Version:
    Last Modified: March 15, 2017

    Enumerates the values for a specific key or subkey.

    Caution  

    Incorrectly modifying the registry can damage Windows or prevent you from starting Windows.

    Programming Patterns

    You can wire the value info output of the Query Registry Key Info node to the Enum Registry Values Simple node to get the value information of a specific key or subkey.

    connector_pane_image
    datatype_icon

    reference in

    Reference to the open registry key.

    datatype_icon

    retrieve data

    A Boolean that determines whether this node retrieves data and data types.

    True Retrieves data and data types. The node also returns DWORD data and string/binary data in addition to values and simple data types.
    False Does not retrieve data and data types.

    Default: False

    datatype_icon

    value info

    Set of parameters describing the set of values and data.

    datatype_icon

    numValues

    Number of values under the key specified by hKey.

    datatype_icon

    maxValueNameLen

    Length of the longest value name under the key specified by hKey.

    datatype_icon

    maxValueDataLen

    Length of the longest datum under the key specified by hKey.

    datatype_icon

    error in

    Error conditions that occur before this node runs.

    The node responds to this input according to standard error behavior.

    Standard Error Behavior

    Many nodes provide an error in input and an error out output so that the node can respond to and communicate errors that occur while code is running. The value of error in specifies whether an error occurred before the node runs. Most nodes respond to values of error in in a standard, predictable way.

    error in does not contain an error error in contains an error
    If no error occurred before the node runs, the node begins execution normally.

    If no error occurs while the node runs, it returns no error. If an error does occur while the node runs, it returns that error information as error out.

    If an error occurred before the node runs, the node does not execute. Instead, it returns the error in value as error out.

    Default: No error

    datatype_icon

    DWORD data

    An array of data of Windows registry type DWORD.

    datatype_icon

    reference out

    Reference to the open registry key.

    datatype_icon

    values

    An array of value names.

    datatype_icon

    simple data types

    An array of simplified Windows registry data types.

    datatype_icon

    error out

    Error information.

    The node produces this output according to standard error behavior.

    string/binary data

    An array of data of Windows registry type String or Binary .
