• Share data between local service and the hosting activity

  - by Moshik

  Hi, i need to share data between a local service and his hosting activity, i`am using sendBroadcast in order to send data to the hosting activity from the service, but if i want to send data back to the service from the hosting activity? so i though to create static method on the service, and call from the activity, and through it send the parameter, but then i cant do operations like toast inside that static method(which is inside the service).. coz you cant use "myclass.this" inside a static method, i guess there r more limits.. mybe another solution? mybe there is a proper way for this task? thanks, moshik.

• Purely functional equivalent of weakhashmap?

  - by Jon Harrop

  Weak hash tables like Java's weak hash map use weak references to track the collection of unreachable keys by the garbage collector and remove bindings with that key from the collection. Weak hash tables are typically used to implement indirections from one vertex or edge in a graph to another because they allow the garbage collector to collect unreachable portions of the graph. Is there a purely functional equivalent of this data structure? If not, how might one be created? This seems like an interesting challenge. The internal implementation cannot be pure because it must collect (i.e. mutate) the data structure in order to remove unreachable parts but I believe it could present a pure interface to the user, who could never observe the impurities because they only affect portions of the data structure that the user can, by definition, no longer reach.

• POST request is returning response success but is not posting the data

  - by Vineeth

  I am making a POST request to the MOXTRA API and it should return me the following response : { "data": { "id": user_id, //some user id "revision": 5, "name": "My First Binder", "created_time": 1402384947587, "updated_time": 1402384947587 }, "code": "RESPONSE_SUCCESS" } And I am making this POST request using Java Script var d = { 'name': 'My First Binder' }; var bind = JSON.stringify(d); $.post('https://api.moxtra.com/user_id/binders?access_token=' + access_token+ '&callback=?', bind, function(response) { alert( response.data.id); },'json'); }) But the alert that i get for alert(response.data.id) is "undefined" and the alert if i write alert(response.code) is "RESPONSE_SUCCESS" What is wrong with the above code , how am i getting a response success and getting undefined at the same time

• AJAX with jQuery not returning data

  - by James P

  This is my Javascript: $(document).ready(function() { $('#like').bind('keydown', function(e) { if(e.keyCode == 13) { var likeMsg = $('#like').val(); if(likeMsg) { // Send the AJAX request to like.php $.ajax({ url: 'like.php', success: function(data) { alert('Content: ' + data); } }); } } }); }); And this is my like.php file: <?php echo "It works! :)"; ?> When I press enter on the #like input, it seems the AJAX request is sent and an alert box comes up saying: Content:, but there's no data being sent back from like.php... I have checked if the file exists and if it's in the same directory and whatever and it is, so I'm pretty much clueless atm. Does anyone know what could be wrong here? Cheers.

• Embedded Java Databases for Large Data Sets

  - by ExAmerican

  I would like to port a PHP/MySQL-based client/server application to be a standalone desktop application written in Java. The database has grown to be fairly large, with several tables with hundreds of thousands of rows. I expect these could grow to over a million entries for certain tables. What embedded database would best handle this? HSQLDB and Sqlite seem to be the obvious choices, though I'm guessing there are others out there as well. My main priorities are the ability to perform queries on large amounts of data efficiently (this thread seems to confirm Sqlite can handle this) and the ease with which I can import old data from MySQL (I remember HSQLDB being kind of a pain for that). Note: I am aware that similar questions comparing embedded databases have been posted before (for example here and here) but as my priorities differ somewhat from most applications considering the large data migration I thought it justified a new question.

• Finding data file location while using Microsoft Test Framework

  - by Nair

  I have been using NUnit and now I am switching to the Microsoft Unit Test frame work. In my test project I have a folder called TestData and I kept all my test input data files there. I want to use that files for my unit testing. In my test code, I am using Application name space and assembly name space but I can not get to the data folder directly until unless I write a code to find and replace some string to point to the data folder. I am sure someone might have run into the same problem, is the solution to change the path through program or is there a API call which will let us get to executing assembly folders? Thanks,

• Print Data Frame with Columns Center Aligned in R

  - by Glen

  I would like to print a data frame where the columns are center aligned. Below is what I have I tried, I thought printing the data frame test1 would result in the columns being aligned in the center but this is not the case. Any thoughts on how I can do this? test=data.frame(x=c(1,2,3),y=c(5,6,7)) names(test)=c('Variable 1','Variable 2') test[,1]=as.character(test[,1]) test[,2]=as.character(test[,2]) test1=format(test,justify='centre') print(test,row.names=FALSE,quote=FALSE) Variable 1 Variable 2 1 5 2 6 3 7 print(test1,row.names=FALSE,quote=FALSE) Variable 1 Variable 2 1 5 2 6 3 7

• User class - 'load' data

  - by John

  <?php class User { private $id; private $username; public function __construct($id = null) { $this->id = $id; if (!is_null($this->id)) { $this->load(); } } public function load() { } } ?> In the 'load' method I am going to load all the information from the current user (id) But I wonder how is the best way to load all info. I could grab all data and then just assign all private variables, but I assume there must be another "cheaper" way to get all the data so I can use as such $this-variable; And not have to ASSIGN every single data row, I select in the load method. How?

• How can I create a sample SQLLite DB for my iPhone app?

  - by Dr Dork

  I'm diving in to iPhone development and I'm building an iPhone app that uses the Core Data framework and my first task will be to get the model setup with a few that will display it. Thus far, I have the model defined and my Managed Object Files created, but I don't have a database with any sample data. What's a quick way to create a DB that conforms to my schema? Are there any tools that can generate a sample DB using my schemas? Is there a good tool I can use to directly manipulate the data in DB for testing purposes? Thanks in advance for your help! I'm going to continue researching this question right now.

• form data posted using linq-to-sql not showing until I refresh the page

  - by PeteShack

  I have an asp.net mvc app with a form. When you submit the form, it adds records to the sql database with linq-to-sql. After adding the records, the controller displays the form again, and should show those new values on the form. But, when it displays the form, the values are blank, until you refresh the page. While tracing through the code, I can see the records being added to the database when they are submitted, but the view doesnt display them, unless I refresh. The view is not the problem, it just displays the view model, which is missing the new records immediately after the post. I know this is kind of vague, but wasnt sure what parts of code to include here. Could this have something to do with data context life cycle? Basically, there is a data context created when the form is posted, then a different data context is created in the method that displays the form. Any suggestions on what might be causing this?

• Sending data between activities within my app?

  - by user246114

  Hi, I have a TabActivity, and the tabs point to sub activities. Is there a way I can send a 'message' to those child activities? I just want to pass a string across, not sure if this is possible. I have some data being fetched by the parent TabActivity, and the child tabs can't do anything useful until the parent is done fetching. When fetching is complete, I'd like to pass that data to the child activities so they can do something useful with it. Notmally I'd set the data to be passed in the Intent when first creating the activity, but in this case I can't do that. Thanks

• file_get_contents not displaying any data

  - by Lance

  I'm doing $info = file_get_contents('http://USERNAME:[email protected]/v2/sales?client_key=CLIENT_KEY'); $info returns nothing. However, when I put the URL into my browser, JSON appears.

• object consisting of jQuery element

  - by Adam Kiss

  hello, current code I've built function to do something over collection of jQuery elements: var collection = $([]); //empty collection I add them with: collection = collection.add(e); and remove with: collection = collection.not(e); It's pretty straightforward solution, works nicely. problem Now, I would like to have an object consisting of various settings set to any jQuery element, i.e.: function addObject(e){ var o = { alpha: .6 //float base: {r: 255, g: 255, b: 255} //color object } e.data('settings', o); } But when I pass jQuery object/element to function (i.e. as e), calling e.data doesn't work, although it would be simplest and really nice solution. question If I have an "collection" of jQuery elements, what is the simplest way of storing some data for each element of set?

• Create a table of Quantiles in R for multiple Subsets of Data

  - by user1489719

  I'm trying to create append a table of quantiles in R for multiple subsets of data. Right now, I have a vector of ids (p_ids) in table DATA, which are not consecutive. For each value in p_ids, I am looking to list the quantile. So far, I've tried variations of: i <- 1 n <- 1 for (i in p_ids) { while(n <= nrow(data)) { quantiles[n] <- quantile(subset(alldata$variableA, alldata$variableB == i),probs = c(0,1,2,3)/3) n <- n + 1 } } I know my issue lies somewhere in the index, but I can't seem to get where the index should go. Suggestions?

• Best way of obfuscating / encrypting form data on the iPhone

  - by cannyboy

  I want to create an app which holds sensitive information (imagine it's bank account details, thought it's not). The user enters this information on a form the first time the app starts up. I want this info to be saved, and available, any time the user uses the app (without having to enter a password). However, if the iPhone has a password lock on it, and is stolen, I don't want the data to be easily accessible from the file system. What is the best way of encrypting or obfuscating the data? There is not a lot of data, just a dozen NSStrings from the UITextFields on the form. I'm aware there are encryption export restrictions on the iPhone for non-US developers (I am in UK), so I would prefer to avoid going jumping through any of Apple's app submission hoops to get it on the store.

• Counting values in data frame subject to conditions

  - by unixsnob

  I have been searching around and I cannot figure out how to sumarise the data I have in my data frame (subject to some ranges). I know that it can be done when applying some combination of daaply/taaply or table but I haven't been able to get the exact result I was expecting. Basically I want to turn this: part_no val1 val2 val3 2 1 2 3 45.3 2 1 3 4 -12.3 3 1 3 4 99.3 3 1 5 2 -3.2 3 1 4 3 -55.3 Into this: part_no val3_between0_50 val3_bw50_100 val3_bw-50_0 val3_bw-100_-50 2 1 0 0 1 0 3 0 1 0 1 1 This is dummy data, I got a lot more rows, but the idea is the same. I just want to count the number of values for a participant that meet certain condition. If anyone could explain it sort of step by step, I would really appreciate it. I saw lots of different little posts around, but none do exactly this and my attempts only got me half way there. Like using table, etc. Thanks!

• jquery plugin pattern using jquery.data

  - by web_dev

  I have seen this piece of code in jquery plugin patterns and the notes section mention that we could attach the plugin to the DOM element using the jQuery.data function. What I don't understand is how do I make use of this piece of code. Can somebody provide examples of how to use this functionality and explain its significance? $.fn[pluginName] = function (options) { return $Extend(this).each(function () { if (!$.data(this, 'plugin_' + pluginName)) { $.data(this, 'plugin_' + pluginName, new Plugin( this, options )); } }); };

• How do i generate random data with RSA?

  - by acidzombie24

  After loading my RSACryptoServiceProvider rsa object i would like to create a key for my AES object. Since i dont need to store the AES key (i only need it to decrypt on my prv side) i figure i dont need to store it and i can generate it with my public key. I thought doing rsa.Encrypt(byte[] with 4 hardcoded bytes); would generate the data i need. It turns out everytime i call this function even with the same data i get different results. So theres no way for me to recreate the AES key if its different everytime. How can i generate data with RSA in a way that i can recreate anytime i need?

• Can single-buffer blocking WSASend deliver partial data?

  - by CodeAngry

  I've pretty much always used send() with sockets and now I'm moving onto the WSA functions. With send(), I have a sendall() helper that ensured all data is delivered even if it didn't happen in one try and a partial send occurred on first call. So, instead of learning the hard way or over-complicating code when I don't have to, decided to ask you: Can a blocking WSASend() send partial data or does it send everything before it returns or fails? Or should I check the bytes sent vs. expected to send and keep at it until everything is delivered? ANSWER: Overlapped WSASend() does not send partial data but if it does, it means the connection has terminated. I've never encountered the case yet.

• Creating Oracle stored procedure that returns data

  - by user3614327

  In Firebird you can create a stored procedure that returns data an invoke it like a table passing the arguments: create or alter procedure SEL_MAS_IVA ( PCANTIDAD double precision) returns ( CANTIDAD_CONIVA double precision) as begin CANTIDAD_CONIVA = pCANTIDAD*(1.16); suspend; end select * from SEL_MAS_IVA(100) will return a single row single column (named CANTIDAD_CONIVA) relation with the value 116 This is a very simple example. The stored procedure can of course have any number of input and output parameters and do whatever it needs to return data (including multiple rows), which is accomplished by the "suspend" statement (which as it name implies, suspends the SP execution, returns data to the caller, and resumes with the next statement) How can I create such kind of stored procedures in Oracle?

• JQuery .get() only passing first two data parameters in url

  - by The.Anti.9

  I have a $.get() call to a PHP page that takes 4 GET parameters. For some reason, despite giving the $.get() call all 4, it only passes the first two. When I look at the dev console in chrome, it shows the URL that gets called, and it only passes action and dbname. Heres the code: $.get('util/util.php', { action: 'start', dbname: db, url: starturl, crawldepth: depth }, function(data) { if (data == 'true') { status = 1; $('#0').append(starturl + "<ul></ul>"); $('#gobutton').hide(); $('#loading').show("slow"); while(status == 1) { setTimeout("update()",10000); } } else { show_error("Form data incomplete!"); } }); and heres the URL that I see in the developer console: http://localhost/pci/util/util.php?action=start&dbname=1hkxorr9ve1kuap2.db

• iPhone App/Java Server Struct Data Issue over WiFi

  - by adimitri

  I currently have an iPhone app that communicates with a C++ server running on a computer, over WiFi. This app is sending its data (x,y coordinates) in a c-struct to the server. For further development, we would like the iPhone application to communicate directly with a java server, however the major issue is that java does not have the ability to emulate or use a c-struct. What would be the best way to send data (x,y coordinates) between the two devices? I can already establish a connection between the two devices. More specifically how I would receive the data and process it on the Java end. Thanks for your help, Alex
