separate the fields. Here's a little code I put together that handles the simple scenario: // Sample input 1: This works and covers 99% of the records that I need to parse. string str1 = "[email protected],2010/03/27 12:2:02,,some_first_name,some_last_name,,\"This Address Works, Suite 200\",Some City,TN,09876-5432,9795551212x123,XYZ"; str1 = Regex.Replace(str1, "\"([^\"^,]*),([^\"^,]*)\"", "$1$2"); Console.WriteLine(str1); // Outputs: [email protected],2010/03/27 12:2:02,,some_first_name,some_last_name,,This Address Works Suite 200,Some City,TN,09876-5432,9795551212x123,XYZ Although this code works for most of my records, it doesn't work when a field contains more than one commas. What I would like to do is modify the code so that it remove each instance of a comma contained within the column no matter how many commas there are in the field. I don't want to hard code only handling 2 commas, or 3 commas, or 25 commas. The code should just remove all the commas in the field. Below is an example of what my code doesn't handle properly. // Sample input 2: This doesn't work since there is more than 1 comma between the quotes. string str2 = "[email protected],2010/03/27 12:2:02,,some_first_name,some_last_name,,\"i,l,k,e, c,o,m,m,a,s, i,n ,m,y, f,i,e,l,d\",Some City,TN,09876-5432,9795551212x123,XYZ"; str2 = Regex.Replace(str2, "\"([^\"^,]*),([^\"^,]*)\"", "$1$2"); Console.WriteLine(str2); // Desired output: [email protected],2010/03/27 12:2:02,,some_first_name,some_last_name,,i like commas in my field,Some City,TN,09876-5432,9795551212x123,XYZ Any help would be appreciated for this Regular Expression newbie.

  • Python unit-testing with nose: Making sequential tests

    - by cool-RR
    I am just learning how to do unit-testing. I'm on Python / nose / Wing IDE. (The project that I'm writing tests for is a simulations framework, and among other things it lets you run simulations both synchronously and asynchronously, and the results of the simulation should be the same in both.) The thing is, I want some of my tests to use simulation results that were created in other tests. For example, synchronous_test calculates a certain simulation in synchronous mode, but then I want to calculate it in asynchronous mode, and check that the results came out the same. How do I structure this? Do I put them all in one test function, or make a separate asynchronous_test? Do I pass these objects from one test function to another? Also, keep in mind that all these tests will run through a test generator, so I can do the tests for each of the simulation packages included with my program.

  • Objective-C library recommendation for AES-256 in CTR mode

    - by lpfavreau
    Hello, I'm looking for recommendations on an Objective-C library for AES-256 encryption in CTR mode. I have a database full of data encrypted with another library using CTR and seems the included CCCrypt only supports ECB or CBC with PKCS#7. Any idea on the best portable library I should use? I'm not looking to port the original implementation as I don't have the required knowledge in cryptography and hence, that's-a-bad-idea (tm). Thanks!

  • Why doesn't VB.NET 9 have Automatic Properties like C# 3??

    - by Chris Pietschmann
    Would having a nice little feature that makes it quicker to write code like Automatic Properties fit very nicely with the mantra of VB.NET? Something like this would work perfect: Public Property FirstName() As String Get Set End Property UPDATE: VB.NET 10 (coming with Visual Studio 2010 and .NET 4.0) will have Automatic Properties. Here's a link that shows a little info about the feature: http://geekswithblogs.net/DarrenFieldhouse/archive/2008/12/01/new-features-in-vb.net-10-.net-4.0.aspx In VB.NET 10 Automatic Properties will be defines like this: Public Property CustomerID As Integer

  • issue with std::advance on std::sets

    - by tim
    I've stumbled upon what I believe is a bug in the stl algorithm advance. When I'm advancing the iterator off of the end of the container, I get inconsistent results. Sometimes I get container.end(), sometimes I get the last element. I've illustrated this with the following code: #include <algorithm> #include <cstdio> #include <set> using namespace std; typedef set<int> tMap; int main(int argc, char** argv) { tMap::iterator i; tMap the_map; for (int i=0; i<10; i++) the_map.insert(i); #if EXPERIMENT==1 i = the_map.begin(); #elif EXPERIMENT==2 i = the_map.find(4); #elif EXPERIMENT==3 i = the_map.find(5); #elif EXPERIMENT==4 i = the_map.find(6); #elif EXPERIMENT==5 i = the_map.find(9); #elif EXPERIMENT==6 i = the_map.find(2000); #else i = the_map.end(); #endif advance(i, 100); if (i == the_map.end()) printf("the end\n"); else printf("wuh? %d\n", *i); return 0; } Which I get the following unexpected (according to me) behavior in experiment 3 and 5 where I get the last element instead of the_map.end().

What am I missing? Thanks!

  • Draw window with just borders

    - by Tonatiuh
    How can I create a application window that is showing just the borders of the window, but i don't want to show the contents of the window itself. I mean i want to see the rest of the desktop or the others windows through the entire region of my window. No using transparences. Just draw the borders. I suppose it's like detecting the messages WM_ERASEBKGND and WM_PAINT and doing nothing in these cases to force not painting in the contens, but I have tried and window is still drawing a white background. How can i get it?

  • Python regex group clarification

    - by nkr1pt
    I have 0 experience with python, very little with regex and I'm trying to figure out what this small snippet of python regex would give back from a http response header Set-Cookie entry: REGEX_COOKIE = '([A-Z]+=[^;]+;)' resp = urllib2.urlopen(req) re.search(REGEX_COOKIE, resp.info()['Set-Cookie']).group(1) Can one give a simple example of a Set-Cookie value and explain what this would match on + return?

  • Is it possible to make the iPhone keyboard invisible / remove it without resigning first responder?

    - by Alex Gosselin
    I am looking for a way to show my own input view (a UITableView) to enter certain keywords in a UITextView faster than typing them, and also be able to type into this text view the normal way. My solution has a button that causes the keyboard to disappear, revealing the table view underneath it. Problem is I can't figure out how to make the keyboard go away without resigning first responder, and losing the cursor. Has anyone accomplished this before? Thanks for any help.

  • Save object in CoreData

    - by John
    I am using CoreData with iPhone SDK. I am making a notes app. I have a table with note objects displayed from my model. When a button is pressed I want to save the text in the textview to the object being edited. How do I do this? I've been trying several things but none seem to work. Thanks EDIT: NSManagedObjectContext *context = [fetchedResultsController managedObjectContext]; NSEntityDescription *entity = [[fetchedResultsController fetchRequest] entity]; NSManagedObject *newManagedObject = [NSEntityDescription insertNewObjectForEntityForName:[entity name] inManagedObjectContext:context]; [newManagedObject setValue:detailViewController.textView.text forKey:@"noteText"]; NSError *error; if (![context save:&error]) { /* Replace this implementation with code to handle the error appropriately. abort() causes the application to generate a crash log and terminate. You should not use this function in a shipping application, although it may be useful during development. If it is not possible to recover from the error, display an alert panel that instructs the user to quit the application by pressing the Home button. */ NSLog(@"Unresolved error %@, %@", error, [error userInfo]); abort(); } The above code saves it correctly but it saves it as a new object. I want it to be saved as the one I have selected in my tableView.

  • How to keep historic details of modification in a database (Audit trail)?

    - by mada
    I'm a J2EE developer & we are using hibernate mapping with a PostgreSQL database. We have to keep track of any changes occurs in the database, in others words all previous & current values of any field should be saved. Each field can be any type (bytea, int, char...) With a simple table it is easy but we a graph of objects things are more difficult. So we have, speaking in a UML point of view, a graph of objects to store in the database with every changes & the user. Any idea or pattern how to do that?

  • Magento: Getting Product Url's for Products within a Grouped Product

    - by Nathan
    For a grouped product, I would like to display a link to the simple products it is composed of. For example, if I have a grouped product called Dining Set composed of plates, knives, forks, etc. I'd like each of the subproducts to have a link to that subproduct (click plates goes to the Simple Product for plates) <?php foreach ($_associatedProducts as $_item): ?> <tr> <td><?php echo $this->htmlEscape($_item->getName()) ?></td> <td class="a-right"> <?php echo $this->getPriceHtml($_item, true) ?> </td> <?php if ($_product->isSaleable()): ?> <td class="a-center"> <?php if ($_item->isSaleable()) : ?> <a href="<?php $_item->getProductUrl() ?>">View</a> <?php else: ?> <p class="availability"><span class="out-of-stock"><?php echo $this->__('Out of stock.') ?></span></p> <?php endif; ?> </td> <?php endif; ?> </tr> <?php endforeach; ?> This is a code snippet from the grouped.phtml file in app/design/frontend/blank/default/template/catalog/product/view/type/grouped.phtml In particular the line that has $_item-getProductUrl() This does not work, and I don't know the code needed to get the url for this associated product item. If anyone could help here it would be much appreciated. Also, where on earth can I find the method's available (and how they're used) for Products or Categories or $_item and the like? Thanks, Nathan
