2. Darren Green Konesans Ltd

3. Agenda Extending SSIS –Types –Six Steps –Tasks –Debugging –Installation –When and Why?

4. Types Task Pipeline Component –Source –Destination –Transform Log Provider For Each Enumerator Connection Manager

5. Six Steps Create project Add references Add signing key Write code Compile Install

6. References Microsoft.SQLServer.ManagedDTS –Microsoft.SqlServer.Dts.Runtime Microsoft.SQLServer.DTSRuntimeWrap –Microsoft.SqlServer.Dts.Runtime.Wrapper Microsoft.SqlServer.PipelineHost –Microsoft.SqlServer.Dts.Pipeline Microsoft.SqlServer.DTSPipelineWrap –Microsoft.SqlServer.Dts.Pipeline.Wrapper Microsoft.SqlServer.Dts.Design –Microsoft.SqlServer.Dts.Runtime.Design

7. [ObjectAttribute(Information)] public class MyCustomObject : BaseClass { public override void BaseMethod() { // Custom code } Custom Objects - Template

8. Classes & Attributes Base ClassAttribute ConnectionManagerBaseDtsConnectionAttribute PipelineComponentDtsPipelineComponentAttribute ForEachEnumeratorDtsForEachEnumeratorAttribute LogProviderBaseDtsLogProviderAttribute TaskDtsTaskAttribute

9. Demo Simple Task

10. Tasks Methods –InitializeTask –Validate –Execute Properties –Use attributes, editors and type converters –Use connection GUID –Write only for security when required –Custom persistence for sensitive data or complex types

11. More Task Features Custom Events Custom Log Entries Breakpoints (IDTSBreakpointSite)

12. Create a Task User Interface Create UI class (Implement IDtsTaskUI) Create UI form Set task’s UITypeName attribute

13. Demo Simple Task User Interface

14. Advanced Task User Interfaces Microsoft.DataTransformationServices.Controls Microsoft.DataTransformationServices.Controls.dll DTSBaseTaskUI Base Form Class –DTSTaskUIHost Control, paged control –Class per page, implement IDTSTaskUIView

15. UI Classes & Attributes Interface / ClassNotes IDtsConnectionManagerUI Use Win Form IDtsComponentUI Use Win Form CManagedComponentWrapper ForEachEnumeratorUI UserControl IDtsLogProviderUI Not Supported IDtsTaskUI Use Win Form

16. Debugging Designer – Design time –Attach to devenv.exe Designer – Runtime –Attach to DTSDebugHost.exe Component Project – Runtime –Start external program C:\Program...\DTExec.exe /F "C:\...TestPackage.dtsx”

17. Debugging Tips Ensure class and strong name is fixed at start Must restart BIDS between builds, slow! Use DTExec for all runtime Use Post Build Event for install –copy "$(TargetPath)“ C:\Program... –gacutil.exe" /if "$(TargetPath)“ Ensure persistence complete

18. Installation Locations Designer Enumeration Folder –Designer location only (x86 Only) C:\Program Files\Microsoft SQL Server\90\DTS\ \Connections \LogProviders \ForEachEnumerators \PipelineComponents \Tasks Global Assembly Cache –Runtime loading by execution host

19. Install Platform Target 32-bit (x86) Locationx86x64IA64MSIL Program FilesDesign GACRun Install in Program Files for Designer Install in GAC for run-time Support for x86 specific targeted assemblies Support for Any CPU / MSIL

20. Install Platform Target 64-bit (x64) Locationx86x64IA64MSIL Program Files (x86)Design GACRun Support for x86 only targeted assemblies Support for x64 only targeted assemblies Support for Any CPU / MSIL Designer is x86/MSIL only Can side by side target assemblies

21. Install Platform Target Itanium (IA64) Locationx86x64IA64MSIL GACRun Support for IA64 Support for Any CPU / MSIL No designer support

22. 64-bit Tools Only Locationx86x64IA64MSIL Program Files (x86) GACRun No x86 file requirement No x86 DTSPath registry key MSI registry search is 32-bit No key, no tools, no designer, no file required!

23. Install Tips Use MSI builder of choice, e.g. VS, WiX Registry Search for DTS folder location HKLM\SOFTWARE\Microsoft\MSDTS\Setup\DTSPath C:\Program Files\Microsoft SQL Server\90\DTS\ Allow tools only installs, don’t require 32-bit key User Interfaces & Support Assemblies? –GAC Only Support Files? –Use special folders, CommonApplicationData Minimal UI, no options required

24. When to extend Reuse in multiple packages –Increased Development vs Lower Maintenance Access legacy resources (COM) Complex business logic More advanced code requirements Powerful IDE Language choice
