Many of the BizTalk Server examples in this issue would not work without strong typing, which provides crucial information about the component.
Interfaces are simply the properties, events and methods of a COM object. Assume that you have an application that can be extended using custom objects.
Those objects would need to fulfill certain criteria. For instance, the object may be required to have Execute and Configure methods. The application relies on those methods being present.
In other words, it defines that the interface for the custom extension objects consists of those two methods.

But, the application itself doesn't do anything with those two methods. It simply calls them, leaving it up to the extension objects to implement code for those two methods.
Thus, the terminology "implementing an interface". Let's look at an visual basic foxpro 6 0 to make this clearer. The husband class subscribed to the wife's TakeOutGarbage event. Using that same scenario, let's see visual basic foxpro 6 0 we can create this husband object with Visual FoxPro 7.
The TakeOutGarbage method code in the husband class in Visual FoxPro 7 would be very similar to the Visual Basic code found on page 16, and would look like this: In fact, if we did not include the "AS String" to define the What parameter, COM would produce an error, since our interface does not match the interface we claim it matches parameters are part of the interface definition.

All of the methods belonging to the implemented interface start with the name of the interface, followed by an underscore and the actual method visual basic foxpro 6 0. This class can have additional properties and methods and can, in fact, implement multiple interfaces.
The component that defines the interface contains only abstract events and methods? Here is how the code for the wife object would look in Visual FoxPro 7 compare to the Visual Basic code that appears on page 14 in the Spring issue: It simply defines the interface. Since the publisher has no knowledge of the subscribers, the events are said to be "loosely coupled".
This object would be a publisher. You could then program several subscriber objects to react to this event.
