Scenario: Holding State in the MoveMoney Component

[This product will work only on Windows NT 4.0 versions and earlier. For Windows 2000 and later, see COM+ (Component Services).]

Building stateful objects is a useful approach in application design. However, such design can have performance trade-offs. This section demonstrates how holding state in objects affects the application behavior within the Microsoft Transaction Server run-time environment.

You will modify the MoveMoney component to be stateful by adding the StatefulPerform function to MoveMoney. StatefulPerform is called when you click Stateful MoveMoney on the Sample Bank client. This new function causes MoveMoney to retain data in member variables between method calls.
