XLL+ Class Library (7.0)


Assigns a 1-dimensional array of numbers, booleans or strings to the CXlOper

template< class T >
const CXlOper& FromVector2(
   const std::vector<T>& dvec,
   bool bRow = FALSE,
   size_t lLBound = 0,
   bool toBoolean = FALSE



1-dimensional array of data.

The following types for T are directly supported:

  • bool
  • long
  • unsigned long
  • int
  • unsigned int
  • short
  • unsigned short
  • double
  • float
  • CString
  • CStringA
  • CStringW
  • std::string
  • std::wstring
Any other type is treated as an enumerated type, and converted first to long and then to a number.


If true, then the vector created will be a row; otherwise the vector will be a column.


The lower bound of "interesting" inputs. The first lLBound items in the input vector will be ignored.


If true, then the resulting Excel array will contain boolean values instead of numbers. (If T is a string, then all values will be false.)


This function sets the type of the CXlOper to be an array with a single column or row, allocates space for the vector of doubles, booleans or strings provided and sets the values into the CXlOper.

This function is called by the CXlOper(std::vector<...> vec) constructors.

Note that integer numeric types are returned to Excel as boolean values. To return integer types as numbers, use CXlOper::FromNumericVector2().

The method will throw an exception of type CXlEmptyArrayException if the supplied array is empty, or of type CXlArrayTooLargeException if the array is too large.
