  • Implicit Type Conversions in Reflection

    - by bradhe
    So I've written a quick bit of code to help quickly convert between business objects and view models. Not to pimp my own blog, but you can find the details here if you're interested or need to know. One issue I've run in to is that I have a custom collection type, ProductCollection, and I need to turn that in to a string[] in on my model. Obviously, since there is no default implicit cast, I'm getting an exception in my contract converter. So, I thought I would write the next little bit of code and that should solve the problem: public static implicit operator string[](ProductCollection collection) { var list = new List<string>(); foreach (var product in collection) { if (product.Id == null) { list.Add(null); } else { list.Add(product.Id.ToString()); } } return list.ToArray(); } However, it still fails with the same cast exception. I'm wondering if it has something to do with being in reflection? If so, is there anything that I can do here?? I'm open to architectural solutions, too!

  • make a thread which recieves values from other threads

    - by farteaga88
    This program in Java creates a list of 15 numbers and creates 3 threads to search for the maximum in a given interval. I want to create another thread that takes those 3 numbers and get the maximum. but i don't know how to get those values in the other thread. public class apple implements Runnable{ String name; int time, number, first, last, maximum; int[] array = {12, 32, 54 ,64, 656, 756, 765 ,43, 34, 54,5 ,45 ,6 , 5, 65}; public apple(String s, int f, int l){ name = s; first = f; last = l; maximum = array[0]; } public void run(){ try{ for(int i = first; i < last; i++ ) { if(maximum < array[i]) { maximum = array[i]; } } System.out.println("Thread"+ name + "maximum = " + maximum); }catch(Exception e){} } public static void main(String[] args){ Thread t1 = new Thread(new apple("1 ", 0, 5)); Thread t2 = new Thread(new apple("2 ", 5, 10 )); Thread t3 = new Thread(new apple("3 ", 10, 15)); try{ t1.start(); t2.start(); t3.start(); }catch(Exception e){} } }

  • Unit testing, mocking - simple case: Service - Repository

    - by rafek
    Consider a following chunk of service: public class ProductService : IProductService { private IProductRepository _productRepository; // Some initlization stuff public Product GetProduct(int id) { try { return _productRepository.GetProduct(id); } catch (Exception e) { // log, wrap then throw } } } Let's consider a simple unit test: [Test] public void GetProduct_return_the_same_product_as_getProduct_on_productRepository() { var product = EntityGenerator.Product(); _productRepositoryMock.Setup(pr => pr.GetProduct(product.Id)).Returns(product); Product returnedProduct = _productService.GetProduct(product.Id); Assert.AreEqual(product, returnedProduct); _productRepositoryMock.VerifyAll(); } At first it seems that this test is ok. But let's change our service method a little bit: public Product GetProduct(int id) { try { var product = _productRepository.GetProduct(id); product.Owner = "totallyDifferentOwner"; return product; } catch (Exception e) { // log, wrap then throw } } How to rewrite a given test that it'd pass with the first service method and fail with a second one? How do you handle this kind of simple scenarios? HINT: A given test is bad coz product and returnedProduct is actually the same reference.

  • Robust DateTime parser library for .NET

    - by Frank Krueger
    Hello, I am writing an RSS and Mail reader app in C# (technically MonoTouch). I have run into the issue of parsing DateTimes. I see a lot of variance in how dates are presented in the wild and have begun writing a function like this: public static DateTime ParseTime(string timeStr) { var formats = new string[] { "ddd, d MMM yyyy H:mm:ss \"GMT+00:00\"", "d MMM yyyy H:mm:ss \"EST\"", "yyyy-MM-dd\"T\"HH:mm:ss\"Z\"", "ddd MMM d HH:mm:ss \"+0000\" yyyy", }; try { return DateTime.Parse(timeStr); } catch (Exception) { } foreach (var f in formats) { try { var t = DateTime.ParseExact(timeStr, f, CultureInfo.InvariantCulture); return t; } catch (Exception) { } } return DateTime.MinValue; } This, well, makes me sick. Three points. (1) It's silly of me to think that I can actually collect a format list that will cover everything out there. (2) It's wrong! Notice that I'm treating an EST date time as UTC (since .NET seems oblivious to time zones). (3) I don't like using exceptions for logic. I am looking for an existing library (source only please) that is known to handle a bunch of these formats. Also, I would like to keep using UTC DateTimes throughout my code so whatever library is suggested should be able to produce DateTimes. Is there anything out there like this?

  • How Can I Find a List of All Exceptions That a Given Library Function Throws in Python?

    - by b14ck
    Sorry for the long title, but it seems most descriptive for my question. Basically, I'm having a difficult time finding exception information in the official python documentation. For example, in one program I'm currently writing, I'm using the shutil libary's move function: from shutil import move move('somefile.txt', '/tmp/somefile.txt') That works fine, as long as I have write access to /tmp/, there is enough diskspace, and if all other requirements are satisfied. However, when writing generic code, it is often difficult to guarantee those factors, so one usually uses exceptions: from shutil import move try: move('somefile.txt', '/tmp/somefile.txt') except: print 'Move failed for some reason.' I'd like to actually catch the appropriate exceptions thrown instead of just catching everything, but I simply can't find a list of exceptions thrown for most python modules. Is there a way for me to see which exceptions a given function can throw, and why? This way I can make appropriate cases for each exception, eg: from shutil import move try: move('somefile.txt', '/tmp/somefile.txt') except PermissionDenied: print 'No permission.' except DestinationDoesNotExist: print "/tmp/ doesn't exist" except NoDiskSpace: print 'No diskspace available.' Answer points go to whoever can either link me to some relevant documentation that I've somehow overlooked in the official docs, or provide a sure-fire way to figure out exactly which exceptions are thrown by which functions, and why. Thanks!

  • How do I call an Obj-C method from Javascript?

    - by gnfti
    Hi all, I'm developing a native iPhone app using Phonegap, so everything is done in HTML and JS. I am using the Flurry SDK for analytics and want to use the [FlurryAPI logEvent:@"EVENT_NAME"]; method to track events. Is there a way to do this in Javascript? So when tracking a link I would imagine using something like <a onClick="flurryTrackEvent("Click_Rainbows")" href="#Rainbows">Rainbows</a> <a onClick="flurryTrackEvent("Click_Unicorns")" href="#Unicorns">Unicorns</a> "FlurryAPI.h" has the following: @interface FlurryAPI : NSObject { } + (void)startSession:(NSString *)apiKey; + (void)logEvent:(NSString *)eventName; + (void)logEvent:(NSString *)eventName withParameters:(NSDictionary *)parameters; + (void)logError:(NSString *)errorID message:(NSString *)message exception:(NSException *)exception; + (void)setUserID:(NSString *)userID; + (void)setEventLoggingEnabled:(BOOL)value; + (void)setServerURL:(NSString *)url; + (void)setSessionReportsOnCloseEnabled:(BOOL)sendSessionReportsOnClose; @end I'm only interested in the logEvent method(s). If it's not clear by now, I'm comfortable with JS but a recovering Obj-C noob. I've read the Apple docs but the examples described there are all for newly declared methods and I imagine this could be simpler to implement because the Obj-C method(s) are already defined. Thank you in advance for any input.

  • How could I cache images that I'm pulling from a magento database through ajax?

    - by wes
    Here's script being called through ajax: <?php require_once '../app/Mage.php'; umask(0); /* not Mage::run(); */ Mage::app('default'); $cat_id = ($_POST['cat_id']) ? $_POST['cat_id'] : NULL; try { $category = new Mage_Catalog_Model_Category(); $category->load($cat_id); $collection = $category->getProductCollection(); $output = '<ul>'; foreach ($collection as $product) { $cProduct = Mage::getModel('catalog/product'); $cProduct->load($product->getId()); $output .= '<li><img id="'.$product->getId().'" src="' . (string)Mage::helper('catalog/image')->init($cProduct, 'small_image')->resize(75) . '" class="thumb" /></li>'; } $output .= '</ul>'; echo $output; } catch (Exception $e) { echo 'Caught exception: ', $e->getMessage(), "\n"; } I'm just passing in the Category ID, which I've tacked onto the navigation links, then doing some work to eventually just pass back all product images in that category. I'm using this on a drag and drop build-a-bracelet type of application, and the amount of images returned is sometimes in the 500s. So it get's pretty held up during transmission, sometimes 10 seconds or so. I know I'd do good by caching them some way, just not sure how to go about it. Any help is much appreciated. Thanks. -Wes

  • Java: Help constructing a fillTextFields() method

    - by Holly
    I have a Java project where I am to connect to a database and create buttons (next, new, save, delete, previous) to navigate through the database content where there are appropriate text fields and labels for the specific information. I'll use the code below as an example (each button is set up very similar)... I have it as follows: JButton jbtnNext = new JButton("Next ->"); jbtnNext.addActionListener(this); if (e.getSource() == jbtnNext) jbtnNext_Click(); private void jbtnNext_Click() { JOptionPane.showMessageDialog(null, "Next" ,"Button Pressed", JOptionPane.INFORMATION_MESSAGE); try { if (rset.next()) { fillTextFields(true); }else{ //Display result in a dialog box JOptionPane.showMessageDialog(null, "Not found"); } } catch (SQLException ex) { ex.printStackTrace(); } } The professor gave the following outline of logic to construct the fillTextFields() method: Construct the method to provide reusable code that would fill the JTextFields on the GUI with appropriate values from current record from the database (when "Previous or "Next" buttons are pressed) or blank values (when the new Button is pressed). To determine when the current record was to provide values (next and previous) or the value would be blank (new button) pass a boolean argument into the method. If data from the current record was to be used as fill values, pass true for both previous and next button code after moving the record pointer. If the new button was pressed and want to fill with blank values, pass false to the method. Inside the method, use a conditional expression to evaluate the boolean variable. If true, The appropriate get----() resultset method is used to fill the JTextFields. If false, fill them with "". The .setText() method of the JTextField is used to fill each JTextField. Make sure the fillTextFields method throws the appropriate exception. I understand and have the previous and next button methods passing true, while the new button method is passing false, but I don't quite understand how to set up the fillTextFields() method correctly or how to "throw the appropriate exception"... Any help would really be appreciated, thank you!

  • How to get rid of exceptions thrown by the .NET Framework

    - by Hans Løken
    In a recent project I'm using a lot of databinding and xml-serialization. I'm using C#/VS2008 and have downloaded symbol information for the .NET framework to help me when debugging. The app I'm working on has a global "catch all" exception handler to present a more presentable messages to users if there happens to be any uncaught exceptions being thrown. My problem is when I turn on Exceptions-Thrown to be able to debug exceptions before they are caught by the "catch all". It seems to me that the framework throws a lot of exceptions that are not immediately caught (for example in ReflectPropertyDescriptor) so that the exception I'm actually trying to debug gets lost in the noise. Is there any way to get rid of exceptions caused by the framework but keep the ones from my own code? Update: after more research and actually trying to get rid of the exceptions that get thrown by the framework (many which turn out to be known issues in the framework, example: http://stackoverflow.com/questions/1127431/xmlserializer-giving-filenotfoundexception-at-constructor) I finally found a solution that works for me, which is turning on "Just my code" in Tools Options Debugging General Enable Just My Code in VS2008.

  • Programmatically filtering contacts in Outlook 2010 Add-In

    - by Leon Havin
    I am trying to programmatically filter Outlook contacts in the Contacts folder in Outlook 2010. I followed DASL filter rules, but it seems working for Find function and throws exception when I assign this filter to view.Filter = FilterString. Any ideas what I am doing wrong? The correct result would display filtered contacts in the existing contacts view. Outlook.Application myApp = ThisAddIn.myApp; Outlook.NameSpace myNamespace = ThisAddIn.nSpace; Outlook.MAPIFolder myContactsFolder = ThisAddIn.contactsFolder; if (myContactsFolder == null) { Log.Verbose("Contacts folder not found"); return null; } Outlook.Items contactItems = ThisAddIn.contactItems; //use filter to take only contact and not DistListItem Outlook.Items outlookContacts = contactItems.Restrict("[MessageClass] = 'IPM.Contact'"); Outlook.ContactItem contact = null; int iOutlookContacts = contactItems.Count; if (iOutlookContacts > 0) { string FilterString = "[FullName]='" + param + "'"; // Find works with this filter contact = (Outlook.ContactItem)outlookContacts.Find(FilterString); if (contact != null) { // need to display in contacts search window Outlook.View currentView = myApp.ActiveExplorer().CurrentView; currentView.Filter = FilterString; // cannot parse exception occurs here currentView.Save(); currentView.Apply(); } }

  • Insert or Update using Oracle and PL/SQL

    - by Shane
    I have a PL/SQL function that performs an update/insert on an Oracle database that maintains a target total and returns the difference between the existing value and the new value. Here is the code I have so far: FUNCTION calcTargetTotal(accountId varchar2, newTotal numeric ) RETURN number is oldTotal numeric(20,6); difference numeric(20,6); begin difference := 0; begin select value into oldTotal from target_total WHERE account_id = accountId for update of value; if (oldTotal != newTotal) then update target_total set value = newTotal WHERE account_id = accountId difference := newTotal - oldTotal; end if; exception when NO_DATA_FOUND then begin difference := newTotal; insert into target_total ( account_id, value ) values ( accountId, newTotal ); -- sometimes a race condition occurs and this stmt fails -- in those cases try to update again exception when DUP_VAL_ON_INDEX then begin difference := 0; select value into oldTotal from target_total WHERE account_id = accountId for update of value; if (oldTotal != newTotal) then update target_total set value = newTotal WHERE account_id = accountId difference := newTotal - oldTotal; end if; end; end; end; return difference end calcTargetTotal; This works as expected in unit tests with multiple threads never failing. However when loaded on a live system we have seen this fail with a stack trace looking like this: ORA-01403: no data found ORA-00001: unique constraint () violated ORA-01403: no data found The line numbers (which I have removed since they are meaningless out of context) verify that the first update fails due to no data, the insert fail due to uniqueness, and the 2nd update is failing with no data, which should be impossible. From what I have read on other thread a MERGE statement is also not atomic and could suffer similar problems. Does anyone have any ideas how to prevent this from occurring?

  • Pass in a value into Python Class through command line

    Hello, I have got some code to pass in a variable into a script from the command line. The script is: import sys, os def function(var): print var class function_call(object): def __init__(self, sysArgs): try: self.function = None self.args = [] self.modulePath = sysArgs[0] self.moduleDir, tail = os.path.split(self.modulePath) self.moduleName, ext = os.path.splitext(tail) __import__(self.moduleName) self.module = sys.modules[self.moduleName] if len(sysArgs) > 1: self.functionName = sysArgs[1] self.function = self.module.__dict__[self.functionName] self.args = sysArgs[2:] except Exception, e: sys.stderr.write("%s %s\n" % ("PythonCall#__init__", e)) def execute(self): try: if self.function: self.function(*self.args) except Exception, e: sys.stderr.write("%s %s\n" % ("PythonCall#execute", e)) if __name__=="__main__": test = test() function_call(sys.argv).execute() This works by entering ./function <function> <arg1 arg2 ....>. The problem is that I want to to select the function I want that is in a class rather than just a function by itself. The code I have tried is the same except that function(var): is in a class. I was hoping for some ideas on how to modify my function_call class to accept this. Thanks for any help.

  • Windows Phone - failing to get a string from a website with login information

    - by jumantyn
    I am new to accessing web services with Windows Phone 7/8. I'm using a WebClient to get a string from a php-website. The site returns a JSON string but at the moment I'm just trying to put it into a TextBox as a normal string just to test if the connection works. The php-page requires an authentication and I think that's where my code is failing. Here's my code: WebClient client = new WebClient(); client.Credentials = new NetworkCredential("myUsername", "myPassword"); client.DownloadStringCompleted += new DownloadStringCompletedEventHandler(client_DownloadStringCompleted); client.DownloadStringAsync(new Uri("https://www.mywebsite.com/ba/php/jsonstuff.php")); void client_DownloadStringCompleted(object sender, DownloadStringCompletedEventArgs e) { try { string data = e.Result; this.jsonText.Text = data; } catch (Exception ex) { System.Diagnostics.Debug.WriteLine(ex.Message); } } This returns first a WebException and then a TargetInvocationException. If I replace the Uri with for example "http://www.google.com/index.html" the jsonText TextBox gets filled with html text from Google (oddly enough, this also works even when the WebClient credentials are still set). So is the problem in the setting of the credentials? I couldn't find any good results when searching for guides on how to access php-pages with credentials, only without them. Then I found a short mention somewhere to use the WebClient.Credentials property. But should it work some other way? Update: here's what I can get out of the WebException (sorry for the bad formatting): System.Net.WebException: The remote server returned an error: NotFound. ---System.Net.WebException: The remote server returned an error: NotFound. at System.Net.Browser.ClientHttpWebRequest.InternalEndGetResponse(IAsyncResult asyncResult) at System.Net.Browser.ClientHttpWebRequest.<c_DisplayClasse.b_d(Object sendState) at System.Net.Browser.AsyncHelper.<c_DisplayClass1.b_0(Object sendState) --- End of inner exception stack trace --- at System.Net.Browser.AsyncHelper.BeginOnUI(SendOrPostCallback beginMethod, Object state) at System.Net.Browser.ClientHttpWebRequest.EndGetResponse(IAsyncResult asyncResult) at System.Net.WebClient.GetWebResponse(WebRequest request, IAsyncResult result) at System.Net.WebClient.DownloadBitsResponseCallback(IAsyncResult result)

  • Repaint() not calling paint() in Java

    - by Joshua Auriemma
    Let me start off by saying I know I've violated some basic Java principles in this messy code, but I'm desperately trying to finish a program by Tuesday for a social science experiment, and I don't know Java, so I'm basically just fumbling through it for now. With that disclaimer out of the way, I have a separate program working where a circle is moving around the screen and the user must click on it. It works fine when its in its own separate class file, but when I add the code to my main program, it's no longer working. I don't even really understand why repaint() calls my paint() function — as far as I'm concerned, it's magic, but I've noticed that repaint() calls paint() in my test program, but not in the more complicated actual program, and I assume that's why the circle is no longer painting on my program. Entire code is below: import java.awt.Color; import java.awt.Graphics; import java.awt.Graphics2D; import java.awt.Rectangle; import javax.swing.*; import java.awt.event.*; import java.awt.geom.Ellipse2D; import java.io.FileReader; import java.io.IOException; import java.util.Calendar; public class Reflexology1 extends JFrame{ private static final long serialVersionUID = -1295261024563143679L; private Ellipse2D ball = new Ellipse2D.Double(0, 0, 25, 25); private Timer moveBallTimer; int _ballXpos, _ballYpos; JButton button1, button2; JButton movingButton; JTextArea textArea1; int buttonAClicked, buttonDClicked; private long _openTime = 0; private long _closeTime = 0; JPanel thePanel = new JPanel(); JPanel thePlacebo = new JPanel(); final JFrame frame = new JFrame("Reflexology"); final JFrame frame2 = new JFrame("The Test"); JLabel label1 = new JLabel("Press X and then click the moving dot as fast as you can."); public static void main(String[] args){ new Reflexology1(); } public Reflexology1(){ frame.setSize(600, 475); frame.setLocationRelativeTo(null); frame.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE); frame.setTitle("Reflexology 1.0"); frame.setResizable(false); frame2.setSize(600, 475); frame2.setLocationRelativeTo(null); frame2.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE); frame2.setTitle("Reflexology 1.0"); frame2.setResizable(false); button1 = new JButton("Accept"); button2 = new JButton("Decline"); //movingButton = new JButton("Click Me"); ListenForAcceptButton lForAButton = new ListenForAcceptButton(); ListenForDeclineButton lForDButton = new ListenForDeclineButton(); button1.addActionListener(lForAButton); button2.addActionListener(lForDButton); //movingButton.addActionListener(lForMButton); JTextArea textArea1 = new JTextArea(24, 50); textArea1.setText("Tracking Events\n"); textArea1.setLineWrap(true); textArea1.setWrapStyleWord(true); textArea1.setSize(15, 50); textArea1.setEditable(false); FileReader reader = null; try { reader = new FileReader("EULA.txt"); textArea1.read(reader, "EULA.txt"); } catch (IOException exception) { System.err.println("Problem loading file"); exception.printStackTrace(); } finally { if (reader != null) { try { reader.close(); } catch (IOException exception) { System.err.println("Error closing reader"); exception.printStackTrace(); } } } JScrollPane scrollBar1 = new JScrollPane(textArea1, JScrollPane.VERTICAL_SCROLLBAR_AS_NEEDED, JScrollPane.HORIZONTAL_SCROLLBAR_NEVER); AdjustmentListener listener = new MyAdjustmentListener(); thePanel.add(scrollBar1); thePanel.add(button1); thePanel.add(button2); frame.add(thePanel); ListenForMouse lForMouse = new ListenForMouse(); thePlacebo.addMouseListener(lForMouse); thePlacebo.add(label1); frame2.add(thePlacebo); ListenForWindow lForWindow = new ListenForWindow(); frame.addWindowListener(lForWindow); frame2.addKeyListener(new KeyAdapter() { public void keyPressed(KeyEvent e){ if(e.getKeyChar() == 'X' || e.getKeyChar() == 'x') {moveBallTimer.start();} } }); frame.setVisible(true); moveBallTimer = new Timer(1000, new ActionListener() { public void actionPerformed(ActionEvent e) { moveBall(); System.out.println("Timer started!"); repaint(); } }); addKeyListener(new KeyAdapter() { public void keyPressed(KeyEvent e) { if(frame2.isVisible()){ moveBallTimer.start(); } } }); } private class ListenForAcceptButton implements ActionListener{ public void actionPerformed(ActionEvent e){ if (e.getSource() == button1){ Calendar ClCDateTime = Calendar.getInstance(); System.out.println(ClCDateTime.getTimeInMillis() - _openTime); _closeTime = ClCDateTime.getTimeInMillis() - _openTime; //frame.getContentPane().remove(thePanel); //thePlacebo.addKeyListener(lForKeys); //frame.getContentPane().add(thePlacebo); //frame.repaint(); //moveBallTimer.start(); frame.setVisible(false); frame2.setVisible(true); frame2.revalidate(); frame2.repaint(); } } } private class ListenForDeclineButton implements ActionListener{ public void actionPerformed(ActionEvent e){ if (e.getSource() == button2){ JOptionPane.showMessageDialog(Reflexology1.this, "You've declined the license agreement.

I'm assuming the multiple frames is causing the problem, but that's just a guess. Thanks.

  • When using a repository is it possible for a type to return a Func that the repository uses to test for existing entities?

    - by Scott Rickman
    For example given a Factory with a method public static T Save<T>(T item) where T : Base, new() { /* item.Id == Guid.Empty therefore item is new */ if (item.Id == Guid.Empty && repository.GetAll<T>(t => t.Name == item.Name)) { throw new Exception("Name is not unique"); } } how do I create a property of Base (say MustNotAlreadyExist) so that I can change the method above to public static T Save<T>(T item) where T : Base, new() { /* item.Id == Guid.Empty therefore item is new */ if (item.Id == Guid.Empty && repository.GetAll<T>(t.MustNotAlreadyExist)) { throw new Exception("Name is not unique"); } } public class Base { ... public virtual Expression<Func<T, bool>> MustNotAlreadyExist() { return (b => b.Name == name); /* <- this clearly doesn't work */ } } and then how can I override MustNotAlreadyExist in Account : Base public class Account : Base { ... public override Expression<Func<T, bool>> MustNotAlreadyExist() { return (b => b.Name == name && b.AccountCode == accountCode); /* <- this doesn't work */ } ... }

  • Mimic Coldfusion's debug output in PHP?

    - by TekiusFanatikus
    I'm trying to mimic Coldfusion's debug output in PHP. Here's an example of what it looks like (ie. Execution Time section): I've turned to XDebug. Ideally, the exception stack error output would be what I'd be looking for. However, it only shows up when an exception occurs. I also tried something like (in our CMS-ish app) this (original question here): $content.= "<?php xdebug_start_trace('e:/xdebug/trace');?>"; $content.= "<?php require('".$page['file_'.LG]."'); ?>"; $content.= "<?php xdebug_stop_trace();?>"; ... $content.= "<?php echo readfile('e:/xdebug/trace.xt');?>"; However, I get an insane, browser crashing HTML table dropped at the bottom of page. Not very efficient. My php.ini config: xdebug.trace_format = 2 xdebug.collect_vars = 1 xdebug.collect_params = 4 xdebug.dump_globals = 1 xdebug.dump.SERVER = 'REQUEST_URI' xdebug.show_local_vars = 1 xdebug.show_mem_delta = 1 I'm just wondering if someone has already done something similar?

  • What should the name of this class be?

    - by Tim Murphy
    Naming classes is sometimes hard. What do you think name of the class should be? I originally created the class to use as a cache but can see its may have other uses. Example code to use the class. Dim cache = New NamePendingDictionary(Of String, Sample) Dim value = cache("a", Function() New Sample()) And here is the class that needs a name. ''' <summary> ''' Enhancement of <see cref="System.Collections.Generic.Dictionary"/>. See the Item property ''' for more details.

  • Connect to Facebook with Javascript Client Library using Adobe AIR

    - by Chuck Hriczko
    I'm having an issue connecting to Facebook through the Javascript Client Library in Adobe AIR. It works fine in the browser but in Adobe AIR it seems to not be able to find the Facebook functions. Here is some code I copied from the Facebook website: (Oh and I have the xd_receiver.htm file in the correct path too) <textarea style="width: 1000px; height: 300px;" id="_traceTextBox"> </textarea> <script src="http://static.ak.connect.facebook.com/js/api_lib/v0.4/FeatureLoader.js.php" type="text/javascript"></script> // var api = FB.Facebook.apiClient; // require user to login api.requireLogin(function(exception){ FB.FBDebug.logLevel=1; FB.FBDebug.dump("Current user id is " + api.get_session().uid); // Get friends list //5-14-09: this code below is broken, correct code follows //api.friends_get(null, function(result){ // Debug.dump(result, 'friendsResult from non-batch execution '); // }); api.friends_get(new Array(), function(result, exception){ FB.FBDebug.dump(result, 'friendsResult from non-batch execution '); }); }); }); //]]> </script>

  • PendingIntent sent from a notication.

    - by totem
    Hi, What im trying to accomplish is to send a notification through the notification manager that once clicked will do something in the application only if its currently running. i have tried to use: notification.contentIntent = PendingIntent.getActivity(this, nNotificationCounter, Someintent, PendingIntent.FLAG_NO_CREATE) Which allways caused an exception once trying to use the notify. I switched to: Notification notification = new Notification(icon, tickerText, when); RemoteViews contentView = new RemoteViews(getPackageName(), R.layout.some_notification); contentView.setTextViewText(R.id.title, sTitle); contentView.setTextViewText(R.id.text, sText); notification.contentView = contentView; notification.defaults |= Notification.DEFAULT_SOUND; notification.number = nNotificationCounter; Intent notificationIntent = new Intent(this, MainWindow.class).setAction(ACTION_RESET_MESSGE_COUNTER); notification.contentIntent = PendingIntent.getBroadcast(this, nNotificationCounter, notificationIntent, 0); and although this code doesn't cause an exception. it doesnt call my BroadcastReceiver which is defined as follows: public class IncomingReceiver extends BroadcastReceiver { @Override public void onReceive(Context context, Intent intent) { if (intent.getAction().equals(ACTION_RESET_MESSGE_COUNTER)) { System.out.println("GOT THE INTENT"); return; } } } and set in the onCreate: IntentFilter filter = new IntentFilter(ACTION_RESET_MESSGE_COUNTER); IncomingReceiver receiver = new IncomingReceiver(); context.registerReceiver(receiver, filter); Does anyone see something wrong with the code? Or how would i go about to get messages when the notification is clicked, but not create any activity if it isn't already created. edit: added the intent creation and notification creation. Thanks, Tom

  • delegate method throws runtime "unrecognized selector" error when switching back from one UIViewCont

    - by chimgrrl
    Ok, I've spend like half day on this and it's killing me. So I've got 3 view controllers transitioning from one another, something like this: I call the UploadDecisionViewController after destroying the previous View Controller: [self dismissModalViewControllerAnimated:YES]; [self performSelector:@selector(showUDModalView) withObject:nil afterDelay:0.5]; In my showUDModalView method: - (void)showUDModalView { UploadDecisionViewController *udcontroller = [[UploadDecisionViewController alloc] initWithNibName:@"UploadDecisionViewController" bundle:nil]; udcontroller.delegate = self; [self presentModalViewController:udcontroller animated:YES]; [udcontroller release]; } The UploadDecisionViewController shows up no problem. The UploadDecisionViewController has a button, which when clicked I want it to transition to the FileUploadViewController. I setup a UploadDecisionDelegate, threw a method in there to handle the button clicking: Inside UploadDecisionDelegate protocol (UploadDecisionViewController.h): @protocol UploadDecisionDelegate //let UOnliveViewController know that a button was selected - (void)UploadDecisionViewController:(UploadDecisionViewController *)controller madeChoice:(NSString *)whichDirection; @end Then inside my IBAction method when the button is clicked, I have this: - (IBAction)decisionSelected:(id)sender { [delegate UploadDecisionViewController:self madeChoice:@"upload"];//crashing at this line } When I run this, at this line above it is throwing a runtime exception: 2010-06-09 12:48:59.561 UOnlive[4735:207] *** -[UIView UploadDecisionViewController:madeChoice:]: unrecognized selector sent to instance 0x3b65420 2010-06-09 12:48:59.562 UOnlive[4735:207] *** Terminating app due to uncaught exception 'NSInvalidArgumentException', reason: '*** -[UIView UploadDecisionViewController:madeChoice:]: unrecognized selector sent to instance 0x3b65420' 2010-06-09 12:48:59.563 UOnlive[4735:207] Stack: ( 33502299, 2495698185, 33884219, 33453686, 33306306, 20618, 2982917, 3390286, 3399023, 3394235, 3087839, 2996168, 3022945, 40156505, 33287040, 33283144, 40150549, 40150746, 3026863, 11700, 11554 ) Let me throw in the delegate method implemented also: - (void)UploadDecisionViewController:(UploadDecisionViewController *)controller madeChoice:(NSString *)whichDirection { NSLog(@"it got to here 245"); [self dismissModalViewControllerAnimated:YES]; if (yesOrNo) { //open up the FileUploadViewController and proceed to upload [self performSelector:@selector(showFUModalView) withObject:nil afterDelay:0.5]; } } Can someone tell me what the heck is going on? Thanks a bunch for the help...
