  • Dialog is not defined

    - by Clay McClure
    I'm building my first Facebook Connect application, and am running into an odd problem. This example code: <script type="text/javascript" charset="utf-8"> FB.init("{{ FACEBOOK_API_KEY }}", "{% url xd_receiver %}"); FB.ensureInit(function() { var invite_dialog; function showInviteDialog() { invite_dialog = new Dialog(Dialog.DIALOG_POP).showMessage('Share with Friends', invite_friends_selector, null, null); } function hideInviteDialog() { invite_dialog.hide(); } showInviteDialog(); }); </script> keeps throwing the error: Dialog is not defined Is Dialog available in Facebook connect/XFBML applications? Do I need to do anything special in order to use it? Thanks in advance!

  • jQuery event.stopPropagation is not working on <a>

    - by HorusKol
    I have the following javascript: $('#ge-display').click(function (event) { window.open('/googleearth/ge-display.php','','scrollbars=yes,menubar=no,height=650,width=1000,resizable=yes,toolbar=yes,location=no,status=no'); event.stopPropagation(); return false; }); the element with id 'ge-display' is a standard link: <a href="/googleearth/ge-display.php" id="ge-display" target="_blank">Load Google Earth Plugin (in a new window)</a> The problem is - when I take out the 'return false;' line from the click event handler, the javascript popup opens, and then another browser window opens - I thought stopPropagation() would prevent the links own click handler? I've also tried stopImmediatePropagation() - but I still need to return false to stop the default behaviour of the link.

  • Is generic Money<TAmount> a good implementation idea?

    - by jdk
    I have a Money Type that allows math operations and is sensitive to exchange rates so it will reduce one currency to another if rate is available to calculate in a given currency, rounds by various methods. It has other features that are sensitive to money, but I need to ask if the basic data type used should be made generic in nature. I've realized that the basic data type to hold an amount may differ for financial situations, for example: retail money might be expressed as all cents using int or long where fractions of cents do not matter, decimal is commonly used for its fixed behaviour, sometimes double seems to be used for big finance and large values sometimes a special BigInteger or 3rd-party type is used. I want to know if it would be considered good form to turn Money into Money<T_amount> so it can be used in any one of the above chosen scenarios?

  • Generic Text Only printer driver mangles control codes

    - by Terry
    If an escape character (or most other characters < 0x20) is sent to the generic / text only printer it gets printed as a period. Using the code in the WinDDK is it possible to 'correct' this behaviour so that it passes it through unmodified? The general scenario for this is that some application ('user app') outputs a document to a windows printer. My application requires this data in plain text form and so what I do is run a generic / text only printer that talks to a virtual com port. This generally works fine except where the 'user app' outputs binary data to the print queue without using the correct mechanism (which seems to work fine on some printer drivers, such as the Epson POS ones, but not the generic / text only one). I've tried changing the print processor selection without success and also tried looking at the gtt files to see if I could readily map in these characters as though they were printable, but the minidriver tool won't let me do that. Any suggestions?

  • Visual Studio 2010 does not discover new unit tests

    - by driis
    I am writing some unit tests in Visual Studio 2010. I can run all tests by using "Run all Tests in Current Context". However, if I write a new unit test, it does not get picked up by the environment - in other words, I am not able to find it in Test List Editor, by running all tests, or anywhere else. If I unload the project and then reload it; the new test is available to run. When I am adding a unit test, I simply add a new method to an already existing TestClass and decorating it with [TestMethod] attribute - nothing fancy. What might be causing this behaviour, and how do I make it work ?

  • Customize WPF databinding: How to add custom logic?

    - by Ashwani Mehlem
    Hi, i have a question regarding some complex data-binding. I want to be able to update a grid (which has the property "IsItemsHost" set to true) dynamically whenever a data-binding occurs. To be more specific, i bind the grid to some items and i want to change the number of grid rows depending on these items, add something like a header (one row containing some text), and set the items' Grid.Row and Grid.Column using some custom logic. What is the easiest way to apply such behaviour whenever the bound data is updated? Do i have to use a viewmodel that also contains the header data? Thanks in advance.

  • Add jar to EAR in Eclipse

    - by Gerard
    I have several projects in an EAR in Eclipse. These projects themselves have dependency jar's on the build path marked as "do not export, do not contribute to others". Now in Eclipse I add jar's to the EAR via the EAR properties "Java EE Module Dependencies". I browse to the jar (add jar) and click ok. The jar is added to the list. When I click apply, the added jar is gone from the list, it cannot be found in other properties, it is contained in the hidden folder .settings in the file org.eclipse.wst.common.component. This behaviour does not make much sense to me, what am I missing?

  • How to debug .net error where message is masked in Ajax call

    - by Matt Thrower
    Hi, I'm currently working on a page which makes use of the MS Ajax UpdatePanel. However I've run into a strange problem. If I simply compile and view my page, one of the button click events results in an error. However, because the button affects items inside an UpdatePanel the actual exception is hidden from me: all I'm getting is a HTTP 500 error returned to me through the UpdatePanel Javascript. What's odd about this is that if I step through the code line by line in Visual Studio, I don't get the error. The button doesn't cause the behaviour I'm expecting, but it throws no errors. Because the step through isn't causing an error to be thrown, I'm at a loss how I can get to the actual exception message so I can find out where the error is being thrown and debug it. Suggestions gratefully received. Cheers, Matt

  • cgi.FieldStorage translating unicode strangely

    - by trydyingtolive
    I have a form that is on a UTF-8 encoded page. When I submit the form cgi.FieldStorage converts any non-ascii character to an odd format. For example if I submit the value c. The browser will send %c4%87. I want to convert that to the string \xc4\x87. However, cgi.FieldStorage is converting it to \\xc4\\x87. post = cgi.FieldStorage(fp=env['wsgi.input'], environ=env, keep_blank_values=True) Python 2.6 on Ubuntu 9.10SE, Apache2, mod_wsgi.

  • Someone is using the struct name as a variable name too. What does the code really say? (c++)

    - by EvilTeach
    This morning we found an old chunk of code that was causing a library call to crash. struct fred { int a; int b; int c; }; fred fred[MAX_SIZE+1]; memset( fred, 0, sizeof(fred) * MAX_SIZE+1 ); It appears that the sizeof(fred) may have been the full array size, rather than the structure size, as it was overwriting a great deal of memory. The fact that it compiled without warning on several different systems seemed odd. Is there a correct semantic for this case where the type and variable name are colliding? or is this some sort of undefined behavior? or just a defect? I haven't been been clever enough to find anything on Google or our language help. Thanks Evil

  • database design question

    - by Leonardo
    Hi all, I am building a database as a simple exercise, it could be hosted on any database server, so I am trying to keep things as much standard as possible. Basically what I would like to do is a 'code' table that get referenced by other entities. I explain: xcode id code r role p property code r admin r staff p title .... then I would like to have some view like: role (select * from code where xcode='r') r admin r staff property (select * from code where xcode='p') p title then, suppose we have an entity myentity id - 1 role - admin (foreign key to role) title - title (foreign key to property) Obviously I cannot create foreign key to a view, but this is to tell the idea I have in mind. How can I reflect such behaviour using whenever possible, standard sql syntax, then as a second option, database additional features like trigger ecc... ? Because if I tell that role and title in myentity are foreign key to 'code', instead of the views, nothing would stop me to insert a role in title field. thanks Leonardo

  • Is anyone else experiencing weird debug + crash behavior with Silverlight?

    - by Scott Barnes
    I have noticed that after awhile of debug/tweakcode/debug etc that eventually Silverlight starts to crash all of my browsers (i.e. doesn't matter which i fire, they all just crash). If i then go to a site that has Silverlight, it works fine? so it has something to do with debugger + Silverlight not getting along? I then reboot and the problem goes away? Is anyone else experiencing this kind of weird behaviour? I have noticed though that if i put breakpoints on the code they all seem to halt, in that it appears that it can instantiate the said .xap etc ok, but just can't seem to render it to screen without a crash? (There's nothing in the log files and i've tried to attach a seperate VS2008 instance to both IE, Devenv and Blend etc trying to see if i can catch what's causing this to occur?)

  • Animating the <li> removal in jQuery

    - by Marco
    Hi guys, i'm adding and removing <li> elements with jQuery, that are shown horizontally with the following style: #my_ul { list-style: none; } #my_ul li { float: left; margin: 0px 15px; } For example, if i add four <li> to an <ul> and then i decide to remove the second one, after it has been removed the other two <li> elements on the right immediately move to the left. What i'd like to do is to animate this behaviour, with the remaining <li> elements that softly moves to the left. Any tips? Thanks

  • Scroll UITableView so that the header isn't visible

    - by DASKAjA
    I've got a UITableView with a UISearchBar as the tableViews.tableHeaderView. Just like the new Mail.app, Notes.app, etc. in 3.0. I want to hide the SearchBar until the user drags it in his sight. My attempt only works when there're a couple of items in the tableView, so that the tableView actually wants to scroll. I call this in loadView: NSIndexPath *indexPath = [NSIndexPath indexPathForRow:0 inSection:0]; [self._tableView scrollToRowAtIndexPath:indexPath atScrollPosition:UITableViewScrollPositionTop animated:NO]; Nevertheless it seems that Apple handles such a serachbar differently. After draging out the searchbar it doesn't seem to be bounded to the tablecells anymore (in Notes.app, not in Mail.app). But perhaps Apple has a distinct method for that new 3.0 behaviour, and I just can't find it?

  • Automating Portlet Deployment to WebSphere Portal Server 6.1

    - by GaZ
    I've recently started on a project to develop some portlets which will run on IBM WebSphere Portal Server 6.1. Does anyone know of any scripts, Ant tasks, Maven plugins, etc. for publishing a portlet to Portal Server? In the WebSphere Portlet Factory plugin for eclipse it is possible to "publish" a portlet project to Portal Server instance, however I'd like to know what's going on underneath the hood here (or at least how to replicate the behaviour) so that I can do it in other places (i.e. from continuous integration server). UPDATE: From what I've read it sounds like the Portlet Factory publishes using a WebSphere JMX client. Does anyone know where I can find more details on this?

  • gradle runJar task?

    - by Misha Koshelev
    Dear All: I am trying to make a task to run my Jar file in gradle. I have come up with the following: task runJar(dependsOn:[jar]){ ant.java(jar:,fork:true) } However, I am unable to find the path to the jar file. Any help much appreciated. Thank you! Misha EDIT: OK this is rather odd. This task runs before compile, etc.??? EDIT: Fixed. The key is in a doLast { } notation, or, in shorthand task runJar(dependsOn:"jar")<<{ ant.java(jar:"${libsDir}${File.separator}${archivesBaseName}.jar",fork:true) } Misha

  • Inheriting from class that inherits from DynamicObject

    - by SeveQ
    Hello there, I'm experimenting with C# 4.0's dynamic object model. I've created an abstract class named "Block" that inherits from DynamicObject. It overrides TryGetMember and TrySetMember. Furthermore I've created a usable class named "Brush" that inherits from "Block". I want it to be usable dynamically. But when I create a dynamic object from it and try to access a runtime bound member, it pelts me with an exception telling me that the member doesn't exist. The overridden TryGetMember or TrySetMember methods of the abstract parent class aren't getting called. Is this behaviour to be expected? Thank you!

  • How should jruby-jars and jruby-rack be added to the classpath using warbler?

    - by Ben Hogan
    Hi again, I've been reading through the warbler source code, and I can't figure out how the jruby-jars and jruby-rack jars are meant to end up on the servlet classpath? It seems warbler is copying them into web-inf/gems/gems/<gemname>/lib/<jarname>.jar but they are not on the classpath. I'm guessing that if I put them in my ruby apps lib/ folder they would be copied to web-inf/lib and all would be well, however, it seems odd to have 2 copies of the jar in the war file, is that what I am meant to do?

  • Visualize the depth buffer

    - by Thanatos
    I'm attempting to visualize the depth buffer for debugging purposes, by drawing it on top of the actual rendering when a key is pressed. It's mostly working, but the resulting image appears to be zoomed in. (It's not just the original image, in an odd grayscale) Why is it not the same size as the color buffer? This is what I'm using the view the depth buffer: void get_gl_size(int &width, int &height) { int iv[4]; glGetIntegerv(GL_VIEWPORT, iv); width = iv[2]; height = iv[3]; } void visualize_depth_buffer() { int width, height; get_gl_size(width, height); float *data = new float[width * height]; glReadPixels(0, 0, width, height, GL_DEPTH_COMPONENT, GL_FLOAT, data); glDrawPixels(width, height, GL_LUMINANCE, GL_FLOAT, data); delete [] data; }

  • Differences Between Java and HTML5 -- Squeezed Background

    - by ashes999
    I noticed some (slightly disturbing) differences between the HTML5 and the Java versions of the playN showcase (source). (I just downloaded everything yesterday, so presumably I'm running the latest samples.) Specifically, two flaws I noticed in the HTML5 version: The text on the buttons is quite blurry (not anti-aliased, but actually blurry) compared to the Java version The background in the "Swirl" sample is restricted to one corner of the app; it doesn't cover the entire visible space the way it does in the Java version. Are these bugs, or the expected behaviour?

  • How to send EOF to stdin in paramiko?

    - by Alexandru
    I would like to execute some program through ssh and redirect its input from a file. The behaviour of the following code: channel.exec_command('cat') with open('mumu', 'r') as f: text = f.read() nbytes = 0 while nbytes < len(text): sent = channel.send(text[nbytes:]) if sent == 0: break nbytes += sent should be equivalent to (assuming public-key authentication): ssh user@host cat < mumu However the application hangs waiting for more input. I think this happens because the stdin stream is never closed. How do I do that?

  • MouseOver Trigger firing on ContextMenu with overridden ControlTemplate. Where is it coming from?

    - by Dabblernl
    I have this very simple ControlTemplate: <ControlTemplate TargetType="{x:Type ContextMenu}"> <Border Name="Border" Background="{StaticResource BlueBackground}" BorderBrush="LightBlue" CornerRadius="10" BorderThickness="1" > <StackPanel IsItemsHost="True"/> </Border> </ControlTemplate> I made it to create a nifty jawdroppingly beautiful rounded corner! However, when I point the mouse over a contextmenu a MouseOver Trigger fires from somewhere that draws a terribly ugly nearly square border on top of my nifty rounded border! Where is it coming from?? EDIT: The most likely cause is that the ContextMenu is an ItemsControl that holds MenuItems, even when my ContextMenu holds a single UserControl. So the UserControl is seen as a MenuItem and highlighted when the IsMouseOver==true! What is the easiest way to disable this behaviour?

  • C# UserControl factory

    - by user1112111
    Let's say you have two classes that extend UserControl. Each of the controls provides a custom event (this could be done by using an interface). You want to display one of the controls in the odd days and the other in the even days. You also want to be able to drag&drop (Visual Studio) the UserControl on your form without knowing what the Control type will finally be. How do you do that ? Is the factory pattern useful here ?

  • Uploadify refuses to upload WMV, FLV and MP4 files - SOLVED

    - by Jon Winstanley
    The uploadify plugin for JQuery seems very good and works for most file types. However, it allows me to upload all file types apart from the ones I need! Namely .WMV, .FLV and .MP4 Uploads of any other type work. I have already tried changing the fileExt parameter and also tried removing it altogether. I have testing in Google Chrome, IE7 and Firefox and none work for these file types. I have a ton of local projects already and uploading is not an issue on any other project, I even use the same example files (This is the first time I have used Uploadify) Is there a known reason for this behaviour? EDIT: Have found the issue. I had forgotten to add my usual .htaccess file to the example project.

  • Django foreign keys cascade deleting and "related_name" parameter (bug?)

    - by Wiseman
    In this topic I found a good way to prevent cascade deleting of relating objects, when it's not neccessary. class Factures(models.Model): idFacture = models.IntegerField(primary_key=True) idLettrage = models.ForeignKey('Lettrage', db_column='idLettrage', null=True, blank=True) class Paiements(models.Model): idPaiement = models.IntegerField(primary_key=True) idLettrage = models.ForeignKey('Lettrage', db_column='idLettrage', null=True, blank=True) class Lettrage(models.Model): idLettrage = models.IntegerField(primary_key=True) def delete(self): """Dettaches factures and paiements from current lettre before deleting""" self.factures_set.clear() self.paiements_set.clear() super(Lettrage, self).delete() But this method seems to fail when we are using ForeignKey field with "related_name" parameter. As it seems to me, "clear()" method works fine and saves the instance of "deassociated" object. But then, while deleting, django uses another memorized copy of this very object and since it's still associated with object we are trying to delete - whooooosh! ...bye-bye to relatives :) Database was arcitectured before me, and in somewhat odd way, so I can't escape these "related_names" in reasonable amount of time. Anybody heard about workaround for such a trouble?
