Office SharePoint Designer 2007 a replacement for FrontPage is used as an aid in the rapid design and deployment of workflows. Office SharePoint Designer 2007 is specifically designed to help create and customize web sites and workflows built with SharePoint Products and Technologies. The Development process in SharePoint Designer is based on declarative rules-based code-free workflow editor. SharePoint Designer (SPD) gives list administrators business administrators and designers the ability to create workflows without writing any code. SPD exposes many of the workflow activities that ship with SharePoint as actions that users can string together into a sequential process. These actions are customized via sentences that describe the action and bind data to action parameters. However businesses will oftentimes need more custom functionality than the actions provided with SharePoint requiring them to write custom code that can run on the server. This guide describes how to write a custom code as an activity using the Visual Studio Extensions for Windows Workflow Foundation and expose it as an action in SPD. Activity refers to the basic building block of functionality in a Windows Workflow Foundation (WF) workflow. In Office SharePoint Designer 2007 however each activity appears as an action represented by a sentence that contains variables that the user can configure using drop-down menus and lookup dialog boxes. Users can also select conditions which are configurable conditional clauses that direct the flow of the workflow. As the user is selecting and configuring conditions and actions in the workflow interface Office SharePoint Designer 2007 generates the two files that actually represent the workflow class: The workflow markup file which contains markup language that describes the activities included in the workflow. The workflow rules file contains the business logic of the workflow in declarative rules form rather than as code. refer this links http://www.codeproject.com/KB/sharepoint/CustomActivity.aspx http://blogs.msdn.com/b/appfabric/archive/2011/08/14/how-to-create-a-custom-activity-designer-with-windows-workflow-foundation-wf4.aspx
