Presenter  Michael Washington   Core member of DotNetNuke®  Creator of the Creating a DotNetNuke® Module For absolute beginners! series of tutorialsCreating a DotNetNuke® Module For absolute beginners!

Agenda  DotNetNuke® Overview  The DAL+  Demo  Questions

DotNetNuke® Overview  Open Source Software Project ( BSD License )  Windows Server / ASP.NET platform  Released December 24, 2002  Web Application Framework  Based on N-Tier, Object Oriented, Best Practice architecture  Used in private sector, public sector, military, non-profit, community, and individual web sites  Active business ecosystem with hundreds of vendors offering products and services  Incubator for complementary Open Source Projects  Support for ASP.NET 1.1 and ASP.NET 2.0

Modules  Applications for managing a specific type of portal Content  Allows you to extend DotNetNuke without modifying the core framework.  Written in.NET code ( C#, VB.NET, etc… )  Private Assemblies  Run-time deployment

Modules Design Create Module Project (Developer) Replace Implement Custom Functionality (Developer) Package Package Module for Installation (Developer) Deploy Install into Portal (Admin)

Previous development process (DNN 3)  Configuration was difficult  Data Access Layer was difficult to understand

New development process (DNN 4)  Configuration is no longer needed using the new ASP.NET 2.0 Website project model  The DAL+ simplifies the Data Access Layer

The DAL+  You no longer have to code a separate data provider  It adds “Generic Methods” to ease module development. ExecuteNonQuery - Used to execute a stored procedure that will not return a value. ExecuteReader - Used to execute a stored procedure that will return multiple records. ExecuteScalar - Used to execute a stored procedure that will return a single value. ExecuteSQL - Used to execute an sql statement.

The DAL+ Public Function GetItems(ByVal ModuleId As Integer) As ArrayList Return CBO.FillCollection(DataProvider.Instance().ExecuteReader("GetItems",ModuleId), GetType(ItemInfo)) End Function

Demo  Create DAL+ “Things For Sale” Module
