2 From the PAWS Project window, select the ctrl.cpp file. Insert the following
code in the ctrl.cpp file directly below #include "key.h" code:
#include "DMM.h"
extern CComPtr<IAgilent34401> driver;
extern CComPtr<IAgilent34401DCVoltage> pDMMDCVolt;
extern CComPtr<IAgilent34401Trigger> pDMMTrig;
extern CComPtr<IAgilent34401Measurement> pDMMData;
extern HRESULT hr;
3 From the PAWS Project window, select the DMM.cpp file. Insert the following
code in the DMM.cpp file directly below #include "key.h" code:
#include "DMM.h"
CComPtr<IAgilent34401> driver;
CComPtr<IAgilent34401DCVoltage> pDMMDCVolt;
CComPtr<IAgilent34401Trigger> pDMMTrig;
CComPtr<IAgilent34401Measurement> pDMMData;
HRESULT hr;
4 To create the driver object and open an I/O session to the instrument with the
