This is my code for the serial port

BOOL CSerialCom::OpenPort(CString portname)
{
portname= "//./" +portname;

hComm = CreateFile(portname,
                      GENERIC_READ | GENERIC_WRITE,
                      0,
                      0,
                      OPEN_EXISTING,
                      0,
                      0);
	if(hComm==INVALID_HANDLE_VALUE)
	{
		MessageBox("Cannot open Communication Port.Please\nQuit the program and Re-start your PC.","Com Port Error",MB_OK+MB_ICONERROR);
		return false;
	}
		else
			return true;

}

Iam getting error

	error C2678: binary '+' : no operator found which takes a left-hand operand of type 'const char [5]' (or there is no acceptable conversion)

Does anyone has solution
