How to deny access to a configuration file

[JB]

The Deny Access function returns an error 1 when wiring the refnum from a configuration file. The LV help only mentions that you cannot deny access to a datalog file. Am I missing something obvious ?

JB,

Try closing the file first.

Configuration file references are created and tracked by the Config Data Registry VI (in C:\Program Files\National Instruments\LabVIEW 8.6\vi.lib\Utility\config.llb).  You'll notice that the confuration file reference number (e.g. 2) doens't match the file reference number ( e.g. 445644800).  This is why the "To More Generic Class" node doesn't accept the Configuration File Reference Constant.
