Hi, I am struggling to find the proper combination of ataptors/binders to use a member pointer to a member function in a for_each. Is this possible at all? Any help is appreciated. Here is the code: #include <iostream> #include <algorithm> #include <vector> #include #include using namespace std; class foo { private: int value; void default_proc(int& x) { cout << "default_proc. Value = " << value << ", Param = " << x << "\n";} void init1_proc(int& x) { cout << "init1_proc. Value = " << value << ", Param = " << x << "\n";} public: void (foo::*func_ptr)(int& x); //yes, I need the reference here foo(int init) : value(init), func_ptr(init == 1 ? &foo::init1_proc : &foo::default_proc) {} }; int main() { vector<foo> foos; foos.push_back(foo(0)); foos.push_back(foo(1)); foos.push_back(foo(2)); int param = 3; //i need this functionality: //prints "default_proc. Value = 0, Param = 3": (foos[0].*foos[0].func_ptr)(param); //prints "init1_proc. Value = 1, Param = 3": (foos[1].*foos[1].func_ptr)(param); //prints "default_proc. Value = 2, Param = 3": (foos[2].*foos[2].func_ptr)(param); //using the right combination of for_each, bind, ref, mem_fn, etc: // std::for_each(foos.begin(), foos.end(), // boost::bind(???????), // _1, boost::ref(param)); } The compiler is Borland C++ 5.6.4 for Win32. Thanks in advance
