ViChar buffer [VI_FIND_BUFLEN];

ViRsrc matches=buffer;

ViUInt32 nmatches;

ViFindList list;

viOpenDefaultRM (&defaultRM);

// acquire USB resource of visa

viFindRsrc(defaultRM, "USB?*", &list,&nmatches, matches);

viOpen (defaultRM,matches,VI_NULL,VI_NULL,&vi);

// send the receiving commands

m_combox.GetLBText(m_combox.GetCurSel(),strTemp);

strTemp = strTemp + "\n";

stringTemp = (char *)(LPCTSTR)strTemp;

viPrintf (vi,stringTemp);

// read the result

viScanf (vi, "%t\n", &buf);

// display the results

UpdateData (TRUE);

m_receive = buf;

UpdateData (FALSE);

viClose (vi);

viClose (defaultRM);
