• UIView added with incorrect orientation

  - by mx12

  So I have been working on a problem with UIView on the iPad. Essentially I have a splitview as the root view and I want to overlay my custom image view over top of the splitview (This is because the splitview must be the root view). The problem that I have, is when I call addSubview on my splitview the subview gets displayed in its default orientation, with no regard to the iPad's current orientation. Any suggestions on what I am doing wrong or flag I am not setting? Thanks! Code that I am using to add the view: [splitViewController.view addSubview: myImageController.view]; Example screenshots: http://www.engineering.uiowa.edu/~krtaylor/so/

• copy child collection to another object

  - by Bogdan

  Hi everyone, I have a one-to-many relationship between Part and Params (a "Part" has many "Params). I'm trying to do something naive like this: Part sourcePart = em.find(Part.class, partIdSource); Part destPart = em.find(Part.class, partIdDest); Collection<Param> paramListSource = sourcePart.getParamList(); destPart.setParamList(paramListSource); Basically I want to copy all the parameters from sourcePart to destPart. Hopefully the persistence provider will automatically set the right foreign keys in the Param table/entity. The above code will obviously not work. Is there any easy way of doing this, or do I have to do create a new collection, then add each Param (creating new Param, setting attributes, etc) ?

• Service Broker not working after database restore

  - by roryok

  Have a working Service Broker set up on a server, we're in the process of moving to a new server but I can't seem to get Service Broker set up on the new box. Have done the obvious (to me) things like Enabling Broker on the DB, dropping the route, services, contract, queues and even message type and re adding them, setting ALTER QUEUE with STATUS ON SELECT * FROM sys.service_queues gives me a list of the queues, including my own two, which show as activation_enabled, receive_enabled etc. Needless to say the queues aren't working. When I drop messages into them nothing goes in and nothing comes out. Any ideas? I'm sure there's something really obvious I've missed...

• set and get variables throughout moive - actionscript 3

  - by ed209

  I need to set various variables depending on what a user clicks. Those variables then need to be accessed by other movieclips. The problem is that at the time of clicking, those "other movieclips" don't exist on the timeline yet. What I have done is assign the variable to the parent movieclip, although I guess I could just as easily set them to the root. Then I would grab that value when the relevant clip is initiated. // set - works MovieClip(parent).aMovieClip.someVariable = myVal; // get? - doesn't work getVar = MovieClip(parent).aMovieClip.someVariable; the above doesn't work - what is the correct way to get that value whenever I need it. I guess it's a case of getting and setting global variables

• Automatically "upgrade" user settings from previous version of app.config file?

  - by SqlRyan

  Every time I compile my app and the version number changes (I have an auto-incrementing build number), I lose the user-configured app.config settings, since they're stored in the AppData folder for a specific version. Essentially, every release of my application starts from scratch as far as user settings go. While this is a mild annoyance in development, it raises the question as I approach deployment/release - if I use the app.config to store my user settings, will the user's personalized settings be hosed every time they install a patch that changes the version number of my app? If so, is there an easy way to "upgrade" the settings from the previous release? I know that using HKCU in the registry is another option, but I like the ease of the My.Settings namespace, and I'd like to stay with app.config. Another SO question asks something similar, though the answer doesn't seem that clear. Will setting my MSI so it asks the user to upgrade be enough to preserve these user-level settings?

• Disable Link while animated Basket

  - by Dante

  Hi, I'm using this script for my online shopping basket: http://www.webresourcesdepot.com/fly-to-basket-effect-with-jquery/. Like people suggest in the comments it's easy buggy when you click multiple times on the same image. How can I disable the img link when it's clicked once and re-enable it when the product is added to the basket? I've tried setting the attribute HREF of to # in the beginning of the function, but that doesn't help. So when a user clicks the function needs to be executed, but the link should be disabled as long as the function is busy. thanks in advance for your help.

• Reading file data during form's clean method

  - by Dominic Rodger

  So, I'm working on implementing the answer to my previous question. Here's my model: class Talk(models.Model): title = models.CharField(max_length=200) mp3 = models.FileField(upload_to = u'talks/', max_length=200) Here's my form: class TalkForm(forms.ModelForm): def clean(self): super(TalkForm, self).clean() cleaned_data = self.cleaned_data if u'mp3' in self.files: from mutagen.mp3 import MP3 if hasattr(self.files['mp3'], 'temporary_file_path'): audio = MP3(self.files['mp3'].temporary_file_path()) else: # What goes here? audio = None # setting to None for now ... return cleaned_data class Meta: model = Talk Mutagen needs file-like objects - the first case (where the uploaded file is larger than the size of file handled in memory) works fine, but I don't know how to handle InMemoryUploadedFile that I get otherwise. I've tried: # TypeError (coercing to Unicode: need string or buffer, InMemoryUploadedFile found) audio = MP3(self.files['mp3']) # TypeError (coercing to Unicode: need string or buffer, cStringIO.StringO found) audio = MP3(self.files['mp3'].file) # Hangs seemingly indefinitely audio = MP3(self.files['mp3'].file.read()) Is there something wrong with mutagen, or am I doing it wrong?

• Drupal - Use lightbox with Views (Rel attribute) - in output link

  - by kilrizzy

  In Drupal I have two image fields, one to act as a thumbnail and the other the image that will open when the thumbnail is clicked. The only way I could find to link the two was to use the option for "Output this field as a link" and link to the image field. This works, so when I click the thumbnail it opens the larger image however I would like to use lightbox2 for this task but in the "Output this field as a link" options there is no way to set the "rel" attribute. Is there a way to either set the rel attribute or invoke the lightbox by setting a class?

• jQuery $.data(): Possible misuse?

  - by Rosarch

  Perhaps I'm using $.data incorrectly. Assigning the data: var course_li = sprintf('<li class="draggable course">%s</li>', course["fields"]["name"]); $(course_li).data('pk', course['pk']); alert(course['pk']); // shows a correct value Moving the li to a different ul: function moveToTerm(item, term) { item.fadeOut(function() { item.appendTo(term).fadeIn(); }); } Trying to access the data later: $.each($(term).children(".course"), function(index, course) { var pk = $(course).data('pk'); // pk is undefined courses.push(pk); }); What am I doing wrong? I have confirmed that the course li on which I am setting the data is the same as the one on which I am looking for it. (Unless I'm messing that up by calling appendTo() on it?)

• Get label height for fixed width

  - by Jonas

  Is there any way I can get the height of a label, if it hypothetically had a certain width? I've been trying with control.GetPreferredSize(size) like so: Dim wantedWidth as Integer = 100 dim ctrlSize as Size = label.GetPreferredSize(new Size(wantedWidth, 0)) because I thought that setting height = 0, would indicate a free height, but the height I get is way too small. I also tried to estimate the height of the label, using Graphics.MeasureString to calculate the equivalent area of the Label dim prefWidth as Integer = 100 dim estSize as SizeF = g.MeasureString(label.Text, label.Font) dim estHeight as Integer = (Integer)(estSize.Width * estSize.Height / prefWidth) but that yields the same result. Any ideas? I'm on .NET 2.0, unfortunately.

• Image Preloading in Canvas

  - by smokinguns

  I'm drawing an Image on the canvas using the drawImage function. This is how Im setting the src property of the image: var img = new Image(); // Create new Image object img.src = 'test.php?filename=myfile.jpg' and then oCanvas.width = 600; oCanvas.height = 400; oContext.drawImage(img, 0, 0, 600, 400); The problem is that if the src isn't set then I get the foll error:"uncaught exception: [Exception... "Component returned failure code: 0x80040111 (NS_ERROR_NOT_AVAILABLE) [nsIDOMCanvasRenderingContext2D.drawImage]" . I know I get this error coz the image hasnt finished loading. I added an alert just before the call to drawImage function to let the image finish loading and it seems to work. But it's a pain in the neck. How do I check if the image has finished loading? BTW I have to set the src property by calling a php file.

• How to override JS function from a firefox extension?

  - by BruceBerry

  Hello, I am trying to intercept calls to document.write for all pages. Setting up the interception inside the page by injecting a script like function overrideDocWrite() { alert("Override called"); document.write = function(w) { return function(s) { alert("special dom"); w.call(this, wrapString(s)); }; }(document.write); alert("Override finished"); } is easy and works, but i would like my extension to setup the interception for each document object from inside the extension. I couldn't find a way to do this. I tried to listen for the "load" event and set up the interception there but it also fails. How do I hook calls to doc.write from an extension?

• Fix internal links in JS

  - by FB55

  I just created a script which extracts the article out of a webpage via server-side JS. (If your interested: it's used for http://pipes.yahoo.com/fb55/expandr .) I just got a little problem with internal links. Some pages include links like: /subfolder/subpage.html What I would need to do is fixing them and setting there root, like this: protocol://secondlevel.firstlevel/subfolder/subpage.html I'm using E4X for processing the page. I don't want to show my current creepy try, it's buggy and slow. Does anybody have a solution for me?

• WPF: Hidden parent and visible child

  - by oakskc

  As of last night, I decided to start learning about WPF and have been reading through a number of online tutorials and books. This is a huge shift. One feature that has fascinated me is the implicit property value inheritance. I know in the WinForms world, if a control is not visible then neither are any of the child controls. Same seems to be true in the WPF world, as expected. I wondered if explicitly setting the child control's Visibility property would allow for an invisible parent and visible child and it did not. Is this something that would be possible in WPF? Can you have a container control that is hidden with visible children? This is more an exercise of curiosity than anything. I'm still trying to wrap my head around a lot of what I've been reading.

• How can I get the edit control in a cell of a DataGridView to validate itself?

  - by Stuart Helwig

  It appears that the only way to capture the keypress events within a cell of a DataGridView control, in order to validate user input as they type, is to us the DataGridView controls OnEditControlShowing event, hook up a method to the edit control's (e.Control) keypress event and do some validation. My problem is that I've built a heap of custom DataGridView column classes, with their own custom cell types. These cells have their own custom edit controls (things like DateTimePickers, and Numeric or Currency textboxes.) I want to do some numeric validation for those cells that have Numeric of Currency Textboxes as their edit controls but not all the other cell types. How can I determine, within the DataGridView's "OnEditControlShowing" override, whether or not a particular edit control needs some numeric validation? (In the meantime I've restorted to setting the Tag property of my custom edit controls to a known value and any Edit Controls I find in the OnEditControlShowing override, I hook to my validation routine - I don't like that much!)

• .NET 4.0 Debugging Behavior

  - by Jason

  We recently migrated to VS 2010. We installed .NET 4.0 on our test machine. When we execute a console application that throws an exception, we no longer see the exception message and stack trace printed to the console but instead see the message An unhandled win32 exception occurred in something.exe [PID]. Just-In-Time debugging this exception failed with the following error: No installed debugger has Just-In-Time debugging enabled. In Visual Studio, Just-In-Time debugging can be enabled from Tools/Options/Debugging/Just-In-Time. We do have the above setting enabled. What do we need to do to return to the behavior we had previously?

• How do I display the current value of an Android Preference in the Preference summary?

  - by nyenyec

  This must come up very often. When the user is editing preferences in an Android app, I'd like them to be able to see the currently set value of the preference in the Preference summary. Example: if I have a Preference setting for "Discard old messages" that specifies the number of days after which messages need to be cleaned up. In the PreferenceActivity I'd like the user to see: "Discard old messages" <- title "Clean up messages after x days" <- summary where x is the current Preference value Extra credit: make this reusable, so I can easily apply it to all my preferences regardless of their type (so that it work with EditTextPreference, ListPreference etc. with minimal amount of coding).

• How do I define the default background color for window instances in a shared ResourceDictionary?

  - by Nicholas

  I can't seem to set a default background color for all of my windows in my application. Does anyone know how to do this? Currently I'm setting a theme in my App.xaml file like this. <Application> <Application.Resources> <ResourceDictionary Source="Themes/SomeTheme.xaml" /> This basically styles my entire application. Inside of SomeTheme.xaml I am trying to set a default color for all of my windows like this. <Style TargetType="{x:Type Window}"> <Setter Property="Background" Value="{DynamicResource MainColor}" /> </Style> This syntax works on a type of Button, but is completely ignored for Window. What am I doing wrong? Is there something special I have to do for a Window type.

• how to configure hibernate not to update @Version on each access to entity

  - by radai

  i have a simple query that returns an entity, and when i look at hibernate SQL output i see that when i execute this query hibernate updates the @Version field (on each consecutive read the @version field is updated). i dont modify anything in the entity i fetch, and i dont pass is as an argument to either persist or merge. this effectively means every read i make turns into a read+write. i've tried setting the lock mode t oboth NONE (jpa 2) and READ (jpa 1) to no avail. is there any way to achieve this? if so, is there any way to set this as the default behavior in persistence.xml in some way ? im using jpa2 over hibernate 3.6

• How do I use multiple settings file in Django with multiple sites on one server?

  - by William Bing Hua

  I have an ec2 instance running Ubuntu 14.04 and I want to host two sites from it. On my first site I have two settings file, production_settings.py and settings.py (for local development). I import the local settings into the production settings and override any settings with the production settings file. Since my production settings file is not the default settings.py name, I have to create an environment variable DJANGO_SETTINGS_MODULE='site1.production_settings' However because of this whenever I try to start my second site it says No module named site1.production_settings I am assuming that this is due to me setting the environment variable. Another problem is that I won't be able to use different settings file for different sites. How do I start use two different settings file for two different websites?

• Unrecognized authentication type when doing an Auth to Exchange from Rails

  I'm getting this error when trying to authenticate with Exchange Server from Ruby on Rails: 504 5.7.4 Unrecognized authentication type config.action_mailer.raise_delivery_errors = true config.action_mailer.perform_deliveries = true config.action_mailer.delivery_method = :smtp config.action_mailer.smtp_settings = { :address => "x.x.x.x", :port => 25, :user_name => "xxdomain\xxuser", :password => "xxxxxx", :authentication => :login, :enable_starttls_auto => true } I've tried all sorts of combinations of configuration settings, including changing the settings to use "plain" authentication, adding the domain, setting enable_starttls_auto to true, false, and removing it entirely, removing the port. Nothing has worked. Any ideas?

• What is the effect on record size of reordering columns in PostgreSQL?

  - by Summer

  Since Postgres can only add columns at the end of tables, I end up re-ordering by adding new columns at the end of the table, setting them equal to existing columns, and then dropping the original columns. So, what does PostgreSQL do with the memory that's freed by dropped columns? Does it automatically re-use the memory, so a single record consumes the same amount of space as it did before? But that would require a re-write of the whole table, so to avoid that, does it just keep a bunch of blank space around in each record? Thanks! ~S

• Win32 script environment for testing http redirects?

  - by Anders Lindahl

  The past few days I've been working with setting up an Apache server on Windows. The server is supposed to host several .htaccess files, each redirecting (or, in some cases, proxying) to different hosts. I want to create tests for these redirectons, and the solution I'm currently considering is a CGI script running on the same server, sending GET requests to it and verifying that it gets the correct redirection headers back. A scripting solution (vscript/jscript) seems worth exploring, but so far I've only managed to rule out Microsoft.XMLHTTP because it follows the redirect "behind the scenes". Are there any libraries or other solutions already present on a reasonably standard Windows Server that can do this kind of low-level HTTP work? If not, any other suggestions of simple environments to set up for verifying redirects?

• How to do query auto-completion/suggestions in Lucene?

  - by Mat Mannion

  I'm looking for a way to do query auto-completion/suggestions in Lucene. I've Googled around a bit and played around a bit, but all of the examples I've seen seem to be setting up filters in Solr. We don't use Solr and aren't planning to move to using Solr in the near future, and Solr is obviously just wrapping around Lucene anyway, so I imagine there must be a way to do it! I've looked into using EdgeNGramFilter, and I realise that I'd have to run the filter on the index fields and get the tokens out and then compare them against the inputted Query... I'm just struggling to make the connection between the two into a bit of code, so help is much appreciated! To be clear on what I'm looking for (I realised I wasn't being overly clear, sorry) - I'm looking for a solution where when searching for a term, it'd return a list of suggested queries. When typing 'inter' into the search field, it'll come back with a list of suggested queries, such as 'internet', 'international', etc.

• C# Inherited member variables behaving undexpectedly

  - by Nilbert

  If I have a class like this: class A { public string fe = "A"; } And a class that inherits from it like so: class B : A { public string fe = "B"; } Visual C++ will tell me that B.fe hides A.fe so I should use the new keyword. So I change class B to look like: class B : A { public new string fe = "B"; } And then I have a function that takes an A (but, by virtue of inheritance, will also take a B) like this: class D { public static void blah(A anAObject) { Console.Writeline(A.fe); } } Even when I pass it an instance of a B object, which it will take without question, it will print "A"! Why is this, and how can I make it work how I want without setting the variable in the constructor?
