Figure 6-5. Select the newly defined IWorkflowAsService interface. Set IsActivating to True, because the first WebServiceInput activity within a workflow must have the IsActivating property set to True. From the drop-down list next to the Method Name property, choose AcceptValue. This links the call to the WebServiceInput activity to the interface. When an application using this Web service makes a call to this Web service and executes AcceptValue, the workflow engine will know to call this WebServiceInput activity. Finally, from the drop-down next to InputValue under the parameters, select IntInputValue. Click the Promote Bindable Properties link at the bottom of the Properties window. Click the ellipse next to the InputValue property and choose ValueEntered from the Bind Properties dialog box. This ties the value passed in as a parameter to AcceptValue to the ValueEntered variable defined within the workflow. The properties of the WebServiceInput activity look like Figure 6-6. Add a WebServiceOutput activity to the workflow. Leave the name as the default. Use the drop-down next to InputActivityName to select WebServiceInputActivity1. This property ties the two activities together, so the input activity is receiving information, the output is sending the information, and it s the same information. Click the Promote Bindable Properties link at the bottom of the Properties window. Click the ellipse next to the Return Value property and choose ValueEntered from the Bind Properties dialog box. Again, this ties the value returning to the application that calls this Web service to the variable declared within this class.

Figure 6-6. Properties for the WebServiceInput activity Next, click GenerateHandlers at the bottom of the Properties window. This generates code to be executed when the activity is executed. When the sub is created, add IntInputValue = IntInputValue + 10. This simply adds 10 to the value provided by the calling application. Now the workflow is complete. The workflow will accept a value, add 10 to that value, and return it to the calling application. This simple example shows how you can use a workflow as a Web service. The final step to make a workflow into a Web service is to publish the workflow as a Web service. To do this, right-click the project name within the Solution Explorer and choose Publish as Web Service. A solution is created within the Solution Explorer, and all the necessary files are also created. To view the created Web service, right-click the file with the ASMX extension (VBAsWebServiceSequentialLibrary.WorkflowAsService_WebService.asmx) and choose View In Browser. This opens the ASMX file in the browser. Click the AcceptValue link to test the AcceptValue method. Enter 10 as the InputValue and click the Invoke button. The result of 20 appears in the XML file. This shows the workflow working as a Web service.

his chapter will cover how to interact with a workflow from a Windows or ASP.NET application. The previous chapters have explained the various types of workflow and all the activities that can be used within a workflow. The previous chapters have also shown a simple example of how to use each type of activity and workflow. Beginning with this chapter, you ll start to build more complex workflows and learn to create a real-world application from a workflow. Besides showing you how to interact with a workflow, this chapter will also cover how to handle faults within workflows, and how to roll back work already performed by a workflow if a fault occurs.
