  • Flex 3 - Image cache

    - by BS_C3
    Hello Community. I'm doing an Image Cache following this method: http://www.brandondement.com/blog/2009/08/18/creating-an-image-cache-with-actionscript-3/ I copied the two as classes, renaming them CachedImage and CachedImageMap. The thing is that I don't want to store the image after being loaded a first time, but while the application is being loaded. For that, I've created a function that is called by the application pre-initialize event. This is how it looks: private function loadImages():void { var im:CachedImage = new CachedImage; var sources:ArrayCollection = new ArrayCollection; for each(var cs in divisionData.division.collections.collection.collectionSelection) { sources.addItem(cs.toString()); } for each(var se in divisionData.division.collections.collection.searchEngine) { sources.addItem(se.toString()); } for each( var source:String in sources) { im.source = source; im.load(source); } } The sources are properly retrieved. However, even if I use the load method, I do not get the "complete" event... As if the image is not being loaded... How is that? Any help would be appreciated. Thanks in advance. Regards, BS_C3

  • DOMNode reference doesn't work anymore after appending it to another element twice

    - by Robbie Groenewoudt
    Hi, I'm using the a wrapper around the PHP5-class DOMDocument to generate my HTML. This makes it easy to modify the HTML by using the DOM. An example is creating element #1 and adding it to the element #2 and still be able to modify element #1 directly. A problem arises however with the following: Element #1 is added to element #2 Element #2 is added to element #3 Element #1 is modified but no changes are visible in the DOM of element #3 (which contains #1 and #2) A simplified sample code: <?php $doc1 = new DOMDocument(); $el1 = $doc1->createElement('h1', 'Hello'); $doc1->appendChild($el1); $doc2 = new DOMDocument(); $el2 = $doc2->createElement('h2', 'World'); $doc2->appendChild($el2); $doc3 = new DOMDocument(); $el3 = $doc3->createElement('h3', 'Today'); $doc3->appendChild($el3); // Import el1 into el2 $el1 = $doc2->importNode($el1, true); $el2->appendChild( $el1 ); $doc1 = $doc2; // Import el2 into el3 $el2 = $doc3->importNode($el2, true); //$el1 = $doc3->importNode($el1, true); Necessary? $el3->appendChild($el2); $doc2 = $doc3; // Modify el1 $el1->nodeValue = "Boo"; // This doesn't work? //$el2->nodeValue = "Boo"; // Changing element2 or 3 works... // Display result echo $doc3->saveHTML(); ?>` Any idea's on why modifying $el1 won't work? (While $el2 works fine) Or an easy way to set $el1 to the right element?

  • How do I secure a .NET Web Service for use by an iPhone application?

    - by David A Gibson
    Hello, The title says it all, I have a Web Service written in .NET that provides data for an iPhone application. It will also allow the application make a "reservation." Currently it's all internal to the corporate network but obviously when the iPhone application is published I will need ensure the Web Service is available externally. How would I go about securing the Web Service? There are two aspects I'm looking into: Authentication for accessing the web service Protection for the data being transferred I'm no so bothered about the data being passed back and forth as it will be viewable in the application anyway (which will be free). The key issue for me is preventing users from accessing the Web Service and making reservations themselves. At the moment I am considering encrypting any strings in the XML data passed back and forth so only the client can effectively use the web service sidestepping the need for authentication and providing protection for the data. This is the only model I have seen but I think the overheads on the iPhone and even for the web service make for a poor user experience. Any solutions at all would be most welcome? Thanks

  • Perl: How do I capture Chinese input via SCIM with STDIN?

    - by KCArpe
    Hi, I use SCIM on Linux for Chinese and Japanese language input. Unfortunately, when I try to capture input using Perl's STDIN, the input is crazy. As roman characters are typed, SCIM tries to guess the correct final characters. ^H (backspace) codes are used to delete previously suggested chars on the command line. (As you type, SCIM tries to guess final Asian chars and displays them.) However, these backspace chars are shown literally as ^H and not interpreted correctly. Example one-liner: perl -e 'print "Chinese: "; my $s = <STDIN>; print $s' When I enable SCIM Chinese or Japanese language input, as I type, e.g., nihao = ??, here is the result: ?^H?^H?^H?^H?^H??^H^H??^H^H??^H^H??^H^H??^H^H??^H^H??^H^H??^H^H??^H^H?? At the very end of this string, you can see "??" (nihao/hello). At a normal bash prompt, if I type nihao (with Chinese enabled), the results is perfect. This has something to do with interpretation of backspace chars (or control chars) during Perl's STDIN. The same thing happens when using command 'read' in Bash. Witness: read -p 'Chinese: ' s && echo $s Cheers, Kevin

  • Trouble accessing data in relationships in Ember

    - by user3618430
    I'm having trouble saving data in this model relationship. My models are as follows: App.Flow = DS.Model.extend({ title: DS.attr('string'), content: DS.attr('string'), isCustom: DS.attr('boolean'), params: DS.hasMany('parameter', {async: true}) }); App.Parameter = DS.Model.extend({ flow: DS.belongsTo('flow'), param: DS.attr('string'), param_tooltip: DS.attr('string'), param_value: DS.attr('string') }); As you can see, I want Flows to have multiple Parameters. I have a rudimentary setup using Flow and Parameter fixtures, which behave as expected in the templates. However, when I try to create new ones in the controller, I have trouble setting the flow and parameter values correctly. var p = this.store.createRecord('parameter', { param: "foo", param_tooltip: "world", param_value: "hello" }); var f = this.store.createRecord('flow', { title: 'job', content: title, isCustom: true, params: [p] // doesn't seem to work }); f.set('params', [p]); // doesn't seem to work p.set('flow', f); // also doesn't seem to work // Save the new model p.save(); f.save(); I've tried a lot of solutions after staring at this and StackOverflow for a while (not just the ones listed). I'm not really sure what to try next. One thing that I noticed in the Ember inspector was that the ids of these created elements were not integers (they were something like the string 'fixture_0'), but I'm not really sure why that would be, whether its related, or how to fix it. Thanks!

  • Help improve this Javascript code?

    - by Galilyou
    Hello SO, In short, I'm dealing with Telerik's RadTreeView, and I want enable checking all the child nodes if the user checked the parent node. Simple enough! OK here's my code that handles OnClientNodeChecked event of the TreeView: function UpdateAllChildren(nodes, checked) { var i; for (i = 0; i < nodes.get_count(); i++) { var currentNode = nodes.getNode(i); currentNode.set_checked(checked); alert("now processing: " + currentNode.get_text()); if (currentNode.get_nodes().get_count() > 0) { UpdateAllChildren(currentNode.get_nodes(), checked); } } } function ClientNodeChecked(sender, eventArgs) { var node = eventArgs.get_node(); UpdateAllChildren(node.get_nodes(), node.get_checked()); } And here's the TreeView's markup: <telerik:RadTreeView ID="RadTreeView1" runat="server" CheckBoxes="True" OnClientNodeChecked="ClientNodeChecked"></telerik:RadTreeView> The tree contains quite a lot of nodes, and this is causing my targeted browser (ehm, that's IE7) to really slow down while running it. Furthermore IE7 displays an error message asking me to stop the page from running scripts as it's might make my computer not responsive (yeah, scary enough). So what do you guys propose to optimize this code? Thanks in advance

  • Android -- SDK/IDE Layout Bug (w/Custom Layouts)??

    - by borg17of20
    Hello all, Can someone tell me if this is a bug in the SDK/IDE: Any custom or extended layout I add to my layout XML causes the IDE to ignore the fact that there are any child views of that layout (they just disappear from the outline view/window), thus making them uneditable via the properties view/window. (I need to extend a layout to make onSetAlpha() public) FYI: I'm developing for Android 1.5 and up, using all the latest plug-ins/updates in Eclipse Here is a simple example of a layout XML and the extended Layout that causes this error. [Extended Layout] package com.test; public class CustomLinearLayout extends LinearLayout { public CustomLinearLayout(Context context, AttributeSet attrs) { super(context, attrs); } public CustomLinearLayout(Context context) { super(context); } } [Simple layout XML] <?xml version="1.0" encoding="utf-8"?> <com.test.CustomLinearLayout xmlns:android="http://schemas.android.com/apk/res/android" android:layout_width="wrap_content" android:layout_height="wrap_content"> <ImageView android:id="@+id/ImageView01" android:layout_width="wrap_content" android:layout_height="wrap_content"></ImageView> </com.test.CustomLinearLayout> ImageView01 is not visible or editable in the properties or outline views/windows.

  • C++ meta-splat function

    - by aaa
    hello. Is there an existing function (in boost mpl or fusion) to splat meta-vector to variadic template arguments? for example: splat<vector<T1, T2, ...>, function>::type same as function<T1, T2, ...> my search have not found one, and I do not want to reinvent one if it already exists. edit: after some tinkering, apparently it's next to impossible to accomplish this in general way, as it would require declaring full template template parameter list for all possible cases. only reasonable solution is to use macro: #define splat(name, function) \ template<class T, ...> struct name; \ template<class T> \ struct name<T,typename boost::enable_if_c< \ result_of::size<T>::value == 1>::type> { \ typedef function< \ typename result_of::value_at_c<T,0>::type \ > type; \ }; Oh well. thank you

  • How Optimize sql query make it faster

    - by user502083
    Hello every one : I have a very simple small database, 2 of tables are: Node (Node_ID, Node_name, Node_Date) : Node_ID is primary key Citation (Origin_Id, Target_Id) : PRIMARY KEY (Origin_Id, Target_Id) each is FK in Node Now I write a query that first find all citations that their Origin_Id has a specific date and then I want to know what are the target dates of these records. I'm using sqlite in python the Node table has 3000 record and Citation has 9000 records, and my query is like this in a function: def cited_years_list(self, date): c=self.cur try: c.execute("""select n.Node_Date,count(*) from Node n INNER JOIN (select c.Origin_Id AS Origin_Id, c.Target_Id AS Target_Id, n.Node_Date AS Date from CITATION c INNER JOIN NODE n ON c.Origin_Id=n.Node_Id where CAST(n.Node_Date as INT)={0}) VW ON VW.Target_Id=n.Node_Id GROUP BY n.Node_Date;""".format(date)) cited_years=c.fetchall() self.conn.commit() print('Cited Years are : \n ',str(cited_years)) except Exception as e: print('Cited Years retrival failed ',e) return cited_years Then I call this function for some specific years, But it's crazy slowwwwwwwww :( (around 1 min for a specific year) Although my query works fine, it is slow. would you please give me a suggestion to make it faster? I'd appreciate any idea about optimizing this query :) I also should mention that I have indices on Origin_Id and Target_Id, so the inner join should be pretty fast, but it's not!!!

  • why when I delete a parent on a one to many relationship on grails the beforeInsert event is called

  • Why does the '#weight' property sometimes not have any effect in Drupal forms?

    - by Adrian
    Hello, I'm trying to create a node form for a custom type. I have organic groups and taxonomy both enabled, but want their elements to come out in a non-standard order. So I've implemented hook_form_alter and set the #weight property of the og_nodeapi subarray to -1000, but it still goes after taxonomy and menu. I even tried changing the subarray to a fieldset (to force it to actually be rendered), but no dice. I also tried setting $form['taxonomy']['#weight'] = 1000 (I have two vocabs so it's already being rendered as a fieldset) but that didn't work either. I set the weight of my module very high and confirmed in the system table that it is indeed the highest module on the site - so I'm all out of ideas. Any suggestions? Update: While I'm not exactly sure how, I did manage to get the taxonomy fieldset to sink below everything else, but now I have a related problem that's hopefully more manageable to understand. Within the taxonomy fieldset, I have two items (a tags and a multi-select), and I wanted to add some instructions in hook_form_alter as follows: $form['taxonomy']['instructions'] = array( '#value' => "These are the instructions", '#weight' => -1, ); You guessed it, this appears after the terms inserted by the taxonomy module. However, if I change this to a fieldset: $form['taxonomy']['instructions'] = array( '#type' => 'fieldset', // <-- here '#title' => 'Instructions', // <-- and here for good measure '#value' => "These are the instructions", '#weight' => -1, ); then it magically floats to the top as I'd intended. I also tried textarea (this also worked) and explicitly saying markup (this did not). So basically, changing the type from "markup" (the default IIRC) to "fieldset" has the effect of no longer ignoring its weight.

  • Recommended/Standard image thumbnails sizes

    - by Rakan
    Hello, Based on my experience in web development, HTML page designs for every website may have different < img tags showing the same image in different sizes. i.e: the website's main page might show the image in 500*500, the listing page might show it in 200*150 and other sections of the website will use different sizes. As you can see the ratios of the images to be displayed to the user are different and therefore will cause a problem in having the image stretched, pixelated and/or other quality problems. How i currently handle this issue is by using a jQuery cropping tool to make the user select the area to crop the thumbnail from. the cropped image is then resized using imagick to fit every position in the page design. However, although i can force the user to crop an image based on a pre-defined ratio, the HTML will still contain image placeholders which require a different ratio for its thumbnail. So for every image, i will have to force the user to crop the uploaded image based on every possible ratio my site requires. I don't think this is a friendly solution, how would you do it? is there a standard/recommended ratio for the web? Thanks

  • Strange behaviour of CheckBox and TwoWay bound property

    - by walkor
    Hello, everyone. I fell in the following situation: I have a main UserControl with a DataGrid (which contains List). I need to show different panels depending on properties of the selected row(object). So i've created 2 controls and included them into this main control. Main control has 2 public properties - public List<ComplexObject> SourceList { get; set; } and public ComplexObject CurrentObject { get; set; } Pseudo-code: <UserControl x:Name="Main"> <DataGrid ItemsSource="{Binding SourceList}" SelectedItem="{Binding CurrentObject, Mode=TwoWay}"/> <Controls:RightPanelFirst Visibility="condition2"/> <Controls:RightPanelSecond Visibility="condition2"/> </UserControl> RightPanelFirst and RightPanelSecond have the following xaml: <UserControl> <... content here...> <CheckBox IsChecked="{Binding CurrentObject.ComplexProperty.SimpleProperty1, Mode=TwoWay}"> <CheckBox IsChecked="{Binding CurrentObject.ComplexProperty.SimpleProperty2, Mode=TwoWay}" x:Name="cbSecond"> <TextBox IsEnabled="{Binding IsChecked, ElementName=cbSecond}"/> </UserControl> So, my actual steps: Check both checkboxes (object values are set to true) Make other actions in code behind which modify CurrentObject. Then i want UI to reflect the changes, so I call NotifyPropertyChanged("CurrentObject"); SimpleProperty1 remains the same, but SimpleProperty2 resets to false I have no idea why this happens, can anyone help me please? Silverlight drives me mad.

  • Replace string with incremented value

    - by Andrei
    Hello, I'm trying to write a CSS parser to automatically dispatch URLs in background images to different subdomains in order to parallelize downloads. Basically, I want to replace things like url(/assets/some-background-image.png) with url(http://assets[increment].domain.com/assets/some-background-image.png) I'm using this inside a class that I eventually want to evolve into doing various CSS parsing tasks. Here are the relevant parts of the class : private function parallelizeDownloads(){ static $counter = 1; $newURL = "url(http://assets".$counter.".domain.com"; The counter needs to be reset when it reaches 4 in order to limit to 4 subdomains. if ($counter == 4) { $counter = 1; } $counter ++; return $newURL; } public function replaceURLs() { This is mostly nonsense, but I know the code I'm looking for looks somewhat like this. Note : $this-css contains the CSS string. preg_match("/url/i",$this->css,$match); foreach($match as $URL) { $newURL = self::parallelizeDownloads(); $this->css = str_replace($match, $newURL,$this->css); } }

  • How to test if a user has SELECTED a file to upload ?

    Hello, on a page, i have : if (!empty($_FILES['logo']['name'])) { $dossier = 'upload/'; $fichier = basename($_FILES['logo']['name']); $taille_maxi = 100000; $taille = filesize($_FILES['logo']['tmp_name']); $extensions = array('.png', '.jpg', '.jpeg'); $extension = strrchr($_FILES['logo']['name'], '.'); if(!in_array($extension, $extensions)) { $erreur = 'ERROR you must upload the right type'; } if($taille>$taille_maxi) { $erreur = 'too heavy'; } if(!empty($erreur)) { ....................... } The problem is, if the users wants to edit information WITHOUT uploading a LOGO, it raises an error : 'error you must upload the right type' So, if a user didn't put anything in the inputbox in order to upload it, i don't want to enter in these conditions test. i tested : if (!empty($_FILES['logo']['name']) and if (isset($_FILES['logo']['name']) but both doesn't seems to work. Any ideas? edit : maybe i wasn't so clear, i don't want to test if he uploaded a logo, i want to test IF he selected a file to upload, because right now, if he doesn't select a file to upload, php raises an error telling he must upload with the right format. thanks.

Here's some background information: the fields we're primarily concerned with are: n_number, alert_id, end_date For all three scenarios we are comparing candidate records against the following records in the database (for the sake of argument, let's assume they're the only records in the database so far): alert_id|| n_number|| end_date ------------------------------------- 1|| 5|| _______ 2|| 6|| 10/25/2009 Scenario 1: The user enters a new record: alert_id 1 n_number 5 end_date NULL Objective: prevent the user from committing duplicate rows Scenario 2: The user enters a new record: alert_id 1 n_number 10 end_date NULL Objective: Notify the user that this alert_id already exists, but allow the user the ability to commit the row, if desired. Scenario 3: The user enters a new record: alert_id 2 n_number 6 end_date NULL Objective: Notify the user that this alert_id has occurred in the past (i.e. it has a not-null end_date), but allow the user to commit the row, if desired. I've written the code, which seems to comply with the first two scenarios, but prevents me from fulfilling the third. Issues: When I enter the third scenario case, I am prompted to commit the record, but when I attempt this, the "duplicate_stop" alert pops up, preventing me. Issues: I'm getting the following error: ORA-01843: not a valid month. While testing the code for the third scenario in Toad (hard-coding the values, etc) things seemed to be fine. Why would I encounter these problems at run-time? Help is very much appreciated. Thank you

  • C# + Querying XML with LINQ

    - by user336786
    Hello, I'm learning to use LINQ. I have seen some videos online that have really impressed me. In an effort to learn LINQ myself, I decided to try to write a query to the NOAA web service. If you put "http://www.weather.gov/forecasts/xml/sample_products/browser_interface/ndfdBrowserClientByDay.php?zipCodeList=20001&format=24+hourly&startDate=2010-06-10&numDays=5" in your browser's address bar, you will see some XML. I have successfully retrieved that XML in a C# program. I am loading the XML into a LINQable entity by doing the following: string xml = QueryWeatherService(); XDocument weather = XDocument.Parse(xml); I have a class called DailyForecast defined as follows: public class DailyForecast { public float HighTemperature { get; set; } public float LowTemperature { get; set; } public float PrecipitationPossibility { get; set; } public string WeatherSummary { get; set; } } I'm trying write a LINQ query that adheres to the structure of my DailyForecast class. At this time, I've only gotten to this far: var results = from day in response.Descendants("parameters") select day; Not very far I know. Because of the structure of the XML returned, I'm not sure it is possible to solely use a LINQ query. I think the only way to do this is via a loop and traverse the XML. I'm seeking someone to correct me if I'm wrong. Can someone please tell me if I can get results using purely LINQ that adhere to the structure of the DailyForecast class? If so, how? Thank you!

  • Create a new webpage using a WCF service

    - by sweeney
    Hello, I'd like to create WCF operation contract which consumes a string, produces a public webpage and then returns the address of this new page. [ServiceContract(Namespace = "")] public class DatabaseService { [OperationContract] public string BuildPage(string fileName, string html) { //writes html to file //returns public file url } } This doesn't seem like it should be complicated but i cant figure out how to do it. So far what i've tried is this: [OperationContract] public string PrintToFile(string name, string text) { FileInfo f = new FileInfo(name); StreamWriter w = f.AppendText(); w.Write(text); w.Close(); return f.Directory.ToString(); } Here's the problem. This does not create a file in the web root, it creates it in the directory where the webdav server is running. When i run this on an IIS server it seems to do nothing at all (at least not that i can tell). How can I get a handle to the webroot programmatically so that i can place the resultant file there and then return the public URL? I can tack on the domain name after the fact without issue so if it only returns the relative path to the file that's fine. Thanks, brian

  • Why Does My Vector<PEVENTLOGRECORD> Mysteriously Get Cleared?

    - by Eric
    Hello everyone, I am making a program that reads and stores data from Windows EventLog files (.evt) in C++. I am using the calls OpenBackupEventLog(ServerName, FileName) and ReadEventLog(...). Also using this: PEVENTLOGRECORD Anyway, without supplying all of the code, here is the basic idea: 1. I get a handle to the .evt file using OpenBackupEventLog() and passing in a file name. 2. I then use ReadEventLog() to fill up a buffer with an unknown number of EventLog messages. 3. I traverse through the buffer and add each message to a vector 4. I keep filling up buffers (repeat steps 2 and 3) until I reach the end of the file. Here is my code for filling the vector: vector<PEVENTLOGRECORD> allRecords; while(_status == ERROR_SUCCESS) { if(!ReadEventLog(...)) CheckStatus(); else FillVectorFromBuffer(allRecords) } // Function FillVectorFromBuffer FillVectorFromBuffer(vector(PEVENTLOGRECORD) &allRecords) { int bytesExamined = 0; PBYTE pRecord = (PBYTE)_lpBuffer; // This is one of the params in ReadEventLog() while(bytesExamined < _pnBytesRead) // Another param from ReadEventLog { PEVENTLOGRECORD currentRecord = (PEVENTLOGRECORD)(pRecord); allRecords.push_back(currentRecord); pRecord += currentRecord->Length; bytesExamined += currentRecord->Length; } } Anyway, whenever I run this, it will get all the EventLogs in the file, and the vector will have everything I want it to. But as soon as this line: if(!ReadEventLog()) gets called and returns true (aka ReadEventLog() returns false), then every field in my vector gets set to zero. The vector will still contain the correct number of elements, it's just that all of the fields in the PEVENTLOGRECORD struct are now zero. Anyone with better debugging experience have any ideas? Thanks.

  • Dynamically creating subviews of similar type

    - by Akki
    My code for above view is: -(void)viewWillAppear:(BOOL)animated{ float yh = 0; while (yh<200) { //UIView CGRect myFrame = CGRectMake(0, yh, 320, 30); UIView *myFirstView = [[UIView alloc] initWithFrame:myFrame]; myFirstView.backgroundColor = [UIColor orangeColor]; //IUILabel in UIView CGRect mylblFrame = CGRectMake(5, yh, 60, 15); UILabel *lblsize = [[UILabel alloc] initWithFrame:mylblFrame]; lblsize.text = @"Hello"; [myFirstView addSubview:lblsize]; CGRect mylbl_hi = CGRectMake(80, yh, 60, 15); UILabel *lbl_hi = [[UILabel alloc] initWithFrame:mylbl_hi]; lbl_hi.text = @"Hii"; [myFirstView addSubview:lbl_hi]; [self.view addSubview:myFirstView]; [lbl_hi release]; [lblsize release]; [myFirstView release]; yh=yh+40; } [super viewWillAppear:YES]; } I can't understand reason of it being like this...i wanted labels to be attached with my subviews of orange color...this may be odd day for me to understand what's wrong with my code...if any of you can tell me where i ma doing wrong would be great to me. This is my first time creating view programmatically..so please excuse me if all this is silly question
