Hi!
Im using Origin 9 SR2.
I'm programming origin C and I really do not want to use the other origin programming languages.
So here are my questions:
1) Is there a way to get the index of the last number in a row? With several functions like importing, rows after the last number are filled with "--". I want to avoid these and just get the index of the last real number. So I tried GetSize(), GetUpperBound(),NumRows(), but nothing yields this. Is there a way?
2) The user of my script has used the masking tool to mask some data in a plot. I now want to calculate something from the column with the masked values, but the masked values are ignored. Is there a possibility to acess data in a column while ignoring masking? Or if this is more simple: is it possible to remove the masking from a column?
3) Is there a possibility to change what is written in the "set column values" menu, rather than calculating the values of a column by software and then just inserting it there? It would be nice if my user could alter the formula for the calculation afterwards ...
Thanks in advance!
Nikolas

Here is an example that removes all masked values from a column and also returns the last value in the column.
double sample1(string strWks, uint iCol)
{
Worksheet wks(strWks);
Dataset ds(wks, iCol); // iCol indexed from 0
uint iSize = ds.GetSize();
// Remove mask from column range
DataRange dr;
dr.Add(wks,iCol,"junk");
dr.SetMask(0); // 1 would set as masked
// Get the last value
return ds[iSize - 1];
}
Your user can select the column with the formula and press Ctrl+Q to open the Set Values dialog and change the formula. 9.1 users have the option of showing the F(x)= header row and you can edit the formula right there.

Hey greg,
thank you very much!
What I meant with my last question is: can I give the formula of a row via Origin C? Is there a possibility to change via OriginC, what the user can edit by pressing ctrl+Q?
Right now, I calculate values and just insert them in the column, after that, the formula is lost, if the user opens the Set Values dialog, it's empty.
Is there a way to write there via Origin C?
Best regards,
Nikolas |

We have a csetvalue X-Function which lets you programmaticaly do what Set Values does.
Here is an example:
#include <XFbase.h>
int sample_set_values(string strWks, int iCol, string strFormula, string strScript)
{
// Create an 'XF' object
XFBase xfSCV("csetvalue");
if( !xfSCV.IsValid() )
{
out_str("Failed to load csetvalue X-Function.\n");
return -1;
}
Worksheet wks(strWks);
if( !wks.IsValid() )
{
out_str("Failed to attache to worksheet\n");
return -7;
}
Range ra;
ra.Add("Range1", wks, 0, iCol, -1, iCol); // A whole col (column C)
// csetvalue has four arguments which need to be set
if( !xfSCV.SetArg("col",ra) )
{
out_str("Failed to set range.\n");
return -2;
}
if( !xfSCV.SetArg("formula", strFormula) )
{
out_str("Failed to set formula.\n");
return -3;
}
if( !xfSCV.SetArg("script", strScript) )
{
out_str("Failed to set script.\n");
return -4;
}
if( !xfSCV.SetArg("recalculate", 0) )
{
out_str("Failed to set recalculate.\n");
return -5;
}
if( !xfSCV.Evaluate() )
{
out_str("Failed to evaluate the setvalue X-Function.\n");
return -6;
}
return 0;
}
Note that even though the XF called from LabTalk interprets columns indexed from 1, in the C environment column indexing is from 0. Also, called this way, recalculate is disregarded, but your user will be able to open Set Column Values and see/change what you put there.
e.g.
val = sample_set_values("[Book1]Sheet1",0,"100 * ds","dataset ds;ds = data(1,00);");
