Hi, I develop in VC++, I use boost library, I have a problem , I use Multi array It runs very well however I can't to include a boost array as a parameter in a function , the compilation is Ok but at the execution it does nothing. Too I can't declare a private member as boost multi array. With boost I can only return a boost multi array , that is OK . Declare member variabla as a boost multiarray it said extents unexpected for example: class Myclass { public : void maFonction(boost::multi_array<double, 2> res); private : int dim1; int dim2; typedef boost::multi_array<double, 2> boostResultatNearby(boost::extents[dim1][dim2][dim3]) } Can you help me please thanks --------------------------------- Nouveau : téléphonez moins cher avec Yahoo!
