Working with vector values in C++ CLI - visual-c++

Question

Here is my header file in Visual C++ Express 2010 (note the last line):
/* custom class header to communicate with LynxMotion robot arm */
using namespace System;
using namespace System::IO::Ports;
public ref class LynxRobotArm
{
public:
LynxRobotArm();
~LynxRobotArm();
void connectToSerialPort(String^ portName, int baudRate);
void disconnectFromSerialPort();
void setCurrentPosition(int channel, int position);
int getCurrentPosition(int channel);
void moveToPosition(int channel, int position);
private:
void initConnection();
SerialPort^ serialPort;
array<String^> ^serialPortNames;
String^ portName;
int baudRate;
std::vector<int> *currentPosition;
};
I try to assign a value to the vector by using this function;
void LynxRobotArm::setCurrentPosition(int channel, int position)
{
currentPosition[channel] = position;
}
The compiler gives me an error C2679:
binary '=' : no operator found which takes a right-hand operand of type 'int' (or there is no acceptable conversion)
I looked up at MSDN and they say:
To use the operator, you must overload it for the specified type or define a conversion to a type for which the operator is defined.
I tried using currentPosition.at(channel) = position but it did not make a difference.
I am stuck... quite new to pointers, noted that using std::vector<int> currentPosition; instead of std::vector<int> *currentPosition; does not compile.
How should my set-function work? (will try getter afterwards..)
