UnregisterDefaultFilterExtList Method

  • Article

The UnregisterDefaultFilterExtList method of the IFilterRegistration2 interface removes the list of file name extensions that are registered to use the default IFilter.

Parameters

pwcsOverride  [in] A pointer to a WCHAR that contains an override string, such as the application name.

pwcsMachineName   [in] A pointer to a WCHAR that contains the name of the computer on which the mapping is stored.

Exceptions

For a list of errors returned by Microsoft SharePoint Portal Server Search IFilter registration objects, see IFilter Administration Error Messages.

Remarks

The UnregisterDefaultFilterExtList method removes the registry settings that specify the file name extensions that explicitly use the default IFilter if no other IFilter registered for that file type succeeds.

If the pwcsOverride string is not null, the method removes the file name extensions registered with that override string. The pwcsMachineName string indicates the computer name from which the settings are removed.

Requirements

Platform: Microsoft Windows Server 2003
