There are a variety of tools available to help you and Support diagnose SOA Suite issues in 11g but it can be confusing as to which tool is appropriate for a particular situation and what their relationships are. This blog post will introduce the various tools and attempt to clarify what each is for and how they are related. Let's first list the tools we'll be addressing: RDA: Remote Diagnostic Agent DFW: Diagnostic Framework Selective Tracing DMS: Dynamic Monitoring Service ODL: Oracle Diagnostic Logging ADR: Automatic Diagnostics Repository ADRCI: Automatic Diagnostics Repository Command Interpreter WLDF: WebLogic Diagnostic Framework This overview is not mean to be a comprehensive guide on using all of these tools, however, extensive reference materials are included that will provide many more details on their execution. Another point to note is that all of these tools are applicable for Fusion Middleware as a whole but specific products may or may not have implemented features to leverage them. A couple of the tools have a WebLogic Scripting Tool or 'WLST' interface. WLST is a command interface for executing pre-built functions and custom scripts against a domain. A detailed WLST tutorial is beyond the scope of this post but you can find general information here. There are more specific resources in the below sections.In this post when we refer to 'Enterprise Manager' or 'EM' we are referring to Enterprise Manager Fusion Middleware Control. read the full blog post here.

For access to the Oracle demo systems please visit OPN and talk to your Partner Expert DSS is pleased to announce the availability of the demo “Business Driven Development“. This innovative demonstration uses a case-study approach to show business users how they can easily streamline their Business Processes - delivering greater efficiency, agility, visibility and collaboration with Oracle BPM and WebCenter. The BDD demonstration uses a case study-based approach to highlight a business problem at a fictional company, Avitek Corporation, and uses Oracle BPM and Oracle WebCenter to solve the business problem. This holistic approach has specifically been used to appeal to a non-technical business analyst user. This demo is NOT focused on product features, but aims to guide users through a complete BPM lifecycle. The scenario is based on improving a simple order process (scenario details are in the demo script). Avitek Corporation is sufferinng from a manual email-driven ordering process. Sales reps don’t know where the customer orders are stuck (no visibility) and finance users are unable to manually approve every order (no automation). There are several areas where this process can be improved with Business Process Management technology. This demo shows how improving following areas will ignificantly help resolve the business problems Avitek Corporation is facing. Areas for improvement include: Utilizing BPM for process management, rather than an unregulated, email-based process. Utilizing automated services, rather than requiring a human to key into a system. For example, Finance checking the customer’s credit rating is something that could be automated. Centralizing business rules that can be integrated into a business process, rather than requiring a human to process them. For example, Finance must determine when orders can be automatically approved. Provide insight and visibility into the process. For example, Sales Rep needs to know the status of their customer’s orders. The BDD Demo uses the following products.

These new, reusable usability solutions and best-practices, which will join the Oracle dashboard patterns and guidelines that are already available online, are used by Oracle to artfully bring to life a new standard in the user experience, or UX, of enterprise applications. Now, the Oracle applications development community can benefit from the science behind the Oracle Fusion Applications user experience, too. These Oracle Fusion Applications UX Design Patterns, or blueprints, enable Oracle applications developers and system implementers everywhere to leverage professional usability insight when: tailoring an Oracle Fusion application, creating coexistence solutions that existing users will be delighted with, thus enabling graceful user transitions to Oracle Fusion Applications down the road, or designing exciting, new, highly usable applications in the cloud or on-premise. Based on the Oracle Application Development Framework (ADF) components, the Oracle Fusion Applications patterns and guidelines are proven with real users and in the Applications UX usability labs, so you can get right to work coding productivity-enhancing designs that provide an advantage for your entire business. What’s the best way to get started? We’ve made that easy, too. The Design Filter Tool (DeFT) selects the best pattern for your user type and task. Simply adapt your selection for your own task flow and content, and you’re on your way to a really great applications user experience. More Oracle applications design patterns and training are coming your way in the future. To provide feedback on the sets that are currently available, let me know in the comments!

  • Is it possible to force the WCF test client to accept a self-signed certificate?

    - by Lawrence Johnston
    I have a WCF web service running in IIS 7 using a self-signed certificate (it's a proof of concept to make sure this is the route I want to go). It's required to use SSL. Is it possible to use the WCF Test Client to debug this service without needing a non-self-signed certificate?

  • Model validation with enumerable properties in Asp.net MVC2 RTM

    - by Robert Koritnik
    I'm using DataAnnotations attributes to validate my model objects. My model class looks similar to this: public class MyModel { [Required] public string Title { get; set; } [Required] public List<User> Editors { get; set; } } public class User { public int Id { get; set; } [Required] public string FullName { get; set; } [Required] [DataType(DataType.Email)] public string Email { get; set; } } My controller action looks like: public ActionResult NewItem(MyModel data) { //... } User is presented with a view that has a form with: a text box with dummy name where users enter user's names. For each user they enter, there's a client script coupled with ajax that creates an <input type="hidden" name="data.Editors[0].Id" value="userId" /> for each user entered (enumeration index is therefore not always 0 as written here), so default model binder is able to consume and bind the form without any problems. a text box where users enter the title Since I'm using Asp.net MVC 2 RTM which does model validation instead of input validation I don't know how to avoid validation errors. The thing is I have to use BindAttribute on my controller action. I would have to either provide a white or a black list of properties. It's always a better practice to provide a white list. It's also more future proof. The problem My form works fine, but I get validation errors about user's FullName and Email properties since they are not provided. I also shouldn't feed them to the client (via ajax when user enters user data), because email is personal contact data and is not shared between users. If there was just a single user reference on MyModel I would write [Bind(Include = "Title, Editor.Id")] But I have an enumeration of them. How do I provide Bind white list to work with my model?

  • Handle URI hacking gracefully in ASP.NET

    - by asbjornu
    I've written an application that handles most exceptions gracefully, with the page's design intact and a pretty error message. My application catches them all in the Page_Error event and there adds the exception to HttpContext.Curent.Context.Items and then does a Server.Transfer to an Error.aspx page. I find this to be the only viable solution in ASP.NET as there seems to be no other way to do it in a centralized and generic manner. I also handle the Application_Error and there I do some inspection on the exception that occurred to find out if I can handle it gracefully or not. Exceptions I've found I can handle gracefully are such that are thrown after someone hacking the URI to contain characters the .NET framework considers dangerous or basically just illegal at the file system level. Such URIs can look like e.g.: http://exmample.com/"illegal" http://example.com/illegal"/ http://example.com/illegal / (notice the space before the slash at the end of the last URI). I'd like these URIs to respond with a "404 Not Found" and a friendly message as well as not causing any error report to be sent to avoid DDOS attack vectors and such. I have, however, not found an elegant way to catch these types of errors. What I do now is inspect the exception.TargetSite.Name property, and if it's equal to CheckInvalidPathChars, ValidatePath or CheckSuspiciousPhysicalPath, I consider it a "path validation exception" and respond with a 404. This seems like a hack, though. First, the list of method names is probably not complete in any way and second, there's the possibility that these method names gets replaced or renamed down the line which will cause my code to break. Does anyone have an idea how I can handle this less hard-coded and much more future-proof way? PS: I'm using System.Web.Routing in my application to have clean and sensible URIs, if that is of any importance to any given solution.

    When hosting WPF user controls within a WinForms MDI app there is a drawing issue when you have multiple forms that overlap each other that causes very distinct visual artifacts. These artifacts are mostly visible after dragging one child form over another one that also hosts WPF content or by allowing the edges of the child form to be clipped by the main MDI parent when dragging it around. After the drag and drop of the child form is completed the artifacts stay around gernally but I've found that setting focus to a different application's window and then refocusing back on to my application window that it is redrawn and all is good again until the child forms are moved once again. Please see the image below which demonstrates the problem. Since many at Microsoft insist that the WinForms MDI is already a complete solution for MDI even when dealing with WPF I find it hard to believe any of them have ever actually tried creating a mostly WPF app that utilizes WinForms MDI otherwise it would be hard to recommend while keeping a straignt face. I'm hoping to either come up with proof that this solution truly is not acceptable or possibly find a way to overcome this and a few other specific issues.

  • Confusion about Kerberos, delegation and SPNs.

    - by Vilx-
    I'm trying to write a proof-of-concept application that performs Kerberos delegation. I've written all the code, and it seems to working (I'm authenticating fine), but the resulting security context doesn't have the ISC_REQ_DELEGATE flag set. So I'm thinking that maybe one of the endpoints (client or server) is forbidden to delegate. However I'm not authenticating against an SPN. Just one domain user against another domain user. As the SPN for InitializeSecurityContext() I'm passing "[email protected]" (which is the user account under which the server application is running). As I understand, domain users have delegation enabled by default. Anyway, I asked the admin to check, and the "account is sensitive and cannot be delegated" checkbox is off. I know that if my server was running as a NETWORK SERVICE and I used an SPN to connect to it, then I'd need the computer account in AD to have the "Trust computer for delegation" checkbox checked (off by default), but... this is not the case, right? Or is it? Also - when the checkbox in the computer account is set, do the changes take place immediately, or must I reboot the server PC or wait for a while?

  • Application/Server dependency mapping

    - by David Stratton
    I'm just curious as to whether such as tool exists (free, open source, or commercial but for a reasonable price) before I build it myself. We're looking for a simple solution to simplify taking web apps online and offline when a server is undergoing maintenance. The idea is that we be able to mark a server as unavailable, and then mark all dependent (direct and indirect) as offline. Our first proof-of-concept is running, and we created an aspx page that lists various applications that have an App_Offline.html file with a friendly "Down for Maintenance" message in a GridView. In the GridView, each app has a LinkButton that, when clicked, either renames the App_Offline.htm to App_Offline.html or vice-versa to take the app online and offline. The next step is to set up all of our dependencies. For example, our store locater would be dependent on our web services, which in turn are dependent on our SQL Server. (that's a simple example. We can easily have several layers, or one app dependent on multiple servers, etc.) In this example, if the SQL server goes down, we would need to drill down recursively to find all apps that depend on it, and then turn them off and on by renaming the App_Offline file appropriately. I realize this will be relatively simple to build, but could be complex to manage. I'm sure we're not the first team to think of this concept, and I'm wondering if there are any open source tools, or if any of you have done something similar and can help us avoid pitfalls. Edit - Update I found the category of software I'm looking for. it's called CMDB - (Configuration Management Database), and it's generally more of a Network Admin type tool than a developer tool. I found some open source products in this category, but none written in .NET. I had considered moving this question to ServerFault.com when I realized I was looking for a netowrk Admin type tool, but since I'm looking for code and a modifiable solution I'll keep the question here.

  • Web-based clients vs thick/rich clients?

    - by rudolfv
    My company is a software solutions provider to a major telecommunications company. The environment is currently IBM WebSphere-based with front-end IBM Portal servers talking to a cluster of back-end WebSphere Application Servers providing EJB services. Some of the portlets use our own home-grown MVC-pattern and some are written in JSF. Recently we did a proof-of-concept rich/thick-client application that communicates directly with the EJB's on the back-end servers. It was written in NetBeans Platform and uses the WebSphere application client library to establish communication with the EJB's. The really painful bit was getting the client to use secure JAAS/SSL communications. But, after that was resolved, we've found that the rich client has a number of advantages over the web-based portal client applications we've become accustomed to: Enormous performance advantage (CORBA vs. HTTP, cut out the Portal Server middle man) Development is simplified and faster due to use of NetBeans' visual designer and Swing's generally robust architecture The debug cycle is shortened by not having to deploy your client application to a test server No mishmash of technologies as with web-based development (Struts, JSF, JQuery, HTML, JSTL etc., etc.) After enduring the pain of web-based development (even JSF) for a while now, I've come to the following conclusion: Rich clients aren't right for every situation, but when you're developing an in-house intranet-based solution, then you'd be crazy not to consider NetBeans Platform or Eclipse RCP. Any comments/experiences with rich clients vs. web clients?

  • How do you prove your cleverness and programming skills?

    - by Sebi
    Lately, there were a lot of questions related to career planning and how to decide which languages to learn, how to learn new languages and so on. But I was thinking about a way, how do you will proof later that you're really learned something. Ok you can mentione it in your application for a job or in the interview, but by just stating that I was learning e.g. C++ at home, I don't think this will really be very sucessful. So some suggested to create something (homepage, application, whatsoever) to prove that you also can use these skills in practice. But still I'm not really sure if this will provide any benefit, because it would require a very special project to show all your skills and I don't think you can easily invent such a project (that sould also be useful). Others suggested to solve for example the Project Euler questions but still I'm not sure how this will be useful in career-planning. Are you going to mention at your job interview that you solved all this question in the company's favorite programming language?? :D I can't imagine. The reason why I'm asking is that I have some spare time and I would really like to learn some new programming languages (C++ and/or Python if this matters) and I'm looking for a smart way to do is while concurrently assure that it will be useful in my future career. (there are 3-4 companies id like to try to get a job andIi know all of them are using mainly C++/Pyhton...)

  • Getting started with Spring 3 Web MVC - Setting everything up

    - by user126379
    Hi, I'm trying to get started with JAVA/Eclipse/Spring MVC but can't seem to find a "dummies" or "step-by-step" guide for setting everything up and creating the simplest proof-of-concept application. I found http://static.springsource.org/docs/...-step-by-step/ but there seem to be differences between Spring 2.5 and Spring 3 so i'm looking for something for Spring 3. Also, the tutorial for Spring 2.5 focuses on building the application usign Ant - This i will certainly be doing for releasing but when working within Eclipse i want to have set up the project so that i can use breakpoints/debugging and this is not covered at all. I've downloaded Eclipse, Tomcat and the Spring 3 Framework but that's about it and within the downloaded Spring Framework documentation it states: 2.3 New getting started tutorial There is now a new getting started tutorial for developing a basic Spring 3.0 MVC web application. This tutorial is a separate document that can be found at the Spring Documentation page However, i can't seem to find such a tutorial on the linked page. My main problem at the moment, as seems to be the case for many people trying to get started with Spring, is that i can't seem to get everything set up. I've got a copy of Expert Spring MVC and Web Flow and i've also found this tutorial but i don't know if the setups they describe are still relevant and whether they will allow debugging. Can anyone please give some direction? Thanks

  • Using Unicode in fancyvrb’s VerbatimOut

    - by Konrad Rudolph
    Problem VerbatimOut from the “fancyvrb” package doesn’t play nicely with UTF-8 characters. Minimal working example: \documentclass{minimal} \usepackage[utf8]{inputenc} \usepackage[T1]{fontenc} \usepackage{fancyvrb} \begin{document} \begin{VerbatimOut}{\jobname.test} é \end{VerbatimOut} \input{\jobname.test} \end{document} Error message When compiled using pdflatex mini, this gives the error File ended while scanning use of \UTFviii@three@octets. A different error occurs when the sole occurrence of é above is replaced by something else, e.g. é */: Package inputenc Error: Unicode char \u8:### not set up for use with LaTeX. – indicating that in this case, LaTeX succeeds in reading a multi-byte UTF-8 character, but not knowing what to do with it (i.e. it’s the wrong character). In fact, when I open the produced .test file manually, it contains the character é, but in Latin-1 encoding! Proof: when I open the files in a hex editor, I get the following: Original file: C3 A9 (corresponds to LATIN SMALL LETTER E WITH ACUTE in UTF-8) Written file: E9 (corresponds to é in Latin-1) Question How to set VerbatimOut up correctly? filecontents* (from “filecontents”) shows that it can work. Unfortunately, I don’t understand either code so I cannot fix fancyvrb’s code by replicating the logic from filecontents manually. I also cannot use filecontents* instead of VerbatimOut because the former doesn’t work within a \newenvironment, while the latter does. (Oh, by the way: vanilla Verbatim instead of VerbatimOut also works as expected. The error seems to occur when writing the file, not when reading the verbatim input)

  • Model validation with enumerations

    - by Robert Koritnik
    I'm using DataAnnotations attributes to validate my model objects. My model class looks similar to this: public class MyModel { [Required] public string Title { get; set; } [Required] public List<User> Editors { get; set; } } public class User { public int Id { get; set; } [Required] public string FullName { get; set; } [Required] [DataType(DataType.Email)] public string Email { get; set; } } My controller action looks like: public ActionResult NewItem(MyModel data) { //... } User is presented with a view that has a form with: a text box with dummy name where users enter user's names. For each user they enter, there's a client script coupled with ajax that creates an <input type="hidden" name="data.Editors[0].Id" value="userId" /> for each user entered (enumeration index is therefore not always 0 as written here), so default model binder is able to consume and bind the form without any problems. a text box where users enter the title Since I'm using Asp.net MVC 2 RTM which does model validation instead of input validation I don't know how to avoid validation errors. The thing is I have to use BindAttribute on my controller action. I would have to either provide a white or a black list of properties. It's always a better practice to provide a white list. It's also more future proof. The problem My form works fine, but I get validation errors about user's FullName and Email properties since they are not provided. I also shouldn't feed them to the client (via ajax when user enters user data), because email is personal contact data and is not shared between users. If there was just a single user reference on MyModel I would write [Bind(Include = "Title, Editor.Id")] But I have an enumeration of them. How do I provide Bind white list to work with my model?

  • Did I find a bug in WriteableBitmap when using string literals

    - by liserdarts
    For performance reasons I'm converting a large list of images into a single image. This code does exactly what I want. Private Function FlattenControl(Control As UIElement) As Image Control.Measure(New Size(1000, 1000)) Control.Arrange(New Rect(0, 0, 1000, 1000)) Dim ImgSource As New Imaging.WriteableBitmap(1000, 1000) ImgSource.Render(Control, New TranslateTransform) ImgSource.Invalidate Dim Img As New Image Img.Source = ImgSource Return Img End Function I can add all the images into a canvas pass the canvas to this function and I get back one image. My code to load all the images looks like this. Public Function BuildTextures(Layer As GLEED2D.Layer) As FrameworkElement Dim Container As New Canvas For Each Item In Layer.Items If TypeOf Item Is GLEED2D.TextureItem Then Dim Texture = CType(Item, GLEED2D.TextureItem) Dim Url As New Uri(Texture.texture_filename, UriKind.Relative) Dim Img As New Image Img.Source = New Imaging.BitmapImage(Url) Container.Children.Add(Img) End If Next Return FlattenControl(Container) End Function The GLEED2D.Layer and GLEED2D.TextureItem classes are from the free level editor GLEED2D (http://www.gleed2d.de/). The texture_filename on every TextureItem is "Images/tree_clipart_pine_tree.png" This works just fine, but it's just a proof of concept. What I really need to do (among other things) is have the path to the image hard coded. If I replace Texture.texture_filename in the code above with the string literal "Images/tree_clipart_pine_tree.png" the images do not appear in the final merged image. I can add a breakpoint and see that the WriteableBitmap has all of it's pixels as 0 after the call to Invalidate. I have no idea how this could cause any sort of difference, but it gets stranger. If I remove the call to FlattenControl and just return the Canvas instead, the images are visible. It's only when I use the string literal with the WriableBitmap that the images do not appear. I promise you that the value in the texture_filename property is exactly "Images/tree_clipart_pine_tree.png". I'm using Silverlight 3 and I've also reproduced this in Silverlight 4. Any ideas?

  • Disable Return key outside textareas on a Asp.Net web page (containing ajax code)

    - by Achim
    Hi, I have an Asp.Net web page, having the common Asp.Net form. The outer "border" of the page (i.e. main menu, header, ...) is build using normal Asp.Net code using a master page. The content of that page uses jQuery to display dynamic forms and to send data to the server. If I push the return key on that page, I jump to a (more or less) random page - which is not what the user expects. ;-) There are some text areas and the user must be able to enter line breaks. Otherwise it would be fine to disable the return key completely. Any bullet proof way to do that? I found some solutions on the web, which capture the keypress event and ignore \x13, but that does not really work. It works as long as the page has just loaded, but as soon as I have clicked on some elements, the return key behaves as usuall. Any hint would be really appreciated! Achim

  • Backend raising (INotify)PropertyChanged events to all connected clients?

    - by Jörg Battermann
    One of our 'frontend' developers keeps requesting from us backend developers that the backend notifies all connected clients (it's a client/server environment) of changes to objects. As in: whenever one user makes a change, all other connected clients must be notified immediately of the change. At the moment our architecture does not have a notification system of that kind and we don't have a sort of pub/sub model for explicitly chosen objects (e.g. the one the frontend is currently implementing).. which would make sense in such a usecase imho, but obviously requires extra implementation. However, I thought frontends typically check for locks for concurrently existing user changes on the same object and rather pull for changes / load on demand and in the background rather than the backend pushing all changes to all clients for all objects constantly.. which seems rather excessive to me. However, it's being argumented that e.g. the MS Entity Framework does in fact publish (INotify)PropertyChanged not only for local changes, but for all such changes including other client connections, but I have found no proof or details regarding this. Can anyone shed some light into this? Do other e.g. ORMs etc provide broadcasted (INotify)PropertyChanged events on entities?

  • Add KO "data-bind" attribute on $(document).ready

    - by M.Babcock
    Preface I've rarely ever been a JS developer and this is my first attempt at doing something with Knockout.js. The question to follow likely illustrates both points. Backgound I have a fairly complex MVC3 application that I'm trying to get to work with KO (v2.0.0.0). My MVC app is designed to generically control which fields appear in the view (and how they are added to the view). It makes use of partial views to decide what to draw in the view based on the user's permissions (If the user is in group A then show control A, if the user in group B then show control B or possibly if the user is in group A don't include the control at all). Also, my model is very flat so I'm not sure the built-in ability to apply my ViewModel to a specific portion of the view will help. My solution to this problem is to provide an action in my controller that responds with an object in JSON format with that contains the JQuery selector and the content to assign to the "data-bind" attribute and bind the ViewModel to the View in the $(document).ready event using the values provided. Failed Proof-of-concept My first attempt at proving that this works doesn't actually seem to work, and by "doesn't work" I mean it just doesn't bind the values at all (as can be seen in this jsfiddle). I've tried it with the applyBindings inside of the ready event and not, but it doesn't seem to make any bit of difference. Question What am I doing wrong? Or is this just not something that can work with KO (though I've seen at least one example online doing the same thing and it supposedly works)? Like I said in the preface, I've only ever pretended to be a JS developer (though I've generally gotten it to work in the past) so I'm at a loss where to start trying to figure out what I'm doing wrong. Hopefully this isn't a real noob question.

  • WPF animation/UI features performance and benchmarking

    - by Rich
    I'm working on a relatively small proof-of-concept for some line of business stuff with some fancy WPF UI work. Without even going too crazy, I'm already seeing some really poor performance when using a lot of the features that I thought were the main reason to consider WPF for UI building in the first place. I asked a question on here about why my animation was being stalled the first time it was run, and at the end what I found was that a very simple UserControl was taking almost half a second just to build its visual tree. I was able to get a work around to the symptom, but the fact that it takes that long to initialize a simple control really bothers me. Now, I'm testing my animation with and without the DropShadowEffect, and the result is night and day. A subtle drop shadow makes my control look so much nicer, but it completely ruins the smoothness of the animation. Let me not even start with the font rendering either. The calculation of my animations when the control has a bunch of gradient brushes and a drop shadow make the text blurry for about a full second and then slowly come into focus. So, I guess my question is if there are known studies, blog posts, or articles detailing which features are a hazard in the current version of WPF for business critical applications. Are things like Effects (ie. DropShadowEffect), gradient brushes, key frame animations, etc going to have too much of a negative effect on render quality (or maybe the combinations of these things)? Is the final version of WPF 4.0 going to correct some of these issues? I've read that VS2010 beta has some of these same issues and that they are supposed to be resolved by final release. Is that because of improvements to WPF itself or because half of the application will be rebuilt with the previous technology?

  • Product Catalog Schema design

    - by FlySwat
    I'm building a proof of concept schema for a product catalog to possibly replace a very aging and crufty one we use. In our business, we sell both physical materials and services (one time and reoccurring charges). The current catalog schema has each distinct category broken out into individual tables, while this is nicely normalized and performs well, it is fairly difficult to extend. Adding a new attribute to a particular product involves changing the table schema and backpopulating old data. An idea I've been toying with has been something along the line of a base set of entity tables in 3rd normal form, these will contain the facts that are common among ALL products. Then, I'd like to build an Attribute-Entity-Value schema that allows each entity type to be extended in a flexible way using just data and no schema changes. Finally, I'd like to denormalize this data model into materialized views for each individual entity type. This views are what the application would access. We also have many tables that contain business rules and compatibility rules. These would join against the base entity tables instead of the views. My big concerns here are: Performance - Attribute-Entity-Value schemas are flexible, but typically perform poorly, should I be concerned? More Performance - Denormalizing using materialized views may have some risks, I'm not positive on this yet. Complexity - While this schema is flexible and maintainable using just data, I worry that the complexity of the design might make future schema changes difficult. For those who have designed product catalogs for large scale enterprises, am I going down the totally wrong path? Is there any good best practice schema design reading available for product catalogs?

  • Persisting complex data between postbacks in ASP.NET MVC

    - by Robert Wagner
    I'm developing an ASP.NET MVC 2 application that connects to some services to do data retrieval and update. The services require that I provide the original entity along with the updated entity when updating data. This is so it can do change tracking and optimistic concurrency. The services cannot be changed. My problem is that I need to somehow store the original entity between postbacks. In WebForms, I would have used ViewState, but from what I have read, that is out for MVC. The original values do not have to be tamper proof as the services treat them as untrusted. The entities would be (max) 1k and it is an intranet app. The options I have come up are: Session - Ruled out - Store the entity in the Session, but I don't like this idea as there are no plans to share session between URL - Ruled out - Data is too big HiddenField - Store the serialized entity in a hidden field, perhaps with encryption/encoding HiddenVersion - The entities have a (SQL) version field on them, which I could put into a hidden field. Then on a save I get "original" entity from the services and compare the versions, doing my own optimistic concurrency. Cookies - Like 3 or 4, but using a cookie instead of a hidden field I'm leaning towards option 4, although 3 would be simpler. Are these valid options or am I going down the wrong track? Is there a better way of doing this?

  • reconstructing a tree from its preorder and postorder lists.

    - by NomeN
    Consider the situation where you have two lists of nodes of which all you know is that one is a representation of a preorder traversal of some tree and the other a representation of a postorder traversal of the same tree. I believe it is possible to reconstruct the tree exactly from these two lists, and I think I have an algorithm to do it, but have not proven it. As this will be a part of a masters project I need to be absolutely certain that it is possible and correct (Mathematically proven). However it will not be the focus of the project, so I was wondering if there is a source out there (i.e. paper or book) I could quote for the proof. (Maybe in TAOCP? anybody know the section possibly?) In short, I need a proven algorithm in a quotable resource that reconstructs a tree from its pre and post order traversals. Note: The tree in question will probably not be binary, or balanced, or anything that would make it too easy. Note2: Using only the preorder or the postorder list would be even better, but I do not think it is possible. Note3: A node can have any amount of children. Note4: I only care about the order of siblings. Left or right does not matter when there is only one child.

  • Instantiate type variable in Haskell

    - by danportin
    EDIT: Solved. I was unware that enabling a language extension in the source file did not enable the language extension in GHCi. The solution was to :set FlexibleContexts in GHCi. I recently discovered that type declarations in classes and instances in Haskell are Horn clauses. So I encoded the arithmetic operations from The Art of Prolog, Chapter 3, into Haskell. For instance: fac(0,s(0)). fac(s(N),F) :- fac(N,X), mult(s(N),X,F). class Fac x y | x -> y instance Fac Z (S Z) instance (Fac n x, Mult (S n) x f) => Fac (S n) f pow(s(X),0,0) :- nat(X). pow(0,s(X),s(0)) :- nat(X). pow(s(N),X,Y) :- pow(N,X,Z), mult(Z,X,Y). class Pow x y z | x y -> z instance (N n) => Pow (S n) Z Z instance (N n) => Pow Z (S n) (S Z) instance (Pow n x z, Mult z x y) => Pow (S n) x y In Prolog, values are insantiated for (logic) variable in a proof. However, I don't understand how to instantiate type variables in Haskell. That is, I don't understand what the Haskell equivalent of a Prolog query ?-f(X1,X2,...,Xn) is. I assume that :t undefined :: (f x1 x2 ... xn) => xi would cause Haskell to instantiate xi, but this gives a Non type-variable argument in the constraint error, even with FlexibleContexts enabled.

  • RDP through TCP Proxy

    - by johng100
    Hi, First time in Stackoverflow and I'm hoping someone can help me. I'm looking at a proof of concept to pass RDP traffic through a TCP Proxy/tunnel which will pass through firewalls using HTTPS. The problem has to do with deploying images to machines and so it can't be assumed that the .NET framework will be present, so C++ is being used at the deployment end of a connection. The basic system I have at present is a program which listens for client connections on a port then passes any data to a WCF service which stores it as a byte array. A deployment machine (using GSoap and C++) polls the WCF service for messages and if it finds them then passes the data onto the target server process via sockets. I know this sounds horrible, but it works for simple test clients and server passing data to and from simple test client and server programs via this WCF/C++/C# proxy layer. But I have to support traffic from RDP, VNC and possibly others, so I need a transparent proxy to do this and am wondering whether the above approach is worth pursuing. I've read up on SSH tunneling and that seems a possibility. My basic question is is it possible to tunnel RDP traffic over HTTPS using custom code. Thanks John

  • What are the most interesting equivalences arising from the Curry-Howard Isomorphism?

    - by Tom
    I came upon the Curry-Howard Isomorphism relatively late in my programming life, and perhaps this contributes to my being utterly fascinated by it. It implies that for every programming concept there exists a precise analogue in formal logic, and vice versa. Here's an "obvious" list of such analogies, off the top of my head: program/definition | proof type/declaration | proposition inhabited type | theorem function | implication function argument | hypothesis/antecedent function result | conclusion/consequent function application | modus ponens recursion | induction identity function | tautology non-terminating function | absurdity tuple | conjunction (and) disjoint union | exclusive disjunction (xor) parametric polymorphism | universal quantification So, to my question: what are some of the more interesting/obscure implications of this isomorphism? I'm no logician so I'm sure I've only scratched the surface with this list. For example, here are some programming notions for which I'm unaware of pithy names in logic: currying | "((a & b) => c) iff (a => (b => c))" scope | "known theory + hypotheses" And here are some logical concepts which I haven't quite pinned down in programming terms: primitive type? | axiom set of valid programs? | theory ? | disjunction (or)
