Transform one row or column of a CXlOper into a vector of an extended type
template< class T, class XLT > void XlReadGroupedVectorEx( const CXlOper& xlo, std::vector<T>& value, const CXlUserConverterBase<T, XLT>& outerConverter, const wchar_t* groupName, unsigned long rowOrColumn, const wchar_t* argName, unsigned long flags = 0, long* expectedSize = NULL, unsigned long lowerBound = 0, const T& defaultCellValue = T() );
A reference to the input passed by Excel.
A reference to a variable into which the results will placed, if the conversion is successful.
An instance of the extended type's converter class. See CXlUserConverterBase for details.
The name of the Excel argument that contains the vector group. This will be used in error messages.
The index of the item within the group. Depending on the orientation of the vector group, this may be a row index or a column index.
The name of the item within the group that is being converted. This will be used in error messages, and may also be used to search the grouped input.
A set of flags that control the conversion. See Conversion functions for a list of values.
A pointer to variable that will receive the size of the vector. If it has already been set (i.e. does not have a value of -1), and the size of the vector is not equal to the value. then an exception of type CXlConversionException will be thrown, along with a user-friendly message, such as "Expected 15 items in X". If the pointer is NULL, then the argument will be ignored.
The number of empty items to insert at the start of the result vector. If you are going to pass the vector to a library function that expects vectors to be 1-based, then this value should be set to 1.
The default value that will be used for empty cells, if the appropriate flags have been set for the conversion.
If the function fails for any reason, an exception of type CXlConversionException is thrown. This will be caught by the outer wrapper function, and converted into an appropriate form to be returned to Excel.
