SetNtmsUIOptions Function

[Removable Storage Manager is no longer available as of Windows 7 and Windows Server 2008 R2.]

The SetNtmsUIOptions function modifies the list of computer names to which the specified type of UI is being directed for the given object.

Syntax

DWORD SetNtmsUIOptions(
  __in   HANDLE hSession,
  __in   const LPNTMS_GUID lpObjectId,
  __in   DWORD dwType,
  __in   DWORD dwOperation,
  __out  LPTSTR lpszDestination
);

Parameters

  • hSession [in]
    Handle to the session returned by the OpenNtmsSession function.

  • lpObjectId [in]
    Unique identifier of the object whose UI is being redirected. The object must be a container that can be a source for events. The object can be either be an application (a mount request triggered by the application), a library (a door open request in response to an eject) or a computer (all UI pertaining to the computer).

    To specify the computer container set the lpObjectId pointer to point to a buffer with the Removable Storage Manager's computer object GUID. To specify a particular library set it to point to a buffer with the library's GUID. To specify an application, pass in a NULL pointer. The identity of the application is determined by the session used in hSession. Note that an application can have multiple sessions open simultaneously. In this case, the value set applies only to the hSession session. In the case of a library or computer instance, settings persist until explicitly changed. Application rows are deleted when the session is closed.

  • dwType [in]
    This parameter can have one of the following values.

    Value Meaning
    NTMS_UITYPE_INFO

    UI messages that provide information. These include the work queue items that indicate progress. For example, mount requests.

    NTMS_UITYPE_REQ

    UI messages that are requests. These include the operator requests that handle media. For example, a request to inject new media.

    NTMS_UITYPE_ERR

    UI messages that give error information. These include operator requests that are related to error notification. For example, a request to clean the drive.

     

  • dwOperation [in]
    This parameter can have one of the following values.

    Value Meaning
    NTMS_UIDEST_ADD

    Add a new destination (computer name) to the list.

    NTMS_UIDEST_DELETE

    Remove a destination from the list.

    NTMS_UIDEST_DELETEALL

    Clear all destinations from the list. No UI for the object is generated. In this case, the destination argument is ignored.

     

  • lpszDestination [out]
    Multi-string that returns the names of the computers to which the UI is being redirected. This parameter cannot be NULL.

Return Value

This function returns one of the following values.

Value Meaning
ERROR_ACCESS_DENIED

Access to one or more RSM objects is denied.

ERROR_ALREADY_EXISTS

The given destination already exists in the list.

ERROR_INVALID_HANDLE

The session handle is missing or is not valid.

ERROR_INVALID_PARAMETER

lpdwSize or lpszDestination pointer is NULL, or lpObjectId is not a valid container, or dwType or dwOperation is not one of the three valid values.

ERROR_NOT_ENOUGH_MEMORY

An allocation failure occurred during processing.

ERROR_OBJECT_NOT_FOUND

The GUID specified by lpObjectId is not the GUID of any computer or library object in the database.

ERROR_SUCCESS

The function was successful.

 

Remarks

A call to SetNtmsUIOptions adds or removes a destination for a particular instance determined by the lpObjectId and dwType parameters.

  NTMS_UITYPE_INFO NTMS_UITYPE_REQ NTMS_UITYPE_ERR
Application Display work item progress UI for work items generated by this application. Display operator request UI for operator requests generated by actions taken by this application. Undefined. Applications cannot cause this sort of error event.
Library Display work item progress UI for work items associated with this library. Display UI for requests associated with this library. Display UI for errors associated with this library.
Computer Display informational UI in this instance of RSM running on this machine. Display a request-type UI in this instance of RSM. Display error-type UI in this instance of RSM.

 

Note that security checks are performed when calling SetNtmsUIOptions. When the computer object is specified you are required to have access with permission to modify the computer. When modifying a library's UI element you are required to have access with permission to modify the library object.

Note that there is no checking of destination strings. A call to with a destination name that's not a computer reachable from the computer on which SetNtmsUIOptions called returns success. A pointer to an empty string is taken to mean the local machine.
