Innovations In Data Access:SQL Server “Yukon”

• Extend SQL’s type system, stored procs, functions, triggers in managed code

• Leverage broad developer ecosystem

• Wide choice of languages – Visual Basic, C#, MC++,

COBOL, …and T-SQL

• Leverages much of the .NET Framework – BCL, network access,

Web services…

• Enable third parties to write libraries to extend the DB

Enhancing The Base LibraryGeneric Collections

• System.Collections.Generic classes– List<ItemType>– Dictionary<K,V>– Stack<ItemType>– Queue<ItemType>

• System.Collections.Generic interfaces– IList<ItemType>– IDictionary<K,V>– ICollection<ItemType>– IEnumerable<ItemType>– IEnumerator<ItemType>– IComparable<OperandType>– IComparer<OperandType>

Enhancing The Base LibraryOther Generics to look out for

• Nullable<T>– Extremely useful for situations where null is a value, such as

database valuetypesNullable<int> intVal = Nullable<int>.default;intVal = 5; // implicit cast from int int i = (int)intVal; // explicit cast to int if (intVal.HasValue) { // checks for a value

• EventHandler<T>– Saves on making your own EventHandlers

delegate void EventHandler<T>(Object sender, T e) where T : EventArgs;

Enhancing The Base LibraryOther Generics to look out for

• IComparable<T>– No boxing of valuetypes on comparison/sorting– No chance of passing in an invalid type

public class DemoString : IComparable<string> { public int CompareTo(string other) ; public bool Equals(string other);}

• ArraySegment<T>– Allows you to easily specify a subsection of an array– Supports cleaner API designConstructor: public ArraySegment(T[] array, int

offset, int count);Old API: public void Send ( byte[], int, int );New API: public void Send ( ArraySegment<byte> );

Speeding Things Up: Parsing Values

In this demo, we'll see how TryParse can save you precious milliseconds, when comparing it to the traditional Parse

routines

ThreadingSemaphore

• Resource counting for mutex’s// construct a semaphore with a count of 2Semaphore sem = new Semaphore(2);

private void UseResource {// Wait until a count is available…sem.WaitOne(); // the sem count is reduced by one

// other code …

// Release the count:sem.Release(); // the count is incremented by one

New Managed SolutionsManaged solutions which weren’t available in V2003

Threading

Console: Additional Features

In this demo, we’ll see additional Console features making the Console a more robust experience

Others…

• New String APIs, to make tasks easier, and make the most appropriate code easier– Remove( startIndex )– Contains ( someString )– Split ( char(), omitEmptyEntries )

• IO ACLs• Named Events in Threading• Timing out streams• IO: Decompression support• Transactions• RegularExpressions: character

class subtraction• Performant scenarios for resources

Summary

• Features have been introduced to provide:– An easier, better programming experience– Faster, more resource aware code– More managed solutions

• Focus has been on evolution, not revolution

Keep those requests coming!

• Focus has been on evolution, not revolution

Keep those requests coming!

Designer Features

• More in-situ design experience, reduce obligatory visits to– the property grid– toolbars– menus

• Streamline common tasks– reduce clicks– reduce amount of code necessary

Feature List

• Snaplines • Smart tags• New selection UI / Semi-transparent dragging• In-situ string property editing• Document Outline• Toolbox improvements• Control Position / Size in Statusbar

• Runtime Features– Visual Styles– GDI Text

Snaplines

• Replaces grid layout mode• In-situ alignment (natural extension of IDE toolbar items

“Align Tops”, etc.)• Like snaps to like (e.g. left border to left, etc.), exposes

margins/padding• Controls can expose “interesting points”

– TextBox and Label “baseline” snapline

Snaplines (cont)

• New features: – Respects the new padding and margin properties on

controls– These values will be set to Windows UI style

guidelines– Works for resize operations– Supports multiselection– Initial control creation

In-Situ String Editing

• Ability to edit a single property for all controls at once.• Similar to tab order editor in v1.1• Only works for string properties

Smart Tasks

• In-situ tasks, immediate• Extensible by 3rd parties

New Selection UI

• Reduced number of handles• Reduced size of UI• Rounded to look good with visual styles• ... but still tweaking ...

Dragging UI Improvements

• Real-time control rendering -- WYSIWYG• Semi-transparent

Document Outline View

• Not just for HTML anymore!• Allows easy control navigation, Z-order

modification, parenting

Toolbox Improvements

• Auto-population• Informative tooltips• Search/filter

Location / Size information in the Statusbar

Visual Styles

• Visual styles just work and are on by default– Setting the FlatStyle property is no longer necessary– Manifest is no longer necessary

• VS and the design experience will support visual styles• Visual Style APIs

– High level control based API for common drawing operations– Low level theme API for drawing theme parts– Low level API will be strongly typed for the beta– Works in semi trust

GDI Text Rendering

• GDI+ text is resolution independent– It doesn’t look like GDI text

• GDI text benefits from 10+ years of hardware acceleration

• GDI text has better globalization character set support on XP and above

GDI Text Continued

• Added System.Windows.Forms.GDI namespace• Added a new TextRender class for text

drawing– Provides a stateless API

• Added new WindowsFont class to encapsulate GDI fonts

• All Windows Forms controls use GDI text by default
