PdhGetDoubleCounterValue (VB)
The Visual
Basic PdhGetDoubleCounterValue function returns the current value of the
specified counter as a double-precision floating point value. You should check CounterStatus
before using the returned number, because the counter may not be valid when it
is read. Call PdhIsGoodStatus to check the CounterStatus.

Parameters
CounterHandle
The ID of the
counter whose current value is to be read.
CounterStatus
The variable
in which the current status of the counter value is returned to the caller. The
returned data value is valid if and only if the value returned in CounterStatus
is PDH_CSTATUS_VALID_DATA or PDH_CSTATUS_NEW_DATA (defined in PDHDEFS.TXT).
If the value returned in CounterStatus is any other value, do not
use the data.
Return Values
PdhGetDoubleCounterValue returns the double-precision floating point value of
the current counter, computed and formatted as defined by the counter type.
