As i still dont have much programming exp., so there are some question of mine which want as answer.......
-> If i created a peice of code and its working, then i dont even think wheather it is good enough or not, i mean is there other better way?
So, how to analyse this?
(plz dont measure performance in neno-second(resources), as in small application it hardly matters)
-> How to analyse the worst case possibility of code?

if u r using a backend it really matters

Performance and properly architected code matter in all cases. Also, please use proper english and not SMS (Text) Speak in the forums and don't advertise.

This really depends on what you want to analyze. If you are just looking for performance measurements, you can do order analysis or wrap sections of the code in timing blocks. If you are looking for best practices type analysis, you can run tools like NDepend[^] or FxCop[^].
There are a lot of design resources available through CP, the web, or books as well that can give you good design patterns to start to follow.

Learn to spell 'should'
Pick out a small section of your code, a small class, or a few methods and post it here, asking people to critique it for you. Don't post your whole application though.
Whilst this is strictly a forum for answering problems regarding C#, considering the amount of dross that is being posted recently, I imagine you will get loads of people offering advice on how your code can be improved, and constructive criticism on what you have done.
If others don't agree with me, the worst you will get is a few '1' votes (and I'll get a few more for suggesting it!!)

Unless you're from NIIT - then you're on your own! (sorry, I have a problem with NIIT students on here at the moment - hopefully one of them will prove me wrong soon.)

I don't think that's likely to happen. They really do seem to like being the dross on the net.

I think that you need to learn to program and experience the mistakes. I learned programming with falling and standing up. Wrote brilliant code that later-on was a piece of crap caused by performance issues. Well this you learn while you are learning and doing.
How you can test if your application is doing fine, work with it.
Your application works fine with a small amount of data, what if you multiply this small amount of data by 1000?
Is my application slowing down? Do I make to much Interface call backs during the process?
Besides that, there are in the market profiling tools that can point out code that is taking to much time to run. Think of ANTS profiler and JetBrains.

I haven't looked too closely at your code but you'll receive a datareceived event as soon as the first byte comes in. Sounds like you're then trying to read everything that's arrived. Most of your data will still be yet to arrive.
Try reading a byte every time you get the datareceived event and then assembling them as you see fit.
This assumes you have set the serial port to send a datareceived event for every byte. If you've set it for more then read as many as you've set.

Dudes,
Why is it that everytime i download a csv file it will include the default.aspx
result:
11,22,33,44,55,test,testA,test12,8888,42352,asdf,as12DF,20000 ->this is only what i want
--> but it always include this
...
...
...
heres my code:
string filename = "default";
Response.Clear();
Response.ContentType = "APPLICATION/CSV";
Response.AddHeader("Content-Disposition", "Attachment; Filename =" + filename + ".csv");
Response.Flush();
Response.WriteFile(Server.MapPath("~/doc/default.csv"));
Did i miss something?
Thanks in advance,
C#Coudou

Hello All,
I have two tables First one has PK auto increment column and the second table Has FK I select the last inserted PK in the First table and insert it into the second table as FK. is there is any more professional way to do so or this is the correct way?

If you're using SQLServer you can get the value of @@identity. It's a sql server var that gives you the value of the last autoincrement assigned.

Hi
Should I write destructors for all the classes or do all classes have destructors by default(In built)

No, I don't think so.
.Net Framework has its own Garbage Collection.

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.

hi
how to call base class constructor from derived class
how to do it?
not by instantiaze the base class object..
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.
---------------------------------

You need to study and gain experience. Being the "top" in anything takes time and hard work.

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.
