• So you want a French Site?

  - by juanlarios

  I thought I would write a quick write up of how to create a french site in SharePoint 2007. I'm not talking about a Variation but just a plain French Site from the ground up. There were some gotchas that I felt were worth blogging about. First:  go to Microsoft Telnet Article and follow the install instructions. Make sure that when you get to the download page that you select "French" as part of the drop down and you download and install the right language pack. I noticed that if you did not click the "change" button enven though I selected the 'french' language pack, it reverted back to the english language pack.   Second: You will notice a couple of things. When you go to central admin you will see the following:    Now you can pick between french site or english. You will get this if you install other language packs and they will be listed in the drop down. You will notice that you now have french headings and frech listings of sites. You see "Publishing" as a heading because I have a custom site definition that I deployed as a french site. Third: As you start navigating around and trying to create document libraries or sites you will start getting errors. Errors like the following: "Cannot make a cache safe URL for "SelectorControls.js", file not found. Please verify that the file exists under the layouts directory. " Troubleshoot issues with Windows SharePoint Services. Once you resolve the issue with this "js" file, you will find that there are other js files that are missing. The only problem is that if you are not fluent in French or the language you are trying to deploy, Well, you'll have a tough time understanding error messages as they will all be in the new language you are trying to deploy. So let's just talk about what happened when you installed the language pack. In the 12 Hive:  12/Template    you will now see a 1033 folder and a 1036 folder. The 1036 folder is the folder that was created and added as part of the language pack. What the above error is saying is that now that it's looking at the 1036 folder, well, it's missing some files. The nice thing is that these files are included in the 1033 folder (which is the English Language Pack). Simply copy and paste the controls from the one folder to the other. There will be more than one conflict so you will have to move serveral controls over. Can't remember how many but simply add them as error messages come up. I had to add some navigation controls and some content selectors.   Now that's all that you need to install the Frech Language pack anc reate site collections that are entirely in a another language. Do not mistake this with Variations, where you can have multiple language sites. For those of you doing a little bit extra with this, let me share what I was doing extra and what I needed to get it working for me. I had had a custom site definition which was obviously not showing up in my selection of french sites. I was under the impression that all sites in English would show up in french and that the sites were simply routed to a new Resource file for french content. And that is the case but there is a little extra that needs to be done if you have a custom site definition deployed:  First: Under hive 12/Template/1033/XML  there is a listing of site definition files that are deployed to the English side of things. If you navigate to 12/Template/1036/XML  and open one of the site definitions you will see that they are similar and reference the existing site definitions installed on the server, except that they have some french added to descriptions and names. Simply copy the xml file of your custom template to the 1036 folder to have it show up as a selection when you select French as the dropdown entry when create a site colleciton. You can go ahead and change the description and name to suit the language it's under.    Second: As part of my site definition, I packaed up several list templates, that were saved as STP files. When you navigate to the list template listing, well, the templates are for English sites, not French so I cannot create document libraries based on the template. What now? well here comes KWIzCom to the rescue! They seem to have put out a "STP language converter" where you can take a site template or list template and convert it to any target language you are after. It's a free download, Use it and you're good to go.  One thing I will mention is that when I convereted the English documents I whent ahead and converted them to French-Canadien. And it didn't work! so I finally figured out that the French Version it was expecting in the french site was "French-France". Don't know why that is, it's just what needs to be done to get that working. When I did that, I was able to use the List templates that I created in the English site for the French Site.   Hope it helps , good luck!

• Domain driven design value object, how to ensure a unique value

  - by Darren

  Hi, I am building a questionnaire creator. A questionnaire consists of sections, sections consist of pages and pages consist of questions. Questionnaire is the aggregate root. Sections, pages and questions can have what are called shortcodes which should be unique within a questionnaire (but not unique within the database hence they are not strictly an identity). I intended to make the shortcode a value object and wanted to include the business rule that it should be unique within the questionnaire but I am unsure how to ensure that. My understanding is that the value object should not access the repository or service layer so how does it find out if it is unique? Thanks for any help. Darren

• Why does MSBuild fail from the command line where VS2008 succeeds?

  - by sundeep

  I have an ASP.NET solution that builds just fine from within VS2008. However , it fails when i do this : MSBUILD.exe c:\path-to-sln It fails with a CS0006 error ("Metadata file 'dll_name' could not be found"). It also fails when I try with a .csproj of a project within the solution. What is VS2008 doing that MSBuild is missing ? It is my understanding that VS knows about inter assembly dependencies that MSBuild cant. Is there any way I can inform MSBuild of these? (I need MSBuild to work from the command line because I am calling it from an MSBuild-Task from within CruiseControl.Net.) Thanks in Advance. :3) (I have looked at http://stackoverflow.com/questions/280559/how-to-get-cmd-line-build-command-for-vs-solution , but still dont get it)

• Perl: implementing a dispatch table in an OO module?

  - by Iain

  I want to put some subs that are within an OO package into an array - also within the package - to use as a dispatch table. Something like this package Blah::Blah; use fields 'tests'; sub new { my($class )= @_; my $self = fields::new($class); $self->{'tests'} = [ $self->_sub1 ,$self->_sub2 ]; return $self; } _sub1 { ... }; _sub2 { ... }; I'm not entirely sure on the syntax for this? $self->{'tests'} = [ $self->_sub1 ,$self->_sub2 ]; or $self->{'tests'} = [ \&{$self->_sub1} ,\&{$self->_sub2} ]; or $self->{'tests'} = [ \&{_sub1} ,\&{_sub2} ]; I don't seem to be able to get this to work within an OO package, whereas it's quite straightforward in a procedural fashion, and I haven't found any examples for OO. Any help is much appreciated, Iain

• Server 2008 Web Edition IIS6 SMTP conflict

  - by user219313

  I'm using IIS6 Manager to setup the SMTP service on Windows Server 2008 Web Edition. Ignoring how mental this is, there seems to be a conflict (port 25?) which means that I cannot start and stop the Default SMTP server within IIS6. I can start and stop it with the services.msc snap in and this is reflected in state of the SMTP server in IIS6 manager. I'm worried that none of the settings I want to get at within IIS6 (logging, authentication etc..) are having any effect. None of these settings are available within IIS7 in Web Edition. Idiotic.

• Zip Code Radius Search question...

  - by KnockKnockWhosThere

  I'm wondering if it's possible to find all points by longitude and latitude within X radius of one point? So, if I provide a latitude/longitude of -76.0000, 38.0000, is it possible to simply find all the possible coordinates within (for example) a 10 mile radius of that? I know that there's a way to calculate the distance between two points, which is why I'm not clear as to whether this is possible... Because, it seems like you need to know the center coordinates (-76 and 38 in this case) as well as the coordinates of every other point in order to determine whether it falls within the specified radius... Is that right?

• StyleCop 4.4 works inside VS.NET 2010 but not MSBuild command line

  - by Steve Michelotti

  We are seeing extremely strange results where StyleCop will correctly report violations when run from within Visual Studio 2010. However, when we run msbuild on the command line (e.g., "MSBuild.exe mySolution.sln") it reports "No violations encountered" when clearly there are the same violations as when we ran it within Visual Studio. Is this a bug in the latest release of StyleCop? Or in the 2010 integration? Is there anything you can tell me about possible differences with StyleCop executing from within VS.NET versus MSBuild command line? Thanks.

• Why enumerator structs are a really bad idea

  - by Simon Cooper

  If you've ever poked around the .NET class libraries in Reflector, I'm sure you would have noticed that the generic collection classes all have implementations of their IEnumerator as a struct rather than a class. As you will see, this design decision has some rather unfortunate side effects... As is generally known in the .NET world, mutable structs are a Very Bad Idea; and there are several other blogs around explaining this (Eric Lippert's blog post explains the problem quite well). In the BCL, the generic collection enumerators are all mutable structs, as they need to keep track of where they are in the collection. This bit me quite hard when I was coding a wrapper around a LinkedList<int>.Enumerator. It boils down to this code: sealed class EnumeratorWrapper : IEnumerator<int> { private readonly LinkedList<int>.Enumerator m_Enumerator; public EnumeratorWrapper(LinkedList<int> linkedList) { m_Enumerator = linkedList.GetEnumerator(); } public int Current { get { return m_Enumerator.Current; } } object System.Collections.IEnumerator.Current { get { return Current; } } public bool MoveNext() { return m_Enumerator.MoveNext(); } public void Reset() { ((System.Collections.IEnumerator)m_Enumerator).Reset(); } public void Dispose() { m_Enumerator.Dispose(); } } The key line here is the MoveNext method. When I initially coded this, I thought that the call to m_Enumerator.MoveNext() would alter the enumerator state in the m_Enumerator class variable and so the enumeration would proceed in an orderly fashion through the collection. However, when I ran this code it went into an infinite loop - the m_Enumerator.MoveNext() call wasn't actually changing the state in the m_Enumerator variable at all, and my code was looping forever on the first collection element. It was only after disassembling that method that I found out what was going on The MoveNext method above results in the following IL: .method public hidebysig newslot virtual final instance bool MoveNext() cil managed { .maxstack 1 .locals init ( [0] bool CS$1$0000, [1] valuetype [System]System.Collections.Generic.LinkedList`1/Enumerator CS$0$0001) L_0000: nop L_0001: ldarg.0 L_0002: ldfld valuetype [System]System.Collections.Generic.LinkedList`1/Enumerator EnumeratorWrapper::m_Enumerator L_0007: stloc.1 L_0008: ldloca.s CS$0$0001 L_000a: call instance bool [System]System.Collections.Generic.LinkedList`1/Enumerator::MoveNext() L_000f: stloc.0 L_0010: br.s L_0012 L_0012: ldloc.0 L_0013: ret } Here, the important line is 0002 - m_Enumerator is accessed using the ldfld operator, which does the following: Finds the value of a field in the object whose reference is currently on the evaluation stack. So, what the MoveNext method is doing is the following: public bool MoveNext() { LinkedList<int>.Enumerator CS$0$0001 = this.m_Enumerator; bool CS$1$0000 = CS$0$0001.MoveNext(); return CS$1$0000; } The enumerator instance being modified by the call to MoveNext is the one stored in the CS$0$0001 variable on the stack, and not the one in the EnumeratorWrapper class instance. Hence why the state of m_Enumerator wasn't getting updated. Hmm, ok. Well, why is it doing this? If you have a read of Eric Lippert's blog post about this issue, you'll notice he quotes a few sections of the C# spec. In particular, 7.5.4: ...if the field is readonly and the reference occurs outside an instance constructor of the class in which the field is declared, then the result is a value, namely the value of the field I in the object referenced by E. And my m_Enumerator field is readonly! Indeed, if I remove the readonly from the class variable then the problem goes away, and the code works as expected. The IL confirms this: .method public hidebysig newslot virtual final instance bool MoveNext() cil managed { .maxstack 1 .locals init ( [0] bool CS$1$0000) L_0000: nop L_0001: ldarg.0 L_0002: ldflda valuetype [System]System.Collections.Generic.LinkedList`1/Enumerator EnumeratorWrapper::m_Enumerator L_0007: call instance bool [System]System.Collections.Generic.LinkedList`1/Enumerator::MoveNext() L_000c: stloc.0 L_000d: br.s L_000f L_000f: ldloc.0 L_0010: ret } Notice on line 0002, instead of the ldfld we had before, we've got a ldflda, which does this: Finds the address of a field in the object whose reference is currently on the evaluation stack. Instead of loading the value, we're loading the address of the m_Enumerator field. So now the call to MoveNext modifies the enumerator stored in the class rather than on the stack, and everything works as expected. Previously, I had thought enumerator structs were an odd but interesting feature of the BCL that I had used in the past to do linked list slices. However, effects like this only underline how dangerous mutable structs are, and I'm at a loss to explain why the enumerators were implemented as structs in the first place. (interestingly, the SortedList<TKey, TValue> enumerator is a struct but is private, which makes it even more odd - the only way it can be accessed is as a boxed IEnumerator!). I would love to hear people's theories as to why the enumerators are implemented in such a fashion. And bonus points if you can explain why LinkedList<int>.Enumerator.Reset is an explicit implementation but Dispose is implicit... Note to self: never ever ever code a mutable struct.

• Telerik is First to Announce Support for Microsoft Silverlight Analytics Framework

  Yesterday at MIX 10 conference Microsoft announced the Microsoft Silverlight Analytics Framework Beta. The Silverlight Analytics Framework (SAF) is a new open-source framework to allow designers and developers to integrate web analytics into Silverlight applications in a consistent manner. Supporting out-of-browser and offline scenarios, Microsoft built this framework in conjunction with a number of web analytics services and control vendors to support multiple analytics services simultaneously without degrading application performance. Because the SAF is enabled as a set of behaviors in Microsoft Expression Blend, designers and developers can visually instrument their designs and configure A/B testing rapidly without writing any code. Telerik is proud to be the first control vendor to support the Silverlight Analytics Framework. RadControls for Silverlight can be used with the framework out of the box. The suite offers Silverlight Analytics Framework handlers and behavior, helping developers to fine tune the values sent to the analytics providers. Because the analytics framework is using the Managed Extensibility Framework (MEF) for composition, you don't need to change the way you use the controls to benefit from the Telerik handlers. Just add a reference to the Telerik assemblies that contains the handlers. Here is the code that you need to declare to use RadTreeView: <UserControl x:Class="Telerik.SLAF.MainPage"         xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"         xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"         xmlns:i="clr-namespace:System.Windows.Interactivity;assembly=System.Windows.Interactivity"         xmlns:ga="clr-namespace:Google.WebAnalytics;assembly=Google.WebAnalytics"         xmlns:sa="clr-namespace:Microsoft.WebAnalytics.Behaviors;assembly=Microsoft.WebAnalytics.Behaviors"         xmlns:ic="clr-namespace:Microsoft.Expression.Interactivity.Core;assembly=Microsoft.Expression.Interactions"         xmlns:mc="http://schemas.openxmlformats.org/markup-compatibility/2006"         xmlns:telerikNavigation="clr-namespace:Telerik.Windows.Controls;assembly=Telerik.Windows.Controls.Navigation">        <Grid x:Name="LayoutRoot">         <i:Interaction.Behaviors>             <ga:GoogleAnalytics ProfileId="--Your GA ProfileId" Category="Demo" />         </i:Interaction.Behaviors>         <telerikNavigation:RadTreeView>             <i:Interaction.Triggers>                 <i:EventTrigger EventName="SelectionChanged">                     <sa:TrackAction />                 </i:EventTrigger>             </i:Interaction.Triggers>             <telerikNavigation:RadTreeViewItem Header="Item1">             </telerikNavigation:RadTreeViewItem>             <telerikNavigation:RadTreeViewItem Header="Item2" />             <telerikNavigation:RadTreeViewItem Header="Item3" />         </telerikNavigation:RadTreeView>     </Grid> </UserControl> Download the Telerik Microsoft Silverlight Analytics Framework Handlers and the sample project. This is our first Beta release - please drop us a line with any feedback you have or even better if you are at MIX10 - come visit us at the booth in the "Commons" hall so we can discuss it in person. Did you know that DotNetSlackers also publishes .net articles written by top known .net Authors? We already have over 80 articles in several categories including Silverlight. Take a look: here.

• How To Get Web Site Thumbnail Image In ASP.NET

  - by SAMIR BHOGAYTA

  Overview One very common requirement of many web applications is to display a thumbnail image of a web site. A typical example is to provide a link to a dynamic website displaying its current thumbnail image, or displaying images of websites with their links as a result of search (I love to see it on Google). Microsoft .NET Framework 2.0 makes it quite easier to do it in a ASP.NET application. Background In order to generate image of a web page, first we need to load the web page to get their html code, and then this html needs to be rendered in a web browser. After that, a screen shot can be taken easily. I think there is no easier way to do this. Before .NET framework 2.0 it was quite difficult to use a web browser in C# or VB.NET because we either have to use COM+ interoperability or third party controls which becomes headache later. WebBrowser control in .NET framework 2.0 In .NET framework 2.0 we have a new Windows Forms WebBrowser control which is a wrapper around old shwdoc.dll. All you really need to do is to drop a WebBrowser control from your Toolbox on your form in .NET framework 2.0. If you have not used WebBrowser control yet, it's quite easy to use and very consistent with other Windows Forms controls. Some important methods of WebBrowser control are. public bool GoBack(); public bool GoForward(); public void GoHome(); public void GoSearch(); public void Navigate(Uri url); public void DrawToBitmap(Bitmap bitmap, Rectangle targetBounds); These methods are self explanatory with their names like Navigate function which redirects browser to provided URL. It also has a number of useful overloads. The DrawToBitmap (inherited from Control) draws the current image of WebBrowser to the provided bitmap. Using WebBrowser control in ASP.NET 2.0 The Solution Let's start to implement the solution which we discussed above. First we will define a static method to get the web site thumbnail image. public static Bitmap GetWebSiteThumbnail(string Url, int BrowserWidth, int BrowserHeight, int ThumbnailWidth, int ThumbnailHeight) { WebsiteThumbnailImage thumbnailGenerator = new WebsiteThumbnailImage(Url, BrowserWidth, BrowserHeight, ThumbnailWidth, ThumbnailHeight); return thumbnailGenerator.GenerateWebSiteThumbnailImage(); } The WebsiteThumbnailImage class will have a public method named GenerateWebSiteThumbnailImage which will generate the website thumbnail image in a separate STA thread and wait for the thread to exit. In this case, I decided to Join method of Thread class to block the initial calling thread until the bitmap is actually available, and then return the generated web site thumbnail. public Bitmap GenerateWebSiteThumbnailImage() { Thread m_thread = new Thread(new ThreadStart(_GenerateWebSiteThumbnailImage)); m_thread.SetApartmentState(ApartmentState.STA); m_thread.Start(); m_thread.Join(); return m_Bitmap; } The _GenerateWebSiteThumbnailImage will create a WebBrowser control object and navigate to the provided Url. We also register for the DocumentCompleted event of the web browser control to take screen shot of the web page. To pass the flow to the other controls we need to perform a method call to Application.DoEvents(); and wait for the completion of the navigation until the browser state changes to Complete in a loop. private void _GenerateWebSiteThumbnailImage() { WebBrowser m_WebBrowser = new WebBrowser(); m_WebBrowser.ScrollBarsEnabled = false; m_WebBrowser.Navigate(m_Url); m_WebBrowser.DocumentCompleted += new WebBrowserDocument CompletedEventHandler(WebBrowser_DocumentCompleted); while (m_WebBrowser.ReadyState != WebBrowserReadyState.Complete) Application.DoEvents(); m_WebBrowser.Dispose(); } The DocumentCompleted event will be fired when the navigation is completed and the browser is ready for screen shot. We will get screen shot using DrawToBitmap method as described previously which will return the bitmap of the web browser. Then the thumbnail image is generated using GetThumbnailImage method of Bitmap class passing it the required thumbnail image width and height. private void WebBrowser_DocumentCompleted(object sender, WebBrowserDocumentCompletedEventArgs e) { WebBrowser m_WebBrowser = (WebBrowser)sender; m_WebBrowser.ClientSize = new Size(this.m_BrowserWidth, this.m_BrowserHeight); m_WebBrowser.ScrollBarsEnabled = false; m_Bitmap = new Bitmap(m_WebBrowser.Bounds.Width, m_WebBrowser.Bounds.Height); m_WebBrowser.BringToFront(); m_WebBrowser.DrawToBitmap(m_Bitmap, m_WebBrowser.Bounds); m_Bitmap = (Bitmap)m_Bitmap.GetThumbnailImage(m_ThumbnailWidth, m_ThumbnailHeight, null, IntPtr.Zero); } One more example here : http://www.codeproject.com/KB/aspnet/Website_URL_Screenshot.aspx

• Determining full XHR request URL on a Google Chrome XHR Breakpoint

  - by DanH

  I am initiating a jQuery ajax ($.ajax) post, within the Google Chrome browser. I have setup a XHR breakpoint in the "XHR Breakpoints" section of the "Scripts" tab within the Developer Tools. The criteria of the breakpoint is "get" ie. I want the debugger to break on all XHR requests which contain the word "get" in them (somePage.asmx/getListOfAnimals) is an example. The breakpoint is being correctly hit, however I am unable to determine what the exact URL that is being requested. I realize I can remove the breakpoint and see what URL is being requested from the "Network" tab, but I want to know this at the time the breakpoint is hit. I have tried stepping through the XHR request once it has been hit in Chrome, but I must be missing a Javascript object/property which contains the fully requested URL. Google Chrome has detected that the XHR requested URL contains "get" but how do I get to this URL from within the debug session before the request is made?

• C++ to bytecode compiler for Silverlight CLR?

  - by paleozogt

  I'd like to be able to compile a C/C++ library so that it runs within a safe managed runtime in the Silverlight CLR. There are several tools for doing this with the JVM that allows C++ code to run within a CRT emulation layer (see NestedVM, LLJVM, etc), which effectively allows C++ code to be run within a Java Applet. There's even a tool for this for the Adobe Flash VM (see Alchemy). However, I can't seem to find any tools like this for the CLR. fyi, the MSVC tools don't seem to allow for this: The /clr:pure flag will create C++ code that runs in the CLR, but it isn't safe (because the CRT isn't safe) and /clr:safe requires massive code changes (no native types, etc).

  Its been a month since I wrote my last post.  Much of work has been happening around planning for Tech Ed India, the upcoming Virtual TechDays this week as well as our Developer content at the Great Indian Developer Summit 2010.  Its going to be one exciting period starting this week and I am glad I would be able to meet a lot of folks who have written to me personally that they would like to catch up at Tech Ed India. For now, I had a chance to meet the Microsoft India Development Centre team that worked on the Microsoft Indic Language Input Tool (erstwhile Akshara). The team updated me that they have also released the scripts  so that the Indic input feature can be encapsulated into your own websites.  For example, if you are having a web page where you collect user information, you can pretty much make your site indic aware i.e. accept inputs in Tamil, Telugu, Kannada, Hindi etc.,  All you would need to include would be a bunch of scripts onto your web pages and you are ready to make it, like I said, “indic aware” I have built a sample web page that accepts First Name, Last Name, Address and an additional field.  When it comes to accepting indic, sometimes, you may want to avoid the indic input in certain fields and accept it in English.  You can specify the MicrosoftILITWebAttach="false" attribute to the Text Boxes and Text Areas (TextMode=”Multiline” in ASP.NET) so that the particular field automatically switches over to English input.  Similarly, the moment you specify that the TextMode=”Password” to make it as a password field, it automatically ignores all indic recognition and shows the masked dots for the words entered. Note that, this is, when we are going for the Opt-out mode, where we are specifying that by default all the input controls would need indic awareness and we would specify for those controls where it is not required.  The other mode is Opt-in mode where you would need to add a different property to the script definition i.e. attachMode=”optin” .  When we do this, we need to explicitly add the MicrosoftILITWebAttach="true" attribute for every control where we need indic input. I have created a sample web page which accepts First Name, Last Name, Address and an additional input field to demonstrate the “Opt-out”.   You can copy paste this into any of your web pages to check it <form id="form1" runat="server">     <!-- Microsoft Indic Language Input Tool embed code --> <input type="hidden" id="MicrosoftILITWebEmbedInfo" attachMode="optout" value="" /> <script type="text/javascript" src="http://ilit.microsoft.com/bookmarklet/script/Tamil.js" defer="defer"></script>     <div>     <h2>         Welcome to the Registration Page     </h2>     <p>         First Name: <asp:TextBox runat="server" ID="txtFirstName" />         <br />         <br />         Last Name: <asp:TextBox runat="server" ID="txtLastName" />         <br />         <br />         Password:         <asp:TextBox runat="server" ID="txtPassword" TextMode="Password" />         <br />         <br />         Address: <asp:TextBox runat="server" ID="txtAddress" TextMode="MultiLine" Height="100" Width="200" />         <br />         <br />         English Text: <asp:TextBox ID="txtEnglishText" runat="server" MicrosoftILITWebAttach="false" />     </p>     <p>         <!-- Microsoft Indic Language Input Tool attribution image link --> <a style="text-decoration: none" href="http://go.microsoft.com/fwlink/?LinkID=184205&clcid=0x409"><img style="border: 0px" alt="Transliteration by Microsoft" src="http://ilit.microsoft.com/bookmarklet/images/attribution.png"></a>     </p>     </div>     </form> If you note the code snippet above, I have included the scripts in the top with the attachMode set to “optout” and for the last TextBox, I have mentioned the MicrosoftILITWebAttach="false” attribute to make it accept English input.   Additionally, you also need to add the “Microsoft Indic Language Input Tool attribution image” to your web page as a courtesy to the team that developed this feature.  It would basically add a image saying “Transliteration by Microsoft” similar to a Copy Right image.  You can see the screen shot below where I have typed it in Tamil.  In that you will notice that the password field behaves as expected and the last field accepts English Text.  You can also notice the icon that comes in the first textbox that indicates that, the field is going to accept indic text.   This sample is using Tamil, but you can pretty much do it for Hindi, Telugu, Kannada, Marathi, Bengali etc.,   The website for getting the Indic script and other instructions is http://specials.msn.co.in/ilit/WebEmbed.aspx?language=Tamil You can replace the querystring value “Tamil” to other languages as mentioned above to get the respective script. This also works for plain HTML based websites and doesn’t necessarily need you to use ASP.NET to achieve the functionality. Note that, this form is not completely localized.  This is transliterated.  You can add label controls for FirstName, LastName indication etc., and use the Visual Studio tools to localize and get those values from resource files.  In the resource files, you can enter the text in different languages to make this a truly localized page.  If you just want to download the Indic Tool Desktop version (that can be used for typing in Word, Excel, pretty much any input area), you can download it from http://specials.msn.co.in/ilit/  In the same page, there is also a web version where you can type and get text then and there if you dont want to install the desktop version. So, go ahead, download / use them in your websites and enjoy the power of Indic. Cheers !!!

• How to get "paster request" to use config host value instead of localhost?

  - by mmartinez

  I'm trying to access my pylons application via cron job to send notifications to my users. The way I'm doing this is by running the application using something like: paster request myconfig.ini /maintenance/do In the actual controller I check for the "paste.command_request" to block public access. Everything works but the only problem is that within the notifications that I send to my users there is a link to their profile and the host is "localhost" which should instead be the domain name of the application. When the notifications are sent from within the served application (say, a user modifies their settings on the site) the notifications have the correct url. I am using mako to render my email tamplates and within the template I am using the "pylons.url" method with "qualified" set to "True". Am I missing something here? Thanks in advance.

• obj-c classes and sub classes (Cocos2d) conversion

  - by Lewis

  Hi I'm using this version of cocos2d: https://github.com/krzysztofzablocki/CCNode-SFGestureRecognizers Which supports the UIGestureRecognizer within a CCLayer in a cocos2d scene like so: @interface HelloWorldLayer : CCLayer <UIGestureRecognizerDelegate> { } Now I want to make this custom gesture work within the scene, attaching it to a sprite in cocos2d: #import <Foundation/Foundation.h> #import <UIKit/UIGestureRecognizerSubclass.h> @protocol OneFingerRotationGestureRecognizerDelegate <NSObject> @optional - (void) rotation: (CGFloat) angle;

} else if (angle < -180) { angle += 360; } // sum up single steps cumulatedAngle += angle; // call delegate if ([target respondsToSelector: @selector(rotation:)]) { [target rotation:angle]; } } else { // finger moved outside the area self.state = UIGestureRecognizerStateFailed; } } - (void)touchesEnded:(NSSet *)touches withEvent:(UIEvent *)event { [super touchesEnded:touches withEvent:event]; if (self.state == UIGestureRecognizerStatePossible) { self.state = UIGestureRecognizerStateRecognized; if ([target respondsToSelector: @selector(finalAngle:)]) { [target finalAngle:cumulatedAngle]; } } else { self.state = UIGestureRecognizerStateFailed; } cumulatedAngle = 0; } - (void)touchesCancelled:(NSSet *)touches withEvent:(UIEvent *)event { [super touchesCancelled:touches withEvent:event];

[self.view addGestureRecognizer: gestureRecognizer]; Now my question is, is it possible to add this custom gesture into the cocos2d project found on that github, and if so, what do I need to change in the OneFingerRotationGestureRecognizerDelegate to get it to work within cocos2d. Because at the minute it is setup in a standard iOS project and not a cocos2d project and I do not know enough about UIViews and classing/ sub classing in obj-c to get this to work. Also it seems to inherit from a UIView where cocos2d uses CCLayer. Kind regards, Lewis. I also realise I may have not included enough code from the custom gesture project for readers to interpret it fully, so the full project can be found here: https://github.com/melle/OneFingerRotationGestureDemo

• Composing Silverlight Applications With MEF

  - by PeterTweed

  Anyone who has written an application with complexity enough to warrant multiple controls on multiple pages/forms should understand the benefit of composite application development.  That is defining your application architecture that can be separated into separate pieces each with it’s own distinct purpose that can then be “composed” together into the solution. Composition can be useful in any layer of the application, from the presentation layer, the business layer, common services or data access.  Historically people have had different options to achieve composing applications from distinct well known pieces – their own version of dependency injection, containers to aid with composition like Unity, the composite application guidance for WPF and Silverlight and before that the composite application block. Microsoft has been working on another mechanism to aid composition and extension of applications for some time now – the Managed Extensibility Framework or MEF for short.  With Silverlight 4 it is part of the Silverlight environment.  MEF allows a much simplified mechanism for composition and extensibility compared to other mechanisms – which has always been the primary issue for adoption of the earlier mechanisms/frameworks. This post will guide you through the simple use of MEF for the scenario of composition of an application – using exports, imports and composition.  Steps: 1.     Create a new Silverlight 4 application. 2.     Add references to the following assemblies: System.ComponentModel.Composition.dll System.ComponentModel.Composition.Initialization.dll 3.     Add a new user control called LeftControl. 4.     Replace the LayoutRoot Grid with the following xaml:     <Grid x:Name="LayoutRoot" Background="Beige" Margin="40" >         <Button Content="Left Content" Margin="30"></Button>     </Grid> 5.     Add the following statement to the top of the LeftControl.xaml.cs file using System.ComponentModel.Composition; 6.     Add the following attribute to the LeftControl class     [Export(typeof(LeftControl))]   This attribute tells MEF that the type LeftControl will be exported – i.e. made available for other applications to import and compose into the application. 7.     Add a new user control called RightControl. 8.     Replace the LayoutRoot Grid with the following xaml:     <Grid x:Name="LayoutRoot" Background="Green" Margin="40"  >         <TextBlock Margin="40" Foreground="White" Text="Right Control" FontSize="16" VerticalAlignment="Center" HorizontalAlignment="Center" ></TextBlock>     </Grid> 9.     Add the following statement to the top of the RightControl.xaml.cs file using System.ComponentModel.Composition; 10.   Add the following attribute to the RightControl class     [Export(typeof(RightControl))] 11.   Add the following xaml to the LayoutRoot Grid in MainPage.xaml:         <StackPanel Orientation="Horizontal" HorizontalAlignment="Center">             <Border Name="LeftContent" Background="Red" BorderBrush="Gray" CornerRadius="20"></Border>             <Border Name="RightContent" Background="Red" BorderBrush="Gray" CornerRadius="20"></Border>         </StackPanel>   The borders will hold the controls that will be imported and composed via MEF. 12.   Add the following statement to the top of the MainPage.xaml.cs file using System.ComponentModel.Composition; 13.   Add the following properties to the MainPage class:         [Import(typeof(LeftControl))]         public LeftControl LeftUserControl { get; set; }         [Import(typeof(RightControl))]         public RightControl RightUserControl { get; set; }   This defines properties accepting LeftControl and RightControl types.  The attrributes are used to tell MEF the discovered type that should be applied to the property when composition occurs. 14.   Replace the MainPage constructore with the following code:         public MainPage()         {             InitializeComponent();             CompositionInitializer.SatisfyImports(this);             LeftContent.Child = LeftUserControl;             RightContent.Child = RightUserControl;         }   The CompositionInitializer.SatisfyImports(this) function call tells MEF to discover types related to the declared imports for this object (the MainPage object).  At that point, types matching those specified in the import defintions are discovered in the executing assembly location of the application and instantiated and assigned to the matching properties of the current object. 15.   Run the application and you will see the left control and right control types displayed in the MainPage:   Congratulations!  You have used MEF to dynamically compose user controls into a parent control in a composite application model. In the next post we will build on this topic to cover using MEF to compose Silverlight applications dynamically in download on demand scenarios – so .xap packages can be downloaded only when needed, avoiding large initial download for the main application xap.

• What does ruby include when it encounters the "include module" statement?

  - by Steve Weet

  If I have the following project structure project/ lib/ subproject/ a.rb b.rb lib.rb where lib.rb looks like this :- module subproject def foo do_some_stuff end end and a.rb and b.rb both need to mixin some methods within lib.rb and are both namespaced within a module like so :- require 'subproject/lib' module subproject class A include Subproject def initialize() foo() end end end What does ruby do when it encounters the include statement? How does it know that I want to only include the mixin from lib.rb rather than the whole module which includes both class A and class B, is this based purely on the require of subproject/lib or am I getting it wrong and it is including the whole of the module, including the definitions of Class A and B within themselves?

• Using an IBAction method when it is not called from an action?

  - by cannyboy

  Are there any issues when using IBAction when it is not actually called from a user's action? If you have an action like -(IBAction)sayHello:(id)sender; You can call it from within your class like: [self sayHello:@"x"] The @"x" doesn't do anything, it just fills in for the sender. You can actually create an IBAction method without (id)sender -(IBAction)sayHello; and call it from both user's actions and from within the code, but then you won't get any useful sender info from the interface. What's the 'correct' way of filling in for the sender, when calling from the code? And can you create sender info to send when it's called from within the code? Just trying to figure it out.

• Authentication for SaaS

  - by josh

  What would be recommended as an authentication solution for a Software-as-a-service product? Specifically, my product would have clients that would typically have low information technology skills, potentially not even having an IT department within their organization. I would still like to have my application authenticate against their internal directory service (eDirectory, Active Directory, etc.). I don't want them, however, to have to open/forward ports (for instance, opening up port 636 so I can do LDAPS binds directly to their directory service). One idea I had was to have an application installed on a server within their organization's network that would backconnect to my service. This would be a persistant socket. When I need to authenticate a user, I send the credentials via the socket (encrypted) - the application then performs a bind/whatever to authenticate against the directory service and replies with OK/FAIL. What would you suggest? My goal here is to essentially have the client install an application within their network, with very little configuration or intervention.

• Images not displayed in silverlight when app is run

  - by Sean

  I'm trying to display an image within a Silverlight application but the image does not display when the application is run. When creating the project within Visual Studio I chose the "Automatically generate a test page to host Silverlight at build time" option. Complete code as an example: <UserControl x:Class="SilverlightApplication3.Page" xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation" xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml" Width="400" Height="300"> <StackPanel> <Image Source="http://www.beachtownpress.com/db5/00415/beachtownpress.com/_uimages/beach7.jpg" /> </StackPanel> </UserControl> The application appears perfectly within Visual Studio, but when I run the application, the image does not display. Any ideas?

• Disable JavaScript on window.open

  - by sonofdelphi

  I have a set of (X)HTML files that I need to open with window.open() from an application homepage. I am able to open these files and read the data within them. function openFiles() { var files = document.querySelectorAll('td a'); //The list of files to scan is stored as links in an HTML table for(var i = 0; i<files.length; i++){ //Open each file in a browser window win = window.open(files[i].href); //Can I prevent the JavaScript in these files from executing? } } But the problem is that the scripts within the HTML files also get executed when opened like this. This is rather time-consuming and unnecessary; also, the scripts within those files may have side-effects. Is there a way to prevent JavaScript from executing on load?

  i am having problems with sorting can someone help to sort this table not just by its form entry id but onclick with some other columns i tried a lot of plugins but cant get anything to work and i dont know what to do i am new at this i sorry for my english thanks. here is the js: var Animals ={ index: window.localStorage.getItem("Animals:index"), $table: document.getElementById("animals-table"), $form: document.getElementById("animals-form"), $button_save: document.getElementById("animals-save"), $button_discard: document.getElementById("animals-discard"), init: function() { if (!Animals.index) { window.localStorage.setItem("Animals:index", Animals.index = 1); } Animals.$form.reset(); Animals.$button_discard.addEventListener("click", function(event) { Animals.$form.reset(); Animals.$form.id_entry.value = 0; }, true); Animals.$form.addEventListener("submit", function(event) { var entry = { id: parseInt(this.id_entry.value), animal_id:this.animal_id.value, animal_name: this.animal_name.value, animal_type: this.animal_type.value, bday: this.bday.value, animal_sex: this.animal_sex.value, mother_name: this.mother_name.value, farm_name: this.farm_name.value, money: this.money.value, weight: this.weight.value, purchase_partner: this.purchase_partner.value }; if (entry.id === 0) { Animals.storeAdd(entry); Animals.tableAdd(entry); } else { // edit Animals.storeEdit(entry); Animals.tableEdit(entry); } this.reset(); this.id_entry.value = 0; event.preventDefault(); }, true); if (window.localStorage.length - 1) { var animals_list = [], i, key; for (i = 0; i < window.localStorage.length; i++) { key = window.localStorage.key(i); if (/Animals:\d+/.test(key)) { animals_list.push(JSON.parse(window.localStorage.getItem(key))); } } if (animals_list.length) { animals_list.sort(function(a, b) {return a.id < b.id ? -1 : (a.id > b.id ? 1 : 0);}) .forEach(Animals.tableAdd);} Animals.$table.addEventListener("click", function(event) { var op = event.target.getAttribute("data-op"); if (/edit|remove/.test(op)) { var entry = JSON.parse(window.localStorage.getItem("Animals:"+ event.target.getAttribute("data- id"))); if (op == "edit") { Animals.$form.id_entry.value = entry.id; Animals.$form.animal_id.value = entry.animal_id; Animals.$form.animal_name.value = entry.animal_name; Animals.$form.animal_type.value = entry.animal_type; Animals.$form.bday.value = entry.bday; Animals.$form.animal_sex.value = entry.animal_sex; Animals.$form.mother_name.value = entry.mother_name; Animals.$form.farm_name.value = entry.farm_name; Animals.$form.money.value = entry.money; Animals.$form.weight.value = entry.weight; Animals.$form.purchase_partner.value = entry.purchase_partner; } else if (op == "remove") { if (confirm('Are you sure you want to remove this animal from your list?' )) { Animals.storeRemove(entry); Animals.tableRemove(entry); } } event.preventDefault(); } }, true); }, storeAdd: function(entry) { entry.id = Animals.index; window.localStorage.setItem("Animals:index", ++Animals.index); window.localStorage.setItem("Animals:"+ entry.id, JSON.stringify(entry)); }, storeEdit: function(entry) { window.localStorage.setItem("Animals:"+ entry.id, JSON.stringify(entry)); }, storeRemove: function(entry) { window.localStorage.removeItem("Animals:"+ entry.id); }, tableAdd: function(entry) { var $tr = document.createElement("tr"), $td, key; for (key in entry) { if (entry.hasOwnProperty(key)) { $td = document.createElement("td"); $td.appendChild(document.createTextNode(entry[key])); $tr.appendChild($td); } } $td = document.createElement("td"); $td.innerHTML = '<a data-op="edit" data-id="'+ entry.id +'">Edit</a> | <a data-op="remove" data-id="'+ entry.id +'">Remove</a>'; $tr.appendChild($td); $tr.setAttribute("id", "entry-"+ entry.id); Animals.$table.appendChild($tr); }, tableEdit: function(entry) { var $tr = document.getElementById("entry-"+ entry.id), $td, key; $tr.innerHTML = ""; for (key in entry) { if (entry.hasOwnProperty(key)) { $td = document.createElement("td"); $td.appendChild(document.createTextNode(entry[key])); $tr.appendChild($td); } } $td = document.createElement("td"); $td.innerHTML = '<a data-op="edit" data-id="'+ entry.id +'">Edit</a> | <a data-op="remove" data-id="'+ entry.id +'">Remove</a>'; $tr.appendChild($td); }, tableRemove: function(entry) { Animals.$table.removeChild(document.getElementById("entry-"+ entry.id)); } }; Animals.init();

• Expected specifier-qualifier-list before ... only in classes in a certain folder

  - by funkybro

  Hi Classes in my iPhone project are organised within folders on the filesystem, these correspond to groups (for each folder) in xcode. My problem is that there seems to be a particular class which classes in a particular group/folder cannot make reference to; the compiler complains of "Expected specifier-qualifier-list...". This happens on any class within this group, and also when I create a new class within this group and try and import the offending class like so: #import <Foundation/Foundation.h> #import "MyClass.h" @interface TryingToImport : NSObject { MyClass *myClass; // Expected specifier-qualifier-list before 'MyClass' } Creating an identical class in any other group works OK. I understand this error message is usually due to cyclical import references, I have checked over and over and there don't seem to be any of these. I assume I have inadvertantly configured the offending group to be different to the others in some way but I can't figure out how. Help please!

• Training a 'replacement', how to enforce standards?

  - by Mohgeroth

  Not sure that this is the right stack exchange site to ask this of, but here goes... Scope I work for a small company that employs a few hundred people. The development team for the company is small and works out of visual foxpro. A specific department in the company hired me in as a 'lone gunman' to fix and enhance a pre-existing invoicing system. I've successfully taken an Access application that suffered from a lot of risks and limitations and converted it into a C# application driven off of a SQL server backend. I have recently obtained my undergraduate and am no expert by any means. To help make up for that I've felt that earning microsoft certifications will force me to understand more about .net and how it functions. So, after giving my notice with 9 months in advance, 3 months ago a replacement finally showed up. Their role is to learn what I have been designing to an attempt to support the applications designed in C#. The Replacement Fresh out of college with no real-world work experience, the first instinct for anything involving data was and still is listboxes... any time data is mentioned the list box is the control of choice for the replacement. This has gotten to the point, no matter how many times I discuss other controls, where I've seen 5 listboxes on a single form. Classroom experience was almost all C++ console development. So, an example of where I have concern is in a winforms application: Users need to key Reasons into a table to select from later. Given that I know that a strongly typed data set exists, I can just drag the data source from the toolbox and it would create all of this for me. I realize this is a simple example but using databinding is the key. For the past few months now we have been talking about the strongly typed dataset, how to use it and where it interacts with other controls. Data sets, how they work in relation to binding sources, adapters and data grid views. After handing this project off I expected questions about how to implement these since for me this is the way to do it. What happened next simply floors me: An instance of an adapter from the strongly typed dataset was created in the activate event of the form, a table was created and filled with data. Then, a loop was made to manually add rows to a listbox from this table. Finally, a variable was kept to do lookups to figure out what ID the record was for updates if required. How do they modify records you ask? That was my first question too. You won't believe how simple it is, all you do it double click and they type into a pop-up prompt the new value to change it to. As a data entry operator, all the modal popups would drive me absolutely insane. The final solution exceeds 100 lines of code that must be maintained. So my concern is that none of this is sinking in... the department is only allowed 20 hours a week of their time. Up until last week, we've only been given 4-5 hours a week if I'm lucky. The past week or so, I've been lucky to get 10. Question WHAT DO I DO?! I have 4 weeks left until I leave and they fully 'support' this application. I love this job and the opportunity it has given me but it's time for me to spread my wings and find something new. I am in no way, shape or form convinced that they are ready to take over. I do feel that the replacement has the technical ability to 'figure it out' but instead of learning they just write code to do all of this stuff manually. If the replacement wants to code differently in the end, as long as it works I'm fine with that as horrifiying at it looks. However to support what I have designed they MUST to understand how it works and how I have used controls and the framework to make 'magic' happen. This project has about 40 forms, a database with over 30 some odd tables, triggers and stored procedures. It relates labor to invoices to contracts to projections... it's not as simple as it was three years ago when I began this project and the department is now in a position where they cannot survive without it. How in the world can I accomplish any of the following?: Enforce standards or understanding in constent design when the department manager keeps telling them they can do it however they want to Find a way to engage the replacement in active learning of the framework and system design that support must be given for Gracefully inform sr. management that 5-9 hours a week is simply not enough time to learn about the department, pre-existing processes, applications that need to be supported AND determine where potential enhancements to the system go... Yes I know this is a wall of text, thanks for reading through me but I simply don't know what I should be doing. For me, this job is a monster of a reference and things would look extremely bad if I left and things fell apart. How do I handle this?
