• web grid server pagination trigger multiple controller call when changing page

  - by Thomas Scattolin

  When I server-filter on "au" my web grid and change page, multiple call to the controller are done : the first with 0 filtering, the second with "a" filtering, the third with "au" filtering. My table load huge data so the first call is longer than others. I see the grid displaying firstly the third call result, then the second, and finally the first call (this order correspond to the response time of my controller due to filter parameter) Why are all that controller call made ? Can't just my controller be called once with my total filter "au" ? What should I do ? Here is my grid : $("#" + gridId).kendoGrid({ selectable: "row", pageable: true, filterable:true, scrollable : true, //scrollable: { // virtual: true //false // Bug : Génère un affichage multiple... //}, navigatable: true, groupable: true, sortable: { mode: "multiple", // enables multi-column sorting allowUnsort: true }, dataSource: { type: "json", serverPaging: true, serverSorting: true, serverFiltering: true, serverGrouping:false, // Ne fonctionne pas... pageSize: '@ViewBag.Pagination', transport: { read: { url: Procvalue + "/LOV", type: "POST", dataType: "json", contentType: "application/json; charset=utf-8" }, parameterMap: function (options, type) { // Mise à jour du format d'envoi des paramètres // pour qu'ils puissent être correctement interprétés côté serveur. // Construction du paramètre sort : if (options.sort != null) { var sort = options.sort; var sort2 = ""; for (i = 0; i < sort.length; i++) { sort2 = sort2 + sort[i].field + '-' + sort[i].dir + '~'; } options.sort = sort2; } if (options.group != null) { var group = options.group; var group2 = ""; for (i = 0; i < group.length; i++) { group2 = group2 + group[i].field + '-' + group[i].dir + '~'; } options.group = group2; } if (options.filter != null) { var filter = options.filter.filters; var filter2 = ""; for (i = 0; i < filter.length; i++) { // Vérification si type colonne == string. // Parcours des colonnes pour trouver celle qui a le même nom de champ. var type = ""; for (j = 0 ; j < colonnes.length ; j++) { if (colonnes[j].champ == filter[i].field) { type = colonnes[j].type; break; } } if (filter2.length == 0) { if (type == "string") { // Avec '' autour de la valeur. filter2 = filter2 + filter[i].field + '~' + filter[i].operator + "~'" + filter[i].value + "'"; } else { // Sans '' autour de la valeur. filter2 = filter2 + filter[i].field + '~' + filter[i].operator + "~" + filter[i].value; } } else { if (type == "string") { // Avec '' autour de la valeur. filter2 = filter2 + '~' + options.filter.logic + '~' + filter[i].field + '~' + filter[i].operator + "~'" + filter[i].value + "'"; }else{ filter2 = filter2 + '~' + options.filter.logic + '~' + filter[i].field + '~' + filter[i].operator + "~" + filter[i].value; } } } options.filter = filter2; } var json = JSON.stringify(options); return json; } }, schema: { data: function (data) { return eval(data.data.Data); }, total: function (data) { return eval(data.data.Total); } }, filter: { logic: "or", filters:filtre(valeur) } }, columns: getColonnes(colonnes) }); Here is my controller : [HttpPost] public ActionResult LOV([DataSourceRequest] DataSourceRequest request) { return Json(CProduitsManager.GetProduits().ToDataSourceResult(request)); }

• Reference methods defined in one JScript file from another JScript

  - by Thomas Svensen

  I am writing some server-side scripts using jscript and WSH. The scripts are getting quite long, and some common functions and variables would fit better in a general library script which I included in my various script instances. But, I cannot find a way reference one JScript file from another. For a moment, I though reading the file contents and passing it to "eval()" could work. But, as it says on MSDN: "Note that new variables or types defined in the eval statement are not visible to the enclosing program." (http://msdn.microsoft.com/en-us/library/b51a45x6.aspx) Is there any way to include/refence a JScript from another one?

• Clear default values using onsubmit

  - by Thomas

  I need to clear the default values from input fields using js, but all of my attempts so far have failed to target and clear the fields. I was hoping to use onSubmit to excute a function to clear all default values (if the user has not changed them) before the form is submitted. <form method='get' class='custom_search widget custom_search_custom_fields__search' onSubmit='clearDefaults' action='http://www.example.com' > <input name='cs-Price-2' id='cs-Price-2' class='short_form' value='Min. Price' /> <input name='cs-Price-3' id='cs-Price-3' class='short_form' value='Max Price' /> <input type='submit' name='search' class='formbutton' value=''/> </form> How would you accomplish this?

• e-interview: SunSpace to WebCenter migration

  - by me

  I had the pleasure to do an e-interview with Ana Neves around the SunSpace to WebCenter migration project.  Below is the english version of the interview.  Enjoy   Peter, you joined Oracle in 2009 through the acquisition of Sun. Becoming a part of Oracle meant many changes. The internal collaboration platform was one of them, as per a post you wrote back in 2011. Sun had SunSpace. How would you describe SunSpace? SunSpace was the internal Community and Social Collaboration platform for the Sun's Global Sales and Services Organization. SunSpace served around 600 communities with a main focus around technology, products and services. SunSpace was a big success. Within 3 months of its launch SunSpace had over 20,000 users and it won the Atlassian "Not just another wiki" Award for the best use of Confluence (https://blogs.oracle.com/peterreiser/entry/goodbye_sunspace_hello_webcenter). What made SunSpace so special? 1. People centric versus  Web centric The main concept of SunSpace put the person in the middle of everything. All relevant information, resources  etc. where dynamically pushed to a person's  myProfile ( Facebook like interface) based on the person's interest and  needs.  2. Ease to use  SunSpace was really easy to use. We spent a lot of time on social interaction design to optimize the user experience.  Also we integrated some sophisticated technology to hide complexity from the user. As example - when a user added a document to SunSpace - we analyzed the content of the document and suggested related metadata and tags to the user based on a sophisticated algorithm which was integrated with the corporate taxonomy. Based on this metadata the document was automatically shared with the relevant communities.  3. Easy to find One of the main use cases for SunSpace was that  a user could quickly find the content and information they needed for their job.  The search implementation was based on:  optimized search engine algorithm using social value based ranking enhancements community facilitated search optimization  faceted search which recommended highly relevant  content like products, communities and experts 4. Social Adoption  - How to build vibrant communities You can deploy the coolest social technology but what if the users are not using it?   To drive user adoption we implemented two  complementary models: 4.1 Community Methodology  We developed a set of best practices on how to create, run and sustain communities including: community structure and types (e.g. Community of Practice, Community of Interest etc.) & tips and tricks on how to build a "vibrant " communities, Community Health check etc.  These best practices where constantly tuned and updated by the community of community drivers. 4.2. Social Value System To drive user adoption there is ONE key  question you  have to answer for each individual user: What's In It For Me (WIIFM) We developed a Social Value System called Community Equity which measures the social value flow between People, Content and Metadata. Based on this technology we added "Gamfication" techniques (although at that time this term did not exist ) to SunSpace to honor people for the active contribution and participation.  As example: All  social credentials a user earned trough active community participation where dynamically displayed on her/his myProfile. How would you describe WebCenter? Oracle WebCenter (@oraclewebcenter) is the Oracle's  user engagement platform for social business. It helps people work together more efficiently through contextual collaboration tools that optimize connections between people, information, and applications and ensures users have access to the right information in the context of the business process in which they are engaged. Oracle WebCenter can help your organization deliver contextual and targeted Web experiences to users and enable employees to access information and applications through intuitive portals, composite applications, and mash-ups. How does it compare to SunSpace in terms of functionality? Before I answer this question, I would like to point out some limitation we started to see with the current SunSpace implementation. Due to the massive growth of the user population (>20,000 users), we experienced  performance and scalability challenges with the current technology. Also at the time - Sun Internal Communications and SunIT planned to replace the entire Sun Intranet with SunSpace. We  kicked-off a project to evaluate the enterprise level technology which eventually would replace the good old static Intranet.  And then Oracle acquired Sun. We already had defined the functional requirements for the Intranet replacement with a Social Enterprise Stack and we just needed to evaluate the functional requirements against WebCenter   Below are the summary of this evaluation  MyProfile SunSpace WebCenter How WebCenter Works Home MyProfile: to access, click on your name at the top of any WebCenter page Your name, title, and reporting line are displayed.  Sub-tabs show your activity stream (Activities); people in your network (Connections); files you have uploaded (Documents); your contact information (Organization); and any personal information you wish to share (About).   Files MyFiles Allows you to upload, download and store documents or wiki pages within folders and subfolders.  The WebDav interface allows you to download / upload files / folders with a simple drag and drop to / from your local machine.  Tagging is supported and recommended. Network HomeMyConnections Home: displays the activity stream of individuals in your network.MyConnections: shows individuals in your network.  Click on a person's name to see their contact info and link to their profile. Status Updates MyProfle > Activties Add and displays  your recent activties and status updates. Watches Preferences > Subscriptions > Current Subscriptions Receive email notifications when  pages / spaces you watch are modified. Drafts N/A WebCenter does not support Drafts Settings Preferences: to access, click on 'Preferences' at the top of any WebCenter page Set your general preferences, as well as your WebCenter messaging, search and mail settings. MyCommunities MySpaces: to access, click on 'Spaces' at the top of any WebCenter page Displays MySpaces (communities you are a member of); and Recent Spaces (communities you have recently visited). Community SunSpace Webcenter How Webcenter Works Home Home Displays a community introduction and activity stream.  Members can add messages, links or documents via the Community Message Board. No Top Contributors widget. People Members Lists members of the community. The Mail All Members feature allows moderators and participants to send a message to all members of the community. Membership Management can be found under > Manage > Members News News Members can post and access latest community news and they can subscribe to news using an RSS reader Documents Documents Allows community members to upload, download and store documents or wiki pages within folders and subfolders.  The WebDav interface allows participants to download / upload files / folders with a simple drag and drop to / from your local machine.  Tagging is supported and recommended. Wiki Wiki Allows community members to create and update web pages with a WYSIWYG editor.  Note: WebCenter does not support macros or portlet embedding. Forum Forum Post community forum topics. Contribute to community forum conversations.  N/A Calendar Update and/or view the Community Calendar. N/A Analytics Displays detailed analytics data (views,downloads, unique users etc.) for Pages, Wiki, Documents, and Forum in a given community space. What is the adoption of WebCenter at Oracle? The entire Intranet serving around 100,000 users  is running on WebCenter Content.  For professional communities we use WebCenter Portal and Spaces. Currently we have around 6,000 community spaces with  around 40,000 members.  Does Oracle have any metrics to assess usage and impact of WebCenter? Can you give us some examples? Sure -  we have a lot of metrics   For the Intranet we use traditional metrics like pageviews, monthly unique visitors and unique visits.  For Communities we use the WebCenter Portal/Spaces analytics service which gives as a wealth of data. The key metrics we track are: Space traffic (PageViews, Unique Users) Wiki,Documents (views, downloads etc.) Forum (users, views, posts etc.) Registered members over time  Depending on the community we can filter/segment the metrics by User Properties e.g. Country, Organization, Job Role etc. What are you doing to improve usage and impact? 1. We  integrating the WebCenter social services/fabric into all  main business applications. As example The Fusion CRM deployment is seamless integrated with Oracle Social Network (OSN) and all conversation around an opportunity or customer engagement is  done in OSN (see youtube video). 2. We drive Social Best Practice trough a program called "Social Networking & Business Collaboration (SNBC) program" You worked both with WebCenter and SunSpace. Knowing what you know today, if you had the chance to choose between the two, which one would you choose? Why? That's a tricky question   In the early days of  the Social Enterprise implementation (we started SunSpace in 2006), we needed an agile and easy to deploy technology to keep up with the users requirements. Sometimes we pushed two releases per day  and we were in a permanent perpetual beta mode - SunSpace was perfect for that.  After the social implementation matured over time - community generated content became business critical and we saw a change in the  requirements from agile to stability, scalability and reliability  of the infrastructure.  WebCenter is the right choice for such an enterprise-level deployment.  You are a WebCenter Evangelist at Oracle. What do you do as part of that role? Our  role is to help position Oracle as one of the key thought leaders and solutions provider for Social Business. In addition we drive social innovation trough our Oracle Appslab  team. Is that a full time role? Yes  How many other Evangelists are there in Oracle? We are currently 5 people in the WebCenter evangelist team (@webcentervoices): Christian Finn (@cfinn) leads the team - Christian came from the Microsoft Sharepoint product management team and is a recognized expert in Social Business and Enterprise Collaboration. Noël Jaffré  (@noeljaffre) is our Web Experience Management (WEM) guru and came to Oracle via FatWire acquisition (now WebCenter Sites). Jake Kuramoto (@theapplab) is part of the Oracle AppsLab innovation  team - Jake is well known as  the driving force behind  http://theappslab.com  a blog around social and innovation.  Noel Portugal (@noelportugal) is a developer in the Oracle AppsLab innovation team - he is the inventor of OraTweet - Oracle's internal tweeting platform  Peter Reiser (@peterreiser) is  a Social Business guru and the inventor of SunSpace and Community Equity.  What area of the business do you and the rest of the Evangelists sit in? What area of the organisation is responsible for WebCenter? We are part of the WebCenter product management  organization.  Is WebCenter part of the Knowledge Management strategy? Oracle WebCenter is the Oracle's user engagement platform for social business. It brings together the most complete portfolio of portal, web experience management, content, social and collaboration technologies into a single product suite and is the product foundation of the Oracle Knowledge Management strategy.  I am aware Oracle also uses Beehive internally. How would you describe Beehive? Oracle Beehive provides an integrated set of communication and collaboration services built on a single scalable, secure, enterprise-class platform Beehive is  internally used for enterprise wide mail, calendar and real collaboration (Web conferencing) services.  Are Beehive and WebCenter connected? Historically Beehive and WebCenter Portal & Content had some overlap in functionally. (Hey - if  a company has an acquisition strategy to strengthen its product offering and accelerate  innovation, it's pretty normal that functional overlap exists  :- )) A key objective of the WebCenter strategy is  to combine all social and collaboration offerings under the WebCenter product family. That means that certain Beehive components  will be integrated into the overall WebCenter product offering.  Are there any other internal collaboration tools at Oracle? Which ones There here are two other main social tools which are widely used at Oracle  Oracle Connect was the first social tool the Oracle AppsLab team created in 2007 - see (Jake's blog post for details). It is still extensively used. ... and as a former Sun guy I like this quote from the blog post:  "Traffic to Connect peaked right after the Sun merger in 2010, when it served several hundred thousand pageviews each month; since then, traffic has subsided, but still averages tens of thousands of pageviews to several thousand users each month." Oratweet - Oracle internal microblogging platform has been used since June 2008 and it is still growing.  It's entirely written in Oracle Application Express (APEX) which is a rapid web application development tool for the Oracle database. Wanna try it out? Here you can download the code.  What is Oracle's strategy regarding (all these) collaboration tools? Pretty straight forward. The strategy is to seamless  integrate the WebCenter social & collaboration services into all Business Applications to help customers to socialize their enterprise.

• Implementation of a general-purpose object structure (property bag)

  - by Thomas Wanner

  We need to implement some general-purpose object structure, much like an object in dynamic languages, that would give us a possibility of creating the whole object graph on-the-fly. This class has to be serializable and somehow user friendly. So far we have made some experiments with class derived from Dictionary<string, object> using the dot notation path to store properties and collections in the object tree. We have also find an article that implements something similar, but it doesn't seem to fit completely into our picture either. Do you know about some good implementations / libraries that deal with a similar problem or do you have any (non-trivial) ideas that could help us with our own implementation ? Also, I probably have to say that we are using .NET 3.5, so we can't take advantage of the new features in .NET 4.0 like dynamic type etc. (as far as I know it's also not possible to use any subset of it in .NET 3.5 solution).

• Send custom headers with UIWebView loadRequest

  - by Thomas Clayson

  I want to be able to send some extra headers with my UIWebView loadRequest method. I have tried: NSMutableURLRequest *req = [NSMutableURLRequest requestWithURL:[NSURL URLWithString:@"http://www.reliply.org/tools/requestheaders.php"]]; [req addValue:@"hello" forHTTPHeaderField:@"aHeader"]; [self.theWebView loadRequest:req]; I have also tried subclassing the UIWebView and intercepting the - (BOOL)webView:(UIWebView *)webView shouldStartLoadWithRequest:(NSURLRequest *)request navigationType:(UIWebViewNavigationType)navigationType method. In that method I had a block of code which looked like this: NSMutableURLRequest *newRequest = [request mutableCopy]; for(NSString *key in [customHeaders allKeys]) { [newRequest setValue:[customHeaders valueForKey:key] forHTTPHeaderField:key]; } [self loadRequest:newRequest]; But for some unknown reason it was causing the web view to not load anything (blank frame) and the error message NSURLErrorCancelled (-999) comes up (all known fixes don't fix it for me). So I am at a loss as to what to do. How can I send a custom header along with a UIWebView request? Many thanks!

• How do I set the UI language in vim?

  I saw this on reddit, and it reminded me of one of my vim gripes: It shows the UI in German. Damn you, vim! I want English, but since my OS is set up in German (the standard at our office), I guess vim is actually trying to be helpfull. What magic incantations must I perform to get vim to switch the UI language? I have tried googling on various occasions, but can't seem to find an answer (No, Google, you're my friend *pat*, *pat*, but I allready know how to change the syntax highlighting, thank you!)...

• Guessing the time zone from an arbitrary "location" string?

  - by Thomas

  I'm trying to run some statistics over the Stack Overflow data dump, and for that I would like to know the time zone for each user. However, all I have to go on is the completely free-form "location" string. I'll stress that I'm only looking for an approximation of the time zone; of course, in general this is an unsolvable problem. However, many people fill out their country, state and/or city, which should give a pretty good indication. It's okay if it fails for other cases. It doesn't have to be reliable, it doesn't have to be accurate, it doesn't have to cover all bases. I don't want to waste too much time on this, so I'm wondering if there is some code out there that can make a reasonable guess. Any language, platform, API or library goes. Any ideas?

• Using a checkbox input on a form to send the form data to different email addresses

  - by Cody Thomas

  I am building a form for a client. Here is the rundown. The form will be used as a request to have a staff member contact the person filling out the form. However, there is a list of staff members that will contact them depending on what the subject matter is. So, I want to create a checkbox input section on the form with each staff person's email address attached to a corresponding checkbox. So, the person filling out the form can check only the staff people necessary for their needs. Finally, when the person clicks "submit", the form will be emailed to only the staff members who were checked in the form. I'm at a loss of how to set this up.

• Makefile for DOS/Windows and Cygwin

  - by Thomas Matthews

  I need to have a makefile work under DOS (Windows) and Cygwin. I having problems with the makefile detecting the OS correctly and setting appropriate variables. The objective is to set variables for the following commands, then invoke the commands in rules using the variables: Delete file: rm in Cygwin, del in DOS. Remove directory: rmdir (different parameters in Cygwin and DOS) Copy file: cp in Cygwin, copy in DOS. Testing for file existance: test in Cygwin, IF EXIST in DOS. Listing contents of a file: cat in Cygwin, type in DOS. Here is my attempt, which always uses the else clause: OS_KIND = $(OSTYPE) #OSTYPE is an environment variable set by Cygwin. ifeq ($(OS_KIND), cygwin) ENV_OS = Cygwin RM = rm -f RMDIR = rmdir -r CP = cp REN = mv IF_EXIST = test -a IF_NOT_EXIST = ! test -a LIST_FILE = cat else ENV_OS = Win_Cmd RM = del -f -Q RMDIR = rmdir /S /Q IF_EXIST = if exist IF_NOT_EXIST = if not exist LIST_FILE = type endif I'm using the forward slash character, '/', as a directory separator. This is a problem with the DOS command, as it is interpreting it as program argument rather than a separator. Anybody know how to resolve this issue? Edit: I am using make with Mingw in both Windows Console (DOS) and Cygwin.

• Handle a More Navigation Controller in an Interface Builder based TabBar Application

  - by Thomas Joulin

  Hi, I'm still not clear on how and when to use interface builder. I have a tabbar-based application, in which I added 6 navigations controllers. Instead of having 6 tabs, I would like 3 plus a "More" tab which allows the user to configure the tabs he wants. Is there any way to do that with IB ? And if not, how can I move from IB to a code-based tabbar (provided I already set up a class TabBarController which handles shouldAutoRotate:) Thanks in advance !

• How to compile a C DLL for 64 bit with Visual Studio 2010?

  - by Daren Thomas

  I have a DLL written in C in source code. This is the code for the General Polygon Clipper (in case you are interested). I'm using it in a C# project via the C# wrapper provided on the homepage. This comes with a precompiled DLL. Since switching to a 64bit Development machine with Visual Studio 2010 and Windows 7 64 bit, the application won't run anymore. This is the error I get: An attempt was made to load a program with an incorrect format. This is because of DLLImporting the 32bit gpc.dll, as I have gathered from stuff found on the web. I assume this will all go away if I recompile the DLL to 64bit, but can't for the love of me figure out how to do so. My C skills are basic, in that I can write a C program with the GNU tools, but have no experience with various compilers / processors / IDEs etc. I believe I could port this to C#. By that I mean I trust myself to actually pull it off. But I'd prefer not to, since it is a lot of work that I'd prefer a compiler to do for me ;)

• What (pure) Python library to use for AES 256 encryption?

  I am looking for a (preferably pure) python library to do AES 256 encription and decryption. This library should support the CBC cipher mode and use PKCS7 padding according to the answer to an earlier question of mine. The library should at least work on Mac OS X (10.4) and Windows XP. Ideally just by dropping it into the source directory of my project. I have seen this by Josh Davis, but am not sure about how good it is and if it does the required CBC cipher mode...

• How do I get source file information with dumpbin /symbols when compiling with VS 2005?

  - by Thomas Dartsch

  I have a tool which uses the output of dumpbin /symbols to do some dependency analysis with our C/C++ libraries. When we compiled the libs with VS 6.0, the dumpbin COFF SYMBOL TABLE contained entries like 000 00000008 DEBUG notype Filename | .file x:\mydir\mysource.c allowing me to get the relationship between sources and defined/used symbols, which is essential for my tool.
