Your code is C++/CLI. So, you can use System::Object instead of boost::any.
And also, cliext::vector instead of std::vector. Because native class
(such as boost::any,
std::vector) can't have managed instance.

----
#include <cliext/vector>

Object^ val = dataGridView1[x,y]->Value;
String^ str = val->ToString();
cliext::vector<Object^>^ vec = gcnew cliext::vector<Object^>(n) ;
// or cliext::vector<String^>
(*vec)[x]=str;


------------------------------
Is it possible to convert a System::String to an std:string? With a conversion then i can use my boost classes...but i need to convert from std::string to System::String and vice versa....
I should use visual c++ only for interface input/output unless using visual classes....do you think i will have a lot of troubles? It's very difficult to find a good ide rad.... Thanks a lot!
