6. What makes VS extensible? Interfaces!! Paul Sturgill - Building a Visual Studio Add-in

7. Interfaces • Extensibility.IDTExtensibility2 • OnAddInsUpdate – List of add-ins change • OnBeginShutdown – IDE shuts down • OnStartupComplete – IDE startup complete • OnDisconnection – Add-in unloads from IDE • OnConnection – Add-in is loaded into IDE • IDTCommandTarget • Exec – invokes Add-in behavior (menu item) • QueryStatus – listing available add-ins Paul Sturgill - Building a Visual Studio Add-in

8. NEVB Demo Add-in • Features: • Code manipulation • IDE Event tracking • Launched Window application • Tool Window Paul Sturgill - Building a Visual Studio Add-in

9. Start Demos Paul Sturgill - Building a Visual Studio Add-in

10. Visual Studio 2005 (Whidbey) • Main goal is less COM • No more Regsvr32 • Use XML file to define an Addin • No more shim control for Toolwindow • New CreateToolWindow2 method • Toolbar accepts different types of controls • Combo box, checkbox, etc… not just buttons Paul Sturgill - Building a Visual Studio Add-in

11. 3 Steps to creating Pluggable Software Define Common Interface Implement Interface Create hosting application Paul Sturgill - Building a Visual Studio Add-in

12. Define Custom Interface Public Interface ICustomAddin Function Start() as Boolean Function Stop() as Boolean End Interface *Equivalent to IDTExtensibility2 Interface Paul Sturgill - Building a Visual Studio Add-in

13. Implementation of Interface Public Class MyCustomAddin Implements ICustomAddin Public Function Start() as Boolean Implements ICustomAddin.Start ‘ Do something here when the add-in starts End Function Public Function Stop() as Boolean Implements ICustomAddin.Stop ‘ Do something here when the add-in stops End Function End Class *Equivalent to custom VS Add-in Paul Sturgill - Building a Visual Studio Add-in

14. Hosting Application Dim assem As Reflection.Assembly = Reflection.Assembly.LoadFrom(“c:\plugins\mycustomplugin.dll”) Dim oAddin As Object Dim iAddin As PluginLibrary.iCustomAddin oAddin = assem.CreateInstance(“MyCustomAddin.MyCustomAddin”) iAddin = CType(oAddin, PluginLibrary.ICustomAddin) iAddin.Start() * Equivalent to Visual Studio as a hosting application Paul Sturgill - Building a Visual Studio Add-in
