  • What fails in this row level trigger?

    - by newba
    I have this trigger: create or replace trigger t_calctotal after insert or update on item_fornecimento REFERENCING NEW AS NEW OLD AS OLD for each row begin if inserting then dbms_output.put_line(' On Insert'); update fornecimento f set f.total_enc_fornec = f.total_enc_fornec +:NEW.prec_total_if where f.id_fornecimento = :NEW.id_fornecimento; else dbms_output.put_line(' On Update'); update fornecimento f set f.total_enc_fornec = f.total_enc_fornec - :OLD.prec_total_if +:NEW.prec_total_if where f.id_fornecimento = :NEW.id_fornecimento; end if; end; Basically I want to refresh the total value of an order (fornecimento), by suming all the items in item_fornecimento; I have to treat this in a different way, case it's an inserting, case it's an updating. The trigger compiles and all and even worked one time, but it was the only one. I've inserted or updated my prec_total_if in item_fornecimento in sqldeveloper, but the order's (fornecimento) total still not change :(. If it's important, my f.total_enc_fornec it's null until it's replaced by a value inserted by this triggers; it prints the output, but it seems to fail updating.

  • how to implement word count bash shell

    - by codemax
    hey guys. I am trying to write my own code for the word count in bash shell. I did usual way. But i wanna use pipe's output to count the word. So for eg the 1st command is cat and i am redirecting to a file called med. Now i have to use to 'dup2' function to count the words in that file. How can i write the code for my wc? This is the code for my shell pgm : void process( char* cmd[], int arg_count ) { pid_t pid; pid = fork(); char path[81]; getcwd(path,81); strcat(path,"/"); strcat(path,cmd[0]); if(pid < 0) { cout << "Fork Failed" << endl; exit(-1); } else if( pid == 0 ) { int fd; fd =open("med", O_RDONLY); dup2(fd ,0); execvp( path, cmd ); } else { wait(NULL); } } And my wordcount is : int main(int argc, char *argv[]) { char ch; int count = 0; ifstream infile(argv[1]); while(!infile.eof()) { infile.get(ch); if(ch == ' ') { count++; } } return 0; } I dont know how to do input redirection i want my code to do this : When i just type wordcount in my shell implementation, I want it to count the words in the med file by default. Thanks in advance

  • How do we greatly optimize our MySQL database (or replace it) when using joins?

    - by jkaz
    Hi there, This is the first time I'm approaching an extremely high-volume situation. This is an ad server based on MySQL. However, the query that is used incorporates a lot of JOINs and is generally just slow. (This is Rails ActiveRecord, btw) sel = Ads.find(:all, :select = '*', :joins = "JOIN campaigns ON ads.campaign_id = campaigns.id JOIN users ON campaigns.user_id = users.id LEFT JOIN countries ON countries.campaign_id = campaigns.id LEFT JOIN keywords ON keywords.campaign_id = campaigns.id", :conditions = [flashstr + "keywords.word = ? AND ads.format = ? AND campaigns.cenabled = 1 AND (countries.country IS NULL OR countries.country = ?) AND ads.enabled = 1 AND campaigns.dailyenabled = 1 AND users.uenabled = 1", kw, format, viewer['country'][0]], :order = order, :limit = limit) My questions: Is there an alternative database like MySQL that has JOIN support, but is much faster? (I know there's Postgre, still evaluating it.) Otherwise, would firing up a MySQL instance, loading a local database into memory and re-loading that every 5 minutes help? Otherwise, is there any way I could switch this entire operation to Redis or Cassandra, and somehow change the JOIN behavior to match the (non-JOIN-able) nature of NoSQL? Thank you!

  • .net mvc pass dictionary data from view to controller

    - by Wei Ma
    A while ago, I was trying to pass a dictionary data from my view to my controller. And I was able to do so after googling on the net(remember it was one of scott hanselman's posts). The solution I had was something like <%for(int index=0; index<Model.Count(); index++){ var property= Model.ElementAt(index);%> <input type="hidden" name="<%="properties["+index+"].Key"%>"/> <input type="hidden" name="<%="properties["+index+"].Value"%>"/> <%}%> public ActionResult Process(IDictionary<string,string> properties) { doSomething(); return View(); } The code worked for awhile and then I did some refactoring and got rid of this chunk of code. Today, I ran into a situation in which I would like to pass a dictionary again. But no matter how hard I try, the properties parameter received by the action was always null. I tried the above code and <%for(int index=0; index<Model.Count(); index++){ var property= Model.ElementAt(index);%> <input type="hidden" name="<%="properties.Keys["+index+"]"%>"/> <input type="hidden" name="<%="properties.Values["+index+"]"%>"/> <%}%> Neither code worked. I googled again but couldn't find the post that helped me before. Can someone point out what I did wrong? thanks a million.

  • Using Moq callbacks correctly according to AAA

    - by Hadi Eskandari
    I've created a unit test that tests interactions on my ViewModel class in a Silverlight application. To be able to do this test, I'm mocking the service interface, injected to the ViewModel. I'm using Moq framework to do the mocking. to be able to verify bounded object in the ViewModel is converted properly, I've used a callback: [Test] public void SaveProposal_Will_Map_Proposal_To_WebService_Parameter() { var vm = CreateNewCampaignViewModel(); var proposal = CreateNewProposal(1, "New Proposal"); Services.Setup(x => x.SaveProposalAsync(It.IsAny<saveProposalParam>())).Callback((saveProposalParam p) => { Assert.That(p.plainProposal, Is.Not.Null); Assert.That(p.plainProposal.POrderItem.orderItemId, Is.EqualTo(1)); Assert.That(p.plainProposal.POrderItem.orderName, Is.EqualTo("New Proposal")); }); proposal.State = ObjectStates.Added; vm.CurrentProposal = proposal; vm.Save(); } It is working fine, but if you've noticed, using this mechanism the Assert and Act part of the unit test have switched their parts (Assert comes before Acting). Is there a better way to do this, while preserving correct AAA order?

  • Asp.Net Cache, modify an object from cache and it changes the cached value

    - by Glen
    Hi, I'm having an issue when using the Asp.Net Cache functionality. I add an object to the Cache then at another time I get that object from the Cache, modify one of it's properties then save the changes to the database. But, the next time I get the object from Cache it contains the changed values. So, when I modify the object it modifies the version which is contained in cache even though I haven't updated it in the Cache specifically. Does anyone know how I can get an object from the Cache which doesn't reference the cached version? i.e. Step 1: Item item = new Item(); item.Title = "Test"; Cache.Insert("Test", item, null, DateTime.Now.AddHours(1), System.Web.Caching.Cache.NoSlidingExpiration); Step 2: Item item = (Item)Cache.Get("test"); item.Title = "Test 1"; Step 3: Item item = (Item)Cache.Get("test"); if(item.Title == "Test 1"){ Response.Write("Object has been changed in the Cache."); } I realise that with the above example it would make sense that any changes to the item get reflected in cache but my situation is a bit more complicated and I definitely don't want this to happen.

  • jQuery performance

    - by jAndy
    Hi Folks, imagine you have to do DOM manipulation like a lot (in my case, it's kind of a dynamic list). Look at this example: var $buffer = $('<ul/>', { 'class': '.custom-example', 'css': { 'position': 'absolute', 'top': '500px' } }); $.each(pages[pindex], function(i, v){ $buffer.append(v); }); $buffer.insertAfter($root); "pages" is an array which holds LI elements as jQuery object. "$root" is an UL element What happens after this code is, both UL's are animated (scrolling) and finally, within the callback of animate this code is executed: $root.detach(); $root = $buffer; $root.css('top', '0px'); $buffer = null; This works very well, the only thing I'm pi**ed off is the performance. I do cache all DOM elements I'm laying a hand on. Without looking too deep into jQuery's source code, is there a chance that my performance issues are located there? Does jQuery use DocumentFragments to append things? If you create a new DOM element with var new = $('<div/>') it is only stored in memory at this point isnt it?

  • OpenGL/Carbon/Cocoa Memory Management Autorelease issue

    - by Stephen Furlani
    Hoooboy, I've got another doozy of a memory problem. I'm creating a Carbon (AGL) Window, in C++ and it's telling me that I'm autorelease-ing it without a pool in place. uh... what? I thought Carbon existed outside of the NSAutoreleasePool... When I call glEnable(GL_TEXTURE_2D) to do some stuff, it gives me a EXC_BAD_ACCESS warning - but if the AGL Window is never getting release'd, then shouldn't it exist? Setting set objc-non-blocking-mode at (gdb) doesn't make the problem go away. So I guess my question is WHAT IS UP WITH CARBON/COCOA/NSAutoreleasePool? And... are there any resources for Objective-C++? Because crap like this keeps happening to me. Thanks, -Stephen --- CODE --- Test Draw Function void Channel::frameDraw( const uint32_t frameID) { eq::Channel::frameDraw( frameID ); getWindow()->makeCurrent(false); glEnable(GL_TEXTURE_2D); // Throws Error Here } Make Current (Equalizer API from Eyescale) void Window::makeCurrent( const bool useCache ) const { if( useCache && getPipe()->isCurrent( this )) return; _osWindow->makeCurrent(); } void AGLWindow::makeCurrent() const { aglSetCurrentContext( _aglContext ); AGLWindowIF::makeCurrent(); if( _aglContext ) { EQ_GL_ERROR( "After aglSetCurrentContext" ); } } _aglContext is a valid memory location (i.e. not NULL) when I step through. -S!

  • C# WinForms. Multiple Forms in separate threads

    - by Calum Murray
    I'm trying to run an ATM Simulation in C# with Windows Forms that can have more than one instance of an ATM machine transacting with a bank account simultaneously. The idea is to use semaphores/locking to block critical code that may lead to race conditions. My question is this: How can I run two Forms simultaneously on separate threads? In particular, how does all of this fit in with the Application.Run() that's already there? Here's my main class: public class Bank { private Account[] ac = new Account[3]; private ATM atm; public Bank() { ac[0] = new Account(300, 1111, 111111); ac[1] = new Account(750, 2222, 222222); ac[2] = new Account(3000, 3333, 333333); Application.Run(new ATM(ac)); } static void Main(string[] args) { new Bank(); } } ...that I want to run two of these forms on separate threads... public partial class ATM : Form { //local reference to the array of accounts private Account[] ac; //this is a reference to the account that is being used private Account activeAccount = null; private static int stepCount = 0; private string buffer = ""; // the ATM constructor takes an array of account objects as a reference public ATM(Account[] ac) { InitializeComponent(); //Sets up Form ATM GUI in ATM.Designer.cs this.ac = ac; } ... I've tried using Thread ATM2 = new Thread(new ThreadStart(/*What goes in here?*/)); But what method do I put in the ThreadStart constructor, since the ATM form is event-driven and there's no one method controlling it? Thanks, Calum

  • When can a == b be false and a.Equals(b) true?

    - by alastairs
    I ran into this situation today. I have an object which I'm testing for equality; the Create() method returns a subclass implementation of MyObject. MyObject a = MyObject.Create(); MyObject b = MyObject.Create(); a == b; // is false a.Equals(b); // is true Note I have also over-ridden Equals() in the subclass implementation, which does a very basic check to see whether or not the passed-in object is null and is of the subclass's type. If both those conditions are met, the objects are deemed to be equal. The other slightly odd thing is that my unit test suite does some tests similar to Assert.AreEqual(MyObject.Create(), MyObject.Create()); // Green bar and the expected result is observed. Therefore I guess that NUnit uses a.Equals(b) under the covers, rather than a == b as I had assumed. Side note: I program in a mixture of .NET and Java, so I might be mixing up my expectations/assumptions here. I thought, however, that a == b worked more consistently in .NET than it did in Java where you often have to use equals() to test equality.

  • User must have accepted TOS - Facebook Graph API error when posting photos to group page

    - by user370309
    Hi all, I've been struggling to upload an image from the user's computer and posted to our group page using the Facebook Graph API. I was able to send a post request to facebook with the image however, I'm getting this error back: ERROR: (#200) User must have accepted TOS. To some extent, I don't believe that I need the user to authorize himself as the photo is being uploaded to our group page. This below, is the code i'm using: if($albumId != null) { $args = array( 'message' = $description ); $args[basename($photoPath)] = '@' . realpath($photoPath); $ch = curl_init(); $url = 'https://graph.facebook.com/'.$albumId.'/photos?'.$token; curl_setopt($ch, CURLOPT_URL, $url); curl_setopt($ch, CURLOPT_HEADER, false); curl_setopt($ch, CURLOPT_RETURNTRANSFER, true); curl_setopt($ch, CURLOPT_POST, true); curl_setopt($ch, CURLOPT_POSTFIELDS, $args); curl_setopt($ch, CURLOPT_SSL_VERIFYHOST, 0); curl_setopt($ch, CURLOPT_SSL_VERIFYPEER, 0); $data = curl_exec($ch); $photoId = json_decode($data, true); if(isset($photoId['error'])) die('ERROR: '.$photoId['error']['message']); $temp = explode('.', sprintf('%f', $photoId['id'])); $photoId = $temp[0]; return $photoId; } Can somebody tell me if I need to request extra permissions from the user or what i'm doing wrong?

  • How do I Unit Test Actions without Mocking that use UpdateModel?

    - by Hellfire
    I have been working my way through Scott Guthrie's excellent post on ASP.NET MVC Beta 1. In it he shows the improvements made to the UpdateModel method and how they improve unit testing. I have recreated a similar project however anytime I run a UnitTest that contains a call to UpdateModel I receive an ArgumentNullException naming the controllerContext parameter. Here's the relevant bits, starting with my model: public class Country { public Int32 ID { get; set; } public String Name { get; set; } public String Iso3166 { get; set; } } The controller action: [AcceptVerbs(HttpVerbs.Post)] public ActionResult Edit(Int32 id, FormCollection form) { using ( ModelBindingDataContext db = new ModelBindingDataContext() ) { Country country = db.Countries.Where(c => c.CountryID == id).SingleOrDefault(); try { UpdateModel(country, form); db.SubmitChanges(); return RedirectToAction("Index"); } catch { return View(country); } } } And finally my unit test that's failing: [TestMethod] public void Edit() { CountryController controller = new CountryController(); FormCollection form = new FormCollection(); form.Add("Name", "Canada"); form.Add("Iso3166", "CA"); var result = controller.Edit(2 /*Canada*/, form) as RedirectToRouteResult; Assert.IsNotNull(result, "Expected to be redirected on successful POST."); Assert.AreEqual("Show", result.RouteName, "Expected to redirect to the View action."); } ArgumentNullException is thrown by the call to UpdateModel with the message "Value cannot be null. Parameter name: controllerContext". I'm assuming that somewhere the UpdateModel requires the System.Web.Mvc.ControllerContext which isn't present during execution of the test. I'm also assuming that I'm doing something wrong somewhere and just need to pointed in the right direction. Help Please!

  • How to display image within cell boundary

    How can I place an image within the cell boundary? I mean without taking the space of other cell? In the code below, random cells were selected to display images. One image in one cell.

The problem is that, the image seems to take other cells as well. ... setPreferredSize(new Dimension(600,600)); final int ROWS = 6; final int COLS = 6; final int IMAGES = 10; setLayout(new GridBagLayout()); GridBagConstraints gc = new GridBagConstraints(); gc.weightx = 1d; gc.weighty = 1d; gc.insets = new Insets(0, 0, 0, 0);//top, left, bottom, and right gc.fill = GridBagConstraints.NONE; JLabel[][] label = new JLabel[ROWS][COLS]; Random rand = new Random(); // fill the panel with labels for (int i=0;i<IMAGES;i++){ ImageIcon icon = createImageIcon("myImage.jpg"); int r, c; do{ //pick random cell which is empty to avoid overlap image in the same cell r = (int)Math.floor(Math.random() * ROWS); c = (int)Math.floor(Math.random() * COLS); } while (label[r][c]!=null); //scale the image int x = rand.nextInt(20)+30; int y = rand.nextInt(20)+30; Image image = icon.getImage().getScaledInstance(x,y, Image.SCALE_SMOOTH); icon.setImage(image); JLabel lbl = new JLabel(icon); gc.gridx = r; gc.gridy = c; add(lbl, gc); //add image to the cell label[r][c] = lbl; }

  • Spring.net is not injecting chained base class properties!

    - by JohnIdol
    I am successfully injecting base class properties with spring.net with just a class that inherits from a base abstract class. Lets say Class MyClass : MyBase, and I am successfully setting a property like this: <object id="myInstantiableClass" type="myAssembly.MyClass myAssenbly" abstract="true"> <property name="MyBaseClassProperty" ref="anotherObjRef"></property> </object> Where MyBaseClassProperty is a property on the base class. Now I have another abstract class between the old base class and the instantiable class, and I am trying to set properties on both the abstract classes. So MyClass : MyNewBaseClass, and MyNewBaseClass : MyBaseClass. I have an additional property on the new base class (MyNewBaseClassProperty) and I am trying to inject it like this: <object id="myInstantiableClass" type="myAssembly.MyClass myAssenbly" abstract="true"> <property name="MyBaseClassProperty" ref="anotherObjRef"></property> <property name="MyNewBaseClassProperty" ref="someOtherObjRef"></property> </object> The property on the old base class is being injected but the one on the new one is not - and I am not getting an error or anything (so I am pretty sure my config is good), that property is just null! Any help appreciated! P.S. I am on asp.net (not MVC) but I don't think it's related.

  • Adding an annotation to a runtime generated method/class using Javassist

    - by Idan K
    I'm using Javassist to generate a class foo, with method bar, but I can't seem to find a way to add an annotation (the annotation itself isn't runtime generated) to the method. The code I tried looks like this: ClassPool pool = ClassPool.getDefault(); // create the class CtClass cc = pool.makeClass("foo"); // create the method CtMethod mthd = CtNewMethod.make("public Integer getInteger() { return null; }", cc); cc.addMethod(mthd); ClassFile ccFile = cc.getClassFile(); ConstPool constpool = ccFile.getConstPool(); // create the annotation AnnotationsAttribute attr = new AnnotationsAttribute(constpool, AnnotationsAttribute.visibleTag); Annotation annot = new Annotation("MyAnnotation", constpool); annot.addMemberValue("value", new IntegerMemberValue(ccFile.getConstPool(), 0)); attr.addAnnotation(annot); ccFile.addAttribute(attr); // generate the class clazz = cc.toClass(); // length is zero java.lang.annotation.Annotation[] annots = clazz.getAnnotations(); And obviously I'm doing something wrong since annots is an empty array. This is how the annotation looks like: @Retention(RetentionPolicy.RUNTIME) @Target(ElementType.METHOD) public @interface MyAnnotation { int value(); }

  • UnicodeDecodeError on attempt to save file through django default filebased backend

    - by Ivan Kuznetsov
    When i attempt to add a file with russian symbols in name to the model instance through default instance.file_field.save method, i get an UnicodeDecodeError (ascii decoding error, not in range (128) from the storage backend (stacktrace ended on os.exist).

  • Broadcasting an intent to a specific component.

    - by Nic Strong
    I have an activity that is starting a background operation in another service. This activity receives various notifications from this service. As part of the intent I use to initiate the background operation I pass extra data with the context of my activity so the background service can broadcast intents back to me (the download service is a good example of this usage). So in the activity I use the following to attach the context: intent.putExtra(Intents.EXTRA_NOTIFICATION_PACKAGE, IntentTestActivity.this.getPackageName()); intent.putExtra(Intents.EXTRA_NOTIFICATION_CLASS, IntentTestActivity.class.getCanonicalName()); intent.putExtra(Intents.EXTRA_NOTIFICATION_EXTRAS, myContext); I register for the notifications in the activity: IntentFilter intentFilter = new IntentFilter(); intentFilter.addAction(Intents.ACTION_NOTIFICATION); intentFilter.addCategory(Intents.CATEGORY_COMPLETION); intentFilter.addCategory(Intents.CATEGORY_PROGRESSS); Intent intent = registerReceiver(receiver, intentFilter); In the background service I send notifications with the following code: void broadcastNotification(String action, String category, String packageName, String className, String extras, int operationResult) { Intent intent = new Intent(action); intent.addCategory(category); intent.setClassName(packageName, className); if (extras != null) { intent.putExtra(Intents.EXTRA_NOTIFICATION_EXTRAS, extras); } intent.putExtra(Intents.EXTRA_OPERATION_RESULT, operationResult); context.sendBroadcast(intent); } My problem is that the above broadcast will never be received. If however I comment out the line intent.setClassName(packageName, className); Then the broadcast is received. Is it a problem with my filter? Do I have to specify intents intended for a specific component? Or cannot I not use such fine grain control over the delivery of broadcasts. Thanks, Nic

  • Masking FLV video in AS3 with PNG alpha channel.

    - by James Roberts
    Hey there, I'm trying to mask an FLV with a PNG alpha channel. I'm using BitmapData (from a PNG) but it's not working. Is there anything I'm missing? Cut up code below: var musclesLoader:Loader = new Loader(); var musclesContainer:Sprite = new Sprite(); var musclesImage:Bitmap = new Bitmap(); var musclesBitmapData:BitmapData; var musclesVideo:Video = new Video(752, 451.2); var connection:NetConnection = new NetConnection(); var stream:NetStream; function loadMuscles():void { musclesLoader.load(new URLRequest('img/muscles.png')); musclesLoader.contentLoaderInfo.addEventListener(Event.COMPLETE, musclesComplete); } function musclesComplete():void { musclesBitmapData = new BitmapData(musclesLoader.content.width, musclesLoader.content.height, true, 0x000000); musclesImage.bitmapData = musclesBitmapData; musclesImage.smoothing = true; musclesContainer.addChild(musclesImage); contentContainer.addChild(musclesContainer); } function loadMusclesVideo():void { connection.connect(null); stream = new NetStream(connection); stream.client = this; musclesVideo.mask = musclesBitmapData; stage.addChild(musclesVideo); musclesVideo.attachNetStream(stream); stream.bufferTime = 1; stream.receiveAudio(true); stream.receiveVideo(true); stream.play("vid/muscles.flv"); } Outside this code I have a function that adds the containers to the stage, etc and places the objects in the appropriate spots. It sort of works - the mask applies, but in a square (the size of the boundaries of musclesBitmapData) rather than with the shape of the alpha channel. Is this the right way to go about this?

  • StorageClientException: The specified message does not exist?

    - by Aaron
    I have a simple video encoding worker role that pulls messages from a queue encodes a video then uploads the video to storage. Everything seems to be working but occasionally when deleting the message after I am done encoding and uploading I get a "StorageClientException: The specified message does not exist." Although the video is processed, I believe the message is reappearing in the queue because it's not being deleted correctly. Is it possible that another instance of the Worker role is processing and deleting the message? Doesn't the GetMessage() prevent other worker roles from picking up the same message? Am I doing something wrong in the setup of my queue? What could be causing this message to not be found on delete? some code... //onStart() queue setup var queueStorage = _storageAccount.CreateCloudQueueClient(); _queue = queueStorage.GetQueueReference(QueueReference); queueStorage.RetryPolicy = RetryPolicies.Retry(5, new TimeSpan(0, 5, 0)); _queue.CreateIfNotExist(); public override void Run() { while (true) { try { var msg = _queue.GetMessage(new TimeSpan(0, 5, 0)); if (msg != null) { EncodeIt(msg); PostIt(msg); _queue.DeleteMessage(msg); } else { Thread.Sleep(WaitTime); } } catch (StorageClientException exception) { BlobTrace.Write(exception.ToString()); Thread.Sleep(WaitTime); } } }
