  • Android: onClick on LinearLayout with TextView and Button

    - by Terry
    I have a Fragment that uses the following XML layout: <?xml version="1.0" encoding="utf-8"?> <LinearLayout xmlns:android="http://schemas.android.com/apk/res/android" android:layout_width="match_parent" android:layout_height="match_parent" android:background="@drawable/card" android:clickable="true" android:onClick="editActions" android:orientation="vertical" > <TextView android:id="@+id/title" style="@style/CardTitle" android:layout_width="wrap_content" android:layout_height="wrap_content" android:duplicateParentState="true" android:text="@string/title_workstation" /> <Button android:id="@+id/factory_button_edit" style="?android:attr/buttonStyleSmall" android:layout_width="wrap_content" android:layout_height="wrap_content" android:duplicateParentState="true" android:text="@string/label_edit" /> </LinearLayout> As you can see, I have an onClick parameter set on LinearLayout. Now on the TextView this one is triggered correctly, and on all empty area. Just on the Button it doesn't invoke the onClick method that I set. Is this normal? What do I have to do so that the onClick method is invoked everywhere on the LinearLayout?

  • C# How to Present Such Question?

    - by ikurtz
    greetings! i have a C# game program that im developing. it uses sound samples and winsock. when i test run the game most of the audio works fine but from time to time if it is multiple samples being played sequentially the application form shakes a little bit and then goes back to its old position. how do i go about debugging this or present it to you folks in a manageable manner? im sure no one is going to want the whole app code in fear of virus attacks. please guide me.. thanking you. EDIT: i have not been able to pin down any code section that produces this result. it just does and i cannot explain it. EDIT: no the x/y position are not changing. the window like shakes around a few pixels and then goes back to the position were it was before the shake.

  • AVAudioPlayer via Speakers

    - by Mark
    I got the following code: - (id)init { if (self = [super init]) { UInt32 sessionCategory = kAudioSessionCategory_MediaPlayback; AudioSessionSetProperty(kAudioSessionProperty_AudioCategory, sizeof(sessionCategory), &sessionCategory); UInt32 audioRouteOverride = kAudioSessionOverrideAudioRoute_Speaker; AudioSessionSetProperty (kAudioSessionProperty_OverrideAudioRoute,sizeof (audioRouteOverride),&audioRouteOverride); [[AVAudioSession sharedInstance] setDelegate:self]; [[AVAudioSession sharedInstance] setCategory:AVAudioSessionCategoryPlayAndRecord error:nil]; [[AVAudioSession sharedInstance] setActive:YES error:nil]; } return self; } But somehow the sound does not want to come out of the speakers, can someone see what I am doing wrong? The code I use for playing is: AVAudioPlayer *player = [[AVAudioPlayer alloc] initWithContentsOfURL:soundFilePathURL error:nil]; [player prepareToPlay]; [player setVolume:1.0]; [player play];

  • Proper usage (best practices) of Browsable attribute in .NET for runtime grid component behavior

    - by Dan
    I understand how Browsable attribute is supposed to work. It's supposed to hide a property from showing up in a PropertyGrid in design time. It also has another effect in that it will stop a Property from showing up in components such as Grids, or specifically Infragistics WinGrid. I am not sure if it has this behaviour on regular Windows Forms grids. This works, but it doesn't sound like Browsable is being use as intended when being used for 'Run time' displaying of a property on a grid component. Any literature from Microsoft on proper use. Even though it works, I don't want to use this attribute to hide columns on a grid bound to a business object if it's not indeed the correct usage of the attribute, but rather something some grid vendors decided to use to determine property visibility on their grids.

  • Career Day in kindergarten: how to demonstrate programming in 20 minutes?

    - by Péter Török
    I was invited to the kindergarten group of my elder daughter to talk, and aswer the kids' questions, about my profession. There are 26 kids of age 4-6 in the group (plus 3 teachers who are fairly scared of anything related to programming and IT themselves, but bold enough to learn new tricks). I would have about 20-30 minutes, without projector or anything. (They have an old computer though, which by its look may be a 486, and I am not even sure if it's functioning.) My research turned up excellent earlier threads, with lots of good tips: How would you explain your job to a 5-year old? Career Day: how do I make “computer programmer” sound cool to 8 year olds? What things can I teach a group of children about programming in one day? My situation is different from each of the above though. So any advice on how to teach the kids (and their teachers) in a fun way about programming is appreciated.

  • Synonym for "Many-to-Many" relationship (relational databases)

    - by Byron
    What's a synonym for a "many-to-many" relationship? I've finished writing an object-relational mapper but I'm still stumped as to what to name the function that adds that relation. addParent() and addChild() seemed quite logical for the many-to-one/one-to-many and addSuperclass() for one-to-one inheritance, but addManyToMany() would sound quite unintuitive to an object-oriented programmer. addSibling() or addCousin() doesn't really make sense either. Any suggestions? And before you dismiss this as a non-programming question, please remember that consistent naming schemes and encapsulation are pretty integral to programming :)

  • How to prevent DOS attacks using image resizing in an ASP.NET application?

    - by Waleed Eissa
    I'm currently developing a site where users can upload images to use as avatars, I know this makes me sound a little paranoid but I was wondering what if a malicious user uploads an image with incredibly large dimensions that will eat the server memory (as a DOS attack), I already have a limit on the file size that can be uploaded (250 k) but even that size can allow for an image with incredibly large dimensions if the image for example is a JPEG that contains one color and created with a very low quality setting. Taking into consideration that the image is uploaded as a bitmap in memory when being resized (ie. not compressed), I wonder if such DOS attacks occur, even to check the image dimensions it has to be uploaded in memory first, did you hear about any attacks that exploited this? Am I too worried?

  • MVC architectural question - Where should payment processing go?

    - by Keltex
    This question is related to my ASP.NET MVC 2 development, but it could apply to any MVC environment and a question of where the logic should go. So let's say I have a controller that takes an online payment such as a shopping cart application. And I have the method that accepts the customers' credit card information: public class CartController : Controller CartRepository cartRepository = new CartRepository() [HttpPost] public ActionResult Payment(PaymentViewModel rec) { if(!ModelState.IsValid) { return View(rec); } // process payment here return RedirectToAction("Receipt"); } At the comment process payment here should the payment processing be handled: In the controller? By the repository? Someplace else?

  • Are these good interview questions for Flex developer?

    - by Ivan Belov
    I am responsible for creating a team, which will build a Flex application. Unfortunately I have zero experience with Flex. So I found an expert within our company to interview candidates. Our expert came up with the following questions: how to write item renderers explain methods commitProperties, updateDisplayList, measure binding positive / negative parts, problems with binding what is ClassFactory ? And why is it needed ? how callLater works ? what is layoutChrome ? what is skin ? did you use autogeneration for Java backend ? how to override managers ? like PopupManager . These sound a little too specific for my taste. Would you say they are decent questions? Is it fair to say, for example, that if Flex developer does not know how to write item renderer, he has very little knowledge of Flex?

  • Is there some smart way of customizing ajax message text in jQuery?

    - by Fedor
    I have tons of ajax components on this booking engine. I need to customize the text inside of the modal for each of the components to suite. I added: $('#loader').bind('ajaxStart', function() { $(this).show().addClass('modalOpen'); }).bind('ajaxComplete', function() { $(this).removeClass('modalOpen').hide() }); Is there some advanced way of changing the text inside of the loading element before I do separate .ajax calls? Or do I just have to manually do something like $('#loader').text('blah'); $.ajax({}) Furthermore, this may sound silly but is there a way to not have the loader show up for certain components? If not I imagine I'll have to do something like $('someel').someEvent(function() { $('#loader').addClass('override-hide'); $.ajax({ success:function() { $('#loader').removeClass('override-hide'); } }) }) #loader.override-hide { display:none !important; }

  • How can HTML5 "replace" Flash?

    - by Kassini
    A topic of debate that's seen a resurgence since the unveiling of the iPad is the issue of Flash versus HTML5. There are those that suggest that HTML5 will one day supplant/replace Adobe Flash. I do not develop software that runs in a browser, so my (limited) understanding is: HTML is a pure-text markup language that is delivered over HTTP to a client browser. The client browser interprets the markup and renders (with varying degrees of success) the page according to an standard specification. Adobe Flash is a propriety framework for working with audio, video, sound and raster/vector graphics. It requires special authoring tools (a compiler perhaps?) and a custom player that's available as a plug-in to most common browsers. Could someone please explain (to this C/C++ developer) how it is possible from a technical/coding point-of-view that a text-based markup language (HTML5) could be considered a replacement to a multimedia framework (Flash)? Please no opinionated arguments - just technical facts.

  • Does anyone have any EPiServer Exam Tips?

    - by gilles27
    Myself and some colleagues have just been told that we are all taking the EPiServer CMS certification exam on Friday. Having done some research on the web it does sound like a challenging exam - I've heard that only one in six people pass it. There doesn't seem to be much in the way of learning material, beyond what is described on the EPiServer site, this blog post and this blog post. Has anyone else out there passed recently and if so can they provide any hints or tips? Any help would be appreciated.

  • Intergration of checkout badges into an order form

    - by Reno
    Hi Does anyone know how to integrate several checkout badges into an order form? It might sound obvious to all (or most) but within the html wouldn't the form tag have an action to just one of the online merchants and not all? For example? I would like to have a basic order form which collects a users name, email, uploaded files, project details, and a few packages to choose from. Once they have selected the package most appropriate to them? They would be given a total cost and asked to pay via Paypal, Google Checkout OR Moneybookers. Can anyone help me out on this? Or point me in the direction where I can obtain further knowledge? Thanks in advance. Reno

  • How to get mp3 files to play in iPhone Safari web browser?

    - by grrussel
    How can I get an MP3 audio file to play in iPhone Safari (OS 3.1)? Currently, I am generating HTML e.g. <a href="file.mp3"><img src="sound.png" alt="Play audio"/></a> to play the file on clicking on the nested image. This works on Safari on OSX, but not on the iPhone. There, the content of the file is shown as text, but it does not appear to be a mime-type problem when checked with Live HTTP Headers from Firefox. I have found approaches referenced here. These require the Safari Plugins setting to be on in the preferences, which is why it did not previously work for me.

  • 2 AudioQueue questions

    - by iter
    I am learning to use AudioQueue. I wish to generate an audio stream programmatically. I have 2 issues that I cannot account for. I am getting audio when I run in the simulator, but not on an iPhone. (Other apps do produce sound on the phone). I get about 20ms-long gaps of silence between buffers. In my testing, I generate an audio buffer on startup and repeatedly enqueue it without modification. I don't spend any processing on filling audio buffers at runtime, not even copying them. Ari.

  • Arguments On a Console eMbedded Visual C++ Application

    - by Nathan Campos
    I'm trying to develop a simple application that will read some files, targeted for Windows CE. For this I'm using Microsoft eMbedded Visual C++ 3. This program(that is for console) will be called like this: /Storage Card/Test coms file.cmss As you can see, file.cmss is the first argument, but on my main I have a condition to show the help(the normal, how to use the program) if the arguments are smaller than 2: if(argc < 2) { showhelp(); return 0; } But when I execute the program on the command-line of Windows CE(using all the necessary arguments) I got the showHelp() content. Then I've checked all the code, but it's entirelly correct. But I think that eVC++ don't use argc and argv[] for arguments, then I want some help on how to determine the arguments on it.

  • Crashes when using AVAudioPlayer on iPhone

    - by mindthief
    Hi all, I am trying to use AVAudioPlayer to play some sounds in quick succession. When I invoke the sound-playing function less frequently so that the sounds play fully before the function is invoked again, the application runs fine. But if I invoke the function quickly in rapid succession (so that sounds are played while the previous sounds are still being played), the app eventually crashes after ~20 calls to the function, with the message "EXC_BAD_ACCESS". Here is code from the function: NSString *nsWavPath = [[[NSBundle mainBundle] resourcePath] stringByAppendingPathComponent:wavFileName]; AVAudioPlayer* theAudio = [[AVAudioPlayer alloc] initWithContentsOfURL:[NSURL fileURLWithPath:nsWavPath] error:NULL]; theAudio.delegate = self; [theAudio play]; As mentioned in another thread, I implemented the following delegate function: - (void) audioPlayerDidFinishPlaying:(AVAudioPlayer *)player successfully:(BOOL)flag { if(!flag) NSLog(@"audio did NOT finish successfully\n"); [player release]; } But the app still crashes after around ~20 rapid calls to the function. Any idea what I'm doing wrong?

  • Possible typos in ECMAScript 5 specification?

    - by Andy West
    Does anybody know why, at the end of section 7.6 of the ECMA-262, 5th Edition specification, the nonterminals UnicodeLetter, UnicodeCombiningMark, UnicodeDigit, UnicodeconnectorPunctuation, and UnicodeEscapeSequence are not followed by two colons? From section 5.1.6: Nonterminal symbols are shown in italic type. The definition of a nonterminal is introduced by the name of the nonterminal being defined followed by one or more colons. (The number of colons indicates to which grammar the production belongs.) Since lexical productions are distinguished by having two colons, and this is under "Lexical Conventions", I'm assuming that they meant to put the colons in. Does that sound right? Just making sure that these really are nonterminals and they really are part of the lexical grammar. EDIT: I noticed there have been votes to close this. Just to make my case about why this is programming-related, it is relevant to anyone wanting to implement an ECMAScript interpreter.

  • IOKit header assert.h gone? [answered]

    - by Julian Kessel
    I want to get the hardware address of my mac's ethernet card. In all samples I saw in include on IOKit/assert.h . Which doesn't seem to exist on my system. GCC throws an error saying he doesn't know the type IOEthernetAddress. Is assert.h necessary for my task? It would be great if someone coud give me a working sample. [edit] here's my code, think this will help understanding the problem: #include <IOKit/assert.h> #include <IOKit/network/IOEthernetController.h> #include <IOKit/network/IOEthernetInterface.h> int main(){ IOEthernetAddress addr; getHardwareAddress(&addr); printf("%x", addr); return 0; }

  • Is there a more efficient way to get the number of search results from a google query?

    - by highone
    Right now I am using this code: string url = "http://www.google.com/search?sourceid=chrome&ie=UTF-8&q=hey&esrch=FT1"; string source = getPageSource(url); string[] stringSeparators = new string[] { "<b>", "</b>" }; string[] b = source.Split(stringSeparators, StringSplitOptions.None); bool isResultNum = false; foreach (string s in b) { if (isResultNum) { MessageBox.Show(s.Replace(",", "")); return; } if (s.Contains(" of about ")) { isResultNum = true; } } Unfortunately it is very slow, is there a better way to do it? Also is it legal to query google like this? From the answer in this question it didn't sound like it was http://stackoverflow.com/questions/903747/how-to-download-google-search-results

  • Linking to an Apache License 2.0 library and distributing with proprietary application

    - by atnakjp
    Hi all, I've read through "Apache License, Version 2.0" but my interpretation was in slightly different to an answer given in a related question so was hoping for some clarification. Supposing I created an application that linked to a library that was licensed under the license in question, my interpretation for doing what's required is: I don't need to do anything special to the application itself because it's considered neither "Work" nor "Derivative Works". When distributing the library alongside the application, I need to include a copy of the license. Any installer that contains the library would be considered "Derivative Works" and therefore I would need to show the attribution notices contained in "NOTICE" (if one exists) in one of its screens. If I were to distribute everything in a zip file instead, I would need to put the same attribution notices in a text file that I distribute alongside the file. Does this sound about right? Cheers,

  • Monotouch Binding to Linea Pro SDK

    - by jeffrapp
    I'm trying to create a binding to the Linea Pro (it's the barcode scanner they use in the Apple Stores, Lowes) SDK. I'm using David Sandor's bindings as a reference, but the SDK has been updated a few times since January of 2011. I have most everything working, except for the playSound call, which is used to, well, play a sound on the Linea Pro device. The .h file from the SDK has the call as follows: -(BOOL)playSound:(int)volume beepData:(int *)data length:(int)length error:(NSError **)error; I've tried using int[], NSArray, and an IntPtr to the int[], but nothing seems to work. The last unsuccessful iteration of my binding looks like: [Export ("playSound:beepData:length:")] void PlaySound (int volume, NSArray data, int length); Now, this doesn't work at all. Also note that I have no idea what to do with the error:(NSError **)error part, either. I am lacking some serious familiarity with C, so any help would be extremely appreciated.

  • How to get smartcard reader name in Windows 7 using C#?

One of the functions of the .dll uses name of the reader as argument. My problem is that I don't know how to get the name. After looking for answers I found something similar to what I need in an example here: http://msdn.microsoft.com/en-us/library/aa379803%28VS.85%29.aspx I'm looking for a way to get szReader value as described in the aforementioned example using C#. Can anyone help me or at least point me in the right direction?

  • How do I change the on-screen keyboard for a PasswordBox

    I have a box that I want to take a password of only numbers (like an ATM-card PIN), how is the best way to do that? Requirements: Password (with the hidden numbers) Typing digits as the default (only?) keyboard What I've tried: I thought that InputScopes would be the way to go, but I can't set the input scope on a password box. I even tried putting the password InputScope on a normal TextBox, but that didn't mask the appearance of the characters in the text box. Suggestions?
