  • What permissions are required to create a new work item type in TFS

    - by harsha
    I am new to creating work item types in TFS and want to create a new Work Item type. I looked at work item template option, but that is not sufficient for me. I need to add few new fields and have a customized form. From search I got information about Work Item Type definition but I am looking for some detailed example. Also I would like to know the permissions needed to add a new work item type. I got administrator privileges for my project, but not on TFS as a whole. With that can I add a new template for my project. Please provide me direction.

  • rails: date type and GetDate

    - by cbrulak
    This is a follow up to this question: http://stackoverflow.com/questions/2930256/unique-responses-rails-gem I'm going to create an index based on the user id, url and a date type. I want date type (not datetime type) because I want the day, the 24 hour day to be part of the index to avoid duplication of page views counts on the same day. In other words: A view only counts once in a day by a visitor. I also want the default value of that column (viewdate) to be the function GETDATE(). This is what I have in my migration: execute "ALTER TABLEpage_viewsADD COLUMN viewdate datetime DEFAULTGETDATE()`" But the value viewdate is always empty. What am I missing? (as an aside, any other suggestions for accomplishing this goal?)

  • C# LINQ Where Predicate Type Arguments

    - by blu
    I have an XElement with values for mock data. I have an expression to query the xml: Expression<Func<XElement, bool>> simpleXmlFunction = b => int.Parse(b.Element("FooId").Value) == 12; used in: var simpleXml = xml.Elements("Foo").Where(simpleXmlFunction).First(); The design time error is: The type arguments for method 'System.Linq.Enumerable.Where(System.Collections.Generic.IEnumerable, System.Func)' cannot be inferred from the usage. Try specifying the type arguments explicitly' The delegate supplied to Where should take in an XElement and return a bool, marking if the item matches the query, I am not sure how to add anything more to the delegate or the where clause to mark the type. Also, the parallel method for the real function against the Entity Framework does not have this issue. What is not correct with the LINQ-to-XML version?

  • Displaying UserControls based on the type a TreeView selection is bound to

    - by Ray Wenderlich
    I am making an app in WPF in a style similar to Windows Explorer, with a TreeView on the left and a pane on the right. I want the contents of the right pane to change depending on the type of the selected element in the TreeView. For example, say the top level in the Tree View contains objects of class "A", and if you expand the "A" object you'll see a list of "B" objects as children of the "A" object. If the "A" object is selected, I want the right pane to show a user control for "A", and if "B" is selected I want the right pane to show a user control for "B". I've currently got this working by: setting up the TreeView with one HierarchialDataTemplate per type adding all the UserControls to the right pane, but collapsed implementing SelectedItemChanged on the TreeView, and setting the appropriate usercontrol to visible and the others to collapsed. However, I'm sure there's a better/more elegant way to switch out the views based on the type the selection is bound to, perhaps by making more use of data binding... any ideas?

  • Findbugs warning: Equals method should not assume anything about the type of its argument

    - by Uri
    When running FindBugs on my project, I got a few instances of the error described above. Namely, my overriding versions of equals cast the RHS object into the same type as the object in which the overriding version is defined. However, I'm not sure whether a better design is possible, since AFAIK Java does not allow variance in method parameters, so it is not possible to define any other type for the equals parameter. Am I doing something very wrong, or is FindBugs too eager? A different way to phrase this question is: what is the correct behavior if the object passed to equals is not the same type as an LHS: Is this a false, or should there be an exception? For example: public boolean equals(Object rhs) { MyType rhsMyType = (MyType)rhs; // Should throw exception if(this.field1().equals(rhsMyType.field1())... // Or whatever }

  • Delphi> Please explain this: type... procedure of object

    - by Richard Woolf
    I've encountered some code that's new to me... I've never really seen a type declaration of a procedure of object, and I just don't see the point. Why couldn't the developer simply keep a field of type Boolean? interface type TFinishedCaptureEvent = procedure(AFinished: Boolean) of object; TFrameCard = class(TFrame) ... private FOnFinishedCapture: TFinishedCaptureEvent; public property OnFinishedCapture: TFinishedCaptureEvent read FOnFinishedCapture write FOnFinishedCapture; end; implementation ... if Assigned(FOnFinishedCapture) then FOnFinishedCapture(False);

  • How to add response headers based on Content-type, or getting Content-type before the response is co

    - by Bozho
    I want to set the Expires header for all image/* and text/css. I'm doing this in a Filter. However: before calling chain.doFilter(..) the Content-type is not yet "realized" after calling chain.doFilter(..) the Content-type is set, but so is content-length, which forbids adding new headers (at least in Tomcat implementation) I can use the extensions of the requested resource, but since some of the css files are generated by richfaces by taking them from inside jar-files, the name of the file isn't x.css, but is /xx/yy/zz.xcss/DATB/.... So, is there a way to get the Content-type before the response is committed.

  • How to retrieve a bigint from a database and place it into an Int64 in SSIS

    - by b0fh
    I ran into this problem a couple years back and am hoping there has been a fix and I just don't know about it. I am using an 'Execute SQL Task' in the Control Flow of an SSIS package to retrieve a 'bigint' ID value. The task is supposed to place this in an Int64 SSIS variable but I getting the error: "The type of the value being assigned to variable "User::AuditID" differs from the current variable type. Variables may not change type during execution. Variable types are strict, except for variables of type Object." When I brought this to MS' attention a couple years back they stated that I had to 'work around' this by placing the bigint into an SSIS object variable and then converting the value to Int64 as needed. Does anyone know if this has been fixed or do I still have to 'work around' this mess? edit: Server Stats Product: Microsoft SQL Server Enterprise Edition Operating System: Microsoft Windows NT 5.2 (3790) Platform: NT INTEL X86 Version: 9.00.1399.06

  • Deserialize Stream to List<T> or any other type

    - by Sam
    Attempting to deserialize a stream to List<T> (or any other type) and am failing with the error: The type arguments for method 'Foo.Deserialize<T>(System.IO.Stream)' cannot be inferred from the usage. Try specifying the type arguments explicitly. This fails: public static T Deserialize<T>(this Stream stream) { BinaryFormatter bin = new BinaryFormatter(); return (T)bin.Deserialize(stream); } But this works: public static List<MyClass.MyStruct> Deserialize(this Stream stream) { BinaryFormatter bin = new BinaryFormatter(); return (List<MyClass.MyStruct>)bin.Deserialize(stream); } or: public static object Deserialize(this Stream stream) { BinaryFormatter bin = new BinaryFormatter(); return bin.Deserialize(stream); } Is it possible to do this without casting, e.g. (List<MyStruct>)stream.Deserialize()?

  • Access to an inner type

    - by sohum
    A colleague of mine posted a question on an internal forum which got me thinking about whether this was possible through C#. Basically, he's got an interface as follows: public interface IProvider<T> { T GetT(); } Is it possible to use something that implements that interface as a type parameter to another generic class and have access to the type T without re-specifying it? For example: public class Foo<P> where P : IProvider<T> { P p; T GetInnerT() { return p.GetT(); } } This does not compile, because the type T is not defined and hence can't be used as a parameter for IProvider. Is something like this even possible? Just curious!

  • What is the possible benefit (if any) of allowing recursive contructors?

    - by Penang
    In Java, constructors cannot be recursive. Compile time error: "recursive constructor invocation". Let's assume that we did not have this restriction. Things to keep in mind: The return type of a constructor is void. Since it is a void method you can't harness the complete power of recursion. A constructor can invoke itself (or any other constructor) using this(). But a "call to this must be first statement in constructor" We could use non local data between consecutive calls to still have some possible gain from recursive constructors. Would there be any benefit from allowing recursive constructors?

  • Font-awesome, input type 'submit'

    - by denis.peplin
    It seems no class for input type 'submit' in font-awesome. Is it possible to use some class from font-awesome for button input? I've added icons to all buttons (which actually links with class 'btn' from twitter-bootstrap) in my applications, but can't add icons on 'input type submit'. Or, how to use this code: input#image-button{ background: #ccc url('icon.png') no-repeat top left; padding-left: 16px; height: 16px; } html: <input type="submit" id="image-button">Text</input> (which I took from HTML: How to make a submit button with text + image in it?) with font-awesome?

  • Bound a treeview control to user-defined complex type using EF 4

    - by GIbboK
    Hi, I use Asp.net, SQL 2008 and EF 4. I need display hierarchy data in a treeview control, Data is stored in a DB that use HierarchyId. Unfortunately, EF4 doesn't support HierarchyId. So in this case, I thought to have a stored procedure that deals with my hierarchy and return a result set back to EF that EF4 can turn into a collection of user-defined complex type that can then be bound directly to the treeview control. I imported a SPROC in EF 4 using Import Function and now I have a Complex DataType called: CategoryHierarchy_Result An image of my Model: Here some data from the Complex Type (in a GridView for example GridView1.DataSource = context.CategoryHierarchy(1);): My questions is: How to display my data from my Complex Type in a TreeView Control, showing a Tree structure that respect CategoryNodeString? I am a beginner an I never use TreeView before, any help or resource would be appreciated! Thanks!. Here some useful resource: http://www.robbagby.com/entity-framework/entity-framework-modeling-action-stored-procedures/

  • Activator.CreateInstance with type name as string and including parameters

    - by Kelly
    I am working in .Net 3.5, looking at all the various constructors for Activator.CreateInstance. I want to create an instance of a class, calling a particular constructor. I do not have the class type, only its name. I have the following, which works, but actually winds up calling the parameterless constructor first, then the one I want. This is not a terribly big deal, but the parameterless constructor calls a rather busy base constructor, and the constructor I want to call does, too. In other words, given a type, calling CreateInstance with parameters is easy (only the last two lines below), but given only a type name, is there a better way than this? ObjectHandle oh = Activator.CreateInstance( "MyDllName", "MyNS." + "MyClassName" ); object o = oh.Unwrap( ); object newObj = Activator.CreateInstance( o.GetType( ), new object[] { param1 } ); return ( IMyDesiredObject )newObject; Thanks!

  • Jquery Ajaxform with input type=file and multifile

    - by crunchingnumbers
    Im using ajax form with multifile. However ajaxform just seems to quietly die and does not do anything if using multifile. Multifile is just a jquery plugin that builds a list of input type=file so that you can upload multiple files at once, before which you can add/delete your file upload list. I've looked at multifile and made one change to ensure that it generated a unique name as well as id which it didn't do before and i've checked the form elements multifile is building which all appear to be correct. From looking at ajaxform, it seems that it shoulld just generate the iframe as normal and post the multiple input type=file but it does nothing. Has anyone else experienced problems with multiple input type=file uploads

  • Type Declaration - Pointer Asterisk Position

    - by sahs
    Hello, in C++, the following means "allocate memory for an int pointer": int* number; So, the asterisk is part of the variable type; without it, that would mean something else (that's why I usually don't separate the asterisk from the variable type). Then what is the reason the asterisk is considered something else, instead of being part of the type? For example, it seems better, if the following meant "allocate memory for two int pointers": int* number1, number2; Am I wrong?

  • EntityFramework: Access dabase-column using user defined Type

    - by Nils
    I "inherited" an old Database where dates are stored as Int32 values (times too, but dates shall suffice for this example) i.e. 20090101 for Jan. 1st 2009. I can not change the schema of this database because it is still accessed by the old programs. However I want to write a new program using EF as the O/R-M. Now I'd love to have DateTime-Values in my Model. Is there a way to write a custom type and use this as a Type in the EF-Model. Something like a Type "OldDate" with properties: DatabaseValue : Int23 Value : DateTime (specifying the date-part whereas the time-part is always 0:00:00) Is something like this possible with the EF-Model ?

  • Why is the 'this' keyword not a reference type in C++ [closed]

    - by Dave Tapley
    Possible Duplicates: Why ‘this’ is a pointer and not a reference? SAFE Pointer to a pointer (well reference to a reference) in C# The this keyword in C++ gets a pointer to the object I currently am. My question is why is the type of this a pointer type and not a reference type. Are there any conditions under which the this keyword would be NULL? My immediate thought would be in a static function, but Visual C++ at least is smart enough to spot this and report static member functions do not have 'this' pointers. Is this in the standard?

  • Teaching a kid to type in order to start programming

    - by at
    My 5 year old wants to start programming, but he doesn't yet know how to type without looking for each letter 1 at a time. I know it's going to frustrate him to go so slow because of his typing speed. And it's not going to be fun looking for all the letters constantly... So what's the best way to get him to type fast? Clearly he'll need to type a lot of punctuation like semicolons, colons and symbols. So his little hands will have to get used to spreading over the keyboard... I did some google searches and found some very poor looking apps that focused on the letters.

  • Strange behavior with large Object Types

    - by Peter Lang
    I recognized that calling a method on an Oracle Object Type takes longer when the instance gets bigger. The code below just adds rows to a collection stored in the Object Type and calls the empty dummy-procedure in the loop. Calls are taking longer when more rows are in the collection. When I just remove the call to dummy, performance is much better (the collection still contains the same number of records): Calling dummy: Not calling dummy: 11 0 81 0 158 0 Code to reproduce: Create Type t_tab Is Table Of VARCHAR2(10000); Create Type test_type As Object( tab t_tab, Member Procedure dummy ); Create Type Body test_type As Member Procedure dummy As Begin Null; --# Do nothing End dummy; End; Declare v_test_type test_type := New test_type( New t_tab() ); Procedure run_test As start_time NUMBER := dbms_utility.get_time; Begin For i In 1 .. 200 Loop v_test_Type.tab.Extend; v_test_Type.tab(v_test_Type.tab.Last) := Lpad(' ', 10000); v_test_Type.dummy(); --# Removed this line in second test End Loop; dbms_output.put_line( dbms_utility.get_time - start_time ); End run_test; Begin run_test; run_test; run_test; End; I tried with both 10g and 11g. Can anyone explain/reproduce this behavior?

  • How can I use multiple PHP header content types on the same page? is this possible?

    - by Jon
    Is it possible to use multiple header types in one document? For example: header("Content-type: image/jpeg"); header('Content-Type: text/html; charset=utf-8'); returns the whole page as text/html... while header('Content-Type: text/html; charset=utf-8'); header("Content-type: image/jpeg"); Returns the whole page as an image.... How can I use both types of content on the same page? I'm using ob_start() at the top and ob_end_flush() at the beginning.
