  • GWT MVP with a table

    - by Benju
    When working with MVP in GWT how would you work with a table? For example if you had a table of users does your view look like this? public interface MyDisplay{ HasValue<User> users(); } or would it be more like this? public interface MyDisplay{ HasValue<TableRow> rows(); } MVP makes a ton of sense until you start dealing with widgets that need to display lists of non-primitive data. Can anybody shed some light? This mailing list archive appears to ask the same question but never reaches a solid resolution... http://www.mail-archive.com/[email protected]/msg24546.html

  • how to change strip.text labels in ggplot with facet and margin=TRUE

    - by Andreas
    I have looked here but still can't figure it out. How do I change the strip.text.x labels in a ggplot with faceting? Specifically I am using facet_grid with margins. The strip.text label for the margin is "(all)" - but since I am in a non-english speaking country I would rather write "Total" or something similar in my native tongue. opts(stip.text.x=c(levels(facetvariabel,"Total")) does not work. Any ideas? Example (not really the best dataset for this - but I guess it will work) ggplot(cars, aes(x=dist))+geom_bar()+facet_grid(.~speed, margin=T)

  • openquery issue in SQL Server

    - by George2
    Hello everyone, I am using SQL Server 2008 (let us call this source database server in this question discussion), and in SSMS, I have created a linked server to another SQL Server 2008 database (let us call this destination database server in this question discussion). When I issue statement -- select * from [linked server name].[database name].[dbo].[table name], error will be returned, Linked server "ZS" The OLE DB access interface "SQLNCLI10" returned "NON-CLUSTERED and NOT INTEGRATED "Index" ix_foo_basic_info_nf ", which is incorrect bookmark ordinal 0. When I issue statement -- select * from openquery([linked server name],'select * from [table name]'), there will be no errors, any ideas what is wrong? thanks in advance, George

  • Capture Silverlight 4 event when panel clicked

    - by Eric J.
    I have a small Silverlight 4 app that essentially consists of a grid containing a label and a combo box. When I click the label, I replace it with a second text box so that I can edit the label (much the way you can edit the name of a Silverlight control in VS2010). I have a LostFocus event handler on the text box that will end editing when the control loses focus (restoring the updated label). Trouble is, users tend to click on the panel when they are done editing rather than on another control (or hitting Enter, which is also supported). I tried adding a left mouse down event handler to the panel. However, that only fires when the text box does not have the focus (I guess the text box captured the mouse?) Is there an approach to recognize that a non-input control was clicked that would enable me to terminate edit mode?

  • Synonym for "Many-to-Many" relationship (relational databases)

    - by Byron
    What's a synonym for a "many-to-many" relationship? I've finished writing an object-relational mapper but I'm still stumped as to what to name the function that adds that relation. addParent() and addChild() seemed quite logical for the many-to-one/one-to-many and addSuperclass() for one-to-one inheritance, but addManyToMany() would sound quite unintuitive to an object-oriented programmer. addSibling() or addCousin() doesn't really make sense either. Any suggestions? And before you dismiss this as a non-programming question, please remember that consistent naming schemes and encapsulation are pretty integral to programming :)

  • Asterisk AGI framework for IVR; Adhearsion alternative?

    - by tedbehling
    I am trying to get started writing scalable, telecom-grade applications with Asterisk and Ruby. I had originally intended to use the Adhearsion framework for this, but it does not have the required maturity and its documentation is severely lacking. AsteriskRuby seems to be a good alternative, as it's well documented and appears to be written by Vonage. Does anyone have experience deploying AGI-based IVR applications? What framework, if any, did you use? I'd even consider a non-Ruby one if it's justified. Thanks!

  • Explore a COM Object in PHP

    - by shaiss
    What would be the proper way to explode a COM object for debugging? I have a 3rd party function that returns a multilevel object. The documentation is non existant, so I'd like to be able to echo everything out of the object or debug it in Komodo IDE. Komodo just says Object and nothing else. Maybe convert to array? I know some of the existing options such as $com->Status, but there are more variables returned that I'd like to know what they are.

  • jquery validation of controls

    - by Vinodtiru
    Hi , I am looking at validation of some text boxes for somethings like required, minlength, max length, email etc... I am able to get examples that work fine on submit button on page. I want to do this validation on a button click which will only raise a ajax request and not submit of page. On internet all the sample is found was with submit button. Is there a easy way to change this code a little bit o make it work for non submit button click or any new jquery or java plugin to do the same. I am using the jquery.validation.js for now. This works with submit buttons. Any kind of help with suggestion or help is appreciated. Thanks in advance.

  • Rails, REST Architecture and HTML 5: Cross domain requests with pre-flight requests

    - by Orion
    While working on a project to make our site HTML 5 friendly, we were eager to embrace the new method for Cross Domain requests (no more posting through hidden iframes!!!). Using the Access Control specification we begin setting up some tests to verify the behaviour of various browsers. The current Rails RESTful architecture relies on the four HTTP verbs: GET, POST, PUT, DELETE. However in the Access Control spec, it dictates that non-simple methods (PUT, DELETE) require a pre-flight request using the HTTP verb OPTIONS. In addition during testing we discovered that Firefox 3.5.8 pre-flight POST requests as well. My question is this. Is anyone aware of any project for the Rails framework working to address the issue? If not, any opinions about the best strategy to support the OPTIONS method, since it has to support the routes for all the POST, PUT, DELETE methods?

  • What event do I need to supress to stop IE from "Dinging" when I press enter in a text box?

    - by scunliffe
    On simple forms with one text box pressing enter submits the form (and this is great for easy search forms) However on a form with multiple fields, pressing Enter in an input="text" box won't do anything (e.g. submit) but in IE it "Dings" as if you have tried to delete an undeletable object. The question is... what event do I need to suppress in IE to stop this sound? e.g. if I have a username/password form, I DO want the enter key to submit the form, but I certainly don't want the "error" sound. Example site with the sound: http://www.sears.com/shc/s/StoreLocatorView?storeId=10153&catalogId=12605 Just press Enter in any of the text fields. Ding!, Ding!, Ding! Non-IE users, the sound is the: Program Events Windows Default Beep ("Windows XP Ding.wav")

  • Is it possible to get an NSView to pass rightMouseDown: to the next responder without subclassing?

    - by Benedict Cohen
    I have a view which contains a few subviews: mainView subViewA subViewB SubViewC mainView is an NSView constructed from a nib and is controlled with an NSViewController subclass. The subviews are standard views such as NSTextField and NSImageView and are configured to be non-editable. I want mainView to receive rightMouseDown: even when the event is triggered in one of the subviews. The default implementation of rightMouseDown: in NSResponder passes the event to the next responder, but NSView changes the default behaviour and does not pass it to the next responder. I could subclass all of the subviews but this doesn't seem like a very elegant or maintainable solution. How can I get the subviews to pass rightMouseDown: messages to the next responder without subclassing all of the subviews?

  • AS3 Event Bubbling outside of the Scenegraph/DisplayList

    - by Brian Heylin
    Hi just wondering if it is possible to take advantage of event bubbling in non display list classes in AS3. For example in the model of an application where there is a City class that contains many Cars. What methods are there to attach an event listener to a City object and receive events that bubble up from the child Cars. To clarify The City and Car objects are not part of the display list, they are not DisplayObjects. So can bubbling be implemented outside of the display list somehow? As far as I know, this is not possible without manually attaching event listeners to each Car object and re dispatching the event from the City object. Anyone else have a cleaner solution?

  • wpf DependencyProperty Not accepting default value for short

    - by biju
    Hi, I was trying to use tis depencency property in my code but it gives me error says that Default value type does not match type of property 'MyProperty'.But short should accept 0 as default value.Ans also if i try to give null as default value it works..even if its a non nullabel type.How come this happens.. public short MyProperty { get { return (short)GetValue(MyPropertyProperty); } set { SetValue(MyPropertyProperty, value); } } // Using a DependencyProperty as the backing store for MyProperty. This enables animation, styling, binding, etc... public static readonly DependencyProperty MyPropertyProperty = DependencyProperty.Register("MyProperty", typeof(short), typeof(Window2), new UIPropertyMetadata(0));

  • Zend_Form -> Nicely change setRequired() validate message

    - by dittonamed
    Say I create a text element like this: $firstName = new Zend_Form_Element_Text('firstName'); $firstName->setRequired(true); Whats the best way to change the default error message from: Value is empty, but a non-empty value is required to a custom message? I read somewhere that to replace the message, just use addValidator(..., instead (NO setRequired), like this: $firstName = new Zend_Form_Element_Text('firstName'); $firstName->addValidator('NotEmpty', false, array('messages'=>'Cannot be empty')); but in my testing, this doesn't work - it doesn't validate at all - it will pass with an empty text field. Using both (addValidator('NotEmp.. + setRequired(true)) at the same time doesn't work either - it double validates, giving two error messages. Any ideas? Thanks!

  • Absolute reRendering using RichFaces

    - by wheelie
    Hey there, I am implementing copy/paste functionality for a complex object tree, this means you can copy an object and paste it where the object type is the same. Therefore I need to reRender the <a4j:commandLink>-s which are performing the paste action (so it will show on the GUI or not). Simplified example: Problem is that copy links are deep in the tree. How is it possible to reRender on a higher level in the component tree? (very)Simplified example: ... <h:form id="form1"> ... <a4j:commandLink value="Copy" reRender=":paste1, :paste2, :paste3" /> <a4j:commandLink id="paste1" value="Paste" rendered="#{myBean.myHashMap.key}" /> <a4j:outputPanel> <a4j:region renderRegionOnly="true"> <a4j:commandLink value="Copy" reRender=":paste1, :paste2, :paste3" /> <a4j:commandLink id="paste2" value="Paste" rendered="#{myBean.myHashMap.key}" /> </a4j:region> <a4j:outputPanel> <a4j:region renderRegionOnly="true"> <a4j:commandLink value="Copy" reRender=":paste1, :paste2, :paste3" /> <a4j:commandLink id="paste3" value="Paste" rendered="#{myBean.myHashMap.key}" /> </a4j:region> </a4j:outputPanel> </a4j:outputPanel> ... </h:form> Something like that. In practise this differs in that a rich:tree is displayed. Also, there can be multiple instances of the same paste link: object:0::paste3, object:1::paste3. private final String pasteIDs = ":xxPaste, ... , :xyPaste"; According to the RichFaces reference, putting the separator to the beginning of the ID means it is an "absolute" search expression, however this way i get the same result: only the 'local' paste link gets rerendered, the others not. Every copy-paste link pair is encapsulated in <a4j:region renderRegionOnly="true">, because it is necessary for other components to restrict the reRender to that region. Could this be blocking the reRender I want to make? Also I want to rerender exactly those paste links, so no other rerender action is triggered. Hope it is clear what i want to achieve. Any help would be appreciated! Daniel

  • struct method linking

    - by James
    I'm updating some old code that has several POD structs that were getting zero'd out by memset (don't blame me...I didn't write this part). Part of the update changed some of them to classes that use private internal pointers that are now getting wiped out by the memset. So I added a [non-virtual] reset() method to the various structs and refactored the code to call that instead. One particular struct developed an "undefined reference to `blah::reset()'" error. Changing it from a struct to a class fixed the error. Calling nm on the .o file h, the mangled function names for that method look the same (whether it's a class or a struct). I'm using g++ 4.4.1, on Ubuntu. I hate the thought that this might be a compiler/linker bug, but I'm not sure what else it could be. Am I missing some fundamental difference between structs and classes? I thought the only meaningful ones were the public/private defaults and the way everyone thinks about them.

  • mvvm-light: Should we merge Cleanup methods in locator?

    - by mark smith
    Hi there, when creating a new ViewModel within the locator class using the snippet it creates a Cleanup Method but there is already one available from the Main so hence an error.... Should we merge them all?? Or should we be renaming the method to Cleanup[Name of viewmodel] for example. I am a little confused here Another question i would like to ask is regards to the naming conventions. I tried to follow the naming convention used with "MAIN"... hence i have CreateLogin, ClearLogin, Login (non static property for binding) etc etc.. Would it not be better to use CreateLoginViewModel, ClearLoginViewModel etc?? Just curious Thanks

  • feof() in C file handling

    - by Neeraj
    I am reading a binary file byte-by-byte,i need determine that whether or not eof has reached. feof() doesn't works as "eof is set only when a read request for non-existent byte is made". So, I can have my custom check_eof like: if ( fread(&byte,sizeof(byte),1,fp) != 1) { if(feof()) return true; } return false; But the problem is, in case when eof is not reached, my file pointer is moved a byte ahead. So a solution might be to use ftell() and then fseek() to get it to correct position. Another solution might be to buffer the byte ahead in some temporary storage. Any better solutions?

  • How to avoid code duplication for one-off methods with a slightly different signature

    - by Sean
    I am wrapping a number of functions from a vender API in C#. Each of the wrapping functions will fit the pattern: public IEnumerator<IValues> GetAggregateValues(string pointID, DateTime startDate, DateTime endDate, TimeSpan period) { // Validate Data // Break up Requesting Time-Span // Make Requests // Read Results (through another method call } 5 of the 6 requests are aggregate data pulls and have the same signature, so it makes sense to put them in one method and pass the aggregate type to avoid duplication of code. The 6th method however follows the exact same pattern with the same result-set, but is not an aggregate, so no time period is passed to the function (changing the signature). Is there an elegant way to handle this kind of situation without coding a one-off function to handle the non-aggregate request?

  • DB2 Transaction log is full. How to flush / clear it?

    - by Mestika
    Hi, I’m working on a experiment regarding to a course I’m taking about tuning DB2. I’m using the EC2 from Amazon (aws) to conduct the experiment. My problem is, however, that I have to test a non-compression against row-compression in DB2 and to do that I’ve created a bsh file that run those experiments. But when I reach to my compression part I get the error ”Transaction log is full”; and no matter how low I set the inserts for it is complaining about my transaction log. I’ve scouted Google for a day now trying to find some way to flush / clear the log or just get rit of it, i don’t need it. I’ve tried to increase the size but nothing has helped. Please, I hope someone has an answer to solve this frustrating problem Thanks - Mestika

  • Facebook canvas app ASP.NET MVC HttpException: Invalid Model

    - by zznq
    I am working on a Facebook tab application. I am using asp.net MVC 2 with the "official" Microsoft Facebook SDK. Most of my views are working just fine. However, I have one that is causing a huge mess. I am simply returning a List<Tags> to the view and as my ViewModel. This problematic view is simply displaying the list in a foreach loop. Whenever navigate to this view I get a "System.Web.HttpException: Invalid Model" exception. The most puzzling part of all this is that the same code is running without fail on our regular(non-Facebook) app that works just fine with the same code. Any insight into why Facebook and asp.net MVC 2 would be causing this behavior would be much appreciated.

  • Anyone use Distributed VCS in a corporate environment?

    - by Eddie Parker
    I'm curious to hear about people's experiences with distributed version control in a corporate environment. Specifically: Was it difficult to gain adoption? Now that it's in place, is it well liked? What 'model' are you using (hub & spoke? Something else?) Allowing you use hub & spoke, are there any discipline problems with pushing to a central server? I'd like to hear if anyone has non-programmers working within this environment, preferably artists and the like to whom VCS can be a bit daunting. Did it work out for them?

  • Java multithreaded server - each connection returns data. Processing on main thread?

    - by oliwr
    I am writing a client with an integrated server that should wait indefinitely for new connections - and handle each on a Thread. I want to process the received byte array in a system wide available message handler on the main thread. However, currently the processing is obviously done on the client thread. I've looked at Futures, submit() of ExecutorService, but as I create my Client-Connections within the Server, the data would be returned to the Server thread. How can I return it from there onto the main thread (in a synchronized packet store maybe?) to process it without blocking the server? My current implementation looks like this: public class Server extends Thread { private int port; private ExecutorService threadPool; public Server(int port) { this.port = port; // 50 simultaneous connections threadPool = Executors.newFixedThreadPool(50); } public void run() { try{ ServerSocket listener = new ServerSocket(this.port); System.out.println("Listening on Port " + this.port); Socket connection; while(true){ try { connection = listener.accept(); System.out.println("Accepted client " + connection.getInetAddress()); connection.setSoTimeout(4000); ClientHandler conn_c= new ClientHandler(connection); threadPool.execute(conn_c); } catch (IOException e) { System.out.println("IOException on connection: " + e); } } } catch (IOException e) { System.out.println("IOException on socket listen: " + e); e.printStackTrace(); threadPool.shutdown(); } } } class ClientHandler implements Runnable { private Socket connection; ClientHandler(Socket connection) { this.connection=connection; } @Override public void run() { try { // Read data from the InputStream, buffered int count; byte[] buffer = new byte[8192]; InputStream is = connection.getInputStream(); ByteArrayOutputStream out = new ByteArrayOutputStream(); // While there is data in the stream, read it while ((count = is.read(buffer)) > 0) { out.write(buffer, 0, count); } is.close(); out.close(); System.out.println("Disconnect client " + connection.getInetAddress()); connection.close(); // handle the received data MessageHandler.handle(out.toByteArray()); } catch (IOException e) { System.out.println("IOException on socket read: " + e); e.printStackTrace(); } return; } }

  • Zend AMF throwing InvocationTargetException

    Hi, I am trying to make a service call to a php function from flex, through Zend AMF. Most of the functions get called fine, but for one particular function, it throws the following exception: InvocationTargetException:There was an error while invoking the operation. Check your operation inputs or server code and try invoking the operation again. Reason: Fatal error: Call to a member function getInvokeArguments() on a non-object in D:\wamp\www\ZendFramework\library\Zend\Amf\Server.php on line 328 I am not able to debug through this - has anyone faced any issue like this before, or have any ideas how this can be debugged?
