  • How do I store more information in a marker?

    - by Sebastian
    Hello, I'm using Google Maps v3 and I build in the server side a json collection of location data. So when I receive that, I iterate through that collection and create a marker object for each and every one of them. For each of these markers, I bind them with the click event, so when the user clicks on a marker in the map, it displays an infoWindow with data related to the associated location. I have an array to store all the location got from the server that holds the retrieved json objects and their corresponding marker. The problem is that, even when I have an array that I can reference or iterate through, I need to not only get the marker object when the user clicks on them, but also the location object, that stores more information. I tried to mantain this array of objects and reference it from the calling object without success, because the function is called by the marker and not the location object. So I thought if it's possible to store more information in the google maps marker object like using a general purpose field. Please let me know if more information is needed. Thanks!

  • Structuring projects & dependencies of large winforms applications in C#

    - by Benjol
    UPDATE: This is one of my most-visited questions, and yet I still haven't really found a satisfactory solution for my project. One idea I read in an answer to another question is to create a tool which can build solutions 'on the fly' for projects that you pick from a list. I have yet to try that though. How do you structure a very large application? Multiple smallish projects/assemblies in one big solution? A few big projects? One solution per project? And how do you manage dependencies in the case where you don't have one solution. Note: I'm looking for advice based on experience, not answers you found on Google (I can do that myself). I'm currently working on an application which has upward of 80 dlls, each in its own solution. Managing the dependencies is almost a full time job. There is a custom in-house 'source control' with added functionality for copying dependency dlls all over the place. Seems like a sub-optimum solution to me, but is there a better way? Working on a solution with 80 projects would be pretty rough in practice, I fear. (Context: winforms, not web) EDIT: (If you think this is a different question, leave me a comment) It seems to me that there are interdependencies between: Project/Solution structure for an application Folder/File structure Branch structure for source control (if you use branching) But I have great difficulty separating these out to consider them individually, if that is even possible. I have asked another related question here.

  • Why use short-circuit code?

    - by Tim Lytle
    Related Questions: Benefits of using short-circuit evaluation, Why would a language NOT use Short-circuit evaluation?, Can someone explain this line of code please? (Logic & Assignment operators) There are questions about the benefits of a language using short-circuit code, but I'm wondering what are the benefits for a programmer? Is it just that it can make code a little more concise? Or are there performance reasons? I'm not asking about situations where two entities need to be evaluated anyway, for example: if($user->auth() AND $model->valid()){ $model->save(); } To me the reasoning there is clear - since both need to be true, you can skip the more costly model validation if the user can't save the data. This also has a (to me) obvious purpose: if(is_string($userid) AND strlen($userid) > 10){ //do something }; Because it wouldn't be wise to call strlen() with a non-string value. What I'm wondering about is the use of short-circuit code when it doesn't effect any other statements. For example, from the Zend Application default index page: defined('APPLICATION_PATH') || define('APPLICATION_PATH', realpath(dirname(__FILE__) . '/../application')); This could have been: if(!defined('APPLICATION_PATH')){ define('APPLICATION_PATH', realpath(dirname(__FILE__) . '/../application')); } Or even as a single statement: if(!defined('APPLICATION_PATH')) define('APPLICATION_PATH', realpath(dirname(__FILE__) . '/../application')); So why use the short-circuit code? Just for the 'coolness' factor of using logic operators in place of control structures? To consolidate nested if statements? Because it's faster?

  • WPF custom BalloonTips problem with multithreading

    - by Erika
    Hi, I have read other related question but i cant really get them to relate to this so I thought it were best to ask, Im pretty new to WPF and so on so please bear with me. I am using this http://www.codeproject.com/KB/WPF/wpf_notifyicon.aspx api to work with custom WPF Windows (in particular FancyBalloon). However, i'm coming across the following problem, I seem unable to start off BalloonTips in a separate thread ( i need this because i'm parsing emails and hence if there are 3 emails for instance, it displays the first email (that works fine), but when it comes to the second email it crashes with a TargetInvocationException , {"Specified element is already the logical child of another element. Disconnect it first."}. Thing is, im supposedly working with the same instance and i have attempted calling it to close it before, disposing it etc but to no avail. (then again if i dispose it, i cant create another instance as apparently WPF UI components must be called from a static thread so throughout the looping of emails + displaying balloon, i am trying to use the same BalloonTip. Any suggestions please? I am really at a loss here and i've been on it for quite a while now :/ I was wondering if there was anyone

  • UINavigationController crash because of pushing and poping UIViewControllers

    - by Wayne Lo
    My question is related to my discovery of a reason for UINavigationController to crash. So I will tell you about the discovery first. Please bare with me. The issue: I have a UINavigationController as as subview of UIWindow, a rootViewController class and a custom MyViewController class. The following steps will get a Exc_Bad_Access, 100% reproducible.: [myNaviationController pushViewController:myViewController_1stInstance animated:YES]; [myNaviationController pushViewController:myViewController_2ndInstance animated:YES]; Hit the left back tapBarItem twice (pop out two of the myViewController instances) to show the rootViewController. After a painful 1/2 day of try and error, I finally figure out the answer but also raise a question. The Solutio: I declared many objects in the .m file as a lazy way of declaring private variables to avoid cluttering the .h file. For instance, #impoart "MyViewController.h" NSMutableString*variable1; @implement ... -(id)init { ... varialbe1=[[NSMutableString alloc] init]; ... } -(void)dealloc { [variable1 release]; } For some reasons, the iphone OS may loose track of these "lazy private" variables memory allocation when myViewController_1stInstance's view is unloaded (but still in the navigation controller's stacks) after loading the view of myViewController_2ndInstance. The first time to tap the back tapBarItem is ok since myViewController_2ndInstance'view is still loaded. But the 2nd tap on the back tapBarItem gave me hell because it tried to dealloc the 2nd instance. Executing [variable release] resulted in Exc_Bad_Access because it pointed randomly (loose pointer). To fix this problem is simple, declare variable1 as a @private in the .h file. Here is my Question: I have been using the "lazy private" variables for quite some time without any issues until they are involved in UINavigationController. Is this a bug in iPhone OS? Or there is a fundamental misunderstanding on my part about Objective C? Please help.

  • Access denied when trying to read information about SharePoint groups

    - by strongopinions
    I am trying to get the membership of a group in WSS 3.0. I am doing this in an elevated permissions block. Here is the code: SPSecurity.RunWithElevatedPrivileges(delegate() { using (SPSite site = new SPSite(SPContext.Current.Site.ID)) { using (SPWeb rootWeb = site.RootWeb) { SPGroup gAdmins = rootWeb.SiteGroups["Admins"]; } } }); I get taken to the "access denied" SharePoint screen when I run this code. The group exists. The identity of the application pool for the web application is in the dbo role in the content database. The code works on my development server, but not on another server, which leads me to believe there is something wrong with the permissions or configuration on this server, maybe something in dcomcnfg? Here are some lines from the SharePoint log that seem to be related: PermissionMask check failed. asking for 0x08000000, have 0x00000000 Unknown SPRequest error occurred. More information: 0x80070005 Access Denied for /Pages/UserAdmin.aspx.

  • Problem with creation of scheduled task from IIS6 on SR2003

    - by Morten Louw Nielsen
    Hi, I am writing a webapplication using .NET. The webapp creates scheduled tasks using the System.Diagnostics.Process class, calling SCHTASKS.EXE with parameters. I have changed the identity on the app pool, to a specific domain user. The domain-user is local administrator on all the four webservers. From webserver01 I am creating tasks on webserver01 to webserver04. It works perfect for 3-5 days, but then it breaks. It gives me the following errormessage in a messagebox: "The application failed to initialize properly (0xc0000142). Click on OK to terminate the application." If I have the system in the broken state, and I change the identity of the app pool to Domain administrator, it works. As I change it back to my domain-user, it breaks again. If I reboot the server, it works again for the same amount of days, but will break again. It seems like a permission-related problem. I just don't understand why it works sometimes, and sometimes doesn't. I hope someone outthere has seen this problem! Looking forward to hear from you! Kind regards, Morten, Denmark

  • jQuery UI ThemeRoller - Installing themes

    - by CJM
    I'm trying to install jQuery UI with a ThemeRoller theme for the first time. I've downloaded jquery 1.4.2... I've downloaded jQuery UI with a couple of themes. I've tried to follow the instructions but they seem contradictory and don't seem to related to the downloaded files. When I try to use a datepicker... the datepicker functionality works, but it has the default (grey) style. This page refers to a folder/sub-folder/css files that don't exist. This page refers to a ui.theme.css file that doesn't exist. The downloads I received included the following: --demos --docs --external --themes ----base ----[theme name] --ui ----i8n ----minified --js So what do you put where? I've copied the js to the appropriate directory and linked it into my page. And I copied the themes/base folder as well, and linked into the jquery.ui.all.css file. Even the included demos only display the default (grey) styling. Where am I going wrong? The head section: <script type="text/javascript" src="/scripts/jquery-1.4.2.min.js"></script> <script type="text/javascript" src="/scripts/jquery-ui-1.8.custom.min.js"></script> <link rel="Stylesheet" href="/css/smoothness/jquery.ui.all.css" /> The body section: <script type="text/javascript"> $(function() { $("#datepicker").datepicker(); }); </script> <div> <p>Date: <input type="text" id="datepicker" /></p> </div>

  • Java RMI timeout in callback

    - by sakra
    We are using Java RMI for communication. An RMI client passes a processing request and an object with a callback method to an RMI server. The server invokes the callback when it is done with processing. The setup is similar to the one described in RMI Callbacks. Occasionally we are getting a "read time out" exception in the server upon invoking the callback method. The callback thread stalls for about a minute before the exception is raised. java.rmi.ConnectIOException: error during JRMP connection establishment; nested exception is: java.net.SocketTimeoutException: Read timed out at sun.rmi.transport.tcp.TCPChannel.createConnection(TCPChannel.java:286) at sun.rmi.transport.tcp.TCPChannel.newConnection(TCPChannel.java:184) at sun.rmi.server.UnicastRef.invoke(UnicastRef.java:110) at java.rmi.server.RemoteObjectInvocationHandler.invokeRemoteMethod(RemoteObjectInvocationHandler.java:178) at java.rmi.server.RemoteObjectInvocationHandler.invoke(RemoteObjectInvocationHandler.java:132) at $Proxy2.finished(Unknown Source) at com.unrisk.db.grid.GridTask.invokeCallback(com.unrisk.db.grid.GridTask:1292) at com.unrisk.db.grid.GridTask.invokeCallbacks(com.unrisk.db.grid.GridTask:1304) at com.unrisk.db.service.tasks.EquityMDTask.afterRun(com.unrisk.db.service.tasks.EquityMDTask:276) at com.unrisk.db.grid.GridTask.run(com.unrisk.db.grid.GridTask:720) at java.util.concurrent.ThreadPoolExecutor$Worker.runTask(ThreadPoolExecutor.java:886) at java.util.concurrent.ThreadPoolExecutor$Worker.run(ThreadPoolExecutor.java:908) at java.lang.Thread.run(Thread.java:619) Caused by: java.net.SocketTimeoutException: Read timed out at java.net.SocketInputStream.socketRead0(Native Method) at java.net.SocketInputStream.read(SocketInputStream.java:129) at java.io.BufferedInputStream.fill(BufferedInputStream.java:218) at java.io.BufferedInputStream.read(BufferedInputStream.java:237) at java.io.DataInputStream.readByte(DataInputStream.java:248) at sun.rmi.transport.tcp.TCPChannel.createConnection(TCPChannel.java:228) ... 12 more We are using Sun Java JDK 1.6.0_18 under Windows Server 2003 32-bit.

  • Cast exception when trying to create new Task Schedueler task.

    - by seaneshbaugh
    I'm attempting to create a new task in the Windows Task Scheduler in C#. What I've got so far is pretty much a copy and paste of http://bartdesmet.net/blogs/bart/archive/2008/02/23/calling-the-task-scheduler-in-windows-vista-and-windows-server-2008-from-managed-code.aspx Everything compiles just fine but come run time I get the following exception: Unable to cast COM object of type 'System.__ComObject' to interface type 'TaskScheduler.ITimeTrigger'. This operation failed because the QueryInterface call on the COM component for the interface with IID '{B45747E0-EBA7-4276-9F29-85C5BB300006}' failed due to the following error: No such interface supported (Exception from HRESULT: 0x80004002 (E_NOINTERFACE)). Here's all the code so you can see what I'm doing here without following the above link. TaskSchedulerClass Scheduler = new TaskSchedulerClass(); Scheduler.Connect(null, null, null, null); ITaskDefinition Task = Scheduler.NewTask(0); Task.RegistrationInfo.Author = "Test Task"; Task.RegistrationInfo.Description = "Just testing this out."; ITimeTrigger Trigger = (ITimeTrigger)Task.Triggers.Create(_TASK_TRIGGER_TYPE2.TASK_TRIGGER_DAILY); Trigger.Id = "TestTrigger"; Trigger.StartBoundary = "2010-05-12T06:15:00"; IShowMessageAction Action = (IShowMessageAction)Task.Actions.Create(_TASK_ACTION_TYPE.TASK_ACTION_SHOW_MESSAGE); Action.Id = "TestAction"; Action.Title = "Test Task"; Action.MessageBody = "This is a test."; ITaskFolder Root = Scheduler.GetFolder("\\"); IRegisteredTask RegisteredTask = Root.RegisterTaskDefinition("Background Backup", Task, (int)_TASK_CREATION.TASK_CREATE_OR_UPDATE, null, null, _TASK_LOGON_TYPE.TASK_LOGON_INTERACTIVE_TOKEN, ""); The line that is throwing the exception is this one ITimeTrigger Trigger = (ITimeTrigger)Task.Triggers.Create(_TASK_TRIGGER_TYPE2.TASK_TRIGGER_DAILY); The exception message kinda makes sense to me, but I'm afraid I don't know enough about COM to really know where to begin with this. Also, I should add that I'm using VS 2010 and I had to set the project to either be for x86 or x64 CPU's instead of the usual "Any CPU" because it kept giving me a BadImageFormatException. I doubt that's related to my current problem, but just in case I thought I might as well mention it.

  • Is VB Really Case Insensitive?

    - by Otaku
    I'm not trying to start an argument here, but for whatever reason it's typically stated that VB is case insensitive and C languages aren't (and somehow that is a good thing). But here's my question: Where exactly is VB case insensitive? When I type... Dim ss As String Dim SS As String ...into the VS2008 IDE the second one has a warning of "Local variable 'SS' is already declared in the current block". In VBA VBE, it doesn't immediately kick an error, but rather just auto-corrects the case. Am I missing something here with this argument that VB is not case sensitive? (Also, if you know or care to answer, why would that be a bad thing?) EDIT: Why am I even asking this question? I've used VB in many of it's dialects for years now, sometimes as a hobbyist, sometimes for small business-related programs in a workgroup. As of the last 6 months I've been working on a big project, much bigger than I anticipated. Much of the sample source code out there is in C#. I don't have any burning desire to learn C#, but if there are things I'm missing out on that C# offers that VB doesn't (an opposite would be VB.NET offers XML Literals), then I'd like to know more about that feature. So in this case, it's often argued that C languages are case sensitive and that's good and VB is case insensitive and that is bad. I'd like to know A) how exactly is VB case insensitive because every single example in the code editor becomes case sensititive (meaning case gets corrected) whether I want it or not and B) is this compelling enough for me to consider moving to C# if VB.NET case is somehow limiting what I could do with code?

  • Java SwingWorker still uses 98% CPU after it's done.

    - by RemiX
    I am new to the Java SwingWorker class, but I'm trying to get it to do some stuff in the background. That part works already, but now, when it is finished, the Windows Task Manager still shows that 70-98% of the CPU is still being used. Before I hit the 'Start' button it is only 3-15% and after I close the program it returns to those values. But what is still happening when the SwingWorker already reported being done?? I'll give you a simplified version of my code: I have this StereoProcessor extending SwingWorker, with doInBackground(): yLoop for(some values y) { for(some values x) { if(isCancelled()) break yLoop; else { setProgress(to some value); // do some non-SingWorker-related stuff } } } return returnValue; I call to this process through another code: stereoProcessor.addPropertyChangeListener(new PropertyChangeListener() { public void propertyChange(PropertyChangeEvent evt) { if(evt.getPropertyName().equals("state")) if(evt.getNewValue().equals(StereoProcessor.StateValue.DONE) { // do stuff } } } }); stereoProcessor.computeSomething(); // this method calls execute() That's about it, so I don't understand what it keeps doing. I tried putting some System.outs in the code in different places, but all stopped printing after a while. Does anyone know what's going on? Edit: I noticed the CPU also keeps running after a simple call to a method in StereoProcessor that doesn't even call execute()...

  • IIS 7 can't connect to SQLServer 2008

    - by Nicolas Cadilhac
    Sorry if this is the most seen question on the web, but this is my turn. I am trying to publish my asp.net mvc app on IIS 7 under MS Sql Server 2008. I am on a Windows Server 2008 virtual machine. I get the following classical error: A network-related or instance-specific error occurred while establishing a connection to SQL Server. The server was not found or was not accessible. Verify that the instance name is correct and that SQL Server is configured to allow remote connections. (provider: SQL Network Interfaces, error: 26 - Error Locating Server/Instance Specified) Under SQLServer, Allow remote connections is checked. My connection string is: Data Source=.\MSSQLSERVER;Initial Catalog=mydbname;User Id=sa;Password=mypassword I also tried with no username/password and "Integrated Security=true". There is only one instance of SQLServer installed. I tried to access my web page locally and remotely. There is no active firewall on the virtual machine. Thx for your help.

  • gcc: Do I need -D_REENTRANT with pthreads?

    - by stefanB
    On Linux (kernel 2.6.5) our build system calls gcc with -D_REENTRANT. Is this still required when using pthreads? How is it related to gcc -pthread option? I understand that I should use -pthread with pthreads, do I still need -D_REENTRANT? On a side note, is there any difference that you know off between the usage of REENTRANT between gcc 3.3.3 and gcc 4.x.x ? When I use -pthread gcc option I can see that _REENTRANT gets defined. Will omitting -D_REENTRANT from command line make any difference, for example could some objects be compiled without multithreaded support and then linked into binary that uses pthreads and will cause problems? I assume it should be ok just to use: g++ -pthread > echo | g++ -E -dM -c - > singlethreaded > echo | g++ -pthread -E -dM -c - > multithreaded > diff singlethreaded multithreaded 39a40 > #define _REENTRANT 1 We're compiling multiple static libraries and applications that link with the static libraries, both libraries and application use pthreads. I believe it was required at some stage in the past but want to know if it is still required. Googling hasn't returned any recent information mentioning -D_REENTRANT with pthreads. Could you point me to links or references discussing the use in recent version of kernel/gcc/pthread? Clarification: At the moment we're using -D_REENTRANT and -lpthread, I assume I can replace them with just g++ -pthread, looking at man gcc it sets the flags for both preprocessor and linker. Any thoughts?

  • Subscription Management with Merchant Account via API

    - by Josh
    I'm researching gateways/vendors that provide the ability to create subscription based transitions for merchant accounts. In other words, I want to allow customers to signup for a subscription for a website service that charges once a month. Authorize.Net has an ARB (Automated Recurring Billing) Module. The cost is cheap, $10 a month for the service, with unlimited subscriptions, and they have an API that allows XML or SOAP access to create, update and cancel. The LARGE negative of the service is that it doesn't have elegant way to obtain the current status of a subscription. They can send a daily email with an attached CSV file, or someone can login into the site and review statuses – neither is an enterprise solution. The parent company "CyberSource" has a "Recurring Billing Service" which implies a more robust solution, including API access to subscription information. I’m currently waiting for a sales call back on costs related to the service. I also looked at PayPal's Recurring Billing Service, but that appears to require that users are redirected to the PayPal site to signup for the subscription -- again, not an an elegant solution. Does anyone know of any other vendors/gateways that offer subscription service, that meet the following criteria: Vendor/Gateway must host the credit card number and be PCI compliant Have an API that accessible via a Web Service, Post over HTTPS or SOAP Have an API that allows querying the status of subscriptions and/or the ability to query for activity since a certain date. Thanks in advance for your suggestions.

  • Loop through all cells in Xceed DataGrid for WPF?

    - by ewall
    I am changing the background color of the cells when the user has made an edit. I would like to return all cells to normal colors when the changes are saved (or reverted). It's easy enough to set the cell's original background color (as stored in the parent row). But I can't figure out how to loop through all the cells in the table to reset them. I found an article in the Xceed Knowledge Base called "How to iterate through the grid's rows"... which you would think would be perfect, right? Wrong; the properties (or methods) like .DataRows, .FixedHeaderRows, etc. mentioned in the article are from an older/defunct Xceed product. This forum thread recommends using the DataGrid's .Items property, which in my case returns a collection of System.Data.DataRowViews... but I can't find any way to cast that (or any of its related elements) up to the Xceed.Wpf.DataGrid.DataCells I need to change the background color. In short, how do I loop through the rows and cells so I can reset the background property?

  • Visual studio debug console sometimes stays open and is impossible to close

    - by JC
    Hey, Sometimes when I run an application from Visual Studio and it crashes or I stop it using the stop button in the debug menu (Debug-Stop Debugging (Shift-F5)), the console of said application stays open... and never closes. I cannot close it by clicking the 'x' button in the top right corner. I cannot kill the process as it is not even listed in taskmgr. I have seen this problem documented in different places on the web, but no solution so far. I am running on windows XP SP3, using visual studio 2008 w/ SP1. 1- What could be causing this ? 2- Is there a fix ? thanks alot. JC EDIT: There is no MyApp.vshost.exe process to close, and closing visual studio does not close the console either. Worse even, if I try to restart my computer windows will hang and never close, I need to do a forced shut down. EDIT #2 : (from Brad Sullivan, Program Manager - Visual Studio Debugger on March 2nd) [...] this issue is likely not in Visual Studio since it also occurs in scenarios where Visual Studio is not present. We are in the process of handing over our investigation to the Windows Servicing team. But for now, removing the KB978037 update and it's related files seems to work.

  • Lucene - querying with long strings

    - by Mikos
    I have an index, with a field "Affiliation", some example values are: "Stanford University School of Medicine, Palo Alto, CA USA", "Institute of Neurobiology, School of Medicine, Stanford University, Palo Alto, CA", "School of Medicine, Harvard University, Boston MA", "Brigham & Women's, Harvard University School of Medicine, Boston, MA" "Harvard University, Cambridge MA" and so on... (the bottom-line being the affiliations are written in multiple ways with no apparent consistency) I query the index on the affiliation field using say "School of Medicine, Stanford University, Palo Alto, CA" (with QueryParser) to find all Stanford related documents, I get a lot of false +ves, presumably because of the presence of School of Medicine etc. etc. (note: I cannot use Phrase query because of variability in the way affiliation is constructed) I have tried the following: Use a SpanNearQuery by splitting the search phrase with a whitespace (here I get no results!) Tried boosting (using ^) by splitting with the comma and boosting the last parts such as "Palo Alto CA" with a much higher boost than the initial phrases. Here I still get lots of false +ves. Any suggestions on how to approach this? If SpanNearQuery the way to go, Any ideas on why I get 0 results?

  • Eclipse Plugin does not work in FlashBuilder/FlexBuilder Standalone

    - by Janosch
    Hi, created an Eclipse plugin that contributes to the UI by a new project wizard a new menu in the context menu of projects in the Package Explorer a new project nature + builder a new preference page for the plugin The plugin works fine when installed in a normal Eclipse instance with Flex/Flashbuilder as plugin. The problem now is, that the plugin never gets activated when i install it in a Flex/Flashbuilder Standalone instance. Neither of the features described above is available. I even have no idea how to debug this, error-log (workspace/.metadata/.log) the following message appears, (but i dont think it is related to the problem) !ENTRY org.eclipse.ui.workbench 2 0 2009-07-20 17:51:17.984 !MESSAGE A handler conflict occurred. This may disable some commands. !SUBENTRY 1 org.eclipse.ui.workbench 2 0 2009-07-20 17:51:17.984 !MESSAGE Conflict for 'org.eclipse.ui.navigate.openResource': HandlerActivation(commandId=org.eclipse.ui.navigate.openResource, handler=ActionDelegateHandlerProxy(null,org.eclipse.ui.internal.ide.handlers.OpenResourceHandler), expression=AndExpression(ActionSetExpression(org.eclipse.ui.NavigateActionSet,org.eclipse.ui.internal.WorkbenchWindow@1c45731),WorkbenchWindowExpression(org.eclipse.ui.internal.WorkbenchWindow@1c45731)),sourcePriority=16640) HandlerActivation(commandId=org.eclipse.ui.navigate.openResource, handler=ActionDelegateHandlerProxy(null,org.eclipse.ui.internal.ide.handlers.OpenResourceHandler), expression=AndExpression(ActionSetExpression(com.adobe.flexbuilder.standalone.navigate,org.eclipse.ui.internal.WorkbenchWindow@1c45731),WorkbenchWindowExpression(org.eclipse.ui.internal.WorkbenchWindow@1c45731)),sourcePriority=16640) In the "Configuration Details" my feature doesn't show up in the *** Features: section and my plugin doesn't show up in the *** Plugin-in Registry: section. But they appear under Configured features and Configured plug-ins. Starting FlashBuilder with -clean didn't solve the problem. (the start command is now "C:\Programme\Adobe\Flash Builder Beta\Gumbo.exe" -clean) My plugin depends on org.eclipse.ui, org.eclipse.core.runtime, org.eclipse.core.resources, com.adobe.flexbuilder.project com.adobe.flexbuilder.project.ui com.adobe.flexbuilder.ui All of these should be available, as i see it. (and an error should be generated if they were not, i hope)

  • iPhone - openAL stops playing if I record with AVAudioRecorder

    - by Oscar Peli
    Hi there, this is an iPhone-related question: I use openAL to play some sound (I have to manage gain, pitch, etc.). I want to record what I'm playing and I use AVAudioRecorder but when I "prepareToRecord" openAL stops to play audio. What's the problem? Here is the record IBAction I use: - (IBAction) record: (id) sender { NSError *error; NSMutableDictionary *settings = [NSMutableDictionary dictionary]; [settings setValue: [NSNumber numberWithInt:kAudioFormatLinearPCM] forKey:AVFormatIDKey]; [settings setValue: [NSNumber numberWithFloat:8000.0] forKey:AVSampleRateKey]; [settings setValue: [NSNumber numberWithInt: 1] forKey:AVNumberOfChannelsKey]; [settings setValue: [NSNumber numberWithInt:16] forKey:AVLinearPCMBitDepthKey]; [settings setValue: [NSNumber numberWithBool:NO] forKey:AVLinearPCMIsBigEndianKey]; [settings setValue: [NSNumber numberWithBool:NO] forKey:AVLinearPCMIsFloatKey]; NSURL *url = [NSURL fileURLWithPath:FILEPATH]; self.recorder = [[AVAudioRecorder alloc] initWithURL:url settings:settings error:&error]; self.recorder.delegate = self; self.recorder.meteringEnabled = YES; [self.recorder prepareToRecord]; [self.recorder record]; } Thanks

  • model not showing up in django admin.

    - by Zayatzz
    Hi. I have ceated several django apps and stuffs for my own fund and so far everything has been working fine. Now i just created new project (django 1.2.1) and have run into trouble from 1st moments. I created new app - game and new model Game. i created admin.py and put related stuff into it. Ran syncdb and went to check into admin. Model did not show up there. I proceeded to check and doublecheck and read through previous similar threads: http://stackoverflow.com/questions/1839927/registered-models-do-not-show-up-in-admin http://stackoverflow.com/questions/1694259/django-app-not-showing-up-in-admin-interface But as far as i can tell, they dont help me either. Perhaps someone else can point this out for me. models.py in game app: # -*- coding: utf-8 -*- from django.db import models class Game(models.Model): type = models.IntegerField(blank=False, null=False, default=1) teamone = models.CharField(max_length=100, blank=False, null=False) teamtwo = models.CharField(max_length=100, blank=False, null=False) gametime = models.DateTimeField(blank=False, null=False) admin.py in game app: # -*- coding: utf-8 -*- from jalka.game.models import Game from django.contrib import admin class GameAdmin(admin.ModelAdmin): list_display = ['type', 'teamone', 'teamtwo', 'gametime'] admin.site.register(Game, GameAdmin) project settings.py: MIDDLEWARE_CLASSES = ( 'django.middleware.common.CommonMiddleware', 'django.contrib.sessions.middleware.SessionMiddleware', 'django.middleware.csrf.CsrfViewMiddleware', 'django.contrib.auth.middleware.AuthenticationMiddleware', 'django.contrib.messages.middleware.MessageMiddleware', ) ROOT_URLCONF = 'jalka.urls' TEMPLATE_DIRS = ( "/home/projects/jalka/templates/" ) INSTALLED_APPS = ( 'django.contrib.auth', 'django.contrib.contenttypes', 'django.contrib.sessions', 'django.contrib.sites', 'django.contrib.messages', 'django.contrib.admin', 'game', ) urls.py: from django.conf.urls.defaults import * # Uncomment the next two lines to enable the admin: from django.contrib import admin admin.autodiscover() urlpatterns = patterns('', # Example: # (r'^jalka/', include('jalka.foo.urls')), (r'^admin/', include(admin.site.urls)), ) Alan.

  • Open source Java CMS for Google App Engine?

    - by markvgti
    I am looking for an open source Java CMS (Web CMS, actually) to run on Google App Engine. I have looked at related older questions on this topic (What CMS runs on Google AppEngine?, CMS over Google App Engine, with SEO etc.) but the problem is that they all largely list Python-based CMSes. Plus these questions are pretty old, and since GAE is a fast-moving target, I thought it might be worthwhile to ask again. I want a CMS for creating some websites (for myself and for others), but would rather not start writing one from scratch. A "good" (very subjective, I know) open source WCMS allows me to start using a product, while still being able to add to/extend the product/project. On the one hand I am looking for a somewhat mature product/project, on the other hand it's easier to start contributing to the development cycle of a young product/project (conflicting, I know :-). Here are some features that would be preferable: [X]HTML/XML/CSS based templating Ability to create multiple blogs Galleries Ability to create a "Downloads" section (is this pretty much standard?) Separate management for digital assets (images, PDFs, binary files etc.) Roles like "Administrator", "Editor", "Contributor" etc. (or their equivalents) Ability to move/reorganize pages Export to PDF Reformat content for printing Is the CMS you are about to suggest especially well-suited to publishing an online book? My idea is that while the book may be offered as a downloadable eBook, the latest, most current version will be the one available on the website.

  • Creating a Custom Design-Time Environment

    - by Charlie
    Hello all, My question is related to the design-time support of WPF. From MSDN I read, The WPF Designer provides a framework and a public API which you can use to implement custom adorners, tools, property editors, and designers. But the vast majority of the examples I have found are trivial, and do not illustrate much concerning the creation of a customized designer in an existing WPF application. We have migrated our application from Windows Forms to WPF over the past year, and the next step will be to take an existing WinForms Panel designer, and rewrite it in WPF. Suffice it to say that this will be a huge project. But I don't even know where to begin. I am wondering if any of you have had similar experiences writing a customized designer for a WPF application, and what it was like. Even better, if you could compare and contrast the functionality between the WinForms designer and the WPF designer, or explain the transition from the former to the latter, that would be helpful. If you know of any simple examples that demonstrate a customized design environment (with custom controls, etc.) that would be extremely beneficial. All in all, I am just wondering if many people have undertaken this yet, and what their results have been. EDIT: To clarify, yes, I am talking about hosting a WPF designer. It appears that this may not even be possible, which is a huge setback. Here is a screenshot of our current WinForms designer. As you can see, it is used to create customized user interfaces. You can drag custom controls onto it and design them, then put the panel into a "run mode" in which all of the controls become functional. Short of spending months writing our designer, would this be possible in WPF? What about .NET 4.0 and VS2010? Will those add any designer functionality?

  • Can you use gzip over SSL? And Connection: Keep-Alive headers

    - by magenta
    I'm evaluating the front end performance of a secure (SSL) web app here at work and I'm wondering if it's possible to compress text files (html/css/javascript) over SSL. I've done some googling around but haven't found anything specifically related to SSL. If it's possible, is it even worth the extra CPU cycles since responses are also being encrypted? Would compressing responses hurt performance? Also, I'm wanting to make sure we're keeping the SSL connection alive so we're not making SSL handshakes over and over. I'm not seeing Connection: Keep-Alive in the response headers. I do see Keep-Alive: 115 in the request headers but that's only keeping the connection alive for 115 milliseconds (seems like the app server is closing the connection after a single request is processed?) Wouldn't you want the server to be setting that response header for as long as the session inactivity timeout is? I understand browsers don't cache SSL content to disk so we're serving the same files over and over and over on subsequent visits even though nothing has changed. The main optimization recommendations are reducing the number of http requests, minification, moving scripts to bottom, image optimization, possible domain sharding (though need to weigh the cost of another SSL handshake), things of that nature.
