  • Is it possible to create a Service that listens for hardware key presses?

    - by VoteBrian
    I'd like to run an Android background service that will act as a keylistener from the home screen or when the phone is asleep. Is this possible? From semi-related examples online, I put together the following service, but get the error, "onKeyDown is undefined for the type Service" public class ServiceName extends Service { @Override public void onCreate() { //Stuff } public IBinder onBind(Intent intent) { //Stuff return null; } @Override public boolean onKeyDown(int keyCode, KeyEvent event) { if(event.getAction() == KeyEvent.ACTION_DOWN) { switch(keyCode) { case KeyEvent.KEYCODE_A: //Stuff return true; case KeyEvent.KEYCODE_B: //Stuff return true; //etc. } } return super.onKeyDown(keyCode, event); } } I realize Android defaults to the search bar when you type from the home screen, but this really is just for a very particular use. I don't really expect to distribute this. Also, it'd be nice to use the camera button to wake the phone.

  • ActiveRecord date format

    - by Mongus Pong
    I've run into a spot of bother with date formats in our Rails application. I have a date field in our view which I want to be formatted as dd/mm/yy. This is how the user will expect to enter their dates, and the datepicker control uses this format. However, Active Record seems to be expecting mm/dd/yy. If I enter 01/03/2010, this gets put in as 03 January 2010. If I enter 25/03/2010, this gets put in a null. How do I get ActiveRecord to expect Her Majesties date format?

  • 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?

  • Do fields need to be explicitly final to have a "proper" immutable object?

    - by Yishai
    You often read about immutable objects requiring final fields to be immutable in Java. Is this in fact the case, or is it simply enough to have no public mutability and not actually mutate the state? For example, if you have an immutable object built by the builder pattern, you could do it by having the builder assign the individual fields as it builds, or having the builder hold the fields itself and ultimately return the immutable object by passing the values to its (private) constructor. Having the fields final has the obvious advantage of preventing implementation errors (such as allowing code to retain a reference to the builder and "building" the object multiple times while in fact mutating an existing object), but having the Builder store its data inside the object as it is built would seem to be DRYer. So the question is: Assuming the Builder does not leak the Object early and stops itself from modifying the object once built (say by setting its reference to the object as null) is there actually anything gained (such as improved thread safety) in the "immutability" of the object if the object's fields were made final instead?

  • Trying to call JS Code that is passed back from AJAX call....

    - by Dutchie432
    Okay, so I have an javascript function that retrieves some HTML... function updateQuestions(i){ var url = 'getQuestions.php?sys=' + i; if (receiveReq.readyState == 4 || receiveReq.readyState == 0) { receiveReq.open("GET", url, true); receiveReq.onreadystatechange = handleQuestionsUpdate; receiveReq.send(null); } } function handleQuestionsUpdate() { if (receiveReq.readyState == 4) { var a=receiveReq.responseText; document.getElementById('questions').innerHTML=a; checkSpeakers(); //Error Occurs Here, even though checkSpeakers() is a function in the returned HTML chunk. } } This HTML is not just HTML, but it is more specifically a form and a chunk of javascript. The javascript is hard-coded into the HTML and not referenced by <script src=".."> Is it normal that this retrieved JS code isn't recognized upon call-time? If so, what is my alternative if I need the JS to change every time the div is update? Now

  • My cookies won't stay (PHP).

    - by RemiX
    I'm building an autologin system using cookies, but one fundamental part of the functionality of the cookies fails: they are non-persistent over different sessions - or even pages! In my login script, I set the cookies like this: setcookie('userID', $userID, time()+86400); // (edited after replies) $userID has a value. Then I print the $_COOKIE variable and it says array(['base_usid'] = 1); So that's good, but when I click the home page and print the $_COOKIE variable there, it says NULL. Does anyone see the problem?

  • Access violation C++ (Deleting items in a vector)

    - by Gio Borje
    I'm trying to remove non-matching results from a memory scanner I'm writing in C++ as practice. When the memory is initially scanned, all results are stored into the _results vector. Later, the _results are scanned again and should erase items that no longer match. The error: Unhandled exception at 0x004016f4 in .exe: 0xC0000005: Access violation reading location 0x0090c000. // Receives data DWORD buffer; for (vector<memblock>::iterator it = MemoryScanner::_results.begin(); it != MemoryScanner::_results.end(); ++it) { // Reads data from an area of memory into buffer ReadProcessMemory(MemoryScanner::_hProc, (LPVOID)(*it).address, &buffer, sizeof(buffer), NULL); if (value != buffer) { MemoryScanner::_results.erase(it); // where the program breaks } }

    - by RobertR
    Hello, world! I'm trying to build a little bit advanced users system using Joomla, but I stuck at one spot. I added new field on Joomla's jos_users table, but when I wanted to get that field out, like "echo" - it didn't worked at all. Any other data, even password field I can get without problems. Of course, I added new value in /var/www/<project>/libraries/joomla/user/user.php like this after line 40. /** * The users address name * @var string */ var $address = null; What might be the problem here? Or what I did wrong, or what I didn't do at all? Thanks for replies! Cheerio

  • Mysql with innodb and serializable transaction does not (always) lock rows

    - by Tobias G.
    Hello, I have a transaction with a SELECT and possible INSERT. For concurrency reasons, I added FOR UPDATE to the SELECT. To prevent phantom rows, I'm using the SERIALIZABLE transaction isolation level. This all works fine when there are any rows in the table, but not if the table is empty. When the table is empty, the SELECT FOR UPDATE does not do any (exclusive) locking and a concurrent thread/process can issue the same SELECT FOR UPDATE without being locked. CREATE TABLE t ( id INT NOT NULL AUTO_INCREMENT PRIMARY KEY, display_order INT ) ENGINE = InnoDB; SET TRANSACTION ISOLATION LEVEL SERIALIZABLE; START TRANSACTION; SELECT COALESCE(MAX(display_order), 0) + 1 from t FOR UPDATE; .. This concept works as expected with SQL Server, but not with MySQL. Any ideas on what I'm doing wrong? EDIT Adding an index on display_order does not change the behavior.

  • nextSibling issue, should be simple

    - by SoLoGHoST
    Ok, I'm trying to come to grips with this nextSibling function in JS. Here's my issue within the following code... var fromRow = document.getElementById("row_1"); while(fromRow.nodeType == 1 && fromRow.nextSibling != null) { var fRowId = fromRow.id; if (!fRowId) continue; // THIS ONLY gets done once and alerts "row_1" ONLY :( alert(fRowId); fromRow = fromRow.nextSibling; } Ok can someone please tell me what is wrong with this code? There are siblings next to this document.getElementById("row_1"); element for sure as I can see them, and they all have id attributes, so why is it not getting the id attributes of the siblings?? I don't get it. row_1 is a TR element, and I need to get the TR elements next to it within this table, but for some reason, it only gets the 1 element that I can already get using document.getElementById, arggg. Thanks guys :)
