  • How to print element values when iterating through XML document in PHP

    - by pharma_joe
    I am iterating through the results of a service call to yahoo news thus: //Send service request if (!$yahooResults = file_get_contents($yahooRequest)) { echo 'Error processing service request'; } //Read result into xml document $yahooResultXml = new DOMDocument('1.0', 'UTF-8'); $yahooResultXml-loadXML($yahooResults); //Build page include_once('components/pageHeader.php'); echo 'Search Results'; //echo $yahooResultXml-saveHTML(); //Iterate over each Result node $stories = $yahooResultXml-getElementsByTagName('Result'); foreach ($stories as $story) { //Title //Summary //Url //Source //Language //Publish Date //Modification Date } include_once('components/pageFooter.php'); Each Title is in a Title node within a Result Node. I cannot figure out how to simply echo the content of the Title node!

  • serial port close hangs in compact frame work 3.5

    - by ananda
    I have developed the application for windows mobile 5.0 and .net compact framework 2.0 sp2. This application communicates to the hardware device using serial port. This application works fine in windows mobile 5.0 based PDAs. I have handled data received event to get the data from serial port. But when I run my application on windows mobile 6.1 and .net compact framework 3.5, my application hangs on serial port close API call. There are many workarounds mentioned in the .net compact framework blog like (closing the com port on different thread, opening the port in the beginning of the application and close once application exists, polling for data instead of event handling), but nothing is working consistently.

  • iPhone app rejected because of Beta word is used

    - by arielcamus
    Hi, I was using the text "We are currently on Beta. Please, enter our website and ask for an invitation" when a user click on "Register" on our app. However, Apple has rejected our app because it can not has any disabled featured and can not contains word "Beta". What would you do in this situation? I don't know if hide this option and show it only when an API call response says "registerEnabled = YES" or just change the text and use: "You need and invitation to access OUR_APP. Visit our website to get one." Except for registering, our app is fully functional. Thank you, A

  • UISlider disappearing when calling setValue with 0

    - by Kai
    I have several UISliders in my application which all work fine until I call the following code: ... frame = CGRectMake(43, 210, 201, 23); mySlider = [[UISlider alloc] initWithFrame:frame]; [mySlider addTarget:self action:@selector(sliderUpdate:) forControlEvents:UIControlEventValueChanged]; mySlider.minimumValue = 0.0; mySlider.maximumValue = 1.0; mySlider.continuous = YES; tempNum = [myArray objectAtIndex:2]; mySlider.value = [tempNum floatValue]; // only breaks if value is 0 [self.view addSubview:mySlider]; ... For some reason the slider doesn't show up unless mySlider.value is set to greater than 0. The only workaround I've found so far is to set it to an extremely small value (such as 0.000000001), which makes the slider appear as expected. Does anyone have any idea why this might be happening and how it can be fixed?

  • Delphi: how to efficently read a big binary file, converting it to hexadecimal for passing it as a v

    - by user193655
    I need to convert a binary file (a zip file) into hexadecimal representation, to then send it to sql-server as a varbinary(max) function parameter. A full example (using a very small file!) is: 1) my file contains the following bits 000011110000111 2) I need a procedure to QUICKLY convert it to 0F0F 3) I will call a sql server function passing 0x0F0F as parameter The problem is that I have large files (up to 100MB, even if average file size is 100KB files are possible), so I need the fastest way to do this. Otherwise stated: I need to create the string '0x'+BinaryDataInHexadecimalRepresentation in the most efficient way. Related question: passing hexadecimal data to sql server

  • Can't resolve CalledFromWrongThreadException with Handler

    - by michel
    I will try to keep it simple: In my main activity I make a handler: public class ARViewer extends ARDisplayActivity { public final MHandler mHandler = new MHandler(this); public void onCreate(Bundle savedInstanceState) { ... The class MHandler: public final class MHandler extends Handler{ //main activity private ARViewer arnv; public MHandler(ARViewer arnv){ this.arnv = arnv; } @Override public void handleMessage(Message msg) { ... case H_RR : arnv.setContentView(R.layout.routeplanner); break; ... super.handleMessage(msg); } } But if I call the handleMessage method from a callback function in a other Class, definitely from a other thread, I still get the exception message: CalledFromWrongThreadException (Only the original thread that created a view hierarchy can touch its views) : public void rFound(Route route) { Message msg = new Message(); msg.what = MHandler.H_RR; ARViewer.arnv.mHandler.handleMessage(msg); }

  • Trying to load a DLL with LoadLibrary and get R6034 "An application has made an attempt to load the

    - by nonoitall
    I'm writing a wrapper program that loads Winamp input plugins. I've got it working well so far with quite a few plugins, but for some others, I get an error message at runtime when I attempt to call LoadLibrary on the plugin's DLL. (It seems to happen mostly with plugins that were included with Winamp.) A dialog appears and gives me the error code and message above. This happens, for example, with the in_flac.dll and in_mp3.dll plugins (which come with Winamp). Any ideas on how I can remedy this situation?

  • How to extracting individual dimensions from $node->content['dimensions'] in Drupal's Ubercart?

    - by Walden
    On my Ubercart node-product.tpl.php page, I am trying to extract the individual product dimensions (height, weight, length) from the more generic: print $node->content['dimensions'] ['#value']; which returns "Dimensions: 72in. × 42in. × 30in." Using var_dump(get_defined_vars()); I'm able to see that the dimensions are being outputted independently, but can't seem to get them to print. on the page. What is the proper way to call the dimensions individually?

  • localtime_r supposed to be thread safe, but causing errors in Valgrind DRD

    - by Nik
    I searched google as much as I could but I couldn't find any good answers to this. localtime_r is supposed to be a thread-safe function for getting the system time. However, when checking my application with Valgrind --tool=drd, it consistantly tells me that there is a data race condition on this function. Are the common search results lying to me, or am I just missing something? It doesn't seem efficient to surround each localtime_r call with a mutex, especially if it is supposed to by thread safe in the first place. here is how i'm using it: timeval handlerTime; gettimeofday(&handlerTime,NULL); tm handlerTm; localtime_r(&handlerTime.tv_sec,&handlerTm); Any ideas?

  • DB4o Linq query - How to check for null strings

    - by Dave
    Hey there - simple query: var q = (from SomeObject o in container where o.SomeInt > 8 && o.SomeString != null //Null Ref here select o; I always get a null reference exception. If I use String.IsNullOrEmpty(o.SomeString) the query takes about 100 times as long, as if I use && o.SomeString != "" (which is way faster, but obviously not correct). I'm guessing because DB4o needs to activate the objects, in order to pass them in to the IsNullOrEmpty call, and can't use the indexes. My question is, what's a better way to check for nulls in this situation? Is there something like: mystring != Db4o.DBNull.Value, or something? Cheers, Dave

  • Limit on FileReference uploads?!

    - by Rudy
    Hello, I am currently uploading files in ActionScript 3 using the upload() method of the FileReference class. I built an uploader than can do simultaneous or parallel uploads, having a variable set the number of maximum uploads at a time. I noticed that for Internet Explorer I could be uploading 10 or more files simultaneously, but FireFox and Safari seems to cap the number of uploads to 2. That is, when I call the upload method on per say, 3 files, only 2 will get events back (such as ProgressEvent.PROGRESS). Only when one of the 2 uploads finishes, then the 3rd one will start. This behavior does not happen for Internet Explorer. I have tried with a large number of files, and some big files, to make sure this behavior was consistent. I was wondering if anyone noticed this behavior please, and if so, what is the reason for this behavior please? I appreciate your help, Thank you very much, Rudy

  • Scaling Java applications - existing cluster-aware IoC frameworks?

    - by Zoltan
    Most people use some kind of an IoC framework - Guice, Spring, you name it. Many of us need to scale their applications too, so they complicate their lifes with Terracotta, Glassfish/JBoss/insertyourfavouritehere clusters. But is it really the way to go? Are you using any of the above? Here's some ideas we currently have implemented in a yet-to-be-opensourced framework, and I'd like to see what you think of it, or maybe "it's a complete ripoff of XY!". cluster-wide object replication - give it a name, and whenever you do something (in any node) on such an object, it will get replicated - with different guarantees do transparent soft-loadbalancing - simplest scenario: restful webservice method call proxied to an other node view-only node injection: inject a proxy to a "named" object, and get your calls automatically proxied to a node Would you use something like that? Is there a current, stable, enterprise-ready implementation out there?

  • design using a readonly class in c#

    - by edosoft
    Hi Small design question here. I'm trying to develop a calculation app in C#. I have a class, let's call it InputRecord, which holds 100s of fields (multi dimensional arrays) This InputRecordclass will be used in a number of CalculationEngines. Each CalculcationEngine can make changes to a number of fields in the InputRecord. These changes are steps needed for it's calculation. Now I don't want the local changes made to the InputRecord to be used in other CalculcationEngine's classes. The first solution that comes to mind is using a struct: these are value types. However I'd like to use inheritance: each CalculationEngine needs a few fields only relevant to that engine: it's has it's own InputRecord, based on BaseInputRecord. Can anyone point me to a design that will help me accomplish this?

  • Formatting Log File Messages

    - by Kumar
    This is about formatting the messages for logging so as to subsequently be able to parse them relatively easily esp. given the extensive logging required in financial apps Typically a line in the log file is of the form TimeStamp: Module/Function: where the log string contains whatever you choose, typically you'd have some key=value paradigm or even johnny5 key {value} etc. A regex search through the log file might easily pick up Module/Function but enforcing and maintaing consistency on the log string itself for every developer on the team is often a pain The logging api's are typically ILog.LogInfo(string text, params object[] args) ILog.LogWarning(string text, params object[] args) ILog.LogError(string text, params object[] args) Looking for opinions on better logging api's to format the log messages where a regex search can be performed for Module/Function = Basket/AddItem TokenA = Value1 and TokenB = Value2 etc. without going over every developer's every logging call

  • SQLAlchemy declarative syntax with autoload in Pylons

    - by Juliusz Gonera
    I would like to use autoload to use an existings database. I know how to do it without declarative syntax (model/_init_.py): def init_model(engine): """Call me before using any of the tables or classes in the model""" t_events = Table('events', Base.metadata, schema='events', autoload=True, autoload_with=engine) orm.mapper(Event, t_events) Session.configure(bind=engine) class Event(object): pass This works fine, but I would like to use declarative syntax: class Event(Base): __tablename__ = 'events' __table_args__ = {'schema': 'events', 'autoload': True} Unfortunately, this way I get: sqlalchemy.exc.UnboundExecutionError: No engine is bound to this Table's MetaData. Pass an engine to the Table via autoload_with=<someengine>, or associate the MetaData with an engine via metadata.bind=<someengine> The problem here is that I don't know where to get the engine from (to use it in autoload_with) at the stage of importing the model (it's available in init_model()). I tried adding meta.Base.metadata.bind(engine) to environment.py but it doesn't work. Anyone has found some elegant solution?

  • PHP won't parse MySQL statements

    - by Hussain
    I just installed Apache 2.2.15/PHP 5.3.2/MySQL 5.1.44 on Windows Vista. Apache is working fine, PHP is functional, and MySQL works on the CLI. However, when I try to access MySQL via PHP, I get an error (Fatal error: Call to undefined function mysql_connect()). extension=php_mysql.dll and extension=php_mbstring.dll are uncommented in the php.ini file, and PHP is in the system path. There is no libmysql.dll in either the top level PHP directory or the ext directory. There's a libmySQL.dll file in the MySQL bin directory (which is also in the system path); I tried renaming it, but that doesn't do anything Also, in case anyone wants to know, I originally installed PHP using the MSI installer, but it was missing some DLLs, so I installed from the zip file. I think I've exhausted all my options. Any help on this problem would be very appreciated. Thanks in advance.

  • Advanced LINQ Update Statement

    - by user1902490
    I have a data base with Price_old like: Date --- Hour --- Price _____________________________ Jan 1 --- 1 --- $3.0 Jan 1 --- 2 --- $3.1 Jan 1 --- 3 --- $3.3 Jan 1 --- 4 --- $3.15 Jan 2 --- 1 --- $2.95 Jan 2 --- 2 --- $3.2 Jan 2 --- 3 --- $3.05 What I then have is a spreadsheet, with the same structure, that I will be reading into a datatable, I'll call the new datatable Price_New, note that price new may not have all the same date/hours as Price_Old So, I end up with 2 datatables, Price_Old, and Price_New, and what I need to do is update Price_old with the new prices in Price_New, and then commit those new prices to the Database. I am kinda new to LINQ (about 30 mins of experience) and would really appreciate if someone could give me a pointer or two on whether or not this is doing in LINQ and what the best method would be. Thanks

  • Hidden Input Elements in Firefox

    - by splatto
    I'm having troubles with fckeditor in Firefox. When the user goes to a page, the html (encoded) is stored in a hidden input element. I call the predefined fckeditor javascript event to populate my editor with the html from the hidden ContentBody element. function FCKeditor_OnComplete( editorInstance ) { editorInstance.InsertHtml(""); var sample = document.getElementById("ContentBody").value; editorInstance.InsertHtml(sample); } This automatically populates the editor with the desired text in IE, but in Firefox it doesn't. Firebug gives me the error : A is null [Break on this error] var FCKW3CRange=function(A){this._Docume...eateFromRange(this._Document,this);}};\r\n Using Firebug I can determine that the event method FCKeditor_OnComplete() just isn't fired when using Firefox. It is, however, in IE. Any ideas on how to get this to work in both browsers? The HTML for ContentBody is: <input type="hidden" name="ContentBody" id="ContentBody" value="<%=Model.Article%>" />

  • How do I execute a page-defined JavaScript function from a Firefox extension?

    Hi, I'm creating a Firefox extension for demo purposes. I to call a specific JavaScript function in the document from the extension. I wrote this in my HTML document (not inside extension, but a page that is loaded by Firefox): document.funcToBeCalled = function() { // function body }; Then, the extension will run this on some event: var document = Application.activeWindow.activeTab.document; document.funcToBeCalled(); However it raises an error saying that funcToBeCalled is not defined. Note: I could get an element on the document by calling document.getElementById(id);

  • iphone instance / class method issue

    - by user290031
    Hey All, Okay, so I have a viewController method that has some elements created with interface builder and some I coded myself. I created a view in the IB...lets call it viewOne. I created a loop that creates buttons (through code) and places them on a separate view (viewTwo). This is done in a class method. However, I want the view I made to be opened everytime one of the buttons is clicked. So I did: [button addTarget:self action:@selector(woogoo:) forControlEvents:UIControlEventTouchUpInside]; The woogoo class does the following: +(void) woogoo:(id)sender { //back button [self.view addSubview:viewOne] } However, the program crashes when a button is clicked. I did try making woogoo an instance method but it also crashes in this case too. All I want to do is show viewOne when a button is clicked. Any ideas what I can do?

  • Why is autorelease especially dangerous/expensive for iPhone applications?

    - by e.James
    I'm looking for a primary source (or a really good explanation) to back up the claim that the use of autorelease is dangerous or overly expensive when writing software for the iPhone. Several developers make this claim, and I have even heard that Apple does not recommend it, but I have not been able to turn up any concrete sources to back it up. SO references: autorelease-iphone Why does this create a memory leak (iPhone)? Note: I can see, from a conceptual point of view, that autorelease is slightly more expensive than a simple call to release, but I don't think that small penalty is enough to make Apple recommend against it. What's the real story?

  • Laravel 4 - Using multiple paginators on one page

    - by Fry Farnsworth
    I've been googling for this question but can't find any good answers. I found that there is a method called setPageName() for the paginator but it only works when used like Paginator::setPageName('page'). I looked up the paginator in the Laravel API (http://laravel.com/api/class-Illuminate.Pagination.Environment.html) and the method is a public function just like setBaseUrl which I am currently using like $albums->setBaseUrl('/album/'); for instance I want to have a Photo paginator (?photoPage=n) and a Comment paginator (?commentPage=n). Is there any way that I can use two paginators that use different page names in the URL on one page, or at least call the setPageName() method like setBaseUrl()?
