Origin Version (Select Help-->About Origin): 7.5 Pro
Operating System: Windows 2000
Hi,
I want to include header lines in exported data. The values of the header lines are stored in the system variables page.user.info.L1V1$...page.user.info.LNV1$, depending on the number of header lines. What i want, is that these strings are stored first in the export file, before the data are stored there.
How could I do this?
Thanks, Kai |

Hi Kai,
Use the Origin C function at the bottom like this...
ExportWksWithHeader 5 C:\Data\data.dat;
The first argument is the number of lines you want to save to header. The second argument is the file name. Omitting the second argument will bring up a file dialog.#Function starts here
void ExportWksWithHeader(int nLines, string strFile = "")
{
Worksheet wks = Project.ActiveLayer();
if( !wks )
return; // wks must be active
if( strFile.IsEmpty() )
{
strFile = GetSaveAsBox("*.dat");
if( strFile.IsEmpty() )
return; // user cancelled file dialog
}
string str;
WorksheetPage wpg = wks.GetPage();
stdioFile f1(strFile, file::modeCreate | file::modeWrite);
for(int i=1; i<=nLines; i++)
{
if( !page_get_info_var_value(wpg, "L" + i + "V1", str, "user.variables") )
break;
f1.WriteString("#" + str);
}
f1.WriteString("#Data"); // identify start of data ??
char szTemp[MAXFULLPATH];
GetTempPath(MAXFULLPATH, szTemp);
string strTemp = szTemp + "temp.dat";
if( wks.ExportASCII(strTemp, WKS_EXPORT_ALL)<0 )
return;
stdioFile f2(strTemp, file::modeRead);
while( f2.ReadString(str) )
f1.WriteString(str);
}

Hi Mike,
thanks a lot, that was a good starting point.
I extended the script, so that the column labels / titles are written before the header lines, and a dialogbox asks for the export options,
so if anybody needs this...

#include <Origin.h>
#include <GetNBox.h>
void ExportWksWithHeader(string defaultfilename)
