I'm trying to use std::ofstream to create a file but I'm getting an error. I'm using a string variable instead of a string. example below.
std::ofstream Myfile("C:\\testfile.html"); // This works fine
//but the below doesn't
string mystring = "C:\\testfile.html";
std::ofstream Myfile(mystring); //doesn't work. Not sure why.
Any clues?
std::string are different from C-style strings (null terminated sequences of characters).
For your example, use the .c_str() function from the string class to get the C-style string.
std::ofstream Myfile(mystring.c_str());

Read the error message. They usually give you really good clues as to what the problem is. If you're new to them, they can be a bit tricky to understand, so if you post it, we can walk you through it.
Also, it's helpful to us if you make it clear when your error is a compilation error, and when it compiles and runs and the error happens whilst running.
C++11 will accept a proper C++ string as the constructor parameter for an ofstream object; you might consider looking into updating your compiler so you can take advantage of C++11.
