Why isn't my new object being seen? C#
- by Dan
I am getting ready to take a class at a college on C#.  I have been reading up on it a lot and decided to start a fun project.  
Here is what my project consists of:  
Main Control Form 
Configuration Form
Arduino
Program.cs calls Configuration.cs at start.  This is where pin modes for the Arduino are set and where a timer is set.  When I set these values, they get sent to MainControl.cs.  When I hit the "Save" button in Configuration.cs, a MainControl.cs object is created [[I am correct in that?]]
All of those values that were sent by Configuration.cs had corresponding setters that set private static variables in MainControl.cs  [[ I don't really know if that is the preferred way, I am most definetly open to any suggestion anyone has]]
MainControl.cs uses its default constructor, and this constructor calls a method that creates an arduino object from one of the private variables (serialPort) [[ Using this Arduino class Firmata.NET  ]]  
When the arduino object is created, I know (I guess I do) because the form takes a few seconds to come up (As opposed to not using serial port)  My problem is this:
I do not understand why nothing can see the object
I have been very wordy, I apologize if I wasn't concise.  Here is the code:
public partial class CMainControl : Form
{
       private static string serialPort;
        public CMainControl()
    {
        InitializeComponent();
        createArduino();
        updateConfig();  // Change label values to values set in configuration
    }
    private void createArduino()
    {
        Arduino arduino = new Arduino(serialPort);
    }
In Configuration.cs, when I set the serial port through a combobox, the value is sent to MainControl.cs just fine.
Here is the error I get:
  Error    1   The name 'arduino' does not
  exist in the current
  context   C:\Programming\Visual
  Studio\Workhead Demo\Workhead
  Demo\CMainControl.cs  94  13  Workhead
  Demo
Please let me know if anyone can help and/or offer pointers, and please let me know if I didn't post or format anything correctly.
Thank you very much :)
