This talk will give a brief vision of the future and then an introduction to the science base that is forming to support these new directions in computer science. SOFTWARE ENGINEERING - Fueling the Future: FAPESP Wednesday, Sep 18, 2013 ARTICLE: Joint research centers offer a location where dedicated researchers can collaborate openly and are free to make an impact with other researchers

HTML Editor Smart Tasks In Design view, complex properties of server controls often have associated dialog boxes and wizards to make it easy to set them. For ASP.NET Web Forms controls, Smart Tasks appear on server tags as a small glyph when the insertion point is inside the element: The Smart Task expands when you click the glyph or press CTRL+

(Bonus read: Apache Cordova vs Adobe PhoneGap: the differences and which one to use) Pre-requisites In order to install either PhoneGap or Cordova you need to first install Node.js. Like in any other language that supports them, namespaces provide a way to logically group functionality into units, but also help you avoid name collisions (because you cannot have two symbols with the same name in the same namespace, but you can have in two different namespaces)

Advanced filters and multi column sorting Making the NextPage and PrevPage Functions more generic to accept the function name to be called and then calling that function only(if any of you implement this plz share here), i will do all these but it may take some time for me as i m very busy with my schedule. @amiTThanks buddy but i think my previous view count is already gone,so please tell me if this is again gonna happen or not.Anyways thanks for the script April 5, 2009 at 3:35 AM RRave said..

That way, the user can authenticate to the client web app and the app pool identity can then delegate that Kerberos ticket back to SharePoint when calling the search service.

I have not used this yet in production, however it seems that MySQL and Entity Framework 4 is now a viable solution for those not married to SQL Server. This works fine, however fetch strategies are likely needed to be reused in different places so having the .Include with magic strings everywhere becomes a real maintenance headache

The actual classes that represent records in the database are generated magically at runtime (hurray for scripting languages) and the files that define the classes only really contain information about relationships between different tables and other code that cant be generated on the fly by accepting the default implementation for everything. This flexible design is really convenient, but comes at the cost of not having straightforward SQL access (sorting, and filtering) to the contents of the field

On the other hand, div elements can be useful for stylistic purposes or to wrap multiple paragraphs within a section that are all to be annotated in a similar way. Similarly, if the user agent initially estimated the media resource's duration instead of determining it precisely, and later revises the estimate based on new information, then the duration would change and the durationchange event would be fired

As you might expect, a database is used as the repository for the data, and (given the correct permissions) this data is available to any number of apps. Such methods belong to that class and need have no connection with any code outside the class (indeed, proper object oriented design often precludes outside connections)

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

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)

  http://stackoverflow.com/questions/341264/linq-max-or-default
I needed a solution to work in unit tests using Linq-objects (in Linq-objects Max() works with nulls) and Linq-sql when executing in a live environment. Division by zero, taking the max of the empty set, wiggering the spacklerorke, and riding the flying unicorn to Neverland are all meaningless, impossible, undefined

The application provides the following functionality: Return Full Tables Return Typed Lists Return Single Typed Values Insert Data Update Data Delete Data Execute Stored Procedures Select Filtered Lists Select Ordered Lists Perform Aggregate Functions There is a great deal more that one can do with LINQ to SQL that is not contained in this demonstration; however, the demonstration was geared towards the mechanics of performing the most typical types of queries that might be required within a data driven application. Code: Main Application Form (frmMain.cs) This is the main form of the application; this form is used to provide a test harness for testing each of the functions defined in the Accessor class

Extensible Markup Language (XML) 1.0 (Fifth Edition)


  http://www.w3.org/TR/REC-xml/
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

What I want to do is replace the Gurhan button en masse to the standard VB button.What I have done is written a simple VB program that reads in the .frm files of the project as text, and made the appropriate replacements. Web Forms :: BoundField In Gridview Automatically Converts To Textboxes forums.asp.net When using a simple gridview targeting .net 4.0 if i click the edit button twice it converts to BoundFields to textboxes, but in previous version of .net (3.5 and 2.0) nothing happens (eventhough msdn says it suppose to happen)

Is there a way for LINQ to handle this without doing multiple trips to the database? Richard M Mathis - Wednesday, April 25, 2007 9:02:55 PM Hi Scott, me agsin. Using Query Syntax Projections with a Database This projection feature ends up being incredibly useful when working with data pulled from a remote data provider like a database, since it provides us with an elegant way to indicate which columns of data our ORM should actually fetch from a database

Depending on your budget splashing out an a decent SAN solution may help - although SAN technology is beyond my current level of experience, I am just someone who uses it while other people configure it. I think many people still forget that computers have moving parts, they are machines - they are not some sort of quantum flux probability engine that returns results at the speed of light

Catch the Dot - Generic Delegate Types : Func,Action and Predicate


  http://weblogs.asp.net/pawanmishra/generic-delegate-types-func-action-and-predicate
Of all these changes , some are altogether new functionalities in language , some enhance previous features by adding additional capabilities or by just simplifying the syntactical structure. It is very much likely that I might have missed some possibilities while listing the above items.But all in all when you are working with collection and you know what kind of output you want , you are then pretty much sure what delegate type to use

Rich Query for DataSet- An Introduction to LINQ to DataSet


  http://www.codemag.com/article/0712052
First, even though the individual rows in the query result are live (the individual elements in the sequence are the same DataRows as those from the original source DataTable(s)) the results of the query are not live. Hence, it becomes desirable in some cases to take the results on a LINQ to DataSet query and turn it into a DataView or load it into a DataTable.The AsLinqDataView query operator takes a LINQ to DataSet query and turns it into a DataView instance
