NI4060 MSVC++ and Auto Range. How?

Highlighted
I am trying to use the nidmm_32.dll library to perform some simple 2-wire
resistance measurements. I would like to turn on autoranging. I have tried
calling

niDMM_SetAttributeViReal64( vi, "", IVIDMM_ATTR_AUTO_RANGE_VALUE,
IVIDMM_VAL_AUTO_RANGE_ON )

but it still does not autorange. Does the niDMM api support autoranging or
do I need to write my own code to perform the same task?

Thanks,

BTW, at the moment, I am interested in 2-wire res. measurements.

Since natinst.public.* is the land of unanswered questions, I posed the
question to NI tech support. Setting the range to IVIDMM_VAL_AUTO_RANGE_ON
was the correct suggestion from NI.
