  • How to parse an XML string in TDI

    - by ongle
    I am new to TDI. I have a TDI assembly line that calls a web service (ibmdi.InvokeSoapWS) which returns the result as a string in the work attribute 'xmlString'. I then have an AttributeMap that attempts to parse the xml and extract a value (the node it seeks is a few nodes deep). var parser = system.getParser('ibmdi.SOAP'); var xmlString = work.getString('xmlString'); var entity = parser.parseRequest(xmlString); task.dump(entity); The trouble is, the parsed object does not contain an accurate representation of the XML. It contains only two attributes, the first is correctly the first node following the soap body (e.g., ns0:SomeNodeReply), the second being a node inside the first (e.g., ns0:DetailCount). And as far as I can determine, both attributes are just strings so I cannot recurse into the object graph. Below is a sample soap reply: <?xml version="1.0" encoding="utf-8"?> <SOAP-ENV:Envelope xmlns:SOAP-ENV="http://schemas.xmlsoap.org/soap/envelope/"> <SOAP-ENV:Body> <ns0:SomeNodeReply xmlns:ns0="http://xmlns.example.com/unique/default/namespace/1136581686664"> <ns0:Status> <ns0:StatusCD>000</ns0:StatusCD> <ns0:StatusDesc /> </ns0:Status> <ns0:DetailCount>1</ns0:DetailCount> <ns0:SomeDetail> <ns0:CodeA>Foo</ns0:CodeA> <ns0:CodeB>Bar</ns0:CodeB> </ns0:SomeDetail> </ns0:SomeNodeReply> </SOAP-ENV:Body> </SOAP-ENV:Envelope> And below is a sample dump of the parsed string: 19:03:23 CTGDIS003I *** Start dumping Entry 19:03:23 Operation: generic 19:03:23 Entry attributes: 19:03:23 SOAP_CALL (replace): 'ns0:SomeNodeReply' 19:03:23 ns0:DetailCount(replace): '1' 19:03:23 CTGDIS004I *** Finished dumping Entry All I really need to do is be able to parse out a value that may or may not be there, depending on the value of another node (e.g., DetailCount == 1, get CodeA otherwise return empty string). I am open to changing anything about how this works if I can extract the data into the work Entry.

  • How do I update with a newly-created detached entity using NHibernate?

    - by Daniel T.
    Explanation: Let's say I have an object graph that's nested several levels deep and each entity has a bi-directional relationship with each other. A -> B -> C -> D -> E Or in other words, A has a collection of B and B has a reference back to A, and B has a collection of C and C has a reference back to B, etc... Now let's say I want to edit some data for an instance ofC. In Winforms, I would use something like this: var instanceOfC; using (var session = SessionFactory.OpenSession()) { // get the instance of C with Id = 3 instanceOfC = session.Linq<C>().Where(x => x.Id == 3); } SendToUIAndLetUserUpdateData(instanceOfC); using (var session = SessionFactory.OpenSession()) { // re-attach the detached entity and update it session.Update(instanceOfC); } In plain English, we grab a persistent instance out of the database, detach it, give it to the UI layer for editing, then re-attach it and save it back to the database. Problem: This works fine for Winform applications because we're using the same entity all throughout, the only difference being that it goes from persistent to detached to persistent again. The problem occurs when I'm using a web service and a browser, sending over JSON data. In this case, the data that comes back is no longer a detached entity, but rather a transient one that just happens to have the same ID as the persistent one. If I use this entity to update, it will wipe out the relationship to B and D unless I sent the entire object graph over to the UI and got it back in one piece. Question: My question is, how do I serialize detached entities over the web, receive them back, and save them, while preserving any relationships that I didn't explicitly change? I know about ISession.SaveOrUpdateCopy and ISession.Merge() (they seem to do the same thing?), but this will still wipe out the relationships if I don't explicitly set them. I could copy the fields from the transient entity to the persistent entity one by one, but this doesn't work too well when it comes to relationships and I'd have to handle version comparisons manually.

  • Converting contents of HtmlTextWriter to a string

    - by Tony_Henrich
    I have a third party tool that creates an img tag through code using HtmlTextWriter's RenderBeginTag, RenderEndTag & AddAttribute methods. I want to get the resulting HTML into a string. I tried the reflection method mentioned here but I get a error "Unable to cast object of type 'System.Web.HttpWriter' to type 'System.IO.StringWriter". The InnerWriter type of the HtmlTextWriter is of type HttpWriter. Any ideas on how to copy the output html into a string?

  • How to process signals in a Qt subclass?

    - by Jen
    How do I process a signal of in a subclass? Let's say my subclass is derived from QTextEdit and is interested in the signal textChanged. It seems silly to connect an object to itself, I should be able to simply override the textChange method -- but it isn't virtual. What is the accepted way to do this?

So far I have this: int number = 5; cppstring.append((char*)&number, 4); It works fine on a x86 system with Windows, but some people are saying its not cross-platform and is unsafe. What is the preferred method to do this?

  • Unit testing MVC.net Redirection

    - by Dan
    How do I Unit Test a MVC redirection? public ActionResult Create(Product product) { _productTask.Save(product); return RedirectToAction("Success"); } public ActionResult Success() { return View(); } Is Ayende's approach still the best way to go, with preview 5: public static void RenderView(this Controller self, string action) { typeof(Controller).GetMethod("RenderView").Invoke(self,new object[] { action} ); } Seems odd to have to do this, especially as the MVC team have said they are writing the framework to be testable.

  • View list of all JavaScript variables in Google Chrome Console

    - by GRboss
    Hello everyone. In Firebug the DOM tab shows a list of all your public variables and objects. In Chrome's console you have to type the name of the public variable or object you want to explore. Is there a way - or at least a command - for Chrome's console to display a list all the public variables and objects? It will save a lot of typing. Thank you all Stefanos

  • Best practices for displaying large number of images as thumbnails in c#

    - by andySF
    I got to a point where it's very difficult to get answers by debugging and tracing object, so i need some help. What I'm trying to do: A history form for my screen capture pet project. The history must list all images as thumbnails (ex: picasa). What I've done: I created a HistoryItem:UserControl. This history item has a few buttons, a check box, a label and a picture box. The buttons are for delete/edit/copy image. The check box is used for selecting one or more images and the label is for some info text. The picture box is getting the image from a public property that is a path and a method creates a proportional thumbnail to display it when the control has been loaded. This user control has two public events. One for deleting the image and one for bubbling the events for mouse enter and mouse leave trough all controls. For this I use EventBroadcastProvider. The bubbling is useful because wherever I move the mouse over the control, the buttons appear. The dispose method has been extended and I manually remove the events. All images are loaded by looping a xml file that contains the path of all images. For each image in this XML I create a new HitoryItem that is added (after a little coding to sort and limit the amount of images loaded) to a flow layout panel. The problem: When I lunch the history form, and the flow layout panel is populated with my HistoryItem custom control, my memory usage increases drastically.From 14Mb to around 100MB with 100 images loaded. By closing the history form and disposing whatever I could dispose and even trying to call GC.Collect() the memory increase remain. I search for any object that could not be disposed properly like an image or event but wherever I used them they are disposed. The problem seams to be from multiple sources. One is that the events for bubbling are not disposing properly, and the other is from the picture box itself. All of this i could see by commenting all the code to a limited version when only the custom control without any image processing and even events is loaded. Without the events the memory consumption is reduced by axiomatically 20%. So my real question is if this logic, flow layout panels and custom controls with picture boxes, is the best solution for displaying large amounts of images as thumbnails. Thank you!

  • Effect of 'myObj = [[[[MyClass alloc] init] autorelease] retain];'?

    - by filipe
    I've just downloaded the Facebook iOS SDK and I noticed that in the sample code that comes with the SDK whenever it creates an instance of the Facebook class it does it like this: _facebook = [[[[Facebook alloc] init] autorelease] retain]; where _facebook is a member variable of the calling object (i.e. not a local variable). Can anyone explain exactly what's the point of autoreleasing and then retaining it?

  • Weird behaviour of Calendar and DateFormat

    - by Nejc
    I encountered really strange behaviour when constructing a Calendar object and then formating it in a particular style. Let the code do the talking: public class Test { public static void main(String[] args) { SimpleDateFormat frmt = new SimpleDateFormat(); frmt.applyPattern("yyyy-MM-dd"); GregorianCalendar date = new GregorianCalendar(2012,1,1); System.out.println(frmt.format(date.getTime())); } } The output is: 2012-02-01 The expected output is of course: 2012-01-01 What am I doing wrong?

  • Transferring binary data through a SOAP webservice? C# / .NET

    - by Jason
    I have a webservice that returns the binary array of an object. Is there an easier way to transfer this with SOAP or does it need to be contained in XML? It's working, but I had to increase the send and receive buffer to a large value. How much is too much? Transferring binary in XML as an array seems really inefficient, but I can't see any way to add a binary attachment using .NET.

  • Which process retrieves the silverlight xap file?

    We're using silverlight on our SharePoint site. When someone navigates to the page containing the silverlight object, they are prompted for credentials. Other pages work fine. I'm wondering if the client is trying to retrive the xap file (which is in a location the process hosting the web application has access to, but not the user). Is the xap file retrievd by the IIS process or the client?

  • ActionResult - Service

    - by cem
    I bored, writing same code for service and ui. Then i tried to write a converter for simple actions. This converter, converting Service Results to MVC result, seems like good solution for me but anyway i think this gonna opposite MVC pattern. So here, I need help, what you think about algorithm - is this good or not? Thanks ServiceResult - Base: public abstract class ServiceResult { public static NoPermissionResult Permission() { return new NoPermissionResult(); } public static SuccessResult Success() { return new SuccessResult(); } public static SuccessResult<T> Success<T>(T result) { return new SuccessResult<T>(result); } protected ServiceResult(ServiceResultType serviceResultType) { _resultType = serviceResultType; } private readonly ServiceResultType _resultType; public ServiceResultType ResultType { get { return _resultType; } } } public class SuccessResult<T> : ServiceResult { public SuccessResult(T result) : base(ServiceResultType.Success) { _result = result; } private readonly T _result; public T Result { get { return _result; } } } public class SuccessResult : SuccessResult<object> { public SuccessResult() : this(null) { } public SuccessResult(object o) : base(o) { } } Service - eg. ForumService: public ServiceResult Delete(IVUser user, int id) { Forum forum = Repository.GetDelete(id); if (!Permission.CanDelete(user, forum)) { return ServiceResult.Permission(); } Repository.Delete(forum); return ServiceResult.Success(); } Controller: public class BaseController { public ActionResult GetResult(ServiceResult result) { switch (result.ResultType) { case ServiceResultType.Success: var successResult = (SuccessResult)result; return View(successResult.Result); break; case ServiceResultType.NoPermission: return View("Error"); break; default: return View(); break; } } } [HandleError] public class ForumsController : BaseController { [ValidateAntiForgeryToken] [Transaction] [AcceptVerbs(HttpVerbs.Post)] public ActionResult Delete(int id) { ServiceResult result = ForumService.Delete(WebUser.Current, id); /* Custom result */ if (result.ResultType == ServiceResultType.Success) { TempData[ControllerEnums.GlobalViewDataProperty.PageMessage.ToString()] = "The forum was successfully deleted."; return this.RedirectToAction(ec => Index()); } /* Custom result */ /* Execute Permission result etc. */ TempData[ControllerEnums.GlobalViewDataProperty.PageMessage.ToString()] = "A problem was encountered preventing the forum from being deleted. " + "Another item likely depends on this forum."; return GetResult(result); } }
