  • Wpf SelectedItem wont work for a Combobox in a ListView

    - by ChristianRo
    Hi there, I´ve got a problem with a Combobox in a ListView. I´ve got a class called "Substrate". This class contains an object of a class called "SubstrateType". I want to show the objects of the class "Substrate" in a Listview. Each property of the "Substrate" is presented in the columns of the Listview. For the different "SubstrateType" I want to use a combobox. In the XAML I tried it like this: <ComboBox Name="CBType" ItemsSource="{Binding ElementName=SettingsSubstrate, Path=TypeList}" SelectedItem="{Binding Path=Substrate.SubstrateType}" DisplayMemberPath="Description"/> In the code-behind I got two ObservableCollections. One for all Substrates and one for all possible SubstrateTypes. The combobox displays all SubstrateTypes if you click on it. But the combobox has no selecteditem if you dont select one. http://i44.tinypic.com/2eakxav.png Thanks in advance.

  • Add a custom format in Rails (that will work with respond_to)

    - by Horace Loeb
    I have map.resources :posts and I want to be able to serve post bodies in markdown format. So I set up my respond_to block: respond_to do |format| format.markdown { render :text => @post.body.to_s } end But when I try to access /posts/1234.markdown, I get this error: NameError (uninitialized constant Mime::MARKDOWN): app/controllers/posts_controller.rb:96:in `show' app/controllers/posts_controller.rb:79:in `show' How do I add markdown as an acceptable format? Where can I see the list of acceptable formats?

  • Ipad Magazines App How do they work?

    - by Terente Ionut Alexandru
    How are built the magazines apps? For example Popular Science, Auto Trends and PARIS MATCH I want to build an app like this. But how do these app render the content? How the app knows where is an video, an photo, scroll views and so on? Is there any library to use, and do this easy way or do I need my own engine that renders the content? Is just an webView that loads html5, css and java script or is much more than that?

  • @font-face fonts only work on their own domain

    - by Ben
    I am trying to create a type of font repository for use on my websites, so that I can call to any font in the repository in my css without any other set-up. To do this I created a subdomain on which I placed folders for each font in the repository that contained the various file types for each font. I also placed a css file called font-face.css on the root of the subdomain and filled it with @font-face declarations for each of the fonts, the fonts a linked with an absolute link so that they can be used from anywhere. My issue is that it seems that I can only use the fonts on that subdomain where they are located, on my other sites the font does not show. Using firebug I determined that the font-face.css file was successfully being linked to and loaded. So why does the font not correctly load? Is there protection on the font files or something? I am using all fonts that I should be allowed to do this with, so I don't see why this is occurring. Maybe it is an apache issue, but I can download the font just fine when I link to it. Oh, and just to clarify, I am not violating any copyrights by setting this up, all the fonts I am using are licensed to allow this sort of thing. I would however like to set up a way that only I can have access to this repository of fonts but that's another project.

  • Can't get UpdateAttributeRequest to work

    - by dsabater
    I am trying to use the Metadata Web Service of Dynamics CRM to update the order of some picklist options using the UpdateAttributeRequest message. Though I get to change the attribute's DisplayName using the MergeLabels = false option, the picklist option values themselves seem immutable.

  • sIFR - getting a:hover to work in navigation list

    - by HudRom
    Hi, I am currently struggling with sIFR and a:hover. My problem site is hosted at http://irene.huditsch.info I have the following HTML code: <body id="irene-huditsch-info"> <div id="header"> <h1>Irene Huditsch</h1> <div id="top-nav"> <ul> <li id="impressum"> <a href="impressum.html" rel="index">Impressum</a> </li> <li id="kontakt"> <a href="kontakt.html">Kontakt</a> </li> </ul> </div> ... My sIFR-config.js looks like: sIFR.replace(braganza, { selector: 'div#top-nav a', css: '.sIFR-root { background-color: transparent; color: #FFFFFF; line-height: 13px; font-size: 11px; text-decoration: underline; cursor: pointer; } .sIFR-root:hover { color: #592b02; }', wmode: 'transparent' }); But the hover doesn't take effect. I tried different solution with no success either. When I write sIFR.replace(braganza, { selector: 'div#top-nav li', css: 'a { background-color: transparent; color: #FFFFFF; line-height: 13px; font-size: 11px; text-decoration: underline; cursor: pointer; } a:hover { color: #592b02; }', wmode: 'transparent' }); (which seems logical to me), the list items are not rendered at all. Could you please give me an advice how to do it correctly with the structure given? Thanks, Roman

  • MVC4 dynamically changing master layout page doesn't work on first load

    - by Kelvin
    I have an MVC4 mobile project that I want to add a desktop (non mobile) page to for some users. I have added a new desktop master page and assigned my view to use it. The first time I navigate to the page it renders using jquerymobile which appears to somehow be cached from the previous screen. If I hit F5 to refresh the page it displays using the assigned desktop masterpage correctly. Can anyone tell me how to fix this? Any insight appreciated

  • Getting Paperclip to work in Rails

    Hi Everyone, I have installed the Paperclip plugin to attempt to upload an avatar for my kase model.

  • Normalizing URI to make it work correctly with MakeRelativeUri

  • Chrome extensions: Content script (jQuery) in Youtube does not work properly

    - by Fabian
    I have this: $(document).ready(function() { $("button.yt-uix-expander-arrow").attr("id", "yt-uix-expander-arrow"); $("#yt-uix-expander-arrow").mouseover(function() { alert("Hello"); }); }); injected into Youtube. Using right click inspect element, the <button class="yt-uix-expander-arrow"> has a id="yt-uix-expander-arrow" attribute successfully added to it. However the mouseover event does not trigger. However if I were to change $("#yt-uix-expander-arrow").mouseover() to $(".yt-uix-expander-arrow").mouseover() it works. That's very unusual, because the #yt-uix-expander-arrow id has already been added to the button element. I tested it out on Facebook, adding a id to a class and doing a mouseover() event on the ID and it works. Any idea?

  • Django-South introspection rule doesn't work.

    - by Ory Band
    I'm using Django 1.2.3 and South 0.7.3. I am trying to convert my app (named core) to use Django-South. I have a custom model/field that I'm using, named ImageWithThumbsField. It's basically just the ol' django.db.models.ImageField with some attributes such as height, weight, etc. While trying to ./manage.py convert_to_auth core I receieve South's freezing errors. I have no idea why, I'm Probably missing something... I am using a simple custom Model: from django.db.models import ImageField class ImageWithThumbsField(ImageField): def __init__(self, verbose_name=None, name=None, width_field=None, height_field=None, sizes=None, **kwargs): self.verbose_name=verbose_name self.name=name self.width_field=width_field self.height_field=height_field self.sizes = sizes super(ImageField, self).__init__(**kwargs) And this is my introspection rule, which I add to the top of my models.py: from south.modelsinspector import add_introspection_rules from lib.thumbs import ImageWithThumbsField add_introspection_rules( [ ( (ImageWithThumbsField, ), [], { "verbose_name": ["verbose_name", {"default": None}], "name": ["name", {"default": None}], "width_field": ["width_field", {"default": None}], "height_field": ["height_field", {"default": None}], "sizes": ["sizes", {"default": None}], }, ), ], ["^core/.fields/.ImageWithThumbsField",]) This is the errors I receieve: ! Cannot freeze field 'core.additionalmaterialphoto.photo' ! (this field has class lib.thumbs.ImageWithThumbsField) ! Cannot freeze field 'core.material.photo' ! (this field has class lib.thumbs.ImageWithThumbsField) ! Cannot freeze field 'core.material.formulaimage' ! (this field has class lib.thumbs.ImageWithThumbsField) ! South cannot introspect some fields; this is probably because they are custom ! fields. If they worked in 0.6 or below, this is because we have removed the ! models parser (it often broke things). ! To fix this, read http://south.aeracode.org/wiki/MyFieldsDontWork Does anybody know why? What am I doing wrong?

  • How to configure the roles in my tomcat application to work with JNDI(WIN AUTH)

    - by Itay Levin
    Hi, I'm trying to change the authentication mode of my application from JDBC-REALM to JNDI-REALM. I configured the following section inside the Server.xml <Realm className="org.apache.catalina.realm.JNDIRealm" debug="99" connectionURL="ldap://****:389/DC=onsetinc,DC=com??sAMccountName?sub?(objectClass=*)" connectionName="[email protected]" connectionPassword="password" userBase="CN=Users" referrals="follow" userSearch="(sAMAccountName={0})" userSubtree="true" roleBase="CN=Users" roleName="name" roleSubtree="true" roleSearch="(member={1})"/> I have also configured the web.xml under my appfolder to contain the following: <security-role> <role-name>Admin</role-name> </security-role> <security-role> <role-name>WaterlooUsers</role-name> </security-role> <security-constraint> <web-resource-collection> <web-resource-name>Tube</web-resource-name> <url-pattern>/ComposeMessage.jsp</url-pattern> <url-pattern>/PageStatus.jsp</url-pattern> <url-pattern>/UserStatus.jsp</url-pattern> <url-pattern>/SearchEC.jsp</url-pattern> <url-pattern>/SearchEC2.jsp</url-pattern> <url-pattern>/SearchMessageStatisticsEC.jsp</url-pattern> <url-pattern>/SearchMessageStatus.jsp</url-pattern> <url-pattern>/SearchMessageStatisticsPager.jsp</url-pattern> <url-pattern>/SearchPageStatus.jsp</url-pattern> </web-resource-collection> <auth-constraint> <role-name>WaterlooUsers</role-name> </auth-constraint> </security-constraint> In my Active directory i have created a new group called WaterlooUsers It's distinguish name is : distinguishedName: CN=WaterlooUsers,CN=Users,DC=onsetinc,DC=com It has a property member which contains the following user: member: CN=Itay Levin,CN=Users,DC=onsetinc,DC=com (which is my user) My record on the active directory looks like that: sAMAccountName: itayL distinguishedName: CN=Itay Levin,CN=Users,DC=onsetinc,DC=com memberOf: CN=WaterlooUsers,CN=Users,DC=onsetinc,DC=com and when i get the popup for user/password i enter the username "ItayL" in the authentication message box (and my password) I have 2 questions: How do i configure correctly the roles parameters correctly in the Realm section in the server.xml to enable me to both authenticate and authorize both this group of users WaterlooUsers and also assign them to the appropriate role so that they can see all the relevant pages in my website. - currently it seems that all the Users in my domain are authenticated to the site but get the http-403 Error and can't access any of the pages in the site. I also want to be able to create 2 different set of roles in my site - which can both have access to the same pages - but will see different things on the page. (for instance adding some administrative ability to the admin) Hope it was clear enough and not too long. Thanks in advance, Itay

  • Servlet 3.0 logout doesn't work

    - by Kevin
    I've got a problem with the authentication features of Servlet 3.0: With this code in a Servlet v3: log.info(""+request.getUserPrincipal()); log.info(""+request.getAuthType()); log.info("===^==="); request.logout() ; log.info(""+request.getUserPrincipal()); log.info(""+request.getAuthType()); request.authenticate(response) ; log.info("===v==="); log.info(""+request.getUserPrincipal()); log.info(""+request.getAuthType()); I would always expect to see the Username/login windows, because of the logout() function. Instead, it seems to be a 'cache' mechanism which repopulate the credential and cancel my logout ... Admin BASIC ===^=== null null ===v=== Admin BASIC Is it a problem with my firefox, or something I'm missing in the Servlet code?

  • Reusing Object does not work properly

    - by balexandre
    Hi guys, I'm reusing a created Object just to change a Date and the ordinal value, but at the end I get 6 objects exactly as the last. in other words, I'm adding the object as a Reference and I should add as a Value What should I inherit my Object to have the Copy() method ? RecurringPayment rp, copy; rp = new RecurringPayment { ... } payments.Add(rp); // add first object copy = rp; // Copy the original element for (int i = 1; i <= 5; i++) { copy.NextPaymentDate = copy.NextPaymentDate.AddDays(copy.RecurringTime * 7); copy.OrderOrdinal = copy.OrderOrdinal + 1; payments.Add(copy); // add 5 more with X weeks ahead } Thank you

  • How to do pointer work with accessor methods in Objective-C

    - by Jasconius
    Basic problem statement: I have a very good reason for doing some pointer fanciness in an app where I need to pass a decimal by reference. So I have a class which stores many a decimal, so let's say is has a property as such: @property (nonatomic) double myDecimalValue; I want to pass it by reference to some other class. [someOtherObject sendMyDecimalByReference:&myDecimalValue]; But, a problem emerges! The way that actually has to be written (because it's a property) is [someOtherObject sendMyDecimalByReference:&decimalOrigin.myDecimalValue]; This fails to compile in objective-c I get around it by writing the following - (double *) myDecimalValueRef; [someOtherObject sendMyDecimalByReference:[decimalOrigin myDecimalValue]]; Except I have dozens of these decimals and I don't want to write that stupid wrapper function for every value. Is there a shorthand way to do this in Objective-C using just the Getter functions? Let's just assume I have a great reason for not using NSNumber. Thanks!

  • How to make TinyMCE work inside an UpdatePanel?

    - by lucian.jp
    I'm trying to do something that many people seem to have been able to do but which I am unable to implement any solution. The TinyMCE control works pretty well in an asp.net form until you enclose it with an UpdatePanel, which then breaks after postback. I have tried some fixes like the RegisterClientScriptBlock method, but am still unsuccessful, I still lose the tinyMCE control after postback. Below is a full test project (VS 2008) provided with a Control outside UpdatePanel and one inside, with a button on each to generate postback. Also in the project I have a EditorTest control which include commented code of some calls I tried, in case it gives anyone any ideas. CODE SAMPLE Here are some sources for some solutions on the MCE forum : AJAX UpdatePanel

  • jQuery in Opera User JS Doesn't Work

    - by Axonn
    Hello ::- ). I'm playing with some Opera User JS. I included "1jquery.min.js" in my User JS folder (1 in front because Opera loads them alphabetically). Unfortunately, it doesn't appear to be working. window.onload = OnWindowLoad; $(document).ready(function() { alert ($('#area_19')); }); function OnWindowLoad () { alert ($('#area_19')); alert(document.getElementById("area_19")); } What's interesting about this code is that the first two alerts come back in NULL, but the last one does find the object! So the element definitely exists in the page, but my jQuery seems unable to get it. What's even stranger is that the jQuery "ready" function works, indicating that I do have jQuery capability. I'm quite puzzled about all this ::- /. Hopefully somebody can give me a clue ::- ).

For instance the UIToolBar is not at the correct position. So here is the question: If you don't use UITableViewController or any other Controller, that takes care of all the positioning and sizing, then you have to do it yourself. Can someone someone tell me how this works? What do I need to understand?

  • Sort on DataView does not work if DataTable has zero rows

    - by BigBlondeViking
    We have a WPF app that has a DataGrid insode a ListView. private DataTable table_; We do a bunch or dynamic column generation ( depending on the report we are showing ) We then do the a query and fill the DataTable row by row, this query may or may not have data.( not the problem, an empty grid is expected ) We set the ListView's ItemsSource to the DefaultView of the DataTable. lv.ItemsSource = table_.DefaultView; We then (looking at the user's pass usage of the app, set the sort on the column) Sort Method below: private void Sort(string sortBy, ListSortDirection direction) { var dataView = CollectionViewSource.GetDefaultView(lv.ItemsSource); dataView.SortDescriptions.Clear(); var sd = new SortDescription(sortBy, direction); dataView.SortDescriptions.Add(sd); dataView.Refresh(); } In the Zero DataTable rows scenario, the sort does not "hold"? and if we dynamically add rows they will not be in sorted order. If the DataTable has at-least 1 row when the sort is applied, and we dynamically add rows to the DataTable, the rows com in sorted correctly. I have built a standalone app that replicate this... It is an annoyance and I can add a check to see if the DataTable was empty, and re-sort... Anyone know whats going on here, and am I doing something wrong? FYI: What we based this off if comes from the MSDN as well: http://msdn.microsoft.com/en-us/library/ms745786.aspx

  • How is IObservable<double>.Average supposed to work?

    - by Dan Tao
    Update Looks like Jon Skeet was right (big surprise!) and the issue was with my assumption about the Average extension providing a continuous average (it doesn't). For the behavior I'm after, I wrote a simple ContinuousAverage extension method, the implementation of which I am including here for the benefit of others who may want something similar: public static class ObservableExtensions { private class ContinuousAverager { private double _mean; private long _count; public ContinuousAverager() { _mean = 0.0; _count = 0L; } // undecided whether this method needs to be made thread-safe or not // seems that ought to be the responsibility of the IObservable (?) public double Add(double value) { double delta = value - _mean; _mean += (delta / (double)(++_count)); return _mean; } } public static IObservable<double> ContinousAverage(this IObservable<double> source) { var averager = new ContinuousAverager(); return source.Select(x => averager.Add(x)); } } I'm thinking of going ahead and doing something like the above for the other obvious candidates as well -- so, ContinuousCount, ContinuousSum, ContinuousMin, ContinuousMax ... perhaps ContinuousVariance and ContinuousStandardDeviation as well? Any thoughts on that? Original Question I use Rx Extensions a little bit here and there, and feel I've got the basic ideas down. Now here's something odd: I was under the impression that if I wrote this: var ticks = Observable.FromEvent<QuoteEventArgs>(MarketDataProvider, "MarketTick"); var bids = ticks .Where(e => e.EventArgs.Quote.HasBid) .Select(e => e.EventArgs.Quote.Bid); var bidsSubscription = bids.Subscribe( b => Console.WriteLine("Bid: {0}", b) ); var avgOfBids = bids.Average(); var avgOfBidsSubscription = avgOfBids.Subscribe( b => Console.WriteLine("Avg Bid: {0}", b) ); I would get two IObservable<double> objects (bids and avgOfBids); one would basically be a stream of all the market bids from my MarketDataProvider, the other would be a stream of the average of these bids. So something like this: Bid Avg Bid 1 1 2 1.5 1 1.33 2 1.5 It seems that my avgOfBids object isn't doing anything. What am I missing? I think I've probably misunderstood what Average is actually supposed to do. (This also seems to be the case for all of the aggregate-like extension methods on IObservable<T> -- e.g., Max, Count, etc.)
