Extensible Markup Language (XML) 1.0 (Fifth Edition)
All internal parameter entities are well-formed by definition.A consequence of well-formedness in general entities is that the logical and physical structures in an XML document are properly nested; no start-tag, end-tag, empty-element tag, element, comment, processing instruction, character reference, or entity reference can begin in one entity and end in another. By construction, XML documents are conforming SGML documents.XML documents are made up of storage units called entities, which contain either parsed or unparsed data
So if you are going to integrate the AAD Graph service into your application, all you need from your development platform is support for sending http requests and reading JSON response back. The user will be redirected to the Azure AD login page and the user will be redirected back to the Redirect URI we specified in the request parameter after a successful login
SQLCODE -20475 a column mask is already defined for the column column-name in table table-name (existing mask name mask-name) SQLCODE -20476 the function-name function was invoked with an invalid format string format-string. SQLCODE -16088 an expression-type expression has a binding of a namespace prefix prefix-string to namespace uri uri-string, introduced to an element named element-name, that conflicts with an existing namespace binding of the same prefix to a different uri in the in-scope namespaces of that element node
Web IDL (Second Edition)
If the operation used to declare the named property getter did not have an identifier, then the interface definition must be accompanied by a description of how to determine the value of a named property for a given property name. Attributes describe the state that an object implementing the interface will expose, and operations describe the behaviors that can be invoked on the object
This would be useful if you want to automatically generate a Excel out of any other primative data type collection I provided 1 overloads of this method, that accepts a Path as string to save excel file to location on disk. This can come in handy when a webcontrol has a default class (from the ASP.NET markup) and then needs additional classes based on a condition (like whether or not a user is logged in)
Changes are only saved if all participating scopes called SaveChanges Read only mode is available, where data is read using the existing DbContext, but no changes need to be saved. Now the Merge extension method can be used to merge an expression with the initialization of the additional fields for the extended DTO with the existing helper method for the basic fields
Dynamically evaluated SQL LINQ queries - CodeProject
I feel the distinct comparer for result type dynamic is not using the dicationary comparer ( it seems ) resulting in full set of result? I did not look into the detail but still feel the distinct operator not applying on dynamic object. This involves not only a type transformation between TSource and TResult but the calculation of properties on the return type as opposed to only assignment
Using LINQ to Calculate Basic Statistics - CodeProject
As for StdDev - due to using more operators of power and division noone implementation of linq or any parallel method wont be faster than sequential code. The most funny thing - if i run such code in parallel optimization mode (parall dataseries computing) i have 200-300 times general improvement (certainly relative parallel run of not optimized methods)!!! well written sequential code is always better
W3C XML Schema Definition Language (XSD) 1.1 Part 2: Datatypes
Of course, many, perhaps most, references to 1 BCE (or 1 BC) actually refer not to a year in the proleptic Gregorian calendar but to a year in the Julian or "old style" calendar; the two correspond approximately but not exactly to each other. Command-line options, menu choices in a graphical user interface, environment variables, alternative call patterns in an application programming interface, and other mechanisms may all be taken as providing user options
Note that this SQL query form, that causes this problem with its CASE, WHEN, WHEN, ELSE expression, is only generated when we project the results into another object, not when we just project the results straight into the main projection object. Thankfully for those using real SQL Server (I tested on 2008 R2), it seems to be able to deal with this query form and generates an efficient query plan, as shown below
The following example recreates the exact error: So I have a car, which I can take to the mechanic, which sometimes (but not always) is serviced by the mechanic. I still don't really understand why the original error was occuring and this solution does feel a bit hacky, but I've been unable to find any neater way of fixing it
Zeeshan Hirani - Applying aggregates to empty collections causes exception in Linq To SQL
The above query causes exception because there are some employees that do not have any orders and Linq to SQL raises exception complaining that null value cannot be assigned to a member with type System.Decimal which is non-nullable. I was simply trying to force Linq to SQL to generate two different query plans and sure enough modifying the query generates unique SQL queries but they both met the met same fate and caused exception unless you do a correct cast to nullable type
Hence integers should be represented by a reference type like Integer being a real object which is nullable OK: nullability was never thought about when constructing C
I assume its because sum returns an int and not a nullable int, giving sum a int? as input only give the same error, probably cause sum only workes on ints
