  • Event not bubbling in some Browsers when clicked on Flash

    - by 166_MMX
    Environment: Windows 7, Internet Explorer 8, Flash ActiveX 10.1.53.64, wmode=transparent Just wrote a small test page that you can load in IE and Firefox or any other Browser. <!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd"> <html xmlns="http://www.w3.org/1999/xhtml"> <head> <title>Event bubbling test</title> </head> <body onclick="alert('body');" style="margin:0;border-width:0;padding:0;background-color:#00FF00;"> <div onclick="alert('div');" style="margin:0;border-width:0;padding:0;background-color:#FF0000;"> <span onclick="alert('span');" style="margin:0;border-width:0;padding:0;background-color:#0000FF;"> <object classid="clsid:D27CDB6E-AE6D-11cf-96B8-444553540000" codebase="http://fpdownload.macromedia.com/get/shockwave/cabs/flash/swflash.cab#version=7,0,0,0" width="159" height="91" id="flashAbout_small" align="absmiddle"> <param name="movie" value="http://www.adobe.com/swf/software/flash/about/flashAbout_info_small.swf"/> <param name="quality" value="high"/> <param name="bgcolor" value="#FFFFFF"/> <param name="wmode" value="transparent"/> <embed src="http://www.adobe.com/swf/software/flash/about/flashAbout_info_small.swf" quality="high" bgcolor="#FFFFFF" width="159" height="91" wmode="transparent" name="flashAbout_small" align="absmiddle" type="application/x-shockwave-flash" pluginspage="http://www.adobe.com/go/getflashplayer"/> </object> </span> </div> </body> </html> So clicking any colored shape should produce an alert (except for the green one in IE, not sure why but I hope that's off topic and not related to my issue). Clicking the Flash container in Firefox will work Perfectly fine. You should get alert boxes in this order containing: span, div and body. Flash bubbles the event to the HTML. But this is not happening in IE. So why is Flash in IE not bubbling events to HTML? Edit: As mentioned by Andy E this behavior can also bee seen in Google Chrome which to my knowledge is not using ActiveX to embed the flash movie into the page.

  • When will the ValueConverter's Convert method be called in wpf

    - by sudarsanyes
    I have an ObservableCollection bound to a list box and a boolean property bound to a button. I then defined two converters, one that operates on the collection and the other operates on the boolean property. Whenever I modify the boolean property, the converter's Convert method is called, where as the same is not called if I modify the observable collection. What am I missing?? Snippets for your reference, xaml snipet, <Window.Resources> <local:WrapPanelWidthConverter x:Key="WrapPanelWidthConverter" /> <local:StateToColorConverter x:Key="StateToColorConverter" /> </Window.Resources> <StackPanel> <ListBox x:Name="NamesListBox" ItemsSource="{Binding Path=Names}"> <ListBox.ItemsPanel> <ItemsPanelTemplate> <WrapPanel x:Name="ItemWrapPanel" Width="500" Background="Gray"> <WrapPanel.RenderTransform> <TranslateTransform x:Name="WrapPanelTranslatation" X="0" /> </WrapPanel.RenderTransform> <WrapPanel.Triggers> <EventTrigger RoutedEvent="WrapPanel.Loaded"> <BeginStoryboard> <Storyboard> <DoubleAnimation Storyboard.TargetName="WrapPanelTranslatation" Storyboard.TargetProperty="X" To="{Binding Path=Names,Converter={StaticResource WrapPanelWidthConverter}}" From="525" Duration="0:0:2" RepeatBehavior="100" /> </Storyboard> </BeginStoryboard> </EventTrigger> </WrapPanel.Triggers> </WrapPanel> </ItemsPanelTemplate> </ListBox.ItemsPanel> <ListBox.ItemTemplate> <DataTemplate> <Grid> <Label Content="{Binding}" Width="50" Background="LightGray" /> </Grid> </DataTemplate> </ListBox.ItemTemplate> </ListBox> <Button Content="{Binding Path=State}" Background="{Binding Path=State, Converter={StaticResource StateToColorConverter}}" Width="100" Height="100" Click="Button_Click" /> </StackPanel> code behind snippet public class WrapPanelWidthConverter : IValueConverter { public object Convert(object value, Type targetType, object parameter, System.Globalization.CultureInfo culture) { ObservableCollection<string> aNames = value as ObservableCollection<string>; return -(aNames.Count * 50); } public object ConvertBack(object value, Type targetType, object parameter, System.Globalization.CultureInfo culture) { throw new NotImplementedException(); } } public class StateToColorConverter : IValueConverter { public object Convert(object value, Type targetType, object parameter, System.Globalization.CultureInfo culture) { bool aState = (bool)value; if (aState) return Brushes.Green; else return Brushes.Red; } public object ConvertBack(object value, Type targetType, object parameter, System.Globalization.CultureInfo culture) { throw new NotImplementedException(); } }

  • How to combine a relative top with an absolute bottom in CSS?

    - by ceving
    I need to define a div which must stay with the top at the normal position, which differs from the top of the surrounding element: position:relative top:0 and which grows in the height up to the size of the surrounding element: position:absolute bottom:0 I have no idea how to combine the both. Whenever I use a relative box I loose the absolute bottom and whenever I use an absolute box I loose the relative top. Can anybody help me how to do this in CSS? Here is an example: <html> <head> </head> <style type="text/css"> @media screen { body { position: absolute; top: 0; left: 0; right: 0; bottom: 0; margin: 0; padding: 0; } #head { background-color: gray; } #rel { background-color: green; position: relative; top: 0; bottom: 0; float: left; } #abs { background-color: red; position: absolute; top: 0; bottom: 0; float: left; } } </style> <body> <div id="head"> <h1>Head</h1> </div> <div id="abs"> <h2>absolute</h2> </div> <div id="rel"> <h2>relative</h2> </div> </body> </html> "relative" does not grow at all and "absolute" grows too much.

  • jquery - loading inline javascript via AJAX

    - by yaya3
    I have thrown together a quick prototype to try and establish a few very basic truths regarding what inline JavaScript can do when it is loaded with AJAX: index.html <html> <head> <script src="http://ajax.googleapis.com/ajax/libs/jquery/1/jquery.min.js"></script> </head> <body> <script type="text/javascript"> $('p').css('color','white'); alert($('p').css('color')); // DISPLAYS FIRST but is "undefined" $(document).ready(function(){ $('#ajax-loaded-content-wrapper').load('loaded-by-ajax.html', function(){ $('p').css('color','grey'); alert($('p').css('color')); // DISPLAYS LAST (as expected) }); $('p').css('color','purple'); alert($('p').css('color')); // DISPLAYS SECOND }); </script> <p>Content not loaded by ajax</p> <div id="ajax-loaded-content-wrapper"> </div> </body> </html> loaded-by-ajax.html <p>Some content loaded by ajax</p> <script type="text/javascript"> $('p').css('color','yellow'); alert($('p').css('color')); // DISPLAYS THIRD $(document).ready(function(){ $('p').css('color','pink'); alert($('p').css('color')); // DISPLAYS FOURTH }); </script> <p>Some content loaded by ajax</p> <script type="text/javascript"> $(document).ready(function(){ $('p').css('color','blue'); alert($('p').css('color')); // DISPLAYS FIFTH }); $('p').css('color','green'); alert($('p').css('color')); // DISPLAYS SIX </script> <p>Some content loaded by ajax</p> Notes: a) All of the above (except the first) successfully change the colour of all the paragraphs (in firefox 3.6.3). b) I've used alert instead of console.log as console is undefined when called in the 'loaded' HTML. Truths(?): $(document).ready() does not treat the 'loaded' HTML as a new document, or reread the entire DOM tree including the loaded HTML, it is pointless inside AJAX loaded content JavaScript that is contained inside 'loaded' HTML can effect the style of existing DOM nodes One can successfully use the jQuery library inside 'loaded' HTML to effect the style of existing DOM nodes One can not use the firebug inside 'loaded' HTML can effect the existing DOM (proven by Note a) Am I correct in deriving these 'truths' from my tests (test validity)? If not, how would you test for these?

  • Why does UIWebKit throw a structuralComplexityContribution exception?

    - by Axeva
    I've got a simple UIWebView in my iPhone app that's loading a XHTML document with some SGV embeded. This all works find on the desktop version of Safari, but it crashes in a UIWebView. Here is the Objective C: NSString *path = [[NSBundle mainBundle] pathForResource:@"test" ofType:@"html"]; NSData *fileData = [NSData dataWithContentsOfFile: path]; [svgView loadData: fileData MIMEType: @"text/xml" textEncodingName: @"UTF-8" baseURL: [NSURL fileURLWithPath: path]]; I also tried a MIMEType of application/xhtml+xml, but it didn't help. Here is the HTML: <!DOCTYPE html> <html xmlns="http://www.w3.org/1999/xhtml"> <head> <title>XTech SVG Demo</title> </head> <body> <svg xmlns="http://www.w3.org/2000/svg"> <g style="fill-opacity:0.7;"> <circle cx="6.5cm" cy="2cm" r="100" style="fill:red; stroke:black; stroke-width:0.1cm" transform="translate(0,50)" /> <circle cx="6.5cm" cy="2cm" r="100" style="fill:blue; stroke:black; stroke-width:0.1cm" transform="translate(70,150)" /> <circle cx="6.5cm" cy="2cm" r="100" style="fill:green; stroke:black; stroke-width:0.1cm" transform="translate(-70,150)"/> </g> </svg> </body> </html> All very basic stuff. When it loads on the iPhone, however, it crashes with this error: 2010-03-31 10:37:10.252 ColorDoodle[2014:20b] -[DOMElement structuralComplexityContribution]: unrecognized selector sent to instance 0x3e51b60 2010-03-31 10:37:10.253 ColorDoodle[2014:20b] Terminating app due to uncaught exception 'NSInvalidArgumentException', reason: ' -[DOMElement structuralComplexityContribution]: unrecognized selector sent to instance 0x3e51b60' Any idea why? Is this a bug in the rendering engine of the UIWebView? I don't see anything too odd here. * Updated * There is definitely something screwy going on here. If I add this bit of code just inside the tag, it works fine: <form> </form> Take that code back out, and it crashes again.

  • CSS to Replace Table Layout for Forms

    - by Erick
    I've looked at other questions and am unable to find the solution to this. Consider this image: I want to wrap divs and stack them vertically. The GREEN div would be a wrapper on a line. The BLUE div would contain an html label and maybe icon for a tooltip. The ORANGE div would contain some sort of entry (input, select, textarea). Several of these would be stacked vertically to make up a form. I am doing this now, but I have to specify a height for the container div and that really needs to change depending on the content - considering any entry could land there. Images and other stuff could land here, as well. I have a width set on the BLUE div and the ORANGE is float:left. How can I get rid of the height on divs and let that be determined by content? Is there a better way? Changing all to something else would be difficult and would prefer a way to style all elements or something. The code I'm using is like: <div class=EntLine> <div class=EntLbl> <label for="Name">Name</label> </div> <div class=EntFld> <input type=text id="Name" /> </div> </div> The CSS looks like: .EntLine { height: 20px; position: relative; margin-top: 2px; text-align: left; white-space: nowrap; } .EntLbl { float: left; width: 120px; padding: 3px 0px 0px 3px; min-width: 120px; max-width: 120px; vertical-align: text-top; } .EntFld { float: left; height: 20px; padding: 0px; width: 200px; } Thanks!

  • Junit (3.8.1) testing that an exception is thrown (works in unit test, fails when added to a testSui

    - by Mike Cargal
    I'm trying to test that I'm throwing an exception when appropriate. In my test class I have a method similar to the following: public void testParseException() { try { ClientEntitySingleton.getInstance(); fail("should have thrown exception."); } catch (RuntimeException re) { assertEquals( "<exception message>", re.getMessage()); } } This works fine (green bar) whenever I run that single unitTest class. However, when I add that test to a testSuite, I get a red bar Unit test failure reported on the exception. One more thing... it works in the testSuite, if it's the first test in the suite. Actually, I'm doing two of these tests and just figured out that if I make them the first two tests in the suite, all is good, but I get this failure if a "regular" test precedes it. So I have a work-around, but no real answer. Any ideas? Heres'a stack trace of the "failure" java.lang.RuntimeException: ProcEntity client dn="Xxxxxx/Xxxx/XXX" is defined multiple times. at com.someco.someprod.clientEntityManagement.ClientEntitySingleton.addClientEntity(ClientEntitySingleton.java:247) at com.someco.someprod.clientEntityManagement.ClientEntitySingleton.startElement(ClientEntitySingleton.java:264) at org.apache.xerces.parsers.AbstractSAXParser.startElement(Unknown Source) at org.apache.xerces.impl.XMLDocumentFragmentScannerImpl.scanStartElement(Unknown Source) at org.apache.xerces.impl.XMLDocumentFragmentScannerImpl$FragmentContentDispatcher.dispatch(Unknown Source) at org.apache.xerces.impl.XMLDocumentFragmentScannerImpl.scanDocument(Unknown Source) at org.apache.xerces.parsers.XML11Configuration.parse(Unknown Source) at org.apache.xerces.parsers.XML11Configuration.parse(Unknown Source) at org.apache.xerces.parsers.XMLParser.parse(Unknown Source) at org.apache.xerces.parsers.AbstractSAXParser.parse(Unknown Source) at com.someco.someprod.clientEntityManagement.ClientEntitySingleton.parse(ClientEntitySingleton.java:216) at com.someco.someprod.clientEntityManagement.ClientEntitySingleton.reload(ClientEntitySingleton.java:303) at com.someco.someprod.clientEntityManagement.ClientEntitySingleton.setInputSourceProvider(ClientEntitySingleton.java:88) at com.someco.someprod.clientEntityManagement.test.TestClientBase.setUp(TestClientBase.java:17) at com.someco.someprod.clientEntityManagement.test.TestClientEntityDup.setUp(TestClientEntityDup.java:8) at junit.framework.TestCase.runBare(TestCase.java:125) at junit.framework.TestResult$1.protect(TestResult.java:106) at junit.framework.TestResult.runProtected(TestResult.java:124) at junit.framework.TestResult.run(TestResult.java:109) at junit.framework.TestCase.run(TestCase.java:118) at junit.framework.TestSuite.runTest(TestSuite.java:208) at junit.framework.TestSuite.run(TestSuite.java:203) at junit.framework.TestSuite.runTest(TestSuite.java:208) at junit.framework.TestSuite.run(TestSuite.java:203) at org.eclipse.jdt.internal.junit.runner.junit3.JUnit3TestReference.run(JUnit3TestReference.java:128) at org.eclipse.jdt.internal.junit.runner.TestExecution.run(TestExecution.java:38) at org.eclipse.jdt.internal.junit.runner.RemoteTestRunner.runTests(RemoteTestRunner.java:460) at org.eclipse.jdt.internal.junit.runner.RemoteTestRunner.runTests(RemoteTestRunner.java:673) at org.eclipse.jdt.internal.junit.runner.RemoteTestRunner.run(RemoteTestRunner.java:386) at org.eclipse.jdt.internal.junit.runner.RemoteTestRunner.main(RemoteTestRunner.java:196)

  • when I click submit it should change the text and update the row something is wrong there

    - by Yousef Altaf
    good morning programers, I have this small code which content a news control panel and I made a submit button there to active or inactive the news row so if I click on this button it should change if it's active it will be inactive it worked but there's something wrong there when I click on item one it updates the last on the table not the first on as it should do. here is the code that I use <?php $getNewsData="select * from news"; $QgetNewsData=$db->query($getNewsData)or die($db->error); $count=mysqli_num_rows($QgetNewsData); while($newsRow = mysqli_fetch_array($QgetNewsData)) { $getActivityStatus=$newsRow['news_activity']; switch($getActivityStatus){ case 1: echo"<input style='color:red; font-weight:bold; background:none; border:0;' name='inactive' type='submit' value='?????' /><input name='inActive' type='hidden' value='".$newsRow['news_id']."'/>"; break; case 0: echo"<input style='color:green; font-weight:bold; background:none; border:0;' name='active' type='submit' value='?????' /><input name='Active' type='hidden' value='".$newsRow['news_id']."'/>"; break;} } if(isset($_POST['inactive'])){ $inActive=$_POST['inActive']; echo $inActive; $updateStatus="UPDATE news SET news_activity=0 WHERE news_id='".$inActive."'

  • Making a Grid in an NSView

    - by Hooligancat
    I currently have an NSView that draws a grid pattern (essentially a guide of horizontal and vertical lines) with the idea being that a user can change the spacing of the grid and the color of the grid. The purpose of the grid is to act as a guideline for the user when lining up objects. Everything works just fine with one exception. When I resize the NSWindow by dragging the resize handle, if my grid spacing is particularly small (say 10 pixels). the drag resize becomes lethargic in nature. My drawRect code for the grid is as follows: -(void)drawRect:(NSRect)dirtyRect { NSRect thisViewSize = [self bounds]; // Set the line color [[NSColor colorWithDeviceRed:0 green:(255/255.0) blue:(255/255.0) alpha:1] set]; // Draw the vertical lines first NSBezierPath * verticalLinePath = [NSBezierPath bezierPath]; int gridWidth = thisViewSize.size.width; int gridHeight = thisViewSize.size.height; int i; while (i < gridWidth) { i = i + [self currentSpacing]; NSPoint startPoint = {i,0}; NSPoint endPoint = {i, gridHeight}; [verticalLinePath setLineWidth:1]; [verticalLinePath moveToPoint:startPoint]; [verticalLinePath lineToPoint:endPoint]; [verticalLinePath stroke]; } // Draw the horizontal lines NSBezierPath * horizontalLinePath = [NSBezierPath bezierPath]; i = 0; while (i < gridHeight) { i = i + [self currentSpacing]; NSPoint startPoint = {0,i}; NSPoint endPoint = {gridWidth, i}; [horizontalLinePath setLineWidth:1]; [horizontalLinePath moveToPoint:startPoint]; [horizontalLinePath lineToPoint:endPoint]; [horizontalLinePath stroke]; } } I suspect this is entirely to do with the way that I am drawing the grid and am open to suggestions on how I might better go about it. I can see where the inefficiency is coming in, drag-resizing the NSWindow is constantly calling the drawRect in this view as it resizes, and the closer the grid, the more calculations per pixel drag of the parent window. I was thinking of hiding the view on the resize of the window, but it doesn't feel as dynamic. I want the user experience to be very smooth without any perceived delay or flickering. Does anyone have any ideas on a better or more efficient method to drawing the grid? All help, as always, very much appreciated.

  • .NET Impersonate and file upload issues

    - by Jagd
    I have a webpage that allows a user to upload a file to a network share. When I run the webpage locally (within VS 2008) and try to upload the file, it works! However, when I deploy the website to the webserver and try to upload the file through the webpage, it doesn't work! The error being returned to me on the webserver says "Access to the path '\05prd1\emp\test.txt' is denied. So, obviously, this is a permissions issue. The network share is configured to allow full access both to me (NT authentication) and to the NETWORK SERVICE (which is .NET's default account and what we have set in our IIS application pool as the default user for this website). I have tried this with and without impersonation upon the webserver and neither way works, yet both ways work on my local machine (in other words, with and without impersonation works on my local machine). The code that does the file upload is below. Please note that the code below includes impersonation, but like I said above, I've tried it with and without impersonation and it's made no difference. if (fuCourses.PostedFile != null && fuCourses.PostedFile.ContentLength > 0) { System.Security.Principal.WindowsImpersonationContext impCtx; impCtx = ((System.Security.Principal.WindowsIdentity)User.Identity).Impersonate(); try { lblMsg.Visible = true; // The courses file to be uploaded HttpPostedFile file = fuCourses.PostedFile; string fName = file.FileName; string uploadPath = "\\\\05prd1\\emp\\"; // Get the file name if (fName.Contains("\\")) { fName = fName.Substring( fName.LastIndexOf("\\") + 1); } // Delete the courses file if it is already on \\05prd1\emp FileInfo fi = new FileInfo(uploadPath + fName); if (fi != null && fi.Exists) { fi.Delete(); } // Open new file stream on \\05prd1\emp and read bytes into it from file upload FileStream fs = File.Create(uploadPath + fName, file.ContentLength); using (Stream stream = file.InputStream) { byte[] b = new byte[4096]; int read; while ((read = stream.Read(b, 0, b.Length)) > 0) { fs.Write(b, 0, read); } } fs.Close(); lblMsg.Text = "File Successfully Uploaded"; lblMsg.ForeColor = System.Drawing.Color.Green; } catch (Exception ex) { lblMsg.Text = ex.Message; lblMsg.ForeColor = System.Drawing.Color.Red; } finally { impCtx.Undo(); } } Any help on this would be very appreciated!

  • objective-c default init method for class?

    - by Alex
    Hello, I have two differing methods for initializing my objective-c class. One is the default, and one takes a configuration parameter. Now, I'm pretty green when it comes to objective-c, but I've implemented these methods and I'm wondering if there's a better (more correct/in good style) way to handle initialization than the way I have done it. Meaning, did I write these initialization functions in accordance with standards and good style? It just doesn't feel right to check for the existence of selfPtr and then return based on that. Below are my class header and implementation files. Also, if you spot anything else that is wrong or evil, please let me know. I am a C++/Javascript developer who is learning objective-c as hobby and would appreciate any tips that you could offer. #import <Cocoa/Cocoa.h> // class for raising events and parsing returned directives @interface awesome : NSObject { // silence is golden. Actually properties are golden. Hence this emptiness. } // properties @property (retain) SBJsonParser* parser; @property (retain) NSString* eventDomain; @property (retain) NSString* appid // constructors -(id) init; -(id) initWithAppId:(id) input; // destructor -(void) dealloc; @end #import "awesome.h" #import "JSON.h" @implementation awesome - (id) init { if (self = [super init]) { // if init is called directly, just pass nil to AppId contructor variant id selfPtr = [self initWithAppId:nil]; } if (selfPtr) { return selfPtr; } else { return self; } } - (id) initWithAppId:(id) input { if (self = [super init]) { if (input = nil) { input = [[NSString alloc] initWithString:@"a369x123"]; } [self setAppid:input]; [self setEventDomain:[[NSString alloc] initWithString:@"desktop"]]; } return self; } // property synthesis @synthesize parser; @synthesize appid; @synthesize eventDomain; // destructor - (void) dealloc { self.parser = nil; self.appid = nil; self.eventDomain = nil; [super dealloc]; } @end Thanks!

Please note that the code below includes impersonation, but like I said above, I've tried it with and without impersonation and it's made no difference. if (fuCourses.PostedFile != null && fuCourses.PostedFile.ContentLength > 0) { System.Security.Principal.WindowsImpersonationContext impCtx; impCtx = ((System.Security.Principal.WindowsIdentity)User.Identity).Impersonate(); try { lblMsg.Visible = true; // The courses file to be uploaded HttpPostedFile file = fuCourses.PostedFile; string fName = file.FileName; string uploadPath = "\\\\05prd1\\emp\\"; // Get the file name if (fName.Contains("\\")) { fName = fName.Substring( fName.LastIndexOf("\\") + 1); } // Delete the courses file if it is already on \\05prd1\emp FileInfo fi = new FileInfo(uploadPath + fName); if (fi != null && fi.Exists) { fi.Delete(); } // Open new file stream on \\05prd1\emp and read bytes into it from file upload FileStream fs = File.Create(uploadPath + fName, file.ContentLength); using (Stream stream = file.InputStream) { byte[] b = new byte[4096]; int read; while ((read = stream.Read(b, 0, b.Length)) > 0) { fs.Write(b, 0, read); } } fs.Close(); lblMsg.Text = "File Successfully Uploaded"; lblMsg.ForeColor = System.Drawing.Color.Green; } catch (Exception ex) { lblMsg.Text = ex.Message; lblMsg.ForeColor = System.Drawing.Color.Red; } finally { impCtx.Undo(); } } Any help on this would be very appreciated!

  • Multiple Graphics2D Objects

    - by Trizicus
    I have a Graphics object of JPanel and that is working fine: import java.awt.Color; import java.awt.Graphics; import java.awt.Graphics2D; import java.awt.geom.Rectangle2D; import javax.swing.JPanel; public class GraphicsTest extends JPanel { private Graphics2D g2d; private String state; private int x, y; @Override public void paintComponent(Graphics g) { super.paintComponent(g); g2d = (Graphics2D) g; g2d.setClip(0, 0, getWidth(), getHeight()); g2d.setColor(Color.BLACK); g2d.drawString("STATE: " + state, 5, 15); g2d.drawString("Mouse Position: " + x + ", " + y, 5, 30); g2d.setColor(Color.red); Rectangle2D r2d = new Rectangle2D.Double(x,y,10,10); g2d.draw(r2d); Test t = new Test(); super.add(t); repaint(); } public void setState(String state) { this.state = state; } public String getState() { return state; } public void setX(int x) { this.x = x; } public void setY(int y) { this.y = y; } } I was experimenting with a new Graphics component and when I instantiate a new Test and add it in GraphicsTest nothing happens.

  • Insertions into Zipper trees on XML files in Clojure

    - by ivar
    I'm confused as how to idiomatically change a xml tree accessed through clojure.contrib's zip-filter.xml. Should be trying to do this at all, or is there a better way? Say that I have some dummy xml file "itemdb.xml" like this: <itemlist> <item id="1"> <name>John</name> <desc>Works near here.</desc> </item> <item id="2"> <name>Sally</name> <desc>Owner of pet store.</desc> </item> </itemlist> And I have some code: (require '[clojure.zip :as zip] '[clojure.contrib.duck-streams :as ds] '[clojure.contrib.lazy-xml :as lxml] '[clojure.contrib.zip-filter.xml :as zf]) (def db (ref (zip/xml-zip (lxml/parse-trim (java.io.File. "itemdb.xml"))))) ;; Test that we can traverse and parse. (doall (map #(print (format "%10s: %s\n" (apply str (zf/xml-> % :name zf/text)) (apply str (zf/xml-> % :desc zf/text)))) (zf/xml-> @db :item))) ;; I assume something like this is needed to make the xml tags (defn create-item [name desc] {:tag :item :attrs {:id "3"} :contents (list {:tag :name :attrs {} :contents (list name)} {:tag :desc :attrs {} :contents (list desc)})}) (def fred-item (create-item "Fred" "Green-haired astrophysicist.")) ;; This disturbs the structure somehow (defn append-item [xmldb item] (zip/insert-right (-> xmldb zip/down zip/rightmost) item)) ;; I want to do something more like this (defn append-item2 [xmldb item] (zip/insert-right (zip/rightmost (zf/xml-> xmldb :item)) item)) (dosync (alter db append-item2 fred-item)) ;; Save this simple xml file with some added stuff. (ds/spit "appended-itemdb.xml" (with-out-str (lxml/emit (zip/root @db) :pad true))) I am unclear about how to use the clojure.zip functions appropriately in this case, and how that interacts with zip-filter. If you spot anything particularly weird in this small example, please point it out.

  • php , SimpleXML, while loop

    - by Michael
    I'm trying to get some information from ebay api and store it in database . I used simple xml to extract the information but I have a small issue as the information is not displayed for some items . if I make a print to the simple_xml I can see very well that the information is provided by ebay api . I have $items = "220617293997,250645537939,230485306218,110537213815,180519294810"; $number_of_items = count(explode(",", $items)); $xml = $baseClass->getContent("http://open.api.ebay.com/shopping?callname=GetMultipleItems&responseencoding=XML&appid=Morcovar-c74b-47c0-954f-463afb69a4b3&siteid=0&version=525&IncludeSelector=ItemSpecifics&ItemID=$items"); writeDoc($xml, "api.xml"); //echo $xml; $getvalues = simplexml_load_file('api.xml'); // print_r($getvalue); $number = "0"; while($number < 6) { $item_number = $getvalues->Item[$number]->ItemID; $location = $getvalues->Item[$number]->Location; $title = $getvalues->Item[$number]->Title; $price = $getvalues->Item[$number]->ConvertedCurrentPrice; $manufacturer = $getvalues->Item[$number]->ItemSpecifics->NameValueList[3]->Value; $model = $getvalues->Item[$number]->ItemSpecifics->NameValueList[4]->Value; $mileage = $getvalues->Item[$number]->ItemSpecifics->NameValueList[5]->Value; echo "item number = $item_number <br>localtion = $location<br>". "title = $title<br>price = $price<br>manufacturer = $manufacturer". "<br>model = $model<br>mileage = $mileage<br>"; $number++; } the above code returns item number = localtion = title = price = manufacturer = model = mileage = item number = 230485306218 localtion = Coventry, Warwickshire title = 2001 LAND ROVER RANGE ROVER VOGUE AUTO GREEN price = 3635.07 manufacturer = Land Rover model = Range Rover mileage = 76000 item number = 220617293997 localtion = Crawley, West Sussex title = 2004 CITROEN C5 HDI LX RED price = 3115.77 manufacturer = Citroen model = C5 mileage = 76000 item number = 180519294810 localtion = London, London title = 2000 VOLKSWAGEN POLO 1.4 SILVER 16V NEED GEAR BOX price = 905.06 manufacturer = Right-hand drive model = mileage = Standard Car item number = localtion = title = price = manufacturer = model = mileage = As you can see the information is not retrieved for a few items ... If I replace the $number manually like " $item_number = $getvalues-Item[4]-ItemID;" works well for any number .

  • How can I fix this NavigationController and UIToolbar offset issue in Objective-C?

    - by editor
    I'm adding a couple of buttons to an already-existing NavigationController. The two buttons are added to a UIView, which is pushed onto the NavigationItem. The buttons stop and reload a UIWebView. Problem is that there's a slight offset issue that is making it all look pretty ugly. I wish I could set the UIToolbar to transparent or clear background but that doesn't seem to be an option. Can't seem to use negative offsets either. I've got color matching, but if you look closely there's 1px or 2px of highlighting up top that's causing a visual mismatch and then a slight offset at the bottom. Some relevant code below (based on this, inbound Googlers). What are my options to resolve this? // create a toolbar for the buttons UIToolbar* toolbar = [[UIToolbar alloc] initWithFrame:CGRectMake(0, 0, 100, 45)]; [toolbar setBarStyle: UIBarStyleDefault]; UIColor *colorForBar = [[UIColor alloc] initWithRed:.72 green:0 blue:0 alpha:0]; toolbar.tintColor = colorForBar; [colorForBar release]; //[toolbar setTranslucent:YES]; // create an array for the buttons NSMutableArray* buttons = [[NSMutableArray alloc] initWithCapacity:3]; // create a standard reload button UIBarButtonItem *reloadButton = [[UIBarButtonItem alloc] initWithBarButtonSystemItem:UIBarButtonSystemItemRefresh target:self action:@selector(reload)]; reloadButton.style = UIBarButtonItemStyleBordered; [buttons addObject:reloadButton]; [reloadButton release]; // create a spacer between the buttons UIBarButtonItem *spacer = [[UIBarButtonItem alloc] initWithBarButtonSystemItem:UIBarButtonSystemItemFixedSpace target:nil action:nil]; [buttons addObject:spacer]; [spacer release]; // create a standard delete button with the trash icon UIBarButtonItem *stopButton = [[UIBarButtonItem alloc] initWithBarButtonSystemItem:UIBarButtonSystemItemStop target:self action:@selector(stopLoading)]; stopButton.style = UIBarButtonItemStyleBordered; [buttons addObject:stopButton]; [stopButton release]; // put the buttons in the toolbar and release them [toolbar setItems:buttons animated:NO]; [buttons release]; // place the toolbar into the navigation bar self.navigationItem.rightBarButtonItem = [[UIBarButtonItem alloc] initWithCustomView:toolbar]; [toolbar release];

  • How to show percentage of 'memory used' in a win32 process?

    - by pj4533
    I know that memory usage is a very complex issue on Windows. I am trying to write a UI control for a large application that shows a 'percentage of memory used' number, in order to give the user an indication that it may be time to clear up some memory, or more likely restart the application. One implementation used ullAvailVirtual from MEMORYSTATUSEX as a base, then used HeapWalk() to walk the process heap looking for additional free memory. The HeapWalk() step was needed because we noticed that after a while of running the memory allocated and freed by the heap was never returned and reported by the ullAvailVirtual number. After hours of intensive working, the ullAvailVirtual number no longer would accurately report the amount of memory available. However, this method proved not ideal, due to occasional odd errors that HeapWalk() would return, even when the process heap was not corrupted. Further, since this is a UI control, the heap walking code was executing every 5-10 seconds. I tried contacting Microsoft about why HeapWalk() was failing, escalated a case via MSDN, but never got an answer other than "you probably shouldn't do that". So, as a second implementation, I used PagefileUsage from PROCESS_MEMORY_COUNTERS as a base. Then I used VirtualQueryEx to walk the virtual address space adding up all regions that weren't MEM_FREE and returned a value for GetMappedFileNameA(). My thinking was that the PageFileUsage was essentially 'private bytes' so if I added to that value the total size of the DLLs my process was using, it would be a good approximation of the amount of memory my process was using. This second method seems to (sorta) work, at least it doesn't cause crashes like the heap walker method. However, when both methods are enabled, the values are not the same. So one of the methods is wrong. So, StackOverflow world...how would you implement this? which method is more promising, or do you have a third, better method? should I go back to the original method, and further debug the odd errors? should I stay away from walking the heap every 5-10 seconds? Keep in mind the whole point is to indicate to the user that it is getting 'dangerous', and they should either free up memory or restart the application. Perhaps a 'percentage used' isn't the best solution to this problem? What is? Another idea I had was a color based system (red, yellow, green, which I could base on more factors than just a single number)

  • Dragging a div along with all of its child divs

I can drag individual divs, but that is not what I want. Can a div drag child divs or do they have to be images? I am using the WalterZorn drag drop API, but am open to using any API, script or whatever.

  • SET game odds simulation (MATLAB)

    - by yuk
    Here is an interesting problem for your weekend. :) I recently find the great card came - SET. Briefly, there are 81 cards with the four features: symbol (oval, squiggle or diamond), color (red, purple or green), number (one, two or three) or shading (solid, striped or open). The task is to find (from selected 12 cards) a SET of 3 cards, in which each of the four features is either all the same on each card or all different on each card (no 2+1 combination). In my free time I've decided to code it in MATLAB to find a solution and to estimate odds of having a set in randomly selected cards. Here is the code: %% initialization K = 12; % cards to draw NF = 4; % number of features (usually 3 or 4) setallcards = unique(nchoosek(repmat(1:3,1,NF),NF),'rows'); % all cards: rows - cards, columns - features setallcomb = nchoosek(1:K,3); % index of all combinations of K cards by 3 %% test tic NIter=1e2; % number of test iterations setexists = 0; % test results holder % C = progress('init'); % if you have progress function from FileExchange for d = 1:NIter % C = progress(C,d/NIter); % cards for current test setdrawncardidx = randi(size(setallcards,1),K,1); setdrawncards = setallcards(setdrawncardidx,:); % find all sets in current test iteration for setcombidx = 1:size(setallcomb,1) setcomb = setdrawncards(setallcomb(setcombidx,:),:); if all(arrayfun(@(x) numel(unique(setcomb(:,x))), 1:NF)~=2) % test one combination setexists = setexists + 1; break % to find only the first set end end end fprintf('Set:NoSet = %g:%g = %g:1\n', setexists, NIter-setexists, setexists/(NIter-setexists)) toc 100-1000 iterations are fast, but be careful with more. One million iterations takes about 15 hours on my home computer. Anyway, with 12 cards and 4 features I've got around 13:1 of having a set. This is actually a problem. The instruction book said this number should be 33:1. And it was recently confirmed by Peter Norvig. He provides the Python code, but I didn't test it. So can you find an error?

  • iphone cocos2d sprites disappearing

    - by jer
    I've been working on a game and implementing the physics stuff with chipmunk. All was going fine on the cocos2d part until the integration with chipmunk. A bit of background: The game is a game with blocks. Levels are defined in a property list, where positions, size of the blocks, gravitational forces, etc., are all defined for each block to be shown in the level. The problem is with the blocks showing up. I have a method on my BlockLayer class which is part of my game's main scene. Upon creation of the layer, the property list is read, and all the blocks are created. The following method is called to create the blocks: - (void)createBlock:(Block*)block withAssets:(NSBundle*)assets { Sprite* sprite; switch(block.blockColour) { case kBlockColourGreen: sprite = [Sprite spriteWithFile:[assets pathForResource:@"green" ofType:@"png" inDirectory:@"Blocks"]]; break; case kBlockColourOrange: sprite = [Sprite spriteWithFile:[assets pathForResource:@"orange" ofType:@"png" inDirectory:@"Blocks"]]; break; case kBlockColourRed: sprite = [Sprite spriteWithFile:[assets pathForResource:@"red" ofType:@"png" inDirectory:@"Blocks"]]; break; case kBlockColourBlue: sprite = [Sprite spriteWithFile:[assets pathForResource:@"blue" ofType:@"png" inDirectory:@"Blocks"]]; break; } sprite.position = block.bounds.origin; [self addChild:sprite]; if(block.blockColour == kBlockColourGreen || block.blockColour == kBlockColourRed) space-gravity = cpvmult(cpv(0, 10), 1000); cpVect verts[] = { cpv(-block.bounds.size.width, -block.bounds.size.height), cpv(-block.bounds.size.width, block.bounds.size.height), cpv(block.bounds.size.width, block.bounds.size.height), cpv(block.bounds.size.width, -block.bounds.size.height) }; cpBody* blockBody = cpBodyNew([block.mass floatValue], INFINITY); blockBody-p = cpv(block.bounds.origin.x, block.bounds.origin.y); blockBody-v = cpvzero; cpSpaceAddBody(space, blockBody); cpShape* blockShape = cpPolyShapeNew(blockBody, 4, verts, cpvzero); blockShape-e = 0.9f; blockShape-u = 0.9f; blockShape-data = sprite; cpSpaceAddShape(space, blockShape); } With the above code, the sprites never show up. However, if I comment out the "cpSpaceAddBody(space, blockBody);" line, the sprites show up. The position and size of the blocks are stored in the "bounds" property of instances of the Block class, which is a CGRect. Not sure if it's important, but the orientation of the app is in landscape left, and all the coordinates are based on that orientation. Any help would be greatly appreciated.
