  • 11. What About VBA?
  • 12. 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
  • 13. 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
  • 14. 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?
  • 15. 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
  • 16. VSTO and 2007 Office System
  • 17. 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
  • 18. Outlook Form Regions
    • Implement a custom form region with an add-in
    • Runtime and design-time support
  • 19. 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
  • 20. Visual Ribbon Designer Property Grid Ribbon Control Toolbox Design Surface
  • 21. Building a VSTO Project
  • 22. 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 ;)
  • 23.
    • 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
  • 24.
    • 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
  • 25. 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
  • 26. Channel 9 Videos Future of Languages : Anders Hejlsberg, Herb Sutter, Erik Meijer, Brian Beckman http://tinyurl.com/ 513778
  • 27. Linq Query Syntax “ Syntax, my lad. It has been restored to the highest place in the republic.” ~John Steinbeck
  • 28. 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
  • 29. Standard Query Operators
    • These work similarly to their SQL counterparts
      • Select
      • Where
      • OrderBy/ThenBy
      • OrderByDescending/ThenByDescending
      • GroupBy
      • Count
      • Sum/Min/Max/Average
  • 30. 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
  • 31. 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 == &quot;London&quot; 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 )
    • }
  • 32. 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
  • 33.
    • Every syntactic query expression in C# begins with a &quot; from &quot; clause and ends with either a &quot; select &quot; or &quot; group &quot; clause. 
      • The &quot; from &quot; clause indicates what data you want to query. 
      • The &quot; select &quot; 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)
  • 34.
    • If we query from a Database we use the same syntax.
    • We will cover the DataContext soon
    Syntax – From a DB
  • 35.
    • What goes on under the covers?
    • You write this :
    • Linq sends this to the database
    Syntax – Under the hood
  • 36.
    • What about complex queries?
    • You write this :
    • Linq sends this to the database
    Syntax – Under the hood Extension methods
  • 37. 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
  • 38. Defining the Data Model Classes
  • 39.
    • 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
  • 40. Enabling a class
    •   [Table(Name = &quot;Customer&quot;)]
    •     public class Customer
    •     {
    •         private int _Id;
    •         private string _Name;
    •         private string _Phone;
    •  
    •          [Column(Id = true, Name = &quot;Id”)]
    •         public int Id { get { return _Id; } set { _Id = value; } }
    •  
    •         [Column(Name = &quot;Name&quot;)]
    •         public string Name { get { return _Name; } set { _Name = value; } }
    •  
    •         [Column(Name = &quot;PhoneNumber&quot;)]
    •         public string Phone { get { return _Phone; } set { _Phone = value; } }
    •     }
    But doing this manually is not required.!
