• Can't find compiled resource bundles

  - by user351032

  I am using Adobe Flash Builder 4. I've run into this issue with my latest project, but I was able to re-create it with an almost empty project. Here is what I've done. Created a new Flex Project Created a locale/en_US folder within this project. Added a class that extends SparkDownloadProgressBar. All this class does is attempt to create a Label. When I try to debug this application, I get the following error. Error: Could not find compiled resource bundle 'components' for locale 'en_US'. at mx.resources::ResourceManagerImpl/installCompiledResourceBundle()[E:\dev\4.0.0\frameworks\projects\framework\src\mx\resources\ResourceManagerImpl.as:340] at mx.resources::ResourceManagerImpl/installCompiledResourceBundles()[E:\dev\4.0.0\frameworks\projects\framework\src\mx\resources\ResourceManagerImpl.as:269] at mx.resources::ResourceManagerImpl/processInfo()[E:\dev\4.0.0\frameworks\projects\framework\src\mx\resources\ResourceManagerImpl.as:387] at mx.resources::ResourceManagerImpl()[E:\dev\4.0.0\frameworks\projects\framework\src\mx\resources\ResourceManagerImpl.as:122] at mx.resources::ResourceManager$/getInstance()[E:\dev\4.0.0\frameworks\projects\framework\src\mx\resources\ResourceManager.as:111] at mx.core::UIComponent()[E:\dev\4.0.0\frameworks\projects\framework\src\mx\core\UIComponent.as:3728] at spark.components.supportClasses::TextBase()[E:\dev\4.0.0\frameworks\projects\spark\src\spark\components\supportClasses\TextBase.as:154] at spark.components::Label()[E:\dev\4.0.0\frameworks\projects\spark\src\spark\components\Label.as:384] at Preloader()[C:\SVN\Games\Social\Test\src\Preloader.as:21] at mx.preloaders::Preloader/initialize()[E:\dev\4.0.0\frameworks\projects\framework\src\mx\preloaders\Preloader.as:253] at mx.managers::SystemManager/http://www.adobe.com/2006/flex/mx/internal::initialize()[E:\dev\4.0.0\frameworks\projects\framework\src\mx\managers\SystemManager.as:1925] at mx.managers::SystemManager/initHandler()[E:\dev\4.0.0\frameworks\projects\framework\src\mx\managers\SystemManager.as:2419] The Flex Compiler/Additional Compiler Arguments section does contain "-locale en_US", but I do not want to just remove this as I am planning to have this load different property files based on the localization region at run-time and how I understand it, I will need to add each locale that I am planning to use on the compile argument line. I am at a loss as to how to attack this problem. If you need anymore information from me to help with this, I will be more than happy to provide it. Thanks ahead of time for the help!

• FreeRTOS Sleep Mode hazards while using MSP430f5438

  - by michael

  Hi, I wrote an an idle hook shown here void vApplicationIdleHook( void ) { asm("nop"); P1OUT &= ~0x01;//go to sleep lights off! LPM3;// LPM Mode - remove to make debug a little easier... asm("nop"); } That should cause the LED to turn off, and MSP430 to go to sleep when there is nothing to do. I turn the LED on during some tasks. I also made sure to modify the sleep mode bit in the SR upon exit of any interrupt that could possibly wake the MCU (with the exception of the scheduler tick isr in portext.s43. The macro in iar is __bic_SR_register_on_exit(LPM3_bits); // Exit Interrupt as active CPU However, it seems as though putting the MCU to sleep causes some irregular behavior. The led stays on always, although when i scope it, it will turn off for a couple instructions cycles when ever i wake the mcu via one of the interrupts (UART), and then turn back on. If I comment out the LPM3 instruction, things go as planned. The led stays off for most of the time and only comes on when a task is running. I am using a MSP4f305438 Any ideas?

• Fail to load NPAPI plugin in Google Chrome on Mac OS X

  - by Roman

  I have been trying to get Google Chrome (6.0.401.1 dev) on Mac OS X to load an NPAPI plugin without success so far. I have been working around the npsimple example from here: http://git.webvm.net/?p=npsimple. Using gcc on Mac and VC++ 2008 on Windows I managed to get it running on Safari and Firefox on Mac OS X and Firefox and Google Chrome on Windows, but not on Google Chrome on Mac OS X. When trying to debug Google Chrome on Mac OS X it seemed Google Chrome was briefly dyld-loading (and immediately dyld-unloading) the plugin on startup, but without actually looking-up any symbols within the plugin or calling any of the functions. It seemed to be doing that for every plugin, though. Also, when loading a page with the embed-tag for the plugin, Google Chrome did not seem to even dyld-load the plugin and no functions were called (not even NP_GetEntryPoints). Google Chrome also does not output any error message, it just simply does not load the plugin. I am not sure I caught everything with gdb because of Google Chrome using different processes, but I have also tried all the switches like --no-sandbox, --single-process and --plugin-startup-dialog (which incidentally does not seem to work at all on Mac OS X). I also made sure the architecture of the binary matches (i.e. 32-bit for Google Chrome). Has anybody had similar problems before? Is there anything I am missing here, like a gcc switch when compiling or something? Any help would be greatly appreciated.

• Kill a node in dojo.dnd.source ?

  - by Soulhuntre

  Related to my SO issue at http://stackoverflow.com/questions/3010996/dojo-extending-dojo-dnd-source-move-not-happening-ideas/3012518#3012518 I am now almost done. I have a dnd.Source derived class - we can consider it a dnd.Source for now, that has within it a node that has a specific class. function declare_mockupSmartDndUl(){ dojo.require("dojo.dnd.Source"); dojo.provide("mockup.SmartDndUl"); dojo.declare("mockup.SmartDndUl", dojo.dnd.Source, { markupFactory: function(params, node){ //params._skipStartup = true; return new mockup.SmartDndUl(node, params); }, onDropExternal: function(source, nodes, copy){ console.debug('onDropExternal called...'); // dojo.destroy(this.getAllNodes().query(".dndInstructions")); this.inherited(arguments); var x = source.getAllNodes().length; if( x == 0 ){ newnode = document.createElement('li'); newnode.innerHTML = "Hello!"; dojo.addClass(newnode,"dndInstructions"); source.node.appendChild(newnode); } return true; // return dojo.dnd.Source.prototype.onDropExternal.call(this, source, nodes, copy); } }); } You can see the place I mean from the dojo.destroy that is commented out because it was totally n00b :) If I do this var y = this.getAllNodes().query(".dndInstructions") the nodelist in y absolutely does contain the node. Now I need t kill it, nuke it - get it out of there. Out of the dnd.Source, out of the DOM... gone. Any ideas how to do it safely? It will be the ONLY node in the list at the time we do whatever it is we are goign to do to kill the thing. Thanks!

• Setting custom behaviour via .config file - why doesn't this work?

  - by Andrew Shepherd

  I am attempting to insert a custom behavior into my service client, following the example here. I appear to be following all of the steps, but I am getting a ConfigurationErrorsException. Is there anyone more experienced than me who can spot what I'm doing wrong? Here is the entire app.config file. <?xml version="1.0" encoding="utf-8" ?> <configuration> <system.serviceModel> <behaviors> <endpointBehaviors> <behavior name="ClientLoggingEndpointBehaviour"> <myLoggerExtension /> </behavior> </endpointBehaviors> </behaviors> <extensions> <behaviorExtensions> <add name="myLoggerExtension" type="ChatClient.ClientLoggingEndpointBehaviourExtension, ChatClient, Version=0.0.0.0, Culture=neutral, PublicKeyToken=null"/> </behaviorExtensions> </extensions> <bindings> </bindings> <client> <endpoint behaviorConfiguration="ClientLoggingEndpointBehaviour" name="ChatRoomClientEndpoint" address="http://localhost:8016/ChatRoom" binding="wsDualHttpBinding" contract="ChatRoomLib.IChatRoom" /> </client> </system.serviceModel> </configuration> Here is the exception message: An error occurred creating the configuration section handler for system.serviceModel/behaviors: Extension element 'myLoggerExtension' cannot be added to this element.

• 'Hot code replace' not working -- Eclipse doesn't change any code on JBoss

  - by Bernhard V

  Hello, fellow visitors! I'm currently experiencing a problem with 'hot code replace' not working on Eclipse Galileo and JBoss 4.2.3. Among other applications I'm running an exploded Java WAR on my local JBoss. The project from which it is build is managed by Maven. I build the project using the Maven goal war:exploded and then I copy that directory to JBoss with an ANT script. When I'm now running the application and set a breakpoint anywhere in the code, Eclipse properly halts at that line in the debug mode. But when I'm making a change to the source file and save it, Eclipse doesn't apply this change to the JBoss. For example, when I make a normal code line into a comment, the debugger still steps over this comment as if it was regular Java code. Or when I remove a line, the debugger seems to get out of sync with the file and starts stepping over parenthesis. But I'm not getting any 'hot code replace error'-messages either. It seems to me that Eclipse applies the changes to the source files, but doesn't apply it to the JBoss. Are there any special preferences that have to be turned on in order to make hot code replace work? Or are there any mistakes in how I build and deploy the application to the JBoss? I'd appreciate your help very much. Thank you. Bernhard V

• Import Excel 2007 into SQL 2000 using Classic ASP and ADO

  - by jeff

  I have the following code from a legacy app which currently reads from an excel 2003 spreadsheet on a server, but I need this to run from my machine which uses excel 2007. When I debug on my machine ADO does not seem to be reading the spreadsheet. I have checked all file paths etc. and location of spreadsheet that is all fine. I've heard that you cannot use the jet db engine for excel 2007 anymore? Can someone confirm this? What do I need to do to get this to work?

• Encrypt/Decrypt ECB/PKS5/Blowfish between AS3Crypto & Javax.Crypto fails with padding error

  - by BlueDude

  I have a secret key that was sent to me as a file so I can encrypt some xml data using Blowfish. How do I access the key so that I can use it with AS3Crypto? I assume I need to Embed it using the [Embed] meta tag. It's mimeType="application/octet-stream" but I'm not sure if thats right. How do I embed, then reference this file as the secret key? The xmls that I'm encrypting cannot be decrypted on the Java side. Each attempt fails with this exception: javax.crypto.BadPaddingException: Given final block not properly padded. As a bonus, if anyone has experience using the lib to work with the Java implementation and knows the ideal mode/padding/IV to use that would be awesome. Thanks! //keyFile is an embedded asset. I was given a file to use as the key var kdata:ByteArray = new keyFile() as ByteArray; //Convert orderXML to Base64 var orderData:ByteArray = Base64.decodeToByteArray(String(orderXML)); //Cipher name var cname:String = "simple-blowfish-ecb"; var pad:IPad = new PKCS5; var mode:ICipher = Crypto.getCipher(cname, kdata, pad); //not sure if this is necessary. seems to be also set in mode pad.setBlockSize(mode.getBlockSize()); mode.encrypt(orderData); var transmitXML:String = Base64.encodeByteArray(orderData); //DEBUG: Output to TextArea storePanel.statusBox.text += "\n--TRANSMIT--\n"+transmitXML;

• UIImagePickerController image editing not working

  - by Greg Reichow

  I am having a problem with implementing UIImagePickerController. When the controller loads, it displays modally, and allows the user to select the image. Good so far. Yet, then when it moves to the editing phase, it often displays somewhat corrupted view (the image cropping box is halfway off the top of the screen) and their is no image. It does not crash, but all UI interaction is blocked. The strange part is that this only happens when I compile with Release settings. Under debug compile settings, the image editing works fine! I have tried checking for memory warnings during this time, but none are showing up. Here is the code calling the image picker controller for reference. When I use the camera (the first method), it always works fine. It is just when selecting images from the Library (called from the second method below) does it fail as described above. And again, only on release build, and with various different types of images. - (IBAction) showCameraController:(id)sender { self.imagePicker =[[UIImagePickerController alloc] init]; self.imagePicker.sourceType=UIImagePickerControllerSourceTypeCamera; self.imagePicker.delegate=self; self.imagePicker.allowsEditing=YES; [self presentModalViewController:self.imagePicker animated:YES]; } - (IBAction) showPictureAlbumController:(id)sender { self.imagePicker =[[UIImagePickerController alloc] init]; self.imagePicker.sourceType=UIImagePickerControllerSourceTypePhotoLibrary; self.imagePicker.delegate=self; self.imagePicker.allowsEditing=YES; [self presentModalViewController:self.imagePicker animated:YES]; } The delegate methods are properly implemented, yet, during the problem I am describing, the controller is not yet calling those methods. It is failing when displaying the editing screen before the user is able to select cancel or save. It is just locking up with no crash. Please help!

• Web service SSL handshake fails in production environment unless SSL debugging enabled

  - by JST

  Scenario: calling a client web service over SSL (https) with mutual SSL authentication. Different service endpoint URLs and certs (both keystore and truststore) for test vs. production environments. Both test and production environments run tomcat / JBoss clustered. Production environment has load balancing / BigIP, runs Blade and non-Blade machines. Truststore is set (using -Djavax.net.ssl.trustStore=value) at startup. Keystore is set using System.setProperty("javax.net.ssl.keyStore", "value") in Java code. Web service call made using Axis2. All works fine in test environment, but when we moved to production environment (6 servers), it appears certs are not being forwarded for the handshake. Here's what we've done: in test environment, handshake using test versions of certs has been working all along, with no ssl debugging enabled confirmed in test environment that handshake with client production endpoint succeeds (production certs, both ours and theirs, are fine) -- this was done using -Djavax.net.debug=handshake,ssl confirmed that the error condition occurs on all 6 production servers took one server out of the cluster, turned on ssl debugging for just that one (with a restart), hit it directly, handshake works! switched to a different server without the debugging turned on, handshake error condition occurs turned debugging on on that second server (with a restart), hit it directly, handshake works! From the evidence, it seems like somehow the debugging being enabled causes the certificates to be properly retrieved/conveyed, although that makes no sense! I wonder whether somehow the enabled debugging makes the system pay attention to the System.setProperty call, and ignore it otherwise. However, in local and test environments, handshake worked without debugging enabled. Do I maybe need to be setting keystore on server startup like I'm setting truststore? Have been avoiding that because the keystore will differ for each of our test environments (16 of them).

• vbCrLf in Multiline TextBox shows up only when .Trim() is called

  - by Brandon Montgomery

  I have an ASP TextBox with TextMode set to MultiLine. I'm having problems with preserving the vbCrLf characters when a user tries to put line breaks into the text. When a button on the page is pressed, I'm taking the text from the control, trimming it using String.Trim, and assigning that value to a String property on an object (which, in turn assigns it to a private internal String variable on the object). The object then takes the value from the private internal variable and throws it into the database using a stored procedure call (the SP parameter it is put into is an nvarchar(4000)). ASPX Page: <asp:UpdatePanel ID="UpdatePanel2" runat="server" RenderMode="Inline" UpdateMode="Conditional" ChildrenAsTriggers="true"> <ContentTemplate> <!-- some other controls and things --> <asp:TextBox TextMode="MultiLine" runat="server" ID="txtComments" Width="100%" Height="60px" CssClass="TDTextArea" Style="border: 0px;" MaxLength="2000" /> <!-- some other controls and things --> </ContentTemplate> </asp:UpdatePanel> code behind: ProjectRequest.StatusComments = txtComments.Text.Trim object property: Protected mStatusComments As String = String.Empty Property StatusComments() As String Get Return mStatusComments.Trim End Get Set(ByVal Value As String) mStatusComments = Value End Set End Property stored proc call: Common.RunSP(mDBConnStr, "ProjectStatusUpdate", _ Common.MP("@UID", SqlDbType.NVarChar, 40, mUID), _ Common.MP("@ProjID", SqlDbType.VarChar, 40, mID), _ Common.MP("@StatusID", SqlDbType.Int, 8, mStatusID), _ Common.MP("@Comments", SqlDbType.NVarChar, 4000, mStatusComments), _ Common.MP("@PCTComp", SqlDbType.Int, 4, 0), _ Common.MP("@Type", Common.TDSqlDbType.TinyInt, 1, EntryType)) Here's the strangest part. When I debug the code, if I type "test test" (without the quotes) into the comments text box, then click the save button and use the immediate window to view the variable values as I step through, here is what I get: ?txtComments.Text "test test" ?txtComments.Text.Trim "test test" ?txtComments.Text(4) " "c ?txtComments.Text.Trim()(4) " "c Anyone have a clue as to what's going on here?

• Avoid PHP timeout when sending newsletter

  - by Lars

  Hi, I have recently implemented the Swiftmailer library, but the first time I used it, I got a php timeout error even though it only had to send out mails to around 300 people.. (I should mention that using the set_time_limit(0); workaround is not an option due to restrictions on the server) The way I use it is like this: $transport = Swift_SmtpTransport::newInstance('smtp.mydomain.com',25); $mailer = Swift_Mailer::newInstance($transport); $message = Swift_Message::newInstance(); $message->setSubject($_POST['subj']); $message->setFrom(array('email' => 'Mysite')); $message->setTo($recipients); $message->setBody(strip_tags($messagebody)); $message->addPart($messagebody, 'text/html'); $numSent = $mailer->batchSend($message); printf("Sent %d messages\n", $numSent); where $recipients is a commaseparated array of emails (built with explode() from a mySQL query).. I have no idea which part of the above code that generates the script-timeout, and since I use it for a newsletter function, it is rather difficult for me to test or debug it, so I would be really thankful for anyone coming up with a (near) bulletproof solution to this problem :) Thanks in advance !

• Debugger Visualizer, ElementHost, and Edit and Continue problems

  - by Frank Fella

  I recently wrote a custom Debugger Visualizer for Visual Studio 2008 for one of the custom types in my application. The UI for the visualizer is written in WPF and is hosted in an element host and shown using the IDialogVisualizerService windowService object. Everything works great, and my visualizer loads and shows the relevant information, but if try to "edit and continue" in my application after loading the visualizer, Visual Studio crashes with no useful error message. In trying to debug this I removed almost all of my code from the solution to the point where I was only serializing a string with the ObjectSource and displaying just an empty element host and I still get the crash on edit and continue. If I remove the element host and show a WinForms control or form there is no crash. Here is the Visualizer code: using System; using System.Drawing; using System.IO; using System.Runtime.Serialization.Formatters.Binary; using System.Windows.Forms; using System.Windows.Forms.Integration; using Microsoft.VisualStudio.DebuggerVisualizers; using ObjectVisualizerShared; using ObjectVisualizerUI; namespace ObjectVisualizer { public class Visualizer : DialogDebuggerVisualizer { protected override void Show(IDialogVisualizerService windowService, IVisualizerObjectProvider objectProvider) { try { Stream stream = objectProvider.GetData(); if (stream.Length > 0) { BinaryFormatter formatter = new BinaryFormatter(); VisualizerNode node = (VisualizerNode)formatter.Deserialize(stream); if (node != null) { VisualizerWindow window = new VisualizerWindow(node); ElementHost host = new ElementHost(); host.Child = window; host.Dock = DockStyle.Fill; host.Size = new Size(800, 600); windowService.ShowDialog(host); } } } catch (Exception ex) { MessageBox.Show(string.Format("Error!\n{0}", ex), "Object Visualizer"); } } } } Any ideas?

• C++: Explicit DLL Loading: First-chance Exception on non "extern C" functions

• SerializationException Occurring Only in Release Mode

  - by Calvin Nguyen

  Hi, I am working on an ASP.NET web app using Visual Studio 2008 and a third-party library. Things are fine in my development environment.

• NSFetchedResultsController not updating UITableView's section indexes

  - by Luther Baker

  I am populating a UITableViewController with an NSFetchedResultsController with results creating sections that populate section headers and a section index. I am using the following method to populate the section index: - (NSArray *)sectionIndexTitlesForTableView:(UITableView *)tableView { return [fetchedResultsController_ sectionIndexTitles]; } and now I've run into a problem. When I add a new element to the NSManagedObjectContext associated with the NSFetchedResultsController, the new element is saved and appropriately displayed as a cell in the UITableView ... except for one thing. If the new element creates a new SECTION, the new section index does not show up in the right hand margin unless I pop the UINavigationController's stack and reload the UITableViewController. I have conformed to the NSFetchedResultsControllerDelegate's interface and manually invoke [self.tableView reloadSectionIndexTitles]; at the end of both these delegate methods: controller:didChangeSection... controller:didChangeObject... and while I can debug and trace the execution into the methods and see the reload call invoked, the UITableView's section index never reflects the section changes. Again, the data shows up - new sections are physically visible (or removed) in the UITableView but the section indexes are not updated. Am I missing something?

• AppDomain.CurrentDomain.UnhandledException doesn't always fire up

  - by Simon T.

  I encountered an exception in our application that isn't handled at all. I really don't know what to look for to debug this problem since the application close immediately when this peculiar exception is thrown (even running from VS). The exception handling is setup that way: [STAThread] [LoaderOptimizationAttribute(LoaderOptimization.MultiDomainHost)] static void Main() { Application.SetUnhandledExceptionMode(UnhandledExceptionMode.CatchException); Application.ApplicationExit += new EventHandler(ApplicationExitHandler); Application.ThreadException += new ThreadExceptionEventHandler(ThreadExceptionHandler); AppDomain.CurrentDomain.UnhandledException += new UnhandledExceptionEventHandler(UnhandledExceptionHandler); ... The thread from which the exception is thrown is started that way: Thread executerThread = new Thread(new ThreadStart(modele.Exporter)); executerThread.SetApartmentState(ApartmentState.STA); executerThread.Start(); Now, every unhandled exception thrown from that thread fire up our UnhandledExceptionHandler except the one I have problems with. Even if I catch the problematic exception and throw it again, the application closes silently. None of the 3 handlers (ApplicationExit, ThreadException, UnhandledException) get fired (breakpoints not hit). There is nothing so exceptional in that exception (see details here: http://pastebin.com/fCnDRRiJ).

• Language+IDE for teaching high school students?

  - by daveagp

  I'm investigating languages and IDEs for a project involving teaching high-school students (around grade 11). It will teach basics of programming as an introduction to computer science (e.g., including how numbers/strings/characters are represented, using procedures and arrays, control flow, a little bit of algorithms, only very basic I/O). The non-negotiable requirements for this project are: a free up-to-date cross-platform IDE (Win & Mac incl. 64-bit) with debug a compiler where it's easy to learn from your mistakes together with the IDE, a gentle installation+learning curve So far, the best options I see are the following. Are there others I should know about? I am giving a short explanation with each one to generally show what I am looking for. In order from most to least promising: Pascal + FreePascal IDE (it seems a little buggy but actively developed?) Python + Eclipse + PyDev (good but features are overwhelming/hard to navigate) Groovy + Eclipse ('') Python + IDLE (looks unnatural to do debugging, to me) Pascal + Lazarus (IDE overwhelming, e.g. not obvious how to "start from scratch") Preferably, as a rule of thumb, the language should be direct enough that you don't need to wrap every program in a class, don't need to reference a System object to println, etc. I tried a little bit to see if there is something in JavaScript or (non-Visual) Basic along the lines of what I want, but found nothing so far. I would say that C/C++/C#, Java, Ruby, Lisp, VB do not fit my criteria for languages for this project. To reiterate my questions: are any of those 5 options really awesome or un-awesome? Are there other options which are even MORE awesome? Anything for Basic or JavaScript which meets all of the criteria? Thanks!

• Why is TransactionScope operation is not valid?

  - by Cragly

  I have a routine which uses a recursive loop to insert items into a SQL Server 2005 database The first call which initiates the loop is enclosed within a transaction using TransactionScope. When I first call ProcessItem the myItem data gets inserted into the database as expected. However when ProcessItem is called from either ProcessItemLinks or ProcessItemComments I get the following error. “The operation is not valid for the state of the transaction” I am running this in debug with VS 2008 on Windows 7 and have the MSDTC running to enable distributed transactions. The code below isn’t my production code but is set out exactly the same. The AddItemToDatabase is a method on a class I cannot modify and uses a standard ExecuteNonQuery() which creates a connection then closes and disposes once completed. I have looked at other posting on here and the internet and still cannot resolve this issue. Any help would be much appreciated. using (TransactionScope processItem = new TransactionScope()) { foreach (Item myItem in itemsList) { ProcessItem(myItem); } processItem.Complete(); } private void ProcessItem(Item myItem) { AddItemToDatabase(myItem); ProcessItemLinks(myItem); ProcessItemComments(myItem); } private void ProcessItemLinks(Item myItem) { foreach (Item link in myItem.Links) { ProcessItem(link); } } private void ProcessItemComments(Item myItem) { foreach (Item comment in myItem.Comments) { ProcessItem(comment); } } Here is top part of the stack trace. Unfortunatly I cant show the build up to this point as its company sensative information which I can not disclose. Hope this is enough information. at System.Transactions.TransactionState.EnlistPromotableSinglePhase(InternalTransaction tx, IPromotableSinglePhaseNotification promotableSinglePhaseNotification, Transaction atomicTransaction) at System.Transactions.Transaction.EnlistPromotableSinglePhase(IPromotableSinglePhaseNotification promotableSinglePhaseNotification) at System.Data.SqlClient.SqlInternalConnection.EnlistNonNull(Transaction tx) at System.Data.SqlClient.SqlInternalConnection.Enlist(Transaction tx) at System.Data.SqlClient.SqlInternalConnectionTds.Activate(Transaction transaction) at System.Data.ProviderBase.DbConnectionInternal.ActivateConnection(Transaction transaction) at System.Data.ProviderBase.DbConnectionPool.GetConnection(DbConnection owningObject) at System.Data.ProviderBase.DbConnectionFactory.GetConnection(DbConnection owningConnection) at System.Data.ProviderBase.DbConnectionClosed.OpenConnection(DbConnection outerConnection, DbConnectionFactory connectionFactory) at System.Data.SqlClient.SqlConnection.Open()

• How to connect to a SOAP webServices with Android

  - by dom4

  Hi everyone,I'm programming an application who must send coordinate and request to a WebServices this is my code: private String SOAP_ACTION = "getAllPositions"; private String METHOD_NAME = "getAllPositions"; private String NAMESPACE = "http://session/"; private static final String URL ="http://192.41.218.56:8080/WSGeoEAR-WSGeoServer/NavFinderBean?WSDL"; /** Called when the activity is first created. */ @Override public void onCreate(Bundle icicle) { super.onCreate(icicle); setContentView(R.layout.main); SoapObject request = new SoapObject(NAMESPACE, METHOD_NAME); request.addProperty("idUtente",1); SoapSerializationEnvelope envelope = new SoapSerializationEnvelope(SoapEnvelope.VER11); envelope.dotNet = true; envelope.setOutputSoapObject(request); AndroidHttpTransport androidHttpTransport = new AndroidHttpTransport(URL); androidHttpTransport.setXmlVersionTag("<?xml version=\"1.0\" encoding=\"UTF-8\"?>"); androidHttpTransport.debug = true; try{ androidHttpTransport.call(SOAP_ACTION, envelope); SoapObject resultsRequestSOAP = (SoapObject) envelope.bodyIn; ArrayList<position> resultData = (ArrayList<position>)resultsRequestSOAP.getProperty("getAllPositionsResponse"); for(position p : resultData) { ((TextView)findViewById(R.id.lblStatus)).setText(p.getAllInformation()); } } catch(Exception E) { ((TextView)findViewById(R.id.lblStatus)).setText("ERROR:" + E.getClass().getName() + ": " + E.getMessage()); } } } I've also create a class position. It doesn't work,can someone help me?Thanks

• ThreadAbortException (WebClient using DownloadFile to grab file from server)

  - by baron

  Hi Everyone, Referencing my Earlier Question, regarding downloading a file from a server and handling exceptions properly. I am positive that I had this solved, then in classic programming fashion, returned days later to frustratingly find it broken :-( Updated code: private static void GoGetIt(HttpContext context) { var directoryInfoOfWhereTheDirectoryFullOfFilesShouldBe = new FileInfo(......); var name = SomeBasicLogicToDecideName(); //if (!directoryInfoOfWhereTheDirectoryFullOfFilesShouldBe.RefreshExists()) //{ // throw new Exception(string.Format("Could not find {0}.", name)); //} var tempDirectory = ""; //Omitted - creates temporary directory try { directoryInfoOfWhereTheDirectoryFullOfFilesShouldBe.CopyAll(tempDirectory); var response = context.Response; response.ContentType = "binary/octet-stream"; response.AddHeader("Content-Disposition", string.Format("attachment;filename={0}.zip", name)); ZipHelper.ZipDirectoryToStream(tempDirectory, response.OutputStream); response.End(); } catch (Exception ex) { Debug.WriteLine(ex.ToString()); context.Response.StatusCode = 404; } finally { tempDirectory.DeleteWithPrejudice(); } } This was working fine, and returning the zip, otherwise if the file didn't exist returning 404. Then on the client side I could handle this: public bool Download() { try { using (var client = new WebClient()) { client.DownloadFile(name, tempFilePath); } } catch (Exception) { fileExists = false; } return fileExists; } But the problem now is two things. 1) I get System.Threading.ThreadAbortException: Thread was being aborted in the server side try-catch block. Usually this was just a file not found exception. I have no idea what or why that new exception is throwing? 2) Now that a different exception is throwing on the server side instead of the file not found, it would seem I can't use this set up for the application, because back on client side, any exception is assumed to be filenotfound. Any help, especially info on why this ThreadAbortException is throwing!?!? greatly appreciated. Cheers

• Is there an extension or a way to write an extension for firefox that allows a developer to refresh

  - by Kevin J

  I'm a developer, and I spend much of my day refreshing the webapps I work on. Occasionally, I'll encounter pages where POST data was submitted, and firefox will prompt me to Resend POST data or to Cancel. Now, I know that I can just redirect a page to itself to get rid of this warning, but I still want to keep this warning for our users; I just want to be able to skip it while developing. It's also not just on one page, but at many different points throughout the app, so it's not like I can just do if $debug==true then redirect or something like that. Basically just a minor convenience issue, but when I encounter the message 50-100 times a day, it can get aggravating. What I want to do is essentially have 3 options when refreshing: Resend POST data, cancel, or refresh without resending POST data The third option would be equivalent to clicking "enter" in the address bar (which is what I end up having to do). The problem with clicking enter is that I often have to "hard refresh" using ctrl+shift+r, but if I do this with POST data I have to click cancel, then click enter on the address bar, then do a hard refresh after that. I would instead like to press ctrl+shift+r, then continue hard refreshing the page without the POST data. Does anyone know how to do this? Through an extension or otherwise? It's totally a minor issue, but it's something that constantly bothers me and I actually think it would be quite a useful option. Thanks
