A while ago I wrote a program in Origin 7.5, which included the following part to import data from a ascii-file:
string strFile = GetOpenBox("*.*", NULL, "", "Bitte Datensatz auswählen");
if( strFile.IsEmpty() )
{
out_str("Bitte einen Datensatz auswählen!");
return;
}
Worksheet tabelleDaten("Daten"); // Erstellen der Daten-Tabelle
tabelleDaten.Create("Origin.OTW");
tabelleDaten.GetPage().Rename("Daten");
WorksheetPage PageDaten = Project.Pages();
PageDaten.Label = (fileName);
PageDaten.TitleShow = WIN_TITLE_SHOW_BOTH;
BOOL bRet = tabelleDaten.ImportASCII(strFile); // Kontrolle ob Datei importiert werden konnte
if( !bRet )
{
out_str("Datei konnte nicht importiert werden!");
tabelleDaten.Destroy(); // Wenn nicht -> zerstören der Tabelle
return;
}
So far, the highlited part worked fine to import the Ascii-files used by the people here, which almost allways have 1 or 2 Header-Lines and then consist of two columns of data. The tricky thing is, that as decimal-point some here use Points and some use Commas.
This never was a Problem with Origin 7.5, and Commas are still working fine, however, when I run this in Origin8, with a file that uses Points as Decimal-Point, I get completly messed up results.
When using the importwizzard directly from Origin all is working just fine.
I played around with ASCIMP a bit now, but I cant seem to find a setting or anything to fix this simple problem :/
Sorry about the bad readability, but I guess it helps understand the problem if I attach an example:
This is the File thats to be imported:

1,5E6 17233,33333
As you can see, the jump from "0.xx" to "1.xx" contains the problem in column 1, and I have absolutly no idea whats happening to column 2....
Thanks in advance and a nice day everyone

We have looked and found the reason 75 can handle such cases was purely accidental, not by design. We will need to add an Auto option for decimal separator to handle the situation you described, hopefully in the next SR (SR5).

Thank you for your answer. So, what could I do know?
I havent found an option to set decimal-separators at all.
Comma seems to work without any problems, but how can I set my import-function to import those files with points as decimal-separators correctly?
I know that its working in Origin, because the manual import does it correctly, I just dont know how to implement it in OriginC.
I read the entire OC_types.h, but while there is a lot about delimiters, there seems to be nothing about decimal-separators.
Thanks again ;)

The following Origin C code will show you how to import your two file types. The code is similar to what you posted but makes some important changes. The key part is the line setting the ai.nNumSep property. This property needs to be set according to the type of file you are importing. Also notice that the ImportASCII method returns an integer error code not a boolean as your code treated it.
void test_ascii_import()
{
string strFile = GetOpenBox("*.*", NULL, "", "Bitte Datensatz auswählen");
if( strFile.IsEmpty() )
{
out_str("Bitte einen Datensatz auswählen!");
return;
}
Worksheet tabelleDaten("Daten"); // Erstellen der Daten-Tabelle
tabelleDaten.Create("Origin.OTW");
tabelleDaten.GetPage().Rename("Daten");
WorksheetPage PageDaten = Project.Pages();
PageDaten.Label = (strFile);
PageDaten.TitleShow = WIN_TITLE_SHOW_BOTH;
ASCIMP ai;
if( AscImpReadFileStruct(strFile, &ai) == 0 )
ai.nNumSep = 1; // 1=American, 2=European
int err = tabelleDaten.ImportASCII(strFile, ai);
if( err )
{
printf("Datei konnte nicht importiert werden!\nError == %d\n", err);
tabelleDaten.Destroy();
}
}

Hello,
My previous post showed you how to use the ASCIMP nNumSep property to import your two file types. This post I want to show you how we can automate the setting of the nNumSep property by doing a simple test on the file before the import.
I wrote a new function named test_numeric_separator that will use the ReadFileLines function to read in the first 10 lines of a file. After reading the lines, the remaining code will count the periods and commas in those 10 lines. Based on the two counts the code decides if the file is American or European. This is of course a very crude test but will work for your files if they are indeed as simple as you described them. I have also included the previous function modified to call this new function.
I hope these functions and changes help you. If you have any questions about any of the code please do not hesitate to ask.
int test_numeric_separator(const char* pszFileName, int nNumTestLines = 10)
{
int nCommas = 0, nPeriods = 0;
StringArray saTestLines;
if( 0 == ReadFileLines(saTestLines, pszFileName, nNumTestLines) )
{
for( int nLine = 0; nLine < saTestLines.GetSize(); nLine++ )
{
nCommas += saTestLines[nLine].Count(',');
nPeriods += saTestLines[nLine].Count('.');
}
}
if( nCommas > nPeriods )
return NF_IS_EUROPEAN;
if( nCommas < nPeriods )
return NF_IS_AMERICAN;
return NF_IS_UNKNOWN; // can not determine file type
}
void test_ascii_import()
{
string strFile = GetOpenBox("*.*", NULL, "", "Bitte Datensatz auswählen");
if( strFile.IsEmpty() )
{
out_str("Bitte einen Datensatz auswählen!");
return;
}
Worksheet tabelleDaten("Daten"); // Erstellen der Daten-Tabelle
tabelleDaten.Create("Origin.OTW");
tabelleDaten.GetPage().Rename("Daten");
WorksheetPage PageDaten = Project.Pages();
PageDaten.Label = (strFile);
PageDaten.TitleShow = WIN_TITLE_SHOW_BOTH;
ASCIMP ai;
if( AscImpReadFileStruct(strFile, &ai) == 0 )
{
///ai.nNumSep = 1; // 1=American, 2=European
ai.nNumSep = test_numeric_separator(strFile);
}
int err = tabelleDaten.ImportASCII(strFile, ai);
if( err )
{
printf("Datei konnte nicht importiert werden!\nError == %d\n", err);
tabelleDaten.Destroy();
}
}

Awsome, thank you very much, that was exactly what I was looking for.
nNumSep was the missing property, I had seen it in the OC_types.h but didnt know if it was what I was looking for and if so, how to use it.
Maybe you could integrate this in the help-file?
But as long as the support here in the forum is so great, its fine with me the way it is ;)
Thanks a lot again.
