  • Set ContentTemplate in CodeBehind: XamlParseException 2260 Error

    - by user362215
    Hi, I'd like to change the ContentTemplate of a ContentPresenter in the CodeBehind file. But if I run the Silverlight 4 application a XamlParseException with the error code 2260 occures. foreach (ContentPresenter item in Headers) { item.ContentTemplate = Parent.UnselectedHeaderTemplate; } if ((index >= 0) && (index < Headers.Count)) { ContentPresenter item0 = (ContentPresenter)Headers[index]; item0.ContentTemplate = Parent.SelectedHeaderTemplate; } If I do only the foreach code without the code in the "if", it works. And if I only do the code in the "if" without the foreach it works too. But togheter (the "if"-code and the foreach-code) it doesn't work. I have no idea why it doesn't work. The two templates look like this: <Setter Property="UnselectedHeaderTemplate"> <Setter.Value> <DataTemplate> <ContentControl Content="{Binding RelativeSource={RelativeSource TemplatedParent}, Path=Content}" Margin="10,-10" FontSize="72" Foreground="#FF999999" CacheMode="BitmapCache"/> </DataTemplate> </Setter.Value> </Setter> <!-- SelectedHeader template --> <Setter Property="SelectedHeaderTemplate"> <Setter.Value> <DataTemplate> <ContentControl Content="{Binding RelativeSource={RelativeSource TemplatedParent}, Path=Content}" Margin="10,-10" FontSize="72" Foreground="{TemplateBinding Foreground}" CacheMode="BitmapCache"/> </DataTemplate> </Setter.Value> </Setter> If you have an idea what problem is please tell me.

  • How best to associate code with events in jQuery?

    - by Ned Batchelder
    Suppose I have a <select> element on my HTML page, and I want to run some Javascript when the selection is changed. I'm using jQuery. I have two ways to associate the code with the element. Method 1: jQuery .change() <select id='the_select'> <option value='opt1'>One</option> <option value='opt2'>Two</option> </select> <script> $('#the_select').change(function() { alert('Changed!'); }); </script> Method 2: onChange attribute <select id='the_select' onchange='selectChanged();'> <option value='opt1'>One</option> <option value='opt2'>Two</option> </select> <script> function selectChanged() { alert('Changed!'); } </script> I understand the different modularity here: for example, method 1 keeps code references out of the HTML, but method 2 doesn't need to mention HTML ids in the code. What I don't understand is: are there operational differences between these two that would make me prefer one over the other? For example, are there edge-case browsers where one of these works and the other doesn't? Is the integration with jQuery better for either? Does the late-binding of the code to the event make a difference in the behavior of the page? Which do you pick and why?

  • How to store child objects on GAE using JDO from Scala

    - by Gero
    Hi, I'm have a parent-child relation between 2 classes, but the child objects are never stored. I do get an warning: "org.datanucleus.store.appengine.MetaDataValidator checkForIllegalChildField: Unable to validate relation net.vermaas.kivanotify.model.UserCriteria.internalCriteria" but it is unclear to me why this occurs. Already tried several alternatives without luck. The parent class is "UserCriteria" which has a List of "Criteria" as children. The classes are defined as follows (Scala): class UserCriteria(tu: String, crit: Map[String, String]) extends LogHelper { @PrimaryKey @Persistent{val valueStrategy = IdGeneratorStrategy.IDENTITY} var id = KeyFactory.createKey("UserCriteria", System.nanoTime) @Persistent var twitterUser = tu @Persistent var internalCriteria: java.util.List[Criteria] = flatten(crit) def flatten(crits: Map[String, String]) : java.util.List[Criteria] = { val list = new java.util.ArrayList[Criteria] for (key <- crits.keySet) { list.add(new Criteria(this, key, crits(key))) } list } def criteria: Map[String, String] = { val crits = mutable.Map.empty[String, String] for (i <- 0 to internalCriteria.size-1) { crits(internalCriteria.get(i).name) = internalCriteria.get(i).value } Map.empty ++ crits } // Stripped the equals, canEquals, hashCode, toString code to keep the code snippet short... } @PersistenceCapable @EmbeddedOnly class Criteria(uc: UserCriteria, nm: String, vl: String) { @Persistent var userCriteria = uc @Persistent var name = nm @Persistent var value = vl override def toString = { "Criteria name: " + name + " value: " + value } } Any ideas why the childs are not stored? Or why I get the error message? Thanks, Gero

  • postgresql help with php loop....

    - by KnockKnockWhosThere
    I keep getting an "Notice: Undefined index: did" error with this query, and I'm not understanding why... I'm much more used to mysql, so, maybe the syntax is wrong? This is the php query code: function get_demos() { global $session; $demo = array(); $result = pg_query("SELECT DISTINCT(did,vid,iid,value) FROM dv"); if(pg_num_rows($result) > 0) { while($r = pg_fetch_array($result)) { switch($r['did']) { case 1: $demo['a'][$r['vid']] = $r['value']; break; case 2: $demo['b'][$r['vid']] = $r['value']; break; case 3: $demo['c'][$r['vid']] = $r['value']; break; } } } else { $session->session_setMessage(2); } return $demo; } When I run that query at the pg prompt, I get results: "(1,1,1,"A")" "(1,2,2,"B")" "(1,3,3,"C")" "(1,4,4,"D")" "(1,5,5,"E")" "(1,6,6,"F")" "(1,7,7,"G")" "(1,8,8,"H")" "(1,9,9,"I")" "(1,10,A,"J")" "(1,11,B,"K")" "(1,12,C,"L")" "(1,13,D,"M")" "(2,14,1,"A")" "(2,15,2,"B")" "(2,16,0,"C")" "(3,17,1,"A")" "(3,18,2,"B")" "(3,19,3,"C")" "(3,20,4,"D")" "(3,21,5,"E")" "(3,22,6,"F")" "(3,23,7,"G")"

  • How can I make an event created through Google Calendar's API send an invitation email?

    - by Cebjyre
    I'm trying to create an event through the API and it is mostly working, with the exception that while the new events are being created in the invitees calendars, no emails are being sent. Creating the event from the web interface is pushing the event through, as well as sending the email (except one account that doesn't get any notifications at all, but that's not relevant to my current problem). The event I am trying to push in is: <entry xmlns='http://www.w3.org/2005/Atom' xmlns:gd='http://schemas.google.com/g/2005'> <category scheme='http://schemas.google.com/g/2005#kind' term='http://schemas.google.com/g/2005#event'></category> <title type='text'>test event</title> <content type='text'>content.</content> <gd:transparency value='http://schemas.google.com/g/2005#event.opaque'> </gd:transparency> <gd:eventStatus value='http://schemas.google.com/g/2005#event.confirmed'> </gd:eventStatus> <gd:where valueString='somewhere'></gd:where> <gd:who email="[redacted]" rel='http://schemas.google.com/g/2005#event.attendee' valueString='Me'><gd:attendeeStatus value='http://schemas.google.com/g/2005#event.invited'/></gd:who> <gd:who email="[redacted again]" rel='http://schemas.google.com/g/2005#event.organizer' valueString='Also Me'><gd:attendeeStatus value='http://schemas.google.com/g/2005#event.accepted'/></gd:who> <gd:when startTime='2010-05-18T15:30:00.000+10:00' endTime='2010-05-18T16:00:00.000+10:00'></gd:when> </entry> And when I request event lists I can't see any large difference between events created through the API and through the web interface.

  • Why is there a time lag when trying to change the text on a button in IE using JQuery?

    - by Deane
    I have some Ajax that runs on a button click. Sometimes it takes a few seconds to return, so I wanted a visual clue to the user that the browser was doing something. So, I have this: $('#SubmitButton').attr("value", "Working..."); $('#SubmitButton').attr("disabled", true); //Synchronous Ajax call goes here $('#SubmitButton').attr("value", "Submit"); $('#SubmitButton').attr("disabled", false); As you can see, it changes the text on the button, and disables it. When the Ajax call comes back (it's synchronous, remember), the button changes back. In Firefox, this works great. In IE, it's...odd. It doesn't run the code in order. It doesn't change the text of the button and launches right into the Ajax call. The browser blocks with the Submit active and saying "Submit." Right after the Ajax comes back, the button quickly flashes "Working..." then back to Submit." So, for some reason, IE isn't changing the text of the button until after the Ajax call, even though the code for it is before the Ajax call. It's acting like this: //Synchronous Ajax call goes here $('#SubmitButton').attr("value", "Working..."); $('#SubmitButton').attr("disabled", true); $('#SubmitButton').attr("value", "Submit"); $('#SubmitButton').attr("disabled", false); Again, this works perfectly in Firefox. But in IE, there's some kind of...lag?

  • What's wrong with my object tag to embed a Java Applet?

    - by predhme
    Here is my object tag. <object classid="java:my.full.class.Name.class" height="360" width="320"> <param name="type" value="application/x-java-applet"> <param name="archive" value="applets.jar"> <param name="file" value="/report_files/1-1272041330710YAIwK"> <param name="codebase" value="/applets"> </object> When I run this in firefox it just shows up with an Error, click for details. The java console shows absolutely nothing. And at the bottom of fire fox is says "Applet my.full.class.Name notloaded". The Name.class file is in the applets.jar file. I can type the URL /applets/applets.jar and access the jar file. So whats wrong? EDIT: I can access the param file as well, although I don't believe that is the issue. EDIT: I updated the tag because I noticed in my HTML logs it wasn't looking in the right place. Still nothing though

  • javascript, php, cookies

    - by kennedy
    When i declare mac = 123, my internet explorer and firefox will keep refresh non-stop. And if i declare mac = getMacAddress it returns a value 1... I'm able to do a document.write(getMacAddress()) and it would able to display the mac address nicely. 1) Why my explorer will keep refreshing non-stop when i code it manually with "123" 2) why is the document.write able to display out, and when i store it to the cookie, somehow it didnt mange to capture into the cookie and it return a value of "1". Anyone help? create_users.php <script language="JavaScript"> function getMacAddress(){ document.macaddressapplet.setSep( "-" ); return (document.macaddressapplet.getMacAddress()); } function setCookie(c_name,value) { document.cookie = c_name + "=" +escape(value); } //error checking //var mac = getMacAddress(); var mac = "123"; setCookie('cookie_name',mac); window.location = "checkAvailability.php"; </script> checkAvailability.php $javascript_cookie_value = isset($_COOKIE["cookie_name"]) ? $_COOKIE["cookie_name"] : 1; mysql_query("INSERT INTO test (mac) VALUES ('$javascript_cookie_value')");

  • How do I perform this MutliArray setup in Java?

    - by Andy Barlow
    I come from a PHP background and I'm just getting my teeth into some Java. I was wondering how I could implement the following in Java as simply as possible, just echoing the results to a terminal via the usual "System.out.print()" method. <?php $Results[0]['title'] = "No Country for Old Men"; $Results[0]['run_time'] = "122 mins"; $Results[0]['cert'] = "15"; $Results[1]['title'] = "Old School"; $Results[1]['run_time'] = "88 mins"; $Results[1]['cert'] = "18"; // Will basically show the above in order. foreach($Results as value) { echo $Results[$value]['title']; echo $Results[$value]['run_time']; echo $Results[$value]['cert']; } // Lets add some more as I need to do this in Java too $Results[2]['title'] = "Saving Private Ryan"; $Results[2]['run_time'] = "153 mins"; $Results[2]['cert'] = "15"; // Lets remove the first one as an example of another need $Results[0] = null; ?> I hear there are "list iterators" or something that are really good for rolling through data like this. Perhaps it could be implemented with that? A fully working .java file would be most handy in this instance, including how to add and remove items from the array like the above. P.S. I do plan on using this for an Android App in the distant future, so, hopefully it should all work on Android fine too, although, I imagine this sort of thing works on anything Java related :).

  • Common Lisp condition system for transfer of control

    - by Ken
    I'll admit right up front that the following is a pretty terrible description of what I want to do. Apologies in advance. Please ask questions to help me explain. :-) I've written ETLs in other languages that consist of individual operations that look something like: // in class CountOperation IEnumerable<Row> Execute(IEnumerable<Row> rows) { var count = 0; foreach (var row in rows) { row["record number"] = count++; yield return row; } } Then you string a number of these operations together, and call The Dispatcher, which is responsible for calling Operations and pushing data between them. I'm trying to do something similar in Common Lisp, and I want to use the same basic structure, i.e., each operation is defined like a normal function that inputs a list and outputs a list, but lazily. I can define-condition a condition (have-value) to use for yield-like behavior, and I can run it in a single loop, and it works great. I'm defining the operations the same way, looping through the inputs: (defun count-records (rows) (loop for count from 0 for row in rows do (signal 'have-value :value `(:count ,count @,row)))) The trouble is if I want to string together several operations, and run them. My first attempt at writing a dispatcher for these looks something like: (let ((next-op ...)) ;; pick an op from the set of all ops (loop (handler-bind ((have-value (...))) ;; records output from operation (setq next-op ...) ;; pick a new next-op (call next-op))) But restarts have only dynamic extent: each operation will have the same restart names. The restart isn't a Lisp object I can store, to store the state of a function: it's something you call by name (symbol) inside the handler block, not a continuation you can store for later use. Is it possible to do something like I want here? Or am I better off just making each operation function explicitly look at its input queue, and explicitly place values on the output queue?

  • Php/Regex get the contents between a set of double quotes

    - by Davy Arnold
    Update to my question: My goal overall is to split the string into 4 parts that I can access later. value = " result of the html inside the first and last " " Here is an example of what i'm trying to do: // My string (this is dynamic and will change, this is just an example) $string = 'value="<p>Some text</p> <a href="#">linky</a>"'; // Run the match and spit out the results preg_match_all('/([^"]*)(?:\s*=\s*(\042|\047))([^"]*)/is', $string , $results); // Here is the array I want to end up with Array ( [0] => Array ( [0] => value="<p>Some text</p><a href="#">linky</a>" ) [1] => Array ( [0] => value ) [2] => Array ( [0] => " ) [3] => Array ( [0] => <p>Some text</p><a href="#">linky</a> ) ) Basically the double quotes on the link are causing me some trouble so my first though was to do [^"]$ or something to have it just run until the last double quote, but that isn't getting me anywhere. Another idea I had was maybe process the string in PHP to strip out any inner quotes, but i'm not sure ho to go about this either. Hopefully I'm being clear, it is pretty late and i've been at this far too long!

  • Alloy MVC Framework Titanium Network (Model)

    - by flyingDuck
    I'm trying to authenticate using the Model in Alloy. I have been trying to figure this problem out since yesterday. If anybody could help me, I'd really appreciate it. So, I have a view login.xml, then a controller login.js. The login.js contains the following function: var user = Alloy.Models.user; //my user.js model function login(e) { if($.username.value !== '' && $.password.value !== ''){ if(user.login($.username.value, $.password.value)){ Alloy.createController('home').getView().open(); $.login.close(); } }else{ alert('Username and/or Password required!'); } } Then in my user.js model, it's like this: extendModel : function(Model) { _.extend(Model.prototype, { login: function(username, password) { var first_name, last_name, email; var _this = this; var url = 'http://myurl.com/test.php'; var auth = Ti.Network.createHTTPClient({ onerror: function(e){ alert(e.error); }, onload: function(){ var json = this.responseText; var response = JSON.parse(json); if(response.logged == true){ first_name = response.f_name; last_name = response.l_name; email = response.email; _this.set({ loggedIn: 1, username: email, realname: first_name + ' ' + last_name, email: email, }); _this.save(); }else{ alert(response.message); } }, }); auth.open('POST', url); var params = { usernames: username, passwords: password, }; auth.send(params); alert(_this.get('email')); //alert email }, }); When I click on login in login.xml it calls the function login in index.js. So, now my problem is that, when I click the button for the first time, I get an empty alert from alert(_this.get('email')), but then when I click the button the second time, everything works fine, it alerts the email. I have no idea what's going on. Thank you for the help.

  • .Net lambda expression-- where did this parameter come from?

    - by larryq
    I'm a lambda newbie, so if I'm missing vital information in my description please tell me. I'll keep the example as simple as possible. I'm going over someone else's code and they have one class inheriting from another. Here's the derived class first, along with the lambda expression I'm having trouble understanding: class SampleViewModel : ViewModelBase { private ICustomerStorage storage = ModelFactory<ICustomerStorage>.Create(); public ICustomer CurrentCustomer { get { return (ICustomer)GetValue(CurrentCustomerProperty); } set { SetValue(CurrentCustomerProperty, value); } } private int quantitySaved; public int QuantitySaved { get { return quantitySaved; } set { if (quantitySaved != value) { quantitySaved = value; NotifyPropertyChanged(p => QuantitySaved); //where does 'p' come from? } } } public static readonly DependencyProperty CurrentCustomerProperty; static SampleViewModel() { CurrentCustomerProperty = DependencyProperty.Register("CurrentCustomer", typeof(ICustomer), typeof(SampleViewModel), new UIPropertyMetadata(ModelFactory<ICustomer>.Create())); } //more method definitions follow.. Note the call to NotifyPropertyChanged(p => QuantitySaved) bit above. I don't understand where the "p" is coming from. Here's the base class: public abstract class ViewModelBase : DependencyObject, INotifyPropertyChanged, IXtremeMvvmViewModel { public event PropertyChangedEventHandler PropertyChanged; protected virtual void NotifyPropertyChanged<T>(Expression<Func<ViewModelBase, T>> property) { MvvmHelper.NotifyPropertyChanged(property, PropertyChanged); } } There's a lot in there that's not germane to the question I'm sure, but I wanted to err on the side of inclusiveness. The problem is, I don't understand where the 'p' parameter is coming from, and how the compiler knows to (evidently?) fill in a type value of ViewModelBase from thin air? For fun I changed the code from 'p' to 'this', since SampleViewModel inherits from ViewModelBase, but I was met with a series of compiler errors, the first one of which statedInvalid expression term '=>' This confused me a bit since I thought that would work. Can anyone explain what's happening here?

  • LinQ XML mapping to a generic type

    - by Manuel Navarro
    I´m trying to use an external XML file to map the output from a stored procedure into an instance of a class. The problem is that my class is of a generic type: public class MyValue<T> { public T Value { get; set; } } Searching through a lot of blogs an articles I've managed to get this: <?xml version="1.0" encoding="utf-8" ?> <Database Name="" xmlns="http://schemas.microsoft.com/linqtosql/mapping/2007"> <Table Name="MyValue" Member="MyNamespace.MyValue`1" > <Type Name="MyNamespace.MyValue`1"> <Column Name="Category" Member="Value" DbType="VarChar(100)" /> </Type> </Table> <Function Method="GetResourceCategories" Name="myprefix_GetResourceCategories" > <ElementType Name="MyNamespace.MyValue`1"/> </Function> </Database> The MyNamespace.MyValue`1 trick works fine, and the class is recognized. I expect four rows from the stored procedure, and I'm getting four MyValue<string> instances, but the big problem is that the property Value for the all four instances is null. The property is not getting mapped and I don't really get why. Maybe worth noting that the property Value is generic, and that when the mapping is done using attributes it works perfect. Anyone have a clue? BTW the method GetResourceCategories: public ISingleResult<MyValue<string>> GetResourceCategories() { IExecuteResult result = this.ExecuteMethodCall( this, (MethodInfo)MethodInfo.GetCurrentMethod()); return (ISingleResult<MyValue<string>>)result.ReturnValue; }

  • Implementation of delegates in C#

    - by Ram
    Hi, I am trying to learn on how to use delegates efficiently in C# and I was just wondering if anyone can guide me through... The following is a sample implementation using delegates... All I am doing is just passing a value through a delegate from one class to another... Please tell me if this is the right way to implement... And also your suggestions... Also, please note that I have de-registered the delegate in : void FrmSample_FormClosing(object sender, FormClosingEventArgs e) { sampleObj.AssignValue -= new Sample.AssignValueDelegate(AssignValue); } Is this de-registration necessary? The following is the code that I have written.. public partial class FrmSample : Form { Sample sampleObj; public FrmSample() { InitializeComponent(); this.Load += new EventHandler(FrmSample_Load); this.FormClosing += new FormClosingEventHandler(FrmSample_FormClosing); sampleObj = new Sample(); sampleObj.AssignValue = new Sample.AssignValueDelegate(AssignValue); } void FrmSample_FormClosing(object sender, FormClosingEventArgs e) { sampleObj.AssignValue -= new Sample.AssignValueDelegate(AssignValue); } void FrmSample_Load(object sender, EventArgs e) { sampleObj.LoadValue(); } void AssignValue(string value) { MessageBox.Show(value); } } class Sample { public delegate void AssignValueDelegate(string value); public AssignValueDelegate AssignValue; internal void LoadValue() { if (AssignValue != null) { AssignValue("This is a test message"); } } } Pls provide your feedback on whether this is right... Thanks, Ram

  • How to show a form field ONLY if another is selected in JavaScript or jQuery?

    - by Sam
    I have a form, like so: <form action="" method="post"> <select name="pageType"> <option value="main">Main Page</option> <option value="sub">Sub Page</option> <option value="sub-sub">Sub-Sub Page</option> </select> <br /> <label>Choose Sub Sub Name:</label> <input type="text" name="sub-sub-name" /> <br /> <input type="submit" name="submit" value="GO!" /> </form> What I would like to achive is for this text field (and it's label): <label>Choose Sub Sub Name:</label> <input type="text" name="sub-sub-name" /> to only appear if the 3rd option (sub sub page) is selected from the drop down and not show up otherwise. How can this be done with either javascript or the jquery framework? EDIT by the way, it would be nice if this can be achieved without the page needing to refresh and losing previously submitted form data. I know form data can still be kept using variables that store the values even on page refresh, but I was hoping for that effect that I see on a lot of sites where the additional text area (or other form element) just appears without page refresh.

  • ResourceFilterFactory and non-Path annotated Resources

    - by tousdan
    (I'm using Jersey 1.7) I am attempting to add a ResourceFilterFactory in my project to select which filters are used per method using annotations. The ResourceFilterFactory seems to be able to filters on Resources which are annotated with the Path annotation but it would seem that it does not attempt to generate filters for the methods of the SubResourceLocator of the resources that are called. @Path("a") public class A { //sub resource locator? @Path("b") public B getB() { return new B(); } @GET public void doGet() {} } public class B { @GET public void doOtherGet() { } @Path("c") public void doInner() { } } When ran, the Filter factory will only be called for the following: AbstractResourceMethod(A#doGet) AbstractSubResourceLocator(A#getB) When I expected it to be called for every method of the sub resource. I'm currently using the following options in my web.xml; <init-param> <param-name>com.sun.jersey.spi.container.ResourceFilters</param-name> <param-value>com.my.MyResourceFilterFactory</param-value> </init-param> <init-param> <param-name>com.sun.jersey.config.property.packages</param-name> <param-value>com.my.resources</param-value> </init-param> Is my understanding of the filter factory flawed?

  • JSP: Refresh ComboBox options

    - by framara
    Hi, There's a class 'Car' with brand and model as properties. I have a list of items of this class List<Car> myCars. I need to represent in a JSP website 2 ComboBox, one for brand and another for model, that when you select the brand, in the model list only appear the ones from that brand. I don't know how to do this in a dynamic way. Any suggestion where to start? Thanks Update Ok, what I do now is send in the request a list with all the brand names, and a list of the items. The JSP code is like: <select name="manufacturer" id="id_manufacturer" onchange="return getManufacturer();"> <option value=""></option> <c:forEach items="${manufacturers}" var="man"> <option value="${man}" >${man}</option> </c:forEach> </select> <select name="model" id="id_model"> <c:forEach items="${mycars}" var="car"> <c:if test="${car.manufacturer eq man_selected}"> <option value="${car.id}">${car.model}</option> </c:if> </c:forEach> </select> <script> function getManufacturer() { man_selected = document.getElementById('id_manufacturer').value; } </script> How do I do to refresh the 'model' select options according to the selected 'man_selected' ?

  • Inserting javascript with jQuery .html

    - by Andrew Appleby
    I'm experiencing an issue with a website I'm working on, where I originally believed I could simply replace $("main").html('THIS') which was originally code for a flash object, with a new and improved HTML5/Javascript version. The original code: $("#main").html('<div style="height: 100%; width: 100%; overflow: hidden;"><object width="100%" height="100%" codebase="http://fpdownload.macromedia.com/pub/shockwave/cabs/flash/swflash.cab#version=8,0,0,0" classid="clsid:d27cdb6e-ae6d-11cf-96b8-444553540000">\ <param value="images/uploads/'+image_id+'.swf" name="movie">\ <param value="true" name="allowFullScreen">\ <param value="#737373" name="bgcolor">\ <param value="" name="FlashVars">\ <embed width="100%" height="100%" flashvars="" bgcolor="#737373" allowfullscreen="true" src="images/uploads/'+image_id+'.swf" type="application/x-shockwave-flash" pluginspage="http://www.macromedia.com/go/getflashplayer">\ </object></div>\ '); }); And my (failed) attempt at inserting my new code: $("#main").html('<script type="text/javascript">pano=new pano2vrPlayer("container");skin=new pano2vrSkin(pano);pano.readConfigUrl("xml/tablet_'+image_id+'.xml");hideUrlBar();</script>'); It doesn't even work when I just put , so I know it's gotta be the javascript itself. I've looked at the solutions out there, but I can't make sense in how to properly implement them here in the most efficient way. Your help is much appreciated, thanks!

    - by Yan Cheng CHEOK
    My following C code works quite well, till my Python code trying to pass an array of char pointer to it. The output I obtain is The file_name is python-file Another 3 string is not being printed out. Anything I had missed out? C Code #include <iostream> #include "c_interface.h" int foo(const char* file_name, const char** names) { std::cout << "The file_name is " << file_name << std::endl; while (*names) { std::cout << "The name is " << *names << std::endl; names++; } return 0; } /* int main() { const char *c[] = {"123gh", "456443432", "789", 0}; foo("hello", c); getchar(); } */ Python Code #!c:/Python27/python.exe -u from ctypes import * name0 = "NAME0" name1 = "NAME1" name2 = "NAME2" names = ((c_char_p * 1024) * 4)() names[0].value = name0 names[1].value = name1 names[2].value = name2 names[3].value = 0 libc = CDLL("foo.dll") libc.foo("python-file", names)

  • WPF - How do I use the UserControl with a dependency property and view model?

    - by user320849
    Hello, My goal is to have a user select a year and a month. Translate the selection into a date and have the user control send the date back to my view model. That part works for me....However, I cannot get the ViewModel's initial date to set those drop downs. public static readonly DependencyProperty Date = DependencyProperty.Register("ReturnDate", typeof(DateTime), typeof(DatePicker), new FrameworkPropertyMetadata{BindsTwoWayByDefault = true,}); public DateTime ReturnDate { get { return Convert.ToDateTime(GetValue(Date)); } set { SetDropDowns(value); SetValue(Date, value); } } The SetDropDowns(value) just sets the selected items on the combo boxes, however, the program never makes it to that method. On the view I am using: <cc1:DatePicker ReturnDate="{Binding Path=StartDate, Mode=TwoWay}" IsStart="True" /> If this has been answered, then my bad. I looked around and didn't see anything that worked for me. Thus, when the program loads how do I get the value from the view model to a method in order to set the combo boxes? Thanks, -Scott

  • I have a WPF/Silverlight ListView whose height is unpredictable and too high. How do I control it be

    - by Rob Perkins
    I have a ListView element with a DataTemplate for each ListViewItem defined as follows. When run, the ListView's height is not collapsed onto the items in the view, which is undesirable behavior: <DataTemplate x:Key="LicenseItemTemplate"> <Grid> <Grid.RowDefinitions> <RowDefinition Height="Auto" /> <RowDefinition Height="Auto" /> </Grid.RowDefinitions> <TextBlock Grid.Row="0" Text="{Binding company}"></TextBlock> <Grid Grid.Row="1" Style="{StaticResource HiddenWhenNotSelectedStyle}"> <Grid.RowDefinitions> <RowDefinition /> </Grid.RowDefinitions> <Button Grid.Row="0">ClickIt</Button> </Grid> </Grid> </DataTemplate> The second row of the outer grid has a style applied which looks like this. The purpose of the style is to : <Style TargetType="{x:Type Grid}" x:Key="HiddenWhenNotSelectedStyle" > <Style.Triggers> <DataTrigger Binding="{Binding Path=IsSelected, RelativeSource={ RelativeSource Mode=FindAncestor, AncestorType={x:Type ListViewItem} } }" Value="False"> <Setter Property="Grid.Visibility" Value="Collapsed" /> </DataTrigger> <DataTrigger Binding="{Binding Path=IsSelected, RelativeSource={ RelativeSource Mode=FindAncestor, AncestorType={x:Type ListViewItem} } }" Value="True"> <Setter Property="Grid.Visibility" Value="Visible" /> </DataTrigger> </Style.Triggers> </Style> The ListView renders like this: The desired appearance is this, when none of the elements are selected: ...with, of course, the ListView's height adjusting to accommodate the additional content when the second grid is made visible by selection. What can I do to get the desired behavior?

  • Web service performing asynchronous call

    - by kornelijepetak
    I have a webservice method FetchNumber() that fetches a number from a database and then returns it to the caller. But just before it returns the number to the caller, it needs to send this number to another service so instantiates and runs the BackgroundWorker whose job is to send this number to another service. public class FetchingNumberService : System.Web.Services.WebService { [WebMethod] public int FetchNumber() { int value = Database.GetNumber(); AsyncUpdateNumber async = new AsyncUpdateNumber(value); return value; } } public class AsyncUpdateNumber { public AsyncUpdateNumber(int number) { sendingNumber = number; worker = new BackgroundWorker(); worker.DoWork += asynchronousCall; worker.RunWorkerAsync(); } private void asynchronousCall(object sender, DoWorkEventArgs e) { // Sending a number to a service (which is Synchronous) here } private int sendingNumber; private BackgroundWorker worker; } I don't want to block the web service (FetchNumber()) while sending this number to another service, because it can take a long time and the caller does not care about sending the number to another service. Caller expects this to return as soon as possible. FetchNumber() makes the background worker and runs it, then finishes (while worker is running in the background thread). I don't need any progress report or return value from the background worker. It's more of a fire-and-forget concept. My question is this. Since the web service object is instantiated per method call, what happens when the called method (FetchNumber() in this case) is finished, while the background worker it instatiated and ran is still running? What happens to the background thread? When does GC collect the service object? Does this prevent the background thread from executing correctly to the end? Are there any other side-effects on the background thread? Thanks for any input.
