I´m writing a C-program that collects data and presentate it in new file which i want to open in Excel
What do i write in my new file, so the data will be presentated in different sheets in the same worksheet
How do I make a new sheet?

I presume you are not talking C#.

Here is some code to add a sheet. Forgive the code if any problems, C++ is
not my language, but I am sure you will be able to correct any errors. The
new sheet goes before the selected sheet, but you can specify the Before
position.


// Convenient variables.
COleVariant
covTrue((short)TRUE),
covFalse((short)FALSE),
covOptional((long)DISP_E_PARAMNOTFOUND, VT_ERROR);

_Application oApp;
_Workbook oBook;
Workbooks oBooks;
_Workbook oHTML;

Sheets oSheets;
_Worksheet oSheet;
oApp.CreateDispatch("Excel.Application");

oApp.SetVisible(TRUE);
oBooks = oApp.GetWorkbooks();

oBook = oBooks.Add(covOptional);
oSheets = oBook.GetSheets();

// Now add a worksheet. If "before" and "after" are omitted,
// worksheet is
// added before all other worksheets.
oSheet = oSheets.Add(covOptional, covOptional, covOptional,
covOptional);
oSheet.SetName("MyNewSheetBefore");
