• Wordpress Iphone App: nsxmlparsererrordomain error 64

  - by iMayne

  Spending hours fixing my function.php page and all seemed well, except Im getting errors on my rss feed at: blog.xternalit.co.uk. I leave that issue to rest and installed wordpress iphone app. The connection to my blog works perfect with wordpress' default theme. Ha! But it keeps making me resetting my password. So hell with that. Switched back to my theme and I cant connect from app to blog. The internet say there's n issue with my function.php. here's a look again at the script: '', 'after_widget' = '', 'before_title' = '', 'after_title' = '', )); function content($num) { $theContent = get_the_content(); $output = preg_replace('/]+./','', $theContent); $limit = $num+1; $content = explode(' ', $output, $limit); array_pop($content); $content = implode(" ",$content)."..."; echo $content; } function post_is_in_descendant_category( $cats, $_post = null ) { foreach ( (array) $cats as $cat ) { // get_term_children() accepts integer ID only $descendants = get_term_children( (int) $cat, 'category'); if ( $descendants && in_category( $descendants, $_post ) ) return true; } return false; } //custom comments function mytheme_comment($comment, $args, $depth) { $GLOBALS['comment'] = $comment; ? id="li-comment-" " %s says:'), get_comment_author_link()) ? comment_approved == '0') : ? $depth, 'max_depth' = $args['max_depth']))) ? </div> 0 && isset($_POST['rockwell_settings']) ) { $options = array ( 'style','logo_img','logo_alt','logo_txt', 'logo_tagline', 'tagline_width', 'contact_email','ads', 'advertise_page', 'twitter_link', 'facebook_link', 'flickr', 'about_tit', 'about_txt', 'analytics'); foreach ( $options as $opt ) { delete_option ( 'rockwell_'.$opt, $_POST[$opt] ); add_option ( 'rockwell_'.$opt, $_POST[$opt] ); } } add_theme_page(__('Rockwell Options'), __('Rockwell Options'), 'edit_themes', basename(__FILE__), 'rockwell_settings'); } function rockwell_settings () {?

• reading Twitter API with JSON framework

  - by iPixFolio

  Hi, I'm building a twitter reader into an app. I'm using this JSON library to parse the twitter API. I'm seeing some odd results on certain messages. I know that the Twitter API returns results in UTF8 format. I'm wondering if I'm doing something wrong when reading the JSON parsed fields. My code is spread out across multiple classes so it's hard to give a concise code drop with the symptoms, but here's what I've got: I am using ASIHTTP for async HTTP processing. Here is processing a response from ASIHTTP: ... NSMutableString* tempString = [[NSMutableString alloc] initWithString:[request responseString]]; NSError *error; SBJSON *json = [[SBJSON alloc] init]; id JSONresponse = [json objectWithString:tempString error:&error]; [tempString release]; [json release]; if (JSONresponse) { self.response = JSONresponse; ... self.response holds the JSON representation of the result from the Twitter call. Now, I will take the JSON response and write each tweet into a container object (Tweet). in the following code, the response from above is referenced as request.response: ... // save list of albums to local cache for (NSDictionary* response in request.response) { Tweet* tweet = [[Tweet alloc] init]; tweet.text = [response objectForKey:@"text"]; tweet.id = [response objectForKey:@"id"]; tweet.created = [response objectForKey:@"created_at"]; [Tweet addTweet:tweet]; [tweet release]; } ... at this point, I have a container holding the tweets. I'm only keeping 3 fields from the tweet: "id", "text", and "created_at". the "text" field is the problem field. To display the tweets, I build an HTML page from the container of tweets, like this: ... Tweet* tweet = nil; for (int i = 0; i < [Tweet tweetCount]; i++) { tweet = [Tweet tweetAtIndex:i]; [html appendString:@"<div class='tweet'>"]; [html appendFormat:@"<div class='tweet-date'>%@</div>", tweet.created ]; [html appendFormat:@"<div class='tweet-text'>%@</div>", tweet.text ]; [html appendString:@"</div>"]; } ... In another routine, I save the HTML page to a temp file. if (html && [html length] > 0 ) { NSString* uniqueString = [[NSProcessInfo processInfo] globallyUniqueString]; NSString* filename = [NSString stringWithFormat:@"%@.html", uniqueString ]; filename = [tempDir stringByAppendingPathComponent:filename]; NSError* error = nil; [html writeToFile:filename atomically:NO encoding:NSUTF8StringEncoding error:&error]; ... I then create a URLRequest from the file and load it into an UIWebview: NSURL* url = [NSURL fileURLWithPath:filename]; NSURLRequest* request = [NSURLRequest requestWithURL:url]; [self.webView loadRequest:request]; ... At this point, I can see the tweets in a browser window. some of the tweets will show invalid characters like this: iPhone 4 ad spoofed with Glee’s Jane Lynch ... Glee’s should be Glee's Can anybody shed any light on what I'm doing wrong and offer suggestions on how to fix? basically, to summarize: I'm reading a UTF8 feed with JSON I write the UTF8 strings into an HTML file I display the HTML file with UIWebview. some of the UTF8 strings are not properly decoded. I need to know where to decode them and how to do it. thanks! Mark

• Domain Validation in a CQRS architecture

  - by Jupaol

  Basically I want to know if there is a better way to validate my domain entities. This is how I am planning to do it but I would like your opinion The first approach I considered was: class Customer : EntityBase<Customer> { public void ChangeEmail(string email) { if(string.IsNullOrWhitespace(email)) throw new DomainException(“...”); if(!email.IsEmail()) throw new DomainException(); if(email.Contains(“@mailinator.com”)) throw new DomainException(); } } I actually do not like this validation because even when I am encapsulating the validation logic in the correct entity, this is violating the Open/Close principle (Open for extension but Close for modification) and I have found that violating this principle, code maintenance becomes a real pain when the application grows up in complexity. Why? Because domain rules change more often than we would like to admit, and if the rules are hidden and embedded in an entity like this, they are hard to test, hard to read, hard to maintain but the real reason why I do not like this approach is: if the validation rules change, I have to come and edit my domain entity. This has been a really simple example but in RL the validation could be more complex So following the philosophy of Udi Dahan, making roles explicit, and the recommendation from Eric Evans in the blue book, the next try was to implement the specification pattern, something like this class EmailDomainIsAllowedSpecification : IDomainSpecification<Customer> { private INotAllowedEmailDomainsResolver invalidEmailDomainsResolver; public bool IsSatisfiedBy(Customer customer) { return !this.invalidEmailDomainsResolver.GetInvalidEmailDomains().Contains(customer.Email); } } But then I realize that in order to follow this approach I had to mutate my entities first in order to pass the value being valdiated, in this case the email, but mutating them would cause my domain events being fired which I wouldn’t like to happen until the new email is valid So after considering these approaches, I came out with this one, since I am going to implement a CQRS architecture: class EmailDomainIsAllowedValidator : IDomainInvariantValidator<Customer, ChangeEmailCommand> { public void IsValid(Customer entity, ChangeEmailCommand command) { if(!command.Email.HasValidDomain()) throw new DomainException(“...”); } } Well that’s the main idea, the entity is passed to the validator in case we need some value from the entity to perform the validation, the command contains the data coming from the user and since the validators are considered injectable objects they could have external dependencies injected if the validation requires it. Now the dilemma, I am happy with a design like this because my validation is encapsulated in individual objects which brings many advantages: easy unit test, easy to maintain, domain invariants are explicitly expressed using the Ubiquitous Language, easy to extend, validation logic is centralized and validators can be used together to enforce complex domain rules. And even when I know I am placing the validation of my entities outside of them (You could argue a code smell - Anemic Domain) but I think the trade-off is acceptable But there is one thing that I have not figured out how to implement it in a clean way. How should I use this components... Since they will be injected, they won’t fit naturally inside my domain entities, so basically I see two options: Pass the validators to each method of my entity Validate my objects externally (from the command handler) I am not happy with the option 1 so I would explain how I would do it with the option 2 class ChangeEmailCommandHandler : ICommandHandler<ChangeEmailCommand> { public void Execute(ChangeEmailCommand command) { private IEnumerable<IDomainInvariantValidator> validators; // here I would get the validators required for this command injected, and in here I would validate them, something like this using (var t = this.unitOfWork.BeginTransaction()) { var customer = this.unitOfWork.Get<Customer>(command.CustomerId); this.validators.ForEach(x =. x.IsValid(customer, command)); // here I know the command is valid // the call to ChangeEmail will fire domain events as needed customer.ChangeEmail(command.Email); t.Commit(); } } } Well this is it. Can you give me your thoughts about this or share your experiences with Domain entities validation EDIT I think it is not clear from my question, but the real problem is: Hiding the domain rules has serious implications in the future maintainability of the application, and also domain rules change often during the life-cycle of the app. Hence implementing them with this in mind would let us extend them easily. Now imagine in the future a rules engine is implemented, if the rules are encapsulated outside of the domain entities, this change would be easier to implement

• MVC keeping the PartialView in its own context - ignore the main view holding the partial view

  - by Mike

  I'm looking at the partialview components of the MVC Framework. i want my partial view to be handled in its own action and for the rest of the view to handle itself, but i'm getting an exception because the main page is not getting its view fired. Am i going around this the wrong way? My Main View (Jobs/Index.aspx): <%@ Page Title="" Language="C#" MasterPageFile="~/Views/Shared/Site.Master" Inherits="System.Web.Mvc.ViewPage<MvcApplication3.Models.JobViewModel>" %> <asp:Content ID="Content2" ContentPlaceHolderID="MainContent" runat="server"> <% Html.RenderPartial("JobListing", Model.Jobs); %> </asp:Content> The partialview (Jobs/JobListing.ascx): <%@ Control Language="C#" Inherits="System.Web.Mvc.ViewUserControl<List<MvcApplication3.Models.Job>>" %> <table> <tr> <td> Job Title </td> <td> Job Location</td> </tr> <% foreach (var job in Model) { %> <tr> <td> <%= job.Title %> </td> <td> <%= job.Location %> </td> </tr> <% } %> <% Html.BeginForm("DoSomeStuff", "Job", null, FormMethod.Post); %> <%= Html.TextBox("SomeInfo") %> <button type="submit" id="submit" /> <% Html.EndForm(); %> The main controller for both the main view (Index) and the partialview (DoSomeStuff()) public class JobController : Controller { public ActionResult Index() { JobProvider provider = new JobProvider(Session); JobViewModel vm = new JobViewModel(); vm.Jobs = provider.GetJobs(); return View(vm); } public PartialViewResult DoSomeStuff() { return PartialView("JobListing"); } } As you can see in the partial view, it has its own form that posts to the Action called DoSomeStuff(). i want this action to handle any data submitted from that form. but when the form is submitted the main action (Index) does not fire and then i get an exception as the Model (.Models.JobViewModel) is not passed to the view that the partialview (JobListings) lives in. basically what im saying is, if i have a myview.aspx with lots of html.RenderPartialView('apartialview') that have forms in them, can i get it so these forms post to their own actions and the main view (with what ever model it inherits) is handled as well. Rather then having all the form submitting code in the main action for the view. am i do this wrong?

• Rx IObservable buffering to smooth out bursts of events

  - by Dan

  I have an Observable sequence that produces events in rapid bursts (ie: five events one right after another, then a long delay, then another quick burst of events, etc.). I want to smooth out these bursts by inserting a short delay between events. Imagine the following diagram as an example: Raw: --oooo--------------ooooo-----oo----------------ooo| Buffered: --o--o--o--o--------o--o--o--o--o--o--o---------o--o--o| My current approach is to generate a metronome-like timer via Observable.Interval() that signals when it's ok to pull another event from the raw stream. The problem is that I can't figure out how to then combine that timer with my raw unbuffered observable sequence. IObservable.Zip() is close to doing what I want, but it only works so long as the raw stream is producing events faster than the timer. As soon as there is a significant lull in the raw stream, the timer builds up a series of unwanted events that then immediately pair up with the next burst of events from the raw stream. Ideally, I want an IObservable extension method with the following function signature that produces the bevaior I've outlined above. Now, come to my rescue StackOverflow :) public static IObservable<T> Buffered(this IObservable<T> src, TimeSpan minDelay) PS. I'm brand new to Rx, so my apologies if this is a trivially simple question... 1. Simple yet flawed approach Here's my initial naive and simplistic solution that has quite a few problems: public static IObservable<T> Buffered<T>(this IObservable<T> source, TimeSpan minDelay) { Queue<T> q = new Queue<T>(); source.Subscribe(x => q.Enqueue(x)); return Observable.Interval(minDelay).Where(_ => q.Count > 0).Select(_ => q.Dequeue()); } The first obvious problem with this is that the IDisposable returned by the inner subscription to the raw source is lost and therefore the subscription can't be terminated. Calling Dispose on the IDisposable returned by this method kills the timer, but not the underlying raw event feed that is now needlessly filling the queue with nobody left to pull events from the queue. The second problem is that there's no way for exceptions or end-of-stream notifications to be propogated through from the raw event stream to the buffered stream - they are simply ignored when subscribing to the raw source. And last but not least, now I've got code that wakes up periodically regardless of whether there is actually any work to do, which I'd prefer to avoid in this wonderful new reactive world. 2. Way overly complex appoach To solve the problems encountered in my initial simplistic approach, I wrote a much more complicated function that behaves much like IObservable.Delay() (I used .NET Reflector to read that code and used it as the basis of my function). Unfortunately, a lot of the boilerplate logic such as AnonymousObservable is not publicly accessible outside the system.reactive code, so I had to copy and paste a lot of code. This solution appears to work, but given its complexity, I'm less confident that its bug free. I just can't believe that there isn't a way to accomplish this using some combination of the standard Reactive extensions. I hate feeling like I'm needlessly reinventing the wheel, and the pattern I'm trying to build seems like a fairly standard one.

  Hi all I read http://forum.kohanaframework.org/comments.php?DiscussionID=5744&page=1#Item_0 and I want to use similar solution, but with db.

• Error data: line 2 column 1 when using pycurl with gzip stream

  - by Sagar Hatekar

  Thanks for reading. Background: I am trying to read a streaming API feed that returns data in JSON format, and then storing this data to a pymongo collection. The streaming API requires a "Accept-Encoding" : "Gzip" header. What's happening: Code fails on json.loads and outputs - Extra data: line 2 column 1 - line 4 column 1 (char 1891 - 5597) (Refer Error Log below) This does NOT happen while parsing every JSON object - it happens at random. My guess is I am encountering some weird JSON object after every "x" proper JSON objects. I did reference how to use pycurl if requested data is sometimes gzipped, sometimes not? and Encoding error while deserializing a json object from Google but so far have been unsuccessful at resolving this error. Could someone please help me out here? Error Log: Note: The raw dump of the JSON object below is basically using the repr() method.

• How can I make this Java code run faster?

  Hello all, I am trying to make a Java port of a simple feed-forward neural network. This obviously involves lots of numeric calculations, so I am trying to optimize my central loop as much as possible. The results should be correct within the limits of the float data type. My current code looks as follows (error handling & initialization removed): /** * Simple implementation of a feedforward neural network. The network supports * including a bias neuron with a constant output of 1.0 and weighted synapses * to hidden and output layers. * * @author Martin Wiboe */ public class FeedForwardNetwork { private final int outputNeurons; // No of neurons in output layer private final int inputNeurons; // No of neurons in input layer private int largestLayerNeurons; // No of neurons in largest layer private final int numberLayers; // No of layers private final int[] neuronCounts; // Neuron count in each layer, 0 is input // layer. private final float[][][] fWeights; // Weights between neurons. // fWeight[fromLayer][fromNeuron][toNeuron] // is the weight from fromNeuron in // fromLayer to toNeuron in layer // fromLayer+1. private float[][] neuronOutput; // Temporary storage of output from previous layer public float[] compute(float[] input) { // Copy input values to input layer output for (int i = 0; i < inputNeurons; i++) { neuronOutput[0][i] = input[i]; } // Loop through layers for (int layer = 1; layer < numberLayers; layer++) { // Loop over neurons in the layer and determine weighted input sum for (int neuron = 0; neuron < neuronCounts[layer]; neuron++) { // Bias neuron is the last neuron in the previous layer int biasNeuron = neuronCounts[layer - 1]; // Get weighted input from bias neuron - output is always 1.0 float activation = 1.0F * fWeights[layer - 1][biasNeuron][neuron]; // Get weighted inputs from rest of neurons in previous layer for (int inputNeuron = 0; inputNeuron < biasNeuron; inputNeuron++) { activation += neuronOutput[layer-1][inputNeuron] * fWeights[layer - 1][inputNeuron][neuron]; } // Store neuron output for next round of computation neuronOutput[layer][neuron] = sigmoid(activation); } } // Return output from network = output from last layer float[] result = new float[outputNeurons]; for (int i = 0; i < outputNeurons; i++) result[i] = neuronOutput[numberLayers - 1][i]; return result; } private final static float sigmoid(final float input) { return (float) (1.0F / (1.0F + Math.exp(-1.0F * input))); } } I am running the JVM with the -server option, and as of now my code is between 25% and 50% slower than similar C code. What can I do to improve this situation? Thank you, Martin Wiboe

• How can I turn a SimpleXML object to array, then shuffle?

  - by Joshua Cody

  Crux of my problem: I've got an XML file that returns 20 results. Within these results are all the elements I need to get. Now, I need to return them in a random order, and be able to specifically work with item 1, items 2-5, and items 6-17. Idea 1: Use this script to convert the object to an array, which I can shuffle through. This is close to working, but a few of the elements I need to get are under a different namespace, and I don't seem to be able to get them. Code: /* * Convert a SimpleXML object into an array (last resort). * * @access public * @param object $xml * @param boolean $root - Should we append the root node into the array * @return array */ function xmlToArray($xml, $root = true) { if (!$xml->children()) { return (string)$xml; } $array = array(); foreach ($xml->children() as $element => $node) { $totalElement = count($xml->{$element}); if (!isset($array[$element])) { $array[$element] = ""; } // Has attributes if ($attributes = $node->attributes()) { $data = array( 'attributes' => array(), 'value' => (count($node) > 0) ? xmlToArray($node, false) : (string)$node // 'value' => (string)$node (old code) ); foreach ($attributes as $attr => $value) { $data['attributes'][$attr] = (string)$value; } if ($totalElement > 1) { $array[$element][] = $data; } else { $array[$element] = $data; } // Just a value } else { if ($totalElement > 1) { $array[$element][] = xmlToArray($node, false); } else { $array[$element] = xmlToArray($node, false); } } } if ($root) { return array($xml->getName() => $array); } else { return $array; } } $thumbfeed = simplexml_load_file('http://gdata.youtube.com/feeds/api/videos?q=skadaddlemedia&max-results=20&orderby=published&prettyprint=true'); $xmlToArray = xmlToArray($thumbfeed); $thumbArray = $xmlToArray["feed"]; for($n = 0; $n < 18; $n++){ $title = $thumbArray["entry"][$n]["title"]["value"]; $desc = $thumbArray["entry"][0]["content"]["value"]; $videoUrl = $differentNamespace; $thumbUrl = $differentNamespace; } Idea 2: Continue using my working code that is getting the information using a foreach, but store each element in an array, then use shuffle on that. I'm not precisely sure hwo to write to an array within a foreach loop and not write over one another, though. Working code: foreach($thumbfeed->entry as $entry){ $thumbmedia = $entry->children('http://search.yahoo.com/mrss/') ->group ; $thumb = $thumbmedia->thumbnail[0]->attributes()->url; $thumburl = $thumbmedia->content[0]->attributes()->url; $thumburl1 = explode("http://www.youtube.com/v/", $thumburl[0]); $thumbid = explode("?f=videos&app=youtube_gdata", $thumburl1[1]); $thumbtitle = $thumbmedia->title; $thumbyt = $thumbmedia->children('http://gdata.youtube.com/schemas/2007') ->duration ; $thumblength = $thumbyt->attributes()->seconds; } Ideas on if either of these are good solutions to my problem, and if so, how I can get over my execution humps? Thanks so much for any help you can give.

• Why does this valid Tkinter code crash when mixed with a bit of PyWin32?

  - by Erlog

  So I'm making a very small program for personal use in tkinter, and I've run into a really strange wall. I'm mixing tkinter with the pywin32 bindings because I really hate everything to do with the syntax and naming conventions of pywin32, and it feels like tkinter gets more done with far less code. The strangeness is happening in the transition between the pywin32 clipboard watching and my program's reaction to it in tkinter. My window and all its controls are being handled in tkinter. The pywin32 bindings are doing clipboard watching and clipboard access when the clipboard changes. From what I've gathered about the way the clipboard watching pieces of pywin32 work, you can make it work with anything you want as long as you provide pywin32 with the hwnd value of your window. I'm doing that part, and it works when the program first starts. It just doesn't seem to work when the clipboard changes. When the program launches, it grabs the clipboard and puts it into the search box and edit box just fine. When the clipboard is modified, the event I want to fire off is firing off...except that event that totally worked before when the program launched is now causing a weird hang instead of doing what it's supposed to do. I can print the clipboard contents to stdout all I want if the clipboard changes, but not put that same data into a tkinter widget. It only hangs like that if it starts to interact with any of my tkinter widgets after being fired off by a clipboard change notification. It feels like there's some pywin32 etiquette I've missed in adapting the clipboard-watching sample code I was using over to my tkinter-using program. Tkinter apparently doesn't like to produce stack traces or error messages, and I can't really even begin to know what to look for trying to debug it with pdb. Here's the code: #coding: utf-8 #Clipboard watching cribbed from ## {{{ http://code.activestate.com/recipes/355593/ (r1) import pdb from Tkinter import * import win32clipboard import win32api import win32gui import win32con import win32clipboard def force_unicode(object, encoding="utf-8"): if isinstance(object, basestring) and not isinstance(object, unicode): object = unicode(object, encoding) return object class Application(Frame): def __init__(self, master=None): self.master = master Frame.__init__(self, master) self.pack() self.createWidgets() self.hwnd = self.winfo_id() self.nextWnd = None self.first = True self.oldWndProc = win32gui.SetWindowLong(self.hwnd, win32con.GWL_WNDPROC, self.MyWndProc) try: self.nextWnd = win32clipboard.SetClipboardViewer(self.hwnd) except win32api.error: if win32api.GetLastError () == 0: # information that there is no other window in chain pass else: raise self.update_search_box() self.word_search() def word_search(self): #pdb.set_trace() term = self.searchbox.get() self.resultsbox.insert(END, term) def update_search_box(self): clipboardtext = "" if win32clipboard.IsClipboardFormatAvailable(win32clipboard.CF_TEXT): win32clipboard.OpenClipboard() clipboardtext = win32clipboard.GetClipboardData() win32clipboard.CloseClipboard() if clipboardtext != "": self.searchbox.delete(0,END) clipboardtext = force_unicode(clipboardtext) self.searchbox.insert(0, clipboardtext) def createWidgets(self): self.button = Button(self) self.button["text"] = "Search" self.button["command"] = self.word_search self.searchbox = Entry(self) self.resultsbox = Text(self) #Pack everything down here for "easy" layout changes later self.searchbox.pack() self.button.pack() self.resultsbox.pack() def MyWndProc (self, hWnd, msg, wParam, lParam): if msg == win32con.WM_CHANGECBCHAIN: self.OnChangeCBChain(msg, wParam, lParam) elif msg == win32con.WM_DRAWCLIPBOARD: self.OnDrawClipboard(msg, wParam, lParam) # Restore the old WndProc.

• UIView, UIScrollView and UITextFields problem calling Method

  - by Jeff Groby

  I have a view with several embedded UITextFields, this UIView is subordinated to a UIScrollView in IB. Each text field is supposed to invoke a method called updateText defined in the viewcontroller implementation file when the user is done editing the field. For some reason, the method updateText never gets invoked. Anyone have any ideas how to go about fixing this? The method fired off just fine when the UIScrollView was not present in the project but the keyboard would cover the text fields during input, which was annoying. Now my textfields move up above the keyboard when it appears, but won't fire off the method when done editing. Here is my implementation file: #import "MileMarkerViewController.h" @implementation MileMarkerViewController @synthesize scrollView,milemarkerLogDate,milemarkerDesc,milemarkerOdobeg,milemarkerOdoend,milemarkerBusiness,milemarkerPersonal,milemarker; - (id)initWithNibName:(NSString *)nibNameOrNil bundle:(NSBundle *)nibBundleOrNil { if (self = [super initWithNibName:nibNameOrNil bundle:nibBundleOrNil]) { // Initialization code } return self; } - (BOOL) textFieldShouldReturn: (UITextField*) theTextField { return [theTextField resignFirstResponder]; } - (void)viewDidLoad { [super viewDidLoad]; [[NSNotificationCenter defaultCenter] addObserver: self selector: @selector(keyboardWasShown:) name: UIKeyboardDidShowNotification object: nil]; [[NSNotificationCenter defaultCenter] addObserver: self selector: @selector(keyboardWasHidden:) name: UIKeyboardDidHideNotification object: nil]; keyboardShown = NO; // 1 [scrollView setContentSize: CGSizeMake( 320, 480)]; // 2 } - (void)keyboardWasShown:(NSNotification*)aNotification { if (keyboardShown) return; NSDictionary* info = [aNotification userInfo]; // Get the size of the keyboard.

• Need help with memory leaks in RSS Reader

  - by Stilton

  I'm trying to write a simple RSS reader for the iPhone, and it appeared to be working fine, until I started working with Instruments, and discovered my App is leaking massive amounts of memory. I'm using the NSXMLParser class to parse an RSS feed. My memory leaks appear to be originating from the overridden delegate methods: - (void)parser:(NSXMLParser *)parser foundCharacters:(NSString *)string and - (void)parser:(NSXMLParser *)parser didEndElement:(NSString *)elementName namespaceURI:(NSString *)namespaceURI qualifiedName:(NSString *)qName I'm also suspicious of the code that populates the cells from my parsed data, I've included the code from those methods and a few other key ones, any insights would be greatly appreciated. - (void)parser:(NSXMLParser *)parser foundCharacters:(NSString *)string { if ([self.currentElement isEqualToString:@"title"]) { [self.currentTitle appendString:string]; } else if ([self.currentElement isEqualToString:@"link"]) { [self.currentURL appendString:string]; } else if ([self.currentElement isEqualToString:@"description"]) { [self.currentSummary appendString:string]; } } - (void)parser:(NSXMLParser *)parser didEndElement:(NSString *)elementName namespaceURI:(NSString *)namespaceURI qualifiedName:(NSString *)qName { if ([elementName isEqualToString:@"item"]) { //asdf NSMutableDictionary *item = [[NSMutableDictionary alloc] init]; [item setObject:currentTitle forKey:@"title"]; [item setObject:currentURL forKey:@"URL"]; [item setObject:currentSummary forKey:@"summary"]; [self.currentTitle release]; [self.currentURL release]; [self.currentSummary release]; [self.stories addObject:item]; [item release]; } } // Customize the appearance of table view cells. - (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath { static NSString *CellIdentifier = @"Cell"; UITableViewCell *cell = [tableView dequeueReusableCellWithIdentifier:CellIdentifier]; if (cell == nil) { cell = [[[UITableViewCell alloc] initWithStyle:UITableViewCellStyleDefault reuseIdentifier:CellIdentifier] autorelease]; } // Configure the cell. // Set up the cell int index = [indexPath indexAtPosition: [indexPath length] - 1]; CGRect contentRect = CGRectMake(8.0, 4.0, 260, 20); UILabel *textLabel = [[UILabel alloc] initWithFrame:contentRect]; if (self.currentLevel == 0) { textLabel.text = [self.categories objectAtIndex: index]; } else { textLabel.text = [[self.stories objectAtIndex: index] objectForKey:@"title"]; } textLabel.textColor = [UIColor blackColor]; textLabel.font = [UIFont boldSystemFontOfSize:14]; [[cell contentView] addSubview: textLabel]; //[cell setText:[[stories objectAtIndex: storyIndex] objectForKey: @"title"]]; [textLabel autorelease]; return cell; } - (void)parser:(NSXMLParser *)parser didStartElement:(NSString *)elementName namespaceURI:(NSString *)namespaceURI qualifiedName:(NSString *)qName attributes:(NSDictionary *)attributeDict { if ([elementName isEqualToString:@"item"]) { self.currentTitle = [[NSMutableString alloc] init]; self.currentURL = [[NSMutableString alloc] init]; self.currentSummary = [[NSMutableString alloc] init]; } if (currentElement != nil) { [self.currentElement release]; } self.currentElement = [elementName copy]; } - (void)dealloc { [currentElement release]; [currentTitle release]; [currentURL release]; [currentSummary release]; [currentDate release]; [stories release]; [rssParser release]; [storyTable release]; [super dealloc]; } // Override to support row selection in the table view. - (void)tableView:(UITableView *)tableView didSelectRowAtIndexPath:(NSIndexPath *)indexPath { // Navigation logic may go here -- for example, create and push another view controller. // AnotherViewController *anotherViewController = [[AnotherViewController alloc] initWithNibName:@"AnotherView" bundle:nil]; int index = [indexPath indexAtPosition: [indexPath length] - 1]; if (currentLevel == 1) { StoryViewController *storyViewController = [[StoryViewController alloc] initWithURL:[[stories objectAtIndex: index] objectForKey:@"URL"] nibName:@"StoryViewController" bundle:nil]; [self.navigationController pushViewController:storyViewController animated:YES]; [storyViewController release]; } else { RootViewController *rvController = [[RootViewController alloc] initWithNibName:@"RootViewController" bundle:nil]; rvController.currentLevel = currentLevel + 1; rvController.rssIndex = index; [self.navigationController pushViewController:rvController animated:YES]; [rvController release]; } }

• Ado.net Fill method not throwing error on running a Stored Procedure that does not exist.

  - by Mike

  I am using a combination of the Enterprise library and the original Fill method of ADO. This is because I need to open and close the command connection myself as I am capture the event Info Message Here is my code so far // Set Up Command SqlDatabase db = new SqlDatabase(ConfigurationManager.ConnectionStrings[ConnectionName].ConnectionString); SqlCommand command = db.GetStoredProcCommand(StoredProcName) as SqlCommand; command.Connection = db.CreateConnection() as SqlConnection; // Set Up Events for Logging command.StatementCompleted += new StatementCompletedEventHandler(command_StatementCompleted); command.Connection.FireInfoMessageEventOnUserErrors = true; command.Connection.InfoMessage += new SqlInfoMessageEventHandler(Connection_InfoMessage); // Add Parameters foreach (Parameter parameter in Parameters) { db.AddInParameter(command, parameter.Name, (System.Data.DbType)Enum.Parse(typeof(System.Data.DbType), parameter.Type), parameter.Value); } // Use the Old Style fill to keep the connection Open througout the population // and manage the Statement Complete and InfoMessage events SqlDataAdapter da = new SqlDataAdapter(command); DataSet ds = new DataSet(); // Open Connection command.Connection.Open(); // Populate da.Fill(ds); // Dispose of the adapter if (da != null) { da.Dispose(); } // If you do not explicitly close the connection here, it will leak! if (command.Connection.State == ConnectionState.Open) { command.Connection.Close(); } ... Now if I pass into the variable StoredProcName = "ThisProcDoesNotExists" And run this peice of code. The CreateCommand nor da.Fill through an error message. Why is this. The only way I can tell it did not run was that it returns a dataset with 0 tables in it. But when investigating the error it is not appearant that the procedure does not exist. EDIT Upon further investigation command.Connection.FireInfoMessageEventOnUserErrors = true; is causeing the error to be surpressed into the InfoMessage Event From BOL When you set FireInfoMessageEventOnUserErrors to true, errors that were previously treated as exceptions are now handled as InfoMessage events. All events fire immediately and are handled by the event handler. If is FireInfoMessageEventOnUserErrors is set to false, then InfoMessage events are handled at the end of the procedure. What I want is each print statement from Sql to create a new log record. Setting this property to false combines it as one big string. So if I leave the property set to true, now the question is can I discern a print message from an Error ANOTHER EDIT So now I have the code so that the flag is set to true and checking the error number in the method void Connection_InfoMessage(object sender, SqlInfoMessageEventArgs e) { // These are not really errors unless the Number >0 // if Number = 0 that is a print message foreach (SqlError sql in e.Errors) { if (sql.Number == 0) { Logger.WriteInfo("Sql Message",sql.Message); } else { // Whatever this was it was an error throw new DataException(String.Format("Message={0},Line={1},Number={2},State{3}", sql.Message, sql.LineNumber, sql.Number, sql.State)); } } } The issue now that when I throw the error it does not bubble up to the statement that made the call or even the error handler that is above that. It just bombs out on that line The populate looks like // Populate try { da.Fill(ds); } catch (Exception e) { throw new Exception(e.Message, e); } Now even though I see the calling codes and methods still in the Call Stack, this exception does not seem to bubble up?

• Editing a Gridview row with drop-down lists gets too wide - how can I use popup panels instead?

  - by David

  I have a series of GridViews in a Tab Panel - databound to a generic List of Business Objects. The columns in the Gridview are all similar to the following: <asp:TemplateField HeaderText="Company" SortExpression="Company.ShortName"> <ItemTemplate> <asp:Label ID="lblCompany" runat="server" Text='<%# Bind("Company.ShortName") %>'></asp:Label> </ItemTemplate> <EditItemTemplate> <asp:DropDownList ID="ddlCompany" runat="server"></asp:DropDownList> </EditItemTemplate> </asp:TemplateField> The GridView generates the "Edit" link at the beginning of the row, all the events fire ok. The problem is that the data is getting long. When in 'display mode', it's fine because the GridView control is smart enough to break some text into multiple lines (in particular Project, Title and Worker names can get pretty long). The problem come in editing mode. Drop-down lists DON'T break entries into multiple lines (for obvious reasons). Going into Edit ode on a row in the Gridview can make the Griview expand horizontally to twice the screen size (blowing through the width limits in the Master page and CSS but that's only a related problem). What I need is something like the ModalPopup - but trying to tie it to an ID in an EditItemTemplate gives me errors when the page renders (because the 'ddlXXXX' doesn't exist at the time). In addition I don't know how to dynamically populate the panel so that I can get a response from it (like the ID of the Company they selected). I'm also trying to avoid javascript and would like this to be a 'pure' aspx/code-behind solution (for simplicity's sake among others). All the examples I find are of Modal Popups with the panels pre-defined. Even if it (the popup panel) were something like a list of checkboxes, it could be databound to the SortedList I have ready to go and an OK/Cancel button combination to accept or ignore things. I'm just not sure of what goes where. I'm open to suggestions. Thanks in advance. EDIT: Final solution looks as follows: <asp:TemplateField HeaderText="Company" SortExpression="Company.ShortName"> <ItemTemplate> <asp:Label ID="lblCompany" runat="server" Text='<%# Bind("Company.ShortName") %>'></asp:Label> </ItemTemplate> <EditItemTemplate> <asp:LinkButton ID="lnkCompany" runat="server" Text='<%# Bind("Company.ShortName") %>'></asp:LinkButton> <asp:Panel ID="pnlCompany" runat="server" style="display:none"> <div> <asp:DropDownList ID="ddlCompany" runat="server" ></asp:DropDownList> <br/> <asp:ImageButton ID="btnOKCo" runat="server" ImageUrl="~/Images/greencheck.gif" OnCommand="PopupButton_Command" CommandName="SelectCO" /> <asp:ImageButton ID="btnCxlCo" runat="server" ImageUrl="~/Images/RedX.gif" /> </div> </asp:Panel> <cc1:ModalPopupExtender ID="mpeCompany" runat="server" TargetControlID="lnkCompany" PopupControlID="pnlCompany" BackgroundCssClass="modalBackground" CancelControlID="btnCxlCo" DropShadow="true" PopupDragHandleControlID="pnlCompany" /> </EditItemTemplate> </asp:TemplateField> And in the code-behind, lstIDLabor is the generic List of data lines (of which Company is one of the properties that is also a business object) that is bound to the GridView: Sub PopupButton_Command(ByVal sender As Object, ByVal e As CommandEventArgs) Dim intRow As Integer Dim intVal As Integer RestoreFromSessionVariables() Select Case e.CommandName Case "SelectCO" intRow = grdIDCostLabor.EditIndex Dim ddlCo As DropDownList = CType(grdIDCost.Rows(intRow).FindControl("ddlCompany"), DropDownList) intVal = ddlCo.SelectedValue lstIDLabor(intRow).CompanyID = intVal lstIDLabor(intRow).Company = Company.Read(intVal) Case Else ' End Select MakeSessionVariables() BindGrids() End Sub

• Php template caching design

  - by Thomas

  Hello to all, I want to include caching in my app design. Caching templates for starters. The design I have used so far is very modular. I have created an ORM implementation for all my tables and each table is represented by the corresponding class. All the requests are handled by one controller which routes them to the appropriate webmethod functions. I am using a template class for handling UI parts. What I have in mind for caching includes the implementation of a separate Cache class for handling caching with the flexibility to either store in files, apc or memcache. Right now I am testing with file caching. Some thoughts Should I include the logic of checking for cached versions in the Template class or in the webmethods which handle the incoming requests and which eventually call the Template class. In the first case, things are pretty simple as I will not have to change anything more than pass the template class an extra argument (whether to load from cache or not). In the second case however, I am thinking of checking for a cached version immediately in the webmethod and if found return it. This will save all the processing done until the logic reaches the template (first case senario). Both senarios however, rely on an accurate mechanism of invalidating caches, which brings as to Invalidating caches As I see it (and you can add your input freely) a template cached file, becomes invalidate if: a. the expiration set, is reached. b. the template file itself is updated (ie by the developer when adding a new line) c. the webmethod that handles the request changes (ie the developer adds/deletes something in the code) d. content coming from the db and ending in the template file is modified I am thinking of storing a json encoded array inside the cached file. The first value will be the expiration timestamp of the cache. The second value will be the modification time of the php file with the code handling the request (to cope with option c above) The third will be the content itself The validation process I am considering, according to the above senarios, is: a. If the expiration of the cached file (stored in the array) is reached, delete the cache file b. if the cached file's mod time is smaller than the template's skeleton file mod time, delete the cached file c. if the mod time of the php file is greated than the one stored in the cache, delete the cached file. d. This is tricky. In the ORM implementation I ahve added event handlers (which fire when adding, updating, deleting objects). I could delete the cache file every time an object thatprovides content to the template, is modified. The problem is how to keep track which cached files correpond to each schema object. Take this example, a user has his shortprofile page and a full profile page (2 templates) These templates can be cached. Now, every time the user modifies his profile, the event handler would need to know which templates or cached files correspond to the User, so that these files can be deleted. I could store them in the db but I am looking for a beter approach

• Apache/PHP serving file multiple times

  - by easement

  I have a system with a download.php page. The page takes and id and loads a file based on from the DB Record and then serves it up. I've noticed a couple instances where files are requested multiple times in short time spans (20ms). Times that are too quick for human input. There are plenty of instances where the downloader functions fine. However, in taking a closer look at the downloader’s usage, I did see some interesting behavior. For instance, the IP address xxx.xxx.xxx.xxx (which is one in a range owned by xxxxxx.de in Germany) came to the site through Google. They browsed around and then came to the page http://site.com/xxxx/press+125.php There they issued a request for /download.php?id=/ZZ/n+aH55Y= (a PDF) at 9:04:23AM. That alone is not a big deal. However, what is interesting is that the server seems to have been quite preoccupied with serving that request. In the logs the request first completes between 9:09:48 and 9:10:00. It looks like the user must have gotten tired of waiting during that time and requested the document two more times. Between 09:14:47 and 09:15:00 the same request appears again, except it is from 9:04:43AM, 20ms later than the first request. Then it pops up a third time, with a request that started at 09:05:06 completing between 09:19:55 and 09:19:58! I’m suspicious of that document. In looking through the logs I see other instances where it takes the server a little while to handle that specific file. Check out this list of requests from zzz.zzz.zzz.zzz[different than above] for the file /download.php?id=/ZZ/n+aH55Y= (the same docuemnt as before): Request time Complete Time 04:32:43 04:33:36 04:32:50 04:33:36 04:32:51 04:33:38 04:33:05 04:33:38 04:33:34 04:33:42 04:33:05 04:33:42 So something is definitely going on. Whether it has to do with this specific document tripping up the server, the download.php page’s code, or if we’re just seeing the evidence of some server level overload as it plays out in real time I’m not yet sure. In fairness, there are other instances of people downloading /download.php?id=/ZZ/n+aH55Y= (the same PDF) without error. However, it is interesting that the multiple processes only seem to happen with this one file, and then only when it is accessed through the page http://site.com/press+125.php . It bears further investigation if there’s something amiss inside the code that causes the system to fire off multiple download requests that occupy the server. I don't know if this press+125.php is a rabbit hole, but there is weird consicence. Any ideas? I'm totally out of ideas. Apache maxed out? Things like that. ///DOWNLOAD.php $file = new files(); $file->comparison_filter("id", "=", $id); //sql to load if ($file->load()) { $file->serve(); } //FILES function serve() { if ($this->is_loaded) { if (file_exists($this->get_value("filename"))) { if ($this->get_value("content_type") != "") { header("Content-Type: " . $this->get_value("content_type")); } header("Content-Length: " . filesize($this->get_value("filename"))); if ($this->get_value("flag_image") == 0 || $this->get_value("flag_image") == false) { header("Cache-Control: private"); header("Content-Disposition: attachment; filename=" . urlencode($this->get_value("original_filename"))); } set_time_limit(0); @readfile($this->get_value("filename")); exit; } } }

• window.requestFileSystem fails/events firing multiple times in PhoneGap Cordova 3

  - by ezycheez

  cordova 3.1.0-0.2.0 Droid Razr M Android 4.1.2 Windows 7 New to PhoneGap/Cordova. Running one of the filesystem demos from http://docs.phonegap.com/en/3.1.0/cordova_file_file.md.html#File. Using "cordova run android" to compile the code and run it on the phone attached via USB. Problem #1: When the app first starts I get alert("1") twice and then nothing else. Problem #2: When I kick of the code via the button onclick I get the following alert pattern: 1, 2, 2, 3, 3, 4, 6, 5, 7, 4, 6, 5, 7. Some of that makes sense based on the code flow but most of them are firing twice. I'm suspecting problem #2 is being caused by some asynchronous calls hanging out from the first attempt but no matter how long I wait those events don't fire until I kick of the code via the button. So why is the requestFileSystem call failing even though it is waiting for deviceready and why is the other code getting intermingled? Any thoughts are appreciated. <!DOCTYPE html> <html> <head> <title>FileReader Example</title> <script type="text/javascript" charset="utf-8" src="cordova.js"></script> <script type="text/javascript" charset="utf-8"> // Wait for device API libraries to load // document.addEventListener("deviceready", onDeviceReady, false); // device APIs are available // function onDeviceReady() { alert("1"); window.requestFileSystem(LocalFileSystem.PERSISTENT, 0, gotFS, fail); } function gotFS(fileSystem) { alert("2"); fileSystem.root.getFile("readme.txt", null, gotFileEntry, fail); } function gotFileEntry(fileEntry) { alert("3"); fileEntry.file(gotFile, fail); } function gotFile(file) { alert("4"); readDataUrl(file); alert("5"); readAsText(file); } function readDataUrl(file) { alert("6"); var reader = new FileReader(); reader.onloadend = function (evt) { console.log("Read as data URL"); console.log(evt.target.result); }; reader.readAsDataURL(file); } function readAsText(file) { alert("7"); var reader = new FileReader(); reader.onloadend = function (evt) { console.log("Read as text"); console.log(evt.target.result); }; reader.readAsText(file); } function fail(error) { alert("8"); console.log(error.code); } </script> </head> <body> <h1>Example</h1> <p>Read File</p> <button onclick="onDeviceReady();">Read File</button> </body> </html>

• How do I get a delete trigger working using fluent API in CTP5?

  - by user668472

  I am having trouble getting referential integrity dialled down enough to allow my delete trigger to fire. I have a dependent entity with three FKs. I want it to be deleted when any of the principal entities is deleted. For principal entities Role and OrgUnit (see below) I can rely on conventions to create the required one-many relationship and cascade delete does what I want, ie: Association is removed when either principal is deleted. For Member, however, I have multiple cascade delete paths (not shown here) which SQL Server doesn't like, so I need to use fluent API to disable cascade deletes. Here is my (simplified) model: public class Association { public int id { get; set; } public int roleid { get; set; } public virtual Role role { get; set; } public int? memberid { get; set; } public virtual Member member { get; set; } public int orgunitid { get; set; } public int OrgUnit orgunit { get; set; } } public class Role { public int id { get; set; } public virtual ICollection<Association> associations { get; set; } } public class Member { public int id { get; set; } public virtual ICollection<Association> associations { get; set; } } public class Organization { public int id { get; set; } public virtual ICollection<Association> associations { get; set; } } My first run at fluent API code looks like this: protected override void OnModelCreating(System.Data.Entity.ModelConfiguration.ModelBuilder modelBuilder) { DbDatabase.SetInitializer<ConfDB_Model>(new ConfDBInitializer()); modelBuilder.Entity<Member>() .HasMany(m=>m.assocations) .WithOptional(a=>a.member) .HasForeignKey(a=>a.memberId) .WillCascadeOnDelete(false); } My seed function creates the delete trigger: protected override void Seed(ConfDB_Model context) { context.Database.SqlCommand("CREATE TRIGGER MemberAssocTrigger ON dbo.Members FOR DELETE AS DELETE Assocations FROM Associations, deleted WHERE Associations.memberId = deleted.id"); } PROBLEM: When I run this, create a Role, a Member, an OrgUnit, and an Association tying the three together all is fine. When I delete the Role, the Association gets cascade deleted as I expect. HOWEVER when I delete the Member I get an exception with a referential integrity error. I have tried setting ON CASCADE SET NULL because my memberid FK is nullable but SQL complains again about multiple cascade paths, so apparently I can cascade nothing in the Member-Association relationship. To get this to work I must add the following code to Seed(): context.Database.SqlCommand("ALTER TABLE dbo.ACLEntries DROP CONSTRAINT member_aclentries"); As you can see, this drops the constraint created by the model builder. QUESTION: this feels like a complete hack. Is there a way using fluent API for me to say that referential integrity should NOT be checked, or otherwise to get it to relax enough for the Member delete to work and allow the trigger to be fired? Thanks in advance for any help you can offer. Although fluent APIs may be "fluent" I find them far from intuitive.

• onCommand on button not firing inside gridView??

  - by sah302

  This is really driving me crazy. I've got a button inside a gridview to remove that item from the gridview (its datasource is a list). I've got the list being saved to session anytime a change is being made to it, and on page_load check if that session variable is empty, if not, then set that list to bind to the gridview. Code Behind: Public accomplishmentTypeDao As New AccomplishmentTypeDao() Public accomplishmentDao As New AccomplishmentDao() Public userDao As New UserDao() Public facultyDictionary As New Dictionary(Of Guid, String) Public facultyList As New List(Of User) Public associatedFaculty As New List(Of User) Public facultyId As New Guid Protected Sub Page_Load(ByVal sender As Object, ByVal e As System.EventArgs) Handles Me.Load 'If Not Session("associatedFaculty") Is Nothing Then' ' Dim associatedFacultyArray As User() = DirectCast(Session("associatedFaculty"), User())' ' associatedFaculty = associatedFacultyArray.ToList()' 'End If' Page.Title = "Add a New Faculty Accomplishment" ddlAccomplishmentType.DataSource = accomplishmentTypeDao.getEntireTable() ddlAccomplishmentType.DataTextField = "Name" ddlAccomplishmentType.DataValueField = "Id" ddlAccomplishmentType.DataBind() facultyList = userDao.getListOfUsersByUserGroupName("Faculty") For Each faculty As User In facultyList facultyDictionary.Add(faculty.Id, faculty.LastName & ", " & faculty.FirstName) Next If Not Page.IsPostBack Then ddlFacultyList.DataSource = facultyDictionary ddlFacultyList.DataTextField = "Value" ddlFacultyList.DataValueField = "Key" ddlFacultyList.DataBind() End If gvAssociatedUsers.DataSource = associatedFaculty gvAssociatedUsers.DataBind() End Sub Protected Sub deleteUser(ByVal sender As Object, ByVal e As System.Web.UI.WebControls.CommandEventArgs) facultyId = New Guid(e.CommandArgument.ToString()) associatedFaculty.Remove(associatedFaculty.Find(Function(user) user.Id = facultyId)) Session("associatedFaculty") = associatedFaculty.ToArray() gvAssociatedUsers.DataBind() upAssociatedFaculty.Update() End Sub Protected Sub btnAddUser_Click(ByVal sender As Object, ByVal e As EventArgs) Handles btnAddUser.Click facultyId = New Guid(ddlFacultyList.SelectedValue) associatedFaculty.Add(facultyList.Find(Function(user) user.Id = facultyId)) Session.Add("associatedFaculty", associatedFaculty.ToArray()) gvAssociatedUsers.DataBind() upAssociatedFaculty.Update() End Sub Protected Sub Delete(ByVal sender As Object, ByVal e As System.Web.UI.WebControls.CommandEventArgs) End Sub End Class Markup: <asp:UpdatePanel ID="upAssociatedFaculty" runat="server" UpdateMode="Conditional"> <ContentTemplate> <p><b>Created By:</b> <asp:Label ID="lblCreatedBy" runat="server"></asp:Label></p> <p><b>Accomplishment Type: </b><asp:DropDownList ID="ddlAccomplishmentType" runat="server"></asp:DropDownList></p> <p><b>Accomplishment Applies To: </b><asp:DropDownList ID="ddlFacultyList" runat="server"></asp:DropDownList> &nbsp;<asp:Button ID="btnAddUser" runat="server" Text="Add Faculty" OnClientClick="incrementCounter();" /></p> <p> <asp:GridView ID="gvAssociatedUsers" runat="server" AutoGenerateColumns="false" GridLines="None" ShowHeader="false"> <Columns> <asp:BoundField DataField="Id" HeaderText="Id" Visible="False" /> <asp:TemplateField ShowHeader="False"> <ItemTemplate> <span style="margin-left: 15px;"> <p><%#Eval("LastName")%>, <%#Eval("FirstName")%> <asp:Button ID="btnUnassignUser" runat="server" CausesValidation="false" CommandArgument='<%# Eval("Id") %>' CommandName="Delete" OnCommand="deleteUser" Text='Remove' /></p> </span> </ItemTemplate> </asp:TemplateField> </Columns> <EmptyDataTemplate> <em>There are currently no faculty associated with this accomplishment.</em> </EmptyDataTemplate> </asp:GridView> </p> </ContentTemplate> </asp:UpdatePanel> Now here is the crazy part I am simply boggled by, if I uncomment the If Not Session... block of page_load, then deleteUser will never fire when btnUnassignUser is clicked. If I keep it commented out...it fires no problem, but then of course my list can never have more than one item since I am not loading the saved list from session into the gridview but just a fresh one. But the button click is being registered, because page_load is being stepped through again when I am viewing in debug mode, just deleteUser never fires. Why is this happening?? And how can I fix it??

• Designing different Factory classes (and what to use as argument to the factories!)

  - by devoured elysium

  Let's say we have the following piece of code: public class Event { } public class SportEvent1 : Event { } public class SportEvent2 : Event { } public class MedicalEvent1 : Event { } public class MedicalEvent2 : Event { } public interface IEventFactory { bool AcceptsInputString(string inputString); Event CreateEvent(string inputString); } public class EventFactory { private List<IEventFactory> factories = new List<IEventFactory>(); public void AddFactory(IEventFactory factory) { factories.Add(factory); } //I don't see a point in defining a RemoveFactory() so I won't. public Event CreateEvent(string inputString) { try { //iterate through all factories. If one and only one of them accepts //the string, generate the event. Otherwise, throw an exception. return factories.Single(factory => factory.AcceptsInputString(inputString)).CreateEvent(inputString); } catch (InvalidOperationException e) { throw new InvalidOperationException("No valid factory found to generate this kind of Event!", e); } } } public class SportEvent1Factory : IEventFactory { public bool AcceptsInputString(string inputString) { return inputString.StartsWith("SportEvent1"); } public Event CreateEvent(string inputString) { return new SportEvent1(); } } public class MedicalEvent1Factory : IEventFactory { public bool AcceptsInputString(string inputString) { return inputString.StartsWith("MedicalEvent1"); } public Event CreateEvent(string inputString) { return new MedicalEvent1(); } } And here is the code that runs it: static void Main(string[] args) { EventFactory medicalEventFactory = new EventFactory(); medicalEventFactory.AddFactory(new MedicalEvent1Factory()); medicalEventFactory.AddFactory(new MedicalEvent2Factory()); EventFactory sportsEventFactory = new EventFactory(); sportsEventFactory.AddFactory(new SportEvent1Factory()); sportsEventFactory.AddFactory(new SportEvent2Factory()); } I have a couple of questions: Instead of having to add factories here in the main method of my application, should I try to redesign my EventFactory class so it is an abstract factory? It'd be better if I had a way of not having to manually add EventFactories every time I want to use them. So I could just instantiate MedicalFactory and SportsFactory. Should I make a Factory of factories? Maybe that'd be over-engineering? As you have probably noticed, I am using a inputString string as argument to feed the factories. I have an application that lets the user create his own events but also to load/save them from text files. Later, I might want to add other kinds of files, XML, sql connections, whatever. The only way I can think of that would allow me to make this work is having an internal format (I choose a string, as it's easy to understand). How would you make this? I assume this is a recurrent situation, probably most of you know of any other more intelligent approach to this. I am then only looping in the EventFactory for all the factories in its list to check if any of them accepts the input string. If one does, then it asks it to generate the Event. If you find there is something wrong or awkward with the method I'm using to make this happen, I'd be happy to hear about different implementations. Thanks! PS: Although I don't show it in here, all the different kind of events have different properties, so I have to generate them with different arguments (SportEvent1 might have SportName and Duration properties, that have to be put in the inputString as argument).

• How can I provide maximum integration between a calendar-like webapp and desktop calendar applicatio

  - by Joshua Carmody

  I've been assigned to upgrade/rewrite a webapp that my company uses to schedule conference calls. One of the goals of the upgrade is to improve integration between the application and our user's Outlook calendars (and ideally other calendar programs as well). At present, when a user is viewing the details of a scheduled conference call on the webapp, they can click an "Add to Outlook calendar" link, which points them to a dynamically generated .ical file. On most of our users' systems, Outlook opens the file by default, bringing up the "create calendar appointment" window with the concall information pre-populated. This link creates a 1-time appointment only, and has to be clicked on for each occurrence of the call. So if a call happened every Monday in June, you would have to click 4 links to add all the appointments to your calendar. This is the full extent of our current level of integration. Ideally, we will be able to upgrade the system so that users can "subscribe" to a con call, which would mean not just the current call, but all calls in a reoccurring series would appear in the user's calendar with a single click. If one call in a series was cancelled, or rescheduled, that call's appointment would change in the users' calendar, without the user having to do anything, and without upsetting the rest of the series' appointments. Also, any changes to the call's info (say, the phone number was changed) would automatically be updated in the Outlook calendars of anyone who subscribed, without them having to come back to the webapp to double-check that their information is up to date. Ideally this would also work with other popular calendar programs, as well as Google Calendar. I don't know if we'll be able to achieve that level of integration, but I'd like to get as close to that as we can. Additional details and challenges: We aren't running Exchange on a public server, and I'm not likely to be able to get that changed Assume that our users are basically "the general internet public". Our users are not members of our office's network, nor can they be. We can't set up network logins or Exchange accounts for them. Some of our users are not using Outlook, but some other calendar program. Of the ones that are using Outlook, not all are using the same version. We have users in more than 50 countries that are using this webapp. Synchronization would be one-directional. Nobody can make changes in their own calendars and expect the server to reflect them/replicate them to other users Current conference calling application is written in ColdFusion. Rewrite will probably be in ASP.NET, but I haven't confirmed that yet. Solutions that work with either or both technologies are appreciated. I know that .ical files can theoretically contain more than one event, but in my own experiments I haven't had success in getting Outlook (2003) to add more than one event at a time using the .ical file method. Maybe someone knows how to set up a multi-event .ical file that Outlook will accept? Could a link to such an .ical file be "subscribed" to? Is there such thing as a calendar RSS feed? Could I simulate running an exchange server? Any other ideas? Thanks everyone!

• JSF2 - Problems with Composite Components and Validatiors

  - by Shadowman

  I've created some Facelets to make developing our pages easier. Particularly, I've created a series of Facelets for input components. I have 1 Facelet, <xxx:input /> that displays a label around the input field. Beyond that, I have Facelets like <xxx:inputText /> and <xxx:inputSecret /> that render the actual input field. Each of these makes use of <xxx:input /> to display the label. The Facelet looks something like this: <html ...> <composite:interface> ... </composite:interface> <composite:implementation> <label><h:outputText value="#{cc.attrs.labelText}" /></label> <composite:insertChildren /> </composite:implementation> </html> The <xxx:inputText /> Facelet would then look like this... <html ...> <composite:interface> ... </composite:interface> <composite:implementation> <xxx:input labelText=...> <h:inputText id="myinput" ... /> </xxx:input> </composite:implementation> </html> Everything renders just fine, but I am having troubles when trying to add <f:validator /> or other validation tags. From what I've read, I have to add a tag to my Facelet. So, I added <composite:editableValueHolder name="myinput" targets="myinput" /> line in the interface section. However, I still do not see my validator being fired. I have something like this in my .xhtml file... ... <xxx:inputText value="..."> <f:validateLength minimum="10" /> </xxx:inputText> ... Regardless of the input I enter, the validator never seems to fire and I never get an error message. A coworker suggested that it is due to the target ID I am using and the fact that it is wrapped by the <xxx:input /> Facelet. Do I need to incorporate the parent component ID in my target definition? Is there something else that I'm missing? It works just fine if I exclude the <xxx:input /> Facelet, so I'm assuming it's something related to that, but don't know how to solve it. Any help you can provide is GREATLY appreciated.

• simplexml help how do I parse this?

  - by bbutle01

  I haven't done any xml projects, so I'm not quite sure what to do with this data... I'm using curl to make a request to salesforce, and they give me back a response that I need to parse. I want to use simplexml. Here's part of the response: <soapenv:Envelope xmlns:soapenv="http://schemas.xmlsoap.org/soap/envelope/" xmlns="urn:partner.soap.sforce.com" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"> <soapenv:Body> <loginResponse> <result> <metadataServerUrl> https://na6-api.salesforce.com/services/Soap/m/18.0/ </metadataServerUrl> <passwordExpired> false </passwordExpired> <sandbox> false </sandbox> <serverUrl> https://na6-api.salesforce.com/services/Soap/u/18.0/ </serverUrl> <sessionId> !AQ4AQLtDIqY. </sessionId> <userId> </userId> <userInfo> <accessibilityMode> false </accessibilityMode> <currencySymbol> $ </currencySymbol> <orgDefaultCurrencyIsoCode> USD </orgDefaultCurrencyIsoCode> <orgDisallowHtmlAttachments> false </orgDisallowHtmlAttachments> <orgHasPersonAccounts> false </orgHasPersonAccounts> <organizationId> </organizationId> <organizationMultiCurrency> false </organizationMultiCurrency> <organizationName> Ox </organizationName> <profileId> sdfgsdfg </profileId> <roleId> sdfgsdfg </roleId> <userDefaultCurrencyIsoCode xsi:nil="true"/> <userEmail> ###@gmail.com </userEmail> <userFullName> ### ### </userFullName> <userId> asdfasdf </userId> <userLanguage> en_US </userLanguage> <userLocale> en_US </userLocale> <userName> [email protected] </userName> <userTimeZone> America/Chicago </userTimeZone> <userType> Standard </userType> <userUiSkin> Theme3 </userUiSkin> </userInfo> </result> </loginResponse> </soapenv:Body> </soapenv:Envelope> Anyway, I expected to feed that stuff (we'll call it data) into $results = simplexml_load_string($data); var_dump($results); And that would give me all the data back... and then to access specific parts, it would be $results-body-loginResponse-blah-blah... But It's not giving me that, it's not really giving me anything back, just an empty simple xml object... So one website made me think I might need an XSLT to read this correctly. Or something else made me think it's because I don't have at the top. Help!

• Wordpress blog with Joomla?

  - by user427902

  Hi, I had this Wordpress installation which was installed in a subfolder (not root). Like http: //server/blog/. Now, I installed Joomla on the root (http: //server/). Everything seems to be working fine with the Joomla part. However, the blog part is messed up. If I try to browse the homepage of my blog which is http: //server/blog/ it works like a charm. But while trying to view individual blog pages like say, http: //server/blog/some_category/some_post I get a Joomla 404 page. So, I was wondering if it was possible to use both Wordpress and Joomla in the same server in the setup I am trying to. Let me clarify that I am NOT looking to integrate user login and other such things. I just want the blog to be functional under a subfolder while I run the Joomla site in the root. So, what is the correct way to go about it. Can this be solved by any .config edits or something else? Edit: Here's the .htaccess for Joomla ... (I can't find any .htaccess for Wp though, still looking for it.) ## # @version $Id: htaccess.txt 14401 2010-01-26 14:10:00Z louis $ # @package Joomla # @copyright Copyright (C) 2005 - 2010 Open Source Matters.
