I would search codeproject for examples of using Managed Extensibility Framework (MEF). I did a quick search and the latest versions should work under Mono. Try: http://www.codeproject.com/Articles/56635/Managed-Extensibility-Framework.aspx for a MEF intro. Going the MEF / roll your own solution route you can't avoid writing some OS specific code to start your "services" with the system but that shouldn't be too hard. Option 2: Check out http://linux.die.net/man/1/mono-service[^] which basically allows you to run .net windows services under mono/linux with little if any code change required. ~Justin_H

Has anyone figured out the problem atleast? has its name or any info about it? It would really help me alot, thanks.

check Codeplex www.codeplex.com

well excuse me for not having English as my native language and my day-to-day language ;-)

I would say you are looking for the Composite pattern: http://en.wikipedia.org/wiki/Composite_pattern[^]. With this pattern the quick solution is to make class A the composite and class B an component. A more beautiful solution is to create an abstract Component class that just contains the functionality related to administering the tree data structure. You then create 2 implementations of this abstract class: - class B that just re-uses the methods of the abstract class and adds its own functionality, - class A that just re-uses the methods of the abstract class, but adds collection functionality and its own functionality. A very beautiful solution is to separate specification from implementation: - specify B's own functionality in an interface IB, - specify A's own functionality in an interface IA, - make an abstract class Component that contains child logic, - make an abstract class Composite that contains collection logic, - make a class B that inherits class Component and implements IB, - make a class A that inherits class Composite and implements IA. In the implementation of class B, you can now check, if the parent is of type IA, and then use the functionality of IA. In the implementation of class A, you can now check, if a child is of type IB, and then use the functionality of IB. You can even make interfaces for the Component and the Composite, if you go 100%. Hope above was a little helpful. Remember, you decide your design! Regards, Keld Ølykke

My problem is that I can't serialize with binary formatter (even like you did, I can't), and SOAP doesn't let me serialize generic classes that I've made. I don't get what's hard to understand, I wrote it perfectly clear in the first message.

nevermind, I found the problem while debugging. It saved in the event B from some reason. I just added: [field: NonSerialized()] to every event. It works fine now. Thanks anyways :)

It sais "invalid modifier 'virtual' for C". I'll try Explaining again... I have these classes: public Class C { } public abstract Class A { protected C; } public Class D : C { } public Class B : A { private D; } When I do this: B = new B();, I have D AND C in B. And I need ONLY ONE, which is the newer one - D. How can I make the Class A use the new one (D) insted of the old one?

Thanks.... was looking for Add() function... (at start) :P

Try using the Enable property for each control i mean, on load form, the first controls group are enable and the second group disable, The validation control for the first group will be working meanwhile the validation control for second group arent, already the first validation, disable the all the controls for first group and enable the second, right now you can validate the second group. Try it, its just a suggest ;P keep Learning and you never will be out of date...

I added another question o_O

Not at all. I'm currently building a bot that ppl msg him an ip, and I wanna check if it exists, so they didn't fool it.

It will first add the control to the control collection of the page object, then it will write the text to the output stream. As the controls of the page is rendered to the output stream after the Page_Load (and Page_PreRender), the text will end up before the entire page, even before the <htlm> tag. If you want to put text on the page, put it in a control, either one that you put on the page in advance, or one that you add to the page. A Literal control is suitable to put plain text on a page. --- b { font-weight: normal; }

Thanks...

You can easily get the IP of the "surfer". From this IP you can get the location of the client. Try reading the link below.
