The following is my code:
CNiExcelApplication _application(false);
CNiExcelWorkbook _workBook(_application.OpenWorkbook(path.GetBuffer())); // path是已经存在的一个excel文件
CNiExcelWorksheet _workSheet(_workBook.GetWorksheet(1));
CNiExcelCellRange range = _workSheet.GetRange("A1");
range.SetCellValue("Hello");
_workBook.save(path.GetBuffer(), CNiExcelWorkbook ::DefaultFileFormat); // line 10
There always pops up "class CNiExcelWorkbook saveas method is invalid".
But when I change line 10 by code line 11
_workBook.Close(CNiExcelWorkbook::SaveChanges); // line 11
Everything work correctly. I want to save the excel file but I don't want to close file while saving. Could anyone tell me what is wrong with my code ?
BTW, Is it possible to check if an excel file is already opened or not? (by double click, not by openworkbook method of CNiExcelApplication like above). If the excel file is already opened , is it possible to save file without closing the file?
