The check action signals all controls in a Window or Form part to check for user input errors based on the data type specified.

The destroyPart action destroys the part and its children, and releases all associated resources. You can use this action for both visual and nonvisual parts. All connections to the destroyed part are removed.

The showErrorToUser action automatically causes a message box to display to the user with the error message. When the user selects Ok on the message box, the original input is highlighted in the control with the first error found.
