You cannot use List without parameter, or you can use string array.
You forgot to set ok = true; in the input();
You have to replace \ with \\ in "name" (path) to make it working
never use anonymous try-catch block (means empty "catch {}" ). because of that you are not getting any error. so dont use that. always catch it with some message.

what isnt working? what does not happen that you expect it too? is your application crashing? are you getting any error messages? or any error messages that you have caught?
please explain your problem more, rather than posting alot of code and saying it does not do what you want it to.

I dont have any error message.
I want to run the code by showing file path d:\\a.txt insted of input each of values from screen.

You would if you actually caught your exceptions properly.
This code is wrong on so, so many levels. Firstly, try posting code that actually BUILDS before asking why it doesn't WORK! It does not work because it is SH!T.
Secondly, when you OPEN a stream it is considered good practice maybe even mandatory, to CLOSE THE FIN STREAM YOU MINDLESS TW@T!
Next let us look at variable names. Have you been programming in ZxSpectrum BASIC for the last 30 years? You can use descriptive cariable names you Muppet!
Structure? Heard that word before? Who puts an entire program into a constructor? Retarded MF's, that's who!
It took me about 30 sec to get this to work and output (as expected?) but then I have not been in a coma for the last eight years.
Now go away or I shall flame you!!!

I suffer from insomnia. Some nights I can't sleep at all and so lay awake all night.
As I lay there I listen to the soft elephantine breathing of my beloved, the hushed night time police sirens and I think to myself. I think about life, love, work, knowledge. All sorts of thing.
But most of all, I think "Why-oh-why can't someone, anyone, post a question in the codeproject programming forums about programming, rather then questions that show their ignorance."
This is normally followed by 'What would be a good flame for...'

JFC! I gave you the answer already; or at least told you how to advance.
1) Issolate the problem.
Find where it is going wrong and try to bebug it.
2) Your method input, which is crap, does not update the return value. Change the signature to:
private bool input(ref double fx,
ref double ft,
ref double alpha,
ref int n,
ref int m)
And call it somit like:
ok = input(ref fx,
ref ft,
ref alpha,
ref n,
ref m);
Don't change anything and compile. What do you see? Come on, you can do it! A few debug statements in the code and you'll soon see that the whole is method is a steaming puile of doo doo.
Personally, I would remove all the try/catch code and see what happens. then I would add try/catches where needed. This means you have to actually test your code for invalid input and/or data but it won't take long.

I know. I like to help, I really do. The problem is, well you know EXACTLY what the problem is.
So I've resolved to trying to prod them in the right direction. Using an electrified cattle stick. As the average intelligence comes out around duckweed, one has to derive what little pleasure is available.
In other news, it is now afternoon here and the Gin should be kickiing in around about now.

Dumbest mistake I've seen all day.
What happens when you use a function which is not a void?
The function has to return something eg:
private bool rawr()
{
bool returnObject = false;
...
return returnObject;
}
It's not rocket science it just common sense!
hmmm pie

Hi,
I'm trying to write a service that runs only in safe mode,
for that i need to figure out if I'm in safe mode or not,
how do i do that in c# ? (i cant use System.Windows.Forms.SystemInformation.BootMode since i'm in a service and no forms)
Thanks
Aviad.

I doubt that. Why would it be impossible to add a reference to ths System.Windows.Forms DLL and use the SystemInformation.BootMode enum? you don't need a GUI to do that. Have you tried it, what happened?

Hello! I am following this guide about switching background wallpaper via a windows service http://www.codeproject.com/KB/cs/C__Wallpaper_Switcher.aspx[^] but cant get it right.
My service is up and running (it do other things så of that I am certain) but the background wont just change. If I try exactly the same code in a win form app it works (and SystemParametersInfo returns 1) but not in my service (SystemParametersInfo returns 0). Has Vista something to do with it, security limitations? Is it posible to get better error messages from SystemParametersInfo?
