To hide the form use the Form.Hide method. To show it again use Form.Show
Simple, no?

The property form.Visible determines whether a form is visible (shown).

you can put global bool var. and when you hide the form put it True else false
(it is just an idea)

this how i hide a form and open a new one

Form1 form = new Form1(); // new Form
this.Visible = false; // The Current Showing Form Hides
if(form.ShowDialog() == DialogResult.OK) // Makes Form Show 
{

}
this.Visible = true; / on close of the form you opened the one you started from shows

XML Serialization of ArrayList with derived objects [modified]

Dear Experts!

I am using xml in my project to store a list of objects of different types derived from the same base object.

[XmlArray("parts"), XmlArrayItem("part", typeof(Cpart))]
public ArrayList parts;		//Parts on page

This approach works only if all objects are of the same type.

Can it be dome with objects of different types in the array?

Thanks!

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#.

C# GUI build for UART FT232

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()

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