It seems I've put my:-> mouth in motion before putting my brain in gear! sorry...
In an App type this.Events you should see a RemoveHandler and this.Events[] gets you the list but I'll have to do more research on this subject.
Also I got to "Defining an Event" (sometimes repeating your steps at getting at a subject is harder than finding it in the first place)but if you look up EventHandlerList you will see the article in question.
Good luck

Maybe something like this should work:
public partial class myButton : Button
{
public myButton()
{
InitializeComponent();
}
public event ClickHandler Click1;
public delegate void ClickHandler(EventArgs e);
public myButton(IContainer container)
{
container.Add(this);
InitializeComponent();
}
protected override void OnClick(EventArgs e)
{
if (null != Click1)
Click1(e);
base.OnClick(e);
}
public bool HasListener
{
get { return (null != Click1); }
}
}

How to manage an event like OnClose, to do some actions before the moment some UserControl close.
I need to have a way to cancel Closing.
Thanx.
|
|
|
|
|
The cancel has to be done at the form level and you use the OnClosing and setting the e.Cancel property to true.
Good luck!

So, I handle OnClosing for a Form, and check all UserControls, belonging to the Form, for some state. If the state is not "right", I set e.Cancel to true.
Ok...
But how I can reach all UserControls belonging to the Form if I have nested containers like TabPages and Panels?

So, now that you failed your exam, after asking for help over and over, what have you learned for next time ?

Hopefully that open book exams are an order of magnitude more difficult that closed book exams in order to make up for the fact that reference material is permitted in the exam.

I'm afraid you're going to fail.
For starters, 3 hours before the exam is the wrong time to be learning. Secondly, even if I wanted to help, I don't know what sort of exam it is ? Is this high school ? An MS exam ? Some weird online thing ? I don't know, so I can't answer you, although the answer is, you've left it too late.

I though about form that have some timer (that auto close after some time) and hidden controls for minimize maximize, but is there some better way of doing this (and easier I guess)?

There's a splash screen component built in ( although I always just write my own )

Hi TrooperIronMan,
I once did it with a Splash class, basically a simple dialog window, showing some fixed text
(program name, version number) and a listbox reporting initialization progress. Two public
methods: ReportProgress(string) and Close().
The program's static main() method basically consisted of:
using (Splash splash=new Splash(...) ) {
splash.Show();
// check environment, license, whatever
splash.ReportProgress("Checking ...");
// check for singleton
splash.ReportProgress("Checking for another instance");
Form1 form=new Form1(splash);
splash.Close();
Application.Run(form);
}
Main reason for using the splash was when not first instance, main would send command line
to first instance, using remoting; firewall (ZoneAlarm) sometimes needs 30 seconds to provide
the dialog "Application has changed; allow access ?", so the user was left in the dark.
I even added a /noserver switch to skip the remoting stuff while debugging (ZoneAlarm
notices the EXE keeps changing, so asks over and over).
Cheers

Hello there,
I am developing an online board game using C#. For the starting, the project has 3 different sub projects:
Server , Client , Authenticator. Client connects authenticator and gets authenticated then, authenticator passes to client the filled account object. To do that i have to give reference to Authenticator from client. The problem here is Client wont run without Authenticator.exe on client side which i dont want to let people have the authenticator class.
In other words, i need a solution that Client will have only one application file and the rest will be on remote side.
Anyone can redirect me to a related article or give some advices here?
thanks in advance..

At three hours before the exam, don't you think it is getting a bit late to start studying for it?

These kids, today! I remember when we didn't even have the Internet, and we had to plead with our roommates to take our open book exams.

I an writing a Software Automation Human Machine Inteface application in C#. Porting over form Visual basic 6 code. In the VB6 version we used CreateObject("ClassName", "MachineName") to instantiate a class for communicating with the ProcessControl Server. This is not an imperative change but I was wandering if there is a way to do this in C#.
Applicator.CreateInstance doesn't work. Or would it be better to just stick with the vb interop version of the Comms Class?
Thanks in Advance.

To interact with a COM object, you import it into your project, and you'll be able to create instances just a if it was a normal class.
