I have this XML document <AdditionalParameters> <PublishToPdf Type ="System.Boolean">False</PublishToPdf> </AdditionalParameters> in my code and I'm trying to build an array of arguments containing the <PublishToPdf> node. object test = (object) ((typeof(publishNode.Attributes["Type"].value)) publishNode.InnerText); This breaks at ...
Hello, I've built this model which contains a generic foreign key: class MyModel(models.Model): content_type = models.ForeignKey(ContentType, verbose_name=_('content type')) object_id = models.PositiveIntegerField(_('object id')) content_object = generic.GenericForeignKey('content_type', 'object_id') Next I've made a gene...
I modified the extension method Thorarin gave in response to this question to work on an int instead of a string: public static TEnum ToEnum<TEnum>(this int intEnumValue, TEnum defaultValue) { if (!Enum.IsDefined(typeof(TEnum), intEnumValue)) return defaultValue; return (TEnum)intEnumValue; } The compiler gives the err...
I have a List that is guaranteed to contain just one type object. This is created by some underlying code in a library that I cannot update. I want to create a List<ObjectType> based on the incoming List object so that my calling code is talking to List<ObjectType>. What's the best way to convert the List (or any other object collect...

Hi How can I call a generic method (.NET 3.5 SP1) from IronRuby v0.9? Trying to do something as obj.method(:method_name).of(String).call seems not to work as "of" is an unknown method. Thanks a lot ...
Is there a way to point to the last item added to a generic list in c# ? Like the back() for a vector in c++ ...
I want to do something like this (from my urls.py), but I don't know if it's possible to get the user making the request: url(r'^jobs/(page(?P<page>[0-9]+)/)?$', object_list, {'queryset': Job.objects.filter(user=request.user), 'template_name': 'shootmpi/molecule_list.html'}, name='user_jobs'), ...
I am trying to implement a generic sort utility method for a List of objects of any class that implements MyInterface. Per Java API (http://java.sun.com/javase/6/docs/api/java/util/Collections.html), Collections.sort() method signature is: public static <T> void sort(List<T> list, Comparator<? super T> c) I am not sure if List with a ...
I have a custom class called "Parameter" and a custom activity with generic collection property called "Parameters", and I want to set bindings for one of Parameters in the generic list of Parameters Property,I've tried with activitybind, but it is not working, is there any way to do it with workflow foundation? please see codes below: ...
Hi all, I am looking to implement an interface which has a function which will return the type of the base class without using a generic interface. Is this possible? class MyClass : MyInterface<MyClass> // Would rather use one below class MyClass : MyInterface // Functions already know to use MyClass ...
I don't understand why in some cases I can make an explicit cast and in other cases I can not. Thanks to all! //DAreaLabel extends Message //This Code Works List<Message> list1 = (List<Message>) Arrays.asList((Message[]) getPageRecords(getClasspath(), methodName, object)); DAreaLabel areaLabel = (DAreaLabel) ((List<M...
Yet again I find myself struggling with the C++ syntax. I'm trying to iterate over a list of generic objects. That is I have objects of a class Event<Q>, crammed into a std::list<Event<Q> >. So I'm trying to get an iterator over the list and intuitively thought that std::list<Event<Q> >::iterator it; for (it = events.begin(); it != ev...
I have a requirement whereby I needed to store a simple cache of a list of items. I was using List< T > for this purpose, but we have now changed the design to accomodate multiple threads. The architecture of the system is driven by events, therefore it's quite likely that a read and write operation could collide. Since the vast majorit...
The problem I am trying to make a generic http module in asp.net C# for handling roles defined by an enum which i want to be able to change by a generic parameter. This will make it possible to use the generic module with any kind of enum defined for each project. The module hooks into the Authenticate event of the FormsAuthenticationM...
I'm using a Dictionary<> to store a bazillion items. Is it safe to assume that as long as the server's memory has enough space to accommodate these bazillion items that I'll get near O(1) retrieval of items from it? What should I know about using a generic Dictionary as huge cache when performance is important? EDIT: I shouldn't rely on...
I'm trying to detect if a particular instance of a Type object is a generic "IEnumerable"... The best I can come up with is: // theType might be typeof(IEnumerable<string>) for example... or it might not bool isGenericEnumerable = theType.GetGenericTypeDefinition() == typeof(IEnumerable<object>).GetGenericTypeDefinition() if(isGenericE...
Note, this question is a bit subtle so read it carefully: I'm not just trying to find out whether some artibitrary type implements IEnumerable: Here's a function I've written with an initial implementation: // is "toType" some sort of sequence that would be satisfied // by an array of type T? If so, what is the type of T? /...

I would like to take requests for /somefolder/style.css and handle them with /somefolder/program.php So, I put the following in my .htaccess file: rewriteengine on rewriterule ^style.css$ program.php?css=1 [R=302,L] The result is that instead of redirecting to /somefolder/program.php, the server tries to redirect to: /var/www/html...
