Syntax C++ DWORD SetNtmsDeviceChangeDetection( __in HANDLE hSession, __in HANDLE hDetectHandle, __in LPNTMS_GUID lpObjectId, __in DWORD dwType, __in DWORD dwCount ); Parameters hSession [in] Handle to the session returned by the OpenNtmsSession function. hDetectHandle [in] Device change detection handle from BeginNtmsDeviceChangeDetection , or NULL for a single poll. lpObjectId [in] Object identifier for the target device. This parameter can be one or more library, media type, or physical media GUIDs. All GUIDs must be the same type. dwType [in] Type of object identifiers specified in the lpObjectId parameter. This parameter can be one of the following values from the NtmsObjectsTypes enumeration type: NTMS_LIBRARY, NTMS_MEDIA_TYPE, or NTMS_PHYSICAL_MEDIA. dwCount [in] Number of object identifiers in lpObjectId. Return Value This function returns one of the following values. ValueMeaning ERROR_INVALID_HANDLEThe session or detection handle is not valid. ERROR_INVALID_PARAMETERThe object type is not valid. ERROR_INVALID_LIBRARYThe specified library was not found. ERROR_INVALID_MEDIAThe specified media or type was not found. ERROR_SUCCESSThe operator request has been canceled. Remarks The device can be specified directly by passing library GUIDs or indirectly by passing physical media or media type GUIDs. When using the indirect specification, all stand-alone libraries that could contain the media or media type are detected. All devices specified continue to be detected until the device change detection handle is closed using the EndNtmsDeviceChangeDetection function. This function can also be used to poll for changed media in the specified devices. This is typically used by a UI when opening a leaf node or implementing a refresh option.
