    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

    registry view

    Value that specifies whether to open a 32-bit key or a 64-bit key on a 64-bit operating system.

    Name Value Description
    Default 0 This node selects the type of key based on the version of the software product that is installed. For example, if the 64-bit version is installed, this node opens a 64-bit key.
    KEY_WOW64_64KEY 8 This node opens a 64-bit key.
    KEY_WOW64_32KEY 9 This node opens a 32-bit key.

    Default: Default

    datatype_icon

    reference

    Reference to the open registry key.

    datatype_icon

    error out

    Error information.

    The node produces this output according to standard error behavior.
