If .net frame work handles this...Y should I write destructors manually in some cases and

And how does this answer his question?

.NET does not have the same concept of destructors as C++ does. The ~T syntax (for C#) you see (where T is the name of the class) is actually a finalizer. You should almost never need to write a finalizer.
What you are probably thinking of is a Dispose method or the IDisposable interface. Really the only time you need to use this in your own class is when you are managing native resources (unmanaged memory) yourself or you are internally managing a class that implements it.
There are a lot of references available, both here on CP and the web. You can check out this article[^] for more information.

thanks in advance

To kalyan_2416,
Take a look at the following sample.
public abstract class BaseClass
{
public BaseClass()
{
Console.WriteLine("Invoke from base class.");
}
}
public class DerivedClass : BaseClass
{
public DerivedClass()
: base()
{
Console.WriteLine("Invoke from derived class.");
}
}
class Program
{
static void Main(string[] args)
{
new DerivedClass();
}
}
---------------------------output--------------------------
Invoke from base class.
Invoke from derived class.
---------------------------------

As I know, a real application has the ability to let users to change certain settings and alter the way the application runs, which is regarded as user configuration. Some settings will take the effect immediately after you click 'OK' while the program is running, some may request you to restart the program
I am a complete novice for programming, though I have read so many text books about C#. All I know now is that like how to create classes, structures, define functions, callbacks, delegates, interfaces, declare variables and so forth.
I totally have no idea about how to design a real application from scratch although I was thrown in this situation that I have to. I have partially completed the flowchart but I still don't understand how to persist and implement user configurations to make the application interactive?
Thanks for anyone could give me some hints.

As you mentioned, you're a newbie in C#, so I think the most important thing to you is not the application interative but how to create a real application.
You can create some applications without thinking too much more, just let them run with simple features, such as IO, Registry, Graphics, etc. These can help you with further programming.

Since then, you shoule know this way: you can use XML document to save the user configuration and let the application "read" the user's settings and "implement" them. Use XML to store and read user configruation. That's "what you do", not "how to do".

Thanks very much for your suggestion. But, if I could choose to start from all the fundamentals I would REALLY not put myself into this situation .

I did read about that the C# (or maybe the .NET framework) supports the *.resx file format which is to persist all the external resources used for an application. However, upon what I read I haven't figured out how to modify a resource file at real-time. And yes, the resource file is making use of the XML file. Is it what you were just trying to say?

.resx file is mostly like a file stores base 64 string of images or the extra infos of design mode of a form, and as default it's build as "Embedded Resource" in VS2005 (see the properties of one form, there is a "Build Action" node at the properties window). If you want to read and write the use configuration, a good way is to use .xml file or .config file, the select the "Build Action" as "Content", and the property "Copy to Output Direactory" as "Copy if newer".

Take a look at the System.Configuration namespece (mostly within the System.Configuration.dll assembly) as this contains everything you need to read and write configuration settings for an application.

I am interested in designing a custom Form skin. I have seen several articles in the Code Project concerning the use of the skin, but I haven't seen much concerning the tools and techniques to make a good skin. Thanks in advance for your help.

Use task manager to see if there is another copy of devenv running. Happens sometimes when exit from debugger is not clean.

The DEVelopment ENVironment - Visual Studio, or which ever IDE you are using.
Basically, something is keeping a previous instance of your application running. If you can't see it in taskmanager, download Process Explorer[^] from SysInternals (now Microsoft owned) and search for your module name. You can then kill it directly, or kill the task that is holding it open

Hi everyone, i would like to know if there's anyway I can detect a key pressed.
I know there exists the KeyDown and KeyPress events on every control, but i would like to know if theres any way I can detect these events in general, instead of checking these events on all the controls of my application.
I'm using a Parent Mdi Form containing lots of child forms, and of course this forms have lots of controls as well. I tried to apply this on the Parent Form's key events, but nothing.
I bet there's a simple way to get this done. Please help.
Thanks a lot for your time folks.

hi daniel,
for each form u have a property called kypreview, make this as true
and then add keypress or keydown event to that form,
so all the key press event come that function first and then goes to corresponding control
i hope this will solve ur problem
With Regards
Amjath
