Developing on Microsoft Office

A unified solutions platform for building Office Business Applications that make line-of-business systems, enterprise data and workflows accessible and relevant to users. Premiere developer tools for developing Office Business Applications and scalable enterprise grade solutions utilizing Visual Studio and Microsoft Office

Integrated design-time experience Increased security through .NET Framework Document-level & application-level task pane customizations … Support for managed controls Support for host controls Ability to add controls at design-time or dynamically at run-time … Quick development Competitive advantage Strength of two major products …

Scenarios Tools Post 2003 N-tier Distributed Apps Complex document add-ins (high reuse) Simple document add-ins (high reuse) Simple document add-ins (low reuse) Macro modify Macro record/replay Advanced app-level add-ins Simple app-level add-ins Application repurposing VBA (as intended) VBA (as applied) Market Gap Tools Pre 2003 Scenarios Complexity

Reasons for Using VSTO vs. VBA * There are no pending plans to retire VBA at this time VBA IS A 1990’S TECHNOLOGY Limited functionality and flexibility Code in document = no source code/version control VISUAL STUDIO TOOLS FOR OFFICE IS 100% .NET Choice of Visual Basic .NET or C# Pro dev environment & tools; access to .NET Framework VSTO SOLUTIONS ARE SECURE VBA has a casual security model = high potential security risk VSTO solutions employ the .NET Security model VSTO SUPPORTS BUILDING SCALABLE OFFICE BUSINESS SOLUTIONS Take advantage of the 2007 Office system development platform Utilize the full benefits of the Visual Studio development environment

Ask These Questions What business problem does this VBA solution address? What parts of this solution, if any, can I leave in VBA? Does it make sense to move this VBA solution to VSTO?

Call VSTO from VBA Developers enable VBA via COM Interop Interop implemented at design time Developers can then call VSTO from VBA with IntelliSense after building the project

Custom Task Panes VSTO 2005 SE provides app-level custom task panes Create custom task panes with an add-in Add-in support & task pane support for Project, Excel, InfoPath, Outlook, PowerPoint, Word Custom task panes appear in the main application window or (Outlook) inspectors Populate custom task pane with UserControls Populate user controls with Winform controls

Outlook Form Regions Implement a custom form region with an add-in Runtime and design-time support

Outlook Form Region Wizard VSTO simplifies and speeds up Outlook form region design and configuration process with a visual designer Achieve maximum form region design flexibility with VS visual designer Configure your form region with a simple, intuitive wizard Run and debug your form region right from Visual Studio [F5] No need to handle manifest XML, OFS files, registry entries, etc. manually Option to import Outlook-created OFS file

Linq “ It is a mistake to try to look too far ahead. The chain of destiny can only be grasped one LINQ at a time.” ~Sir Winston Churchill (1874 - 1965) – modified slightly ;)

Linq has been over 7 years in the making ObjectSpaces PDC 2001 Supposed to be part of .Net 2.0 Linked to WinFS C – Omega Researched by Erik Meijer and Worlfram Schulte Released as a preview in 2004 Language Extensions Worked a lot with XML, Streams, Anonymous Structs Linq Backed by Anders Hejlsberg - Distinguished Engineer (Only 16 ever) – Chief Designer of C# Matt Warren – Chief Engineer Luca Bolognese– Lead Developer Very Brief Linq History

Integrate Objects, Relational Data & XML SQL and Xquery-like power in C# and VB Extensible Model for languages Type Safety Extensive IntelliSense support Debugger Support Run on the .Net 2.0 CLR 100% backwards compatible Linq Goals

Language INtegrated Query (LINQ) LINQ enabled data sources LINQ To Objects Objects LINQ To XML <book> <title/> <author/> <price/> </book> XML LINQ enabled ADO.NET LINQ To DataSets LINQ To SQL LINQ To Entities Relational Others… VB C# .NET Language-Integrated Query

Linq Query Syntax “ Syntax, my lad. It has been restored to the highest place in the republic.” ~John Steinbeck

Linq Syntax – Why we started where we did var query = dc.Recipes .W here (r => r.Title.Contains( “Chocolate” ) ) .S elect (r => new{ r .Title, r.NumberOfServings}) ; Extension methods Lambda expressions Object initializers Anonymous types Implicitly Declared Local Variables Extension methods

Standard Query Operators These work similarly to their SQL counterparts Select Where OrderBy/ThenBy OrderByDescending/ThenByDescending GroupBy Count Sum/Min/Max/Average

Set Based Query Operators Combine two sets of elements Union Returns all distinct elements in both sets Intersection Returns only elements belonging to both sets Except Returns elements in Set A but not in Set B Repeat Returns multiple copies of a set of elements Distinct Removes duplicate elements

Projection That Creates a Nested 1-Many Collection A query can be nested inside another query to produce a 1-Many Collection var q = from c in db.Customers where c.City == "London" select new { c.CompanyName, c.Phone, OrderDates = ( from o in c.Orders select o.OrderDate) .Take(5) }; foreach( var c in q ) { Console.WriteLine( c.CompanyName ); foreach( od in c.OrderDates ) Console.WriteLine( od ) }

LINQ Queries Are Lazy Assigning a query to an IEnumerable<T> variable doesn’t execute the query When user iterates over members of the collection, each query operator executes as many times as needed to retrieve the next element Hence the data can change while elements are still being retrieved Use .ToList<T> or .ToArray<T> to force iteration over the entire query in one statement Creates a snapshot copy of the original data

Every syntactic query expression in C# begins with a " from " clause and ends with either a " select " or " group " clause. The " from " clause indicates what data you want to query. The " select " clause indicates what data you want returned, and what shape it should be in. For example, let's look again at the query against the List<Person> collection: Syntax – From a list (Linq to Objects)

If we query from a Database we use the same syntax. We will cover the DataContext soon Syntax – From a DB

What goes on under the covers? You write this : Linq sends this to the database Syntax – Under the hood

What about complex queries? You write this : Linq sends this to the database Syntax – Under the hood Extension methods

Why are SELECT and FROM Reversed In C# 3.0, the IDE still doesn’t do background compilation, so it has to parse code line-by-line Putting SELECT before FROM would prevent IntelliSense from knowing what can be SELECTed

Defining the Data Model Classes

The DataContext Object is what links the class entities to the database entities. This can be done by hand OR by using the Linq to SQL Class Model The DataContext Object

Enabling a class [Table(Name = "Customer")] public class Customer { private int _Id; private string _Name; private string _Phone; [Column(Id = true, Name = "Id”)] public int Id { get { return _Id; } set { _Id = value; } } [Column(Name = "Name")] public string Name { get { return _Name; } set { _Name = value; } } [Column(Name = "PhoneNumber")] public string Phone { get { return _Phone; } set { _Phone = value; } } } But doing this manually is not required.!

Summary Microsoft Office is a unified solutions platform for building Office Business Applications that make line-of-business systems, enterprise data and workflows accessible and relevant to users VSTO is the premiere developer tool for developing Office Business Applications and scalable enterprise grade solutions utilizing Visual Studio and Microsoft Office VSTA is the key developer tool technology that enables ISVs to provide rich customization capabilities within their products and solutions
