IMSAdminBase::GetAllData

  • Artículo

The IMSAdminBase::GetAllData method retrieves all data associated with a key in the metabase. This includes all values that the key inherits.

HRESULT GetAllData(
      METADATA_HANDLE hMDHandle,
      LPCWSTR pszMDPath,
      DWORD dwMDAttributes,
      DWORD dwMDUserType,
      DWORD dwMDDataType,
      DWORD* pdwMDNumDataEntries,
      DWORD* pdwMDDataSetNumber,
      DWORD dwMDBufferSize,
      Unsigned CHAR* pbMDBuffer,
      DWORD* pdwMDRequiredBufferSize
);

Parameters

  • hMDHandle
    Specifies a handle to the metabase. This can be either METADATA_MASTER_ROOT_HANDLE or a handle, with read permission, returned by the IMSAdminBase::OpenKey method.

  • pszMDPath
    Specifies the path of the key with which the data to be retrieved is associated, relative to the path of hMDHandle. For example, if the handle references the /LM key, you could specify the Web services subkey using the path /W3SVC.

  • dwMDAttributes
    The flags, contained in the METADATA_RECORD structure, used to get the data.

  • dwMDUserType
    Specifies the user type of the data. If not set to ALL_METADATA, only data of the specified user type will be returned.

    The following user types are defined for IIS:

    User type

    Meaning

    ALL_METADATA

    Return all data, regardless of user type.

    ASP_MD_UT_APP

    The entry contains information specific to ASP application configuration.

    IIS_MD_UT_FILE

    Return only data specific to a file, such as access permissions or logon methods.

    IIS_MD_UT_SERVER

    Return only data specific to the server, such as ports in use and IP addresses.

    IIS_MD_UT_WAM

    The entry contains information specific to Web application management.

  • dwMDDataType
    Specifies the type of data to retrieve. If dwMDDataType is not set to ALL_METADATA, only metadata of the specified type will be returned. This parameter can be one of the following values:

    Data type

    Meaning

    ALL_METADATA

    Retrieve all data, regardless of type.

    BINARY_METADATA

    Binary data in any form.

    DWORD_METADATA

    An unsigned 32-bit number.

    EXPANDSZ_METADATA

    A null-terminated string that contains unexpanded environment variables, such as %PATH%.

    MULTISZ_METADATA

    An array of null-terminated strings, terminated by two null characters.

    STRING_METADATA

    A null-terminated ASCII string.

  • pdwMDNumDataEntries
    Points to a DWORD that receives the number of entries copied to pbBuffer.

  • pdwMDDataSetNumber
    Points to a number associated with this data set.

  • dwMDBufferSize
    Specifies the size, in bytes, of pbMDBuffer.

  • pbMDBuffer
    Points to a buffer that receives the data. If the method call is successful, the buffer will contain an array of METADATA_GETALL_RECORD structures.

  • pdwMDRequiredBufferSize
    Points to a DWORD that contains the buffer length required, in bytes.

Return Values

Returns an HRESULT that contains one of the following values:

Value

Description

E_ACCESSDENIED

Access is denied. Either the open handle does not have read or write permission as needed, or the user does not have sufficient permissions to perform the operation.

HRESULT_FROM_WIN32(ERROR_INSUFFICIENT_BUFFER)

The buffer passed into the method call is too small to receive the data.

E_INVALIDARG

The parameter is incorrect.

HRESULT_FROM_WIN32(ERROR_PATH_NOT_FOUND)

The specified path was not found.

S_OK

The method succeeded.

Remarks

On non-Intel platforms the DWORD data is aligned; this may not be true on remote clients.

The handle, METADATA_MASTER_ROOT_HANDLE, provides no guarantee against multiple thread access. If your application requires a constant data state, use a handle returned by IMSAdminBase::OpenKey.
