You can fill combo box like this

comboBox1.DataSource = Enum.GetNames(typeof(System.Windows.Forms.Keys));

From the subclassing point of view, use the sealed keyword.

If you talking about declaring a final instance variable in Java, use the const or readonly keyword in C#.

Me, I'm dishonest. And a dishonest man you can always trust to be dishonest.

I am building a GUI for a UART to communicate to a MC and then to a I/O expander. Right now I have the data going thru the RTS and DTS and my switches monitored by CTS DSR DCD and RI. How could I change this to be implemented to use only TX and RX for all of this without having to start all over. I am not real great with programming but I do know enough to understand. I have included the piece of code that I use for this part.

     #region Initialization
        public enum LEDColor { RedOn, RedOff, GreenOn, GreenOff }

        private bool RTSState = false;
        private bool DTRState = false;
        private bool RingIndicator = false;

        public Form1()
        {
            InitializeComponent();

            pictureBoxRTS.BackgroundImage = imageList1.Images[(int)LEDColor.RedOff];
            pictureBoxDTR.BackgroundImage = imageList1.Images[(int)LEDColor.RedOff];
            pictureBoxCTS.BackgroundImage = imageList1.Images[(int)LEDColor.RedOff];
            pictureBoxDSR.BackgroundImage = imageList1.Images[(int)LEDColor.RedOff];
            pictureBoxDCD.BackgroundImage = imageList1.Images[(int)LEDColor.RedOff];
            pictureBoxRI.BackgroundImage = imageList1.Images[(int)LEDColor.RedOff];
        }
        #endregion


        #region Modem lines
        // Show the modem states on the virtual LEDs
        private void serialPort1_PinChanged(object sender, System.IO.Ports.SerialPinChangedEventArgs e)
        {
            // Toggle RI since we can't determine the state with the SerialPort class
            if (e.EventType == SerialPinChange.Ring) RingIndicator = !RingIndicator;

            showCTS_DSR_CD();
        }

        private void showCTS_DSR_CD()
        {
            if (serialPort1.IsOpen)
            {

                else this.pictureBoxCTS.BackgroundImage = this.imageList1.Images[(int)LEDColor.RedOn];

                else this.pictureBoxRI.BackgroundImage = this.imageList1.Images[(int)LEDColor.RedOn];
            }
            else MessageBox.Show("Error in showCTS_DSR_CD - serailPort1 not open.");
        }

How can I convert 
ResXResourceReader rsxr = new ResXResourceReader(@"C:\Resource1.resx");

TO

ComponentResourceManager res = new ComponentResourceManager(typeof(Properties.Resources));

I mean How can i reference res with rsxr :

res = rsxr;

If it didn't help you, then I have to assume you didn't read it. It certainly gave me enough pointers to start working with dynamic resource files, if I actually wanted to - which I don't.
What do you want - your hand held while we tell you "press the 'A' key, now the 'r', then 's'..."?

no dear!

I have written a multiple language
And i have used resource for each form!
Then i wanna to give my customer this choose to change the resource Values for exm.Label.Text so how can i do that?

when i complied my project there wasnt any .resx file!

Then RTFM! The links provided even link to a tutorial:

MSDN wrote:
The Microsoft .NET Framework SDK provides several samples that illustrate how to work with .resource files. See Resources and Localization Using the .NET Framework SDK Tutorial, the ASP.NET QuickStart Localization sample, and the Common Tasks QuickStart How To: Resources.

How hard can it be?
Given the quality and nature of your questions over the last month or so, I really feel sorry for your customer! He actually has to pay for something you clearly have no idea how to do!
