• compiling numpy with sunperf atlas libraries

  - by user288558

  I would like to use the sunperf libraries when compiling scipy and numpy. I tried using setupscons.py which seems to check from SUNPERF libraries, but it didnt recognize where mine are: here is a listing of /pkg/linux/SS12/sunstudio12.1 (thats where the sunperf library lives): wkerzend@mosura:/home/wkerzend>ls /pkg/linux/SS12/sunstudio12.1/lib/ CCios/ libdbx_agent.so@ libsunperf.so.3@ amd64/ libfcollector.so@ libtha.so@ collector.jar@ libfsu.so@ libtha.so.1@ dbxrc@ libfsu.so.1@ locale/ debugging.so@ libfui.so@ make.rules@ er.rc@ libfui.so.1@ rw7/ libblacs_openmpi.so@ librtc.so@ sse2/ libblacs_openmpi.so.1@ libscalapack.so@ stlport4/ libcollectorAPI.so@ libscalapack.so.1@ svr4.make.rules@ libcollectorAPI.so.1@ libsunperf.so@ tools_svc_mgr@ I tried to specify this directory in sites.cfg, but I still get the following errors: Checking if g77 needs dummy main - MAIN__.

• Which collection interface should I use in .NET for COM-interop?

  - by jhominal

  That is a followup from my previous question, but you don't need to read it to understand that one. I'm designing an interface in .NET that would be consumed from COM applications (mainly VB6, but Visual C++ 6 is also a possibility) and I would like to use Collection types as argument and return types for the methods in the interface. Questions: What happens to the VB6 built-in collection types (arrays, collections, dictionaries) when they go through interop? My current guess is that: arrays - System.Array collections - Microsoft.VisualBasic.Collection dictionaries - System.Collections.Hashtable Is that correct? Which interfaces should I use as return types? IEnumerable, ICollection, IList, IDictionary? Would I be able to do a For Each in VB6 to iterate over these interfaces? Should I use the generic or non-generic variants of the interfaces?

• Dynamic Linq help, different errors depending on object passed as parameter?

  - by sah302

  I have an entityDao that is inherbited by everyone of my objectDaos. I am using Dynamic Linq and trying to get some generic queries to work. I have the following code in my generic method in my EntityDao : public abstract class EntityDao<ImplementationType> where ImplementationType : Entity { public ImplementationType getOneByValueOfProperty(string getProperty, object getValue){ ImplementationType entity = null; if (getProperty != null && getValue != null) { LCFDataContext lcfdatacontext = new LCFDataContext(); //Generic LINQ Query Here entity = lcfdatacontext.GetTable<ImplementationType>().Where(getProperty + " =@0", getValue).FirstOrDefault(); //.Where(getProperty & "==" & CStr(getValue)) } //lcfdatacontext.SubmitChanges() //lcfdatacontext.Dispose() return entity; } }         Then I do the following method call in a unit test (all my objectDaos inherit entityDao): [Test] public void getOneByValueOfProperty() { Accomplishment result = accomplishmentDao.getOneByValueOfProperty("AccomplishmentType.Name", "Publication"); Assert.IsNotNull(result); } The above passes (AccomplishmentType has a relationship to accomplishment) Accomplishment result = accomplishmentDao.getOneByValueOfProperty("Description", "Can you hear me now?"); Accomplishment result = accomplishmentDao.getOneByValueOfProperty("LocalId", 4); Both of the above work Accomplishment result = accomplishmentDao.getOneByValueOfProperty("Id", New Guid("95457751-97d9-44b5-8f80-59fc2d170a4c"))       Does not work and says the following: Operator '=' incompatible with operand types 'Guid' and 'Guid Why is this happening? Guid's can't be compared? I tried == as well but same error. What's even moreso confusing is that every example of Dynamic Linq I have seen simply usings strings whether using the parameterized where predicate or this one I have commented out: //.Where(getProperty & "==" & CStr(getValue)) With or without the Cstr, many datatypes don't work with this format. I tried setting the getValue to a string instead of an object as well, but then I just get different errors (such as a multiword string would stop comparison after the first word). What am I missing to make this work with GUIDs and/or any data type? Ideally I would like to be able to just pass in a string for getValue (as I have seen for every other dynamic LINQ example) instead of the object and have it work regardless of the data Type of the column.

• Weird generics compile error.

  - by Jouke van der Maas

  I have two classes, a base class and a child class. In the base class i define a generic virtual method: protected virtual Bar Foo<T() where T : Bar {} Then in my child class i try to do this: protected override BarChild Foo() // BarChild inherits Bar { return base.Bar<T as BarChild() } Visual studio gives this weird error: The type 'T' cannot be used as type parameter 'T' in the generic type or method 'Foo()'. There is no boxing conversion or type parameter conversion from 'T' to 'Bar'. Repeating the where clause on the child's override also gives an error: Constraints for override and explicit interface implementation methods are inherited from the base method, so they cannot be specified directly So what am i doing wrong here?

• Passing List (Of ChildClass) as parameter to method expecting List (Of ParentClass)?

  - by Nicholas

  Hi, I have implemented inheritance for two parent classes called Table and Field. Each parent class has several child classes. In the Table parent class, I created a method that expects parameter List(Of Field). I get an error when trying to pass in parameter List(Of ChildField) to the method that expects a parameter of List(Of Field). The error message is as below: Value of type 'System.Collections.Generic.List(Of com.hlb.icisbatch.data.ChildField)' cannot be converted to 'System.Collections.Generic.List(Of com.hlb.icisbatch.data.Field)' My question, is it possible to pass in list of child class as parameter? If it is not a list then it works fine. But somehow it is not possible with lists? Below is sample class structure: Table Field | | ChildTable ChildField I have a method in the parent class: Public Class Table Public Sub New() End Sub Public Overridable Sub setFields(ByVal list As List(Of Field) 'Do work here' End Sub End Class and method in child class: Public Class ChildTable Public Sub New(ByVal list As List(Of ChildField) setFields(ChildField) End Sub End Class

• How to make safe cast using generics in C#?

  - by TN

  I want to implement a generic method on a generic class which would allow to cast safely, see example: public class Foo<T> : IEnumerable<T> { ... public IEnumerable<R> SafeCast<R>() where T : R { return this.Select(item => (R)item); } } However, the compiler tells me that Foo<T>.SafeCast<R>() does not define parameter 'T'. I understand this message that I cannot specify a constraint on T in the method since it is not defined in the method. But how can I specify an inverse constraint?

• Strategy for storing and displaying form dropdown data for provinces, states, prefixes?

  - by meder

  I'm currently migrating from a class that stores lists of countries, states & provinces in the form of arrays to using Zend's Locale data in the form of ldml xml files. These ldml files provide localised lists of countries, currencies, languages - so I'm not exactly sure where I should store US States, ( Canadian Provinces ), Prefixes - I was thinking possibly just create a generic xml file and store it in the same directory as the ldml files, but having doubts because it wouldn't really be localised as I'd store it in English. Should I go with storing it in a generic xml file, or possibly update each of the locale files ( eg en.xml ) and append them? The latter is probably not worth the work, which is why I'm swaying towards just a general.xml or dropdown-data.xml. As for generating dropdown options, I suppose I could just say, grab all US states, append the array with Canadian provinces, and append that with an 'Other' option - does this seem like the right way to go about?

• Giving event control back to xaml/callee to access check/uncheck

  - by dovholuk

  Hi All, I've scoured the Internet but my search-foo must not work if it's out there cause I just can't find the proper search terms to get me the answer I am looking for. So I turn to the experts here as a last resort to point me in the right direction. What I'm trying to do is create a composite control of a text box and a list box but I want to allow the control consumer to decide what to do when say the checkbox is checked/unchecked and I just can't figure it out... Maybe i'm going about it all wrong. What I've done thus far is to: create a custom control that extends ListBox expose a custom DP named "Text" (for the Text box but it's not the important part) craft the generic.xaml so that the list items have a default ItemTemplate/DataTemplate inside the DataTemplate I'm trying to set the "Checked" or "Unchecked" events expose 'wrapper' events as DPs in the custom control that would get 'set' via the template when instatiated As soon as I try something like the following (inside generic.xaml): <DataTemplate> <...> <CheckBox Checked="{TemplateBinding MyCheckedDP}"/> <...> </DataTemplate> I get runtime exceptions, the designer - vs2010 - pukes out a LONG list of errors that are all very similar and nothing I do can make it work. I went so far as to try using the VisualTreeHelper but no magic combination I could find would work nor would it allow me to traverse the tree because when the OnApplyTemplate method fires the listbox items don't exist yet and aren't in the tree. So hopefully this all makes sense but if not please let me know and I'll edit the post for clarifications. Thanks to all for any pointers or thoughts... Like I said maybe I'm heading about it in the wrong way from the start... EDIT (Request for xaml) generic.xaml datatemplate: <DataTemplate > <StackPanel Orientation="Horizontal" > <local:FilterCheckbox x:Name="chk"> <TextBlock Text="{Binding Path=Display}" /> </local:FilterCheckbox> </StackPanel> </DataTemplate> usercontrol.xaml (invocation of custom control) <local:MyControl FancyName="This is the fancy name" ItemChecked="DoThisWhenACheckboxIsChecked" <-- this is where the consumer "ties" to the checkbox events ItemsSource="{Binding Source={StaticResource someDataSource}}" />

• State pattern: Why doesn't the context class implement or inherit the State abstract interface/class

  - by Ricket

  I'm reading about the State pattern. I have only just begun, so of course I begin by reading the entire Wikipedia article on it. I noticed that both of the examples in the article have some base abstract class or Java interface for a generic State's methods/functions. Then there are some states which inherit from the base and implement those methods/functions in different ways. Then there's a Context class which has a private member of type State and which, at any time, can be equal to an instance of one of the implementations. That context class also implements the same methods, and passes them onto the current state instance, and then has an additional method to change the state (or depending on design I understand the change of state could be a reaction to one of the implemented methods). Why doesn't this context class specifically "extend" or "implement" the generic State base class/interface?

• Operation is not valid due to the current state of the object

  - by DBa

  Sometimes, when running a Mono .NET application (it seems to not depend on the input data, as it does not change), I run into following situation: when trying to Dequeue an element from a (non-empty, I check its Count beforehand) Queue, an exception is thrown: Unhandled Exception: System.InvalidOperationException: Operation is not valid due to the current state of the object at System.Collections.Generic.Queue1[DBWorkItem].Peek ()[0x00000] at System.Collections.Generic.Queue1[DBWorkItem].Dequeue () [0x00000] at DBProcessor.process (System.Object q) [0x0006b] in <... Though I can certainly catch this exception, the element is dequeued and lost. Has anyone else encountered this behavior, too?

• Groupby in relationtable

  - by Dofs

  I am creating some tag functionality for a forum using linq2sql, and I have two tables [Tag] TagId TagName [ForumTagRelation] TagId ForumId I would like to retrieve, like SO, the most popular tags. I have tried to do this by: List<Tag> popularTags = db.Tags.Select(x => x.ForumTagRelations.GroupBy(y => y.TagId).OrderByDescending(z => z.Count())).Take(count).ToList(); But this just returns the following error: Error 1 Cannot implicitly convert type 'System.Collections.Generic.List<System.Linq.IOrderedEnumerable<System.Linq.IGrouping<System.Guid?,SampleWebsite.ForumTagRelation>>>' to 'System.Collections.Generic.IEnumerable<SampleWebsite.Tag>'. An explicit conversion exists (are you missing a cast?) The question is how I easily can return a list of tags which has the most counts in the ForumTagRelation table?

• Can't enumerate LinQ results with left join

  - by nvtthang

  var itemSet = from item in da.GetList<Models.account>() join file in objFileStorageList on item.account_id equals file.parent_id into objFile from fileItem in objFile.DefaultIfEmpty() where item.company != null && item.company.company_id == 123 orderby item.updatedDate descending select new { Id = item.account_id, RefNo = item.refNo, StartDate = item.StartDate , EndDate = item.EndDate , Comment = item.comment, FileStorageID = fileItem != null ? fileItem.fileStorage_id : -1, Identification = fileItem != null ? fileItem.identifier : null, fileName = fileItem != null ? fileItem.file_nm : null }; It raises error message when I try to enumerate through collection result from Linq query above. LINQ to Entities does not recognize the method 'System.Collections.Generic.IEnumerable1[SCEFramework.Models.fileStorage] DefaultIfEmpty[fileStorage](System.Collections.Generic.IEnumerable1[SCEFramework.Models.fileStorage])' method, and this method cannot be translated into a store expression foreach (var item in itemSet) { string itemRef= item.RefNo; } Please suggest me any solutions. Thanks in advance.

• setting value to the instance of primitive types

  - by Samreen

  I have a function which performs some operation i.e. fetches some data from database. The generic it takes is primitive type always i.e. int, char, bool, string etc. I can easily create its instance. But I can't set the value that I have fetched from database to this instance. public T PerformOperation<T>() { object instance = (T)Activator.CreateInstance(typeof(T)); object result=FetchData(); instance = (T)result; //It gives error on this statement } The function is called as: int result = PerformOperation<int>(); Is there some way of casting the object Type to any generic type which is always primitive?

• Accessing the Identity object in a MVC repository

  - by Rod

  Hi, I have a pretty generic repository that does basic CRUD for many of my business entities. The entities enherit form a generic object that has a few fields I maintain for all objects. eg. ModifiedBy, CreatedBy, CreatedDate, ModifiedDate. These fields ModifiedBy and CreatedBy will always be set before any update/save. My questions is: Is there any way to gain access to the Identity object from my MVC web application in my repositories? I was hoping to set the modifiedby to the identity user for any update in one shot?? Best Regard, Rod

• IN statement performance in PostgreSQL (and in general)

  - by Vasil

  I know this has probably been asked before, but I can't find it with SO's search. Lets say i've TABLE1 and TABLE2, who should I expect the performance of a query such as this: SELECT * FROM TABLE1 WHERE id IN SUBQUERY_ON_TABLE2; as the number of rows in TABLE1 and TABLE2 grow and id is a primary key on TABLE1. Yes, I know using IN is such a n00b mistake, but TABLE2 has a generic relation (django generic relation) to multiple other tables so I can't think of another way to filter the data. At what (aproximate) ammount of rows in TABLE1 and TABLE2 should I expect to notice performance issues because of this? Will performance degrade linearly, exponentially etc. depending on the number of rows?

• Websphere exception handling

  - by Benjamin

  Hi all, From a security standpoint, what is the best solution to handle application errors with Websphere? I've been thinking of creating a class that is called every time an application error is generated, log the error and display a generic error message to the users. In PHP this can be achieved using the set_exception_handler() function. Is there something similar for websphere that could be configured in the web.xml? I've found codes like this on the internet: <error-page> <error-code>500</error-code> <location>/servlet/ExceptionHandlerServlet</location> </error-page> But that would only work with "500" HTTP error codes. I really want something generic that catches everything. Something like a class that implements a certain interface which can have access to all information about the error. Thanks for your time.

• How to combine 2 or more querysets in a Django view?

  - by Espen Christensen

  Hi, I am trying to build the search for a Django site I am building, and in the search I am searching in 3 different models. And to get pagination on the search result list I would like to use a generic object_list view to display the results. But to do that i have to merge 3 querysets into one. How can i do that? Ive tried this: result_list = [] page_list = Page.objects.filter(Q(title__icontains=cleaned_search_term) | Q(body__icontains=cleaned_search_term)) article_list = Article.objects.filter(Q(title__icontains=cleaned_search_term) | Q(body__icontains=cleaned_search_term) | Q(tags__icontains=cleaned_search_term)) post_list = Post.objects.filter(Q(title__icontains=cleaned_search_term) | Q(body__icontains=cleaned_search_term) | Q(tags__icontains=cleaned_search_term)) for x in page_list: result_list.append(x) for x in article_list: result_list.append(x) for x in post_list: result_list.append(x) return object_list(request, queryset=result_list, template_object_name='result', paginate_by=10, extra_context={'search_term': search_term}, template_name="search/result_list.html") But this doesnt work I get an error when i try to use that list in the generic view. The list is missing the clone attribute. Anybody know how i can merge the three lists, page_list, article_list and post_list?

• 'Why' and 'Where' Generics is actually used?

  - by NLV

  Hi all I know that generics are used to achieve type safety and i frequently read that they are largely used in custom collections. But why actually do we need to have it generic? For example, Why cant i use string[] instead of List<string> Lets consider i declare generic class and it has a property X T x; If i provide a method for the class which does x = x + 1; what does it mean actually? I dono what T is actually going to be and i dono what x = x + 1 going to perform actually? If i'm not able to do my own manipulations in my methods how the generics are going to be help me anyway? I've already studied lot of bookish answers. It would be much appreciated if any one can provide some clear insights in this. Regards NLV

• Java generics: Illegal forward reference

  - by Arian

  Given a generic interface interface Foo<A, B> { } I want to write an implementation that requires A to be a subclass of B. So I want to do class Bar<A, B super A> implements Foo<A, B> { } // --> Syntax error or class Bar<A extends B, B> implements Foo<A, B> { } // --> illegal forward reference But the only solution that seems to work is this: class Bar<B, A extends B> implements Foo<A, B> { } which is kind of ugly, because it reverses the order of the generic parameters. Are there any solutions or workarounds to this problem?
