Hello,
I'm trying to use ATL support in a vc++ win32 project to retrieve rows of
data from a sql server database: Northwind. I would like to create 3 arrays
to store the ProductName, QuantityPerUnit, and UnitPrice so that I can use
them later in with the MatLab engine.
Currently, the ProductName is datatype 'TCHAR[41]', QuantityPerUnit
is'TCHAR[21]', and UnitPrice is 'CURRENCY'.
Where could I find the documentation to cast these datatypes into c++
datatypes?
Thank you,
Chieko
