2) Write Operation
void CDemoForDSADlg::OnBtWrite() //Write operation
{
// TODO: Add your control notification handler code here
UpdateData(true);
if (m_strInstrAddr.IsEmpty())
{
MessageBox("Please connect to the instrument first!");
}
InstrWrite(m_strInstrAddr,m_strCommand);
m_strResult.Empty();
UpdateData(false);
}
3) Read Operation
void CDemoForDSADlg::OnBtRead() //Read operation
{
// TODO: Add your control notification handler code here
UpdateData(true);
InstrRead(m_strInstrAddr,&m_strResult);
UpdateData(false);
}
