Closes a refnum associated with an open VI, VI object, an open application instance, or a .NET or ActiveX object. Details
|reference is the refnum associated with an open VI, VI object, an open application instance, or a .NET or ActiveX object.|
|error in describes error conditions that occur before this VI or function runs.
The default is no error. If an error occurred before this VI or function runs, the VI or function passes the error in value to error out. This VI or function runs normally even if an error occurred before this VI or function runs. If an error occurs while this VI or function runs, it runs normally and sets its own error status in error out. Use the Simple Error Handler or General Error Handler VIs to display the description of the error code. Use error in and error out to check errors and to specify execution order by wiring error out from one node to error in of the next node.
|error out contains error information. If error in indicates that an error occurred before this VI or function ran, error out contains the same error information. Otherwise, it describes the error status that this VI or function produces.
Right-click the error out front panel indicator and select Explain Error from the shortcut menu for more information about the error.
When you create a refnum to a VI, LabVIEW loads the VI into memory. The VI stays in memory until you close the refnum and until the VI meets the following conditions:
