wwDotNetBridge Examples

Allows you to capture events on a source object, by passing in a callback handler that maps the events of the target object with corresponding methods on the handler.

To handle events:

• Create an Event Handler Object
  Create a Custom class that implements methods that match the events of the .NET object that fires events with a On<EventName> prefix. Each 'asdd' method's parameters should match the parameters of the .NET event delegate. You only need to implement the methods you want to listen to - other events are ignored.

• Create an Event Subscription
  Call loBridge.SubscribeToEvents() which binds a .NET event source object to a FoxPro event handler.

• Continue running your Application
  Events are handled asynchronously in .NET and run in the background. Your application continues running and as events fire in .NET, the On<Event> methods are fired on the Event Handler object in FoxPro.

• Unsubscribe from the Event Subscription
  When you no longer want to listen to events, call loSubscription.UnSubscribe(). Make sure you do this before you exit FoxPro or you may crash VFP on shutdown.
