Excuse me, I' m reading a DataGridView with VisualC++2008 with nested loops.... ..... Object^ val=dataGridView1[x,y]->Value; //Object is a Visual class ..... I convert every value in a System::String variable: String^ str=val->ToString();

Then I'have to insert this data in a container (for example) this: vector<boost::any>* vec=new vector<boost::any>(n) ; //0<=x<n (*vec)[x]=str; //ERROR! (*vec)[x]=*str; //ERROR!

Is there another method to transfer a value from a dataGridView to an STL container? Now i wrote only a vector to explain simply but in fact i will use a table of this type vector<vector<boost:.any>*>.

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....
