I have to disagree. Tier [Max] Support is talking to the programmer. When the problem is something that an literate monkey should be able to resolve with a script transferring the call back down is fully appropriate.

Programmers should not be allowed to talk to the "end user".

Strongly disagree.
0) to make sure what management says the customer wants and what the customer wants are the same thing.
1) If you never interact with the end users you'll never be able find out if how the user is using the app and how you intended the app to be used are one and the same.
2) Troubleshooting problems remotely is bad enough without filtering all data through layers of management.

I'm just being sarcastic at this point Dan. You gotta learn to recognize my mannerisms a little better.

That's damned false. Everyone here knows John started programming before opening his eyes.

Did you ask the same stupid question 10 times per day (and in the wrong place) when you couldn't program yet?
|
|
|
|

You would be surprised. Remember the bottom of the barrel charges the least and management thinks all programmers are the same.

I have the following code. when I run the code I have to one by one input fx,ft,apha,m,n. After I run the code:
Y
10
0.5
1
10
50
Code works with this way.
I writed to a file called "d:\\a.txt" this values(that is upper values).I tried to work the code by showing the file path but Code isn't works.

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.
Life goes very fast. Tomorrow, today is already yesterday.

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!!!
Panic, Chaos, Destruction.
My work here is done.

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...'
Panic, Chaos, Destruction.
My work here is done.
