hey OriginalGriff,
Tks for the reply. i have edited my question to make it more clear.
I open and hide my form using form.show and form.hide
how do i check if the current form is hidden so as not to perform certain task
|
|
|
|
|
The property form.Visible determines whether a form is visible (shown).Greetings - Jacek

|
|
|
|
Great. It works. tks Jacek
|
|
|
|
|
you can put global bool var. and when you hide the form put it True else false
(it is just an idea)
|
|
|
|
|
Tks. alternative idea for visible method.
|
|
|
|
|
this how i hide a form and open a new one
Form1 form = new Form1();
this.Visible = false;
if(form.ShowDialog() == DialogResult.OK)
{
}
this.Visible = true; / on close of the form you opened the one you started from shows

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;
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!modified on Tuesday, February 9, 2010 4:43 AM

You can fill combo box like this
comboBox1.DataSource = Enum.GetNames(typeof(System.Windows.Forms.Keys));-----------------------------

Hi,
What's the equivalent of final keyword(Java) in C# ?
Thanks.
|
|
|
|
|
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. Honestly. It's the honest ones you want to watch out for...

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
private void serialPort1_PinChanged(object sender, System.IO.Ports.SerialPinChangedEventArgs e)
{
if (e.EventType == SerialPinChange.Ring) RingIndicator = !RingIndicator;
showCTS_DSR_CD();
}
private void showCTS_DSR_CD()
{
if (serialPort1.IsOpen)
{
if (serialPort1.CtsHolding) this.pictureBoxCTS.BackgroundImage = this.imageList1.Images[(int)LEDColor.GreenOn];
else this.pictureBoxCTS.BackgroundImage = this.imageList1.Images[(int)LEDColor.RedOn];
if (serialPort1.DsrHolding) this.pictureBoxDSR.BackgroundImage = this.imageList1.Images[(int)LEDColor.GreenOn];
else this.pictureBoxDSR.BackgroundImage = this.imageList1.Images[(int)LEDColor.RedOn];
