Solution Use the appropriate custom attributes from the namespace. The sample contains a component that participates in automatic transactions. The component has a single method TranTest that instructs the transaction to succeed or fail based on an argument success. The sample also contains code that instantiates the component that participates in the automatic transaction. A checkbox on the form is used to specify the success parameter when the TranTest method is called. The C code is shown in Examples Example 6-1 and Example 6-2. Example 6-1. ServicedComponentCS Project File Namespaces variables and constants using using using . . . namespace Transaction public class SC0601 ServicedComponent AutoComplete public void TranTest bool success . . . Do some work. if success II don t need the next line since AutoComplete else II Vote to abort. II Raise an exception. throw new Error in Serviced Component 0601. Transaction aborted. Example 6-2.
