IMVAutoCalcSetup

The IMVAutoCalcSetup interface contains methods and properties to configure the the auto calculation function from the MV Gauge filter. The results of the auto calculatons are send throught the I/O output pin from the filter.

Methods:

AutoCalcCount Count of possible auto calculations.
CalcLinesColor Colour for drawing results.
DrawCalcLines Draw auto calculation results.
EnableAutoCalc Enable an auto calculation.
GetAutoCalcParameter Get the parameter of a auto calulation.
GetAutoCalcResult Get auto calculation results.
IsAutoCalc Check if an auto calculation is enabled.
SetAutoCalcParameter Set the parameter of a auto calulation.

Method IMVAutoCalcSetup::EnableAutoCalc

Declaration: Sub EnableAutoCalc(Index As Long, Enable As Boolean)

Enable an auto calculation.

Parameter:

Index Index of the auto calculation (is equalant to the I/O output pin)
Enable Enable the auto calculation.
C Prototype:

HRESULT EnableAutoCalc(LONG Index, VARIANT_BOOL Enable);


Method IMVAutoCalcSetup::GetAutoCalcParameter

Declaration: Sub GetAutoCalcParameter(Index As Long, Enabled As Boolean, Algorithm As Long, Point1 As Long, Point2 As Long, Point3 As Long, Point4 As Long, Point5 As Long, Point6 As Long, Point7 As Long, Point8 As Long)
