  • bing search api ajax does not work

    - by jhon
    Hi guys, I want to use the Bing's search api with javascript. Actually, I want the user to write something and query Bing in order to get just images. so, I tried it using ajax. If I try the url http://api.search.live.net/xml.aspx?Appid=[YOURAPIKEY]&sources=image&query=home directly (with the browser) I do get an xml document. but if I use XMLHttpRequest it does not work. <html> <body> <script> var xhr = new XMLHttpRequest(); var url="http://api.search.live.net/xml.aspx?Appid=[YOURAPIKEY]&sources=image&query=home" xhr.open("GET", url, true ); xhr.onreadystatechange=function(){ /*if( xhr.readyState == 4 && xhr.status == 200) { document.write( xhr.responseText ); }*/ alert( xhr.readyState +" "+xhr.status +xhr.statusText +xhr); }; xhr.send(null); </script> </body> </html> Questions: 1) why does the code from above does not work? 2) any other way to do this without XMLHttpRequest? thanks. btw. I'm just interested in fix this for Firefox and without external libraries (jquery and so on).

  • Login with Kohana auth module - what am I doing wrong?

    - by keithjgrant
    I'm trying to login with the following controller action, but my login attempt keeps failing (I get the 'invalid username and/or password' message). What am I doing wrong? I also tried the other method given in the examples in the auth documentation, Auth::instance()->login($user->username, $form->password);, but I get the same result. Kohana version is 2.3.4. public function login() { $auth = Auth::instance(); if ($auth->logged_in()) { url::redirect('/account/summary'); } $view = new View('login'); $view->username = ''; $view->password = ''; $post = $this->input->post(); $form = new Validation($post); $form->pre_filter('trim', 'username') ->pre_filter('trim', 'password') ->add_rules('username', 'required'); $failed = false; if (!empty($post) && $form->validate()) { $login = array( 'username' => $form->username, 'password' => $form->password, ); if (ORM::factory('user')->login($login)) { url::redirect('/accounts/summary'); } else { $view->username = $form->username; $view->message = in_array('required', $form->errors()) ? 'Username and password are required.' : 'Invalid username and/or password.'; } } $view->render(true); }

  • PHP script not automatically updating when moved to another server

    - by user32007
    A friend built a ranking system on his site and I am trying to host in on mine via WordPress and Go Daddy. It updates for him but when I load it to my site, it works for 6 hours, but as soon as the reload is supposed to occur, it errors and I get a 500 timeout error. His page is at: jeremynoeljohnson .com/yakezieclub My page is currently at http://sweatingthebigstuff.com/yakezieclub but when you ?reload=1 it will give the error. Any idea why this might be happening? Any settings that I might need to change? Here is the top of the index.php file. I'm not sure which part of any of it is messing up. I literally uploaded the same code as him. Here's the reload part: $cachefile = "rankings.html"; $daycachefile = "rankings_history.xml"; $cachetime = (60 * 60) * 6; // every 6 hours, the cache refreshes $daycachetime = (60 * 60) * 24; // every 24 hours, the history will be written to // - or whenever the page is requested after 24 hours has passed $writenewdata = false; if (!empty($_GET['reload'])) { if ($_GET['reload']== 1) { $cachetime = 1; } } if (!empty($_GET['reloadhistory'])) { if ($_GET['reloadhistory'] == 1) { $daycachetime = 1; $cachetime = 1; } } if (file_exists($daycachefile) && (time() - $daycachetime < filemtime($daycachefile))) { // Do nothing } else { $writenewdata = true; $cachetime = 1; } // Serve from the cache if it is younger than $cachetime if (file_exists($cachefile) && (time() - $cachetime < filemtime($cachefile))) { include($cachefile); echo "<!-- Cached ".date('jS F Y H:i', filemtime($cachefile))." -->"; exit; } ob_start(); // start the output buffer ?>

  • Serializing a DataType="time" field using XmlSerializer

    - by CraftyFella
    Hi, I'm getting an odd result when serializing a DateTime field using XmlSerializer. I have the following class: public class RecordExample { [XmlElement("TheTime", DataType = "time")] public DateTime TheTime { get; set; } [XmlElement("TheDate", DataType = "date")] public DateTime TheDate { get; set; } public static bool Serialize(Stream stream, object obj, Type objType, Encoding encoding) { try { using (var writer = XmlWriter.Create(stream, new XmlWriterSettings { Encoding = encoding })) { var xmlSerializer = new XmlSerializer(objType); if (writer != null) xmlSerializer.Serialize(writer, obj); } return true; } catch (Exception) { return false; } } } When i call the use the XmlSerializer with the following testing code: var obj = new RecordExample {TheDate = DateTime.Now.Date, TheTime = new DateTime(0001, 1, 1, 12, 00, 00)}; var ms = new MemoryStream(); RecordExample.Serialize(ms, obj, typeof (RecordExample), Encoding.UTF8); txtSource2.Text = Encoding.UTF8.GetString(ms.ToArray()); I get some strange results, here's the xml that is produced: <?xml version="1.0" encoding="utf-8"?> <RecordExample xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:xsd="http://www.w3.org/2001/XMLSchema"> <TheTime>12:00:00.0000000+00:00</TheTime> <TheDate>2010-03-08</TheDate> </RecordExample> Any idea's how i can get the "TheTime" element to contain a time which looks more like this: <TheTime>12:00:00.0Z</TheTime> ...as that's what i was expecting? Thanks Dave

  • How to set connection string dynamically in NHibernate

    Hi I want assign connection string for NHibernate using following code and getting exception (bold). log4net.Config.DOMConfigurator.Configure(); Configuration config = new Configuration(); IDictionary props = new Hashtable(); props["hibernate.connection.provider"] = "NHibernate.Connection.DriverConnectionProvider"; props["hibernate.dialect"] = "NHibernate.Dialect.MsSql2000Dialect"; props["hibernate.connection.driver_class"] = "NHibernate.Driver.SqlClientDriver"; props["hibernate.connection.connection_string"] = @"Integrated Security=SSPI;Persist Security Info=False;Initial Catalog=Sample;Data Source=HYDHTC92318D\SQLEXPRESS"; props["hibernate.connection.current_session_context_class"] = "web"; props["hibernate.connection.show_sql"] = "true"; props["hibernate.connection.proxyfactoryfactory.factory_class"] = "NHibernate.ByteCode.Castle.ProxyFactoryFactory, NHibernate.ByteCode.Castle"; foreach (DictionaryEntry de in props) { config.SetProperty(de.Key.ToString(), de.Value.ToString()); } config.AddAssembly("nhibernator"); factory = config.BuildSessionFactory(); session = factory.OpenSession(); The ProxyFactoryFactory was not configured.

  • Javascript: "Dangling" Reference to DOM element?

    - by Channel72
    It seems that in Javascript, if you have a reference to some DOM element, and then modify the DOM by adding additional elements to document.body, your DOM reference becomes invalidated. Consider the following code: <html> <head> <script type = "text/javascript"> function work() { var foo = document.getElementById("foo"); alert(foo == document.getElementById("foo")); document.body.innerHTML += "<div>blah blah</div>"; alert(foo == document.getElementById("foo")); } </script> </head> <body> <div id = "foo" onclick='work()'>Foo</div> </body> </html> When you click on the DIV, this alerts "true", and then "false." So in other words, after modifying document.body, the reference to the DIV element is no longer valid. This behavior is the same on Firefox and MSIE. Some questions: Why does this occur? Is this behavior specified by the ECMAScript standard, or is this a browser-specific issue? Note: there's another question posted on stackoverflow that seems to be referring to the same issue, but neither the question nor the answers are very clear.

  • Running commands over ssh with Java

    - by Ichorus
    Scenerio: I'd like to run commands on remote machines from a Java program over ssh (I am using OpenSSH on my development machine). I'd also like to make the ssh connection by passing the password rather than setting up keys as I would with 'expect'. Problem: When trying to do the 'expect' like password login the Process that is created with ProcessBuilder cannot seem to see the password prompt. When running regular non-ssh commands (e.g 'ls') I can get the streams and interact with them just fine. I am combining standard error and standard out into one stream with redirectErrorStream(true); so I am not missing it in standard error...When I run ssh with the '-v' option, I see all of the logging in the stream but I do not see the prompt. This is my first time trying to use ProcessBuilder for something like this. I know it would be easier to use Python, Perl or good ol' expect but my boss wants to utilize what we are trying to get back (remote log files and running scripts) within an existing Java program so I am kind of stuck. Thanks in advance for the help!

  • Java: Efficiency of the readLine method of the BufferedReader and possible alternatives

    - by Luhar
    We are working to reduce the latency and increase the performance of a process written in Java that consumes data (xml strings) from a socket via the readLine() method of the BufferedReader class. The data is delimited by the end of line separater (\n), and each line can be of a variable length (6KBits - 32KBits). Our code looks like: Socket sock = connection; InputStream in = sock.getInputStream(); BufferedReader inputReader = new BufferedReader(new InputStreamReader(in)); ... do { String input = inputReader.readLine(); // Executor call to parse the input thread in a seperate thread }while(true) So I have a couple of questions: Will the inputReader.readLine() method return as soon as it hits the \n character or will it wait till the buffer is full? Is there a faster of picking up data from the socket than using a BufferedReader? What happens when the size of the input string is smaller than the size of the Socket's receive buffer? What happens when the size of the input string is bigger than the size of the Socket's receive buffer? I am getting to grips (slowly) with Java's IO libraries, so any pointers are much appreciated. Thank you!

  • How do I sign requests reliably for the Last.fm api in C#?

    - by Arda Xi
    I'm trying to implement authorization through Last.fm. I'm submitting my arguments as a Dictionary to make the signing easier. This is the code I'm using to sign my calls: public static string SignCall(Dictionary<string, string> args) { IOrderedEnumerable<KeyValuePair<string, string>> sortedArgs = args.OrderBy(arg => arg.Key); string signature = sortedArgs.Select(pair => pair.Key + pair.Value). Aggregate((first, second) => first + second); return MD5(signature + SecretKey); } I've checked the output in the debugger, it's exactly how it should be, however, I'm still getting WebExceptions every time I try. Here's my code I use to generate the URL in case it'll help: public static string GetSignedURI(Dictionary<string, string> args, bool get) { var stringBuilder = new StringBuilder(); if (get) stringBuilder.Append("http://ws.audioscrobbler.com/2.0/?"); foreach (var kvp in args) stringBuilder.AppendFormat("{0}={1}&", kvp.Key, kvp.Value); stringBuilder.Append("api_sig="+SignCall(args)); return stringBuilder.ToString(); } And sample usage to get a SessionKey: var args = new Dictionary<string, string> { {"method", "auth.getSession"}, {"api_key", ApiKey}, {"token", token} }; string url = GetSignedURI(args, true); EDIT: Oh, and the code references an MD5 function implemented like this: public static string MD5(string toHash) { byte[] textBytes = Encoding.UTF8.GetBytes(toHash); var cryptHandler = new System.Security.Cryptography.MD5CryptoServiceProvider(); byte[] hash = cryptHandler.ComputeHash(textBytes); return hash.Aggregate("", (current, a) => current + a.ToString("x2")); }

  • {DCC Warning} W1036 Variable '$frame' might not have been initialized?

  • RichFaces a4j:support parameter passing

    - by Mark Lewis
    Hello I have a number of rich:inplaceInput tags in RichFaces which represent numbers in an array. The validator allows integers only. When a user clicks in an input and changes a value, how can I get the bean to sort the array given the new number and reRender the list of rich:inplaceInput tags so that they're in numerical order? EG <a4j:region> <rich:dataTable value="#{MyBacking.config}" var="feed" cellpadding="0" cellspacing="0" width="100%" border="0" columns="5" id="Admin"> ... <a4j:repeat... <a4j:region id="MsgCon"> <rich:inplaceInput value="#{h.id}" validator="#{MyBacking.validateID}" id="andID" showControls="true"> <a4j:support event="onviewactivated" action="#{MyBacking.sort}" reRender="Admin" /> </rich:inplaceInput> </a4j:region> </a4j:repeat> </data:Table> </a4j:region> Note I do NOT want to use dataTable sort functions. The table is complicated and I've specified id="Admin" (ie the whole table) to reRender as I've not found a way to send more localised values to the backing bean through the inplaceInput. This question is about how to use a4j:support action attribute to call the sort method so that when the reRender rerenders the component, it outputs the list in sorted order. I have the sort method working ok when I click a button to sort, but I want to have the list sorted automatically as soon as a new valid value is entered into the inplaceInput component. Thanks

  • PHP (CodeIgniter) Pass Object Through Session

    - by FranticPedantic
    I am using PHP5 and CodeIgniter and I am trying to implement a single-sign on feature with facebook (although I don't think that facebook is relevant to the question). I am somewhat of a novice with PHP and definitely one with CodeIgniter, so if you think my approach is just completely off telling me that would be helpful too. So here is in short what I am doing: //Controller 1 $this->load->plugin("facebook"); $facebook = new Facebook(array ( 'appId' => $fbconfig['appid'], 'secret' => $fbconfig['secret'], 'cookie' => true, ) ); $fbsession = $facebook->getSession(); //works fine $this->session->set_userdata('facebook', serialize($facebook); Now I would like to grab that facebook object in a different controller. //Controller 2 $facebook = unserialize($this->session->userdata('facebook')); $fbsession = $facebook->getSession(); Produces the error: Call to undefined method getSession. So I look up more about serialization and think that maybe it just doesn't know what the facebook object's attributes are. So I add in a $this->load->plugin('facebook'); To controller 2 as well and I get a "Cannot redeclare class facebook." I am strongly suspecting that I am misunderstanding sessions here. Do I have to somehow tell PHP what kind of object it is? Thanks for the help.

  • Customize jQuery.aptags plugin - mouseclick submit from .ac_results list

    - by atmorell
    Hello, I am using jquery.autocomplete.js and jquery.apitags to select a few elements from a div (.ac_results) This works great, and I can select multiple elements etc. However the jquery-aptags plugin does only fire when enter is pressed. This might confuse some users if they use the mouse to click instead of the arrows/enter on the keyboard. I think this is the code inside jquery.aptags that submits the tag. // // Hook to the keypress event. // $(this).bind('keypress', { __c: __c }, function (e) { var c = ''; var i = 0; var v = $(this).val(); if (e.keyCode == 13) { e.stopPropagation(); e.preventDefault(); __createSpans(this, v, e.data.__c, true); } }); I am wondering if it is possible to call the method directly from a new event. $('.ac_results > ul > li').livequery(function() { $(this).bind('click', function() { $('#address_city'). //how do I fire the "enter" event from here? }); }); Any thoughts?

  • Compile time float packing/punning

    - by detly
    I'm writing C for the PIC32MX, compiled with Microchip's PIC32 C compiler (based on GCC 3.4). My problem is this: I have some reprogrammable numeric data that is stored either on EEPROM or in the program flash of the chip. This means that when I want to store a float, I have to do some type punning: typedef union { int intval; float floatval; } IntFloat; unsigned int float_as_int(float fval) { IntFloat intf; intf.floatval = fval; return intf.intval; } // Stores an int of data in whatever storage we're using void StoreInt(unsigned int data, unsigned int address); void StoreFPVal(float data, unsigned int address) { StoreInt(float_as_int(data), address); } I also include default values as an array of compile time constants. For (unsigned) integer values this is trivial, I just use the integer literal. For floats, though, I have to use this Python snippet to convert them to their word representation to include them in the array: import struct hex(struct.unpack("I", struct.pack("f", float_value))[0]) ...and so my array of defaults has these indecipherable values like: const unsigned int DEFAULTS[] = { 0x00000001, // Some default integer value, 1 0x3C83126F, // Some default float value, 0.005 } (These actually take the form of X macro constructs, but that doesn't make a difference here.) Commenting is nice, but is there a better way? It's be great to be able to do something like: const unsigned int DEFAULTS[] = { 0x00000001, // Some default integer value, 1 COMPILE_TIME_CONVERT(0.005), // Some default float value, 0.005 } ...but I'm completely at a loss, and I don't even know if such a thing is possible. Notes Obviously "no, it isn't possible" is an acceptable answer if true. I'm not overly concerned about portability, so implementation defined behaviour is fine, undefined behaviour is not (I have the IDB appendix sitting in front of me). As fas as I'm aware, this needs to be a compile time conversion, since DEFAULTS is in the global scope. Please correct me if I'm wrong about this.

  • Thread to receive the messages from serial port is not working using c#

    - by karthik
    I am using Serial port to receive the messages. The below function is running in a thread. When i debug i find that the thread is running properly. But "if (sp.IsOpen)" is always false, due to which the code is not executing inside the IF condition at all. It says the Port is closed. I will be having multiple serial ports in my system and i will not know, which port will receive the message. So i need to listen to all the ports in one Thread. How can i solve my problem here ? private void ListenerPorts() { log.Info("Listening Thread Started"); while (true) { //foreach (SerialPort sp in storeport) foreach (SerialPort sp in comPortsList) { if (sp.IsOpen) { sp.ReadTimeout = readTimeoutInMs; sp.WriteTimeout = writeTimeoutInMs; try { string msg = sp.ReadLine(); this.GetMessageRichTextBox("Message : " + msg + "\n"); sp.WriteLine(sp.PortName); if (msg.Contains("COM")) { // is AutoScan receiverPortName = sp.ReadLine(); this.updateLblStatusRichTextBox(sp.PortName + " is connected to " + msg + "\n"); } else { //standalone is uppercase ReceiverPortName = sp.ReadLine(); this.updateLblStatusRichTextBox(sp.PortName + " is connected to " + ReceiverPortName + "\n"); } } catch (Exception ex) { // no data System.Diagnostics.Debug.WriteLine(sp.PortName + " : " + ex.Message); } } } } }

  • Android map overly transparency has unwanted gradient

    - by DavidP2190
    I'm a making my first android app and for part of it I need some shaded areas over a mapview. I've got this working so far but the when I set the alpha of the fill colour, it goes strange. I'm not allowed to post images yet, but you can see what happens here: http://i.imgur.com/leXmc.png I'm not sure what causes it, but here is some code from where it gets drawn. public boolean draw(Canvas canvas, MapView mapView, boolean shadow, long when) { Paint paint = new Paint(); paint.setStrokeWidth(2); paint.setColor(android.graphics.Color.GREEN); paint.setStyle(Paint.Style.FILL_AND_STROKE); paint.setAlpha(25); screenPoints = new Point[10]; Path path = new Path(); for (int x = 0; x<greenZone.length; x++){ screenPoints[x] = new Point(); mapView.getProjection().toPixels(greenZone[x], screenPoints[x]); } path.moveTo(screenPoints[0].x, screenPoints[0].y); for (int x = 1; x < screenPoints.length-1; x++){ paint.setAlpha(25); if (x<9){ path.lineTo(screenPoints[x].x, screenPoints[x].y); canvas.drawPath(path, paint); } else{ path.moveTo(screenPoints[screenPoints.length-1].x, screenPoints[screenPoints.length-1].y); path.lineTo(screenPoints[0].x, screenPoints[0].y); canvas.drawPath(path, paint); } } return true; } Thanks.

  • Copy a multi-dimentional array by Value (not by reference) in PHP.

    - by Simon R
    Language: PHP I have a form which asks users for their educational details, course details and technical details. When the form is submitted the page goes to a different page to run processes on the information and save parts to a database. HOWEVER(!) I then need to return the page back to the original page, where having access to the original post information is needed. I thought it would be simple to copy (by value) the multi-dimensional (md) $_POST array to $_SESSION['post'] session_start(); $_SESSION['post'] = $_POST; However this only appears to place the top level of the array into $_SESSION['post'] not doing anything with the children/sub-arrays. An abbreviated form of the md $_POST array is as follows: Array ( [formid] = 2 [edu] = Array ( ['id'] = Array ( [1] = new_1 [2] = new_2 ) ['nameOfInstitution'] = Array ( [1] = 1 [2] = 2 ) ['qualification'] = Array ( [1] = blah [2] = blah ) ['grade'] = Array ( [1] = blah [2] = blah ) ) [vID] = 61 [Submit] = Save and Continue ) If I echo $_SESSION['post']['formid'] it writes "2", and if I echo $_SESSION['post']['edu'] it returns "Array". If I check that edu is an array (is_array($_SESSION['post']['edu])) it returns true. If I echo $_SESSION['post']['edu']['id'] it returns array, but when checked (is_array($_SESSION['post']['edu]['id'])) it returns false and I cannot echo out any of the elements. How do I successfully copy (by value, not by reference) the whole array (including its children) to an new array?

  • Handling form from different view and passing form validation through session in django

    - by Mo J. Mughrabi
    I have a requirement here to build a comment-like app in my django project, the app has a view to receive a submitted form process it and return the errors to where ever it came from. I finally managed to get it to work, but I have doubt for the way am using it might be wrong since am passing the entire validated form in the session. below is the code comment/templatetags/comment.py @register.inclusion_tag('comment/form.html', takes_context=True) def comment_form(context, model, object_id, next): """ comment_form() is responsible for rendering the comment form """ # clear sessions from variable incase it was found content_type = ContentType.objects.get_for_model(model) try: request = context['request'] if request.session.get('comment_form', False): form = CommentForm(request.session['comment_form']) form.fields['content_type'].initial = 15 form.fields['object_id'].initial = 2 form.fields['next'].initial = next else: form = CommentForm(initial={ 'content_type' : content_type.id, 'object_id' : object_id, 'next' : next }) except Exception as e: logging.error(str(e)) form = None return { 'form' : form } comment/view.py def save_comment(request): """ save_comment: """ if request.method == 'POST': # clear sessions from variable incase it was found if request.session.get('comment_form', False): del request.session['comment_form'] form = CommentForm(request.POST) if form.is_valid(): obj = form.save(commit=False) if request.user.is_authenticated(): obj.created_by = request.user obj.save() messages.info(request, _('Your comment has been posted.')) return redirect(form.data.get('next')) else: request.session['comment_form'] = request.POST return redirect(form.data.get('next')) else: raise Http404 the usage is by loading the template tag and firing {% comment_form article article.id article.get_absolute_url %} my doubt is if am doing the correct approach or not by passing the validated form to the session. Would that be a problem? security risk? performance issues? Please advise Update In response to Pol question. The reason why I went with this approach is because comment form is handled in a separate app. In my scenario, I render objects such as article and all I do is invoke the templatetag to render the form. What would be an alternative approach for my case? You also shared with me the django comment app, which am aware of but the client am working with requires a lot of complex work to be done in the comment app thats why am working on a new one.

  • Resume Activity with back button

    - by Hallik
    I have an application I am creating with a DashboardActivity & a SettingsActivity. On the dashboard, I have one object displayed, but when I go into settings, I want to be able to select/deselect X options. Once the user clicks the back button, I save that data locally and to the server. Once the phone receives a success message from the server that it was stored properly, I want to reload the dashboard. I thought I would do this with the onPause and onResume, but they are called when the DashboardActivity is first created. What would be the best way to reload the dashboard by calling my web service after the settings were saved to the server? Here is what I am doing when the back button is hit @Override public boolean onKeyDown(int keyCode, KeyEvent event) { //Save data to the server once the user hits the back button if ((keyCode == KeyEvent.KEYCODE_BACK)) { SchoolSearchActivity.this.divisionProxy = new DivisionProxy(SchoolSearchActivity.this.saveUserDivisionHandler); SchoolSearchActivity.this.divisionProxy.submitUserDivisions(SchoolSearchActivity.this.userDivisions, SchoolSearchActivity.this.user_id); //SchoolSearchActivity.this.finish(); //Toast.makeText(SchoolSearchActivity.this, "Divisions Saved",Toast.LENGTH_LONG).show(); } return true; } The above opens an HTTP connection, and when the response is received, the handler processes the response. I am going to: 1) throw up a progress dialog box letting the user know it's being submitted to the server, and once a response is received, 2) go back to the previous activity and call the "refresh" webservice again. What's the best way to accomplish 1 & 2?
