ViRsrc matches=buffer;
ViUInt32 nmatches;
ViFindList list;
viOpenDefaultRM (&defaultRM);
// acquire the USB source of visa
viFindRsrc(defaultRM, "USB?*", &list,&nmatches, matches);
viOpen (defaultRM,matches,VI_NULL,VI_NULL,&vi);
viPrintf (vi, "*RST\n");
// send the command received
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 result
UpdateData (TRUE);
