• Story of success: MySQL Enterprise Backup (MEB) was successfully integrated with IBM Tivoli Storage Manager (TSM) via System Backup to Tape (SBT) interface.

  - by user13334359

  Since version 3.6 MEB supports backups to tape through the SBT interface.The officially supported tool for such backups to tape is Oracle Secure Backup (OSB).But there are a lot of other Storage Managers. MEB allows to use them through the SBT interface. Since version 3.7 it also has option --sbt-environment which allows to pass environment variables, not needed by OSB, to third-party managers. At the same time MEB can not guarantee it would work with all of them.This month we were contacted by a customer who wanted to use IBM Tivoli Storage Manager (TSM) with MEB. We could only say them same thing I wrote in previous paragraph: this solution is supposed to work, but you have to be pioneers of this technology. And they agreed. They agreed to be the pioneers and so the story begins.MEB requires following options to be specified by those who want to connect it to SBT interface:--sbt-database-name: a name which should be handed over to SBT interface. This can be any name. Default, MySQL, works for most cases, so user is not required to specify this option.--sbt-lib-path: path to SBT library. For TSM this library comes with "Data Protection for Oracle", which, in its turn, interfaces with Oracle Recovery Manager (RMAN), which uses SBT interface. So you need to install it even if you don't use Oracle.--sbt-environment: environment for third-party manager. This option is not needed when you use OSB, but almost always necessary for third-party SBT managers. TSM requires variable TDPO_OPTFILE to be set and point to the TSM configuration file.--backup-image=sbt:: path to the image. Prefix "sbt:" indicates that image should be sent through SBT interfaceSo full command in our case would look like: ./mysqlbackup --port=3307 --protocol=tcp --user=backup_user --password=foobar \ --backup-image=sbt:my-first-backup --sbt-lib-path=/usr/lib/libobk.so \ --sbt-environment="TDPO_OPTFILE=/path/to/my/tdpo.opt" --backup-dir=/path/to/my/dir backup-to-imageAnd this command results in the following output log: MySQL Enterprise Backup version 3.7.1 [2012/02/16] Copyright (c) 2003, 2012, Oracle and/or its affiliates.

• Using Native Drag and Drop in HTML 5 pages

  - by nikolaosk

  This is going to be the eighth post in a series of posts regarding HTML 5. You can find the other posts here, here , here , here, here , here and here. In this post I will show you how to implement Drag and Drop functionality in an HTML 5 page using JQuery.This is a great functionality and we do not need to resort anymore to plugins like Silverlight and Flash to achieve this great feature. This is also called a native approach on Drag and Drop.I will use some events and I will write code to respond when these events are fired.As I said earlier we need to write Javascript to implement the drag and drop functionality. I will use the very popular JQuery Library. Please download the library (minified version) from http://jquery.com/downloadI will create a simple HTML page.There will be two thumbnails pics on it. There will also be the drag and drop area where the user will drag the thumb pics into it and they will resize to their actual size. The HTML markup for the page follows<!doctype html><html lang="en"><head><title>Liverpool Legends Gallery</title><meta charset="utf-8"><link rel="stylesheet" type="text/css" href="style.css"><script type="text/javascript" charset="utf-8" src="jquery-1.8.1.min.js"></script>  <script language="JavaScript" src="drag.js"></script>   </head><body><header><h1>A page dedicated to Liverpool Legends</h1><h2>Drag and Drop the thumb image in the designated area to see the full image</h2></header><div id="main"><img src="thumbs/steven-gerrard.jpg"  big="large-images/steven-gerrard-large.jpg" alt="John Barnes"><img src="thumbs/robbie-fowler.jpg" big="large-images/robbie-fowler-large.jpg" alt="Ian Rush"><div id="drag"><p>Drop your image here</p> </div></body></html> There is nothing difficult or fancy in the HTML markup above. I have a link to the external JQuery library and another javascript file that I will implement the whole drag and drop functionality.The code for the css file (style.css) follows#main{  float: left;  width: 340px;  margin-right: 30px;}#drag{  float: left;  width: 400px;  height:300px;  background-color: #c0c0c0;}These are simple CSS rules. This post cannot be a tutorial on CSS.For all these posts I assume that you have the basic HTML,CSS,Javascript skills.Now I am going to create a javascript file (drag.js) to implement the drag and drop functionality.I will provide the whole code for the drag.js file and then I will explain what I am doing in each step.$(function() {          var players = $('#main img');          players.attr('draggable', 'true');                    players.bind('dragstart', function(event) {              var data = event.originalEvent.dataTransfer;               var src = $(this).attr("big");              data.setData("Text", src);               return true;          });          var target = $('#drag');          target.bind('drop', function(event) {            var data = event.originalEvent.dataTransfer;            var src = ( data.getData('Text') );                         var img = $("<img></img>").attr("src", src);            $(this).html(img);            if (event.preventDefault) event.preventDefault();            return(false);          });                   target.bind('dragover', function(event) {                if (event.preventDefault) event.preventDefault();            return false;          });           players.bind('dragend', function(event) {             if (event.preventDefault) event.preventDefault();             return false;           });        });   In these lines var players = $('#main img'); players.attr('draggable', 'true');We grab all the images in the #main div and store them in a variable and then make them draggable.Then in following lines I am using the dragstart event.  players.bind('dragstart', function(event) {              var data = event.originalEvent.dataTransfer;               var src = $(this).attr("big");              data.setData("Text", src);               return true;          }); In this event I am associating the custom data attribute value with the item I am dragging.Then I create a variable to get hold of the dropping area var target = $('#drag'); Then in the following lines I implement the drop event and what happens when the user drops the image in the designated area on the page. target.bind('drop', function(event) {            var data = event.originalEvent.dataTransfer;            var src = ( data.getData('Text') );                         var img = $("<img></img>").attr("src", src);            $(this).html(img);            if (event.preventDefault) event.preventDefault();            return(false);          }); The dragend  event is fired when the user has finished the drag operation        players.bind('dragend', function(event) {             if (event.preventDefault) event.preventDefault();             return false;           }); When this method event.preventDefault() is called , the default action of the event will not be triggered.Please have a look a the picture below to see how the page looks before the drag and drop takes place. Then simply I drag and drop a picture in the dropping area.Have a look at the picture below It works!!! Hope it helps!!

• Matrix Multiplication with C++ AMP

  - by Daniel Moth

  As part of our API tour of C++ AMP, we looked recently at parallel_for_each. I ended that post by saying we would revisit parallel_for_each after introducing array and array_view. Now is the time, so this is part 2 of parallel_for_each, and also a post that brings together everything we've seen until now. The code for serial and accelerated Consider a naïve (or brute force) serial implementation of matrix multiplication  0: void MatrixMultiplySerial(std::vector<float>& vC, const std::vector<float>& vA, const std::vector<float>& vB, int M, int N, int W) 1: { 2: for (int row = 0; row < M; row++) 3: { 4: for (int col = 0; col < N; col++) 5: { 6: float sum = 0.0f; 7: for(int i = 0; i < W; i++) 8: sum += vA[row * W + i] * vB[i * N + col]; 9: vC[row * N + col] = sum; 10: } 11: } 12: } We notice that each loop iteration is independent from each other and so can be parallelized. If in addition we have really large amounts of data, then this is a good candidate to offload to an accelerator. First, I'll just show you an example of what that code may look like with C++ AMP, and then we'll analyze it. It is assumed that you included at the top of your file #include <amp.h> 13: void MatrixMultiplySimple(std::vector<float>& vC, const std::vector<float>& vA, const std::vector<float>& vB, int M, int N, int W) 14: { 15: concurrency::array_view<const float,2> a(M, W, vA); 16: concurrency::array_view<const float,2> b(W, N, vB); 17: concurrency::array_view<concurrency::writeonly<float>,2> c(M, N, vC); 18: concurrency::parallel_for_each(c.grid, 19: [=](concurrency::index<2> idx) restrict(direct3d) { 20: int row = idx[0]; int col = idx[1]; 21: float sum = 0.0f; 22: for(int i = 0; i < W; i++) 23: sum += a(row, i) * b(i, col); 24: c[idx] = sum; 25: }); 26: } First a visual comparison, just for fun: The beginning and end is the same, i.e. lines 0,1,12 are identical to lines 13,14,26. The double nested loop (lines 2,3,4,5 and 10,11) has been transformed into a parallel_for_each call (18,19,20 and 25). The core algorithm (lines 6,7,8,9) is essentially the same (lines 21,22,23,24). We have extra lines in the C++ AMP version (15,16,17). Now let's dig in deeper. Using array_view and extent When we decided to convert this function to run on an accelerator, we knew we couldn't use the std::vector objects in the restrict(direct3d) function. So we had a choice of copying the data to the the concurrency::array<T,N> object, or wrapping the vector container (and hence its data) with a concurrency::array_view<T,N> object from amp.h – here we used the latter (lines 15,16,17). Now we can access the same data through the array_view objects (a and b) instead of the vector objects (vA and vB), and the added benefit is that we can capture the array_view objects in the lambda (lines 19-25) that we pass to the parallel_for_each call (line 18) and the data will get copied on demand for us to the accelerator. Note that line 15 (and ditto for 16 and 17) could have been written as two lines instead of one: extent<2> e(M, W); array_view<const float, 2> a(e, vA); In other words, we could have explicitly created the extent object instead of letting the array_view create it for us under the covers through the constructor overload we chose. The benefit of the extent object in this instance is that we can express that the data is indeed two dimensional, i.e a matrix. When we were using a vector object we could not do that, and instead we had to track via additional unrelated variables the dimensions of the matrix (i.e. with the integers M and W) – aren't you loving C++ AMP already? Note that the const before the float when creating a and b, will result in the underling data only being copied to the accelerator and not be copied back – a nice optimization. A similar thing is happening on line 17 when creating array_view c, where we have indicated that we do not need to copy the data to the accelerator, only copy it back. The kernel dispatch On line 18 we make the call to the C++ AMP entry point (parallel_for_each) to invoke our parallel loop or, as some may say, dispatch our kernel. The first argument we need to pass describes how many threads we want for this computation. For this algorithm we decided that we want exactly the same number of threads as the number of elements in the output matrix, i.e. in array_view c which will eventually update the vector vC. So each thread will compute exactly one result. Since the elements in c are organized in a 2-dimensional manner we can organize our threads in a two-dimensional manner too. We don't have to think too much about how to create the first argument (a grid) since the array_view object helpfully exposes that as a property. Note that instead of c.grid we could have written grid<2>(c.extent) or grid<2>(extent<2>(M, N)) – the result is the same in that we have specified M*N threads to execute our lambda. The second argument is a restrict(direct3d) lambda that accepts an index object. Since we elected to use a two-dimensional extent as the first argument of parallel_for_each, the index will also be two-dimensional and as covered in the previous posts it represents the thread ID, which in our case maps perfectly to the index of each element in the resulting array_view. The kernel itself The lambda body (lines 20-24), or as some may say, the kernel, is the code that will actually execute on the accelerator. It will be called by M*N threads and we can use those threads to index into the two input array_views (a,b) and write results into the output array_view ( c ). The four lines (21-24) are essentially identical to the four lines of the serial algorithm (6-9). The only difference is how we index into a,b,c versus how we index into vA,vB,vC. The code we wrote with C++ AMP is much nicer in its indexing, because the dimensionality is a first class concept, so you don't have to do funny arithmetic calculating the index of where the next row starts, which you have to do when working with vectors directly (since they store all the data in a flat manner). I skipped over describing line 20. Note that we didn't really need to read the two components of the index into temporary local variables. This mostly reflects my personal choice, in some algorithms to break down the index into local variables with names that make sense for the algorithm, i.e. in this case row and col. In other cases it may i,j,k or x,y,z, or M,N or whatever. Also note that we could have written line 24 as: c(idx[0], idx[1])=sum  or  c(row, col)=sum instead of the simpler c[idx]=sum Targeting a specific accelerator Imagine that we had more than one hardware accelerator on a system and we wanted to pick a specific one to execute this parallel loop on. So there would be some code like this anywhere before line 18: vector<accelerator> accs = MyFunctionThatChoosesSuitableAccelerators(); accelerator acc = accs[0]; …and then we would modify line 18 so we would be calling another overload of parallel_for_each that accepts an accelerator_view as the first argument, so it would become: concurrency::parallel_for_each(acc.default_view, c.grid, ...and the rest of your code remains the same… how simple is that?

• Loosely coupled .NET Cache Provider using Dependency Injection

  - by Rhames

  I have recently been reading the excellent book “Dependency Injection in .NET”, written by Mark Seemann. I do not generally buy software development related books, as I never seem to have the time to read them, but I have found the time to read Mark’s book, and it was time well spent I think. Reading the ideas around Dependency Injection made me realise that the Cache Provider code I wrote about earlier (see http://geekswithblogs.net/Rhames/archive/2011/01/10/using-the-asp.net-cache-to-cache-data-in-a-model.aspx) could be refactored to use Dependency Injection, which should produce cleaner code. The goals are to: Separate the cache provider implementation (using the ASP.NET data cache) from the consumers (loose coupling). This will also mean that the dependency on System.Web for the cache provider does not ripple down into the layers where it is being consumed (such as the domain layer). Provide a decorator pattern to allow a consumer of the cache provider to be implemented separately from the base consumer (i.e. if we have a base repository, we can decorate this with a caching version). Although I used the term repository, in reality the cache consumer could be just about anything. Use constructor injection to provide the Dependency Injection, with a suitable DI container (I use Castle Windsor). The sample code for this post is available on github, https://github.com/RobinHames/CacheProvider.git ICacheProvider In the sample code, the key interface is ICacheProvider, which is in the domain layer. 1: using System; 2: using System.Collections.Generic; 3:   4: namespace CacheDiSample.Domain 5: { 6: public interface ICacheProvider<T> 7: { 8: T Fetch(string key, Func<T> retrieveData, DateTime? absoluteExpiry, TimeSpan? relativeExpiry); 9: IEnumerable<T> Fetch(string key, Func<IEnumerable<T>> retrieveData, DateTime? absoluteExpiry, TimeSpan? relativeExpiry); 10: } 11: }   This interface contains two methods to retrieve data from the cache, either as a single instance or as an IEnumerable. the second paramerter is of type Func<T>. This is the method used to retrieve data if nothing is found in the cache. The ASP.NET implementation of the ICacheProvider interface needs to live in a project that has a reference to system.web, typically this will be the root UI project, or it could be a separate project. The key thing is that the domain or data access layers do not need system.web references adding to them. In my sample MVC application, the CacheProvider is implemented in the UI project, in a folder called “CacheProviders”: 1: using System; 2: using System.Collections.Generic; 3: using System.Linq; 4: using System.Web; 5: using System.Web.Caching; 6: using CacheDiSample.Domain; 7:   8: namespace CacheDiSample.CacheProvider 9: { 10: public class CacheProvider<T> : ICacheProvider<T> 11: { 12: public T Fetch(string key, Func<T> retrieveData, DateTime? absoluteExpiry, TimeSpan? relativeExpiry) 13: { 14: return FetchAndCache<T>(key, retrieveData, absoluteExpiry, relativeExpiry); 15: } 16:   17: public IEnumerable<T> Fetch(string key, Func<IEnumerable<T>> retrieveData, DateTime? absoluteExpiry, TimeSpan? relativeExpiry) 18: { 19: return FetchAndCache<IEnumerable<T>>(key, retrieveData, absoluteExpiry, relativeExpiry); 20: } 21:   22: #region Helper Methods 23:   24: private U FetchAndCache<U>(string key, Func<U> retrieveData, DateTime? absoluteExpiry, TimeSpan? relativeExpiry) 25: { 26: U value; 27: if (!TryGetValue<U>(key, out value)) 28: { 29: value = retrieveData(); 30: if (!absoluteExpiry.HasValue) 31: absoluteExpiry = Cache.NoAbsoluteExpiration; 32:   33: if (!relativeExpiry.HasValue) 34: relativeExpiry = Cache.NoSlidingExpiration; 35:   36: HttpContext.Current.Cache.Insert(key, value, null, absoluteExpiry.Value, relativeExpiry.Value); 37: } 38: return value; 39: } 40:   41: private bool TryGetValue<U>(string key, out U value) 42: { 43: object cachedValue = HttpContext.Current.Cache.Get(key); 44: if (cachedValue == null) 45: { 46: value = default(U); 47: return false; 48: } 49: else 50: { 51: try 52: { 53: value = (U)cachedValue; 54: return true; 55: } 56: catch 57: { 58: value = default(U); 59: return false; 60: } 61: } 62: } 63:   64: #endregion 65:   66: } 67: }   The FetchAndCache helper method checks if the specified cache key exists, if it does not, the Func<U> retrieveData method is called, and the results are added to the cache. Using Castle Windsor to register the cache provider In the MVC UI project (my application root), Castle Windsor is used to register the CacheProvider implementation, using a Windsor Installer: 1: using Castle.MicroKernel.Registration; 2: using Castle.MicroKernel.SubSystems.Configuration; 3: using Castle.Windsor; 4:   5: using CacheDiSample.Domain; 6: using CacheDiSample.CacheProvider; 7:   8: namespace CacheDiSample.WindsorInstallers 9: { 10: public class CacheInstaller : IWindsorInstaller 11: { 12: public void Install(IWindsorContainer container, IConfigurationStore store) 13: { 14: container.Register( 15: Component.For(typeof(ICacheProvider<>)) 16: .ImplementedBy(typeof(CacheProvider<>)) 17: .LifestyleTransient()); 18: } 19: } 20: }   Note that the cache provider is registered as a open generic type. Consuming a Repository I have an existing couple of repository interfaces defined in my domain layer: IRepository.cs 1: using System; 2: using System.Collections.Generic; 3:   4: using CacheDiSample.Domain.Model; 5:   6: namespace CacheDiSample.Domain.Repositories 7: { 8: public interface IRepository<T> 9: where T : EntityBase 10: { 11: T GetById(int id); 12: IList<T> GetAll(); 13: } 14: }   IBlogRepository.cs 1: using System; 2: using CacheDiSample.Domain.Model; 3:   4: namespace CacheDiSample.Domain.Repositories 5: { 6: public interface IBlogRepository : IRepository<Blog> 7: { 8: Blog GetByName(string name); 9: } 10: }   These two repositories are implemented in the DataAccess layer, using Entity Framework to retrieve data (this is not important though). One important point is that in the BaseRepository implementation of IRepository, the methods are virtual. This will allow the decorator to override them. The BlogRepository is registered in a RepositoriesInstaller, again in the MVC UI project. 1: using Castle.MicroKernel.Registration; 2: using Castle.MicroKernel.SubSystems.Configuration; 3: using Castle.Windsor; 4:   5: using CacheDiSample.Domain.CacheDecorators; 6: using CacheDiSample.Domain.Repositories; 7: using CacheDiSample.DataAccess; 8:   9: namespace CacheDiSample.WindsorInstallers 10: { 11: public class RepositoriesInstaller : IWindsorInstaller 12: { 13: public void Install(IWindsorContainer container, IConfigurationStore store) 14: { 15: container.Register(Component.For<IBlogRepository>() 16: .ImplementedBy<BlogRepository>() 17: .LifestyleTransient() 18: .DependsOn(new 19: { 20: nameOrConnectionString = "BloggingContext" 21: })); 22: } 23: } 24: }   Now I can inject a dependency on the IBlogRepository into a consumer, such as a controller in my sample code: 1: using System; 2: using System.Collections.Generic; 3: using System.Linq; 4: using System.Web; 5: using System.Web.Mvc; 6:   7: using CacheDiSample.Domain.Repositories; 8: using CacheDiSample.Domain.Model; 9:   10: namespace CacheDiSample.Controllers 11: { 12: public class HomeController : Controller 13: { 14: private readonly IBlogRepository blogRepository; 15:   16: public HomeController(IBlogRepository blogRepository) 17: { 18: if (blogRepository == null) 19: throw new ArgumentNullException("blogRepository"); 20:   21: this.blogRepository = blogRepository; 22: } 23:   24: public ActionResult Index() 25: { 26: ViewBag.Message = "Welcome to ASP.NET MVC!"; 27:   28: var blogs = blogRepository.GetAll(); 29:   30: return View(new Models.HomeModel { Blogs = blogs }); 31: } 32:   33: public ActionResult About() 34: { 35: return View(); 36: } 37: } 38: }   Consuming the Cache Provider via a Decorator I used a Decorator pattern to consume the cache provider, this means my repositories follow the open/closed principle, as they do not require any modifications to implement the caching. It also means that my controllers do not have any knowledge of the caching taking place, as the DI container will simply inject the decorator instead of the root implementation of the repository. The first step is to implement a BlogRepository decorator, with the caching logic in it. Note that this can reside in the domain layer, as it does not require any knowledge of the data access methods. BlogRepositoryWithCaching.cs 1: using System; 2: using System.Collections.Generic; 3: using System.Linq; 4: using System.Text; 5:   6: using CacheDiSample.Domain.Model; 7: using CacheDiSample.Domain; 8: using CacheDiSample.Domain.Repositories; 9:   10: namespace CacheDiSample.Domain.CacheDecorators 11: { 12: public class BlogRepositoryWithCaching : IBlogRepository 13: { 14: // The generic cache provider, injected by DI 15: private ICacheProvider<Blog> cacheProvider; 16: // The decorated blog repository, injected by DI 17: private IBlogRepository parentBlogRepository; 18:   19: public BlogRepositoryWithCaching(IBlogRepository parentBlogRepository, ICacheProvider<Blog> cacheProvider) 20: { 21: if (parentBlogRepository == null) 22: throw new ArgumentNullException("parentBlogRepository"); 23:   24: this.parentBlogRepository = parentBlogRepository; 25:   26: if (cacheProvider == null) 27: throw new ArgumentNullException("cacheProvider"); 28:   29: this.cacheProvider = cacheProvider; 30: } 31:   32: public Blog GetByName(string name) 33: { 34: string key = string.Format("CacheDiSample.DataAccess.GetByName.{0}", name); 35: // hard code 5 minute expiry! 36: TimeSpan relativeCacheExpiry = new TimeSpan(0, 5, 0); 37: return cacheProvider.Fetch(key, () => 38: { 39: return parentBlogRepository.GetByName(name); 40: }, 41: null, relativeCacheExpiry); 42: } 43:   44: public Blog GetById(int id) 45: { 46: string key = string.Format("CacheDiSample.DataAccess.GetById.{0}", id); 47:   48: // hard code 5 minute expiry! 49: TimeSpan relativeCacheExpiry = new TimeSpan(0, 5, 0); 50: return cacheProvider.Fetch(key, () => 51: { 52: return parentBlogRepository.GetById(id); 53: }, 54: null, relativeCacheExpiry); 55: } 56:   57: public IList<Blog> GetAll() 58: { 59: string key = string.Format("CacheDiSample.DataAccess.GetAll"); 60:   61: // hard code 5 minute expiry! 62: TimeSpan relativeCacheExpiry = new TimeSpan(0, 5, 0); 63: return cacheProvider.Fetch(key, () => 64: { 65: return parentBlogRepository.GetAll(); 66: }, 67: null, relativeCacheExpiry) 68: .ToList(); 69: } 70: } 71: }   The key things in this caching repository are: I inject into the repository the ICacheProvider<Blog> implementation, via the constructor. This will make the cache provider functionality available to the repository. I inject the parent IBlogRepository implementation (which has the actual data access code), via the constructor. This will allow the methods implemented in the parent to be called if nothing is found in the cache. I override each of the methods implemented in the repository, including those implemented in the generic BaseRepository. Each override of these methods follows the same pattern. It makes a call to the CacheProvider.Fetch method, and passes in the parentBlogRepository implementation of the method as the retrieval method, to be used if nothing is present in the cache. Configuring the Caching Repository in the DI Container The final piece of the jigsaw is to tell Castle Windsor to use the BlogRepositoryWithCaching implementation of IBlogRepository, but to inject the actual Data Access implementation into this decorator. This is easily achieved by modifying the RepositoriesInstaller to use Windsor’s implicit decorator wiring: 1: using Castle.MicroKernel.Registration; 2: using Castle.MicroKernel.SubSystems.Configuration; 3: using Castle.Windsor; 4:   5: using CacheDiSample.Domain.CacheDecorators; 6: using CacheDiSample.Domain.Repositories; 7: using CacheDiSample.DataAccess; 8:   9: namespace CacheDiSample.WindsorInstallers 10: { 11: public class RepositoriesInstaller : IWindsorInstaller 12: { 13: public void Install(IWindsorContainer container, IConfigurationStore store) 14: { 15:   16: // Use Castle Windsor implicit wiring for the block repository decorator 17: // Register the outermost decorator first 18: container.Register(Component.For<IBlogRepository>() 19: .ImplementedBy<BlogRepositoryWithCaching>() 20: .LifestyleTransient()); 21: // Next register the IBlogRepository inmplementation to inject into the outer decorator 22: container.Register(Component.For<IBlogRepository>() 23: .ImplementedBy<BlogRepository>() 24: .LifestyleTransient() 25: .DependsOn(new 26: { 27: nameOrConnectionString = "BloggingContext" 28: })); 29: } 30: } 31: }   This is all that is needed. Now if the consumer of the repository makes a call to the repositories method, it will be routed via the caching mechanism. You can test this by stepping through the code, and seeing that the DataAccess.BlogRepository code is only called if there is no data in the cache, or this has expired. The next step is to add the SQL Cache Dependency support into this pattern, this will be a future post.

• Flex - Typed ArrayCollection as Horizontallist's dataprovider

  - by BS_C3

  Hi community! I have an ArrayCollection of objects. I'm passing this array to a horizontallist as a dataprovider and I'm using a custom itemRenderer. When executing the application, the horizontallist is displaying [object CustomClass][object CustomClass][object CustomClass][object CustomClass] I've tried casting each object in the itemrenderer as following: <mx:Label text="{(data as CustomClass).label1}"/> But it's not working... Thanks for any help you can provide. Regards, BS_C3 Edit - 09 March 2010 Let's go for some more code =) <?xml version="1.0" encoding="utf-8"?> <mx:Canvas xmlns:mx="http://www.adobe.com/2006/mxml"> <mx:Component id="Item"> <mx:VBox width="180"> <mx:HBox width="100%"> <mx:Spacer width="100%"/> <mx:Button label="x"/> </mx:HBox> <mx:Image id="thumbnail"/> <mx:Label width="100%" horizontalCenter="0" text="Collection"/> <mx:HBox width="100%"> <mx:Label width="100" text="GIA"/> <mx:Label text="{data.charg_st}"/> </mx:HBox> <mx:HBox width="100%"> <mx:Label width="100" text="Finger Size"/> <mx:Label text="xxxxxx"/> </mx:HBox> <mx:HBox width="100%"> <mx:Label width="100" text="Carat"/> <mx:Label text="{data.carats}"/> </mx:HBox> <mx:HBox width="100%"> <mx:Label width="100" text="Color"/> <mx:Label text="{data.color}"/> </mx:HBox> <mx:HBox width="100%"> <mx:Label width="100" text="Clarity"/> <mx:Label text="{data.clarity}"/> </mx:HBox> <mx:HBox width="100%"> <mx:Label width="100" text="Shop"/> <mx:Label text="{data.lgort_fp}"/> </mx:HBox> <mx:HBox width="100%"> <mx:Label width="100" text="Resizing"/> <mx:Label text="{data.resizing}"/> </mx:HBox> <mx:HBox width="100%"> <mx:Label width="100" text="Price Excl.

Now, the horizontallist is displaying empty items... with the correct width... The arraycollection is not empty (I'm using an alert on the click event on an item, and I do retrieve the expected data). Hope this will help _< Regards, BS_C3

• SMO ConnectionContext.StatementTimeout setting is ignored

  - by Woody

  I am successfully using Powershell with SMO to backup most databases. However, I have several large databases in which I receive a "timeout" error "System.Data.SqlClient.SqlException: Timeout expired". The timout consistently occurs at 10 minutes. I have tried setting ConnectionContext.StatementTimeout to 0, 6000, and to [System.Int32]::MaxValue. The setting made no difference. I have found a number of Google references which indicate setting it to 0 makes it unlimited. No matter what I try, the timeouts consistently occur at 10 minutes. I even set Remote Query Timeout on the server to 0 (via Studio Manager) to no avail. Below is my SMO connection where I set the time out and the actual backup function. Further below is the output from my script. UPDATE Interestingly enough, I wrote the backup function in C# using VS 2008 and the timeout override does work within that environment. I am in the process of incorporating that C# process into my Powershell Script until I can find out why the timeout override does not work with just Powershell. This is extremely annoying! function New-SMOconnection { Param ($server, $ApplicationName= "PowerShell SMO", [int]$StatementTimeout = 0 ) # Write-Debug "Function: New-SMOconnection $server $connectionname $commandtimeout" if (test-path variable:\conn) { $conn.connectioncontext.disconnect() } else { $conn = New-Object('Microsoft.SqlServer.Management.Smo.Server') $server } $conn.connectioncontext.applicationName = $applicationName $conn.ConnectionContext.StatementTimeout = $StatementTimeout $conn.connectioncontext.Connect() $conn } $smo = New-SMOConnection -server $server if ($smo.connectioncontext.isopen -eq $false) { Throw "Could not connect to server $($server)." } Function Backup-Database { Param([string]$dbname) $db = $smo.Databases.get_Item($dbname) if (!$db) {"Database $dbname was not found"; Return} $sqldir = $smo.Settings.BackupDirectory + "\$($smo.name -replace ("\\", "$"))" $s = ($server.Split('\'))[0] $basedir = "\\$s\" + $($sqldir -replace (":", "$")) $dt = get-date -format yyyyMMdd-HHmmss $dbbk = new-object ('Microsoft.SqlServer.Management.Smo.Backup') $dbbk.Action = 'Database' $dbbk.BackupSetDescription = "Full backup of " + $dbname $dbbk.BackupSetName = $dbname + " Backup" $dbbk.Database = $dbname $dbbk.MediaDescription = "Disk" $target = "$basedir\$dbname\FULL" if (-not(Test-Path $target)) { New-Item $target -ItemType directory | Out-Null} $device = "$sqldir\$dbname\FULL\" + $($server -replace("\\", "$")) + "_" + $dbname + "_FULL_" + $dt + ".bak" $dbbk.Devices.AddDevice($device, 'File') $dbbk.Initialize = $True $dbbk.Incremental = $false $dbbk.LogTruncation = [Microsoft.SqlServer.Management.Smo.BackupTruncateLogType]::Truncate If (!$copyonly) { If ($kill) {$smo.KillAllProcesses($dbname)} $dbbk.SqlBackupAsync($server) } $dbbk } Started SQL backups for server LCFSQLxxx\SQLxxx at 05/06/2010 15:33:16 Statement TimeOut value set to 0.

• Best practices for using the Entity Framework with WPF DataBinding

  - by Ken Smith

  I'm in the process of building my first real WPF application (i.e., the first intended to be used by someone besides me), and I'm still wrapping my head around the best way to do things in WPF. It's a fairly simple data access application using the still-fairly-new Entity Framework, but I haven't been able to find a lot of guidance online for the best way to use these two technologies (WPF and EF) together. So I thought I'd toss out how I'm approaching it, and see if anyone has any better suggestions. I'm using the Entity Framework with SQL Server 2008. The EF strikes me as both much more complicated than it needs to be, and not yet mature, but Linq-to-SQL is apparently dead, so I might as well use the technology that MS seems to be focusing on. This is a simple application, so I haven't (yet) seen fit to build a separate data layer around it. When I want to get at data, I use fairly simple Linq-to-Entity queries, usually straight from my code-behind, e.g.: var families = from family in entities.Family.Include("Person") orderby family.PrimaryLastName, family.Tag select family; Linq-to-Entity queries return an IOrderedQueryable result, which doesn't automatically reflect changes in the underlying data, e.g., if I add a new record via code to the entity data model, the existence of this new record is not automatically reflected in the various controls referencing the Linq query. Consequently, I'm throwing the results of these queries into an ObservableCollection, to capture underlying data changes: familyOC = new ObservableCollection<Family>(families.ToList()); I then map the ObservableCollection to a CollectionViewSource, so that I can get filtering, sorting, etc., without having to return to the database. familyCVS.Source = familyOC; familyCVS.View.Filter = new Predicate<object>(ApplyFamilyFilter); familyCVS.View.SortDescriptions.Add(new System.ComponentModel.SortDescription("PrimaryLastName", System.ComponentModel.ListSortDirection.Ascending)); familyCVS.View.SortDescriptions.Add(new System.ComponentModel.SortDescription("Tag", System.ComponentModel.ListSortDirection.Ascending)); I then bind the various controls and what-not to that CollectionViewSource: <ListBox DockPanel.Dock="Bottom" Margin="5,5,5,5" Name="familyList" ItemsSource="{Binding Source={StaticResource familyCVS}, Path=., Mode=TwoWay}" IsSynchronizedWithCurrentItem="True" ItemTemplate="{StaticResource familyTemplate}" SelectionChanged="familyList_SelectionChanged" /> When I need to add or delete records/objects, I manually do so from both the entity data model, and the ObservableCollection: private void DeletePerson(Person person) { entities.DeleteObject(person); entities.SaveChanges(); personOC.Remove(person); } I'm generally using StackPanel and DockPanel controls to position elements. Sometimes I'll use a Grid, but it seems hard to maintain: if you want to add a new row to the top of your grid, you have to touch every control directly hosted by the grid to tell it to use a new line. Uggh. (Microsoft has never really seemed to get the DRY concept.) I almost never use the VS WPF designer to add, modify or position controls. The WPF designer that comes with VS is sort of vaguely helpful to see what your form is going to look like, but even then, well, not really, especially if you're using data templates that aren't binding to data that's available at design time. If I need to edit my XAML, I take it like a man and do it manually. Most of my real code is in C# rather than XAML. As I've mentioned elsewhere, entirely aside from the fact that I'm not yet used to "thinking" in it, XAML strikes me as a clunky, ugly language, that also happens to come with poor designer and intellisense support, and that can't be debugged. Uggh. Consequently, whenever I can see clearly how to do something in C# code-behind that I can't easily see how to do in XAML, I do it in C#, with no apologies. There's been plenty written about how it's a good practice to almost never use code-behind in WPF page (say, for event-handling), but so far at least, that makes no sense to me whatsoever. Why should I do something in an ugly, clunky language with god-awful syntax, an astonishingly bad editor, and virtually no type safety, when I can use a nice, clean language like C# that has a world-class editor, near-perfect intellisense, and unparalleled type safety? So that's where I'm at. Any suggestions? Am I missing any big parts of this? Anything that I should really think about doing differently?

• How can I use the Boost Graph Library to lay out verticies?

• How to pass user-defined structs using boost mpi

  - by lava

  I am trying to send a user-defined structure named ABC using boost::mpi::send () call. The given struct contains a vector "data" whose size is determined at runtime. Objects of struct ABC are sent by master to slaves. But the slaves need to know the size of vector "data" so that the sufficient buffer is available on the slave to receive this data. I can work around it by sending the size first and initialize sufficient buffer on the slave before receiving the objects of struct ABC. But that defeats the whole purpose of using STL containers. Does anyone know of a better way to do handle this ? Any suggestions are greatly appreciated. Here is a sample code that describes the intent of my program. This code fails at runtime due to above mentioned reason. struct ABC { double cur_stock_price; double strike_price; double risk_free_rate; double option_price; std::vector <char> data; }; namespace boost { namespace serialization { template<class Archive> void serialize (Archive &ar, struct ABC &abc, unsigned int version) { ar & abc.cur_stock_price; ar & abc.strike_price; ar & abc.risk_free_rate; ar & abc.option_price; ar & bopr.data; } } } BOOST_IS_MPI_DATATYPE (ABC); int main(int argc, char* argv[]) { mpi::environment env (argc, argv); mpi::communicator world; if (world.rank () == 0) { ABC abc_obj; abc.cur_stock_price = 1.0; abc.strike_price = 5.0; abc.risk_free_rate = 2.5; abc.option_price = 3.0; abc_obj.data.push_back ('a'); abc_obj.data.push_back ('b'); world.send ( 1, ANY_TAG, abc_obj;); std::cout << "Rank 0 OK!" << std::endl; } else if (world.rank () == 1) { ABC abc_obj; // Fails here because abc_obj is not big enough world.recv (0,ANY_TAG, abc_obj;); std::cout << "Rank 1 OK!" << std::endl; for (int i = 0; i < abc_obj;.data.size(); i++) std::cout << i << "=" << abc_obj.data[i] << std::endl; } MPI_Finalize(); return 0; }

• TableView Cells Use Whole Screen Height

  - by Kyle

  I read through this tutorial Appcelerator: Using JSON to Build a Twitter Client and attempted to create my own simple application to interact with a Jetty server I setup running some Spring code. I basically call a get http request that gives me a bunch of contacts in JSON format. I then populate several rows with my JSON data and try to build a TableView. All of that works, however, my tableView rows take up the whole screen. Each row is one screen. I can scroll up and down and see all my data, but I'm trying to figure out what's wrong in my styling that's making the cells use the whole screen. My CSS is not great, so any help is appreciated. Thanks! Here's my js file that's loading the tableView: // create variable "win" to refer to current window var win = Titanium.UI.currentWindow; // Function loadContacts() function loadContacts() { // empty array "rowData" for table view cells var rowData = []; // create http client var loader = Titanium.Network.createHTTPClient(); // set http request method and url loader.setRequestHeader("Accept", "application/json"); loader.open("GET", "http://localhost:8080/contactsample/contacts"); // run the function when the data is ready for us to process loader.onload = function(){ Ti.API.debug("JSON Data: " + this.responseText); // evaluate json var contacts = JSON.parse(this.responseText); for(var i=0; i < contacts.length; i++) { var id = contacts[i].id; Ti.API.info("JSON Data, Row[" + i + "], ID: " + contacts[i].id); var name = contacts[i].name; Ti.API.info("JSON Data, Row[" + i + "], Name: " + contacts[i].name); var phone = contacts[i].phone; Ti.API.info("JSON Data, Row[" + i + "], Phone: " + contacts[i].phone); var address = contacts[i].address; Ti.API.info("JSON Data, Row[" + i + "], Address: " + contacts[i].address); // create row var row = Titanium.UI.createTableViewRow({ height:'auto' }); // create row's view var contactView = Titanium.UI.createView({ height:'auto', layout:'vertical', top:5, right:5, bottom:5, left:5 }); var nameLbl = Titanium.UI.createLabel({ text:name, left:5, height:24, width:236, textAlign:'left', color:'#444444', font:{ fontFamily:'Trebuchet MS', fontSize:16, fontWeight:'bold' } }); var phoneLbl = Titanium.UI.createLabel({ text: phone, top:0, bottom:2, height:'auto', width:236, textAlign:'right', font:{ fontSize:14} }); var addressLbl = Titanium.UI.createLabel({ text: address, top:0, bottom:2, height:'auto', width:236, textAlign:'right', font:{ fontSize:14} }); contactView.add(nameLbl); contactView.add(phoneLbl); contactView.add(addressLbl); row.add(contactView); row.className = "item" + i; rowData.push(row); } Ti.API.info("RowData: " + rowData); // create table view var tableView = Titanium.UI.createTableView( { data: rowData }); win.add(tableView); }; // send request loader.send(); } // get contacts loadContacts(); And here are some screens showing my problem.

• AT91SAM7X512's SPI peripheral gets disabled on write to SPI_TDR

  - by Dor

  My AT91SAM7X512's SPI peripheral gets disabled on the X time (X varies) that I write to SPI_TDR. As a result, the processor hangs on the while loop that checks the TDRE flag in SPI_SR. This while loop is located in the function SPI_Write() that belongs to the software package/library provided by ATMEL. The problem occurs arbitrarily - sometimes everything works OK and sometimes it fails on repeated attempts (attemp = downloading the same binary to the MCU and running the program). Configurations are (defined in the order of writing): SPI_MR: MSTR = 1 PS = 0 PCSDEC = 0 PCS = 0111 DLYBCS = 0 SPI_CSR[3]: CPOL = 0 NCPHA = 1 CSAAT = 0 BITS = 0000 SCBR = 20 DLYBS = 0 DLYBCT = 0 SPI_CR: SPIEN = 1 After setting the configurations, the code verifies that the SPI is enabled, by checking the SPIENS flag. I perform a transmission of bytes as follows: const short int dataSize = 5; // Filling array with random data unsigned char data[dataSize] = {0xA5, 0x34, 0x12, 0x00, 0xFF}; short int i = 0; volatile unsigned short dummyRead; SetCS3(); // NPCS3 == PIOA15 while(i-- < dataSize) { mySPI_Write(data[i]); while((AT91C_BASE_SPI0->SPI_SR & AT91C_SPI_TXEMPTY) == 0); dummyRead = SPI_Read(); // SPI_Read() from Atmel's library } ClearCS3(); /**********************************/ void mySPI_Write(unsigned char data) { while ((AT91C_BASE_SPI0->SPI_SR & AT91C_SPI_TXEMPTY) == 0); AT91C_BASE_SPI0->SPI_TDR = data; while ((AT91C_BASE_SPI0->SPI_SR & AT91C_SPI_TDRE) == 0); // <-- This is where // the processor hangs, because that the SPI peripheral is disabled // (SPIENS equals 0), which makes TDRE equal to 0 forever. } Questions: What's causing the SPI peripheral to become disabled on the write to SPI_TDR? Should I un-comment the line in SPI_Write() that reads the SPI_RDR register? Means, the 4th line in the following code: (The 4th line is originally marked as a comment) void SPI_Write(AT91S_SPI *spi, unsigned int npcs, unsigned short data) { // Discard contents of RDR register //volatile unsigned int discard = spi->SPI_RDR; /* Send data */ while ((spi->SPI_SR & AT91C_SPI_TXEMPTY) == 0); spi->SPI_TDR = data | SPI_PCS(npcs); while ((spi->SPI_SR & AT91C_SPI_TDRE) == 0); } Is there something wrong with the code above that transmits 5 bytes of data? Please note: The NPCS line num. 3 is a GPIO line (means, in PIO mode), and is not controlled by the SPI controller. I'm controlling this line by myself in the code, by de/asserting the ChipSelect#3 (NPCS3) pin when needed. The reason that I'm doing so is because that problems occurred while trying to let the SPI controller to control this pin. I didn't reset the SPI peripheral twice, because that the errata tells to reset it twice only if I perform a reset - which I don't do. Quoting the errata: If a software reset (SWRST in the SPI Control Register) is performed, the SPI may not work properly (the clock is enabled before the chip select.) Problem Fix/Workaround The SPI Control Register field, SWRST (Software Reset) needs to be written twice to be cor- rectly set. I noticed that sometimes, if I put a delay before the write to the SPI_TDR register (in SPI_Write()), then the code works perfectly and the communications succeeds. Useful links: AT91SAM7X Series Preliminary.pdf ATMEL software package/library spi.c from Atmel's library spi.h from Atmel's library An example of initializing the SPI and performing a transfer of 5 bytes is highly appreciated and helpful.

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

  - by Thomas Scattolin

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

• How to load and pass a Xforms form in Orbeon (How to Send instance to XForms) ?

  - by Clem

  Hi, I am using the Orbeon Forms solution to generate messages from filled-in web forms. I read different code snippetse in Orbeon's wiki on XForms submission from a pipeline, and I tried different solutions but it doesn't work, and there is no example with a POST from a pipeline, caught by a PFC and sent to an XForms view that receives the posted data (all examples are done in the same page). I have the following pipeline which is received on his instance input: pipelineWrite.xpl <p:config ...> <p:param name="instance" type="input"/> <!-- instance containing the data of the form filled by user --> <p:param name="data" type="output"/> <p:processor name="oxf:java"> <!-- transforms the data into a file --> <p:input name="config"> <config sourcepath="." class="ProcessorWriteCUSDECCD001B"/> </p:input> <p:input name="input" href="#instance"/> <p:output name="output" id="file"/> <!-- XML containing the url of the file --> </p:processor> <p:processor name="oxf:xforms-submission"> <!-- post the XML to the success view --> <p:input name="submission"> <xforms:submission method="post" action="/CUSDECCD001B/success" /> </p:input> <p:input name="request" href="#file"/> <p:output name="response" ref="data"/> </p:processor> </p:config> Then there is the PFC which catch the actions : page-flow.xml <config xmlns="http://www.orbeon.com/oxf/controller"> <page path-info="/CUSDECCD001B/" view="View/ViewForm.xhtml"/> <!-- load the form to be filled in by user --> <page path-info="/CUSDECCD001B/write" model="Controller/PipelineWrite.xpl"/> <!-- send the instance of the form filled to the pipeline above --> <page path-info="/CUSDECCD001B/success" view="View/ViewSuccess.xhtml"/> <!-- send the instance containing the url of the file to the success view --> <epilogue url="oxf:/config/epilogue.xpl"/> </config> Then there is the success view, which is very simple : ViewSuccess.xhtml <html ... > <head> <title>Generation OK</title> <xforms:model> <xforms:instance id="FILE" src="input:instance"> <files xmlns=""> <file mediaType="" filename="" size="" /> </files> </xforms:instance> </xforms:model> </head> <body> Click here to download : <xforms:output ref="//file" appearance="xxforms:download"> <xforms:filename ref="@filename"/> <xforms:mediatype ref="@mediatype"/> <xforms:label>Download</xforms:label> </xforms:output> </body> </html> The problem is that the post is done well, the PFC catches the action well, load the correct view, but the view is loaded with no data (the view doesn't find the data on his instance input). I tried with a GET in the view to retrieve the POST data, and that's the same thing. No data is retrieved. So the download button doesn't work. I hope I'm clear enough to find a solution. Thanks in advance.

• Analyzing bitmaps produced by NSAffineTransform and CILineOverlay filters

  - by Adam

  I am trying to manipulate an image using a chain of CIFilters, and then examine each byte of the resulting image (bitmap). Long term, I do not need to display the resulting image (bitmap) -- I just need to "analyze" it in memory. But near-term I am displaying it on screen, to help with debugging. I have some "bitmap examination" code that works as expected when examining the NSImage (bitmap representation) I use as my input (loaded from a JPG file into an NSImage). And it SOMETIMES works as expected when I use it on the outputBitmap produced by the code below. More specifically, when I use an NSAffineTransform filter to create outputBitmap, then outputBitmap contains the data I would expect. But if I use a CILineOverlay filter to create the outputBitmap, none of the bytes in the bitmap have any data in them. I believe both of these filters are working as expected, because when I display their results on screen (via outputImageView), they look "correct." Yet when I examine the outputBitmaps, the one created from the CILineOverlay filter is "empty" while the one created from NSAffineTransfer contains data. Furthermore, if I chain the two filters together, the final resulting bitmap only seems to contain data if I run the AffineTransform last. Seems very strange, to me??? My understanding (from reading the CI programming guide) is that the CIImage should be considered an "image recipe" rather than an actual image, because the image isn't actually created until the image is "drawn." Given that, it would make sense that the CIimage bitmap doesn't have data -- but I don't understand why it has data after I run the NSAffineTransform but doesn't have data after running the CILineOverlay transform? Basically, I am trying to determine if creating the NSCIImageRep (ir in the code below) from the CIImage (myResult) is equivalent to "drawing" the CIImage -- in other words if that should force the bitmap to be populated? If someone knows the answer to this please let me know -- it will save me a few hours of trial and error experimenting! Finally, if the answer is "you must draw to a graphics context" ... then I have another question: would I need to do something along the lines of what is described in the Quartz 2D Programming Guide: Graphics Contexts, listing 2-7 and 2-8: drawing to a bitmap graphics context? That is the path down which I am about to head ... but it seems like a lot of code just to force the bitmap data to be dumped into an array where I can get at it. So if there is an easier or better way please let me know. I just want to take the data (that should be) in myResult and put it into a bitmap array where I can access it at the byte level. And since I already have code that works with an NSBitmapImageRep, unless doing it that way is a bad idea for some reason that is not readily apparent to me, then I would prefer to "convert" myResult into an NSBitmapImageRep. CIImage * myResult = [transform valueForKey:@"outputImage"]; NSImage *outputImage; NSCIImageRep *ir = [NSCIImageRep alloc]; ir = [NSCIImageRep imageRepWithCIImage:myResult]; outputImage = [[[NSImage alloc] initWithSize: NSMakeSize(inputImage.size.width, inputImage.size.height)] autorelease]; [outputImage addRepresentation:ir]; [outputImageView setImage: outputImage]; NSBitmapImageRep *outputBitmap = [[NSBitmapImageRep alloc] initWithCIImage: myResult]; Thanks, Adam

• Internet Explorer ajax request not returning anything

  - by Ryan Giglio

  At the end of my registration process you get to a payment screen where you can enter a coupon code, and there is an AJAX call which fetches the coupon from the database and returns it to the page so it can be applied to your total before it is submitted to paypal. It works great in Firefox, Chrome, and Safari, but in Internet Explorer, nothing happens. The (data) being returned to the jQuery function appears to be null. jQuery Post function applyPromo() { var enteredCode = $("#promoCode").val(); $(".promoDiscountContainer").css("display", "block"); $(".promoDiscount").html("<img src='/images/loading.gif' alt='Loading...' title='Loading...' height='18' width='18' />"); $.post("/ajax/lookup-promo.php", { promoCode : enteredCode }, function(data){ if ( data != "error" ) { var promoType = data.getElementsByTagName('promoType').item(0).childNodes.item(0).data; var promoAmount = data.getElementsByTagName('promoAmount').item(0).childNodes.item(0).data; $(".promoDiscountContainer").css("display", "block"); $(".totalWithPromoContainer").css("display", "block"); if (promoType == "percent") { $("#promoDiscount").html("-" + promoAmount + "%"); var newPrice = (originalPrice - (originalPrice * (promoAmount / 100))); $("#totalWithPromo").html(" $" + newPrice); if ( promoAmount == 100 ) { skipPayment(); } } else { $("#promoDiscount").html("-$" + promoAmount); var newPrice = originalPrice - promoAmount; $("#totalWithPromo").html(" $" + newPrice); } $("#paypalPrice").val(newPrice + ".00"); $("#promoConfirm").css("display", "none"); $("#promoConfirm").html("Promotion Found"); finalPrice = newPrice; } else { $(".promoDiscountContainer").css("display", "none"); $(".totalWithPromoContainer").css("display", "none"); $("#promoDiscount").html(""); $("#totalWithPromo").html(""); $("#paypalPrice").val(originalPrice + ".00"); $("#promoConfirm").css("display", "block"); $("#promoConfirm").html("Promotion Not Found"); finalPrice = originalPrice; } }, "xml"); } Corresponding PHP Page include '../includes/dbConn.php'; $enteredCode = $_POST['promoCode']; $result = mysql_query( "SELECT * FROM promotion WHERE promo_code = '" . $enteredCode .

• Website Link Injection

  - by Ryan B

  I have a website that is fairly static. It has some forms on it to send in contact information, mailing list submissions, etc. Perhaps hours/days after an upload to the site I found that the main index page had new code in it that I had not placed there that contained a hidden bunch of links in a invisible div. I have the following code the handles the variables sent in from the form. <?php // PHP Mail Order to [email protected] w/ some error detection. $jamemail = "[email protected]"; function check_input($data, $problem='') { $data = trim($data); $data = stripslashes($data); $data = htmlspecialchars($data); if ($problem && strlen($data) == 0) { die($problem); } return $data; } $email = check_input($_POST['email'], "Please input email address."); $name = check_input($_POST['name'], "Please input name."); mail($jamemail, "Mailing List Submission", "Name: " . $name . " Email: " .$email); header('Location: index.php'); ?> I have the following code within the index page to present the form with some Javascript to do error detection on the content of the submission prior to submission. <form action="sendlist.php" method="post" onSubmit="return checkmaill(this);"> <label for="name"><strong>Name: </strong></label> <input type="text" name="name"/><br /> <label for="email"><strong>Email: </strong></label> <input type="text" name="email"/><br /> &nbsp;&nbsp;&nbsp;&nbsp;&nbsp;<input type="submit" value="Subscribe" style="width: 100px;"/> </form> At the end of the day, the source code where the injected hyperlinks is as follows: </body> </html><!-- google --><font style="position: absolute;overflow: hidden;height: 0;width: 0"> xeex172901 <a href=http://menorca.caeb.com/od9c2/xjdmy/onondaga.php>onondaga</a> <a href=http://menorca.caeb.com/od9c2/xjdmy/tami.php>tami</a> <a href=http://menorca.caeb.com/od9c2/xjdmy/shotguns.php>shotguns</a> <a href=http://menorca.caeb.com/od9c2/xjdmy/weir.php>weir</a> <a href=http://menorca.caeb.com/od9c2/xjdmy/copperhead.php>copperhead</a> <a href=http://menorca.caeb.com/od9c2/xjdmy/mpv.php>mpv</a> <a href=http://menorca.caeb.com/od9c2/xjdmy/brunei.php>brunei</a> <a href=http://menorca.caeb.com/od9c2/xjdmy/doreen.php>doreen</a>

• InputText inside Primefaces dataTable is not refreshed

  - by robson

  I need to have inputTexts inside datatable when form is in editable mode. Everything works properly except form cleaning with immediate="true" (without form validation). Then primefaces datatable behaves unpredictable. After filling in datatable with new data - it still stores old values. Short example: test.xhtml <h:body> <h:form id="form"> <p:dataTable var="v" value="#{test.list}" id="testTable"> <p:column headerText="Test value"> <p:inputText value="#{v}"/> </p:column> </p:dataTable> <h:dataTable var="v" value="#{test.list}" id="testTable1"> <h:column> <f:facet name="header"> <h:outputText value="Test value" /> </f:facet> <p:inputText value="#{v}" /> </h:column> </h:dataTable> <p:dataTable var="v" value="#{test.list}" id="testTable2"> <p:column headerText="Test value"> <h:outputText value="#{v}" /> </p:column> </p:dataTable> <p:commandButton value="Clear" actionListener="#{test.clear()}" immediate="true" update=":form:testTable :form:testTable1 :form:testTable2"/> <p:commandButton value="Update" actionListener="#{test.update()}" update=":form:testTable :form:testTable1 :form:testTable2"/> </h:form> </h:body> And java: import java.io.Serializable; import java.util.ArrayList; import java.util.List; import javax.annotation.PostConstruct; import javax.faces.bean.ViewScoped; import javax.inject.Inject; import javax.inject.Named; @Named @ViewScoped public class Test implements Serializable { private static final long serialVersionUID = 1L; private List<String> list; @PostConstruct private void init(){ update(); } public List<String> getList() { return list; } public void setList(List<String> list) { this.list = list; } public void clear() { list = new ArrayList<String>(); } public void update() { list = new ArrayList<String>(); list.add("Item 1"); list.add("Item 2"); } } In the example above I have 3 configurations: 1. p:dataTable with p:inputText 2. h:dataTable with p:inputText 3. p:dataTable with h:outputText And 2 buttons: first clears data, second applies data Workflow: 1. Try to change data in inputTexts in p:dataTable and h:dataTable 2. Clear data of list (arrayList of string) - click "clear" button (imagine that you click cancel on form because you don't want to store data to database) 3. Load new data - click "update" button (imagine that you are openning new form with new data) Question: Why p:dataTable with p:inputText still stores manually changed data, not the loaded ones? Is there any way to force p:dataTable to behaving like h:dataTable in this case?

• RSA encryption/ Decryption in a client server application

  - by user308806

  Hi guys, probably missing something very straight forward on this, but please forgive me, I'm very naive! Have a client server application where the client identifies its self with an RSA encrypted username & password. Unfortunately I'm getting a "bad padding exception: data must start with zero" when i try to decrypt with the public key on the client side. I'm fairly sure the key is correct as I have tested encrypting with public key then decrypting with private key on the client side with no problems at all. Just seems when I transfer it over the connection it messses it up somehow?! Using PrintWriter & BufferedReader on the sockets if thats of importance. EncodeBASE64 & DecodeBASE64 encode byte[] to 64base and vice versa respectively. Any ideas guys?? Client side: Socket connectionToServer = new Socket("127.0.0.1", 7050); InputStream in = connectionToServer.getInputStream(); DataInputStream dis = new DataInputStream(in); int length = dis.readInt(); byte[] data = new byte[length]; // dis.readFully(data); dis.read(data); System.out.println("The received Data*****************************************"); System.out.println("The length of bits "+ length); System.out.println(data); System.out.println("***********************************************************"); Decryption d = new Decryption(); byte [] ttt = d.decrypt(data); System.out.print(data); String ss = new String(ttt); System.out.println("***********************"); System.out.println(ss); System.out.println("************************"); Server Side: in = connectionFromClient.getInputStream(); OutputStream out = connectionFromClient.getOutputStream(); DataOutputStream dataOut = new DataOutputStream(out); LicenseList licenses = new LicenseList(); String ValidIDs = licenses.getAllIDs(); System.out.println(ValidIDs); Encryption enc = new Encryption(); byte[] encrypted = enc.encrypt(ValidIDs); byte[] dd = enc.encrypt(ValidIDs); String tobesent = new String(dd); //byte[] rsult = enc.decrypt(dd); //String tt = String(rsult); System.out.println("The sent data**********************************************"); System.out.println(dd); String temp = new String(dd); System.out.println(temp); System.out.println("*************************************************************"); //BufferedWriter bf = new BufferedWriter(OutputStreamWriter(out)); //dataOut.write(ValidIDs.getBytes().length); dataOut.writeInt(ValidIDs.getBytes().length); dataOut.flush(); dataOut.write(encrypted); dataOut.flush(); System.out.println("********Testing**************"); System.out.println("Here are the ids:::"); System.out.println(licenses.getAllIDs()); System.out.println("**********************"); //bw.write("it is working well\n");

• Application shows low memory warning and crashes while loading images?

  - by Bhoomi

  I am using following code for loading images from server using following code.When i scroll UITableView application crashes. AsynchrohousImageView class .m file - (void)dealloc { [connection cancel]; //in case the URL is still downloading [connection release]; [data release]; [_imageView release]; [_activityIndicator release]; [super dealloc]; } - (void)loadImageFromURL:(NSURL*)url defaultImageName:(NSString *)defaultImageName showDefaultImage:(BOOL)defaultImageIsShown showActivityIndicator:(BOOL)activityIndicatorIsShown activityIndicatorRect:(CGRect)activityIndicatorRect activityIndicatorStyle:(UIActivityIndicatorViewStyle)activityIndicatorStyle { if (connection!=nil) { [connection release]; } if (data!=nil) { [data release]; } if ([[self subviews] count]>0) { [[[self subviews] objectAtIndex:0] removeFromSuperview]; // } if (defaultImageIsShown) { self.imageView = [[[UIImageView alloc] initWithImage:[UIImage imageNamed:defaultImageName]] autorelease]; } else { self.imageView = [[[UIImageView alloc] init] autorelease]; } [self addSubview:_imageView]; _imageView.frame = self.bounds; [_imageView setNeedsLayout]; [self setNeedsLayout]; if (activityIndicatorIsShown) { self.activityIndicator = [[[UIActivityIndicatorView alloc] initWithActivityIndicatorStyle:activityIndicatorStyle] autorelease]; [self addSubview:_activityIndicator]; _activityIndicator.frame = activityIndicatorRect; _activityIndicator.center = CGPointMake(_imageView.frame.size.width/2, _imageView.frame.size.height/2); [_activityIndicator setHidesWhenStopped:YES]; [_activityIndicator startAnimating]; } NSURLRequest* request = [NSURLRequest requestWithURL:url cachePolicy:NSURLRequestUseProtocolCachePolicy timeoutInterval:60.0]; connection = [[NSURLConnection alloc] initWithRequest:request delegate:self]; } - (void)connection:(NSURLConnection *)theConnection didReceiveData:(NSData *)incrementalData { if (data==nil) { data = [[NSMutableData alloc] initWithCapacity:2048]; } [data appendData:incrementalData]; } - (void)connectionDidFinishLoading:(NSURLConnection*)theConnection { [connection release]; connection=nil; _imageView.image = [UIImage imageWithData:data]; if (_activityIndicator) { [_activityIndicator stopAnimating]; } [data release]; data=nil; } - (UIImage*) image { UIImageView* iv = [[self subviews] objectAtIndex:0]; return [iv image]; } In ViewController Class Which loads image - (UITableViewCell *)tableView:(UITableView *)tV cellForRowAtIndexPath:(NSIndexPath *)indexPath { static NSString *reuseIdentifier =@"CellIdentifier"; ListCell *cell = (ListCell *)[tableView dequeueReusableCellWithIdentifier:reuseIdentifier]; if (cell==nil) { cell = [[ListCell alloc]initWithStyle:UITableViewCellStyleDefault reuseIdentifier:reuseIdentifier]; NSMutableDictionary *dicResult = [arrResults objectAtIndex:indexPath.row]; NSURL *url=[NSURL URLWithString:[dicResult objectForKey:@"Image"]]; AsynchronousImageView *asyncImageView = [[AsynchronousImageView alloc] initWithFrame:CGRectMake(5, 10,80,80)]; [asyncImageView loadImageFromURL:url defaultImageName:@"DefaultImage.png" showDefaultImage:NO showActivityIndicator:YES activityIndicatorRect:CGRectMake(5, 10,30,30) activityIndicatorStyle:UIActivityIndicatorViewStyleGray]; // load our image with URL asynchronously [cell.contentView addSubview:asyncImageView]; // cell.imgLocationView.image = [UIImage imageNamed:[dicResult valueForKey:@"Image"]]; [asyncImageView release]; } if([arrResults count]==1) { UITableViewCell *cell1=[tableView dequeueReusableCellWithIdentifier:reuseIdentifier]; if(cell1==nil) cell1=[[[UITableViewCell alloc]initWithStyle:UITableViewCellStyleDefault reuseIdentifier:reuseIdentifier] autorelease]; NSMutableDictionary *dicResult = [arrResults objectAtIndex:0]; cell1.textLabel.text=[dicResult valueForKey:@"NoResults"]; return cell1; } else { NSMutableDictionary *dicResult = [arrResults objectAtIndex:indexPath.row]; NSString *title = [NSString stringWithFormat:@"%@ Bedrooms-%@", [dicResult valueForKey:KEY_NUMBER_OF_BEDROOMS],[dicResult valueForKey:KEY_PROPERTY_TYPE]]; NSString *strAddress = [dicResult valueForKey:KEY_DISPLAY_NAME]; NSString *address = [strAddress stringByReplacingOccurrencesOfString:@", " withString:@"\n"]; NSString *price = [dicResult valueForKey:KEY_PRICE]; NSString *distance = [dicResult valueForKey:KEY_DISTANCE]; cell.accessoryType = UITableViewCellAccessoryDisclosureIndicator; cell.lblTitle.text = title; cell.lblAddress.text = address; if ([price length]>0) { cell.lblPrice.text = [NSString stringWithFormat:@"£%@",price]; }else{ cell.lblPrice.text = @""; } if ([distance length]>0) { cell.lblmiles.text = [NSString stringWithFormat:@"%.2f miles",[distance floatValue]]; }else{ cell.lblmiles.text = @""; } } return cell; } How can i resolve this? I have attached heapshot analysis screen shot of it.Here non Object consumes so much of memory what is that?

• Inheriting XML files and modifying values

  - by Veehmot

  This is a question about concept. I have an XML file, let's call it base: <base id="default"> <tags> <tag>tag_one</tag> <tag>tag_two</tag> <tag>tag_three</tag> </tags> <data> <data_a>blue</data_a> <data_b>3</data_b> </data> </base> What I want to do is to be able to extend this XML in another file, modifying individual properties. For example, I want to inherit that file and make a new one with a different data/data_a node: <base id="green" import="default"> <data> <data_a>green</data_a> </data> </base> So far it's pretty simple, it replaces the old data/data_a with the new one. I even can add a new node: <base id="ext" import="default"> <moredata> <data>extended version</data> </moredata> </base> And still it's pretty simple. The problem comes when I want to delete a node or deal with XML Lists (like the tags node). How should I reference a particular index on a list? I was thinking doing something like: <base id="diffList" import="default"> <tags> <tag index="1">this is not anymore tag_two</tag> </tags> </base> And for deleting a node / array index: <base id="deleting" import="default"> <tags> <tag index="2"/> </tags> <data/> </base> <!-- This will result in an XML containing these values: --> <base> <tag>tag_one</tag> <tag>tag_two</tag> </base> But I'm not happy with my solutions. I don't know anything about XSLT or other XML transformation tools, but I think someone must have done this before. The key goal I'm looking for is ease to write the XML by hand (both the base and the "extended"). I'm open to new solutions besides XML, if they are easy to write manually. Thanks for reading.

• How to implement this .NET client and PHP server synchronization scenario?

  - by pbean

  I have a PHP webserver and a .NET mobile application. The .NET application needs data from a database, which is provided (for now) by the php webserver. I'm fairly new to this kind of scenario so I'm not sure what the best practices are. I ran into a couple of problems and I am not certain how to overcome them. For now, I have the following setup. I run a PHP SOAP server which has a couple of operations which simply retrieve data from the database. For this web service I have created a WSDL file. In Visual Studio I added a web reference to my project using the WSDL file and it generated some classes for it. I simply call something like "MyWebService.GetItems();" and I get an array of items in my .NET application, which come straight from the database. Next I also serialize all these retrieved objects to local (permanent) storage. I face a couple of challenges which I don't know how to resolve properly. The idea is for the mobile client to synchronize the data once (at the start of the day), before working, and then use the local storage throughout the day, and synchronize it back at the end of the day. At the moment all data is downloaded through SOAP, and not a subset (only what is needed). How would I know which new information should be sent to the client? Only the server knows what is new, but only the client knows for sure which data it already has. I seem to be doing double work now. The data which is transferred with SOAP basically already are serialized objects. But at the moment I first retrieve all objects through SOAP and the .NET framework automatically deserializes it. Then I serialize all data again myself. It would be more efficient to simply download it to storage, and then deserialize it. The mobile device does not have a lot of memory. In my test data this is not really a problem, but with potentially tenths of thousands of records I can imagine this will become a problem. Currently when I call the SOAP method, it loads all data into memory (as an array) but as described above perhaps it would be better to have it stored into storage directly, and only retrieve from storage the objects that are needed. But how would I store this? An array would serialize to one big XML (or binary) file from which I cannot choose which objects to load. Would I make (possible tenths of thousands) separate files? Also at the end of the day when I want to send the changes back to the server, how would I know which objects to send... since they're not in memory? I hope my troubles are clear and I hope you are able to help me figure out how to implement this the best way. :) Some things are already fixed (like using .NET on the mobile device, using PHP and having a MySQL database server) but other things can most certainly be changed (like using SOAP).
