Registering an Event Consumer Provider

To create a WMI event consumer provider you must register the __Win32Provider instance that represents your provider using an instance of __EventConsumerProviderRegistration. As a COM object, your provider must register with the operating system and WMI. The following procedure assumes that you have already implemented the registration process as described in Registering a Provider.

The following procedure describes how to register an event consumer provider.

  1. Create an instance of the __Win32Provider class that describes the provider.
  2. Create an instance of the __EventConsumerProviderRegistration class that describes the feature set of the provider.

    The properties that are defined by __EventConsumerProviderRegistration include the object path to the provider and the names of the logical consumer classes that the event consumer provider supports.

    Be sure to tag the class with both the Dynamic and Provider qualifiers. The Dynamic qualifier signals that WMI should use a provider to retrieve the class instances. The Provider qualifier specifies the name of the provider that WMI should use.

The following code example shows how to register an event consumer provider.

// Provider registration.
// ======================

instance of __Win32Provider as $P
    Name  = "MyEventConsumer";
    CLSID = "{4916157B-FBE7-11d1-AEC4-00C04FB68820}";

    DefaultMachineName = NULL;
    ClientLoadableCLSID = NULL;
    ImpersonationLevel = 0;

    PerUserInitialization = FALSE;
    Pure = TRUE;
    UnloadTimeout = NULL;

instance of __EventConsumerProviderRegistration
    Provider = $P;
    ConsumerClassNames = { "MyConsumer" };

Windows Server 2003:  Only administrators can register or delete an event consumer provider by creating an instance of __Win32Provider and __EventConsumerProviderRegistration.
