OK, here is the code snippet:
First, in you CustomControl we define an event:
namespace MyControlLibry
{
class MyControl : UserControl
{
public event MyControlEvent ModeChanged;
public MyControl()
{
}
// If user clicked on Insert button it cause trigger new ModeChanged event:
public ButtonInsertClick(object sender, System.EventArgs ea)
{
if (myevent != null)
ModeChanged(this, new MyCustomEventArgs("INSERT"));
}
}
// function prototype
public delgate void MyControlEventHandler(object sender, MyCustomEventArgs mcea);
// custom event args
public class MyCustomEventArgs: SystemEventArgs
{
private string stxt;
public MyCustomEventArgs(string text)
{
stxt = text;
}
public string MyCustomText
{
get { return stxt;}
set { stxt = value;}
}
}
}
Finally in you Form you must define event handler:
public class MyForm : Form
{
private MyControl ctrl;
public MyForm()
{
ctrl.ModeChanged = new MyControlEventHandler(CustomModeChanged);
}
// CustomModeChanged must have the same signature as delegate so
public void CustomModeChanged(object sender, MyCustomEventArgs mea)
{
Console.WriteLine(mea.MyCustomText);
}
}
Hope it helps

You have almost everything, but you have to add a couple of things:
1. You must provide definition for the MyCustomEventArgs (look at my previous exmple)
2. Define click event method for buttonNew button, and in this method call :
private void buttonNew_Click(object sender, System.EventArgs se)
{
if(NewRecord != null)
NewRecord(this, new MyCustomEventArgs());
}
3. According to me, it would be better to remove the delegate outside the class definition ( place it simply in dabir namespace )
4. Finally in your form where you are using your custom control register the appropriate method with similar signature as the delegate have.
//ArrowControl definition
ArrowControl ctrl = new ArrowControl();
//Form construktor
public MyForm()
{
ctrl.NewRecord += new MyControEventHandeler(NewRecordHandler);
}
public void NewRecordHandler(object sender, MyCustomEventArgs e)
{
// do appropriate things with new record 
}

Dear freind:
I add ur code to UserContol but it gives me error for not defined namespace.
These r my errors:
The type or namespace name 'MyContolEvent' could not be found<br />
The type or namespace name 'MyCustomEventArgs' could not be found<br />
The type or namespace name 'SystemEventArgs' could not be found
Please help me to figure it out!
Im looking to hear from u ASAP
Always,
Hovik.

OK, this is some typos
SystemEventArgs shoud be System.EventArgs ( sorry for that)
the declaration public event MyControlEvent ModeChanged; should be public event MyControlEventHandler ModeChanged;
Sorry, my fingers are quicker than my brain

Ive done that but with no delegate! maybe simpler way but I would like to share it if its good or not!?!
I made the buttoms declaration in UserControl as public & define a click event for them from from!

I wanted to try out using System.Management
but the compiler (I tried sharp-developer and Borland
c# builder) says that System.Management is undeclared.
What do I have to do, to make System.Management known?
Other namespaces, like System.IO, System.Net are available,
and I could compile and run programs using them.
I installed .NET 1.1 completely from the archive that
is about 100MB in size / os is Windows XP.
I found on the web, that XP should have WMI installed already.
Thanks !!

i am newbie in C#
thanks,
jim

well to call a base class as in java
Form1
super("My first form");
would be in c#
From1
base("my form"); // or whetever arguments are expected
if its a contructor
public Form1 () : base ("")
{}
I'm not an expert yet, but I play one at work. Yeah and here too.

I must be going mental or something because I can't for the life of me get one form to center on top of another. It seems to me that this code should work, but it doesn't.
this.Top = (this.Owner.Height / 2) - this.Height;
this.Left = (this.Owner.Width / 2) + this.Width; but it never centers the form. What am I doing wrong here?
- monrobot13

Your formula is wrong... Try this:
this.Top = (this.Owner.Height - this.Height) / 2;
this.Left = (this.Owner.Width - this.Width) / 2;
