Rich User Control development

Rich support for Custom Controls

What is “smart”

Local resources and user experience

Offline capable

Intelligent deployment and update

Multithreaded

Crash Proof

Visual Studio 2005

DataNew data-bound controls

Schema-based typed-data set designerSupport for iterative maintenance of generated data-code

Partial types for maintainable customizations of auto-generated code

Reduced need for “mapping” or “glue” code

Server explorerIntegrated data manipulation

ClickOnce Deployment

ClickOnce application deployment published on a web or file server

Client follows link to serverhttp://www.tempuri.org/my.application

Application deployed locally in user’s profile directory & executed

Subsequent executions check for updates & execute local install

Other parallels to web-applicationsApplications are isolated per-userCan be executed with limited local permissions

Locally executed, rich features

ClickOnce Features

Follow a link to install an applicationAutomatic w/minimal or no decision points

web-style deployment

Automatic update of application

Security isolation and optional restricted permissions

Non-administrative installs

ClickOnce & VS 2005

Project Settings Publish tabSet deployment location

Configure data files for deployment

Other settings: version, online-only or online-offline, CD installations and other details

Project Settings Security tabCalculating permissions required by your application to function

Also add permissions using SecurityException at runtime

Setting permissions in the manifest required to run

Partial trust and full trust supported

Application Updates

Auto-update deployment optionsBefore application launch, or

Update check occurs after app-launch

Scheduled update checksWeekly, monthly, etc.

Project Settings Publish tabSettings for update checking

ToolStrips

Replaces MainMenu, ContextMenu, ToolBar and StatusBar

HWNDless architecture

Same OM across all containers

System and professional renderers

Datagridview

Replaces DataGrid

Extensible and FlexibleBound, Unbound, Virtual, Mixed

Eleventy billion PMEs

Cell-based, not Column-basedCell styles (Font, Color, Formatting)

Cell-level eventsMouse, Formatting, Validate, Error, others...

Custom Column Types

High performanceDisplay, scrolling, updates

Backgroundworker

BackgroundWorkerSimplify creating responsive applications

Easier to perform long running tasks without “freezing” the UI

Simplify Thread use in Windows Forms applications

Automatically acquired ThreadPool Thread

DEMO

What Is: Occasionally Connected

Empowering users to leverage their computer, applications, data and files regardless of network availability

Application proactively retrieves necessary data necessary to work offline

As the network comes available, the application will automatically sync their work and log conflicts for the user to resolve

Network operations occur in the background so the user can stay focused on their task

Example: Outlook 2003

Resources Needed Offline

DataA subset of the data from the server(s)

Heterogeneous Sync (SQL Server, Oracle, DB2, …)

FilesNot all data exists within the database

Media files, Office Files, …

Application Messaging (Web Services, WCF, …)Ability to queue outbound messages

Ability to async process inbound messages

Read Only Informational/Reference Data ServicesAbility to pre-fetch data from existing services

Deploying SQL Server Mobile

SQL Server Mobile EngineAdd runtime dlls to project (sqlce*.dll) C:\Program Files\Microsoft Visual Studio 8\Common7\IDE

File size <1.4mb

Set files to Copy to Output Directory = Copy if newer

ADO for SQL Server MobileAdd reference to Microsoft SQL Mobile

Located in: C:\Program Files\Microsoft Visual Studio 8\ _ Common7\IDE\PublicAssemblies\System.Data.SqlServerCE.dll

File Size ~224k

How - To Sync

Roll your ownUltimate in flexibilityHighest cost to develop and maintain

Merge ReplicationMost power, broadest features for different data partitions, spans all devicesNeed DBO/DBA privileges, must “own” server

Remote Data Access (RDA)Easy entry point for well partitioned data, no config to databaseLimited to SQL Server Mobile
