I have done it in the following way:
1. registered the service: MyService.exe /service
2. added the associated type lib to the project:
using MyServiceLib;
(I used the Add reference wizard: Solution explorer tab, right click on the solution name, click on Add reference..., click on COM tab, in the appearing list box select the needed type library)
3. Created an object:
IMyObject newObject = new MyServiceLib.MyObjectClass();
4. Called the objects methods:
newObject.Function(param1, param2);

Hi there!
I've made a UserContol for my app. for modifing records in my form! SO i have new, delete & ... buttons in my UserControl but I wanna fire the AddRecord, DeleteRecord & ... functions from my Form! I mean functions are in my form but I want to fire them by clicking UserContol buttons.
How can I do this?!

Hello,
you can Add an custom events and delegates to your UserControl which will be trigged when user clicks button in your UserControl. In your Form you can register delegate method for the UserControl event which will be responsible for event processing.

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

Ok Tomas:
Third problem has gone but the rest still are breathing!!!
Please HELP?!?! What shoudl I do?!?!?

|
|
|

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 !!

hi, i overrided a method of the parent class. i want to invoke the overrided method in parent class. any keyword for this?
super? or what?
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.
