What do you mean by that? How did it "jam" the debugger?

Simple. I caused it to crash

How can you expect help when you make vague statements like this. What were the manifestations of the crash? By "jam" it suggests that maybe it hung. You also mentioned you were unused to setting breakpoints. Perhaps you mistook the breakpoint hitting for a hanging application, because that is essentially what it does.

In deed I am unused with breakpoints, but I got that nice old error message, asking me if I want to send the error to microsoft..

Fair enough - but, if you'd said that to start with then we wouldn't have needed this exchange to determine that.

Hi!
First I would use a 'try-catch' just like:
try {
-your code-
} catch (Exception expt) {
System.Windows.Forms.MessageBox.Show(expt.ToString());
} // try-catch
The Next Point is that inline-code is easy to programm but hard to debug, so it's no good style to do everytrhing in a single line. So split your code:
string[] strArrayGot = Got.Split(":".ToCharArray(),2);
TO[num].Receive(strArrayGot[1]);
The next thing you have todo is watch your debugger. Then you can find out where the program exists.
I just talk about your variable names. But its hard to read. What the hell is TO and what about TOS? And listBox1 isn't a good name, too. What is handled there? The Number '1'?
Ok, you can programm that way, but it's hard to read and hard to find errors, so you should try to code a little bit more readable.
Hope I didn't dumbfounded you, was just an idea.
Greetings,
Ingo

Ok, there's no secret about it. TO is an array of forms, TOS is an array of integers. So when I try to open a new form, first i must know which form to try to open. It's part of a dumb mechanism. My problem is with num. I am SURE I am not trying to open the wrong form, but I want to ask you, could the rest of the function that calls TO[num].Show() be the problem? And by the way, my program is full of try-catch but you see, this error doesn't throw any exception, it displays a part of the form it should display and it stops working. Then I get that nice message about sending the report and I wonder if microsoft's coders want to help me solve the problem...

Ok sounds good.
So TO[num] is available and not null?! the string you give to receive(...) is ok?
Then I see the problem, if you thought to check this. The programm should work, but it doesn't. I got a similar error a few weeks ago.
The application crushed while calling a method of an object which was definitivly ok. The solution - sound strange - was to build the project new. I started with an empty projectmap, added empty projects, copied the forms and classes in the directory added each class and compiled again. After that the programm runned whithout any mistake (did I mentioned that I hate .Net?  ) !
Greetings,
Ingo

The solution to the problem remains illusive... please if anyone can help me... I wonder if the problem is that I am calling TO[num].Show() from
public void OnReceive(IAsyncResult ar), now is have to go...
|
|
|
|
|
I don't think so. Why should there be a problem. It's just an event. But you can find out. Don't show the form, start a timer instead, then from the timer-event you can show the form after e.g. 100 ms. If that works, you got the problem, if it doesn't work you know that this isn't the problem.

Ingo

Ok, I am finally home and I am going to try the timer thing...
|
|

Tried the timer, it simply doesn't trigger. Nothing hasppens. It is incredible.

You can't display a form from a threadpool thread (which I think OnReceive is). This[^] article tells you why it's a bad idea to do any UI manipulation from a non UI thread. For your problem, I'd suggest calling Invoke like this
delegate void FormShowDelegate(Form f);
public void OnReceive(IAsyncResult ar)
{
TO[num].Invoke(new FormShowDelegate(ShowForm), new object[]{TO[num]});
}
private void ShowForm(Form f)
{
f.Show();
}
This of course, assumes that you populated the TO[num] array from the UI thread..

Thank you verry much. I found out that the function runs in a new thread (or something like that) and to call a function in the main thread I would use invoke a few hours ago. Still, thank you very much, I'm so happy the program works now 
Cheers

I'm a bit of a tyro when it comes to .net, so I'm sorry if this question sounds very basic.
I want to create an EXE, which will offer a File Open dialog box. The user has to select a DLL which contains a class that implements a specific interface. I want to be able to create an instance of the class contained in the DLL and call some methods that it exposes, passing certain parameters and receiving return values.
How can I do this? I'd be grateful if anybody can kick me in the right direction.
Cheers,
Vikram.

Reflection is the way to go. You can use Assembly.Load[^] or one of its variations to get an Assembly object, then use the GetExportedTypes[^] method on that Assembly object to retrieve types in that assembly. You can then iterate over the types and use FindInterfaces[^] to check if that type implements the interface you want. Activator.CreateInstance[^] creates instances given the type and you should find it simple from there on.
Remember though, the assembly gets loaded in your AppDomain, so it won't get unloaded till your app (or your AppDomain) shuts down. So if some other process tries to write to that assembly, it will fail.

Thanks, Senthil. I'll look into your links.
Would you be interested in writing an article with me, on something that uses this? If you're interested, I'll explain what it's about.
Cheers,
Vikram.

To do this I try to use WebRequest command but I have an error when I called the page whith specifique control (security error). It's important for me to keep a trace of html contents. If you have another idea to do this tell me about it.
