Used by IDispatch::Invoke to identify methods, properties, and arguments.
typedef LONG DISPID;
The following dispatch identifiers (DISPIDs) have special meaning.
| DISPID | Description |
|---|---|
| DISPID_VALUE | The default member for the object. This property or method is invoked when an ActiveX client 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 Object Description Language. |
| DISPID_EVALUATE | The Evaluate method. This method is implicitly invoked when the ActiveX client encloses the arguments in square brackets. For example, the following two lines are equivalent:
The Evaluate method has the DISPID DISPID_EVALUATE. |
| DISPID_PROPERTYPUT | The parameter that receives the value of an assignment in a PROPERTYPUT. |
| DISPID_CONSTRUCTOR | The C++ constructor function for the object. |
| DISPID_DESTRUCTOR | The C++ destructor function for the object. |
| DISPID_UNKNOWN | The value returned by IDispatch::GetIDsOfNames to indicate that a member or parameter name was not found. |
