Hello,

I am new in Origin C. I try to assign some numerical values to a created worksheet.

Could somebody indicate why my little code (below) halts with
"general operation failure
general operation failure
general operation failure
general operation failure
Command Error!"

The code is

void InitializeWorksheet(string WorksheetName)
{
Worksheet wks(WorksheetName);

if(!wks)
{
out_str("There is no worksheet with the name "+WorksheetName);
return;
}

printf("Columns %d Rows %d \n",wks.GetNumCols(),wks.GetNumRows());


for(int nCol = 0; nCol < wks.GetNumCols()-1; nCol++)
{
Dataset Temp;
int Size=wks.GetNumRows();
Temp.SetSize(Size);
Temp.Attach(wks, nCol);

for(int nRow = 0; nRow < wks.GetNumRows()-1; nRow++)
{
printf("We are on the row %d\n",nRow);
Temp[nRow]=nRow;
}

}

Hi,

Runtime error here because when call Temp.SetSize(Size); Temp is an invalid object, should let Dataset attach to one column before SetSize. So change code to:

Temp.Attach(wks, nCol);
Temp.SetSize(Size);


BTW, I saw in for statement "int nCol=0; nCol < wks.GetNumCols()-1", this condition will NOT loop to the last column. If you want to loop to the last column, need change to nCol <= wks.GetNumCols() -1 or nCol < wks.GetNumCols()
