What's New in JACOB 1.10

• Windows Processes
  • New proposed API to support ActiveXComponent connections to already running applications. Factory methods have been added to the ActiveXComponent to support this. (Feedback wanted)
• Variants
  • Variant now accept Java Dates in the constructor.
  • Redundant constructors removed
  • Experimental toJavaObject() method added that automatically converts to appropriate java type
  • Support added for "NOTHING", a Variant of type Dispatch with no value
  • Non functional getNull() and getEmpty() methods deprecated. They were void methods
• Event Callbacks
  • Jacob normally uses information in the registry to find the connection information needed to set up event callbacks. Excel and other programs don't put that information in the registry. A new optional parameter has been added to the DispatchEvents constructors that lets a user provide the location of the OLB or EXE that contains the information required to retrieve the events.
  • Event handlers can now return a Variant to calling MS Windows program. Event handlers that do not return an object should still be defined as being of type "void". This means that support for event handler's returning values should be backwards compatible with previous releases.
