Thank you Laurens, this is what I was thinking. So I started to adapt an existing QAction I formely develop to convert IEEE754 to double. But in this case, it looks like the QAction is never triggered. In short, I created table “1000”:

Added additional column as retrieved:

and added the corresponding parameter “1014”, decription “Es/No”.

QAction declaration with row=”true”:

Just to make sure it is triggered, I just assign a test value to parameter 1014 as follow:

protocol.SetParameter(1014,”6.91″);

In the table, the additional column appears indeed with title “Es/No”, however, the value under never appears and stays as “No Initialized”. In this particular case, I should see the value I assigned i.e. 6.91? Or I am missing something?

I could evenutally display my test value at the right place. So I know at least the QAction is triggered. But now I have some trouble to recover the string I need to convert in double. After various search in our installed driver, it came up to something like this to recover it:

string sKey = Convert.ToString(protocol.RowKey());
int iTrigger = protocol.GetTriggerParameter();

object oKeyVal = protocol.GetParameterIndexByKey(iTrigger, sKey, 2);
string s_raw_data = Convert.ToString(oKeyVal);

And 2 is the column index of the 1003 parameter I want to recover. However, it doesn’t seem to work …

Hi Laurens,

Indeed idx=”2″ so I set the GetParameter..; like this in it works:
object oKeyVal = protocol.GetParameterIndexByKey(iTrigger, sKey, 3);

So the issue is now fixed 🙂 Thank you very much for your help. Here below the complete code of the QAction which convert an “octectstring” representing a IEEE754 format number to double. I hope this can be useful for others:

public class QAction
{
///
/// Sets
///
/// Link with Skyline Dataminer
public static void Run(SLProtocol protocol)
{

string sKey = Convert.ToString(protocol.RowKey());
int iTrigger = protocol.GetTriggerParameter();
try
{

long raw_data = 0x0; // raw IEEE754 data
long s;
char c;
object oKeyVal = protocol.GetParameterIndexByKey(iTrigger, sKey, 3);
string s_raw_data = Convert.ToString(oKeyVal);

for (int i = 0; i = 0x30 && c <= 0x39)
{
raw_data <= 0x41 && c <= 0x46)
{
raw_data <> 24;
long n2 = (raw_data & 0xFF0000) >> 16;
long n1 = (raw_data & 0xFF00) >> 8;
long n0 = (raw_data & 0xFF);

double sign, exp, mantissa, value;

sign = Convert.ToDouble(-2 * ((n3 & 0x80) >> 7) + 1);
exp = Convert.ToDouble(((n3 & 0x7f) <> 7) – 127);
mantissa = Convert.ToDouble((0x800000 + ((n2 & 0x7f) << 16) + (n1 << 8) + n0)) / 0x800000;

value = sign * mantissa * Math.Pow(2, exp);

string s_data = Convert.ToString(value);

protocol.SetParameterIndexByKey(1000, protocol.RowKey(), 14, s_data);

}
catch (Exception ex)
{
protocol.Log(string.Format(NumberFormatInfo.InvariantInfo, "QA{0}: (Sets) {1}", protocol.QActionID, ex.ToString()), LogType.Error, LogLevel.NoLogging);
}
}
