  • Interface design pattern / Java / Seam

    - by Walter White
    Hi all, Is this possible somehow? @Name("geolocationService") public interface GeolocationService { @Query("SELECT g FROM Geolocation geolocation INNER JOIN geolocation.deployment deployment WHERE geolocation.ipStart <= INET_ATON(:ipAddress) AND deployment.active = TRUE") Geolocation findByIpAddress(@NamedParameter("ipAddress")final String ipAddress); } public GeolocationAction { @In private GeolocationService geolocationService; @RequestParameter("ipAddress") private String ipAddress; @Out private Geolocation geolocation; public void find() { geolocation = geolocationService.findByIpAddress(ipAddress); } } Is it possible to do this without implementing the interface? What is required to make that work? I want to maintain less and do more. If I can intercept invocations of the geolocationService then I am golden, how would I do that? I don't want it to ever be instantiated, so it will always be null (I don't want the @Name and @In annotations either then). Walter

  • Using Word COM objects in .NET, InlineShapes not copied from template to document

    - by Keith
    Using .NET and the Word Interop I am programmatically creating a new Word doc from a template (.dot) file. There are a few ways to do this but I've chosen to use the AttachedTemplate property, as such: Dim oWord As New Word.Application() oWord.Visible = False Dim oDocuments As Word.Documents = oWord.Documents Dim oDoc As Word.Document = oDocuments.Add() oDoc.AttachedTemplate = sTemplatePath oDoc.UpdateStyles() (I'm choosing the AttachedTemplate means of doing this over the Documents.Add() method because of a memory leak issue I discovered when using Documents.Add() to open from templates.) This works fine EXCEPT when there is an image (represented as an InlineShape) in the template footer. In that case the image does not appear in the resulting document. Specifically the image should appear in the oDoc.Sections.Item(1).Footers.Item(WdHeaderFooterIndex.wdHeaderFooterPrimary).Range.InlineShapes collection but it does not. This is not a problem when using Documents.Add(), however as I said that method is not an option for me. Is there an extra step I have to take to get the images from the template? I already discovered that when using AttachedTemplate I have to explicitly call UpdateStyles() (as you can see in my code snippet) to apply the template styles to the document, whereas that is done automatically when using Documents.Add(). Or maybe there's some crazy workaround? Your help is much appreciated! :)

  • Outlook MAPI session exception when outlook interface is closed

    - by michele
    I'm developing a email sender that retrieve data from a database, build up a MailItem with the Outlook Interop and send it. My email sender is running by a windows service that is notified everytime there's some data to send. I'm logging on the MAPI session of Outlook without problem and everything seems to work. But... when someone open Outlook interface and then close, my service crash at the first attempt i call a SendAndReceive method, with an exception that report that the session is assigned to another thread. I'm googling around for hours and i'm listening to the application_quit event, raised by the interface closing, trying to logoff and logon again to the application...but i'm still falling in the same error. Where am i wrong?Any suggestion? Thank you in advance

  • Programming tips for writing document editors?

    - by Tesserex
    I'm asking this because I'm in the process of writing two such editors for my Mega Man engine, one a tileset editor, and another a level editor. When I say document editor, I mean the superset application type for things like image editors and text editors. All of these share things like toolbars, menu options, and in the case of image editors, and my apps, tool panes. We all know there's tons of advice out there for interface design in these apps, but I'm wondering about programming advice. Specifically, I'm doubting my code designs with the following things: Many menu options toggle various behaviors. What's the proper way to reliably tie the checked state of the option with the status of the behavior? Sometimes it's more complicated, like options being disabled when there's no document loaded. More and more consensus seems to be against using MDI, but how should I control tool panes? For example, I can't figure out how to get the panels to minimize and maximize along with the main window, like Photoshop does. When tool panels are responsible for a particular part of the document, who actually owns that thing? The main window, or the panel class? How do you do communication between the tool panels and the main window? Currently mine is all event based but it seems like there could be a better way. This seems to be a common class of gui application, but I've never seen specific pointers on code design for them. Could you please offer whatever advice or experience you have for writing them?

  • Newly created Document library and columns using webservices are not visible on sharepoint

    - by Royson
    Hi, for creating a columns I worked on this code . and for creating document library Lists listService = new Lists(); listService.PreAuthenticate = true; listService.Credentials = new NetworkCredential(username,password,domain; String url = "http://YourServer/SiteName/"; listService.Url = url @ + /_vti_bin/lists.asmx"; XmlNode ndList = listService.AddList(NewListName, "Description", 101); Both are working successfully. But Problem i am facing is: New Columns and document library are not visible. I tried with comparing Field Value of Both Visible and No-Visible types. Difference i found is : Visible (Created Manually) doesn't contain Version value. were as i am creating have it. Can you help me out in this? EDIT: I checked contents of ndList node, List is created and it is visible on my UI. but on sharepoint it should be listed in 'Document' tab where default 'Shared Documents' library is shown. If i click on 'Documents' then we can also see all lib created by this code. Visible means library displayed under 'Documents' tab

  • slsvcutil.exe Proxy and Interfaces

    - by JPM
    Is it possible when using slsvcutil.exe to generate a proxy through the command line not to have the proxy file output the Interface in an Asynchronous fashion. For example, if I have a function "foo()" on the serverside in the Interface, when I generate the proxy using Slsvcutil.exe, it makes two functions in the interface definition in the proxy named "BeginFoo()" and "EndFoo()". All I want is "Foo()", I don't need the other two methods. Is this possible? I'm using the proxy with Monotouch which is why I need to use Slsvcutil.exe but don't need the Asynchronous methods. Thanks!

  • Not indent the first paragraph of a LaTeX document

    - by Andrew
    In the standard LaTeX article class (and probably others as well), paragraph indentation follows standard American publishing norms of not indenting the first paragraph after a section{} or subsection{}. I've redefined \maketitle in a LaTeX document and put the actual title left-aligned as the last line, fairly close to the actual text (kind of like this) Author Date Title Lorem ipsum dolor sit amet, consectetur adipisicing elit, sed do eiusmod tempor incididunt ut labore et dolore magna aliqua. Ut enim ad minim veniam, quis nostrud exercitation ullamco laboris nisi ut aliquip ex ea commodo consequat. Duis aute irure dolor in reprehenderit in voluptate velit esse cillum dolore eu fugiat nulla pariatur. Excepteur sint occaecat cupidatat non proident, sunt in culpa qui officia deserunt mollit anim id est laborum. Section title Lorem ipsum dolor sit amet, consectetur adipisicing elit, sed do eiusmod tempor incididunt ut labore et dolore magna aliqua. Ut enim ad minim veniam, quis nostrud exercitation ullamco laboris nisi ut aliquip ex ea commodo consequat. Duis aute irure dolor in reprehenderit in voluptate velit esse cillum dolore eu fugiat nulla pariatur. Excepteur sint occaecat cupidatat non proident, sunt in culpa qui officia deserunt mollit anim id est laborum. Since the title is left-aligned and so close to the text, I'd like the first paragraph of the document to not be indented, just like with the headings ... Title Lorem ipsum dolor sit amet, consectetur adipisicing elit, sed do eiusmod tempor incididunt ut labore et dolore magna aliqua. Ut enim ad minim veniam, quis nostrud exercitation ullamco laboris nisi ut aliquip ex ea commodo consequat. Duis aute irure dolor... ... I've attempted to use @afterindentfalse, which is what the section commands use, inside my renewed commands, but it doesn't work. \makeatletter \def\noindentation{\let\@afterindentfalse} \newcommand{\mytitle}[1]{% \vskip 2em {\bf\sffamily\LARGE #1} \noindentation} \renewcommand{\@maketitle}{ \begin{flushleft}{ % Author \@author \par % Date \@date \par % Title \mytitle{\@title} } \end{flushleft} } \makeatother By default the first paragraph in the article class is indented, so this question is applicable whether or not I renew \maketitle. So, what's the best way to automatically not indent the first paragraph of the document? Thanks!

  • Autotesting a network interface

    - by Machado
    Hi All, I'm developing a software component responsible for testing if a network interface has conectivity with the internet. Think of it as the same test the XBOX360 does to inform the user if it's connected with the Live network (just as an example). So far I figured the autotest would run as this: 1) Test the physical network interface (if the cable is conected, has up/downlink, etc...) 2) Test the logical network (has IP address, has DNS, etc...) 3) Connects to the internet (can access google, for example) 4) ??? 5) Profit! (just kidding...) My question relates to step 3: How can I detect, correctly, if my software has connection with the internet ? Is there any fixed IP address to ping ? The problem is that I don't want to rely solely on google.com (or any other well-known address), as those can change in time, and my component will be embbeded on a mobile device, not easy to update. Any suggestions ?

  • Create xml document in java applet.

    - by zproxy
    If I try to create a new xml document in a java applet by this code: http://java.sun.com/j2se/1.4.2/docs/api/javax/xml/parsers/DocumentBuilderFactory.html#newInstance() DocumentBuilderFactory.newInstance(); I will get this error: Java Plug-in 1.6.0_19 Using JRE version 1.6.0_19-b04 Java HotSpot(TM) Client VM javax.xml.parsers.FactoryConfigurationError: Provider <!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Strict//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-strict.dtd"> not found at javax.xml.parsers.DocumentBuilderFactory.newInstance(Unknown Source) I do not care about DTD's. Why is it looking for it? How am I supposed to create a xml document in java applets? How can I make it work? The enclosing html document looks like this: <!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Strict//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-strict.dtd"> <html> <head> <title>Loading...</title> </head> Can some comment this thread? The problem was with the entity resolver, which points to the w3c.org web site. The access to the reference DTDs on this site has been restricted for application use. The solution was to implement my own entity resolver.

  • How to use javascript class from within document ready

    - by Richard
    Hi, I have this countdown script wrapped as an object located in a separate file Then when I want to setup a counter, the timeout function in the countdown class can not find the object again that I have setup within the document ready. I sort of get that everything that is setup in the document ready is convined to that scope, however it is possible to call functions within other document ready´s. Does anyone has a solution on how I could setup multiple counters slash objects. Or do those basic javascript classes have to become plugins This is some sample code on how the class begins function countdown(obj) { this.obj = obj; this.Div = "clock"; this.BackColor = "white"; this.ForeColor = "black"; this.TargetDate = "12/31/2020 5:00 AM"; this.DisplayFormat = "%%D%% Days, %%H%% Hours, %%M%% Minutes, %%S%% Seconds."; this.CountActive = true; this.DisplayStr; this.Calcage = cd_Calcage; this.CountBack = cd_CountBack; this.Setup = cd_Setup; } thanks, Richard

  • State pattern: Why doesn't the context class implement or inherit the State abstract interface/class

    - by Ricket
    I'm reading about the State pattern. I have only just begun, so of course I begin by reading the entire Wikipedia article on it. I noticed that both of the examples in the article have some base abstract class or Java interface for a generic State's methods/functions. Then there are some states which inherit from the base and implement those methods/functions in different ways. Then there's a Context class which has a private member of type State and which, at any time, can be equal to an instance of one of the implementations. That context class also implements the same methods, and passes them onto the current state instance, and then has an additional method to change the state (or depending on design I understand the change of state could be a reaction to one of the implemented methods). Why doesn't this context class specifically "extend" or "implement" the generic State base class/interface?

  • Use continue or Checked Exceptions when checking and processing objects

    - by Johan Pelgrim
    I'm processing, let's say a list of "Document" objects. Before I record the processing of the document successful I first want to check a couple of things. Let's say, the file referring to the document should be present and something in the document should be present. Just two simple checks for the example but think about 8 more checks before I have successfully processed my document. What would have your preference? for (Document document : List<Document> documents) { if (!fileIsPresent(document)) { doSomethingWithThisResult("File is not present"); continue; } if (!isSomethingInTheDocumentPresent(document)) { doSomethingWithThisResult("Something is not in the document"); continue; } doSomethingWithTheSucces(); } Or for (Document document : List<Document> documents) { try { fileIsPresent(document); isSomethingInTheDocumentPresent(document); doSomethingWithTheSucces(); } catch (ProcessingException e) { doSomethingWithTheExceptionalCase(e.getMessage()); } } public boolean fileIsPresent(Document document) throws ProcessingException { ... throw new ProcessingException("File is not present"); } public boolean isSomethingInTheDocumentPresent(Document document) throws ProcessingException { ... throw new ProcessingException("Something is not in the document"); } What is more readable. What is best? Is there even a better approach of doing this (maybe using a design pattern of some sort)? As far as readability goes my preference currently is the Exception variant... What is yours?

  • Objects in interface

    - by Peter Kowalchuk
    I created my own object, PKSurvey. In the interface of the View Controller I can define a pointer to it, then in a method I can alloc it and have an instance. How do I keep the instance beyond the method where it was allocated? I assign values in one method and want to be able to use those values in other methods. Should I allocate it in the viewDidLoad method or should I do it somewhere else? @interface DIrectionalDrillerViewController : UIViewController { PKSurvey *Survey=[PKSurvey new]; ---------------- - (void)viewDidLoad { [Survey new];

  • How to pass interface type/GUID reference to an automation method in Delphi

    - by Alan Clark
    In Delphi you can pass class references around to compare the types of objects, and to instantiate them. Can you do the same with interface references being passed to a COM automation server? For example, you can define a method taking a GUID parameter using the type library editor: function ChildNodesOfType(NodeType: TGUID): IMBNode; safecall; In this function I would like to return automation types that support the interface specified by NodeType, e.g. if Supports(SomeNode, NodeType) then result := SomeNode; But the Supports call always fails, I tried passing in the Guids defined in the type library but none of the different types (Ixxx, Class_xxxx, IId_Ixxxx) seem to work.

  • abstract class MouseAdapter vs. interface

    - by Stefano Borini
    I noted this (it's a java.awt.event class). public abstract class MouseAdapter implements MouseListener, MouseWheelListener, MouseMotionListener { .... } Then you are clearly forced to extend from this adapter public class MouseAdapterImpl extends MouseAdapter {} the class is abstract and implements no methods. Is this a strategy to combine different interfaces into a single "basically interface" ? I assume in java it's not possible to combine different interfaces into a single one without using this approach. In other words, it's not possible to do something like this in java public interface MouseAdapterIface extends MouseListener, MouseWheelListener, MouseMotionListener { } and then eventually public class MouseAdapterImpl implements MouseAdapterIface {} Is my understanding of the point correct ? what about C# ?

  • Liferay Document Management System Workflow

    - by Rajkumar
    I am creating a DMS in Liferay. So far I could upload documents in Liferay in document library. And also i can see documents in document and media portlet. The problem is though status for the document is in pending state, the workflow is not started. Below is my code. Anyone please help. Very urgent. Folder folder = null; // getting folder try { folder = DLAppLocalServiceUtil.getFolder(10181, 0, folderName); System.out.println("getting folder"); } catch(NoSuchFolderException e) { // creating folder System.out.println("creating folder"); try { folder = DLAppLocalServiceUtil.addFolder(userId, 10181, 0, folderName, description, serviceContext); } catch (PortalException e3) { // TODO Auto-generated catch block e3.printStackTrace(); } catch (SystemException e3) { // TODO Auto-generated catch block e3.printStackTrace(); } } catch (PortalException e4) { // TODO Auto-generated catch block e4.printStackTrace(); } catch (SystemException e4) { // TODO Auto-generated catch block e4.printStackTrace(); } // adding file try { System.out.println("New File"); fileEntry = DLAppLocalServiceUtil.addFileEntry(userId, 10181, folder.getFolderId(), sourceFileName, mimeType, title, "testing description", "changeLog", sampleChapter, serviceContext); Map<String, Serializable> workflowContext = new HashMap<String, Serializable>(); workflowContext.put("event",DLSyncConstants.EVENT_CHECK_IN); DLFileEntryLocalServiceUtil.updateStatus(userId, fileEntry.getFileVersion().getFileVersionId(), WorkflowConstants.ACTION_PUBLISH, workflowContext, serviceContext); System.out.println("after entry"+ fileEntry.getFileEntryId()); } catch (DuplicateFileException e) { } catch (PortalException e1) { // TODO Auto-generated catch block e1.printStackTrace(); } catch (SystemException e1) { // TODO Auto-generated catch block e1.printStackTrace(); } } catch (PortalException e) { // TODO Auto-generated catch block e.printStackTrace(); } catch (SystemException e) { // TODO Auto-generated catch block e.printStackTrace(); } } return fileEntry.getFileEntryId(); } I have even used WorkflowHandlerRegistryUtil.startWorkflowInstance(companyId, userId, fileEntry.getClass().getName(), fileEntry.getClassPK, fileEntry, serviceContext); But still i have the same problem

  • Class variable defined at @implementation rather than @interface?

    - by bitcruncher
    Hello. I'm new to Objective-C, but I am curious about something that I haven't really seen addressed anywhere else. Could anyone tell me what is the difference between a private variable that is declared at the @interface block versus a variable that is declared within the @implementation block outside of the class methods, i.e: @interface Someclass : NSObject { NSString *forExample; } @end vs. @implementation Someclass NSString *anotherExample; -(void)methodsAndSuch {} @end It seems both variables ( forExample, anotherExample ) are equally accessible throughout the class and I can't really find a difference in their behaviour. Is the second form also called an instance variable?

  • jQuery - iGoogle style interface

    - by samhamilton
    Hi all, I'm currently working on developing a customizable website layout using jQuery, so I can drag, drop, add and remove blocks of content... much like the iGoogle interface. I have my blocks dragging and dropping working with 3 columns of content My question is to do with adding and removing blocks If I use hide(), I can simply hide and show the blocks. If I use remove, I would have to append the list of blocks to load in a new block into a column. I'm not sure which is the best approach to take. I'd be grateful for any advice on best practise, i.e. to hide() or remove() and any other advice on building this kind of interface. Thank, Sam.

  • Does the "Supporting Multiple Screens" document contradict itself?

    - by Neil Traft
    In the Supporting Multiple Screens document in the Android Dev Guide, some example screen configurations are given. One of them states that the small-ldpi designation is given to QVGA (240x320) screens with a physical size of 2.6"-3.0". According to this DPI calculator, a 2.8" QVGA display equates to 143 dpi. However, further down the page the document explicitly states that all screens over 140 dpi are considered "medium" density. So which is it, ldpi or mdpi? Is this a mistake? Does anyone know what the HTC Tattoo or similar device actually reports? I don't have access to any devices like this. Also, with the recent publishing of this document, I'm glad to see we finally have an explicit statement of the exact DPI ranges of the three density categories. But why haven't we been given the same for the small, medium, and large screen size categories? I'd like to know the exact ranges for all these. Thanks in advance for your help!
