Tests existence of an Internet Explorer setting that is a registry key in a specified logical hive, allowing placeholders in the key’s name.
BOOL ExistsInHiveExtKey ( REFGUID Guid, HIVEID HiveId, UINT ArgCount, ...);
in which HIVEID is an enum in the SettingStore namespace.
The Guid argument specifies the setting to work on.
The HiveId argument specifies a logical hive for the setting. Refer to the general notes for supported cases.
The ArgCount argument specifies how many placeholders are provided as remaining arguments. Each placeholder is a PCWSTR.
The function returns TRUE if the setting exists in any logical hive, else FALSE.
The ExistsInHiveExtKey function is exported from IERTUTIL as ordinal 665 in version 8.0 and higher.
