    Hi everybody, I'm using Linq To Nhibernate, and with a HQL statement I can do something like this: string hql = "from Entity e order by rand()"; Andi t will be ordered so random, and I'd link to know How can I do the same statement with Linq to Nhibernate ?

  • How do I find the "concrete class" of a django model baseclass

    - by Mr Shark
    I'm trying to find the actual class of a django-model object, when using model-inheritance. Some code to describe the problem: class Base(models.model): def basemethod(self): ... class Child_1(Base): pass class Child_2(Base): pass If I create various objects of the two Child classes and the create a queryset containing them all: Child_1().save() Child_2().save() (o1, o2) = Base.objects.all() I want to determine if the object is of type Child_1 or Child_2 in basemethod, I can get to the child object via o1.child_1 and o2.child_2 but that reconquers knowledge about the childclasses in the baseclass. I have come up with the following code: def concrete_instance(self): instance = None for subclass in self._meta.get_all_related_objects(): acc_name = subclass.get_accessor_name() try: instance = self.__getattribute__(acc_name) return instance except Exception, e: pass But it feels brittle and I'm not sure of what happens when if I inherit in more levels.

    - by vix
    I'm using the following code to read the content of a text file using javascript. But when I'm getting an alert message which says "An ActiveX control on this page might be unsafe to interact with other parts of the page. Do you want to allow this interaction?"

  • Why does my app crash when I add an row to the table view?

    - by mystify
    I'm adding a row like this, when a button is pressed. It must be the very first row in the first section: NSIndexPath *indexPath = [NSIndexPath indexPathForRow:0 inSection:0]; [self insertRowsAtIndexPaths:[NSArray arrayWithObject:indexPath] withRowAnimation:UITableViewRowAnimationFade]; I don't call anything else here. No -reloadData. I keep getting this: * Terminating app due to uncaught exception 'NSInternalInconsistencyException', reason: 'Invalid update: invalid number of rows in section 0. The number of rows contained in an existing section after the update (6) must be equal to the number of rows contained in that section before the update (6), plus or minus the number of rows inserted or deleted from that section (1 inserted, 0 deleted).'

  • Outputing resized animated gif to browser using imagick

    - by Freeman
    I intent to resize an animated gif and outputing it to the browser on-the-fly. My problem is that when I save the resized image it is of good quality, but if I echo it to the browser it is of poor quality and the animation is removed. Here is the code:` header("Content-type:image/gif"); try { /* Read in the animated gif */ $animation = new Imagick("images/nikks.gif"); /*** Loop through the frames ***/ foreach ($animation as $frame) { /*** Thumbnail each frame ***/ $frame->thumbnailImage(200, 200); /*** Set virtual canvas size to 100x100 ***/ $frame->setImagePage(200, 200, 0, 0); } /*** Write image to disk.

  • Prevent DTD download when parsing XML, redux

    - by harpo
    I have a folder full of XHTML files, and a console program to process them. The problem is, it doesn't work when I'm offline, because The remote name could not be resolved: 'www.w3.org' A number of sites, including this one, say to set the XmlResolver to null. That is not not working. I have tried setting the XmlResolver to null every way that I can think of: in the XmlDocument, in XmlTextReader, and in the XmlReaderSettings. I believe that it's just creating a default instance. I have also tried implementing my own XmlResolver, but I don't know what to return for external items. public class NonXmlResolver : XmlUrlResolver { public override object GetEntity( Uri absoluteUri, string role, Type ofObjectToReturn ) { if ( absoluteUri.Scheme == "http" ) throw new Exception("What you talking 'bout, Willis?"); else return base.GetEntity( absoluteUri, role, ofObjectToReturn ); } } The documents do not use any special entities, only pure XML. This is possible, right?

  • Tentative date casting in tsql

    - by Tewr
    I am looking for something like TRYCAST in TSQL or an equivalent method / hack. In my case I am extracting some date data from an xml column. The following query throws "Arithmetic overflow error converting expression to data type datetime." if the piece of data found in the xml cannot be converted to datetime (in this specific case, the date is "0001-01-01" in some cases). Is there a way to detect this exception before it occurs? select [CustomerInfo].value('(//*:InceptionDate/text())[1]', 'datetime') FROM Customers An example of what I am trying to achieve in pseudocode with an imagined tsql function TRYCAST(expr, totype, defaultvalue): select TRYCAST( [CustomerInfo].value('(//*:InceptionDate/text())[1]', 'nvarchar(100)'), datetime, null) FROM Customers

  • Isn't fb_sig_friends supposed to be there?

    - by Seeker
    According to the docs, Facebook is supposed to send both fb_sig_canvas_user and fb_sig_friends for a canvas application. Sadly, I only get fb_sig_canvas_user and NOT fb_sig_friends. Is there anything I have to do to get this parameter? Or is there any other way to retrieve the friends of the visiting (not-yet-authorized) user, without the need of a session key (API throws exception with message "Requires user session")? And yes, _fb_fromhash is present in the request (coming to the canvas app. from a user's application tab).

  • C#: proprietary DLLs requiring access to my assemblies

    - by Craig Johnston
    My solution uses a proprietary assembly, which when debugging the solution throws an Exception saying it can't find an assembly that is meant to be one of the projects in my solution. I cannot add a reference to the proprietary assembly because all I have is the DLL. When I compile everything into a single application directory and run the app it works fine, but I want to debug. Where should assemblies be placed if you want a proprietary assembly in the solution to see them? I assume the issue is that there is no path specified and it is just looking in a default directory of some kind.

  • How to invoke a delegate with a null parameter?

    - by Rodney Burton
    I get a null exception if I try to pass a null parameter to a delegate during an invoke. Here's what the code looks like: public void RequestPhoto() { WCF.Service.BeginGetUserPhoto(Contact.UserID, new AsyncCallback(RequestPhotoCB), null); } public void RequestPhotoCB(IAsyncResult result) { var photo = WCF.Service.EndGetUserPhoto(result); UpdatePhoto(photo); } public delegate void UpdatePhotoDelegate(Binary photo); public void UpdatePhoto(Binary photo) { if (InvokeRequired) { var d = new UpdatePhotoDelegate(UpdatePhoto); Invoke(d, new object[] { photo }); } else { var ms = new MemoryStream(photo.ToArray()); var bmp = new Bitmap(ms); pbPhoto.BackgroundImage = bmp; } } The problem is with the line: Invoke(d, new object[] { photo }); If the variable "photo" is null. What is the correct way to pass a null parameter during an invoke? Thanks!

  • Wicket app in embedded Jetty causes UnsupportedClassVersionError

    - by Ondra Žižka
    I've tried to run a Wicket app in an embedded Jetty, using this code: public static void main( String[] args ){ Server server = new Server(8080); Context root = new Context( server, "/", Context.SESSIONS ); FilterHolder filterHolder = new FilterHolder( new WicketFilter() ); filterHolder.getInitParameters().put("applicationClassName", cz.dw.test.WicketApplication.class.getName() ); root.addFilter( filterHolder, "/*" , Handler.ALL ); try { server.start(); } catch (Exception ex) { ex.printStackTrace(); } } But I got java.lang.UnsupportedClassVersionError: Bad version number in .class file. Switching the target class version for my app (1.6 - 1.5) did not help. I use Sun JDK 1.6.0_17, Wicket 1.4.8, Jetty 6.1.24. I tried to debug, but the JRE classes have no debug data. The stacktrace is of no use as it happens when loading the classes into JVM. Any ideas what could be wrong? How can I find which class is causing this? Thanks, Ondra

  • XmlDocument.InnerXml is null, but InnerText is not

    - by Adam Neal
    I'm using XmlDocument and XmlElement to build a simple (but large) XML document that looks something like: <Widgets> <Widget> <Stuff>foo</Stuff> <MoreStuff>bar</MoreStuff>...lots more child nodes </Widget> <Widget>...lots more Widget nodes </Widgets> My problem is that when I'm done building the XML, the XmlDocument.InnerXml is null, but the InnerText still shows all the text of all the child nodes. Has anyone ever seen a problem like this before? What kind of input data would cause these symptoms? I expected the XmlDocument to just throw an exception if it was given bad data. Note: I'm pretty sure this is related to the input data as I can only reproduce it against certain data sets. I also tried escaping the data with SecurityElement.Escape but it made no difference.

  • NHibernate bag is always null

    - by Neville Chinan
    I have set up my mapping file and classes as suggested by many articles class A { ... IList BBag {get;set;} ... } class B { ... A aObject {get;set;} ... } <class name="A">...<bag name="BBag" table="B" inverse="true" lazy="false"><key column="A_ID" /><one-to-many class="B" /></bag>... <class name="B">...<many-to-one name="aObject" class="A" column="A_ID" />... I added a set of A's to the A table and a set of B's to the B table, all the data is stored as expected. However if I try and access aInstance.BBag.Count I get a null reference exception. I think I missing some key knowledge on how an bag gets instantiated. Thanks

  • What adapter to use for ExpandableListView with non-TextView views?

    - by David
    I have an ExpandableListView in which I'd like to have controls other than TextView. Apparently, SimpleExandableListViewAdapter assumes all the controls are TextViews. A cast exception is generated if they are not. What is the recommended solution? Options I can think of include: - Use some other included adapter. But I can't tell if they all have the same assumption. - Create my own adapter. Is there a doc which describes the contract, ie the sequence of method calls an adapter will encounter? I expected the existing adapters to require the views to conform to some interface to allow any conforming view to be used, rather than hardcode to textview and limit where they can be used.

    Hey again Internet ! So i'm trying to write out an object to a ByteArray, but for some reason it's not writting anything, which i see by the fact that the return value is 0, and that by the fact that reading it results in an exception. BAoutput = new ByteArrayOutputStream(); Oout = new ObjectOutputStream(BAoutput); Oout.writeObject(receiver); where receiver is an object i get through a parameter. and the exceptions are always the same: at java.io.ObjectInputStream$BlockDataInputStream.peekByte(Unknown Source) at java.io.ObjectInputStream.readObject0(Unknown Source) at java.io.ObjectInputStream.readObject(Unknown Source) Any ideas?
