DISPID

Used by IDispatch::Invoke to identify methods, properties, and arguments.

typedef LONG DISPID;

The following DISPIDs have special meaning:

DISPID	Description
DISPID_VALUE	The default member for the object. This property or method is invoked when an OLE Automation controller specifies the object name without a property or method.
DISPID_NEWENUM	The _NewEnum property. This special, restricted property is required for collection objects. It returns an enumerator object that supports IEnumVariant and should have the restricted attribute specified in ODL.
DISPID_EVALUATE	The Evaluate method. This method is implicitly invoked when the OLE Automation controller encloses the arguments in square brackets. For example, the following two lines are equivalent: x.[A1:C1].value = 10 x.Evaluate("A1:C1").value = 10 The Evaluate method has the dispatch ID DISPID_EVALUATE.
DISPID_PROPERTYPUT	The parameter that receives the value of an assignment in a property "put."
DISPID_CONSTRUCTOR	The C++ constructor function for the object.
DISPID_DESTRUCTOR	The C++ destructor function for the object.
DISPID_UNKNOWN	Value returned by IDispatch::GetIDsOfNames to indicate that a member or parameter name was not found.
