  • WPF Choppy Animation

    - by Chris Dunaway
    WPF Windows-XP SP3 I'm having a problem with a simple WPF animation. I use the following Xaml code (in XamlPad and also in a WPF project): <Page xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation" xmlns:sys="clr-namespace:System;assembly=mscorlib" xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml" > <Border Name="MyBorder" BorderThickness="10" BorderBrush="Blue" CornerRadius="10" Background="DarkRed" > <Rectangle Name="MyRectangle" Margin="10" StrokeDashArray="2.0,1.0" StrokeThickness="10" RadiusX="10" RadiusY="10" Stroke="Black" StrokeDashOffset="0"> <Rectangle.Triggers> <EventTrigger RoutedEvent="Rectangle.Loaded"> <BeginStoryboard> <Storyboard> <DoubleAnimation Storyboard.TargetName="MyRectangle" Storyboard.TargetProperty="StrokeDashOffset" From="0.0" To="3.0" Duration="0:0:1" RepeatBehavior="Forever" Timeline.DesiredFrameRate="30" /> </Storyboard> </BeginStoryboard> </EventTrigger> </Rectangle.Triggers> </Rectangle> </Border> </Page> It has the effect of causing the border to animate around the rectangle. After a fresh reboot of the machine, this animation is nice and smooth. However, I tend to leave my machine on all the time and after a period time elapses (I don't know how long), the animation starts stuttering and becomes choppy. I thought that it may be memory or resource issues, but after shutting down all other apps and any services that seem unnecessary, the stuttering still continues. However, after a system reboot, the animation is smooth again! I get the same symptoms in a WPF app or in XamlPad. In the case of the app, it doesn't seem to make any difference whether I run in the debugger or if I run the executable directly. I applied the patch at this link: http://support.microsoft.com/kb/981741 and I thought that it had taken care of the issue, but it seems not to have. I have seen some posts that might indicate that using transparency might affect animation, but as you can see, my xaml does not use transparency. Can anyone give me some suggestions on how to determine what the problem is? Are there any WPF diagnostic tools that might help? UPDATE: I have checked my video drivers and they are the latest version. (nVidia GeForce 8400 GS)

  • Windows Service HTTPListener Memory Issue

    - by crawshaws
    Hi all, Im a complete novice to the "best practices" etc of writing in any code. I tend to just write it an if it works, why fix it. Well, this way of working is landing me in some hot water. I am writing a simple windows service to server a single webpage. (This service will be incorperated in to another project which monitors the services and some folders on a group of servers.) My problem is that whenever a request is recieved, the memory usage jumps up by a few K per request and keeps qoing up on every request. Now ive found that by putting GC.Collect in the mix it stops at a certain number but im sure its not meant to be used this way. I was wondering if i am missing something or not doing something i should to free up memory. Here is the code: Public Class SimpleWebService : Inherits ServiceBase 'Set the values for the different event log types. Public Const EVENT_ERROR As Integer = 1 Public Const EVENT_WARNING As Integer = 2 Public Const EVENT_INFORMATION As Integer = 4 Public listenerThread As Thread Dim HTTPListner As HttpListener Dim blnKeepAlive As Boolean = True Shared Sub Main() Dim ServicesToRun As ServiceBase() ServicesToRun = New ServiceBase() {New SimpleWebService()} ServiceBase.Run(ServicesToRun) End Sub Protected Overrides Sub OnStart(ByVal args As String()) If Not HttpListener.IsSupported Then CreateEventLogEntry("Windows XP SP2, Server 2003, or higher is required to " & "use the HttpListener class.") Me.Stop() End If Try listenerThread = New Thread(AddressOf ListenForConnections) listenerThread.Start() Catch ex As Exception CreateEventLogEntry(ex.Message) End Try End Sub Protected Overrides Sub OnStop() blnKeepAlive = False End Sub Private Sub CreateEventLogEntry(ByRef strEventContent As String) Dim sSource As String Dim sLog As String sSource = "Service1" sLog = "Application" If Not EventLog.SourceExists(sSource) Then EventLog.CreateEventSource(sSource, sLog) End If Dim ELog As New EventLog(sLog, ".", sSource) ELog.WriteEntry(strEventContent) End Sub Public Sub ListenForConnections() HTTPListner = New HttpListener HTTPListner.Prefixes.Add("http://*:1986/") HTTPListner.Start() Do While blnKeepAlive Dim ctx As HttpListenerContext = HTTPListner.GetContext() Dim HandlerThread As Thread = New Thread(AddressOf ProcessRequest) HandlerThread.Start(ctx) HandlerThread = Nothing Loop HTTPListner.Stop() End Sub Private Sub ProcessRequest(ByVal ctx As HttpListenerContext) Dim sb As StringBuilder = New StringBuilder sb.Append("<html><body><h1>Test My Service</h1>") sb.Append("</body></html>") Dim buffer() As Byte = Encoding.UTF8.GetBytes(sb.ToString) ctx.Response.ContentLength64 = buffer.Length ctx.Response.OutputStream.Write(buffer, 0, buffer.Length) ctx.Response.OutputStream.Close() ctx.Response.Close() sb = Nothing buffer = Nothing ctx = Nothing 'This line seems to keep the mem leak down 'System.GC.Collect() End Sub End Class Please feel free to critisise and tear the code apart but please BE KIND. I have admitted I dont tend to follow the best practice when it comes to coding.

  • EJB client can't find a DataSource that tests successfully in WebLogic admin console

    - by suszterpatt
    Disclaimer: I'm completely new to JEE/EJB and all that, so bear with me. I have a simple EJB that I can successfully deploy using JDeveloper 11g's integrated WebLogic server and a remote database connection (JDBC). I have a DataSource named "PGY2" defined in WebLogic, and I can test it successfully from the admin console. Here's the code of the client I'm trying to test it with (generated entirely by JDev except for the three method calls on adminManager): public class AdminManagerClient { public static void main(String [] args) { try { final Context context = getInitialContext(); AdminManager adminManager = (AdminManager)context.lookup("Uran-AdminManager#hu.elte.pgy2.BACNAAI.UranEJB.AdminManager"); adminManager.addAdmin("root", "root", "Kovács Isten"); adminManager.addStudent("BACNAAI", "matt", "B Cs", 2005); adminManager.addTeacher("SIPKABT", "patt", "S P", "numanal", "Dr."); } catch (Exception ex) { ex.printStackTrace(); } } private static Context getInitialContext() throws NamingException { Hashtable env = new Hashtable(); // WebLogic Server 10.x connection details env.put( Context.INITIAL_CONTEXT_FACTORY, "weblogic.jndi.WLInitialContextFactory" ); env.put(Context.PROVIDER_URL, "t3://127.0.0.1:7101"); return new InitialContext( env ); } } But when I try to run this, I get the following error on the line with adminManager.addAdmin (that is, after the lookup): javax.ejb.EJBException: EJB Exception: ; nested exception is: Exception [EclipseLink-4002] (Eclipse Persistence Services - 1.0.2 (Build 20081024)): org.eclipse.persistence.exceptions.DatabaseException Internal Exception: java.sql.SQLException: Internal error: Cannot obtain XAConnection Creation of XAConnection for pool PGY2 failed after waitSecs:30 : java.sql.SQLException: Data Source PGY2 does not exist. Why can't the client find the data source, and how do I make it find it? EDIT: I took a closer look at WebLogic's output during deployment, and I found this. I have no idea what it means, but it may be relevant: <2010.05.20. 0:50:43 CEST> <Error> <Deployer> <BEA-149231> <Unable to set the activation state to true for the application 'PGY2'. weblogic.application.ModuleException: at weblogic.jdbc.module.JDBCModule.activate(JDBCModule.java:349) at weblogic.application.internal.flow.ModuleListenerInvoker.activate(ModuleListenerInvoker.java:107) at weblogic.application.internal.flow.DeploymentCallbackFlow$2.next(DeploymentCallbackFlow.java:411) at weblogic.application.utils.StateMachineDriver.nextState(StateMachineDriver.java:37) at weblogic.application.internal.flow.DeploymentCallbackFlow.activate(DeploymentCallbackFlow.java:74) Truncated. see log file for complete stacktrace weblogic.common.ResourceException: is already bound at weblogic.jdbc.common.internal.RmiDataSource.start(RmiDataSource.java:387) at weblogic.jdbc.common.internal.DataSourceManager.createAndStartDataSource(DataSourceManager.java:136) at weblogic.jdbc.common.internal.DataSourceManager.createAndStartDataSource(DataSourceManager.java:97) at weblogic.jdbc.module.JDBCModule.activate(JDBCModule.java:346) at weblogic.application.internal.flow.ModuleListenerInvoker.activate(ModuleListenerInvoker.java:107) Truncated. see log file for complete stacktrace >

  • Web Safe Area (optimal resolution) for web app design

    - by M.A.X
    I'm in the process of designing a new web app and I'm wondering for what 'web safe area' should I optimize the app layout and design. I did some investigation and thinking on my own but wanted to share this to see what the general opinion is. Here is what I found: Optimal Display Resolution: w3schools web stats seems to be the most referenced source (however they state that these are results from their site and is biased towards tech savvy users) http://www.w3counter.com/globalstats.php (aggregate data from something like 15,000 different sites that use their tracking services) StatCounter Global Stats Display Resolution (Stats are based on aggregate data collected by StatCounter on a sample exceeding 15 billion pageviews per month collected from across the StatCounter network of more than 3 million websites) NetMarketShare Screen Resolutions (marketshare.hitslink.com) (a web analytics consulting firm, they get data from browsers of site visitors to their on-demand network of live stats customers. The data is compiled from approximately 160 million visitors per month) Display Resolution Summary: There is a bit of variation between the above sources but in general as of Jan 2011 looks like 1024x768 is about 20%, while ~85% have a higher resolution of at least 1280x768 (1280x800 is the most common of these with 15-20% of total web, depending on the source; 1280x1024 and 1366x768 follow behind with 9-14% of the share). My guess would be that the higher resolution values will be even more common if we filter on North America, and even higher if we filter on N.American corporate users (unfortunately I couldn't find any free geographically filtered statistics). Another point to note is that the 1024x768 desktop user population is likely lower than the aforementioned 20%, seeing as the iPad (1024x768 native display) is likely propping up those number. My recommendation would be to optimize around the 1280x768 constraint (*note: 1280x768 is actually a relatively rare resolution, but I think it's a valid constraint range considering that 1366x768 is relatively common and 1280 is the most common horizontal resolution). Browser + OS Constraints: To further add to the constraints we have to subtract the space taken up by the browser (assuming IE, which is the most space consuming) and the OS (assuming WinXP-Win7): Win7 has the biggest taskbar footprint at a height of 40px (XP's and Vista's is 30px) The default IE8 view uses up 25px at the bottom of the screen with the status bar and a further 120px at the top of the screen with the windows title bar and the browser UI (assuming the default 'favorites' toolbar is present, it would instead be 91px without the favorites toolbar). Assuming no scrollbar, we also loose a total of 4px horizontally for the window outline. This means that we are left with 583px of vertical space and 1276px of horizontal. In other words, a Web Safe Area of 1276 x 583 Is this a correct line of thinking? I tried to Google some design best practices but most still talk about designing around 1024x768 which seems to be quickly disappearing. Any help on this would be greatly appreciated! Thanks.

  • Spring JPA and persistence.xml

    - by bmw0128
    I'm trying to set up a Spring JPA Hibernate simple example WAR for deployment to Glassfish. I see some examples use a persistence.xml file, and other examples do not. Some examples use a dataSource, and some do not. So far my understanding is that a dataSource is not needed if I have: <persistence-unit name="educationPU" transaction-type="JTA"> <provider>org.hibernate.ejb.HibernatePersistence</provider> <class>com.coe.jpa.StudentProfile</class> <properties> <property name="hibernate.connection.driver_class" value="com.mysql.jdbc.Driver" /> <property name="hibernate.connection.url" value="jdbc:mysql://localhost:3306/COE" /> <property name="hibernate.connection.username" value="root" /> <property name="show_sql" value="true" /> <property name="dialect" value="org.hibernate.dialect.MySQLDialect" /> </properties> </persistence-unit> I can deploy fine, but my EntityManager is not getting injected by Spring. My applicationContext.xml: <bean id="entityManagerFactory" class="org.springframework.orm.jpa.LocalEntityManagerFactoryBean"> <property name="persistenceUnitName" value="educationPU" /> </bean> <bean id="transactionManager" class="org.springframework.orm.jpa.JpaTransactionManager"> <property name="entityManagerFactory" ref="entityManagerFactory" /> </bean> <bean class="org.springframework.orm.jpa.support.PersistenceAnnotationBeanPostProcessor" /> <tx:annotation-driven transaction-manager="transactionManager" /> <bean id="StudentProfileDAO" class="com.coe.jpa.StudentProfileDAO"> <property name="entityManagerFactory" ref="entityManagerFactory" /> </bean> <bean id="studentService" class="com.coe.services.StudentService"> </bean> My class with the EntityManager: public class StudentService { private String saveMessage; private String showModal; private String modalHeader; private StudentProfile studentProfile; private String lastName; private String firstName; @PersistenceContext(unitName="educationPU") private EntityManager em; @Transactional public String save() { System.out.println("*** em: " + this.em); //em is null this.studentProfile= new StudentProfile(); this.saveMessage = "saved"; this.showModal = "true"; this.modalHeader= "Information Saved"; return "successs"; } My web.xml: <listener> <listener-class>org.springframework.web.context.ContextLoaderListener</listener-class> Are there any pieces I am missing to have Spring inject "em" in to StudentService?

  • OSGI classcast exception on felix

    - by Nico
    Hi, i'm fairly new to osgi and am trying to get a functional proof of concept together. The setup is that my common api is created in a bundle creatively named common-api.jar with no bundle activator, but it exports all it's interfaces. the one of interest in this situation is DatabaseService.java. I then have a Second bundle called systemx-database-service. That implements the database service interface. this works fine as in the activator of the implementation bundle i test the connection to the database and select some arbitraty values. I also register the service i want to be available to the other bundle's like so: context.registerService(DatabaseService.class.getName(), new SystemDatabaseServiceImpl(context), new Properties()); The basic idea being when you look for a service reference for a Database service you'll get back the SystemDatabaseService implementation. When i do a inspect service the output it this: -> inspect s c 69 System Database Service (69) provides services: ---------------------------------------------- objectClass = za.co.xxx.xxx.common.api.DatabaseService service.id = 39 which would lead me to believe that if i do this in a test bundle: context.getService(context.getServiceReference(DatabaseService.class)); i should get back an instance of DatabaseService.class, but alas no such luck. it simply seems like it cannot find the service. stick with me here my story gets stranger. figuring there is no where to go but up i wrote this monstrosity: for (Bundle bundle : bundles) { if (bundle.getSymbolicName().equals("za.co.xxx.xxx.database-service")) { ServiceReference[] registeredServices = bundle.getRegisteredServices(); for (ServiceReference ref : registeredServices) { DatabaseService service = (DatabaseService) context.getService(ref); // use service here. } } } } now i can actually see the service reference, but i get this error java.lang.ClassCastException: za.co.xxx.xxx.database.service.impl.SystemDatabaseServiceImpl cannot be cast to za.co.xxx.xx.common.api.DatabaseService which is crazy since the implementation clearly implements the interface! Any help would be appreciated. Please keep in mind i'm very new at the osgi way of thinking so my whole approach here might be flawed. oh. if anyone wants the manifests i can post them. and i'm using the maven-bnd-plugin to build and executing on felix. thanks Nico

  • JSON Feed Appears to be XHR when it should be JS

    - by Oscar Godson
    I don't get why it'd doing this with the 2nd feed (appearing as a XHR call rather than just JS [looking at it in Firefox/Firebug]). The 2nd feed has the exact same MIME type as Flickr's JSON feed, yet the PortlandOregon.gov one shows as XHR and i get a NULL callback when using $.getJSON and if i use $.ajax with a 'json' or 'jsonp' type i get nothing at all. If i do the Flickr one i get the normal "[object Object]" callback. Whats going on? Please help! This has been such a headache for about a week. And i have authorization to change the feed, but i have to request the change, so if anyone knows for absolute sure let me know that!

  • How to use AVCaptureSession to stream live preview video, then take a photo, then return to streaming

    - by Matthew
    I have an application that creates its own live preview prior to taking a still photo. The app needs to run some processing on the image data and thus is not able to rely on AVCaptureVideoPreviewLayer. Getting the initial stream to work is going quite well, using Apple's example code. The problem comes when I try to switch to the higher quality image to take the snapshot. In response to a button press I attempt to reconfigure the session for taking a full resolution photo. I've tried many variations but here is my latest example (which still does not work): - (void)sessionSetupForPhoto { [session beginConfiguration]; session.sessionPreset = AVCaptureSessionPresetPhoto; AVCaptureStillImageOutput *output = [[[AVCaptureStillImageOutput alloc] init] autorelease]; for (AVCaptureOutput *output in [session outputs]) { [session removeOutput:output]; } if ([session canAddOutput:output]){ [session addOutput:output]; } else { NSLog(@"Not able to add an AVCaptureStillImageOutput"); } [session commitConfiguration]; } I am consistently getting an error message just after the commitConfiguration line that looks like this: (that is to say, I am getting an AVCaptureSessionRuntimeErrorNotification sent to my registered observer) Received an error: NSConcreteNotification 0x19d870 {name = AVCaptureSessionRuntimeErrorNotification; object = ; userInfo = { AVCaptureSessionErrorKey = "Error Domain=AVFoundationErrorDomain Code=-11800 \"The operation couldn\U2019t be completed. (AVFoundationErrorDomain error -11800.)\" UserInfo=0x19d810 {}"; The documentation in XCode ostensibly provides more information for the error number (-11800), "AVErrorUnknown - Reason for the error is unknown."; Previously I had also tried calls to stopRunning and startRunning, but no longer do that after watching WWDC Session 409, where it is discouraged. When I was stopping and starting, I was getting a different error message -11819, which corresponds to "AVErrorMediaServicesWereReset - The operation could not be completed because media services became unavailable.", which is much nicer than simply "unknown", but not necessarily any more helpful. It successfully adds the AVCaptureStillImageOutput (i.e., does NOT emit the log message). I am testing on an iPhone 3g (w/4.1) and iPhone 4. This call is happening in the main thread, which is also where my original AVCaptureSession setup took place. How can I avoid the error? How can I switch to the higher resolution to take the photo? Thank you!

  • Would Like Multiple Checkboxes to Update World PNG Image Using Mogrify to FloodFill Countries With C

    - by socrtwo
    Hi. I'm seeing in another forum if the best way to do this is with Javascript or Ajax but I'm wondering if there is an even easier simpler way. I'm trying to create a web service where users can check which countries they have visited from a list of 175 or so and a World map image would then instantly update with a filled color. There are other similar services, but I'm envisioning mine to be both updating from checks in checkboxes and by clicking on the target country in the displayed image say with an imagemap. Additionally other solutions display all the visited countries in the same color. I would like different colors for different countries or at least for those countries that touch. Eventually I would like to include a feature that enables the choice of which colors to assign countries. I found a Sourceforge project called pwmfccd. It's simply an open source image of the world and the coordinates on the PNG image for all the countries. You can use mogrify from ImageMagick and floodfill to fill the countries with color. I have done this successfully, locally with batch files. My ISP has told me where mogrify is located, basically "/usr/bin/mogrify". I now have a horrendously complicated cgi script which if it worked is set to redraw the world map image with each checkbox. It's here. It also redraws the whole web page with each check. The web page starts here. Of course this is not at all efficient, and I think probably the real way to go is Ajax or Javascript, so that maybe just the image gets changed and redrawn, not the whole web page. Sorry I don't even know the difference between Javascript and Ajax and their relative merits at this point. I suppose you could make just one part of the image update with each check or click on the image instead of even just the image redrawing, but I have never even heard of a hint at being able to do that for irregularly shaped image elements like countries. So I guess an Image map and sister checkbox entries tied to mogrify events redrawing the user's personal copy of the image with an image refresh would be the only way to go. So how do you do this with something other than Javascript or Ajax or is that definitely the way to go and if so, how would you do it? Or can you after all cut up a web based image into irregular puzzle shaped piece which you can redraw individually at will. Thanks in advance for reading and considering answering this post.

When the above code is changed to accept dynamic inputs like, [WebMethod] public string DocumentRetrivalPDF(string docid, string pageno, string docFormat, string fileName) { try { ........ ....... string docRequest = "<soap:Envelope xmlns:soap='http://schemas.xmlsoap.org/soap/envelope/' xmlns:xsi='http://www.w3.org/2001/XMLSchema-instance' xmlns:xsd='http://www.w3.org/2001/XMLSchema'><soap:Body><document-retrieval id=" + docid + " page-number=" + pageno + " document-format=" + docFormat + " system='ops.epo.org' xmlns='http://ops.epo.org' /></soap:Body></soap:Envelope>"; ...... ........ return "responseTxt"; } catch (Exception ex) { return ex.Message; } } It return an "INTERNAL SERVER ERROR:500" can anybody help me on this???

  • How to modularize a JSF/Facelets/Spring application with OSGi?

    - by lexicore
    I'm working with very large JSF/Facelets applications which use Spring for DI/bean management. My applications have modular structure and I'm currently looking for approaches to standardize the modularization. My goal is to compose a web application from a number of modules (possibly depending on each other). Each module may contain the following: Classes; Static resources (images, CSS, scripts); Facelet templates; Managed beans - Spring application contexts, with request, session and application-scoped beans (alternative is JSF managed beans); Servlet API stuff - servlets, filters, listeners (this is optional). What I'd like to avoid (almost at all costs) is the need to copy or extract module resources (like Facelets templates) to the WAR or to extend the web.xml for module's servlets, filters, etc. It must be enough to add the module (JAR, bundle, artifact, ...) to the web application (WEB-INF/lib, bundles, plugins, ...) to extend the web application with this module. Currently I solve this task with a custom modularization solution which is heavily based on using classpath resources: Special resources servlet serves static resources from classpath resources (JARs). Special Facelets resource resolver allows loading Facelet templates from classpath resources. Spring loads application contexts via the pattern classpath*:com/acme/foo/module/applicationContext.xml - this loads application contexts defined in module JARs. Finally, a pair of delegating servlets and filters delegate request processing to the servlets and filters configured in Spring application contexts from modules. Last days I read a lot about OSGi and I was considering, how (and if) I could use OSGi as a standardized modularization approach. I was thinking about how individual tasks could be solved with OSGi: Static resources - OSGi bundles which want to export static resources register a ResourceLoader instances with the bundle context. A central ResourceServlet uses these resource loaders to load resources from bundles. Facelet templates - similar to above, a central ResourceResolver uses services registered by bundles. Managed beans - I have no idea how to use an expression like #{myBean.property} if myBean is defined in one of the bundles. Servlet API stuff - use something like WebExtender/Pax Web to register servlets, filters and so on. My questions are: Am I inventing a bicycle here? Are there standard solutions for that? I've found a mentioning of Spring Slices but could not find much documentation about it. Do you think OSGi is the right technology for the described task? Is my sketch of OSGI application more or less correct? How should managed beans (especially request/session scope) be handled? I'd be generally graefult for your comments.

  • JQGrid and JQuery Autocomplete

    - by Neff
    When implementing JQGrid 4.3.0, Jquery 1.6.2, and JQuery UI 1.8.16 Ive come across an issue with the Inline edit. When the inline edit is activated, some of the elements get assigned an auto complete. When the inline edit is canceld or saved, the auto complete does not always go away (selecting text by double clicking it then hitting delete, then hitting escape to exit row edit). Leaving the auto complete controls in edit mode when the row is no longer considered in edit mode. Perhaps you can tell me if there is a problem with the initialization or if I you are aware of an event post-"afterrestorefunc" that the fields can be returned to their "original" state. Original state being displayed as data in the JQGrid row. I've tried removing the DOM after row close, .remove() and .empty(): ... "afterrestorefunc": function(){ $('.ui-autocomplete-input').remove(); } ... but that causes other issues, such as the jqgrid is not able to find the cell when serializing the row for data or edit, and requires a refresh of the page, not just jqgrid, to be able to once again see the data from that row. Auto complete functionality for the element is created on the double click of the row: function CreateCustomSearchElement(value, options, selectiontype) { ... var el; el = document.createElement("input"); ... $(el).autocomplete({ source: function (request, response) { $.ajax({ url: '<%=ResolveUrl("~/Services/AutoCompleteService.asmx/GetAutoCompleteResponse") %>', data: "{ 'prefixText': '" + request.term + "', 'contextKey': '" + options.name + "'}", dataType: "json", type: "POST", contentType: "application/json; charset=utf-8", success: function (data) { response($.map(data.d, function (item) { return { label: Trim(item), value: Trim(item), searchVal: Trim(item) } })) } }); }, select: function (e, item) { //Select is on the event of selection where the value and label have already been determined. }, minLength: 1, change: function (event, ui) { //if the active element was not the search button //... } }).keyup(function (e) { if (e.keyCode == 8 || e.keyCode == 46) { //If the user hits backspace or delete, check the value of the textbox before setting the searchValue //... } }).keydown(function (e) { //if keycode is enter key and there is a value, you need to validate the data through select or change(onblur) if (e.keyCode == '13' && ($(el).val())) { return false; } if (e.keyCode == '220') { return false } }); } Other Sources: http://www.trirand.com/jqgridwiki/doku.php?id=wiki:inline_editing http://api.jqueryui.com/autocomplete/ Update: I tried only creating the autocomplete when the element was focused, and removing it when onblur. That did not resolve the issue either. It seems to just need the autocomplete dropdown to be triggered.

  • Rails ActiveResource Associations

    - by brad
    I have some ARes models (see below) that I'm trying to use associations with (which seems to be wholly undocumented and maybe not possible but I thought I'd give it a try) So on my service side, my ActiveRecord object will render something like render :xml => @group.to_xml(:include => :customers) (see generated xml below) The models Group and Customers are HABTM On my ARes side, I'm hoping that it can see the <customers> xml attribute and automatically populate the .customers attribute of that Group object , but the has_many etc methods aren't supported (at least as far as I can tell) So I'm wondering how ARes does it's reflection on the XML to set the attributes of an object. In AR for instance I could create a def customers=(customer_array) and set it myself, but this doesn't seem to work in ARes. One suggestion I found for an "association" is the just have a method def customers Customer.find(:all, :conditions => {:group_id => self.id}) end But this has the disadvantage that it makes a second service call to look up those customers... not cool I'd like my ActiveResource model to see that the customers attribute in the XML and automatically populate my model. Anyone have any experience with this?? # My Services class Customer < ActiveRecord::Base has_and_belongs_to_many :groups end class Group < ActiveRecord::Base has_and_belongs_to_many :customer end # My ActiveResource accessors class Customer < ActiveResource::Base; end class Group < ActiveResource::Base; end # XML from /groups/:id?customers=true <group> <domain>some.domain.com</domain> <id type="integer">266</id> <name>Some Name</name> <customers type="array"> <customer> <active type="boolean">true</active> <id type="integer">1</id> <name>Some Name</name> </customer> <customer> <active type="boolean" nil="true"></active> <id type="integer">306</id> <name>Some Other Name</name> </customer> </customers> </group>

  • Update tile notifcation with XML returned by web service

    - by tempid
    I have a Metro app in C# & XAML. The tile is updated periodically and I've used WebAPI to serve the tile notification XML. So far so good. I was then told that I cannot use WebAPI as the server that I was planning to host it on does not have .NET 4.5. No plans to install it anytime soon either. I had to change the WebAPI to a plain old Web service (.NET 3.5) which does the same thing - return tile notification XML. I've enabled HTTP-GET (I know, security concern) and was able to invoke the webservice like this - http://server/TileNotifications.asmx/[email protected] But ever since I made the switch, the tiles are not being updated. I've checked Fiddler and made sure the app is hitting the webservice and the XML is being returned correctly. But the tiles are not updated. If I replace it with the WebAPI, the tiles are updated. Do I need to do anything special with the web services? like decorating the web method with a custom attribute? Here's my web service code - [WebMethod] public XmlDocument GetTileData(string user) { // snip var xml = new XmlDocument(); xml.LoadXml(string.Format(@"<tile> <visual> <binding template='TileWideSmallImageAndText02'> <image id='1' src='http://server/images/{0}_wide.png'/> <text id='1'>Custom Field : {1}/text> <text id='2'>Custom Field : {2}</text> <text id='3'>Custom Field : {3}</text> </binding> <binding template='TileSquarePeekImageAndText01'> <image id='1' src='http://server/images/{0}_square.png'/> <text id='1'>Custom Field</text> <text id='2'>{1}</text> </binding> </visual> </tile>", value1, value2, value3, value4)); return xml; }

For commands it works fine, they are enabling or disabling correctly. But when i try to disable view and open perspective, that contains that view (myproject.view.input), it opened without that view, but also throws exception: !STACK 1 org.eclipse.ui.PartInitException: Could not create view: myproject.view.input at org.eclipse.ui.internal.ViewFactory.createView(ViewFactory.java:158) I can show full stacktrace if anyone want. I tried to debug my application and before i open my perspective whith that view, i checked currentState of my CommandState source provider, and all seemes to be ok: all variables values are correct and myproject.view.input.active = DISABLED Can anyone say, why exception is thrown? Thanks for any help. Sorry for big post and bad language

Code as below: /* Microsoft SQL Server Integration Services Script Component * Write scripts using Microsoft Visual C# 2008. * ScriptMain is the entry point class of the script.*/ using System; using System.Data; using System.Data.SqlClient; using Microsoft.SqlServer.Dts.Pipeline.Wrapper; using Microsoft.SqlServer.Dts.Runtime.Wrapper; [Microsoft.SqlServer.Dts.Pipeline.SSISScriptComponentEntryPointAttribute] public class ScriptMain : UserComponent { SqlConnection cnn = new SqlConnection(); IDTSConnectionManager100 cnManager; //string cmd; SqlCommand cmd = new SqlCommand(); public override void AcquireConnections(object Transaction) { cnManager = base.Connections.myConnection; cnn = (SqlConnection)cnManager.AcquireConnection(null); } public override void PreExecute() { base.PreExecute(); } public override void PostExecute() { base.PostExecute(); } public override void InputRows_ProcessInputRow(InputRowsBuffer Row) { while(Row.NextRow()) { DataTable dt = new DataTable(); cmd.Connection = cnn; cmd.CommandText = "OSPATTRIBUTE_GetOPNforOP"; cmd.CommandType = CommandType.StoredProcedure; cmd.Parameters.Add("@NK", SqlDbType.VarChar).Value = Row.OPNK.ToString(); cmd.Parameters.Add("@EDWSTARTDATE", SqlDbType.DateTime).Value = Row.EDWEFFECTIVESTARTDATETIME; SqlDataAdapter adapter = new SqlDataAdapter(cmd); adapter.Fill(dt); foreach (DataRow dtrow in dt.Rows) { OutputValidBuffer.AddRow(); OutputValidBuffer.OPNK = Row.OPNK; OutputValidBuffer.OSPTYPECODE = Row.OSPTYPECODE; OutputValidBuffer.ORGPROVTYPEDESC = Row.ORGPROVTYPEDESC; OutputValidBuffer.HEALTHSECTORCODE = Row.HEALTHSECTORCODE; OutputValidBuffer.HEALTHSECTORDESCRIPTION = Row.HEALTHSECTORDESCRIPTION; OutputValidBuffer.EDWEFFECTIVESTARTDATETIME = Row.EDWEFFECTIVESTARTDATETIME; OutputValidBuffer.EDWEFFECTIVEENDDATETIME = Row.EDWEFFECTIVEENDDATETIME; OutputValidBuffer.OPQI = Row.OPQI; OutputValidBuffer.OPNNK = dtrow[0].ToString(); OutputValidBuffer.OSPNAMETYPECODE = dtrow[1].ToString(); OutputValidBuffer.NAMETYPEDESC = dtrow[2].ToString(); OutputValidBuffer.OSPNAME = dtrow[3].ToString(); OutputValidBuffer.EDWEFFECTIVESTARTDATETIME1 = Row.EDWEFFECTIVESTARTDATETIME; OutputValidBuffer.EDWEFFECTIVEENDDATETIME1 = Row.EDWEFFECTIVEENDDATETIME; OutputValidBuffer.OPNQI = dtrow[6].ToString(); } } } public override void ReleaseConnections() { cnManager.ReleaseConnection(cnn); } } This is always skipping the first row. while(Row.NextRow()) is always bringing the second row of the input buffer. What am I doing wrong. Thanks

  • Selecting MediaTray in Java printing

    - by Rocket Surgeon
    I am trying to programmatically select a different media tray using Java Printing API. However, my document always gets printed to the default (TOP) media tray. I checked if the MediaTray attributes are supported using "isAttributeValueSupported()" method on javax.print.PrintService interface and I am getting the result as "true" for each MediaTray I pass. Here is my code: public void print( String printerName, com.company.services.document.transferobject.MediaTray tray, byte[] document) { String methodName = "print: "; logger.sendEvent(CLASS_NAME + methodName + "Start", EventType.INFO, this); if (printerName == null || "none".equals(printerName) || "?".equals(printerName) || "null".equals(printerName)) { logger.sendEvent("Please supply printer name, currently printerName is "+printerName, EventType.INFO, this); return; } DocFlavor flavor = DocFlavor.BYTE_ARRAY.AUTOSENSE; AttributeSet attributeSet = new HashAttributeSet(); attributeSet.add(new PrinterName(printerName, null)); javax.print.PrintService service = getService(printerName); if (service.isAttributeValueSupported(MediaTray.TOP, flavor, null)) { System.out.println("---------->>>>>>>>>Yes TOP" + " : Value : " + MediaTray.TOP.getValue()); } else { System.out.println("---------->>>>>>>>>Nope"); } if (service.isAttributeValueSupported(MediaTray.BOTTOM, flavor, null)) { System.out.println("---------->>>>>>>>>Yes BOTTOM" + " : Value : " + MediaTray.BOTTOM.getValue()); } else { System.out.println("---------->>>>>>>>>Nope"); } if (service.isAttributeValueSupported(MediaTray.MIDDLE, flavor, null)) { System.out.println("---------->>>>>>>>>Yes MIDDLE" + " : Value : " + MediaTray.MIDDLE.getValue()); } else { System.out.println("---------->>>>>>>>>Nope"); } if (service.isAttributeValueSupported(MediaTray.MANUAL, flavor, null)) { System.out.println("---------->>>>>>>>>Yes MANUAL" + " : Value : " + MediaTray.MANUAL.getValue()); } else { System.out.println("---------->>>>>>>>>Nope"); } if (service.isAttributeValueSupported(MediaTray.SIDE, flavor, null)) { System.out.println("---------->>>>>>>>>Yes SIDE" + " : Value : " + MediaTray.SIDE.getValue()); } else { System.out.println("---------->>>>>>>>>Nope"); } DocPrintJob printJob = service.createPrintJob(); try { byte[] textStream = document; PrintRequestAttributeSet pras = new HashPrintRequestAttributeSet(); pras.add(DocumentServiceConstant. DEFAULT_ONE_PRINT_COPY); pras.add(Sides.ONE_SIDED); Media standardTray= toStandardTray(tray); if (null != standardTray) { pras.add(standardTray); } Doc myDoc = new SimpleDoc(textStream, flavor, null); printJob.print(myDoc, pras); logger.sendEvent( " successfully printed ............ ", EventType.INFO, this); } catch (Throwable th) { logger.sendEvent(" Throwable : "+th.getLocalizedMessage(), EventType.INFO, this); ExceptionUtility .determineExceptionForServiceClient(th); } logger.sendEvent(CLASS_NAME + methodName + "END: ", EventType.INFO, this); } Any help will be greatly appreciated!

  • AD - DirectoryServices: VBNET2.0 - Speaking architecture...

    - by Will Marcouiller
    I've been mandated to write an application to migrate the Active Directory access models to another environment. Here's the context: I'm stuck with VB.NET 2005 and .NET Framework 2.0; The application must use the Windows authenticated user to manage AD; The objects I have to handle are Groups, Users and OrganizationalUnits; I intend to use the Façade design pattern to provider ease of use and a fully reusable code; I plan to write a factory for each of the objects managed (group, ou, user); The use of Attributes should be useful here, I guess; As everything is about the DirectoryEntry class when accessing the AD, it seems a good candidate for generic types. Obligatory features: User creates new OUs manually; User creates new group manually; User creates new user (these users are services accounts) manually; Application reads an XML file which contains the OUs, groups and users to create; Application informs the user about the OUs, groups and users that shall be created; User specifies the domain environment where to migrate the XML input file designated objects; User makes changes if needed, and launches the task operations; Application performs required by the XML input file operations against the underlying AD as specified by the user; Application informs the user upon completion. Linear features: User fetches OUs, groups, users; User changes OUs, groups, users; User deletes OUs, groups, users; The application logs AD entries and operations performed, plus errors and exceptions; Nice-to-have features: Application rollbacks operations on error or exception. I've been working for weeks now to get acquainted with the AD and the System.DirectoryServices assembly. But I don't seem to find a way to be fully satisfied with what I'm doing and always looking for better. I have studied Bret de Smet's Linq to AD on CodePlex, but then again, I can't use it as I'm stuck with .NET 2.0, so no Linq! But I've learned about Attributes, and seen that he's working with generic types as he codes a DirectorySource class to perform the operations for OUs, groups and users. Any suggestions? Thanks for any help, code sample, ideas, architural solution, everything!

  • jQuery, get datas in AJAX (done) then, display them as star (error)

    - by Tristan
    Hello, In my website, there are 2 steps : I get values from another domain with AJAX, it's numbers 100% working Then, i want to display those numbers in stars with this plugin (http://stackoverflow.com/questions/1987524/turn-a-number-into-star-rating-display-using-jquery-and-css) The error : the stars plugin does not work for the value i recieve from my ajax request, but it's working for my values for my domain which are not JS manipulated you can see a demo here http://www.esl.eu/fr/test/test_atome/?killcache=true PS: the data in ajax are provided in JSON-P so i wrote a parser which look like this: jQuery.ajax({ type: "get", dataType: "jsonp", url: "http://www.foo.com/", data: {demandeur: "monkey" }, cache: true, success: function(data, textStatus, XMLHttpRequest){ var obj = null, length = data.length; for (var i = 0; i < length; i++) { widget = "<p>AVERAGES<p>"; widget += "<p><span class='stars'>"; widget += data[i].services; widget += "</span></p>"; widget += "<p><span class='stars'>"; widget += data[i].qualite; widget += "</span></p>"; jQuery('#gotserv').html(widget); } } }); }); Then i have the star plugin after this function : $.fn.stars = function() { $(this).each(function() { // Get the value var val = parseFloat($(this).html()); // Make sure that the value is in 0 - 5 range val = val 5 ? 5 : (val < 0 ? 0 : val); // Calculate physical size var size = 16 * val; // Create stars holder var stars = $(''); // Adjust yellow stars' width stars.find('span').width(size); // Replace the numerical value with stars $(this).replaceWith(stars); }); I hope you understand, i don't know if i'm clear Thank you

  • "Emulating" Application.Run using Application.DoEvents

    - by Luca
    I'm getting in trouble. I'm trying to emulate the call Application.Run using Application.DoEvents... this sounds bad, and then I accept also alternative solutions to my question... I have to handle a message pump like Application.Run does, but I need to execute code before and after the message handling. Here is the main significant snippet of code. // Create barrier (multiple kernels synchronization) sKernelBarrier = new KernelBarrier(sKernels.Count); foreach (RenderKernel k in sKernels) { // Create rendering contexts (one for each kernel) k.CreateRenderContext(); // Start render kernel kernels k.mThread = new Thread(RenderKernelMain); k.mThread.Start(k); } while (sKernelBarrier.KernelCount > 0) { // Wait untill all kernel loops has finished sKernelBarrier.WaitKernelBarrier(); // Do application events Application.DoEvents(); // Execute shared context services foreach (RenderKernelContextService s in sContextServices) s.Execute(sSharedContext); // Next kernel render loop sKernelBarrier.ReleaseKernelBarrier(); } This snippet of code is execute by the Main routine. Pratically I have a list of Kernel classes, which runs in separate threads, these threads handle a Form for rendering in OpenGL. I need to synchronize all the Kernel threads using a barrier, and this work perfectly. Of course, I need to handle Form messages in the main thread (Main routine), for every Form created, and indeed I call Application.DoEvents() to do the job. Now I have to modify the snippet above to have a common Form (simple dialog box) without consuming the 100% of CPU calling Application.DoEvents(), as Application.Run does. The goal should be to have the snippet above handle messages when arrives, and issue a rendering (releasing the barrier) only when necessary, without trying to get the maximum FPS; there should be the possibility to switch to a strict loop to render as much as possible. How could it be possible? Note: the snippet above must be executed in the Main routine, since the OpenGL context is created on the main thread. Moving the snippet in a separated thread and calling Application.Run is quite unstable and buggy...
