• Image not showing in UIImageView in Interface Builder / iPhone

  - by dbonneville

  I have a UIView with an UIImageView dragged onto the view. All of a sudden, for all my xibs, the image no longer shows up. There is a blue X. However, when it builds, the image is there. At one point, I deleted and regenerated all my images and moved some into a subfolder in XCode. Normally, when you go to select an image for an UIImageView, IB allows you to pick from any image in the project. But, I can't see any of the images I had put in the folder anymore in the dropdown. All I see in the dropdown on the Inspector is the one image I want, but that is also the one that is not showing up. And like I said, if I build it on the device or simulator, it all works. There is some cache or something screwed up somewhere. Everything builds with no errors. I cleared the caches and rebuilt. It all works. No error or warnings. But...I can't see any other images and IB still thinks it's missing the image that is clearly selected in the dropdown. So how do I get XCode and IB back on track and see what assets it properly should be seeing in the XIBs?

• xcode UIWebView - Text Fields = No on screen keyboard.

  - by Aakburns

  This application is used to let you use our company basecamp site and only that site. When logged in, if you go to post a new message, you can insert text in the title text field, but if you try to tap in the message body section, it does not bring up the keyboard. I have to assume it's something with my coding, because safari works just fine with it. You can pick textile/html mode or easy. The keyboard does come up in textile/html mode but not in easy formatting mode. Any ideas? Here are some screenshot examples from the iPad. This is shown as the text view not working, no keyboard comes up when you tap in the box. arikburnsDOTcom/forums/fn/IMG_0007.png If you click on 'Switch to Textile/HTML' As seen in the image above, you are presented with this new text box which you can tap in and the keyboard comes up. arikburnsDOTcom/forums/fn/IMG_0006.PNG Now, also note, if you load this same page up in safari, it doesn't actually give you an option as to what text formatting to use, it just works. No options. I basically need to force the 'Textile/HTML' text box somehow and no I cannot change the website code itself. Thanks in advance.

• FLEX: videoDisplay.addEventListener(VideoEvent.PLAYHEAD_UPDATE) doesn't work

  - by Patrick

  hi, the PLAYHEAD_UPDATE event is not triggered by my videoDisplay component in Flex. If I add the attribute playheadUpdate="playUpdate()" everything works fine. But in the following code, the method "playUpdate()" is not triggered... thanks <?xml version="1.0" encoding="utf-8"?> <mx:Application xmlns:mx="http://www.adobe.com/2006/mxml" layout="vertical" creationComplete="init()"> <mx:Script><![CDATA[ import mx.events.VideoEvent private function init():void { ... videoD.addEventListener(VideoEvent.PLAYHEAD_UPDATE, playUpdate); } private function thumbPressed():void { videoD.removeEventListener(VideoEvent.PLAYHEAD_UPDATE, playUpdate); } private function thumbReleased():void { videoD.addEventListener(VideoEvent.PLAYHEAD_UPDATE, playUpdate); } private function playUpdate():void { debugF.text = "OK"; slider.value = videoD.playheadTime; } ]]></mx:Script> <mx:VideoDisplay id="videoD" autoPlay="{autoPlayOption}" source="{videoPath}" click="togglePlay()" /> The text OK is not displayed, and the slider is not updated. As I mentioned before, adding the attribute in MXML, works, instead.

• Perf: Viewing thousands of images in Silverlight 3 on a 3D Wall

  - by Bob Holland

  I currently work on a very cool Silverlight app that displays photos in a 3D wall space like the Wall3D demo that is thrown in with Blend 3. The problem I am currently facing is performance. The app works like this: As you scroll right or left the 3d photo wall rotates As each movement is made, the next column of photos are downloaded, decoded into a BitmapImage and thrown into a 3D Wall Node. As you can imagine users (if you let them) will want to flip through the photos really quickly, but the problem I have is I cannot display the photos quick enough. In most cases it's a beautiful app that works really well, but when an album contains over 300 photos, you can imagine the sort of memory taken up by all the BitmapImage classes and how moving the slider can jump from photo 20 to photo 120 in a second. Of course we have algorithms in place to not download every photo in between, but I still can't work out a fast way to get the photos displayed. It may be a case that we need to throw away the 'great for show' 3D wall and go to a flat DeepZoom like wall like the Playboy archive one that Vertigo did. Still not sure, let me know your thoughts. P.S. We are using Kit3D for all the 3D work, it's using PerspectiveCamera, Model3DGroup, ModelVisual3D, RotateTransform3D & TranslateTransform3D. Cheers, Bob.

• NSURLConnection sendSynchronousRequest: fails when using POST

  - by Combat

  I'm using a custom NSURLCache to intercept calls for certain web pages in order to modify them dynamically. Inside cachedResponseForRequest: I modify the request, then send it out using sendSynchronousRequest. This works very well until you attempt to submit a form. If there is post data it fails. If i remove the HTTPBody and set the request to GET, it succeeds. But i need it to work with POST. If i send the request asynchronously it also works which is why i can't figure out why the synchronous request fails. Here's my stack trace: Date/Time: 2010-01-17 12:37:55.416 -0800 OS Version: iPhone OS 3.1.2 (7D11) Report Version: 104 Exception Type: EXC_BAD_ACCESS (SIGBUS) Exception Codes: KERN_PROTECTION_FAILURE at 0x0000001c Crashed Thread: 2 Thread 2 Crashed: 0 CFNetwork 0x0000b4e4 HTTPMessage::copyHeaderFieldValue(__CFString const*) + 18 1 CFNetwork 0x0000b4c8 CFHTTPMessageCopyHeaderFieldValue + 16 2 CFNetwork 0x0000e022 HTTPProtocol::createStream() + 328 3 CFNetwork 0x0000de8a HTTPProtocol::createAndOpenStream() + 458 4 CFNetwork 0x0000cba2 HTTPProtocol::startLoad() + 278 5 CFNetwork 0x0000c8da URLConnectionLoader::loaderScheduleOriginLoad(_CFURLRequest const*) + 216 6 CFNetwork 0x0000c77c URLConnectionLoader::loaderScheduleLoad(_CFURLRequest const*) + 280 7 CFNetwork 0x0000c5e6 URLConnectionLoader::LoaderConnectionEventQueue::processAllEventsAndConsumePayload(XConnectionEventInfo, long) + 134 8 CFNetwork 0x0000c53a URLConnectionLoader::processEvents() + 60 9 CFNetwork 0x0000a892 URLConnection::multiplexerClientPerform(RunLoopMultiplexer) + 30 10 CFNetwork 0x0000a812 MultiplexerSource::perform() + 86 11 CFNetwork 0x0000a7b2 MultiplexerSource::_perform(void*) + 2 12 CoreFoundation 0x000573a0 CFRunLoopRunSpecific + 1908 13 CoreFoundation 0x00056c18 CFRunLoopRunInMode + 44 14 Foundation 0x0005a998 +[NSURLConnection(NSURLConnectionReallyInternal) _resourceLoadLoop:] + 172 15 Foundation 0x00053ac6 -[NSThread main] + 42 16 Foundation 0x00001d0e __NSThread_main_ + 852 17 libSystem.B.dylib 0x0002b7b0 _pthread_body + 20 As you can see, copyHeaderFieldValue is causing the crash.

• asp.net mvc compress stream and remove whitespace

  - by Bigfellahull

  Hi, So I am compressing my output stream via an action filter: var response = filterContext.HttpContext.Response; response.Filter = new DeflateStream(response.Filter), CompressionMode.Compress); Which works great. Now, I would also like to remove the excess whitespace present. I found Mads Kristensen's http module http://madskristensen.net/post/A-whitespace-removal-HTTP-module-for-ASPNET-20.aspx. I added the WhitespaceFilter class and added a new filter like the compression: var response = filterContext.HttpContext.Response; response.Filter = new WhitepaperFilter(response.Filter); This also works great. However, I seem to be having problems combining the two! I tried: var response = filterContext.HttpContext.Response; response.Filter = new DeflateStream(new WhitespaceFilter(response.Filter), CompressionMode.Compress); However this results in some major issues. The html gets completely messed up and sometimes I get an 330 error. It seems that the Whitespace filter write method gets called multiple times. The first time the html string is fine, but on subsequent calls its just random characters. I thought it might be because the stream had been deflated, but isnt the whitespace filter using the untouched stream and then passing the resulting stream to the DeflateStream call? Any ideas?

• C# PrintPreviewDialog Modification possible?

  - by C. Griffin

  Currently, what I'm doing is this: Using the built-in .NET PrintPreviewDialog Attaching my own Click handler to the Print button, which allows for the user to select the printer before finally printing. This all WORKS, HOWEVER, the OnprintToolStripButtonClick event is still sending the document to the default printer BEFORE the user gets to choose the actual printer and click Print (which works, but they're getting an extra copy on the default printer first from the old Handler). Can I remove this built-in Click handler? I've tried the other methods mentioned on here in regards to using an EventHandlerList to remove the handlers, but it doesn't work for the built-in printing event. Here is a copy of my current code in case it helps clarify: // ... Irrelevant code before this private PrintPreviewDialog ppdlg; ToolStrip ts = new ToolStrip(); ts.Name = "wrongToolStrip"; foreach (Control ctl in ppdlg.Controls) { if (ctl.Name.Equals("toolStrip1")) { ts = ctl as ToolStrip; break; } } ToolStripButton printButton = new ToolStripButton(); foreach (ToolStripItem tsi in ts.Items) { if (tsi.Name.Equals("printToolStripButton")) { printButton = tsi as ToolStripButton; } } printButton.Click += new EventHandler(this.SelectPrinterAfterPreview); // ... Irrelevant code afterwards omitted // Here is the Handler for choosing a Printer that gets called after the // PrintPreviewDialog's "Print" button is clicked. private void SelectPrinterAfterPreview(object sender, EventArgs e) { frmMainPage frmMain = (frmMainPage)this.MdiParent; if (frmMain.printDialog1.ShowDialog() == DialogResult.OK) { pd.PrinterSettings.PrinterName = frmMain.printDialog1.PrinterSettings.PrinterName; pd.PrinterSettings.Copies = frmMain.printDialog1.PrinterSettings.Copies; pd.Print(); } }

• Problem binding action parameters using FCKeditor, AJAX and ASP.NET MVC

  - by TonE

  I have a simple ASP.Net MVC View which contains an FCKeditor text box (created using FCKeditor's Javascript ReplaceTextArea() function). These are included within an Ajax.BeginForm helper: <% using (Ajax.BeginForm("AddText", "Letters", new AjaxOptions() { UpdateTargetId = "addTextResult" })) {%> <div> <input type="submit" value="Save" /> </div> <div> <%=Html.TextArea("testBox", "Content", new { @name = "testBox" })%> <script type=""text/javascript""> window.onload = function() { var oFCKeditor = new FCKeditor('testBox') ; var sBasePath = '<%= Url.Content("~/Content/FCKeditor/") %>'; oFCKeditor.BasePath = sBasePath; oFCKeditor.ToolbarSet = "Basic"; oFCKeditor.Height = 400; oFCKeditor.ReplaceTextarea() ; } </script> <div id="addTextResult"> </div> <%} %> The controller action hanlding this is: [ValidateInput(false)] public ActionResult AddText(string testBox) { return Content(testBox); } Upon initial submission of the Ajax Form the testBox string in the AddText action is always "Content", whatever the contents of the FCKeditor have been changed to. If the Ajax form is submitted again a second time (without further changes) the testBox paramater correctly contains the actual contents of the FCKeditor. If I use a Html.TextArea without replacing with FCKeditor it works correctly, and if I use a standard Post form submit inplace of AJAX all works as expected. Am I doing something wrong? If not is there a suitable/straight-forward workaround for this problem?

• expected identity upn connecting to service as network service,

  - by Jim

  Hi, We have a web application, running in an application pool as 'NETWORK SERVICE'. The web application connects to a service (.svc) on another web server. The other web server also has the service hosted as 'NETWORK SERVICE'. I believe this is the default. The following endpoint, when run anywhere else works perfectly. <endpoint address="http://server123/UnitTrustService/UnitTrustService.svc" binding="wsHttpBinding" bindingConfiguration="WSHttpBinding_UnitTrustService" contract="UnitTrustServiceReference.UnitTrustService" name="WSHttpBinding_UnitTrustService"> <identity> <servicePrincipalName value="server123" /> </identity> </endpoint> Unfortunately when executed from the web site, we get the following error. System.ServiceModel.Security.MessageSecurityException: The identity check failed for the outgoing message. The expected identity is 'identity(http://schemas.xmlsoap.org/ws/2005/05/identity/right/possessproperty: http://schemas.xmlsoap.org/ws/2005/05/identity/claims/upn)' for the 'http://server123/UnitTrustService/UnitTrustService.svc' target endpoint. Server stack trace: at System.ServiceModel.Security.IdentityVerifier.EnsureIdentity(EndpointAddress serviceReference, AuthorizationContext authorizationContext, String errorString)... Any ideas? I have tried running this as local system on the web server machine with exactly the same configuration and it works perfectly. It has something to do with IIS? Regards Craig.

• Custom activity in WF 4.0: WorkflowItemsPresenter wont show converted array

  - by lotusnote

  Hi There, we have an Array which is converted via a Binded Converter: else if (TTools.IsOfBaseClass(value.GetType(), typeof(System.Activities.Presentation.Model.ModelItemCollection))) { OurBaseClass[] test = (value as ModelItemCollection).GetCurrentValue() as OurBaseClass[]; List<OurBaseClass> listOfArray = new List<OurBaseClass>(); foreach (OurBaseClass item in test) { listOfArray.Add(item); } return listOfArray; } the convertion works well but it is not shown in our dynamically gui gui code with bindings: <sap:WorkflowItemsPresenter xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation" xmlns:sap="clr-namespace:System.Activities.Presentation;assembly=System.Activities.Presentation" Grid.Column="0" Name="MyArray" Items="{Binding Path=ModelItem.MyArray}" MinWidth="150" Margin="0"> <sap:WorkflowItemsPresenter.SpacerTemplate > <DataTemplate> <TextBlock Foreground="DarkGray" Margin="30">..</TextBlock> </DataTemplate> </sap:WorkflowItemsPresenter.SpacerTemplate> <sap:WorkflowItemsPresenter.ItemsPanel> <ItemsPanelTemplate> <StackPanel Orientation="Vertical" HorizontalAlignment="Center" Margin="0"/> </ItemsPanelTemplate> </sap:WorkflowItemsPresenter.ItemsPanel> </sap:WorkflowItemsPresenter> Why is the gui not shown as a List??? it works well without converter.

• C# Design How to Elegantly wrap a DAL class

  - by guazz

  I have an application which uses MyGeneration's dOODads ORM to generate it's Data Access Layer. dOODad works by generating a persistance class for each table in the database. It works like so: // Load and Save Employees emps = new Employees(); if(emps.LoadByPrimaryKey(42)) { emps.LastName = "Just Got Married"; emps.Save(); } // Add a new record Employees emps = new Employees(); emps.AddNew(); emps.FirstName = "Mr."; emps.LastName = "dOOdad"; emps.Save(); // After save the identity column is already here for me. int i = emps.EmployeeID; // Dynamic Query - All Employees with 'A' in thier last name Employees emps = new Employees(); emps.Where.LastName.Value = "%A%"; emps.Where.LastName.Operator = WhereParameter.Operand.Like; emps.Query.Load(); For the above example(i.e. Employees DAL object) I would like to know what is the best method/technique to abstract some of the implementation details on my classes. I don't believe that an Employee class should have Employees(the DAL) specifics in its methods - or perhaps this is acceptable? Is it possible to implement some form of repository pattern? Bear in mind that this is a high volume, perfomacne critical application. Thanks, j

• Set margins in a LinearLayout programmatically.

  - by Timmmm

  I'm trying to use Java (not XML) to create a LinearLayout with buttons that fill the screen, and have margins. Here is code that works without margins: LinearLayout buttonsView = new LinearLayout(this); buttonsView.setOrientation(LinearLayout.VERTICAL); for (int r = 0; r < 6; ++r) { Button btn = new Button(this); btn.setText("A"); LinearLayout.LayoutParams lp = new LinearLayout.LayoutParams(LinearLayout.LayoutParams.FILL_PARENT, LinearLayout.LayoutParams.FILL_PARENT); // Verbose! lp.weight = 1.0f; // This is critical. Doesn't work without it. buttonsView.addView(btn, lp); } ViewGroup.LayoutParams lp = new ViewGroup.LayoutParams(ViewGroup.LayoutParams.FILL_PARENT, ViewGroup.LayoutParams.FILL_PARENT); setContentView(buttonsView, lp); So that works fine, but how on earth do you give the buttons margins so there is space between them? I tried using LinearLayout.MarginLayoutParams, but that has no weight member so it's no good. And it doesn't work if you pass it lp in its constructor either. Is this impossible? Because it sure looks it, and it wouldn't be the first Android layout task you can only do in XML.

• How to create a UIScrollView Programmatically?

  - by Wayfarer

  Alright, so the key here is I'm not using IB at all, because the View I'm working with is created programmatically. The UIView covers the lower half the screen, and has a bunch of buttons on it. However, I want to add more buttons to the UIView, without making it any larger. To do so, I want to make a UIScrollView inside the view, which will allow me to add more buttons off screen so the user can scroll to them. I think that's how it works. self.manaView = [[[UIView alloc] initWithFrame:frame] autorelease]; self.manaView.backgroundColor = [UIColor purpleColor]; UIScrollView *scroll = [UIScrollView alloc]; scroll.contentSize = CGSizeMake(320, 400); scroll.showsHorizontalScrollIndicator = YES; [self.manaView addSubview:scroll]; The first part of the code iniates my UIView, which works great, but I can't figure out how to make the UIScrollView programmatically and add it to the view, and then add the buttons to it. UIButton *ret2 = [UIButton buttonWithType:UIButtonTypeRoundedRect]; ret2.tag = 102; ret2.frame = CGRectMake(255, 5, 60, 50); [ret2 setTitle:@"Return" forState:UIControlStateNormal]; [ret2 addTarget:self action:@selector(flipAction:) forControlEvents:UIControlEventTouchUpInside]; [scroll addSubview:ret2]; When I did that, the button simply disappeared off my screen. So How do I do this correctly? Thank you for your help!

• StackOverflow in compojure web project

  - by Anders Rune Jensen

  Hi I've been playing around with clojure and have been using it to build a simple little audio player. The strange thing is that sometimes, maybe one out of twenty, when contact the server I will get the following error: 2010-04-20 15:33:20.963::WARN: Error for /control java.lang.StackOverflowError at clojure.lang.RT.seq(RT.java:440) at clojure.core$seq__4245.invoke(core.clj:105) at clojure.core$filter__5084$fn__5086.invoke(core.clj:1794) at clojure.lang.LazySeq.sval(LazySeq.java:42) at clojure.lang.LazySeq.seq(LazySeq.java:56) at clojure.lang.RT.seq(RT.java:440) at clojure.core$seq__4245.invoke(core.clj:105) at clojure.core$filter__5084$fn__5086.invoke(core.clj:1794) at clojure.lang.LazySeq.sval(LazySeq.java:42) at clojure.lang.LazySeq.seq(LazySeq.java:56) at clojure.lang.RT.seq(RT.java:440) at clojure.core$seq__4245.invoke(core.clj:105) at clojure.core$filter__5084$fn__5086.invoke(core.clj:1794) at clojure.lang.LazySeq.sval(LazySeq.java:42) at clojure.lang.LazySeq.seq(LazySeq.java:56) at clojure.lang.RT.seq(RT.java:440) at clojure.core$seq__4245.invoke(core.clj:105) at clojure.core$filter__5084$fn__5086.invoke(core.clj:1794) at clojure.lang.LazySeq.sval(LazySeq.java:42) at clojure.lang.LazySeq.seq(LazySeq.java:56) at clojure.lang.RT.seq(RT.java:440) ... If I do it right after again it always works. So it appears to be related to timing or something. The code in question is: (defn add-track [t] (common/ref-add tracks t)) (defn add-collection [coll] (doseq [track coll] (add-track track))) and (defn ref-add [ref value] (dosync (ref-set ref (conj @ref value)))) where coll is extracted from this function: (defn tracks-by-album [album] (sort sort-tracks (filter #(= (:album %) album) @tracks))) so it does appear to be the tracks-by-album function from the stack trace. I just don't see why it sometimes works and sometimes doesn't.

• Jar not found when executing class

  - by Simon

  Hi there, I'm working through the ANTLR book and there are many examples that should be easy to compile using the command line. Some information to get te problem: antlr-3.2.jar contains the ANTLR classes. I added the antlr-3.2.jar to the CLASSPATH environment variable (Windows 7) and when compiling the classes with javac everything works fine. This is what i execute to compile my program: javac Test.java ExprLexer.java ExprParser.java Test.java contains my main()-method whereas ExprLexer and ExprParser are generated by ANTLR. All three classes use classes contained in the antlr-3.2.jar. But so far so good. As I just said, compiling works fine. It's when I try to execute the Test.class that I get trouble. This is what I type: java -cp ./ Test When executing this, the interpreter tells me that he can't find the ANTLR-classes contained in the antlr-3.2.jar, altough I added an entry in the CLASSPATH variable. E:\simone\Programmierung\Language Processing Tools\ANTLR\Book Samples and Exercises\Exercise\1\output\Test.java Exception in thread "main" java.lang.NoClassDefFoundError: org/antlr/runtime/Cha rStream Caused by: java.lang.ClassNotFoundException: org.antlr.runtime.CharStream at java.net.URLClassLoader$1.run(URLClassLoader.java:202) at java.security.AccessController.doPrivileged(Native Method) at java.net.URLClassLoader.findClass(URLClassLoader.java:190) at java.lang.ClassLoader.loadClass(ClassLoader.java:307) at sun.misc.Launcher$AppClassLoader.loadClass(Launcher.java:301) at java.lang.ClassLoader.loadClass(ClassLoader.java:248) Could not find the main class: Test. Program will exit. I'm using Windows 7 and Java 1.6_20. Can someone tell what is going on? Why will the interpreter not look in the jar-Archive I specified in the CLASSPATH? I found some kind of workaroud. I copied the antlr-3.2.jar into the directory where the Test.class is located and then executed: java -cp ./;antlr-3.2.jar Test This worked out. But I don't want to type the jar-Archive everytime I execute my test programs. Is there a possibility to tell the interpreter that he should automatically look into the archive?

• Security error accessing Service outside of FlexBuilder

  - by MikeHoss

  I'm very new to Flex and I have what I think it a head-scratcher. I am building a little Flash app that will consume some web services over HTTP. When I am in Flexbuilder and run my app there, it works fine. When I goto to my FlexBuilder project on my OS and double-click on it, it works fine. When I zip up my bin-debug file, I get this error: Security error accessing url faultCode:Channel.Security.Error faultString: 'Security error accessing url' faultDetail:'Destination: DefaultHTTP' So I googled that and got information on about the crossdomain.xml file. Well, I can't put a crossdomain file in the service I am calling, but I can put one somewhere else. So I put the following lines in Flex app: Security.allowDomain("vx1391"); Security.loadPolicyFile("http://vx1391:8080/job/Remote%20FIT%20Runner/ws/trunk/flash-cross-domain.xml"); My cross-domain.xml file is wide-open: &lt;cross-domain-policy&gt; &lt;allow-access-from domain="*"/&gt; </cross-domain-policy> Which I know is bad in a prod enivironment, but right now I just need to get this working locally but outside of FlexBuilder. Anyone want to help out this Flex-noob?

• Binding property to Silverlight dependency property independent of DataContext

  - by Simon_Weaver

  I'm trying to make an Address control that has an IsReadOnly property, which will make every TextBox inside read only when set to true. <my:AddressControl Grid.Column="1" Margin="5" IsReadOnly="True"/> I've managed to do this just fine with a dependency property and it works. Here's a simple class with the dependency property declared : public partial class AddressControl : UserControl { public AddressControl() { InitializeComponent(); this.DataContext = this; } public static readonly DependencyProperty IsReadOnlyProperty = DependencyProperty.Register("IsReadOnly", typeof(bool), typeof(AddressControl), null); public bool IsReadOnly { get { return (bool)GetValue(IsReadOnlyProperty); } set { SetValue(IsReadOnlyProperty, value); } } } In the XAML for this codebehind file I have a Textbox for each address line: <TextBox IsReadOnly="{Binding IsReadOnly}" Text="{Binding City, Mode=TwoWay}"/> <TextBox IsReadOnly="{Binding IsReadOnly}" Text="{Binding State, Mode=TwoWay}"/> <TextBox IsReadOnly="{Binding IsReadOnly}" Text="{Binding Zip, Mode=TwoWay}"/> Like i said this works just fine. The problem is that the Address control itself is bound to its parent object (I have several addresses I am binding). <my:AddressControl DataContext="{Binding ShippingAddress, Mode=TwoWay}" IsReadOnly="True"> <my:AddressControl DataContext="{Binding BillingAddress, Mode=TwoWay}" IsReadOnly="True"> The problem is that as soon as I set DataContext to something other than 'this' then the binding for IsReadOnly breaks. Not surprising because its looking for IsReadOnly on the Address data entity and it doesn't exist or belong there. I've tried just about every combination of binding attributes to get IsReadOnly to bind to the AddressControl obejct but can't get it working. I've tried things like this, but I can't get IsReadOnly to bind independently to the AddressControl property instead of its DataContext. <TextBox IsReadOnly="{Binding RelativeSource={RelativeSource Self}, Path=IsReadOnlyProperty}" Text="{Binding City, Mode=TwoWay}" /> I think I'm pretty close. What am I doing wrong?

• Slow query with unexpected index scan

  - by zerkms

  Hello I have this query: SELECT * FROM sample INNER JOIN test ON sample.sample_number = test.sample_number INNER JOIN result ON test.test_number = result.test_number WHERE sampled_date BETWEEN '2010-03-17 09:00' AND '2010-03-17 12:00' the biggest table here is RESULT, contains 11.1M records. The left 2 tables about 1M. this query works slowly (more than 10 minutes) and returns about 800 records. executing plan shows clustered index scan (over it's PRIMARY KEY (result.result_number, which actually doesn't take part in query)) over all 11M records. RESULT.TEST_NUMBER is a clustered primary key. if I change 2010-03-17 09:00 to 2010-03-17 10:00 - i get about 40 records. it executes for 300ms. and plan shows index seek (over result.test_number index) if i replace * in SELECT clause to result.test_number (covered with index) - then all become fast in first case too. this points to hdd IO issues, but doesn't clarifies changing plan. so, any ideas? UPDATE: sampled_date is in table sample and covered by index. other fields from this query: test.sample_number is covered by index and result.test_number too. UPDATE 2: obviously than sql server in any reasons don't want to use index. i did a small experiment: i remove INNER JOIN with result, select all test.test_number and after that do SELECT * FROM RESULT WHERE TEST_NUMBER IN (...) this, of course, works fast. but i cannot get what is the difference and why query optimizer choose such inappropriate way to select data in 1st case.

• eclipse tomcat debug mode slow - pegs cpu

  Running Tomcat through eclipse works fine in non-debug mode, but not in debug mode. When I try to start the Tomcat server in debug mode, the console output looks fine for a while, but then starts slowing down and eventually just stops, pegging the cpu at 100%. I don't think it's relevant, but just in case - here's the console output right about when it starts slowing down and eventually stopping (by stopping I mean no more console output, but still 100% cpu). 2009-09-02 14:35:30,859 INFO NONE org.springframework.context.weaving.DefaultContextLoadTimeWeaver:72 - Found Spring's JVM agent for instrumentation 2009-09-02 14:35:49,562 INFO NONE org.springframework.beans.factory.support.DefaultListableBeanFactory:414 - Pre-instantiating singletons in org.springframework.beans.factory.support.DefaultListableBeanFactory@ed889d: defining beans [... 2009-09-02 14:37:31,031 INFO NONE org.springframework.orm.jpa.LocalContainerEntityManagerFactoryBean:221 - Building JPA container EntityManagerFactory for persistence unit ...

I had been running fine in debug-mode for several months prior to this issue. I didn't make any significant changes to our project that would cause this. Eventually, I upgraded to eclipse galileo which solved my problem. Now 2 days later, I'm having the same problem in galileo. Like I said it works fine in non-debug mode. Any help is much appreciated. I should add that other things work in debug mode - for instance junit tests, so it is something specific to tomcat.

• How can I copy a SQL record which has related records in other tables to the same database?

  - by DerekVS

  Hi. I created a function in C# which allows me to copy a record and its related children to a new record and new related children in the same database. (This is for an application that allows the use of previous work as a template for new work.) Anyway, it works great... Here's a description of how it accomplishes the copy: It populates a two-column memory-based look-up table with the current primary key of each record. Next, as it individually creates each new copy record, it updates the look-up table with the Identity PK of the new record [retrieved from SCOPE_IDENTITY()]. Now, when it copies over any related children, it can look up the new parent PK to set the FK on the new record. In testing, it only took a minute to copy a relational structure on a local instance of SQL Server 2005 Express Edition. Unfortunately it is proving to be horribly slow in production! My users are dealing with 60,000+ records per parent record over the LAN to our SQL Server! While my copy function still works, each of those records represents an individual SQL UPDATE command and it loads the SQL Server at about 17% CPU from its normal 2% idle. I just finished testing a 50,000 record copy and it took almost 20 minutes! Is there a way to duplicate this functionality in SQL queries or stored procecures to make the SQL server do all of the copy work instead of blasting it over the LAN from each client? (We're running Microsoft SQL Server 2005 Standard Edition.) Thanks! -Derek

• codeigniter & cjax framework, fatal error class 'CI_Controller' not found

  - by Martin

  I'm having this weird error with Codeigniter 2.1.3 and latest cjax for codeigniter. Weird thing is, when I download the latest codeigniter, and latest cjax framework for codeitniger and copy to my friends server, and call: domain.com/ajax.php?test/test2 to show the test ajax examples ... it works like a breeze, but when I do this on my server, I get server error (even tho, we both have same php version and such). Server then throws in error log file this error: PHP Fatal error: Class 'CI_Controller' not found in /hosting/www/domain.com/www/application/response/test.php on line 3 Now, I've read thru stackoverflow with people having this problem and solving by changing the construct and calling CI_Controller instead of Controller. But I already do that ... - I mean it's in the basic example that is suppose to work without touching the code, and it does, just not on my domain for some crappy reason. Ajax.php from cjax framework for codeingter should load controller from folder response, named test and call function test2, which looks like this (the actual file named test.php): class Test extends CI_Controller { function __construct() { parent::__construct(); } /** * * ajax.php?test/test/a/b/c * * @param unknown_type $a * @param unknown_type $b * @param unknown_type $c */ function test($a = null,$b = null, $c = null) { $this->load->view('test', array('data' => $a .' '.$b.' '.$c)); } /** * ajax.php?test/test2 * * Here we are testing out the javascript library. * * Note: the library it is not meant to be included in ajax controllers - but in front-controllers, * it is being used here for the sake of simplicity in testing. */ function test2() { $ajax = ajax(); $ajax->update('response','Cjax Works'); $ajax->append('#response','<br /><br />version: '.$ajax->version); $ajax->success('Cjax was successfully installed.', 5); //see application/views/test2.php $this->load->view('test2'); } I was hoping someone could bring some light into this problem - or maybe someone has already experienced it? Thanks for your time! Mart

• Spoofing UserAgent in Opera

  - by PoweRoy

  I'm trying to spoof Opera (under linux) to be an other browser, in this case iPad for some testing purposes. Now I know sites can check which browser is accessing the using for example in PHP $useragent = $_SERVER['HTTP_USER_AGENT']; and in javascript navigator.userAgent (or navigator.platform). In firefox you can use an addon to easily switch your useragent and other relevant information, but in Opera it seems it bit hard to do. First in opera.ini you can do: [User Agent] Spoof UserAgent ID=1 But this is limited to a predefined list of UserAgents. No room for custom ones. Also in opera.ini [ISP] Id=iPad This will add iPad to the User Agent of Opera. It's a start and works most of the time on the sites. In opera.ini you can set a 'User JavaScript file' to load a custom JavaScript file before loading a website: [User Prefs] User JavaScript File=/opera_dir/userjs/load.js In load.js you can do: navigator.userAgent = "Mozilla/5.0 (iPad; U; CPU OS 3_2 like Mac OS X; en-us) AppleWebKit/531.21.10 (KHTML, like Gecko) Version/4.0.4 Mobile/7B334b Safari/531.21.10" Because this file gets executed before loading the website I can modify the UserAgent, but this won't work when a site is checking the UserAgent via PHP, but it works for sites checking with Javascript) So here's my question: is there another way of spoofing a complete custom UserAgent?

• SharePoint custom web service consumption problems - HTTP 401: Unauthorized

  - by alekz

  I have a custom web service deployed into WSS 3. It has two web methods. The first one returns the version of the loaded assembly without any invocation of the SharePoint objects. The second returns some basic info about the library, something like: var spLibrary = [find library logic]; return spLibrary.Name+"@"+spLibrary.Url; In the client app I have something like the following: var service = new WebService1(); service.Url = [url]; service.Credentials = System.Net.CredentialCache.DefaultCredentials; service.Method1(); service.Method2(); When the client app runs on the machine where SharePoint is deployed, everything works just fine. When the client app runs on the remote machine (but under the same user) the first method still works, but the second one throws System.Net.WebException: HTTP 401: Unauthorized. I have tried to set credentials manualy (service.Credentials = new System.Net.NetworkCredential(login, password, domain);) but this doesnt help. I've tried to invoke the built in SharePoint web services using a similar scenario, and they work just fine: Sorry for the mistake... Some methods were not working fine without the appropriate privileges. var service = new GroupsService(); service.Url = [url]; service.Credentials = System.Net.CredentialCache.DefaultCredentials; service.SomeMethod();

• SVG animation along path with Raphael

  - by Toby Hede

  I have a rather interesting issue with SVG animation. I am animating along a circular path using Raphael obj = canvas.circle(x, y, size); path = canvas.circlePath(x, y, radius); path = canvas.path(path); //generate path from path value string obj.animateAlong(path, rate, false); The circlePath method is one I have created myself to generate the circle path in SVG path notation: Raphael.fn.circlePath = function(x , y, r) { var s = "M" + x + "," + (y-r) + "A"+r+","+r+",0,1,1,"+(x-0.1)+","+(y-r)+" z"; return s; } So far, so good. This all works. I have my object (obj) animating along the circular path. BUT: The animation only works if I create the object at the same X, Y coords as the path itself. If I start the animation from any other coordinates (say, half-way along the path) the object animates in a circle of the correct radius, however it starts the animation from the object X,Y coordinates, rather than along the path as it is displayed visually. Ideally I would like to be able to stop/start the animation - the same problem occurs on restart. When I stop then restart the animation, it animates in a circle starting from the stopped X,Y.

• jquery ajax using 'addresses' to update url for bookmarking

  - by Jay

  $("document").ready(function(){ contM = $('#main-content'); contS = $('#second-content'); $(contM).hide(); $(contS).hide(); function loadURL(url) { console.log("loadURL: " + url); $.post(url,{post_loader: 1},{post_loader: 1}, function(data){ $(contM).html($(data)); $(contM).show(); }); } // Event handlers $.address.init(function(event) { console.log("init: " + $('[rel=address:' + event.value + ']').attr('href')); }).change(function(event) { $.post($('[rel=address:' + event.value + ']').attr('href'), {post_loader: 1}, function(data){ $(contM).html($(data)); $(contM).show(); }); console.log("change"); }) $('.update-main a').click(function(){ loadURL($(this).attr('href')); }); }); I'm using this code to make calls to a server to update the main content of a web page. Everything works fine in Google Chrome, but fails to execute properly in Firefox. The strange thing is that when I have the console open to monitor server communication, the application works fine, only when it is closed do problems occur : the script starts to communicate with the server, but before it receives the data the browser jumps to the source url. any ideas?
