Hi,
I have a little Problem with typing my Dataset.
In the Manual to the Programming guide is written, that it is possible to type a dataset to char.
The Progromming Guide is also able to compile an link it, but if I try to call this function followed message is plotted:

Warnung, Argumentfehler Datentyp
Laufzeitfehler in Origin C Funktion, allgemeiner Ausführungsfehler

i trie to translate it in english

warning argument failure in datatype
runtime error in origing c function, general ...failure

the code I compile is:

void test_schleife_File()
{
Worksheet wkstfa;
wkstfa.Create("0");
wkstfa.SetNumRows(500);
wkstfa.AddCol("File");
wkstfa.AddCol("Date");
wkstfa.AddCol("Time");
wkstfa.AddCol("Blq1");
wkstfa.AddCol("Blq2");
wkstfa.Columns(0).SetType(OKDATAOBJ_DESIGNATION_NONE);
wkstfa.Columns(1).SetType(OKDATAOBJ_DESIGNATION_NONE);
wkstfa.Columns(2).SetType(OKDATAOBJ_DESIGNATION_NONE);
wkstfa.Columns(3).SetType(OKDATAOBJ_DESIGNATION_NONE);
wkstfa.Columns(4).SetType(OKDATAOBJ_DESIGNATION_NONE);
wkstfa.Columns(0).SetFormat(OKCOLTYPE_TEXT_NUMERIC);
wkstfa.Columns(1).SetFormat(OKCOLTYPE_TEXT_NUMERIC);
wkstfa.Columns(2).SetFormat(OKCOLTYPE_TEXT_NUMERIC);
wkstfa.Columns(3).SetFormat(OKCOLTYPE_TEXT_NUMERIC);
wkstfa.Columns(4).SetFormat(OKCOLTYPE_TEXT_NUMERIC);
Dataset<char> dsFile(wkstfa, 0);
Dataset dsDate(wkstfa, 1);
Dataset dsTime(wkstfa, 2);
Dataset dsBlq1(wkstfa, 3);
Dataset dsBlq2(wkstfa, 4);
dsFile.SetSize(500);
dsDate.SetSize(500);
dsTime.SetSize(500);
dsBlq1.SetSize(500);
dsBlq2.SetSize(500);
}

I hope someone can help me!!

Hi 5*10,

In order to write and read strings to/from a dataset column, you need to use a vector of type string and then use PutStringArray and GetStringArray methods.

For example:


	Dataset dsFile(wks, 0);
	StringArray sa(4);
	// The above is same as vector<string> sa(4);
	
	sa[0] = "File1";
	sa[1] = "File2";
	sa[2] = "File3";
	sa[3] = "File4";
	
	dsFile.PutStringArray(sa);
