  • Office 2010: It&rsquo;s not just DOC(X) and XLS(X)

    - by andrewbrust
    Office 2010 has released to manufacturing.  The bits have left the (product team’s) building.  Will you upgrade? This version of Office is officially numbered 14, a designation that correlates with the various releases, through the years, of Microsoft Word.  There were six major versions of Word for DOS, during whose release cycles came three 16-bit Windows versions.  Then, starting with Word 95 and counting through Word 2007, there have been six more versions – all for the 32-bit Windows platform.  Skip version 13 to ward off folksy bad luck (and, perhaps, the bugs that could come with it) and that brings us to version 14, which includes implementations for both 32- and 64-bit Windows platforms.  We’ve come a long way baby.  Or have we? As it does every three years or so, debate will now start to rage on over whether we need a “14th” version the PC platform’s standard word processor, or a “13th” version of the spreadsheet.  If you accept the premise of that question, then you may be on a slippery slope toward answering it in the negative.  Thing is, that premise is valid for certain customers and not others. The Microsoft Office product has morphed from one that offered core word processing, spreadsheet, presentation and email functionality to a suite of applications that provides unique, new value-added features, and even whole applications, in the context of those core services.  The core apps thus grow in mission: Excel is a BI tool.  Word is a collaborative editorial system for the production of publications.  PowerPoint is a media production platform for for live presentations and, increasingly, for delivering more effective presentations online.  Outlook is a time and task management system.  Access is a rich client front-end for data-driven self-service SharePoint applications.  OneNote helps you capture ideas, corral random thoughts in a semi-structured way, and then tie them back to other, more rigidly structured, Office documents. Google Docs and other cloud productivity platforms like Zoho don’t really do these things.  And there is a growing chorus of voices who say that they shouldn’t, because those ancillary capabilities are over-engineered, over-produced and “under-necessary.”  They might say Microsoft is layering on superfluous capabilities to avoid admitting that Office’s core capabilities, the ones people really need, have become commoditized. It’s hard to take sides in that argument, because different people, and the different companies that employ them, have different needs.  For my own needs, it all comes down to three basic questions: will the new version of Office save me time, will it make the mundane parts of my job easier, and will it augment my services to customers?  I need my time back.  I need to spend more of it with my family, and more of it focusing on my own core capabilities rather than the administrative tasks around them.  And I also need my customers to be able to get more value out of the services I provide. Help me triage my inbox, help me get proposals done more quickly and make them easier to read.  Let me get my presentations done faster, make them more effective and make it easier for me to reuse materials from other presentations.  And, since I’m in the BI and data business, help me and my customers manage data and analytics more easily, both on the desktop and online. Those are my criteria.  And, with those in mind, Office 2010 is looking like a worthwhile upgrade.  Perhaps it’s not earth-shattering, but it offers a combination of incremental improvements and a few new major capabilities that I think are quite compelling.  I provide a brief roundup of them here.  It’s admittedly arbitrary and not comprehensive, but I think it tells the Office 2010 story effectively. Across the Suite More than any other, this release of Office aims to give collaboration a real workout.  In certain apps, for the first time, documents can be opened simultaneously by multiple users, with colleagues’ changes appearing in near real-time.  Web-browser-based versions of Word, Excel, PowerPoint and OneNote will be available to extend collaboration to contributors who are off the corporate network. The ribbon user interface is now more pervasive (for example, it appears in OneNote and in Outlook’s main window).  It’s also customizable, allowing users to add, easily, buttons and options of their choosing, into new tabs, or into new groups within existing tabs. Microsoft has also taken the File menu (which was the “Office Button” menu in the 2007 release) and made it into a full-screen “Backstage” view where document-wide operations, like saving, printing and online publishing are performed. And because, more and more, heavily formatted content is cut and pasted between documents and applications, Office 2010 makes it easier to manage the retention or jettisoning of that formatting right as the paste operation is performed.  That’s much nicer than stripping it off, or adding it back, afterwards. And, speaking of pasting, a number of Office apps now make it especially easy to insert screenshots within their documents.  I know that’s useful to me, because I often document or critique applications and need to show them in action.  For the vast majority of users, I expect that this feature will be more useful for capturing snapshots of Web pages, but we’ll have to see whether this feature becomes popular.   Excel At first glance, Excel 2010 looks and acts nearly identically to the 2007 version.  But additional glances are necessary.  It’s important to understand that lots of people in the working world use Excel as more of a database, analytics and mathematical modeling tool than merely as a spreadsheet.  And it’s also important to understand that Excel wasn’t designed to handle such workloads past a certain scale.  That all changes with this release. The first reason things change is that Excel has been tuned for performance.  It’s been optimized for multi-threaded operation; previously lengthy processes have been shortened, especially for large data sets; more rows and columns are allowed and, for the first time, Excel (and the rest of Office) is available in a 64-bit version.  For Excel, this means users can take advantage of more than the 2GB of memory that the 32-bit version is limited to. On the analysis side, Excel 2010 adds Sparklines (tiny charts that fit into a single cell and can therefore be presented down an entire column or across a row) and Slicers (a more user-friendly filter mechanism for PivotTables and charts, which visually indicates what the filtered state of a given data member is).  But most important, Excel 2010 supports the new PowerPIvot add-in which brings true self-service BI to Office.  PowerPivot allows users to import data from almost anywhere, model it, and then analyze it.  Rather than forcing users to build “spreadmarts” or use corporate-built data warehouses, PowerPivot models function as true columnar, in-memory OLAP cubes that can accommodate millions of rows of data and deliver fast drill-down performance. And speaking of OLAP, Excel 2010 now supports an important Analysis Services OLAP feature called write-back.  Write-back is especially useful in financial forecasting scenarios for which Excel is the natural home.  Support for write-back is long overdue, but I’m still glad it’s there, because I had almost given up on it.   PowerPoint This version of PowerPoint marks its progression from a presentation tool to a video and photo editing and production tool.  Whether or not it’s successful in this pursuit, and if offering this is even a sensible goal, is another question. Regardless, the new capabilities are kind of interesting.  A greatly enhanced set of slide transitions with 3D effects; in-product photo and video editing; accommodation of embedded videos from services such as YouTube; and the ability to save a presentation as a video each lay testimony to PowerPoint’s transformation into a media tool and away from a pure presentation tool. These capabilities also recognize the importance of the Web as both a source for materials and a channel for disseminating PowerPoint output. Congruent with that is PowerPoint’s new ability to broadcast a slide presentation, using a quickly-generated public URL, without involving the hassle or expense of a Web meeting service like GoToMeeting or Microsoft’s own LiveMeeting.  Slides presented through this broadcast feature retain full color fidelity and transitions and animations are preserved as well.   Outlook Microsoft’s ubiquitous email/calendar/contact/task management tool gains long overdue speed improvements, especially against POP3 email accounts.  Outlook 2010 also supports multiple Exchange accounts, rather than just one; tighter integration with OneNote; and a new Social Connector providing integration with, and presence information from, online social network services like LinkedIn and Facebook (not to mention Windows Live).  A revamped conversation view now includes messages that are part of a given thread regardless of which folder they may be stored in. I don’t know yet how well the Social Connector will work or whether it will keep Outlook relevant to those who live on Facebook and LinkedIn.  But among the other features, there’s very little not to like.   OneNote To me, OneNote is the part of Office that just keeps getting better.  There is one major caveat to this, which I’ll cover in a moment, but let’s first catalog what new stuff OneNote 2010 brings.  The best part of OneNote, is the way each of its versions have managed hierarchy: Notebooks have sections, sections have pages, pages have sub pages, multiple notes can be contained in either, and each note supports infinite levels of indentation.  None of that is new to 2010, but the new version does make creation of pages and subpages easier and also makes simple work out of promoting and demoting pages from sub page to full page status.  And relationships between pages are quite easy to create now: much like a Wiki, simply typing a page’s name in double-square-brackets (“[[…]]”) creates a link to it. OneNote is also great at integrating content outside of its notebooks.  With a new Dock to Desktop feature, OneNote becomes aware of what window is displayed in the rest of the screen and, if it’s an Office document or a Web page, links the notes you’re typing, at the time, to it.  A single click from your notes later on will bring that same document or Web page back on-screen.  Embedding content from Web pages and elsewhere is also easier.  Using OneNote’s Windows Key+S combination to grab part of the screen now allows you to specify the destination of that bitmap instead of automatically creating a new note in the Unfiled Notes area.  Using the Send to OneNote buttons in Internet Explorer and Outlook result in the same choice. Collaboration gets better too.  Real-time multi-author editing is better accommodated and determining author lineage of particular changes is easily carried out. My one pet peeve with OneNote is the difficulty using it when I’m not one a Windows PC.  OneNote’s main competitor, Evernote, while I believe inferior in terms of features, has client versions for PC, Mac, Windows Mobile, Android, iPhone, iPad and Web browsers.  Since I have an Android phone and an iPad, I am practically forced to use it.  However, the OneNote Web app should help here, as should a forthcoming version of OneNote for Windows Phone 7.  In the mean time, it turns out that using OneNote’s Email Page ribbon button lets you move a OneNote page easily into EverNote (since every EverNote account gets a unique email address for adding notes) and that Evernote’s Email function combined with Outlook’s Send to OneNote button (in the Move group of the ribbon’s Home tab) can achieve the reverse.   Access To me, the big change in Access 2007 was its tight integration with SharePoint lists.  Access 2010 and SharePoint 2010 continue this integration with the introduction of SharePoint’s Access Services.  Much as Excel Services provides a SharePoint-hosted experience for viewing (and now editing) Excel spreadsheet, PivotTable and chart content, Access Services allows for SharePoint browser-hosted editing of Access data within the forms that are built in the Access client itself. To me this makes all kinds of sense.  Although it does beg the question of where to draw the line between Access, InfoPath, SharePoint list maintenance and SharePoint 2010’s new Business Connectivity Services.  Each of these tools provide overlapping data entry and data maintenance functionality. But if you do prefer Access, then you’ll like  things like templates and application parts that make it easier to get off the blank page.  These features help you quickly get tables, forms and reports built out.  To make things look nice, Access even gets its own version of Excel’s Conditional Formatting feature, letting you add data bars and data-driven text formatting.   Word As I said at the beginning of this post, upgrades to Office are about much more than enhancing the suite’s flagship word processing application. So are there any enhancements in Word worth mentioning?  I think so.  The most important one has to be the collaboration features.  Essentially, when a user opens a Word document that is in a SharePoint document library (or Windows Live SkyDrive folder), rather than the whole document being locked, Word has the ability to observe more granular locks on the individual paragraphs being edited.  Word also shows you who’s editing what and its Save function morphs into a sync feature that both saves your changes and loads those made by anyone editing the document concurrently. There’s also a new navigation pane that lets you manage sections in your document in much the same way as you manage slides in a PowerPoint deck.  Using the navigation pane, you can reorder sections, insert new ones, or promote and demote sections in the outline hierarchy.  Not earth shattering, but nice.   Other Apps and Summarized Findings What about InfoPath, Publisher, Visio and Project?  I haven’t looked at them yet.  And for this post, I think that’s fine.  While those apps (and, arguably, Access) cater to specific tasks, I think the apps we’ve looked at in this post service the general purpose needs of most users.  And the theme in those 2010 apps is clear: collaboration is key, the Web and productivity are indivisible, and making data and analytics into a self-service amenity is the way to go.  But perhaps most of all, features are still important, as long as they get you through your day faster, rather than adding complexity for its own sake.  I would argue that this is true for just about every product Microsoft makes: users want utility, not complexity.

  • C#/.NET Little Wonders: Interlocked CompareExchange()

    - by James Michael Hare
    Once again, in this series of posts I look at the parts of the .NET Framework that may seem trivial, but can help improve your code by making it easier to write and maintain. The index of all my past little wonders posts can be found here. Two posts ago, I discussed the Interlocked Add(), Increment(), and Decrement() methods (here) for adding and subtracting values in a thread-safe, lightweight manner.  Then, last post I talked about the Interlocked Read() and Exchange() methods (here) for safely and efficiently reading and setting 32 or 64 bit values (or references).  This week, we’ll round out the discussion by talking about the Interlocked CompareExchange() method and how it can be put to use to exchange a value if the current value is what you expected it to be. Dirty reads can lead to bad results Many of the uses of Interlocked that we’ve explored so far have centered around either reading, setting, or adding values.  But what happens if you want to do something more complex such as setting a value based on the previous value in some manner? Perhaps you were creating an application that reads a current balance, applies a deposit, and then saves the new modified balance, where of course you’d want that to happen atomically.  If you read the balance, then go to save the new balance and between that time the previous balance has already changed, you’ll have an issue!  Think about it, if we read the current balance as $400, and we are applying a new deposit of $50.75, but meanwhile someone else deposits $200 and sets the total to $600, but then we write a total of $450.75 we’ve lost $200! Now, certainly for int and long values we can use Interlocked.Add() to handles these cases, and it works well for that.  But what if we want to work with doubles, for example?  Let’s say we wanted to add the numbers from 0 to 99,999 in parallel.  We could do this by spawning several parallel tasks to continuously add to a total: 1: double total = 0; 2:  3: Parallel.For(0, 10000, next => 4: { 5: total += next; 6: }); Were this run on one thread using a standard for loop, we’d expect an answer of 4,999,950,000 (the sum of all numbers from 0 to 99,999).  But when we run this in parallel as written above, we’ll likely get something far off.  The result of one of my runs, for example, was 1,281,880,740.  That is way off!  If this were banking software we’d be in big trouble with our clients.  So what happened?  The += operator is not atomic, it will read in the current value, add the result, then store it back into the total.  At any point in all of this another thread could read a “dirty” current total and accidentally “skip” our add.   So, to clean this up, we could use a lock to guarantee concurrency: 1: double total = 0.0; 2: object locker = new object(); 3:  4: Parallel.For(0, count, next => 5: { 6: lock (locker) 7: { 8: total += next; 9: } 10: }); Which will give us the correct result of 4,999,950,000.  One thing to note is that locking can be heavy, especially if the operation being locked over is trivial, or the life of the lock is a high percentage of the work being performed concurrently.  In the case above, the lock consumes pretty much all of the time of each parallel task – and the task being locked on is relatively trivial. Now, let me put in a disclaimer here before we go further: For most uses, lock is more than sufficient for your needs, and is often the simplest solution!    So, if lock is sufficient for most needs, why would we ever consider another solution?  The problem with locking is that it can suspend execution of your thread while it waits for the signal that the lock is free.  Moreover, if the operation being locked over is trivial, the lock can add a very high level of overhead.  This is why things like Interlocked.Increment() perform so well, instead of locking just to perform an increment, we perform the increment with an atomic, lockless method. As with all things performance related, it’s important to profile before jumping to the conclusion that you should optimize everything in your path.  If your profiling shows that locking is causing a high level of waiting in your application, then it’s time to consider lighter alternatives such as Interlocked. CompareExchange() – Exchange existing value if equal some value So let’s look at how we could use CompareExchange() to solve our problem above.  The general syntax of CompareExchange() is: T CompareExchange<T>(ref T location, T newValue, T expectedValue) If the value in location == expectedValue, then newValue is exchanged.  Either way, the value in location (before exchange) is returned. Actually, CompareExchange() is not one method, but a family of overloaded methods that can take int, long, float, double, pointers, or references.  It cannot take other value types (that is, can’t CompareExchange() two DateTime instances directly).  Also keep in mind that the version that takes any reference type (the generic overload) only checks for reference equality, it does not call any overridden Equals(). So how does this help us?  Well, we can grab the current total, and exchange the new value if total hasn’t changed.  This would look like this: 1: // grab the snapshot 2: double current = total; 3:  4: // if the total hasn’t changed since I grabbed the snapshot, then 5: // set it to the new total 6: Interlocked.CompareExchange(ref total, current + next, current); So what the code above says is: if the amount in total (1st arg) is the same as the amount in current (3rd arg), then set total to current + next (2nd arg).  This check and exchange pair is atomic (and thus thread-safe). This works if total is the same as our snapshot in current, but the problem, is what happens if they aren’t the same?  Well, we know that in either case we will get the previous value of total (before the exchange), back as a result.  Thus, we can test this against our snapshot to see if it was the value we expected: 1: // if the value returned is != current, then our snapshot must be out of date 2: // which means we didn't (and shouldn't) apply current + next 3: if (Interlocked.CompareExchange(ref total, current + next, current) != current) 4: { 5: // ooops, total was not equal to our snapshot in current, what should we do??? 6: } So what do we do if we fail?  That’s up to you and the problem you are trying to solve.  It’s possible you would decide to abort the whole transaction, or perhaps do a lightweight spin and try again.  Let’s try that: 1: double current = total; 2:  3: // make first attempt... 4: if (Interlocked.CompareExchange(ref total, current + i, current) != current) 5: { 6: // if we fail, go into a spin wait, spin, and try again until succeed 7: var spinner = new SpinWait(); 8:  9: do 10: { 11: spinner.SpinOnce(); 12: current = total; 13: } 14: while (Interlocked.CompareExchange(ref total, current + i, current) != current); 15: } 16:  This is not trivial code, but it illustrates a possible use of CompareExchange().  What we are doing is first checking to see if we succeed on the first try, and if so great!  If not, we create a SpinWait and then repeat the process of SpinOnce(), grab a fresh snapshot, and repeat until CompareExchnage() succeeds.  You may wonder why not a simple do-while here, and the reason it’s more efficient to only create the SpinWait until we absolutely know we need one, for optimal efficiency. Though not as simple (or maintainable) as a simple lock, this will perform better in many situations.  Comparing an unlocked (and wrong) version, a version using lock, and the Interlocked of the code, we get the following average times for multiple iterations of adding the sum of 100,000 numbers: 1: Unlocked money average time: 2.1 ms 2: Locked money average time: 5.1 ms 3: Interlocked money average time: 3 ms So the Interlocked.CompareExchange(), while heavier to code, came in lighter than the lock, offering a good compromise of safety and performance when we need to reduce contention. CompareExchange() - it’s not just for adding stuff… So that was one simple use of CompareExchange() in the context of adding double values -- which meant we couldn’t have used the simpler Interlocked.Add() -- but it has other uses as well. If you think about it, this really works anytime you want to create something new based on a current value without using a full lock.  For example, you could use it to create a simple lazy instantiation implementation.  In this case, we want to set the lazy instance only if the previous value was null: 1: public static class Lazy<T> where T : class, new() 2: { 3: private static T _instance; 4:  5: public static T Instance 6: { 7: get 8: { 9: // if current is null, we need to create new instance 10: if (_instance == null) 11: { 12: // attempt create, it will only set if previous was null 13: Interlocked.CompareExchange(ref _instance, new T(), (T)null); 14: } 15:  16: return _instance; 17: } 18: } 19: } So, if _instance == null, this will create a new T() and attempt to exchange it with _instance.  If _instance is not null, then it does nothing and we discard the new T() we created. This is a way to create lazy instances of a type where we are more concerned about locking overhead than creating an accidental duplicate which is not used.  In fact, the BCL implementation of Lazy<T> offers a similar thread-safety choice for Publication thread safety, where it will not guarantee only one instance was created, but it will guarantee that all readers get the same instance.  Another possible use would be in concurrent collections.  Let’s say, for example, that you are creating your own brand new super stack that uses a linked list paradigm and is “lock free”.  We could use Interlocked.CompareExchange() to be able to do a lockless Push() which could be more efficient in multi-threaded applications where several threads are pushing and popping on the stack concurrently. Yes, there are already concurrent collections in the BCL (in .NET 4.0 as part of the TPL), but it’s a fun exercise!  So let’s assume we have a node like this: 1: public sealed class Node<T> 2: { 3: // the data for this node 4: public T Data { get; set; } 5:  6: // the link to the next instance 7: internal Node<T> Next { get; set; } 8: } Then, perhaps, our stack’s Push() operation might look something like: 1: public sealed class SuperStack<T> 2: { 3: private volatile T _head; 4:  5: public void Push(T value) 6: { 7: var newNode = new Node<int> { Data = value, Next = _head }; 8:  9: if (Interlocked.CompareExchange(ref _head, newNode, newNode.Next) != newNode.Next) 10: { 11: var spinner = new SpinWait(); 12:  13: do 14: { 15: spinner.SpinOnce(); 16: newNode.Next = _head; 17: } 18: while (Interlocked.CompareExchange(ref _head, newNode, newNode.Next) != newNode.Next); 19: } 20: } 21:  22: // ... 23: } Notice a similar paradigm here as with adding our doubles before.  What we are doing is creating the new Node with the data to push, and with a Next value being the original node referenced by _head.  This will create our stack behavior (LIFO – Last In, First Out).  Now, we have to set _head to now refer to the newNode, but we must first make sure it hasn’t changed! So we check to see if _head has the same value we saved in our snapshot as newNode.Next, and if so, we set _head to newNode.  This is all done atomically, and the result is _head’s original value, as long as the original value was what we assumed it was with newNode.Next, then we are good and we set it without a lock!  If not, we SpinWait and try again. Once again, this is much lighter than locking in highly parallelized code with lots of contention.  If I compare the method above with a similar class using lock, I get the following results for pushing 100,000 items: 1: Locked SuperStack average time: 6 ms 2: Interlocked SuperStack average time: 4.5 ms So, once again, we can get more efficient than a lock, though there is the cost of added code complexity.  Fortunately for you, most of the concurrent collection you’d ever need are already created for you in the System.Collections.Concurrent (here) namespace – for more information, see my Little Wonders – The Concurent Collections Part 1 (here), Part 2 (here), and Part 3 (here). Summary We’ve seen before how the Interlocked class can be used to safely and efficiently add, increment, decrement, read, and exchange values in a multi-threaded environment.  In addition to these, Interlocked CompareExchange() can be used to perform more complex logic without the need of a lock when lock contention is a concern. The added efficiency, though, comes at the cost of more complex code.  As such, the standard lock is often sufficient for most thread-safety needs.  But if profiling indicates you spend a lot of time waiting for locks, or if you just need a lock for something simple such as an increment, decrement, read, exchange, etc., then consider using the Interlocked class’s methods to reduce wait.

  • Hibernate + PostgreSQL : relation does not exist - SQL Error: 0, SQLState: 42P01

Could it be some permission issue? Thanks!

  • Using IIS Application Request Routing (ARR) for ASP.NET MVC

    - by Malcolm Frexner
    I use a simple ASP.NET MVC web (the template you use when you create a new site) and the web works as expected in my live environment. I now try to use IIS Application Request Routing version 2. I have a rule that send all reuqests to a different server that match a rule. The settings are a bit like this: http://blogs.iis.net/wonyoo/archive/2008/07/09/application-request-routing-arr-as-a-reverse-proxy.aspx My rule is just a bit different it is /shop(.*). Only requests that contain shop are send to a different server. I have to use rewrite, not redirect (The same as in the Picture) This works as long as the web the original requests go to is no ASP.NET MVC web. I tried to use a plain htm file in the webfolder and it worked. If put a compiled ASP.NET application into the webfolder it worked. But as soon as I put an ASP.NET MVC web into the folder, request arr served by this application. My understanding is that the ARR should kick in before the web application gets the chance to handle the request. Did anybody use ARR sucessfully as a reverse proxy for a ASP.NET MVC web? EDIT Here is the resulting web config when the rewrite roule is entered. With this rule I get a 404 that indicates that the rule is not used. <?xml version="1.0" encoding="UTF-8"?> <configuration> <configSections> <sectionGroup name="system.web.extensions" type="System.Web.Configuration.SystemWebExtensionsSectionGroup, System.Web.Extensions, Version=3.5.0.0, Culture=neutral, PublicKeyToken=31BF3856AD364E35"> <sectionGroup name="scripting" type="System.Web.Configuration.ScriptingSectionGroup, System.Web.Extensions, Version=3.5.0.0, Culture=neutral, PublicKeyToken=31BF3856AD364E35"> <section name="scriptResourceHandler" type="System.Web.Configuration.ScriptingScriptResourceHandlerSection, System.Web.Extensions, Version=3.5.0.0, Culture=neutral, PublicKeyToken=31BF3856AD364E35" requirePermission="false" allowDefinition="MachineToApplication" /> <sectionGroup name="webServices" type="System.Web.Configuration.ScriptingWebServicesSectionGroup, System.Web.Extensions, Version=3.5.0.0, Culture=neutral, PublicKeyToken=31BF3856AD364E35"> <section name="jsonSerialization" type="System.Web.Configuration.ScriptingJsonSerializationSection, System.Web.Extensions, Version=3.5.0.0, Culture=neutral, PublicKeyToken=31BF3856AD364E35" requirePermission="false" allowDefinition="Everywhere" /> <section name="profileService" type="System.Web.Configuration.ScriptingProfileServiceSection, System.Web.Extensions, Version=3.5.0.0, Culture=neutral, PublicKeyToken=31BF3856AD364E35" requirePermission="false" allowDefinition="MachineToApplication" /> <section name="authenticationService" type="System.Web.Configuration.ScriptingAuthenticationServiceSection, System.Web.Extensions, Version=3.5.0.0, Culture=neutral, PublicKeyToken=31BF3856AD364E35" requirePermission="false" allowDefinition="MachineToApplication" /> <section name="roleService" type="System.Web.Configuration.ScriptingRoleServiceSection, System.Web.Extensions, Version=3.5.0.0, Culture=neutral, PublicKeyToken=31BF3856AD364E35" requirePermission="false" allowDefinition="MachineToApplication" /> </sectionGroup> </sectionGroup> </sectionGroup> </configSections> <appSettings /> <connectionStrings> <add name="ApplicationServices" connectionString="data source=.\SQLEXPRESS;Integrated Security=SSPI;AttachDBFilename=|DataDirectory|aspnetdb.mdf;User Instance=true" providerName="System.Data.SqlClient" /> </connectionStrings> <system.web> <!-- Set compilation debug="true" to insert debugging symbols into the compiled page.

  • autocomplete dropdown in Infragistics ultrawebgrid cell

    - by Rama
    Hi, I want to an autocomplete dropdown control in the ultrawebgrid cell in edit mode, so user can type the data and value is filled in automatically if exists, invalid data should not be permitted. is this possible? I don't want to use webcombo, it is too heavy and I don't need a multi-column dropdown. I want a simple dropdownlist, but the ability for the user to type just like Google suggest, but all the values cached on the client, no roundtrip to server on each key stroke. the control should be like the following one http://www.asp.net/AJAX/AjaxControlToolkit/Samples/ComboBox/ComboBox.aspx thanks, RK

  • Locking Cache Key without Locking the entire Cache

    - by Gandalf
    I have servlets that caches user information rather then retrieving it from the user store on every request (shared Ehcache). The issue I have is that if a client is multi-threaded and they make more then one simultaneous request, before they have been authenticated, then I get this in my log: Retrieving User [Bob] Retrieving User [Bob] Retrieving User [Bob] Returned [Bob] ...caching Returned [Bob] ...caching Returned [Bob] ...caching What I would want is that the first request would call the user service, while the other two requests get blocked - and when the first request returns, and then caches the object, the other two requests go through: Retrieving User [Bob] blocking... blocking... Returned [Bob] ...caching [Bob] found in cache [Bob] found in cache I've thought about locking on the String "Bob" (because due to interning it's always the same object right?). Would that work? And if so how do I keep track of the keys that actually exist in the cache and build a locking mechanism around them that would then return the valid object once it's retrieved. Thanks.

  • Redirect logging output using custom logging handler

    - by mridang
    Hi Guys, I'm using a module in my python app that writes a lot a of messages using the logging module. Initially I was using this in a console application and it was pretty easy to get the logging output to display on the console using a console handler. Now I've developed a GUI version of my app using wxPython and I'd like to display all the logging output to a custom control — a multi-line textCtrl. Is there a way i could create a custom logging handler so i can redirect all the logging output there and display the logging messages wherever/however I want — in this case, a wxPython app. Thanks

  • Google Maps JS API v3 - Simple Multiple Marker Example

    - by Wes
    Fairly new to the Google Maps Api. I've got an array of data that I want to cycle through and plot on a map. Seems fairly simple, but all the multi-marker tutorials I have found are quite complex. Lets use the data array from google's site for an example: var locations = [ ['Bondi Beach', -33.890542, 151.274856, 4], ['Coogee Beach', -33.923036, 151.259052, 5], ['Cronulla Beach', -34.028249, 151.157507, 3], ['Manly Beach', -33.80010128657071, 151.28747820854187, 2], ['Maroubra Beach', -33.950198, 151.259302, 1] ]; I simply want to plot all of these points and have an infoWindow pop up when clicked to display the name. Any help is greatly appreciated!

  • Ajax, Lizard Brain Web Design, JSF, Struts, JavaScript, Mobile Web, Flash, jQuery, GWT, Harmony at I

    - by Kim Won
    Great Indian Developer Summit 2010 – India's Biggest Polyglot Conference and Workshops for IT Software Professionals Bangalore, April 9, 2010: The GIDS.Web Conference and Workshops has announced the complete program of over 30 sessions on how browser and rich web technologies such as AJAX, DHTML, Mashups, Web 2.0, Enterprise 2.0 technologies, and Rich UI technologies are making money and gaining market-share for some of the leading businesses in the world. The GIDS.Web track at Great Indian Developer Summit takes place 21 and 23 April 2010, at the Indian Institute of Science in Bangalore. As one of the longest running independent developer conferences in India, GIDS.Web at the Great Indian Developer Summit 2010 is uniquely positioned to provide a blend of practical, pragmatic and immediately applicable knowledge and a glimpse of the future of technology. During 21 and 23 April 2010, GIDS.Web offers a multi-track conference, workshops, expo show floor, and networking opportunities. The first keynote at GIDS.Web is led by the leading Java EE and Ajax developer, speaker, and author Marty Hall. The best of India's Java and RIA programmers have learnt the subject from Marty's seminal books Core Servlets and JavaServer Pages (first and second editions), More Servlets and JavaServer Pages, and Core Web Programming (first and second editions) from Prentice Hall and Sun Microsystems Press. Marty's keynote address is a comparison of approaches to building rich Internet applications with Ajax. Marty says Ajax development is difficult, and there are several fundamentally different strategies to building Ajaxified Web applications. The keynote address will survey the three most important of these approaches: using an Ajax-enabled JavaScript library such as jQuery, Prototype, Scriptaculous, Dojo, or Ext/JS; using a Web framework such as JSF 2.0 or Struts 2 that has integrated Ajax support; using the Google Web Toolkit (GWT) to build "pure Java" Ajax applications. The talk will compare and contrast these three approaches, discussing the types of applications that fit best for each option. Over the course of the summit Marty will conduct several more sessions on "Choosing an Ajax/JavaScript Toolkit: A Comparison of the Most Popular JavaScript Libraries", "Pure Java Ajax: An Overview of GWT 2.0", "Integrated Ajax Support in JSF 2.0" and "Ajax Support in the Prototype JavaScript Library". The second keynote by the head of Adobe's Flash initiative in India, Ramesh Srinivasaraghavan, explores the state of art in web application development and identify trends that could transform the way we create and use web applications. The talk explains how the Adobe Flash Platform has fuelled this revolution with an integrated set of technologies for delivering the most compelling applications, content and video to the widest possible audience. The Director of Forum Nokia will explain how cloud computing coupled with mobile applications enable consumers to have access to powerful services and improved user experiences never before thought possible.

  • FB.ui and setting popup size

    - by manuelpedrera
    I am using FB.ui with the display parameter set to popup. When the method is 'stream.publish', it autoresizes when the content is loaded. However, when using 'fbml.dialog' (in order to display a multi-friend selector) it shows a size that I'm not able to change (and the content is displayed cropped). I have tried with the following approaches, with no luck: FB.ui({ method: 'fbml.dialog', size: {width: 800, height: 500}, ... FB.ui({ method: 'fbml.dialog', width: 800, height: 500, ... Also I've been looking at the API source code, and it declares the method this way: Method declaration: 'fbml.dialog': { size : { width: 575, height: 300 }, url : 'render_fbml.php', loggedOutIframe : true }... Functions that executes the methods: // the basic call data var call = { cb : cb, id : id, size : method.size || {}, url : FB._domain.www + method.url, params : params }; Any help would be much appreciated...

  • On MacOSX, in a C++ program, what guarantees can I have on file IO

    - by anon
    I am on MacOSX. I am writing a multi threaded program. One thread does logging. The non-logging threads may crash at any time. What conventions should I adopt in the logger / what guarantees can I have? I would prefer a solution where even if I crash during part of a write, previous writes still go to disk, and when reading back the log, I can figure out "ah, I wrote 100 complete enties, then I crashed on the 101th". Thanks!

  • Enhance Localization performances? (ComponentResourceManager.ApplyResources)

    - by Srodriguez
    Dear all, After experiencing some performances issues on my client side, we decided to give a try to some of the performance profilers to try to find the bottleneck or identify the guilty parts of the code. Of course, as many performance investigations, the problems comes from various things, but something I find out is that the ComponentResourceManager.ApplyResources of my user controls takes way too much time in the construction of my forms: more than 24% of the construction time is spent in the ApplyResources inside the InitializeComponent(). This seems rather a lot for only "finding a resource string and putting it in it's container". What is exactly done in the ComponentResourceManager.ApplyResources ? I guess more than searching the string, if not it wouldn't take that long. Is there a way to enhance the performances of the localization? Our software is localized in several languages, so we do need to keep this multi-lingual feature. Any recommendations regarding this issue? Thanks! PS: We are coding in C#, .NET 3.5 SP1.

  • Dynamic Flex verticalaxisrenderers

    - by user276424
    Hi, I've created a linechart in flex using pure as3. I need now to convert it to a dynamic multi axis chart. What I mean by dynamic, is that I can programmatically add or remove axisrenderers from the verticalaxisrenderer array at runtime. It seems i can remove axisrenderers at runtime by simply doing this: verticalAxisRenderers = verticalAxisRenderers.splice(index,1); However, ADDING axisrenderers is not working. I am doing it by so: verticalAxisRenderers.push(ar2); verticalAxisRenderers = verticalAxisRenderers; Where am I going wrong? Please help! Thanks, Tone

  • Blackberry Development, communicating two Blackberry device in a multiplayer game programatically

    - by Nikesh Yadav
    Hi Forum, We are developing a game application for Blackberry, which will have multi player option to let two or more player compete against each other. We have implemented the logic for that and already two or more player are able to play the game simultaneously on single device. Now we want to upgrade our application so that two or more user can compete each other playing from different device and different locations. Can anyone please help me by providing me the way (or code) to achieve this (communicating two blackberry devices over the air to access single session programmaticaly)? I found the code to connect two device using Bluetooth but as the player may situated in different geographic regions we need to achieve this using over the air connection. Thanks in advance. Thanks, Nikesh

  • NInject and thread-safety

    - by cbp
    I am having problems with the following class in a multi-threaded environment: public class Foo { [Inject] public IBar InjectedBar { get; set; } public bool NonInjectedProp { get; set; } public void DoSomething() { /* The following line is causing a null-reference exception */ InjectedBar.DoSomething(); } public Foo(bool nonInjectedProp) { /* This line should inject the InjectedBar property */ KernelContainer.Inject(this); NonInjectedProp = nonInjectedProp; } } This is a legacy class which is why I am using property rather than constructor injection. Sometime when the DoSomething() is called the InjectedBar property is null. In a single-threaded application, everything runs fine. How can this be occuring and how can I prevent it?

  • Draw underlined / strikethrough text ( MULTILINE STRING ) ?

    - by Madhup
    Hi, I have to draw underlined-multiline text with all types of text alignment. I have searched on forums and got some results like: http://davidjhinson.wordpress.com/2009/11/26/underline-text-on-the-iphone/ http://forums.macrumors.com/showthread.php?t=561572 But all draw text for single line only. while i have multi-line text. The situation even become worse when the text alignment is centered. I searched and found that in iphone-sdk-3.2 there are some core-text attributes for underlining a text but no idea how to use that. Besides if I use these my problem would not be solved fully. As I have to draw strikethrough text also. Anybody having idea about this please help.

  • uploadify and absolute filepaths ?

    - by Haroldo
    can anyone with experience of the plugin see anything I'm doing wrong? var SITE_ROOT = 'http://localhost/hf_latest_desktop/'; $("#uploadify").uploadify({ 'uploader' : SITE_ROOT+'st_wd_assets/js/uploadify/scripts/uploadify.swf', 'script' : SITE_ROOT+'st_wd_assets/js/uploadify/scripts/uploadify.php', 'cancelImg' : SITE_ROOT+'st_wd_assets/js/uploadify/cancel.png', 'folder' : SITE_ROOT+'res/img/temp', 'auto' : true, 'multi' : false, 'buttonImg' : SITE_ROOT+'st_wd_assets/img/uploadify-button.png' }); it loads in the swf fine (can see it in firebug), however the upload button does not show and there is no functionality? edit: it looks like it could be something to do with it encoding the " : " entity in the absolute paths for example examining the .swf it the attributed are encoded ie: &buttonImg=http%3A//localhost/hf_latest_desktop/st_wd_assets/img/uploadify-button.png

  • Weblogic is slow to start (11mins) under VM (VirtualBox and VMware)

    - by Vladimir Dyuzhev
    (SOLVED! BY FAKING SYSTEM RANDOM GENERATOR, SEE BELOW) I'm setting up a VM image for my dev/build team. Inside that VM a Weblogic domain should be running. I use Ububtu server distro, WLS 9.2MP3 + ALSB. Everything works OK, quite fast, but at the start time the WLS stops twice for a measurable amounts of time. Two stops in total amount to about 10 minutes delay. For tasks where deployment requires server restart it's very annoying. :-( Sleeping time is not constant, sometimes the server starts very fast, sometimes so-so, sometimes 10 minutes or more. Interesting that if I press Enter while looking at the stopped server, it wakes up much faster, sometimes after a few seconds. WLST (Weblogic Jython shell) is also hanging for quite a time when executed in VM. It doesn't react to Enter though. Here must be some developers who run WLS with a VM. I wonder if others have the same problem? Was someone able to solve it? Here's the server output (just for a case): Java(TM) 2 Runtime Environment, Standard Edition (build 1.5.0_12-b04) Java HotSpot(TM) Client VM (build 1.5.0_12-b04, mixed mode) Starting WLS with line: /shared2/beahome/jdk150_12/bin/java -client -Xmx256m -XX:MaxPermSize=128m -Xverify:none -da -Dplatform.home=/shared2/beahome/weblogic92 -Dwls.home=/shared2/beahome/weblogic92/server -Dwli.home=/shared2/beahome/weblogic92/integration -Dweblogic.management.discover=true -Dwl w.iterativeDev= -Dwlw.testConsole= -Dwlw.logErrorsToConsole= -Dweblogic.ext.dirs=/shared2/beahome/patch_weblogic923/profiles/default/sysext_ manifest_classpath -Dweblogic.management.username=admin -Dweblogic.management.password=wlsadmin -Dweblogic.Name=LOGMGR-admin -Djava.security .policy=/shared2/beahome/weblogic92/server/lib/weblogic.policy weblogic.Server <1-Apr-2010 12:47:22 o'clock PM GMT-05:00> <Notice> <WebLogicServer> <BEA-000395> <Following extensions directory contents added to the end of the classpath: /shared2/beahome/weblogic92/platform/lib/p13n/p13n-schemas.jar:/shared2/beahome/weblogic92/platform/lib/p13n/p13n_common.jar:/shared2/beahom e/weblogic92/platform/lib/p13n/p13n_system.jar:/shared2/beahome/weblogic92/platform/lib/wlp/netuix_common.jar:/shared2/beahome/weblogic92/pl atform/lib/wlp/netuix_schemas.jar:/shared2/beahome/weblogic92/platform/lib/wlp/netuix_system.jar:/shared2/beahome/weblogic92/platform/lib/wl p/wsrp-common.jar> <1-Apr-2010 12:47:22 o'clock PM GMT-05:00> <Info> <WebLogicServer> <BEA-000377> <Starting WebLogic Server with Java HotSpot(TM) Client VM Ve rsion 1.5.0_12-b04 from Sun Microsystems Inc.> <1-Apr-2010 12:47:23 o'clock PM GMT-05:00> <Info> <Management> <BEA-141107> <Version: WebLogic Server 9.2 MP3 Mon Mar 10 08:28:41 EDT 2008 1096261 > <1-Apr-2010 12:47:25 o'clock PM GMT-05:00> <Info> <WebLogicServer> <BEA-000215> <Loaded License : /shared2/beahome/license.bea> <1-Apr-2010 12:47:25 o'clock PM GMT-05:00> <Notice> <WebLogicServer> <BEA-000365> <Server state changed to STARTING> <1-Apr-2010 12:47:25 o'clock PM GMT-05:00> <Info> <WorkManager> <BEA-002900> <Initializing self-tuning thread pool> <1-Apr-2010 12:47:25 o'clock PM GMT-05:00> <Notice> <Log Management> <BEA-170019> <The server log file /shared2/wldomains/beaadmd/LOGMGR/ser vers/LOGMGR-admin/logs/LOGMGR-admin.log is opened.

SecureRandom by default uses /dev/urandom file. For some reason, reading this file under VM comes to halt quite often. Generating console events helps to create more randomness, and release the WLS. For the test purposes I have changed jre/lib/security/java.security file, property to securerandom.source=file:/tmp/big.random.file. Weblogic now starts in 15 seconds.

  • Jquery Validate Issue

    - by Thomas
    I'm using the Jquery validate plugin to validate a multi-step form like this one: http://jquery.bassistance.de/validate/demo/multipart/ Unfortunately, I can't seem to get it to work at all and there is a total lack of documentation to guide me through implemnetation. I think the accordian part of script is firing correctly because the bottom half of the form is being hidden and a 'next' button has been successfuly inserted. However, the form never validates or delivers an error message and it is impossible to move on to the next step. Check it out here: http://www.loftist.com/?page_id=78

This is often important when creating multi-tabbed * forms. */ deferredRender: false, defaults:{bodyStyle:'padding:10px'}, items:[{ title:'Address', layout:'form', defaults: {width: 230}, defaultType: 'textfield', items: [{ fieldLabel: 'Line1', name: 'line1', allowBlank:false, },{ fieldLabel: 'Line2', name: 'line2', },{ fieldLabel: 'City', name: 'city', allowBlank: false, },{ xtype:"combo", fieldLabel:"State", name:"state", hiddenName:"combovalue" }, { fieldLabel: 'Zipcode', name: 'zipcode', allowBlank: false, }] },{ title:'Phone Numbers', layout:'form', defaults: {width: 230}, defaultType: 'textfield', items: [{ fieldLabel: 'Home', name: 'home_phone', },{ fieldLabel: 'Cell', name: 'cell_phone' },{ fieldLabel: 'Emergency', name: 'emergency_phone' }] },{ cls:'x-plain', title:'Notes', layout:'fit', items: { xtype:'htmleditor', name:'notes', fieldLabel:'Notes' } }] }], buttons: [{ text: 'Save' },{ text: 'Cancel' }] }) How do I access the form fields by the name to set their value manually? Thanks

  • Is there a way to mark up code to tell ReSharper not to format it?

    - by adrianbanks
    I quite often use the ReSharper "Clean Up Code" command to format my code to our coding style before checking it into source control. This works well in general, but some bits of code are better formatted manually (eg. because of the indenting rules in ReSharper, things like chained linq methods or multi-line ternary operators have a strange indent that pushes them way to the right). Is there any way to mark up parts of a file to tell ReSharper not to format that area? I'm hoping for some kind of markup similar to how ReSharper suppresses other warnings/features. If not, is there some way of changing a combination of settings to get ReSharper to format the indenting correctly? EDIT: I have found this post from the ReSharper forums that says that generated code sections (as defined in the ReSharper options page) are ignored in code cleanup. Having tried it though, it doesn't seem to get ignored.

  • Best way of implementing DropDownList in ASP.NET MVC 2?

    - by Kelsey
    I am trying to understand the best way of implementing a DropDownList in ASP.NET MVC 2 using the DropDownListFor helper. This is a multi-part question. First, what is the best way to pass the list data to the view? Pass the list in your model with a SelectList property that contains the data Pass the list in via ViewData How do I get a blank value in the DropDownList? Should I build it into the SelectList when I am creating it or is there some other means to tell the helper to auto create an empty value? Lastly, if for some reason there is a server side error and I need to redisplay the screen with the DropDownList, do I need to fetch the list values again to pass into the view model? This data is not maintained between posts (at least not when I pass it via my view model) so I was going to just fetch it again (it's cached). Am I going about this correctly?
