• ADO.net, Check if ObjectContext is writeable

  - by user287107

  I have an embedded database in an asp.net mvc project. If I try to write to the file, I sometimes get a write failed exception because the SQL Server can't write to the file. How can I check an ObjectContext, if its writeable, without actually writing something to the database?

• fluent nHibernate mapping of subclassed structure

  - by Codezy

  I have a workflow class that has a collection of phases, each phase has a collection of tasks. You can design a workflow that will be used by many engagements. When used in engagement I want to be able to add properties to each class (workflow, phase, and task). For example a task in the designer does not have people assigned, but a task in an engagement would need extra properties like who is assigned to it. I have tried many different approaches using subclasses or interfaces but I just can't get it to map the way I want. Currently I have the engagement level versions as subclasses, but I can't get Engagement phases to map to engagement workflows. Public Class WorkflowMapping Inherits ClassMap(Of Workflow) Sub New() Id(Function(x As Workflow) x.Id).Column("Workflow_Id").GeneratedBy.Identity() Map(Function(x As Workflow) x.Description) Map(Function(x As Workflow) x.Generation) Map(Function(x As Workflow) x.IsActive) HasMany(Function(x As Workflow) x.Phases).Cascade.All() End Sub End Class Public Class EngagementWorkflowMapping Inherits SubclassMap(Of EngagementWorkflow) Sub New() Map(Function(x As EngagementWorkflow) x.ClientNo) Map(Function(x As EngagementWorkflow) x.EngagementNo) End Sub End Class How would you approach mapping this in fluent (or hbm) so that you could load just the workflow base class when designing the flow, or the engagement subclass versions of each when being used by an engagement?

• Django 1.2 object level permissions - third party solutions?

  - by mawimawi

  Since Django 1.2 final is almost out, I am curious if there are already projects that use the new object level permissions / row level permissions system. [django-authority][1] which is a possible solution for Django up to 1.1 has not been updated for a while, and does not (yet) use the new permissions system. It seems to me that Django-Authority is in a comatose state. Does someone know about upcoming or maybe even finished solutions? I'd appreciate any good links to active projects with at least some downloadable content very much. [1]: http://packages.python.org/django-authority/ django-authority

• jQuery: Get height of hidden element in jQuery 1.4.2

  - by mkoryak

  I need to get height of an element that is within a div that is hidden. Right now I show the div, get the height, and hide the parent div. This seems a bit silly. Is there a better way? I'm using jQuery 1.4.2: $select.show(); optionHeight = $firstOption.height(); //we can only get height if its visible $select.hide();

• In a digital photo, how can I detect if a mountain is obscured by clouds?

  - by Gavin Brock

  The problem I have a collection of digital photos of a mountain in Japan. However the mountain is often obscured by clouds or fog. What techniques can I use to detect that the mountain is visible in the image? I am currently using Perl with the Imager module, but open to alternatives. All the images are taken from the exact same position - these are some samples. My naïve solution I started by taking several horizontal pixel samples of the mountain cone and comparing the brightness values to other samples from the sky. This worked well for differentiating good image 1 and bad image 2. However in the autumn it snowed and the mountain became brighter than the sky, like image 3, and my simple brightness test started to fail. Image 4 is an example of an edge case. I would classify this as a good image since some of the mountain is clearly visible. UPDATE 1 Thank you for the suggestions - I am happy you all vastly over-estimated my competence. Based on the answers, I have started trying the ImageMagick edge-detect transform, which gives me a much simpler image to analyze. convert sample.jpg -edge 1 edge.jpg I assume I should use some kind of masking to get rid of the trees and most of the clouds. Once I have the masked image, what is the best way to compare the similarity to a 'good' image? I guess the "compare" command suited for this job? How do I get a numeric 'similarity' value from this?

• SoundChannel object plays small portion after being stopped and played again

  - by gok

  SoundChannel object is stopped and played again. When played again it plays small portion from the previous position and suddenly jumps back to the beginning. It doesn't play the whole sound before looping. This happens only once, then it loops normally. It happens again if I stop and play. public function play():void { channel = clip.play(trimIn); volume(currentVolume); isPlaying = true; timer.start(); channel.addEventListener(Event.SOUND_COMPLETE, loopMusic); } public function loopMusic(e:Event=null):void { if (channel != null) { timer.stop(); channel.removeEventListener(Event.SOUND_COMPLETE, loopMusic); play(); } } Do I need to somehow reset the soundChannel?

• Clear all class variables between instances

  - by ensnare

  This is probably a stupid question, but what's the best way to clear class variables between instances? I know I could reset each variable individually in the constructor; but is there a way to do this in bulk? Or am I doing something totally wrong that requires a different approach? Thanks for helping ... class User(): def __init__(self): #RESET ALL CLASS VARIABLES def commit(self): #Commit variables to database >>u = User() >>u.name = 'Jason' >>u.email = '[email protected]' >>u.commit() So that each time User is called the variables are fresh. Thanks.

• Wrappers/law of demeter seems to be an anti-pattern...

  - by Robert Fraser

  I've been reading up on this "Law of Demeter" thing, and it (and pure "wrapper" classes in general) seem to generally be anti patterns. Consider an implementation class: class Foo { void doSomething() { /* whatever */ } } Now consider two different implementations of another class: class Bar1 { private static Foo _foo = new Foo(); public static Foo getFoo() { return _foo; } } class Bar2 { private static Foo _foo = new Foo(); public static void doSomething() { _foo.doSomething(); } } And the ways to call said methods: callingMethod() { Bar1.getFoo().doSomething(); // Version 1 Bar2.doSomething(); // Version 2 } At first blush, version 1 seems a bit simpler, and follows the "rule of Demeter", hide Foo's implementation, etc, etc. But this ties any changes in Foo to Bar. For example, if a parameter is added to doSomething, then we have: class Foo { void doSomething(int x) { /* whatever */ } } class Bar1 { private static Foo _foo = new Foo(); public static Foo getFoo() { return _foo; } } class Bar2 { private static Foo _foo = new Foo(); public static void doSomething(int x) { _foo.doSomething(x); } } callingMethod() { Bar1.getFoo().doSomething(5); // Version 1 Bar2.doSomething(5); // Version 2 } In both versions, Foo and callingMethod need to be changed, but in Version 2, Bar also needs to be changed. Can someone explain the advantage of having a wrapper/facade (with the exception of adapters or wrapping an external API or exposing an internal one).

• To see javascript object properties and functions with intellisense in VS.NET

  - by uzay95

  I am creating classes in external files.And adding them with <script src='../js/clsClassName.js' type='text/javascript'></script> tags. When i created an object from this class I can't access its props, and functions with intellisense. Is there any way to achieve this? // clsClassName.js function ClassName(_param1, _param2, _param3) { this.Prop1 = _param1; this.Prop1 = _param2; this.Prop3 = _param3; } ClassName.prototype.f_Add = function(fBefore, fSuccess, fComplete, fError) { } ClassName.prototype.f_Delete = function(fBefore, fSuccess, fComplete, fError) { } Any help would be greatly appreciated...

• Example with Visitor Pattern

  - by devoured elysium

  public class Song { public string Genre { get; protected set; } public string Name { get; protected set; } public string Band { get; protected set; } public Song(string name, string band, string genre) { Name = name; Genre = genre; Band = band; } } public interface IMusicVisistor { void Visit(List<Song> items); } public class MusicLibrary { List<Song> _songs = new List<Song> { ...songs ... }; public void Accept(IMusicVisitor visitor) { visitor.Visit(_songs); } } and now here's one Visitor I made: public class RockMusicVisitor : IMusicVisitor { public List<Song> Songs { get; protected set; } public void Visit(List<Song> items) { Songs = items.Where(x => x.Genre == "Rock").ToList(); } } Why is this any better than just putting a public property Songs and then letting any kind of class do with it anything that it wants to? This example comes from this post.

The class must allocate the memory fore adjacent, but I think it didn't how can I solve this problem?

• Actionscript 3: foreach drawing object in movieclip

  - by Mathias

  Hey, I got a europe map designed in flash (1 movieclip, 1 frame, really simple), which contains the map as drawing objects directly inside the scene and in addition some specific countries as clickable buttons. So far it's working fine. What I need now is to make all the other drawing objects clickable without having to edit and script each object. I'm thinking about something like this (pseudo code): foreach(obj in MovieClip) { if(obj !typeof(Button)) { obj.addEventListener(MouseEvent.MOUSE_DOWN, genericClickListener); } } I just don't know the syntax how to achieve that. Could anybody give me a hint? Thanks, Mathias

• Android Context.bindService always returns false and ServiceConnection object is never triggered

  - by mosfet

  I have followed the Local Service example provided by Google, but my Context::bindService(...) always returns false and there is ServiceConnection::onServiceConnected is also never called. I understand that Context::bindService() returns immediately, but my ServiceConnection object is never triggered. I don't know if these apply My activity is running inside a tabHost and I was wondering if that can affect service binding in any way. The Service itself may have a problem, but I can call start service to the same service with the same Intent and it works as expected. Does anyone have experience with this? Please help me out. Thanks, P.S. I am targeting Android 1.6

• QT: I've inherited from QTreeView. I've inherited from QStandardItem. How do i Style the items?

  - by San Jacinto

  My Google skills must be failing me today. I've inherited from QTreeView to create a TreeView that stores a QStandardItemModel instead of a QAbstractItemModel. I have also inherited from QStandardItem to create a class to store my data in an item as is necessary. I've successfully inserted my derived QStandardItem into my derived QTreeView's QStandardItemModel. Now the trouble is, I can't figure out how to style it. I know that QTreeView has a setStyleSheet(QString) member, but I can't seem to get it working. It may be as simple as I'm not styling the correct attribute. Any pointers would be appreciated. Thanks. For clarity, here are my class defs. class SurveyTreeItem : public QStandardItem { public: SurveyTreeItem(); SurveyTreeItem( const QString & text ); ~SurveyTreeItem(); }; class StandardItemModelTreeView : public QTreeView { public: StandardItemModelTreeView(QWidget* parent = 0); ~StandardItemModelTreeView(); QStandardItemModel* getStandardItemModel(); }; I've tried the following StyleSheets: StandardTreeView::Item { font: 87 12pt 'Arial Black'; } StandardTreeView::QStandardItem { font: 87 12pt 'Arial Black'; } QTreeView::QStandardItem { font: 87 12pt 'Arial Black'; } QTreeView::Item { font: 87 12pt 'Arial Black'; } QTreeView::SurveyTreeItem { font: 87 12pt 'Arial Black'; } StandardTreeView::SurveyTreeItem { font: 87 12pt 'Arial Black'; }

• OOP Design for an Economy

  - by waiwai933

  Not sure where to start, so I'm just going to plow in. Let's say I'm trying to represent an economy in OOP. A basic design I've come up with is: class Person{ int $money; // Money someone has in wallet/purse int $bank_account_id; function getAmountOfMoney() function addMoney($amountToAdd) function subtractMoney($amountToSubtract) } class BankAccount{ int $money; // Money in Bank Account int $interest_per_year; function giveInterest() function depositMoney() // Calls $person->subtractMoney() function withdrawMoney() // Calls $person->addMoney() } Are there any design flaws here?

• WPF TreeView binding to a simple object

  - by esse

  I have a simple object as such: public class Info { public string Name {get; set;} public int Count {get; set;} public DateTime TimeStamp {get; set;} } I want to bind a collection of these objects to a WPF TreeView and have the properties on the Info objects show up as sub TreeViewItems, like so: Item 1 Name: Bill Count: 3 TimeStamp: 12/05/2010 09:06:00 AM Item 2 Name: Chris Count: 22 TimeStamp: 11/05/2010 11:34:00 AM Item 3 Name: Toby Count: 1 TimeStamp: 09/05/2010 05:55:00 PM How can I achieve this through XAML?

• Comments in Activity Stream

  - by fesja

  Hi, I'm starting to develop an activity stream. I've read both How to implement the activity stream in a social network and What’s the best manner of implementing a social activity stream?. What I haven't found is the best way to add comments to the activities. As in facebook, each comment can be commented by another person. If each activity comment is saved as another activity, then I would not be able to get the activity of that comment without doing a query. So the solution I'm thinking is to save the comments inside the serialize data field of each activity. If the user wants to delete his comment, I would have to update that activity. Is this the correct solution? Is there a better approach? Thanks!

• Rendering to a single Bitmap object from multiple threads

  - by Lee Treveil

  What im doing is rendering a number of bitmaps to a single bitmap. There could be hundreds of images and the bitmap being rendered to could be over 1000x1000 pixels. Im hoping to speed up this process by using multiple threads but since the Bitmap object is not thread-safe it cant be rendered to directly concurrently. What im thinking is to split the large bitmap into sections per cpu, render them separately then join them back together at the end. I haven't done this yet incase you guys/girls have any better suggestions. Any ideas? Thanks

• Finding zoom level from window object properties

  - by Mihai Fonoage

  Hi, I want to find out the zoom level of what is being displayed in a browser window based on the javascripts' window object properties (http://www.javascriptkit.com/jsref/window.shtml) to which I have access. I just can't seem to find the right mathematical formula for the zoom based on the inner width, page offset, etc. I found a solution, but that uses the document.body.getBoundingClientRect call which does not return anything in my case and for which I can't tell if there's a suitable replacement from the window properties. I am using Safari. Thank you, Mihai

  I want to know the best solution for this my case here is that i am taking values from Excel sheet and pushing them to database field, sometimes that field might contain some strings (thats why I cant make my object members int / double) In my class below size is the variable responsible for showing size of files in bytes public class dataNameValue { public string Name { get; set; } public string Count { get; set; } public string Size { get; set; } } I wanted to sort the list by file Size something like List mylist = new List(); mylist = mylist.OrderByDescending(i = i.Size).ToList(); The problem is that if i sorted it without converting it to "int/double" first -- its not giving right results
