as iam using Visual Studio 2013 i got an compile error which i can't solve. Here is the line of code

```
std::vector<std::pair<Vector2D*, Vector2D*>> m_joystickValues;

```

On MSDN they say following to this. <http://msdn.microsoft.com/en-us/library/t8xe60cf.aspx>

Now i dont really know how to change the code to work. As i see no mistake in writing this code above. Can you help me with clear answer?

The Compiler says:
