  • PHP/Zend: How to force browsers to don't show warnings on webpage for a particular case?

    - by NAVEED
    I trying to get twitter updates like this: try { $doc = new DOMDocument(); $doc->load('http://twitter.com/statuses/user_timeline/1234567890.rss'); $isOK = true; } catch( Zend_Exception $e ) { $isOK = false; } If there is not problem with internet connection then $isOK = true; is set. But if there is a problem in loading twitter page then it shows following warnings and does not set $isOK = false; Warning: DOMDocument::load(http://twitter.com/statuses/user_timeline/1234567890.rss) [domdocument.load]: failed to open stream: HTTP request failed! HTTP/1.1 404 Not Found in /var/www/vcred/application/controllers/IndexController.php on line 120 I don't want to see above warning on my webpage in any case. Any idea? Thanks

  • Linker Error: iPhone Unit Test Bundle referencing App classes

    - by ohhorob
    Starting with an app already in development, I have carried out the instructions in the iPhone Development Guide – Unit Testing Applications I can successfully include and use my App's classes in Application-style tests that run on the device, and output their results to the console. If I add the following line of code: STAssertTrue([viewController isKindOfClass:[LoginViewController class]], @"Top view controller is not LoginViewController"); The following build error is generated: Undefined symbols: "_OBJC_CLASS_$_LoginViewController", referenced from: __objc_classrefs__DATA@0 in LoginViewTest.o ld: symbol(s) not found collect2: ld returned 1 exit status I can provide more configuration information for the project and the Testing target, but the setup works file without the [LoginViewController class] line in the test source. Without that line, I can reference the class, use it's properties and send it messages successfully. Is there a linking build setting, or bundle loading option that is required when attempting to use an App class in this fashion? Or should I find another type of test to confirm that the class of an object is the expected one?

  • Any way to have delayed_job execute some run-once code at startup and use across all jobs?

    - by Rob Cameron
    So I've got a delayed_job task that pushes some info to an XMPP server. Ideally you create a connection to XMPP once and then constantly push data to it, rather than creating a new connection every time you have some data to send. Is there any kind of facility in delayed_job for running a sort of 'setup' method when a worker starts, have it set some instance variables (like the XMPP connection object) that can then be used by all the jobs that come up? It's okay if each worker runs its own setup method. I just don't want every job (thousands per day) connecting to the XMPP server from scratch every time. Thanks for any help!

  • Retrieve baseUri w/o resorting to Application.Current

    - by beaudetious
    My custom controls are not loading in VS.NET's designer because of a null reference exception. It's got everything to do with the way I am retrieving the baseUri of the application when it runs in the browser: _uriPrefix = Application.Current.Host.Source.AbsoluteUri.Substring(0, Application.Current.Host.Source.AbsoluteUri.IndexOf("/ClientBin")).Trim(); According to the exception details and the help file I'm directed to (here) I'm not correctly designing my app for a runtime that's not the browser (i.e. the new WPF editor in VS.NET or Expression Blend). So, the question is how do retrieve the baseUri (the http://localhost:#### part of my application) if I can't use Application.Host which apparently is null during design time? is there a safe way to do this so I can load my custom controls in a designer?

  • Best cheap GUI for converting to f4v

    - by Ben
    Hi, I need to give one client the ability to convert some videos to f4v h264 before loading it up to an AIR app. I normally doing with the Adobe Media Encoder CS4 but that only ships with adobe products (you can't download it as a free standalone app - which, start rant is odd, you'd think they would push the format - Microsoft's competing expresssion encoder is free end rant) Anyway, I need to get a (hopefully not too expensive, but willing to pay for it) good 3rd part app that can take any video and convert it to an f4v. Can you suggest any? Everything i've found is horrible or jammed with ads and crap. What would you use? Any suggestion? (please don't just say ffmpeg - I know it can do it but we need to good simple GUI) Thanks!

  • A pragmatic view on private vs public

    - by Denis Gorbachev
    Hello everybody! I've always wondered on the topic of public, protected and private properties. My memory can easily recall times when I had to hack somebody's code, and having the hacked-upon class variables declared as private was always upsetting. Also, there were (more) times I've written a class myself, and had never recognized any potential gain of privatizing the property. I should note here that using public vars is not in my habit: I adhere to the principles of OOP by utilizing getters and setters. So, what's the whole point in these restrictions?

  • Create a triangle out of stars using only recursion

    - by Ramblingwood
    I need to to write a method that is called like printTriangle(5);. We need to create an iterative method and a recursive method (without ANY iteration). The output needs to look like this: * ** *** **** ***** This code works with the iterative but I can't adapt it to be recursive. public void printTriangle (int count) { int line = 1; while(line <= count) { for(int x = 1; x <= line; x++) { System.out.print("*"); } System.out.print("\n"); line++; } } I should not that you cannot use any class level variables or any external methods. Thanks.

  • How does an interpreter switch scope?

    - by Dox
    I'm asking this because I'm relatively new to interpreter development and I wanted to know some basic concepts before reinventing the wheel. I thought of the values of all variables stored in an array which makes the current scope, upon entering a function the array is swapped and the original array put on some sort of stack. When leaving the function the top element of the "scope stack" is popped of and used again. Is this basically right? Isn't swapping arrays (which means moving around a lot of data) not very slow and therefore not used by modern interpreters?

  • NSURL not instantiating properly

    - by taokakao
    Hi, I am new to IPhone developing. I have got very strange issue with NSURL which is driving me crazy. I want to instantiate NSURL object to use it in loading image. But instantiation never happens in proper way. It always says my url in invalid. Basically I use code like below: NSString *str = @"http://google.com"; NSURL *url = [NSURL URLWithString:str]; but I also have tried a lot of different modifications (with CFStringRef + CFURLCreateStringByAddingPercentEscapes and so on). All of them are not working for me. In debugger url is set to "Invalid". What it could be? I don't think this is algorithmic or environment issue. It could be about some settings? Have anyone any idea of what happens?

  • Create custom component based on LinearLayout, declaring layout in XML

    - by pheelicks
    I've been trying to create a Compound Control in Android 1.5 (as described here) but havn't been able to find any good examples on how to do this using an XML file to specify a layout. I'm fine with creating an Activity and then loading an xml file using the following in the constructor: setContentView(R.layout.main); However, I want to do this in subclass of LinearLayout - so I can use this compound component in other XML layouts. Something along the lines of: public class CustomView extends LinearLayout { public CustomView(Context context) { super(context); setupView(); } public CustomView(Context context, AttributeSet attrs) { super(context, attrs); setupView(); } public void setupView() { setContentView(R.layout.custom); // Not possible } } What is the correct way of going about doing this?

  • Javascript Popup Windows

    I have a popup window code that I have used before in login forms. The code displays an in-page popup. This is the code: <?php //In Page Popup Box with Faded Background by Jerry Low @crankberryblog.com //Find other useful scripts at the Crankberry Blog //SETTINGS $fade_amount = 60; //In Percentage $box_width = 400; $box_background = 'FFFFFF'; //Hex Color $box_border_width = 2; $box_border_color = '999999'; //Hex Color $close_box = 1; //Do You Want The Close Bar on Top 1 = Yes, 0 = No $extension = ""; // Other Variables that maybe needed, page number etc. //Begin Popup Box $left_margin = ( 0 - ($box_width*0.5) ); $page_url = basename($_SERVER['PHP_SELF']); if ($extension!="") $page_url .= '?' . $extension; if (isset($_GET['popup'])) { echo '<div class="popup" style="width:'.$box_width.'px; background: #'.$box_background.'; margin-left:'.$left_margin.'px;'; if ($box_border_width>1) echo ' border: '.$box_border_width.'px solid #'.$box_border_color.';'; echo '">'; //Close Box if ($close_box===1) echo '<div class="popup_close"><a href="'.$page_url.'">Close (x)</a></div>'; ?> <!–- START YOUR POPUP CONTENT HERE -–> Popup content goes in here! <!–- END OF YOUR POPUP CONTENT HERE -–> <?php echo '</div> <div class="fade" onclick="location.replace(\''.$page_url.'\');" style="opacity: 0.'.$fade_amount.'; -moz-opacity: 0.'.$fade_amount.';filter: alpha(opacity: '.$fade_amount.');"></div> <div class="fade_container">'; } ?> <a href="?popup=1<?php if ($extension!="") echo '&' . $extension; ?>">Activated Box</a> This code contains a link that reloads the page with parameters/arguments to show the popup.

  • Can't correctly stream x264 video to mobile via RTSP

    - by Andrew
    Hello! I'm trying to stream video compressed with x264 and NeroAAC and hinted with MP4Box. When i'm playing it with VLC player streaming works fine, as expected. When i'm trying to open URL with my HTC Hero, it switches to player mode, then starts "loading video" animation, then after some time it shows "unable to connect to server". Sample movies provided with DSS streamed fine regardless bitrate. I tried few encoding options, but always the same result. I suspect nocabac and level=11 but it didn't changed nothing. Is there some more specific encoding options for such type? Thank You!

  • For what purpose does java have a float primitive type?

    - by Roman
    I heard plenty times different claims about float type in java. The most popular issues typicaly regard to converting float value to double and vice versa. I read (rather long time ago and not sure that it's actual now with new JVM) that float gives much worse performance then double. And it's also not recommended to use float in scientific applications which should have certain accuracy. I also remember that when I worked with AWT and Swing I had some problems with using float or double (like using Point2D.Float or Point2D.Double). So, I see only 2 advantages of float over double: it needs only 4 bytes while double needs 8 bytes JMM garantees that assignment operation is atomic with float variables while it's not atomic with double's. Are there any other cases where float is better then double? Do you use float's in your applications? It seems to me that the only valuable reason java has float is backward compatibility.

  • Inline function and calling cost in C

    - by Eonil
    I'm making a vector/matrix library. (GCC, ARM NEON, iPhone) typedef struct{ float v[4]; } Vector; typedef struct{ Vector v[4]; } Matrix; I passed struct data as pointer to avoid performance degrade from data copying when calling function. So I thought designed function like this: void makeTranslation(const Vector* factor, Matrix* restrict result); But, if function is inline, is there any reason to pass values as pointer for performance? Do those variables copied too? How about register and caches? inline Matrix makeTranslation(Vector factor) __attribute__ ((always_inline)); How do you think about calling costs of each cases?

  • C++ word to bytes

    - by Vit
    Hi, I tried to read CPUID using assembler in C++. I know there is function for it in , but I want the asm way. So, after CPUID is executed, it should fill eax,ebx,ecx registers with ASCII coded string. But my problem is, since I can in asm adress only full, or half eax register, how to break that 32 bits into 4 bytes. I used this: #include <iostream> #include <stdlib.h> int main() { _asm { cpuid /*There I need to mov values from eax,ebx and ecx to some propriate variables*/ } system("PAUSE"); return(0); }

  • About the fix for the interference between Company mode and Yasnippet

    - by janoChen
    Emacs wiki says: Company does interfere with Yasnippet’s native behaviour. Here’s a quick fix: http://gist.github.com/265010 The code is the following: (define-key company-active-map "\t" 'company-yasnippet-or-completion) (defun company-yasnippet-or-completion () (interactive) (if (yas/expansion-at-point) (progn (company-abort) (yas/expand)) (company-complete-common))) (defun yas/expansion-at-point () "Tested with v0.6.1. Extracted from `yas/expand-1'" (first (yas/current-key))) I placed that code in my .emacs and the following message appeared: Warning (initialization): An error occurred while loading `c:/Documents and Settings/Alex.AUTOINSTALL.001/Application Data/.emacs.elc': Symbol's value as variable is void: company-active-map To ensure normal operation, you should investigate and remove the cause of the error in your initialization file. Start Emacs with the `--debug-init' option to view a complete error backtrace. Do I have to place the fix code inside a YASnippet's .el file? or in my .emacs (which throws me an error)?

  • Is it any desktop wysiwyg editors for mediawiki / wiki available?

    - by Eye of Hell
    Hello. Mediawiki is very good, but for programming tasks editing it via web is not very handy since wysiwyg is very limited, pressing 'edit' + 'publish' on any small change and waiting for page loading kins of annoying. I have seen alot of desktop wikis (personal wikis) that are free from such problems. The best example is a 'wikidpad' that has a usage patter of 'focus, edit wiki in-place, minimize'. This is very handy for programming work where you need to make small changes to wiki and documentation during development, and documentation is written much more often than readed :). But all such desktops wikies are personal - they don't have any wiki sharing (or marginally limited support for it). So, maybe it's a desktop application exists that can connect to mediawiki and allows to view and edit it via a rich wysiwyg editor? Any hints are welcomed.

  • press button to open web page from app

    - by Lee
    I have an app that I want to interact with a web page. Basically I want to press a button and the web page will open in a new view... Sorry I wasn't clear, I am developing on a Mac for an iPhone. Currently I have a "locate me" app that displays your Latitude and Longitude. I want to use those variables to populate 2 of the blanks on a PHP web page/form I have developed. I have added a label and button to my current app, when the button is pressed the URL with the Lat and Long (as passed vars) are displayed in the label. I want those vars to appear on my web page. Hope this is clearer... Solved: I just added these lines of code I found here: NSURL *url = [ [ NSURL alloc ] initWithString: @"http://www.cnn.com" ]; [[UIApplication sharedApplication] openURL:url];

  • Protocol buffer deserialization and a dynamically loaded DLL in Compact Framework

    - by cloudraven
    I saw a question related to this on the full framework here. Since it seems to have stayed unresolved for quite a while and this is for the compact framework, I though it would be better to create a new question for it. I want to deserialize types for which I am loading assemblies dynamically (with Assembly.LoadFrom) and I am getting a "Unable to identify known-type for ProtoIncludeAttribute" error. In the related question I mentioned, it was hinted that hooking AppDomain.AssemblyResolve event would help solving the problem. It makes sense for the full framework, but that event is not available in the CF. I wonder if there is a way to do this with CF. The structures I am using look a lot like this and all the classes required for deserialization are loaded from the same Assembly. If the assembly is referenced instead of dynamically loaded it works fine, but fails if done dynamically.

  • How to use JarOutputStream to create a JAR file?

    - by Gili
    How does one create a JAR file programmatically using java.util.jar.JarOutputStream? The JAR file produced by my program looks correct (it extracts fine) but when I try loading a library from it Java complains that it cannot find files which are clearly stored inside it. If I extract the JAR file and use Sun's jar command-line tool to re-compress it the resulting library works fine. In short, something is wrong with my JAR file. Please explain how to create a JAR file programmatically, complete with a manifest file.

  • local match kickoff time

    - by Usagi Dreamy
    I'm working on a sports website and need to convert the server's match start time to local match start time. After much googling, I figured the fastest and most accurate way is to get the GMT offset value in JavaScript. The trouble is, I can't pass the GMT offset value to PHP. I've tried using both the PHP session and cookie variables, but both are always empty. The website doesn't require a user account, so there isn't any stored GMT value in the database. I'm trying to auto-detect each user's local timezone every time he/she visits the website, and then calculate the local match start time based on the timezone offset. Can someone please advise me? Thanks.

  • Static vs Non Static constructors

    - by Neil N
    I can't think of any reasons why one is better than the other. Compare these two implementations: public class MyClass { public myClass(string fileName) { // some code... } } as opposed to: public class MyClass { private myClass(){} public static Create(string fileName) { // some code... } } There are some places in the .Net framework that use the static method to create instances. At first I was thinking, it registers it's instances to keep track of them, but regular constructors could do the same thing through the use of private static variables. What is the reasoning behind this style?

  • Komodo IDE 6's slow autocomplete problems with Javascript

    - by skerit
    I've been trying out Komodo IDE 6 for the last few days. I've always liked Komodo but I'm starting to get annoyed by something: The autocomplete is way too slow/buggy. Certain variables just won't give any autocomplete tips. Sometimes you have to backspace the dot and try over and over again. It also has a hard time giving autocomplete info for an object that has been created using a class in a namespace. Has anyone else had any problems with these things? Are there any better alternatives?

    I'm trying to produce a single variable which is a concatenation of two chars e.g to go from "p30s4" "p28s4" to "p30s4 p28s4". I've tried cat and paste as shown below.
