OperationHandle :: Execute - Execute operation
The function executes a predefined operation. The result is returned as property handle.
It is possible to pass a property handle as calling object. If no property handle is passed the one that was used for creating the operation is used as calling object. When using another property handle than the originating one, the type of the properties must be identical.
The result of the operation can be provided with the GetResult () function.

logical OperationHandle :: Execute ( OperEnvironment *operenv, PropertyHandle &call_object, ParmList *parameters )
- operenv - Pointer to operation environment
- call_object
- Calling object
The calling object is passed as property handle, which provides the instance(s) for calling the operation.
- parameters
- Parameter list
A parameter list is a list of property handles, where each property handle represents a parameter. Thus, parameters may be simple values, but also complex data structures or collections.

Execute operation without parameters
logical OperationHandle :: Execute ( )
