  • HTTP redirect fallback

    - by Ondrej Stastny
    Hi, Is there a way to provide fallback URL when HTTP redirect times out? What I'm trying to achieve is that when I hit the original url, I would respond with HTTP redirect (300, 307?) giving the browser new URL and the fallback URL in case the new URL times out? I was also considering doing this client side but it just does not seem to be very effective (in terms of speed, client support). What I would do is probably have a tiny 1x1px image on each server, try loading it and then check with javascript which server is up and redirect there. Any other ideas? Thanks

  • Why in landscape orientation in simulator all the subviews appear out of order?

    - by wolverine
    I was doing a sample app in ipad. I added about 4 to 5 imageviews to the left side of the view vertically. This view will appear when we select the corresponding entry in the splitviewcontroller. In ipad simulator too, all the images were loading and all are working fine in portrait orientation. But when I rotate the simulator to landscape orientation, these imageviews doesnt appear where i placed them. Some of them overlapping each other, some have half of their part in the navigation bar and all. Has gone completely out of order. I am confused why is all this happening. Can anyone help me solve this issue?

  • Empty list in appengine datastore: java vs python

    - by lOranger
    I have the following java model class in AppEngine: public class Xyz ... { @Persistent private Set<Long> uvw; } When saving an object Xyz with an empty set uvw in Java, I get a "null" field (as listed in the appengine datastore viewer). When I try to load the same object in python (through remote_api), as defined by the following python model class: class Xys(db.Model): uvw = db.ListProperty(int) I get a "BadValueError: Property uvw is required". When saving another object of the same class in python with an empty uvw list, the datastore viewer print a "missing" field. Apparently empty lists storage handling differs between Java and python and lead to "incompatible" objects. Thus my question: Is there a way to, either: force Java to store an empty list as a "missing" field, force Python to gracefully accept a "null" list as an empty list when loading the object? Or any other suggestion on how to handle empty list field in both languages. Thanks for your answers!

  • MVC nhibernate entiry mapping for dropdown list

    - by Rod McLeay
    Hi, I have a dropdown list on an ASP.NET MVC project that I am pretty sure is not binding to my model because of my nhibernate mapping. I have tried many variations on the asp mvc side resulting in this post here. MVC side of things seems fine I believe the issue may be that my object is trying to bind, but my mapping is out of whack. My mapping is: <many-to-one name="Project" lazy="false" class="AgileThought.ERP.Domain.Property.Project" column="ProjectGUID" /> My View gives an error saying that the GUID from the dropdownList selected value is not valid. Which I think may be that it is trying to push the GUID into my related project object. The value 'fd38c877-706f-431d-b624-1269184eeeb5' is invalid. My related project list binds to the dropdown list just fine, it is just not binding to my models Project entity. Does the related Project entity need to know about its relationship? Its really just a lookup list. Many thanks for your time and best regards, Rod

  • Choosing random action, Flash AS3

    - by esryl
    I have 2 actions in a Flash file that I would like to test for conversion. One is opening a link in a tab/window, the other loading the content in a Colorbox iframe over the page. How do I randomly choose one of the following actions? I currently listen for a click on a button: clickJoin.addEventListener(MouseEvent.CLICK,toJoin); My two actions are: navigateToURL(new URLRequest("http://www.google.com/"), '_blank'); and ExternalInterface.call('$.fn.colorbox({ href: "http://www.google.com/", width:"80%", height:"80%", iframe:true, onLoad:function(){ $("#player").css({"visibility":"hidden"}); }, onClosed:function(){ $("#player").css({"visibility":"visible"}); }}) ');

    - by Rita
    Hi I have an ASP.NET MVC page(Registration). On loading the page, i am calling Jquery Dialog with Agree and Disagree buttons on that Dialog. 1). How to set the focus to Agree button by default? 2). How to disable the X (Close) Mark that is on Top right corner? (So that i don't want the user to close that dialog simply).

  • IE7 Animated GIF Appears as a Static Image?

    - by Abs
    Hello all, After a button is clicked to start a process on my web app, I show a small loading gif (animated) that rotates to indicate to the user something is happening. I put the gif img in place of the button like this using JQuery: $('#btn_holder').html('<img src="images/loading2.gif" style="margin-left:40px; margin-top:7px;" />'); This works great in all browsers (Firefox, IE8, Chrome) except IE7 on a windows server 2003. In IE, the gif appears but it is not animated. What's going on with IE7? How can I test what the problem is? Thanks all

  • Preload a lot of tiny pics

    - by clorz
    I'm thinking about how to approach the problem at hand. There's a flash movie that requires a lot of relativly small images and I'm trying to optimize the time it takes for them to be preloaded. One thing I've considered it turning on KeepAlive in Apache on the server side. That works. But my mind still wonders if there's anything else ;-) So, what other approaches I may try? Is there a way to compress all those images and then unpack on client side? I have full control on both server and client side. Can even try installing something other than Apache. Cache is not an option because it already works and it's first time loading that bothers me here.

  • Java File and ByteArray or InputStream - please quick help

    - by Peter Perhác
    I want to use jFuge to play some MIDI music in an applet. There's a class for the MIDI pattern - Pattern - and the only method to load the pattern is from a File. Now, I don't know how applets load files and what not, but I am using a framework (PulpCore) that makes loading assets a simple task. If I need to grab an asset from a ZIP catalogue, I can use the Assets class which provides get() and getAsStream() methods. get() returns the given asset as a ByteArray, the other as an InputStream. I need jFuge to load the pattern from either ByteArray or InputStream. In pseudo-code, I would like to do this: Pattern.load(new File(Assets.get("mymidifile.midi"))); however there is no File constructor that would take a ByteArray. Suggestions, please?

  • fb:request-form in iframe redirects away from facebook

    - by IkimashoZ
    I have an <fb:requestform> in an iFrame Facebook app. I have set target="_parent", so that the callback will target the parent iFrame and not itself, which seems to work as expected. But, instead of my desired file loading, I get redirected to my server. Checking the response of the requestform's POST in Firebug revealed this: <script type="text/javascript"> top.location.href = "http://www.facebook.com/login.php?api_key=***&v=1.0&req_perms=&next=http%3A%2F%2F***"; </script> I have already had this same problem when sending jQuery AJAX requests to update various elements in an iFrame. I solved the problem by making sure my headers contain P3P: CP="CAO PSA OUR". That is indeed set for this call as well (can be seen clearly in Firebug), but I still get redirected to facebook.com/login.php.

  • Django syncdb not making tables for my app

    - by Rosarch
    It used to work, and now it doesn't. python manage.py syncdb no longer makes tables for my app. From settings.py: INSTALLED_APPS = ( 'django.contrib.auth', 'django.contrib.contenttypes', 'django.contrib.sessions', 'django.contrib.sites', 'mysite.myapp', 'django.contrib.admin', ) What could I be doing wrong? The break appeared to coincide with editing this model in models.py, but that could be total coincidence. I commented out the lines I changed, and it still doesn't work. class MyUser(models.Model): user = models.ForeignKey(User, unique=True) takingReqSets = models.ManyToManyField(RequirementSet, blank=True) takingTerms = models.ManyToManyField(Term, blank=True) takingCourses = models.ManyToManyField(Course, through=TakingCourse, blank=True) school = models.ForeignKey(School) # minCreditsPerTerm = models.IntegerField(blank=True) # maxCreditsPerTerm = models.IntegerField(blank=True) # optimalCreditsPerTerm = models.IntegerField(blank=True) UPDATE: When I run python manage.py loadddata initial_data, it gives an error: DeserializationError: Invalid model identifier: myapp.SomeModel Loading this data had worked fine before. This error is thrown on the very first data object in the data file.

  • SQLAlchemy DetachedInstanceError with regular attribute (not a relation)

    - by haridsv
    I just started using SQLAlchemy and get a DetachedInstanceError and can't find much information on this anywhere. I am using the instance outside a session, so it is natural that SQLAlchemy is unable to load any relations if they are not already loaded, however, the attribute I am accessing is not a relation, in fact this object has no relations at all. I found solutions such as eager loading, but I can't apply to this because this is not a relation. I even tried "touching" this attribute before closing the session, but it still doesn't prevent the exception. What could be causing this exception for a non-relational property even after it has been successfully accessed once before? Any help in debugging this issue is appreciated. I will meanwhile try to get a reproducible stand-alone scenario and update here. Update: This is the actual exception message with a few stacks: File "/home/hari/bin/lib/python2.6/site-packages/SQLAlchemy-0.6.1-py2.6.egg/sqlalchemy/orm/attributes.py", line 159, in __get__ return self.impl.get(instance_state(instance), instance_dict(instance)) File "/home/hari/bin/lib/python2.6/site-packages/SQLAlchemy-0.6.1-py2.6.egg/sqlalchemy/orm/attributes.py", line 377, in get value = callable_(passive=passive) File "/home/hari/bin/lib/python2.6/site-packages/SQLAlchemy-0.6.1-py2.6.egg/sqlalchemy/orm/state.py", line 280, in __call__ self.manager.deferred_scalar_loader(self, toload) File "/home/hari/bin/lib/python2.6/site-packages/SQLAlchemy-0.6.1-py2.6.egg/sqlalchemy/orm/mapper.py", line 2323, in _load_scalar_attributes (state_str(state))) DetachedInstanceError: Instance <ReportingJob at 0xa41cd8c> is not bound to a Session; attribute refresh operation cannot proceed The partial model looks like this: metadata = MetaData() ModelBase = declarative_base(metadata=metadata) class ReportingJob(ModelBase): __tablename__ = 'reporting_job' job_id = Column(BigInteger, Sequence('job_id_sequence'), primary_key=True) client_id = Column(BigInteger, nullable=True) And the field client_id is what is causing this exception with a usage like the below: Query: jobs = session \ .query(ReportingJob) \ .filter(ReportingJob.job_id == job_id) \ .all() if jobs: # FIXME(Hari): Workaround for the attribute getting lazy-loaded. jobs[0].client_id return jobs[0] This is what triggers the exception later out of the session scope: msg = msg + ", client_id: %s" % job.client_id

  • PostGIS - can't create spatially-enabled database

    - by itgorilla
    I'm using Ubuntu 10.10, PostgreSQL 9.0 and PostGIS 1.5. I've installed PostGIS 1.5 from: https://launchpad.net/~ubuntugis/+archive/ubuntugis-unstable I used PPA first then the command: sudo apt-get install postgis to install postgis. I've been following these instructions to create a spatially-enabled database: http://ostgis.refractions.net/docs/ch02.html#id2630100 I got to the point where it's saying: Now load the PostGIS object and function definitions into your database by loading the postgis.sql definitions file (located in [prefix]/share/contrib as specified during the configuration step). psql -d [yourdatabase] -f postgis.sql Well, there is no postgis.sql on my server after the installation. I did an sudo updatedb to make sure I can find postgis.sql but it's not there. Any ideas? Thank you!

  • how to remove dynamically loaded images in javascript

    I'm loading in 3 images (named 1.jpg, 2.jpg, 3jpg) dynamically to 3 divs called "div1", "div2" and "div3". function loadImages() { for (var i = 1; i < 3; i++ ) { var img = document.createElement("img"); img.src = "vegetables/"+i+".jpg"; img.id = "a"+i+""; var divName = "div"+i+""; document.getElementById(divName).appendChild(img); } } That works, but the removing part I can't seem to get to work.. function removeImages() { for (var i = 1; i < 3; i++ ) { var oldImages = "a"+i+""; var divName = "div"+i+""; document.getElementById(divName).removeChild(oldImages); } } Thank you.

  • iPhone – How to import/drawing UI graphic elements? CGContextDrawPDFPage?

    Hello, What is the best way to use the custom UI graphics on the iPhone? I've come across CGContextDrawPDFPage and Panic's Shrinkit. Should I be using storing my vector ui graphics as PDF's and loading them using CGContextDrawPDFPage to draw them. I did previously asked what way Apple store their UI graphics and was answered crushed png. The options as I see it, but I would really want to know what technique other people use. This question is for vector graphics only. Looking for what is standard / most effective / most efficient. PNG (bitmapped image) Custom UIView drawing code (generated from Opacity) PDF (I've not used this method, is it with CGContextDrawPDFPage?) Many thanks Ross

  • MySQL-python 1.2.3 and OS X 10.5: 64- or 32-bit?

    - by Dave Everitt
    I've been happily using Django and MySQL in development on an existing machine running OS X 10.4 Tiger, and have set up a similar environment in 10.5 Leopard on a new 64-bit MacBook, with a working MySQL and Python 2.6.4. However, now I want them to communicate, easy_install MySQL-python gave ld warnings that the file is not of the required architecture, which led me to test my Python 2.4.6 install (from the Mac OS X disc image): >>> import sys >>> sys.maxint 2147483647 Ah. So my Python install appears to be 32-bit and (I think?) won't install MySQL-python for my 64-bit MySQL. There are lots of hacks out there for MySQL-python on OS X (mostly 1.2.2), but - after hours of reading - I'm pretty sure they won't fix this architecture mismatch. So I'm stuck because I can't decide whether to: give up, remove the 64-bit MySQL install (thorough methods, please?) and use the 32-bit MySQL disc image instead; re-install Python in 64-bit mode from the tarball, --with-universal archs-64-bit and --enable-universalsdk= as detailed in Python.org's 2.6 news. So my questions for anyone who has encountered this issue are: Is installing 64-bit Python on OS X 10.5 worth bothering with? If so, (naive, lazy question!) how are the two required arguments combined? If I just skip along in 32-bit (as on my working setup) what am I missing? I'm after a hassle-free install that's easy to reproduce on other machines (possible student use) so I'd really welcome your opinions, please!

  • MVVM- How would I go about propagating settings between my main view-model (and other view-models) a

    - by Justin
    I am building a settings dialog for my application and right now all of the settings correspond with settings on the main view-model, but as I add more view's and view-models some may not. I need to know what the best practice is for loading the current settings into the settings dialog and then saving the settings to thier corresponding view-models if the user clicks okay. I will not be using the Properties.Settings.Default system to store settings since I want my application to be as portable as possible and this would store user scoped settings in the directory: C:\Users\ username \Local Settings\Application Data\ ApplicationName Instead of in my application's directory. In case it makes any difference I am using the MVVM Light Toolkit by Laurent Bugnion.

  • Dojo load time extremely slow on iis

    - by Josh
    I am currently working on a project that is using Dojo as the js framework. Its a rather rich ui and as such is using (and thus loading) a lot of different .js files for the dojo plug-ins When run on an apache server running on a mac, the files (all around 1k) are served very quickly (1 or 2 ms) and the page loads pretty fast (<5 seconds) When run on IIS on Win 7, the files are served at an unbelievably slow rate (150ms - 1s), thus causing the page to take up to 3 minutes to load. I have searched the internet to try to find a solution and have come up empty. Anyone have any ideas?

  • using indexer to retrieve Linq to SQL object from datastore

    - by fearofawhackplanet
    class UserDatastore : IUserDatastore { ... public IUser this[Guid userId] { get { User user = (from u in _dataContext.Users where u.Id == userId select u).FirstOrDefault(); return user; } } ... } One of the developers in our team is arguing that an indexer in the above situation is not appropriate and that a GetUser(Guid id) method should be prefered. The arguments being that: 1) We aren't indexing into an in-memory collection, the indexer is basically performing a hidden SQL query 2) Using a Guid in an indexer is bad (FxCop flagged this also) 3) Returning null from an indexer isn't normal behaviour 4) An API user generally wouldn't expect any of this behaviour I agree to an extent with (most of) these points. But I'm also inclined to argue that one of the characteristics of Linq is to abstract the database access to make it appear that you're simply working with a bunch of collections, even though the lazy evaluation paradigm means those collections aren't evaluated until you run a query over them. It doesn't seem inconsistent to me to access the datastore in the same manner as if it was a concrete in-memory collection here. Also bearing in mind this is an inherited codebase which uses this pattern extensively and consistently, is it worth the refactoring? I accept that it might have been better to use a Get method from the start, but I'm not yet convinced that it's completely incorrect to be using an indexer. I'd be interested to hear all opinions, thanks.

  • Read assembly Guid without locking the DLL in an appdomain in medium trust ASP.Net

    Is it possible to read the GUID from the Assembly without actually loading it in the current App Domain. Normally Assembly.Load loads the DLL into the app domain. I just want to read the value.
