Informs the schema subsystem of the removal of a property description schema (.propdesc) file, using a file path to the .propdesc file on the local machine.
Type: LPCWSTR
Pointer to the file path for the .propdesc file on the local machine.
Type: HRESULT
Returns one of the following values.
| Return code | Description |
|---|---|
|
Indicates schema is unregistered. |
|
Indicates calling context does not have proper privileges. |
Call this method when the file is being uninstalled from the machine. Typically, a setup application calls this method before or after uninstalling the .propdesc file. This method can be called after the file no longer exists.
Call IPropertySystem::RefreshPropertySchema in order for the newly-unregistered schema files to be unincorporated from the search index and the schema subsystem cache.
This method fails with E_ACCESSDENIED if the calling context does not have proper privileges, which include write access to the local machine. It is the caller's responsibility to obtain privileges via least-privileged user account (LUA) mechanisms.
