• Navigating between activities and tasks

  - by Alex Orlov

  The situation: I have an activity "A" that is a delegator activity, in simple words, it's only purpose is to call activity "B" (via startActivityForResult()) depending on data it receives. Activity "B" has launchMode set to "singleTask", so it always runs in a single task. When activity "A" gets started from another task (for example as a share from gallery) it immediately returns ACTION_CANCELLED for activity "B", finishes, and task of activity "B" comes to front (which is an expected behavior). So, what happens, is that we jump from our Gallery app task, to my activity "B" task. Everything is fine until user presses back. Since we are already in a different task, the back button doesn't lead us back to gallery. It navigates in the stack of activity "B" task. The question: is there any way to navigate from one task, to previously shown task (navigate from activity "B" to gallery)? Or maybe there is a way to take currently running activity "B" and move it to another task?

• Detect EXIF Orientation of an image in javascript

  - by Obi Wan

  In my mobile web application, I have a need to examine the EXIF orientation tag of an image file selected using an input type=file control, and this needs to be done on the client side in javascript, before the selected image file gets uploaded to the server. I have seen several threads similar to this but most of them say to use a library called binaryajax.js to be able to access the EXIF data from the file object. Unfortunately, simply including binaryajax.js in my project causes an Access Denied error in jQuery 1.7.1, and I have no idea why this is happening. This error precludes me from using this jquery library. So I am looking for a solution that does not use this library. Another library I have tried to use is jquery.exif.js and I also get an Access Denied Error Trying to use it.

• Boost Shared Pointer: Simultaneous Read Access Across Multiple Threads

  - by Nikhil

  I have a thread A which allocates memory and assigns it to a shared pointer. Then this thread spawns 3 other threads X, Y and Z and passes a copy of the shared pointer to each. When X, Y and Z go out of scope, the memory is freed. But is there a possibility that 2 threads X, Y go out of scope at the exact same point in time and there is a race condition on reference count so instead of decrementing it by 2, it only gets decremented once. So, now the reference count newer drops to 0, so there is a memory leak. Note that, X, Y and Z are only reading the memory. Not writing or resetting the shared pointer. To cut a long story short, can there be a race condition on the reference count and can that lead to memory leaks?

• jquery scroll to a px count from top and then set a div to be fixed from the top for the rest of the scroll

  - by estern

  I am looking to change a div's css when i scroll to a certain point down the page, a certain amount of pixels from the top of the page. On page load i would have a div positioned statically. Once I started to scroll down the page and i hit a point from the top (say 100px for demo purposes) i want to change that static div to become fixed like 20px from the top. Which would be done via the css() property of jquery. THis would allow it to stay at that fixed 20px all the way down the page. What jquery property can i use to know when i hit that 100px mark. I want this to also revert once someone gets back to the top so that the div is put back to where it was when the page loaded and not 20px from the top. Any ideas?

• What can cause reset connection when running PHP script?

  - by marcin_koss

  I've developed a web application with CodeIgniter that works perfectly on my local machines (one with windows and one with Linux). When I moved it to my hosting server, connection gets reset when running one particular PHP script that does a few MySQL queries and some operations on arrays. The data I'm querying is small, just a few tables with up to 25 records. Firefox returns "The connection was reset" after maybe 2-3 seconds. I checked the servers error logs but there was nothing there. Unfortunately I don't have access to Apache error logs. What can cause this behavior?

• clever way to conditionally split this string?

  - by sprugman

  I've got a string that could be in one of two forms: prefix=key=value (which could have any characters, including '=') or key=value So I need to split it either on the first or second equals sign, based on a boolean that gets set elsewhere. I'm doing this: if ($split_on_second) { $parts = explode('=', $str, 3); $key = $parts[0] . '=' . $parts[1]; $val = $parts[2]; } else { $parts = explode('=', $str, 2); $key = $parts[0]; $val = $parts[1]; } Which should work, but feels inelegant. Got any better ideas in php? (I imagine there's a regex-ninja way to do it, but I'm not a regex-ninja.;-)

• C# Unit Testing: How do I set a Lazy<T>.ValueCreated to false?

  - by michael paul

  Basically, I have a unit test that gets a singleton instance of a class. Some of my tests required me to mock this singleton, so when I do Foo.Instance I get a different type of instance. The problem is that my checks are passing individually, but failing overall because one test is interfering with another. I tried to do a TestCleanup where I set: Foo_Accessor._instance = null; but that didn't work. What I really need is Foo_Accessor._instance.IsValueCreated = false; (_instance is a Lazy). Any way to unset the Lazy object that I didn't think of?

• How to make a service not receive messages at certain times

  - by miker169

  I'm currently learning wcf for an up and coming project. The service I am creating is using MSMQ to update the database, but the database can't accept messages at certain times. The service is going to be a windows service. The one thing I am coming up against at the moment is how I can get the service to stop reading messages from the queue at these times, for instance lets say I don't want to read messages from the queue on sundays. How would I go about implementing this. So that the client can send messages to the queue that update the database but the service doesn't read the messages until monday, so that the database gets all the updates on the monday? I have started looking at creating a customhost, but I'm not sure if I'm heading in the right direction with this. Thanks in advance.

• Application window sent behind other windows on closing different thread (C#)

  - by david.murrant

  I'm writing a Windows Forms Application in C#.NET On startup, the application displays a splash screen which is running in a separate thread. Whilst the splash screen is showing, the main application is initialising. Once the main application has finished initialising, the main form of the application is displayed, and the splash screen still shows over the top. Everything so far is as expected. Then, the Splash screen is closed, which causes that thread to exit. For some reason, at the point, the main application windows gets sent behind all other open Windows, notably the Windows Explorer window where you clicked the .exe file to run the application in the first place! What could be causing the windows to suddenly jump "behind" like this?

• Similar SQL queries returning different results...

  - by Pablo

  Here are the SQL Queries: $sql1 = "SELECT count(thread) AS total FROM comments WHERE thread=1 AND parent_id=0 "; $sql2 = "SELECT count(thread) AS total FROM comments, users WHERE thread=1 AND parent_id=0 AND users.user_id=comments.user_id "; $sql3 = "SELECT comments.*, users.username AS username FROM comments, users WHERE thread=1 AND parent_id=0 AND users.user_id=comments.user_id ORDER BY date LIMIT 10, 5 "; My question is why would $sql1 and $sql2 would return two different results? $sql1 returns 61 rows $sql2 returns 56 rows The 5th line in $sql2 is just for testing, is not required, is just a variation of $sql1 which gets the total rows for a pagination.

• Saving a modified object from ASP.NET MVC View Using Entity-Franework 4

  - by Dani

  I retrieve an object graph from DB using EF4. The context is closed as soon as the data retrieve and the data passes to the controller, and then to the view. in the view the data is modified, and then the controller gets it back. From the controller I run Repository.Update(MyEmp); and in my repository the code goes: using (var context = new mydb()) { if (myEmp.ID != 0) // Checking if it's modified or new { context.Emp.Attach(MyEmp); int result = context.SaveChanges(); return myEmp.ID; } } The problem - once attached, the object entityState goes to unchanged, and not modified, and of course - nothing is saved to the database. What am I doing wrong ?

• How do online stores handle 2 customers that add the last item to their cart?

  - by Alex

  I'm making a store web app for a college class. I'm wondering what do stores like Amazon do when there is only 1 item left? Do they let multiple customers add the last item to their cart, and whoever checks out first gets it? Meaning that the inventory database is updated after purchase. or Do they let only one customer add the last item to their cart and remove the item from the inventory. If the customer's session times out, then the item is put back in the inventory.

• How can I receive percent encoded slashes with Django on App Engine?

  - by J. Frankenstein

  I'm using Django with Google's App Engine. I want to send information to the server with percent encoded slashes. A request like http:/localhost/turtle/waxy%2Fsmooth that would match against a URL like r'^/turtle/(?P<type>([A-Za-z]|%2F)+)$'. The request gets to the server intact, but sometime before it is compared against the regex the %2F is converted into a forward slash. What can I do to stop the %2Fs from being converted into forward slashes? Thanks!

• How to setup custom CSS based on account settings in a Django site?

  - by sdolan

  So I'm writing a Django based website that allows users select a color scheme through an administration interface. I already have middleware/context processors that links the current request (based on domain) to the account. My question is how to dynamically serve the CSS with the account's custom color scheme. I see two options: Add a CSS block to the base template that overrides the styles w/variables passed in through a context processors. Use a custom URL (e.g. "/static/dynamic/css//styles.css") that gets routed to a view that grabs all the necessary values and creates the css file. I'm content with either option, but was wondering if anyone else out there has dealt with similar problems and could give some insight as to "Best Practices".

• Printing contents of a dynamically created iframe from parent window

  - by certainlyakey

  I have a page with a list of links and a div which serves as a placeholder for the pages the links lead to. Everytime user clicks on a link an iframe is created in the div and its src attribute gets the value of the link href attribute - simple and clear, sort of external web pages gallery. What i do have a problem with is printing the contents of the iframe. To do this i use this code: function PrintIframe() { frames["name"].focus(); frames["name"].print(); } The issue seems to be that iframe is created dynamically by JQuery - when I insert an iframe right into the html code, the browser prints the external page all right. But with the same code injected by JavaScript nothing happens. I tried to use JQ 1.3 'live' event on "Print" link, no success. Is there a way to overcome this?

• iOS sdk question: how do I cast a UIView to a UIImage View (alternativly how do I get a UIImageView from a GestureRecognzer?)

  - by user439299

  Desired end result: user taps a UIImageView and the image changes to another image (a subsequent tap returns the image to the original state) Problem: I add a (unique) selector to a bunch of UIImageViews (in an array) and point the action at the same function - let's call this function imageTapped: for now. Here is my code so far: -(void)imageTapped:(UITapGestureRecognizer *)tapGesture { UIImageView *view = tapGesture.view; // rest of code... } This code actually works fine but gets a warning when I run it: "Incompatible objective c types initilizing 'struct UIView *', expected 'struct UIImageView *' Any way to get rid of this? Not sure how casting works in objective c... primitive types seem to work fine such as (int)someFloat works fine but (UIImageView)someUiView doesn't work. Like I said, code works alright when I run it but would like to get ride of the compiler warning. Any help would be awesome.... I am very new to objective c (or any non java language for that matter) so be gentle. Thanks in advance.

• How do you make long SQL invoked from other code readable?

  - by Artem

  This is a very open question, but I think it can be very beneficial for SQL readability. So you have a Java program, and you are trying to call a monster SQL statement from it, with many subqueries and joins. The starting point for my question is a string constant like this: static string MONSTER_STATEMENT = "SELECT " + " fields" + "WHERE "+ " fieldA = (SELECT a FROM TableC) " + "AND fieldB IN (%s)" + "AND fieldC = %d " + "FROM " " tableA INNER JOIN tableB ON ..."; It later gets filled using String.format and executed. What are you tricks for making this kind of stuff readable? Do you separate your inner joins. Do you indent the SQL itself inside the string? Where do you put the comments? Please share all of the tricks in your arsenal.

• Why isn't a JS file hosted on Amazon S3 getting cached by the browser?

  - by Paras Chopra

  I have a JS file hosted on Amazon S3 (http://s3.amazonaws.com/wingify/vis_opt.js). I want the file to be cached on users' browsers so that they don't have to download it with every page view. However, in spite of setting Cache Control header I don't think it is getting cached. Browser still contacts Amazon Server with every pageview. Here is the example of page where this script is embedded: http://myjugaad.in/ If you have Firebug, you will be able to see that browser requests it with every pageview. What can I do so that the file gets permanently cached? Thanks for help.

• Can you get the previous value of a variable in Java?

  - by The Special One

  Say way have a variable (let's say String Str) and the value of Str starts of as " " then as some code is running it is set to "test" then somewhere else in the code it is changed again to say "tester". Now in the program I want to find out what the previous value of Str was. Is this possible in Java? So I am saying that the variable gets changed twice, and you want to find out what Str was before it got changed for the second time. So in the example above the latest value of Str would be "tester" but I wanted to find out what Str was before this (assuming you had no idea what it was before it was changed to tester) in this case I would want to be able to find out that Str was "test". Is it at all possible to do this in Java?

• Scroll immediately to row in table before view shows

  - by cannyboy

  A view with a table gets pushed onto the screen and I want it to scroll to a certain row in the table before the screen actually displays. I use this code within the final viewcontroller. NSIndexPath *scrollToPath = [NSIndexPath indexPathForRow:5 inSection:0]; [theTable scrollToRowAtIndexPath:scrollToPath atScrollPosition:UITableViewScrollPositionTop animated:NO]; When I put it in viewDiDAppear method, then it briefly flashes from the intial position of the table (at the top) to the row I want. I don't want it to show the initial position. If I put it in viewDidLoad or viewWillAppear then it crashes with a NSRangeException, presumably because the table isn't set up yet. How would I get it to scroll without showing the initial position?

• MS SQL Specific Tables Hanging at Queries

  - by Jonn

  I have SQL Server 2008. I run a query in a table on a database. The weirdest thing keeps happening. I run a simple select statement on the table. I know there are 62 rows in the table but it gets stuck at row 48 and goes on "querying...". Waited already for hours and it didn't move on from there. I only know of two programs, and one reporting service connecting to that particular table and one other user. Does anyone have any idea on what could be causing this and how I could trace the source of the lock on that table? As a side note, I noted that the logs only had a notice that Autogrow failed the day before I checked. Could this have something to do with it?

• Getting time from a cell in Google Spreadsheet

  - by lostInTransit

  Hi I have created a Google Spreadsheet form in which for one of the fields I get the time (hh:mm:ss) in 24-hour format. I am using Google Apps Scripts to read values from this spreadsheet and put it into another file. But the other file gets the entire date (don't know from where) and shows a date from 1899. Also the time is shown in PDT (not my time zone). Even the time it prints is not correct How do I read the column value as a string and put it in the other file OR get just the time from the column value (and the correct time) I am using a simple row[0][3] to get the values from an array after doing range.getValues() Thanks.

• Silverlight client load operation failed for query "Login". [GenericParameterNotValid]

  - by cvoeller

  I have one user who gets the following error when trying to login, "Silverlight client load operation failed for query "Login". [GenericParameterNotValid]". The odd thing is that other users are able to login without issue and I can login using the "problem" account from other machines. At this point I think it's got to be a client side configuration issue. My next step is to confirm the Client Side Silverlight Version, but I don't know where to go after that. Do you have any suggestions?
