  • Error editing a blob field in ArcGIS Engine

    - by Victor Grigoriu
    I have a GIS layer backed by a MSSQL db. The features on the layer have, say, one field of type esriFieldTypeString and one of type esriFieldTypeBlob. I can edit the string field just fine, but, when I try to edit a blob, StopEditOperation() throws a very generic exception (message: "Error HRESULT E_FAIL has been returned from a call to a COM component.", error code: -2147467259). I couldn't find anything related in the server log. Does anyone have any idea what's going on? IServerContext serverContext = GetServerContext(agsConn, serviceName); ILayer layer = GetILayer(layerName, serverContext); IWorkspace workspace = GetIWorkspace(layer); var feature = GetIFeature(objectId, workspace, layer); var workspaceEdit = (IWorkspaceEdit)workspace; workspaceEdit.StartEditing(false); workspaceEdit.StartEditOperation(); var index = feature.Fields.FindField(featureDetailName); IField field = feature.Fields.get_Field(index); byte[] byteArray = {1, 2, 3}; MemoryBlobStream blob = new MemoryBlobStream(); ((IMemoryBlobStreamVariant)blob).ImportFromVariant(byteArray); if (field.CheckValue(blob)) { feature.set_Value(index, blob); } feature.Store(); workspaceEdit.StopEditOperation(); workspaceEdit.StopEditing(true); serverContext.RemoveAll(); serverContext.ReleaseContext();

  • Why does the proxy generated code create a new class when a MessageContract is in my WCF Service?

    - by DaleyKD
    I have created two WCF Services (Shipping & PDFGenerator). They both, along with my ClientApp, share an assembly named Kyle.Common.Contracts. Within this assembly, I have three classes: namespace Kyle.Common.Contracts { [MessageContract] public class PDFResponse { [MessageHeader] public string fileName { get; set; } [MessageBodyMember] public System.IO.Stream fileStream { get; set; } } [MessageContract] public class PDFRequest { [MessageHeader] public Enums.PDFDocumentNameEnum docType { get; set; } [MessageHeader] public int? pk { get; set; } [MessageHeader] public string[] emailAddress { get; set; } [MessageBodyMember] public Kyle.Common.Contracts.TrackItResult[] trackItResults { get; set; } } [DataContract(Name = "TrackResult", Namespace = "http://kyle")] public class TrackResult { [DataMember] public int SeqNum { get; set; } [DataMember] public int ShipmentID { get; set; } [DataMember] public string StoreNum { get; set; } } } My PDFGenerator ServiceContract looks like: namespace Kyle.WCF.PDFDocs { [ServiceContract(Namespace="http://kyle")] public interface IPDFDocsService { [OperationContract] PDFResponse GeneratePDF(PDFRequest request); [OperationContract] void GeneratePDFAsync(Kyle.Common.Contracts.Enums.PDFDocumentNameEnum docType, int? pk, string[] emailAddress); [OperationContract] Kyle.Common.Contracts.TrackResult[] Test(); } } If I comment out the GeneratePDF stub, the proxy generated by VS2010 realizes that Test returns an array of Kyle.Common.Contracts.TrackResult. However, if I leave GeneratePDF there, the proxy refuses to use Kyle.Common.Contracts.TrackResult, and instead creates a new class, ClientApp.PDFDocServices.TrackResult, and uses that as the return type of Test. Is there a way to force the proxy generator to use Kyle.Common.Contracts.TrackResult whenever I use a MessageContract? Perhaps there's a better method for using a Stream and File Name as return types? I just don't want to have to create a Copy method to copy from ClientApp.PDFDocServices.TrackResult to Kyle.Common.Contracts.TrackResult, since they should be the exact same class. Thanks in advance, Kyle

  • UIButton not firing selector if I draw it using CALayer

    - by Horatiu Paraschiv
    Hi everybody I create this button like this: _myButton = [[UIButton buttonWithType:UIButtonTypeCustom] retain]; DLBadgeLayerDelegate *layerDelegate = [[DLBadgeLayerDelegate alloc] init]; _myButton.frame = CGRectMake(0.0 , 0.0, 100.0, 100.0); [_myButton addTarget:self action:@selector(myButtonTapped:) forControlEvents:UIControlEventTouchUpInside]; _myButton.layer.backgroundColor = [[UIColor redColor] CGColor]; _myButton.center = CGPointMake(10.0, 10.0); [self addSubview:_myButton]; [_myButton release]; The button appears on the screen but if I tap on it nothing happens. If I just create a Rounded rect button instead with no custom drawing on its layer or if I just leave the layer line of code out all works well. Do you have any Idea why do I get this behaviour as I would like to do some custom drawing in the button's layer?

  • Mock versus Implementation. How to share both approaches in a single Test class ?

    - by Arthur Ronald F D Garcia
    Hi, See the following Mock Test by using Spring/Spring-MVC public class OrderTest { // SimpleFormController private OrderController controller; private OrderService service; private MockHttpServletRequest request; @BeforeMethod public void setUp() { request = new MockHttpServletRequest(); request.setMethod("POST"); Integer orderNumber = 421; Order order = new Order(orderNumber); // Set up a Mock service service = createMock(OrderService.class); service.save(order); replay(service); controller = new OrderController(); controller.setService(service); controller.setValidator(new OrderValidator()); request.addParameter("orderNumber", String.valueOf(orderNumber)); } @Test public void successSave() { controller.handleRequest(request, new MockHttpServletResponse()); // Our OrderService has been called by our controller verify(service); } @Test public void failureSave() { // Ops... our orderNumber is required request.removeAllParameters(); ModelAndView mav = controller.handleRequest(request, new MockHttpServletResponse()); BindingResult bindException = (BindingResult) mav.getModel().get(BindingResult.MODEL_KEY_PREFIX + "command"); assertEquals("Our Validator has thrown one FieldError", bindException.getAllErrors(), 1); } } As you can see, i do as proposed by Triple A pattern Arrange (setUp method) Act (controller.handleRequest) Assert (verify and assertEquals) But i would like to test both Mock and Implementation class (OrderService) by using this single Test class. So in order to retrieve my Implementation, i re-write my class as follows @ContextConfiguration(locations="/app.xml") public class OrderTest extends AbstractTestNGSpringContextTests { } So how should i write my single test to Arrange both Mock and Implementation OrderService without change my Test method (sucessSave and failureSave) I am using TestNG, but you can show in JUnit if you want regards,

  • How To: UiBinder + GWT MVP + multiple independent display areas

    - by Prt Yz
    I am using GWT MVP and UiBinder to create an app with a DockLayoutPanel. I want the north and south docks to be static, containing buttons and links. I want to have dynamic views in the center and two different areas of the east dock. As these dynamic areas should be independent of each other, I am setting up different ActivityMapper and ActivityManager's for each dynamic display area; center, east-top, and east-bottom. How can I independently initialize these 3 different display areas when the application is loaded? How can I switch from one Activity to another in one display area without affecting the other areas?

  • WCF Double Hop questions about Security and Binding.

    - by Ken Maglio
    Background information: .Net Website which calls a service (aka external service) facade on an app server in the DMZ. This external service then calls the internal service which is on our internal app server. From there that internal service calls a stored procedure (Linq to SQL Classes), and passes the serialized data back though to the external service, and from there back to the website. We've done this so any communication goes through an external layer (our external app server) and allows interoperability; we access our data just like our clients consuming our services. We've gotten to the point in our development where we have completed the system and it all works, the double hop acts as it should. However now we are working on securing the entire process. We are looking at using TransportWithMessageCredentials. We want to have WS2007HttpBinding for the external for interoperability, but then netTCPBinding for the bridge through the firewall for security and speed. Questions: If we choose WS2007HttpBinding as the external services binding, and netTCPBinding for the internal service is this possible? I know WS-* supports this as does netTCP, however do they play nice when passing credential information like user/pass? If we go to Kerberos, will this impact anything? We may want to do impersonation in the future. If you can when you answer post any reference links about why you're answering the way you are, that would be very helpful to us. Thanks!

    I'll let users register their [email protected] ,,, they enter their members area where they can : 1- send emails ( easy to do) 2- receive emails .. for receiving emails , I'll use a catch all email account , read the email and figure to whom it's sent (username), and then I save it on the database with userid of the username who has registerd ! Do I miss something here ... is it really this simple (if I don't have an email server) ?

  • Is the design notion of layers contrived?

    - by Bruce
    Hi all I'm reading through Eric Evans' awesome work, Domain-Driven Design. However, I can't help feeling that the 'layers' model is contrived. To expand on that statement, it seems as if it tries to shoe-horn various concepts into a specific, neat model, that of layers talking to each other. It seems to me that the layers model is too simplified to actually capture the way that (good) software works. To expand further: Evans says: "Partition a complex program into layers. Develop a design within each layer that is cohesive and that depends only on the layers below. Follow standard architectural patterns to provide loose coupling to the layers above." Maybe I'm misunderstanding what 'depends' means, but as far as I can see, it can either mean a) Class X (in the UI for example) has a reference to a concrete class Y (in the main application) or b) Class X has a reference to a class Y-ish object providing class Y-ish services (ie a reference held as an interface). If it means (a), then this is clearly a bad thing, since it defeats re-using the UI as a front-end to some other application that provides Y-ish functionality. But if it means (b), then how is the UI any more dependent on the application, than the application is dependent on the UI? Both are decoupled from each other as much as they can be while still talking to each other. Evans' layer model of dependencies going one way seems too neat. First, isn't it more accurate to say that each area of the design provides a module that is pretty much an island to itself, and that ideally all communication is through interfaces, in a contract-driven/responsibility-driven paradigm? (ie, the 'dependency only on lower layers' is contrived). Likewise with the domain layer talking to the database - the domain layer is as decoupled (through DAO etc) from the database as the database is from the domain layer. Neither is dependent on the other, both can be swapped out. Second, the idea of a conceptual straight line (as in from one layer to the next) is artificial - isn't there more a network of intercommunicating but separate modules, including external services, utility services and so on, branching off at different angles? Thanks all - hoping that your responses can clarify my understanding on this..

  • Can I use OAuth for a SOAP web service?

    - by Olaseni
    The standard HTTP Authentication for SOAP passed the password etc in cleartext,and I'm looking for an alternative, possibly a key based mechanism to authenticate web services in lieu of the password. OAuth is gaining a lot of popularity; would it be appropriate, and how would I implement it? Or perhaps there are other methods I should use. The project itself is relatively simple, with just a one or two methods to be exposed, but security is of the utmost importance.

  • Issue with CAAnimation and CALayer Transforms

    - by Brian
    I have a CALayer that I want to animate across the screen. I have created two methods: one slide open the layer and one to slide close. These both work by assigning a property to the layer's transform property. Now I want to use a CAKeyFrameAnimation to slide open the layer. I got this working so the layer slides open, but now I can't slide the layer close using my old method. I am trying to figure out why this is. Any help would be great. Code: - (id)init { if( self = [super init] ) { bIsOpen = NO; closeTransform = self.transform; openTransform = CATransform3DMakeTranslation(-235.0, 0.0, 0.0); } return self; } - (void)closeMenu { if( bIsOpen ) { self.transform = closeTransform; bIsOpen = !bIsOpen; } } - (void)openMenu { if( !bIsOpen ) { CAKeyframeAnimation *closeAnimation = [CAKeyframeAnimation animationWithKeyPath:@"transform"]; closeAnimation.duration = 1.0; closeAnimation.removedOnCompletion = NO; closeAnimation.fillMode = kCAFillModeForwards; closeAnimation.values = [NSArray arrayWithObjects:[NSValue valueWithCATransform3D:closeTransform],[NSValue valueWithCATransform3D:openTransform],nil]; closeAnimation.timingFunctions = [NSArray arrayWithObject:[CAMediaTimingFunction functionWithName:kCAMediaTimingFunctionLinear]]; [self addAnimation:closeAnimation forKey:@"transform"]; bIsOpen = !bIsOpen; } }

  • How to implement a bidirectional "mailbox service" over tcp?

    - by igorgatis
    The idea is to allow to peer processes to exchange messages (packets) over tcp as much asynchronously as possible. The way I'd like it to work is each process to have an outbox and an inbox. The send operation is just a push on the outbox. The receive operation is just a pop on the inbox. Underlying protocol would take care of the communication details. Is there a way to implement such mechanism using a single TCP connection? How would that be implemented using BSD sockets and modern OO Socket APIs (like Java or C# socket API)?

  • How do you build a Request-Response service using Asyncore in Python?

    - by Casey
    I have a 3rd-party protocol module (SNMP) that is built on top of asyncore. The asyncore interface is used to process response messages. What is the proper technique to design a client that generate the request-side of the protocol, while the asyncore main loop is running. I can think of two options right now: Use the loop,timeout parameters of asyncore.loop() to allow my client program time to send the appropriate request. Create a client asyncore dispatcher that will be executed in the same asyncore processing loop as the receiver. What is the best option? I'm working on the 2nd solution, cause the protocol API does not give me direct access to the asyncore parameters. Please correct me if I've misunderstood the proper technique for utilizing asyncore.

  • How can I load a Class contained in a website from a DLL referenced by that website???

    - by Morgeh
    Ok so this is alittle bit obscure and I'm not sure its the best way of doing what I'm trying to do but here goes. Basically I have a Presentation Layer Dll in my web site which handles the Model View Presenter classes. The presentation layer also handles login for my website and then calls off to a web service. Currently whenever the presentation layer calls to a model it verifies the users details and if they are invalid it calls to a loginHandler which redirects the user to the login page. However I cannot dynamically load a new istance of the Login Page in my website from within my Presentation layer. I've tried to use reflection to dynamically load the class but Since the method call is in the presentation assembly it is only looking within that assembly while the page I want to load is in the website. heres the reflection code that loads the View: public ILoginView LoadView() { string viewName = ConfigurationManager.AppSettings["LoginView"].ToString(); Type type = Type.GetType(viewName, true); object newInstance = Activator.CreateInstance(type); return newInstance as ILoginView; } Anyone got any suggestions on how to search within the website assembly? Ideal I don't want to tie this implementation into the website specifically as the presentation layer is also used in a WPF application.

  • How do I remove those rotation artefacts from my CATiledLayer?

    - by Felix
    Hello all, I have a CATiledLayer into which I render content in the following method - (void)drawLayer:(CALayer *)layer inContext:(CGContextRef)ctx I used the QuartzDemo code to draw a pattern. This works very well until I apply a rotation transform to the layer's parentLayer (a UIView): rotated: These zigzag artefacts become worse when I start drawing lines and texts into the CATiledLayer. I applied the transform as follows (I also tried using an affine transform on the view itself): self.containerView.layer.transform = CATransform3DMakeRotation(angleRadians, 0.0f, 0.0f, 1.0f); I transform the containerView rather than the layer itself, as I have several layers in that view that I would like to rotate at the same time without changing the relative positions. I did not have problems when rotating UIImageViews in the past. Is there a way that I can rotate the CATiledLayer without these problems? Any help would be greatly appreciated. Yours, Felix

  • Can FAXCOMEXLib and Windows Fax Service send a color fax?

    - by Craig
    We are in the process of testing different options for sending faxes from within our C# code (receiving faxes is not necessary). One of those options is to use FAXCOMEXLib. Without surprise, I've had pretty good success sending out black & white faxes with FAXCOMExLib. But we also have a requirement to support sending color faxes. So I execute the following code (just a snippet): IFaxDocument oFaxDoc = new FaxDocumentClass(); oFaxDoc.Body = @"C:\Test\color_image.jpg"; oFaxDoc.ConnectedSubmit(m_oFaxServer); The image is 24bit color, 1728x2304, 204x196 dpi. For the most part, this process works (with a couple of small quirks) and the fax shows up in my "Windows Fax and Scan" outbox (I'm on Vista). The problem is the image has been dithered to a 1bit black & white image. I assume that what I see in "Windows Fax and Scan" is what is actually transmitted. So is there a way to send a color fax using this technology? Are we missing a configuration option somewhere to make it work?
