• jQuery DataLink - Does DataLink solve my use case?

  - by AnApprentice

  Hello, I recently heard of the jQuery datalink plugin and wondered if I should be using if for the following: I have a an inbox in my app that consists of the following: Inbox (index) - List of Items (list of mails) Inbox (show) Item Viewer (1 mail) Inbox Unread Counter The challenge I'm having now is a user can mark a mail as read/unread in either view which makes keeping the counter accurate challenging. Can datalink help with this? If so how? Also, I read that datalink requires forms is that true? Or can I bind the links to anything like 0 and anytime a mailitem changes from read to unread it would automatically update? Thanks

  i got a little problem with a wordpress site that uses contact form 7 and android browser (at least android v1.5). when a user submits the cf7 form (using ajax followed by a js redirect) and tries to return to the forms page later (using the back button as well as opening the form's url) the download prompt for a 'downloadfile.bin' appears. this behavior can not be reproduced on any other mobile or desktop browsers. could anyone shed some light on this issue? thank you in advance!

• Using threads and event handlers within a WCF Web Service

  - by user368984

  While making a WCF Web Service, I came across a problem while using a method with a webbrowser control. The method starts a thread and uses a webbrowser control to fill in some forms and click further, waiting for a event handler to fire and return a answer I need. The method is tested and works within its own enviroment, but used in a WCF Web Service enviroment, the event handlers just won't fire. A result of that is the waiting manualresetevent not ending. Is this because of the new thread or because of the bad event handling of the web service? If yes, what is a reasonable solution?

• How does the Amazon Recommendation feature work?

  - by Rachel

  What technology goes in behind the screens of Amazon recommendation technology? I believe that Amazon recommendation is currently the best in the market, but how do they provide us with such relevant recommendations? Recently, we have been involved with similar recommendation kind of project, but would surely like to know about the in and outs of the Amazon recommendation technology from a technical standpoint. Any inputs would be highly appreciated. Update: This patent explains how personalized recommendations are done but it is not very technical, and so it would be really nice if some insights could be provided. From the comments of Dave, Affinity Analysis forms the basis for such kind of Recommendation Engines. Also here are some good reads on the Topic Demystifying Market Basket Analysis Market Basket Analysis Affinity Analysis Suggested Reading: Data Mining: Concepts and Technique

• Exposing some live data on a website - New to ASP.NET, need guidelines

  - by Carlos

  I have a large .NET based system running within the company intranet, which allows winforms users to see some live calculated numbers and a custom winforms control drawn live (but not real-time). The Forms users can also affect the operation of the system. I would like to just show the live numbers on a website, along with the custom control. Nothing needs to come back from the web user, as the web app is meant to be just for monitoring. All the numbers can be calculated at the server. It's been a long time since I touched ASP.NET, and I need to know how to proceed. What are the steps in building and deploying such a website? Any caveats I need to look out for?

• public DialogResult ShowDialog() help!

  - by Luke

  I have two forms. The first form is the mainForm, this never goes anywhere. On opening the second form (saveForm), it will display over the top. When i close this form, I want a certain piece of code in the mainForm to run. I assume this is the correct way to get this to happen? The code on saveForm when I close and return to the mainForm: private void btnSaveDetails_Click(object sender, EventArgs e) { Delivery d = new Delivery(txtNameBox.Text, txtAddressBox.Text, txtDayBox.Text, txtTimeBox.Text, txtMealBox.Text, txtInstructionsBox.Text, txtStatusBox.Text); mainForm.myDeliveries.Add(d); this.Close(); } Any ideas?

• Show file extensions in document libraries in Sharepoint 2010

  - by sebastian

  I've got a Sharepoint site collection with several sub sites each having their own document library. Now I want to add the file extensions to the document names in all those libraries. How should I do this? I've seen tips telling you to modify the onet.xml-file, but they never look like mine do, and furthermore I don't know for sure what happens to that onet.xml-file - does it change the existing libraries? Other tips tell me to use Sharepoint designer, that would mean I'll have to do it for every view in every library, wouldn't it? So I'd prefer doing it from code, where I feel more comfortable and where I can automate the process. So, all I want is to replace the "Name (linked to document with edit menu)" with the "Name (for use in forms)" but still keep the link and the edit menu. I've found I need to use the FileLeafRef-field, but I don't know how! Thankful for any new clues, Sebastian

• Continuous Deployment with an ASP.NET website?

  - by Amber Shah

  I have a website in C#/ASP.NET that is currently in development. When we are in production, I would like to do releases frequently over the course of the day, as we fix bugs and add features (like this: http://toni.org/2010/05/19/in-praise-of-continuous-deployment-the-wordpress-com-story/). If you upload a new version of the site or even change a single file, it kicks out the users that are currently logged in and makes them start over any forms and such. Is there a secret to being able to do deployments without interfering with users for .NET sites?

• Model View Presenter plus ASP.NET Web Service; where does the asmx live?

  - by Dirk

  I've been slowly transitioning from a traditional web forms architecture to the MVP pattern (Passive View). So far, it's been fairly easy to implement b/c the views I've dealt with have all employed a classic PostBack model. However, I've come across my first view that will refresh portions of itself via web services. I can't grok where the web service should live (Presenter I think) or how to expose that asmx end point to my View while still maintaining the clean separation of concerns/testability that MVP affords me. I've searched far and wide for some examples on how this might be implemented and have come up with nothing. Please help!

• MS Word to Stylesheet

  - by Chris Johnson

  Is there an easy way to automatically convert a bunch of MS Word documents to xslt stylesheets that can be displayed in the browser? What I have is a large collection of forms in Word format that have to be displayed in the browser, or sent to the user, with known fields populated from a data source, edited by a user and, finally, printed (including the original headers and footers). The data entered by the user will not need to be saved. I'm not sure if converting the documents to stylesheets is even feasible. Maybe someone has a better idea of how to achieve this? Installing Office on the server is not an option in my case.

• Pros and Cons of Access Data Project (MS Access front end with SQL Server Backend)

  - by webworm

  I have been tasked with moving an existing MS Access application (mdb) over to an Access Data Project (adp). Basically the Access forms will remain the same but the data will be migrated over to SQL Server. I am not too familiar with Access Data Projects so I was hoping I could get some opinions on the pros and cons of using them. My first thought was to convert this to a web application or even a Winform application, however I really wanted to perform due dilligence in looking at Access Data Projects before making a decision. Thanks for any assistance.

• Rails + facebox + authlogic - how?

  - by Vitaly

  Hello, on my web site I want to have login/registration form in modal window done using facebox (jQuery plugin). What is better: Create view with one method and template that has form and refer facebox to this view. Create static HTML file in public directory and refer facebox to this static page. What I want to achieve is: Easy verification (like "user name already taken", "password confirmation doesn't match password" and stuff like that). Easy submit and redirect I'm new to Rails, I just know about forms verification in Django, so for Django I would probably choose option 1, but it might be another thing in Ruby.

I am pretty much confused about all this. Can someone explain a little. Thanks.

• Howto Plot "Reverse" Cumulative Frequency Graph With ECDF

  - by neversaint

  I have no problem plotting the following cumulative frequency graph plot like this. library(Hmisc) pre.test <- rnorm(100,50,10) post.test <- rnorm(100,55,10) x <- c(pre.test, post.test) g <- c(rep('Pre',length(pre.test)),rep('Post',length(post.test))) Ecdf(x, group=g, what="f", xlab='Test Results', label.curves=list(keys=1:2)) But I want to show the graph in forms of the "reverse" cumulative frequency of values x ? (i.e. something equivalent to what="1-f"). Is there a way to do it? Other suggestions in R other than using Hmisc are also very much welcomed.

• Process.WaitForExit not triggering with __debugbreak

  - by Cypher2100

  I'm trying to write a program to test student code against a good implementation. I have a C++ console app that will run one test at a time determined by the command line args and a C# .net forms app that calls the c++ app once for each test. The goal is to be able to detect not just pass/fail for each test, but also "infinite" (5secs) loop and exceptions (their code dying for whatever reason). The problem is that not all errors kill the C++ app. If they corrupt the heap the system calls __debugbreak which pops up a window saying Debug Error! HEAP CORRUPTION DETECTED... My C# app is using Process.WaitForExit(5000) to wait, but this error doesn't count as an exit, so I see a timeout. So my question is, how can I either get the C# app to detect that this is an error OR how can I get the C++ app to die when this error occurs rather than giving a dialog box and asking if I want to debug?

• Why my WCF Service returns xml serialized objects?

  - by user294554

  Hi, I'm new here and I hope anyonte can help me. I have WCF Service and Windows Forms working with this client written in VB.NET. The Service class started to return xml serialized objects, but all my classes on Service side are DataContract-s and the service class is DataContractFormat. I googled everywhere about serializations and I couldn't find reason why it started to do that. I checked my classes and service, app.config file, but I couldn't find anything. I checked Reference.vb class, and it's System.Xml.Serialization.XmlElementAttribute everywhere. The question may seem dummy, but I really don't know what to do. I just want to know what can cause the service to act like that. Thank you.

• what are the recent dataStructure and algorithms that one should know?

  - by Shamik

  Recently I came across the SkipList data structure. It really helped me to solve one otherwise critical problem to be solved. I was struggling to solve the same problem with Balanced Binary tree but it became very complex as the tree needs to be always balanced and I wanted to know the existence of not only a particular value but values in certain range. SkipList helped me to solve that problem effectively. I am wondering what else data structures that I need to know? I know - Array, List, Stack, Queue, Linked List, hashtable, tree and its different forms like B-tree, Trie etc. Would like to know if you find some other data structure/concept very interesting to know yet effective enough to be used in a daily development cycle.

• -1 as a return value

  - by dimadima

  This question is specifically about PHP, but I'm guessing it might be applicable to other languages as well. I've noticed that between PHP4 and PHP5, the designers of the language shifted away from using -1 as a return value to using constants or other forms of output. This makes sense, as -1 is not particularly evocative, and I'm guessing this practice led to confusion. That said, I am sometimes inclined to return -1 when I want to quickly add another return option to a function, and -1 often seems like a perfectly valid way to express the outcome I am coding for. So here are my questions: Is my observation generally correct, regarding the move away from -1 as a return value in PHP5 vs PHP4? What are the cons of returning -1, beyond for the reason I mentioned above, wherein the -1 return value doesn't contribute positively to code clarity?

• How to handle existing indexed Mixed Case url's?

  - by marcusstarnes

  I have an asp.net web forms application that has been live for a number of years and as such has quite a lot of indexed content on google. Ideally, I'd prefer that all Url's for the website are in lowercase but I understand that having 2 versions of the same content indexed in search engines (MixedCase.aspx and mixedcase.aspx) will be bad for seo. I was wondering: a) Should I just leave everything in its current Mixed Case form and never change it? OR b) I can change the code so everything is in lowercase from here on in, BUT, is there a way of doing this so as the search engines are aware of this change and don't penalise me?
