Object methods and properties

The object returned by the new() method can be used to invoke methods or retrieve properties in the same fashion as described in the documentation for the particular OLE class (eg. Microsoft Excel documentation describes the object hierarchy along with the properties and methods exposed for OLE access).

Optional parameters on method calls can be omitted by using undef as a placeholder. A better way is to use named arguments, as the order of optional parameters may change in later versions of the OLE server application. Named parameters can be specified in a reference to a hash as the last parameter to a method call.

Properties can be retrieved or set using hash syntax, while methods can be invoked with the usual perl method call syntax. The keys and each functions can be used to enumerate an object's properties. Beware that a property is not always writable or even readable (sometimes raising exceptions when read while being undefined).

If a method or property returns an embedded OLE object, method and property access can be chained as shown in the examples below.
