• Galaxy Nexus (Specificaly) camera startPreview failed

  I'm having a strange issue on a galaxy nexus when trying to have a live camera view in my app. I get this error in the log cat: 06-29 16:31:26.681 I/CameraClient(133): Opening camera 0 06-29 16:31:26.681 I/CameraHAL(133): camera_device open 06-29 16:31:26.970 D/DOMX (133): ERROR: failed check:(eError == OMX_ErrorNone) || (eError == OMX_ErrorNoMore) - returning error: 0x80001005 - Error returned from OMX API in ducati 06-29 16:31:26.970 E/CameraHAL(133): Error while configuring rotation 0x80001005 06-29 16:31:27.088 I/am_on_resume_called(21274): [0,digifynotes.Activity_Camera] 06-29 16:31:27.111 V/PhoneStatusBar(693): setLightsOn(true) 06-29 16:31:27.205 E/CameraHAL(133): OMX component is not in loaded state 06-29 16:31:27.205 E/CameraHAL(133): setNSF() failed -22 06-29 16:31:27.205 E/CameraHAL(133): Error: CAMERA_QUERY_RESOLUTION_PREVIEW -22 06-29 16:31:27.252 I/MonoDroid(21274): UNHANDLED EXCEPTION: Java.Lang.Exception: Exception of type 'Java.Lang.Exception' was thrown. 06-29 16:31:27.252 I/MonoDroid(21274): at Android.Runtime.JNIEnv.CallVoidMethod (intptr,intptr) <0x00068> 06-29 16:31:27.252 I/MonoDroid(21274): at Android.Hardware.Camera.StartPreview () <0x0007f> 06-29 16:31:27.252 I/MonoDroid(21274): at DigifyNotes.CameraPreviewView.SurfaceChanged (Android.Views.ISurfaceHolder,Android.Graphics.Format,int,int) <0x000d7> 06-29 16:31:27.252 I/MonoDroid(21274): at Android.Views.ISurfaceHolderCallbackInvoker.n_SurfaceChanged_Landroid_view_SurfaceHolder_III (intptr,intptr,intptr,int,int,int) <0x0008b> 06-29 16:31:27.252 I/MonoDroid(21274): at (wrapper dynamic-method) object.4c65d912-497c-4a67-9046-4b33a55403df (intptr,intptr,intptr,int,int,int) <0x0006b> That very same source code works flawlessly on a Samsung Galaxy Ace 2X (4.0.4) and an LG G2X (2.3.7).

• Javascript: prototypeal inheritance and the prototype proprity

  - by JanD

  Hi, I have a simple code fragment in JS working with prototype inheritance. function object(o) { function F() {} F.prototype = o; return new F(); } //the following code block has a alternate version var mammal={ color: "brown", getColor: function(){ return this.color; } } var myCat = object(mammal); myCat.meow = function(){return "meow";} that worked fine but adding this: mammal.prototype.kindOf = "predator"; does not. ("mammal.prototype is undefined") Since I guessed that object maybe have no prototype I rewrote it, replacing the var mammal={... block with: function mammal(){ this.color="brown"; this.getColor = function(){return this.color;} } which gave me a bunch of other errors: "Function.prototype.toString called on incompatible object" and if I try to call _myCat.getColor() "myCat.getColor is not a function" Now I am totally confused. After reading Crockford, and Flanagan I did not get the solution for the errors. So it would be great if somebody knows... - why is the prototype undefined in the first example (which is foremost concern; I thought the prototype of explicitly set in the object() function) - why get I these strange errors trying to use the mammal function as prototype object in the object() function?

• Problem with Silverlight 3 projects in Web Developer Express 2008

  - by MNT

  Hi, I have a strange problem when working with silverlight 3 projects in Web Developer Express 2008. Mainly, I cannot show the design view of a XAML file. Also the XAML files (markup) are shown as plain text files (No Syntax coloring & No Intellisense). However I can write an application that is compiled and run successfully. I have the following installed on my machine: Windows XP SP3 Visual Web Developer Express 2008 SP1 & .NET 3.5 SP1 SL3 Requirements I had a few problems while installing SL3 SDK & Tool for VS. I repeated the process many times until the installation succeeded. The main problem was in the "SL Tools for VS" installation where I used to get an error in the middle. My workaround was to extract the MSI file and manually run the VWDxxx installer from the extracted files. Is this the cause of the problem? Kindly advise as it's impractical to work w/o Intellisense. Thnak you

• Make browser to go back by reloading page 1st and then scrolling it back again too

  - by Marco Demaio

  EXPLAINING WHAT I'M TRYING TO SOLVE: I have a webpage (file_list.php) showing a list of files, and next to each file there is a button to delete it. When user press the DELETE button close to a certain file name, the browser goes to a script called delete_file.php that deletes the file and then it tells browser to go back to the file_list.php delete_file.php uses a simple header("Location: file_list.php”); to go back to file_list.php When browser goes back to file_list.php it reloads the page, but it DOES NOT scroll it back again to where the user was before. So let's say the user scrolled the files list and deleted the last file, when the browser shows again the page file_list.php it won't be scrolled to the bottom of the page again. THE WORKAROUND I CAME OUT WITH: I found a strange way to work around this, basically instead of using header("Location: file_list.php”); in delete_file.php I simply use a javascript call window.history.go(-1). This workaround works perfectly when user is in session (simply using PHP session_start function): the browser RELOADS the file_list.php page and then scrolls it also bask to where it was before. But if the user is NOT in session the browser scrolls the page but IT DOES NOT RELOAD IT before, so the user would still see the file he deleted in the file list. THE QUESTIONS Do you know how to reproduce the behavior of the browser when goes back being in session even if we are not in session? Do you know a way out of this, even another way of solving this matter? Thanks! *I know I could use AJAX to delete the file so I would not have to go every time to delete_file.php, but this is not the answer*.

• Replacing unversioned files in WiX major upgrade.

  - by Joshua

  I am still having this problem. This is the closest I have come to a solution that works, and yet it doesn't quite work. Here is (most of) the code: <Product Id='$(var.ProductCode)' UpgradeCode='$(var.UpgradeCode)' Name="Pathways" Version='$(var.ProductVersion)' Manufacturer='$(var.Manufacturer)' Language='1033'> Maximum="$(var.ProductVersion)" IncludeMaximum="no" Language="1033" Property="OLDAPPFOUND" / -- -- -- There is a later version of this program installed. The problem I am having is that I need the two files in the Database component to replace the previous copies. Since these files are unversioned, I have attempted to use the CompanionFile tag set to the PathwaysExe since that is the main executable of the application, and it IS being updated, even if the log says it isn't! The strangest thing about this is that the PathwaysLdf file IS BEING UPDATED CORRECTLY, and the PathwaysMdf file IS NOT. The log seems to indicate that the "Existing file is of an equal version (Checked using version of companion)". This is very strange because that file is being replaced just fine. The only idea I have left is that this problem has to do with the install sequence, and I'm not sure how to proceed! I have the InstallExecuteSequence set like I do because of the SettingsXml file, and my need to NOT overwrite that file, which is actually working now, so whatever solution works for the database files can't break the working settings file! ;) The full log is located at: http://pastebin.com/HFiGKuKN PLEASE AND THANK YOU!

• What programming hack from your past are you most ashamed of?

  - by LeopardSkinPillBoxHat

  We've all been there (usually when we are young and inexperienced). Fixing it properly is too difficult, too risky or too time-consuming. So you go down the hack path. Which hack from your past are you most ashamed of, and why? I'm talking about the ones where you would be really embarrassed if someone could attribute the hack to you (quite easily if you are using revision control software). One hack per answer please. Mine was shortly after I started in my first job. I was working on a legacy C system, and there was this strange defect where a screen view failed to update properly under certain circumstances. I wasn't familiar with how to use the debugger at this time, so I added traces into the code to figure out what was going on. Then I realised that the defect didn't occur anymore with the traces in the code. I slowly backed out the traces one-by-one, until I realised that only a single trace was required to make the problem go away. My logic now would tell me that I was dealing with some sort of race-condition or timing related issue that the trace just "hid under the rug". But I checked in the code with the following line, and all was well: printf(""); Which hacks are you ashamed of?

• Problem: Vectorizing Code with Intel Visual FORTRAN for X64

  - by user313209

  I'm compiling my fortran90 code using Intel Visual FORTRAN on Windows Server 2003 Enterprise X64 Edition. When I compile the code for 32 bit structure and using automatic and manual vectorizing options. The code will be compiled, vectorized. And when I run it on 8 core system the compiled code uses 70% of CPU that shows me that vectorizing is working. But when I compile the code with 64 Bit compiler, it says that the code is vectorized but when I run it it only shows CPU usage of about 12% that is full usage for one core out of 8, so it means that while the compiler says that code is vectorized, vectorization is not working. And it's strange for me because it's on a X64 Edition Windows and I was expecting to see the reverse result. I thought that it should be better to run a code that is compiled for 64 Bit architecture on a 64 bit windows. Anyone have any idea why the compiled code is not able to use the full power of multiple cores for 64 Bit Compiled version? Thanks in advance for your responses.

• How can I load txt file from internet into my jsf app?

  - by Elena

  Hi all! It's me again) I have another problem. I want to load file (for example - txt) from web. I tried to use the next code in my managed bean: public void run() { try { URL url = new URL(this.filename); URLConnection connection = url.openConnection(); bufferedReader = new BufferedReader(new InputStreamReader(connection.getInputStream())); if (bufferedReader == null) { return; } System.out.println("wwwwwwwwwwwwwwwwwwwww"); String str = bufferedReader.readLine(); System.out.println("qqqqqqqqqqqqqqqqqqqqqqq = " + str); while (bufferedReader.readLine() != null) { System.out.println("---- " + bufferedReader.readLine()); } } catch(MalformedURLException mue) { System.out.println("MalformedURLException in run() method"); mue.printStackTrace(); } catch(IOException ioe) { System.out.println("IOException in run() method"); ioe.printStackTrace(); } finally { try { bufferedReader.close(); } catch(IOException ioe) { System.out.println("UOException wile closing BufferedReader"); ioe.printStackTrace(); } } } public String doFileUpdate() { String str = FacesContext.getCurrentInstance().getExternalContext().getRequestServletPath(); System.out.println("111111111111111111111 str = " + str); str = "http://narod.ru/disk/20957166000/test.txt.html";//"http://localhost:8080/sfront/files/test.html"; System.out.println("222222222222222222222 str = " + str); FileUpdater fileUpdater = new FileUpdater(str); fileUpdater.run(); return null; } But the BufferedReader returns the html code of the current page, where i am trying to call managed bean's method. It's very strange thing - I have googled and none have had this problem. Maybe I do something wrong, maybe there us a simplest way to load file into web (jsf) app not using net API. Any ideas? Thanks very much for help! With best wishes)

• Making one table equal to another without a delete *

  - by Joshua Atkins

  Hey, I know this is bit of a strange one but if anyone had any help that would be greatly appreciated. The scenario is that we have a production database at a remote site and a developer database in our local office. Developers make changes directly to the developer db and as part of the deployment process a C# application runs and produces a series of .sql scripts that we can execute on the remote side (essentially delete *, insert) but we are looking for something a bit more elaborate as the downtime from the delete * is unacceptable. This is all reference data that controls menu items, functionality etc of a major website. I have a sproc that essentially returns a diff of two tables. My thinking is that I can insert all the expected data in to a tmp table, execute the diff, and drop anything from the destination table that is not in the source and then upsert everything else. The question is that is there an easy way to do this without using a cursor? To illustrate the sproc returns a recordset structured like this: TableName Col1 Col2 Col3 Dest Src Anything in the recordset with TableName = Dest should be deleted (as it does not exist in src) and anything in Src should be upserted in to dest. I cannot think of a way to do this purely set based but my DB-fu is weak. Any help would be appreciated. Apologies if the explanation is sketchy; let me know if you need anymore details.

• Cocoa/Objective-C - Child window with text input without main window becoming inactive

  - by Josh

  Hello All, I have a need to spawn a window that will hover just above my main window in a cocoa application. I want this main window to allow the user to enter some text in an input box. All is well until the text input box actually gains focus. The main window becomes "deactivated." This window is borderless and is a slightly custom shape -- its more like a hover card than anything else, I suppose. Basically, I'd like this thing to work almost exactly like Spotlight (Apple + Space) -- you can enter text, but this is such an an ancillary operation that in the context of the greater UX, you don't want the jarring effect of the main window graying out (becoming inactive). You'll notice when you have some application open and in-focus, spotlight will not cause the window of that application to become inactive. This problem arises because text input seems to REQUIRE that the child window become the key window (it will not let you place the cursor in the text input field). When it becomes key, the main window becomes inactive. So far I've tried: Subclassing NSWindow for my main application and overriding isKeyWindow such that it only loses key when the application is no longer the users focus (as opposed to the window). This had the unintended effect of colliding with key status of the child window and having very strange effects on the keyboard input (some keys are not captured, like delete) Creating a view instead of a window. Doesn't work because of this problem -- you cannot draw over a Webkit WebView these days. Anybody Cocoa/OSX wizards have any ideas? I've become a little obsessed with this one. An itch I can't scratch.

• Javascript: prototypal inheritance and the prototype property

  - by JanD

  Hi, I have a simple code fragment in JS working with prototype inheritance. function object(o) { function F() {} F.prototype = o; return new F(); } //the following code block has a alternate version var mammal = { color: "brown", getColor: function() { return this.color; } } var myCat = object(mammal); myCat.meow = function(){return "meow";} that worked fine but adding this: mammal.prototype.kindOf = "predator"; does not.

Edit by the Creator of the Question: These two links helped a lot too: Prototypes_in_JavaScript on the spheredev wiki explains the way the prototype property works relativily simple. What it lacks is some try-out code examples. Some good examples are provided by Morris John's Article. I personally find the explanations are not that easy as in the first link, but still very good. The most difficult part even after I actually got it is really not to confuse the .prototype propery with the internal [[Prototype]] of an object.

• git pull crashes after other member push something

  - by naiad

  Here it's the story... we have a Github account. I clone the repository ... then I can work with it, commit things, push things, etc ... I use Linux with command line and git version 1.7.7.3 Then other user, using Eclipse and git plugin for eclipse eGit 1.1.0 pushes something, and it appears in the github web pages as the last commit, but when I try to pull: $ git pull remote: Counting objects: 13, done. remote: Compressing objects: 100% (6/6), done. remote: Total 9 (delta 2), reused 7 (delta 0) Unpacking objects: 100% (9/9), done. error: unable to find 3e6c5386cab0c605877f296642d5183f582964b6 fatal: object 3e6c5386cab0c605877f296642d5183f582964b6 not found "3e6c5386cab0c605877f296642d5183f582964b6" is the commit hash of the last commit, done by the other user ... there's no problem at all to browse it through web page ... but for me it's impossible to pull it. It's strange, because my command line output tells about that commit hash, so it knows that one is the last one commit in the github system, but my git can not pull it ! Maybe the git protocol used in eGit is incompatible with the console git 1.7.7.3...

• SWT: problems with clicking button after using setEnabled() on Linux

  - by Laimoncijus

  Hi, I have a strange case with SWT and Button after using setEnabled() - seems if I disable and enable button at least once - I cannot properly click with mouse on it anymore... Already minify code to very basic: import org.eclipse.swt.SWT; import org.eclipse.swt.events.SelectionEvent; import org.eclipse.swt.events.SelectionListener; import org.eclipse.swt.layout.GridLayout; import org.eclipse.swt.widgets.Button; import org.eclipse.swt.widgets.Display; import org.eclipse.swt.widgets.Shell; public class TestButton { public TestButton() { Display display = new Display(); Shell shell = new Shell(display); GridLayout mainLayout = new GridLayout(); shell.setLayout(mainLayout); shell.setSize(100, 100); Button testButton = new Button(shell, SWT.PUSH); testButton.addSelectionListener(new TestClickListener()); testButton.setText("Click me!"); //testButton.setEnabled(false); //testButton.setEnabled(true); shell.open(); while (!shell.isDisposed()) { if (!display.readAndDispatch()) display.sleep(); } display.dispose(); } class TestClickListener implements SelectionListener { @Override public void widgetDefaultSelected(SelectionEvent e) { } @Override public void widgetSelected(SelectionEvent e) { System.out.println("Click!"); } } public static void main(String[] args) { new TestButton(); } } When I keep these 2 lines commented out - I can properly click on a button and always get "Click!" logged, but if I uncomment them - then I can't click on button properly with mouse anymore - button visually seems to be clicked, but nothing is logged... Am I doing something wrong here? Or maybe it's some kind of bug on Linux platform? Because on Mac running the same code I never experienced such problems... Thanks for any hint! P.S. Running code on Ubuntu 9.10, Gnome + Compiz, Sun Java 1.6.0.16

• Does mod_php honor HEAD requests properly?

  - by rkulla

  The HTTP/1.1 RFC stipulates "The HEAD method is identical to GET except that the server MUST NOT return a message-body in the response." I know Apache honors the RFC but modules don't have to. My question is, does mod_php5 honor this? The reason I ask is because I just came across an article saying that PHP developers should check this themselves with: if (stripos($_SERVER['REQUEST_METHOD'], 'HEAD') !== FALSE) { exit(); } but seeing as how browsers send HEAD requests for cache checking it seems unlikely to me that no book, docs, etc., advise PHP developers to do this check. I googled a second and not much turned up, other than some people saying they try to strange things like mod_rewrite/redirect after getting HEAD requests and some old bug ticket from like 2002 claiming that mod_php still executed the rest of the script by default. So I just ran a quick test by using PECL::HTTP to run http_head('http://mysite.com/test-head-request.php'); while having: <?php error_log('REST OF SCRIPT STILL RAN'); ?> in test-head-request.php to see if the rest of the script still executed, and it didn't. I figure that should be enough to settle it, but want to get more feedback and maybe help clear up confusion for anyone else who has wondered about this. So if anyone knows off the top of their head (no pun intended) - or have any conventions they use for receiving HEAD requests, that'd be great. Otherwise, I'll grep the C source later and respond in a comment with my findings. Thanks.

• How to push this view controller ?

  - by hib

  Hello all, I am caught in a strange requirement .See the following view hierarchy and scenario . I have a tab bar application in which I have three tabs . In first tab I am showing some content with a small image title and date (uitableview in navigation controller). In the detail view of that controller there are more buttons that shows different sorts of detail like gallery button and , more details button and some , more button . On tapping each button I will push each individual view controller in the main navigation controller . Now on the horizontal orientation I am showing same list of content but in the cover flow ( in modal view controller ) fashion like the ipod application . On tapping any image we will show the same buttons like gallery and more details and tapping on it will show the new controller with the following code : UINavigationController *modalNavController = [[UINavigationController alloc] initWithRootViewController:myPhotoController]; UIBarButtonItem *backButton = [[UIBarButtonItem alloc] initWithTitle:@"Back" style:UIBarButtonItemStyleBordered target:self action:@selector(backButtonPressed)]; myPhotoController.navigationItem.leftBarButtonItem = backButton; [backButton release]; if([self.modalViewController isViewLoaded]){ [self dismissModalViewControllerAnimated:YES]; } modalNavController.navigationBar.barStyle = UIBarStyleBlackOpaque; [self presentModalViewController:modalNavController animated:YES]; [modalNavController release]; All this is working nicely . but when I get back the device in vertical orientation . the main modal controller will be dismissed and all the containing modal controller also will be dismissed if they are open or not . Instead of this what I want is If chooses an item in the coverflow and then if chooses gallery and if I put the device in vertical orientaion the gallery should be in the navigation hierarchy that drove me to the main list and gallery should be in horizonatal fashion . So what I want to do is that just to push the gallery controller in the main navigation hierarchy instead of showing from a madal controller . If someone wants reference then see the application "net a porter" I want to do like that . Just tell me how the controller hierarchy is working in that app . I need the help . Thanks

• nhibernate not taking mappings from assembly

  Hi I'm using fnh and castle nhib facility. I followed the advice from mike hadlow here: http://mikehadlow.blogspot.com/2009/01/integrating-fluent-nhibernate-and.html here is my FluentNHibernateConfigurationBuilder: public Configuration GetConfiguration(IConfiguration facilityConfiguration) { var defaultConfigurationBuilder = new DefaultConfigurationBuilder(); var configuration = defaultConfigurationBuilder.GetConfiguration(facilityConfiguration); configuration.AddMappingsFromAssembly(typeof(User).Assembly); return configuration; } i know the facility is picking it up as i can break inside that method and it steps through. however, when it's done, non of the mappings are created and i get the following error when i try to save an entity: No persister for: IsItGd.Model.Entities.User here is my user class: //simple model of web user public class User { public virtual int Id { get; set; } public virtual string FullName { get; set; } } and here is the mapping: public class UserMap : ClassMap<User> { public UserMap() { Id(x=>x.Id); Map(x=>x.FullName); } } i really can't see what the problem is. the strange thing is - is that if i use automapping it picks everything up - but i don't want to use automapping as i can't do certain things in that scenario. any clues? w://

• stack overflow problem in program

  - by Jay

  So I am currently getting a strange stack overflow exception when i try to run this program, which reads numbers from a list in a data/text file and inserts it into a binary search tree. The weird thing is that when the program works when I have a list of 4095 numbers in random order. However when i have a list of 4095 numbers in increasing order (so it makes a linear search tree), it throws a stack overflow message. The problem is not the static count variable because even when i removed it, and put t=new BinaryNode(x,1) it still gave a stack overflow exception. I tried debugging it, and it broke at if (t == NULL){ t = new BinaryNode(x,count); Here is the insert function. BinaryNode *BinarySearchTree::insert(int x, BinaryNode *t) { static long count=0; count++; if (t == NULL){ t = new BinaryNode(x,count); count=0; } else if (x < t->key){ t->left = insert(x, t->left); } else if (x > t->key){ t->right = insert(x, t->right); } else throw DuplicateItem(); return t; }

• Ruby - encrypted_strings

  - by Tom Andersen

  A bit of a Ruby newbie here - should be an easy question: I want to use the encrypted_strings gem to create a password encrypted string: (from http://rdoc.info/projects/pluginaweek/encrypted_strings) Question is: Everything works fine, but how come I don't need the password to decrypt the string? Say I want to store the string somewhere for a while,like the session. Is the password also stored with it? (which would seem very strange?). And no, I'm not planning on using 'secret-key' or any similar hack as a password. I am planning on dynamically generating a class variable @@password using a uuid, which I don't store other than in memory, and can change from one running of the program to the next. Symmetric: >> password = 'shhhh' => "shhhh" >> crypted_password = password.encrypt(:symmetric, :password => 'secret_key') => "qSg8vOo6QfU=\n" >> crypted_password.class => String >> crypted_password == 'shhhh' => true >> password = crypted_password.decrypt => "shhhh"

• Flash "visible" issue

  - by justkevin

  I'm writing a tool in Flex that lets me design composite sprites using layered bitmaps and then "bake" them into a low overhead single bitmapData. I've discovered a strange behavior I can't explain: toggling the "visible" property of my layers works twice for each layer (i.e., I can turn it off, then on again) and then never again for that layer-- the layer stays visible from that point on. If I override "set visible" on the layer as such: override public function set visible(value:Boolean):void { if(value == false) this.alpha = 0; else {this.alpha = 1;} } The problem goes away and I can toggle "visibility" as much as I want. Any ideas what might be causing this? Edit: Here is the code that makes the call: private function onVisibleChange():void { _layer.visible = layerVisible.selected; changed(); } The changed() method "bakes" the bitmap: public function getBaked():BitmapData { var w:int = _composite.width + (_atmosphereOuterBlur * 2); var h:int = _composite.height + (_atmosphereOuterBlur * 2); var bmpData:BitmapData = new BitmapData(w,h,true,0x00000000); var matrix:Matrix = new Matrix(); var bounds:Rectangle = this.getBounds(this); matrix.translate(w/2,h/2); bmpData.draw(this,matrix,null,null,new Rectangle(0,0,w,h),true); return bmpData; } Incidentally, while the layer is still visible, using the Flex debugger I can verify that the layer's visible value is "false".

• Moral fits the story or suggest me a nice moral?

  - by Gobi

  A 25 year old son was sitting beside his old father in a train one day. When the train was about to leave, all the passengers started settling down in their seats. The son was filled with joy and anxiety. He was seated by the window. He put his hand out and felt the breeze and screamed, “ Papa look at all the trees, they are moving behind”. The old father smiled and admired his son’s feelings. Beside the old man, a couple was also travelling and observed this strange behavior. They found something awkward and childish in the behavior of this 25 year old man. All of a sudden, the son shouted again “Papa see! The clouds are moving about; there is a pond down and many cows are drinking it’s water”. It soon started drizzling. Once again, the young man felt exited and said “papa, I can see and feel the rain drops touching my hand”. The couple seeing this and feeling concerned, asked the old man “why don’t you consult a good doctor and treat your son; don’t you find something abnormally different in him ?” The old man replied, “Yes, I have provided the best treatment for my only boy. We are just returning from the hospital. I am happy for today is the day he has received his sense of sight. It’s for the first time my son is seeing and relishing these little wonders which we have been watching and ignoring in our routine life!” The couple had no words to reply and felt sorry for their remarks. Moral of the story: “ “don’t judge a book by its cover”. is this the moral fits the story or provide me some moral for this story :)

• Save has_and_belongs_to_many link in basic RoR app

  - by Stéphane V

  I try to learn the has_and_belongs_to_many relationship between my 2 fresh new and simple models Product and Author, where a Product can have many authors and where author can have a lots of products. I wrote this : class Author < ActiveRecord::Base has_and_belongs_to_many :products end class Product < ActiveRecord::Base has_and_belongs_to_many :authors end In the partial form of view for the products, I have : <p>Products</p> <%= collection_select(:product, :author_ids, @authors, :id, :name, :prompt => " ", :multiple => true) %> but when I hit the update button, I get this strange message I can't resolve myself : NoMethodError in ProductsController#update undefined method `reject' for "1":String Rails.root: /home/stephane/www/HABTM Application Trace | Framework Trace | Full Trace app/controllers/products_controller.rb:63:in block in update' app/controllers/products_controller.rb:62:inupdate' Request Parameters: {"utf8"="✓", "_method"="put", "authenticity_token"="2GlTssOFjTVZ9BikrIFgx22cdTOIJuAB70liYhhLf+4=", "product"={"title"="Le trésor des Templiers", "original_title"="", "number"="1", "added_by"="", "author_ids"="1"}, "commit"="Update Product", "id"="1"} What's wrong ? Is there a problem with :product_ids... I saw on internet I had to pu a "s" but I'm not sure of what it represents.... How can I link the table authors_products to the key which is given back by the drop-down menu ? (here "author_ids"="1") Thx !

• reading excel using scriptom for groovy, producing xml

  - by john

  Dear friends, I got a program from http://kousenit.wordpress.com/2007/03/27/groovyness-with-excel-and-xml but I got some very strange results: 1) I can still print xml but two records are not readable. 2) I got exception suggesting some thing missing could some experts enlighten me about what might go wrong? I copied the program and result below. thanks! import org.codehaus.groovy.scriptom.ActiveXObject def addresses = new File('addresses1.xls').canonicalPath def xls = new ActiveXObject('Excel.Application') def workbooks = xls.Workbooks def workbook = workbooks.Open(addresses) // select the active sheet def sheet = workbook.ActiveSheet sheet.Visible = true // get the XML builder ready def builder = new groovy.xml.MarkupBuilder() builder.people { for (row in 2..1000) { def ID = sheet.Range("A${row}").Value.value if (!ID) break // use the builder to write out each person person (id: ID) { name { firstName sheet.Range("B${row}").Value.value lastName sheet.Range("C${row}").Value.value } address { street sheet.Range("D${row}").Value.value city sheet.Range("E${row}").Value.value state sheet.Range("F${row}").Value.value zip sheet.Range("G${row}").Value.value } } } } // close the workbook without asking for saving the file workbook.Close(false, null, false) // quits excel xls.Quit() xls.release() however, i got the following results: <people> <person id='1234.0'> <name> <firstName>[C@128a25</firstName> <lastName>[C@5e45</lastName> </name> <address> <street>[C@179ef7c</street> <city>[C@12f95de</city> <state>[C@138b554</state> <zip>12345.0</zip> </address> </person> </person> Exception thrown May 12, 2010 4:07:15 AM org.codehaus.groovy.runtime.StackTraceUtils sanitize WARNING: Sanitizing stacktrace: java.lang.NullPointerException at org.codehaus.groovy.runtime.callsite.GetEffectivePojoFieldSite.acceptGetProperty(GetEffectivePojoFieldSite.java:43) at org.codehaus.groovy.runtime.callsite.AbstractCallSite.callGetProperty(AbstractCallSite.java:237) at sriptom4_excel$_run_closure1.doCall(sriptom4_excel.groovy:18) at sun.reflect.NativeMethodAccessorImpl.invoke0(Native Method) [1]: http://kousenit.wordpress.com/2007/03/27/groovyness-with-excel-and-xml/

• Delphi Shell IExtractIcon usage and result

  - by Roy M Klever

  What I do: Try to extract thumbnail using IExtractImage if that fail I try to extract icons using IExtractIcon, to get maximum iconsize, but IExtractIcon gives strange results. Problem is I tried to use a methode that extracts icons from an imagelist but if there is no large icon (256x256) it will render the smaller icon at the topleft position of the icon and that does not look good. That is why I am trying to use the IExtractIcon instead. But icons that show up as 256x256 icons in my imagelist extraction methode reports icon sizes as 33 large and 16 small. So how do I check if a large (256x256) icon exists? If you need more info I can provide som sample code. if PThumb.Image = nil then begin OleCheck(ShellFolder.ParseDisplayName(0, nil, StringToOleStr(PThumb.Name), Eaten, PIDL, Atribute)); ShellFolder.GetUIObjectOf(0, 1, PIDL, IExtractIcon, nil, XtractIcon); CoTaskMemFree(PIDL); bool:= False; if Assigned(XtractIcon) then begin GetLocationRes := XtractIcon.GetIconLocation(GIL_FORSHELL, @Buf, sizeof(Buf), IIdx, IFlags); if (GetLocationRes = NOERROR) or (GetLocationRes = E_PENDING) then begin Bmp := TBitmap.Create; try OleCheck(XtractIcon.Extract(@Buf, IIdx, LIcon, SIcon, 32 + (16 shl 16))); Done:= False; Roy M Klever

• iPhone developer cert not associating with Provisioning Profiles

  - by baudot

  I'm seeing the dreaded "Code Sign error: The identity 'iPhone Developer' doesn't match any valid certificate/private key pair in the default keychain" error. Strange, as it used to work. Not sure what changed. A few of the symptoms I've noticed beyond this: In the project info, for Code Signing Identity, instead of saying "iPhone Developer: My Name Here", it only says "iPhone Developer", followed by a list of grayed out Provisioning Profiles with the error message "profile doesn't match any valid certificate/private key pair in the keychain." In the organizer, if I click the "Developer Profile" sidebar entry, it shows one entry in the "Identities" pane, "iPhone Distribution: My Name Here". However, no profiles show in the Provisioning Profiles pane. In the organizer, if I click the "Provisioning Profiles" sidebar entry, for each of the profiles there it reports "A valid signing identity matching this profile could not be found in your keychain." I've tried a handful of the usual folk cures for this ailment, without success so far, such as: Cleared my old keypairs and expired developer identity cert out of the keychain. Deleted my old developer profile, created a new one, and regenerated the provisioning profile after. Reconfirmed: The App ID on the provisioning portal for this app is a pure wildcard ID. (The "Bundle Identifier" in the info.plist is just the appname, no reversed domain prefix.) Restored my iPhone. Overstalled the latest version of Xcode.

• Lucene and Special Characters

  - by Brandon

  I am using Lucene.Net 2.0 to index some fields from a database table. One of the fields is a 'Name' field which allows special characters. When I perform a search, it does not find my document that contains a term with special characters. I index my field as such: Directory DALDirectory = FSDirectory.GetDirectory(@"C:\Indexes\Name", false); Analyzer analyzer = new StandardAnalyzer(); IndexWriter indexWriter = new IndexWriter(DALDirectory, analyzer, true, IndexWriter.MaxFieldLength.UNLIMITED); Document doc = new Document(); doc.Add(new Field("Name", "Test (Test)", Field.Store.YES, Field.Index.TOKENIZED)); indexWriter.AddDocument(doc); indexWriter.Optimize(); indexWriter.Close(); And I search doing the following: value = value.Trim().ToLower(); value = QueryParser.Escape(value); Query searchQuery = new TermQuery(new Term(field, value)); Searcher searcher = new IndexSearcher(DALDirectory); TopDocCollector collector = new TopDocCollector(searcher.MaxDoc()); searcher.Search(searchQuery, collector); ScoreDoc[] hits = collector.TopDocs().scoreDocs; If I perform a search for field as 'Name' and value as 'Test', it finds the document. If I perform the same search as 'Name' and value as 'Test (Test)', then it does not find the document. Even more strange, if I remove the QueryParser.Escape line do a search for a GUID (which, of course, contains hyphens) it finds documents where the GUID value matches, but performing the same search with the value as 'Test (Test)' still yields no results. I am unsure what I am doing wrong. I am using the QueryParser.Escape method to escape the special characters and am storing the field and searching by the Lucene.Net's examples. Any thoughts?
