__InstanceOperationEvent class

Applies to: desktop apps only

The __InstanceOperationEvent system class serves as a base class for all intrinsic events that relate to an instance.

The following syntax is simplified from Managed Object Format (MOF) code and includes all inherited properties. Properties are listed in alphabetic order, not MOF order.

Syntax

Copy

class __InstanceOperationEvent : __Event
{
  uint8  SECURITY_DESCRIPTOR[];
  object TargetInstance;
  uint64 TIME_CREATED;
};

Members

The __InstanceOperationEvent class inherits from __Event. __InstanceOperationEvent also has these types of members:

Properties

Properties

The __InstanceOperationEvent class has these properties.

SECURITY_DESCRIPTOR

Data type: uint8 array
Access type: Read-only

Descriptor used by the event provider to determine which users can receive the event. This property is inherited from __Event.

Windows 2000, Windows NT Server, and Windows Me/98/95: This property is not available.

TargetInstance

Data type: object
Access type: Read-only

Instance affected by the event. For creation events, this is the newly created instance. For modification events, this is the new version of the changed instance. For deletion events, this is the deleted instance.

TIME_CREATED

Data type: uint64
Access type: Read-only

Unique value that indicates the time at which the event was generated. This is a 64-bit value that represents the number of 100-nanosecond intervals after January 1, 1601. The information is in the Coordinated Universal Times (UTC) format. This property is inherited from __Event.

Windows 2000, Windows NT Server, and Windows Me/98/95: This property is not available.

For more information about using uint64 values in scripts, see Scripting in WMI.

Remarks

The __InstanceOperationEvent class is derived from __Event.

Instances of __InstanceOperationEvent are not created; only instances of its subclasses are created. The following classes derive from __InstanceOperationEvent:
