How do I truncate a float such that if i have 1.20001, i would want to have 1.2 only for display. How could I achieve this? Thank you very much!

If you just want the truncated value as a string, you can use the ToString method on the float instance, like
float f = 1.2001f;
string truncatedFloat = f.ToString("0.0");
If you want that value as a float, you could multiply it by 10x, where x is the number of digits of precision required, cast it to an int and divide by 10x again i.e 1.20001 * 10 = 12.0001 = 12 / 10 = 1.2

Note that this is not guaranteed to produce the exact value that you expect. A float only has a precision of seven digits, so the result may just as well be something like 1.19999 or 1.20001.
And why not use Math.Round(f, 1)?

Agreed, I missed the fact that the floating point representation could screw up things. But if he already uses tolerance values when checking for equality among floats, this shouldn't matter, right?

Two group of cards (one with 10 cards , another with 5 cards), what I want is to discard one card out of 10 cards from one group and it become 9 cards. Then I choose one of the cards from another group with 5 cards by clicking the card. After I choose it , I want to be added that card in the group with 10 cards again! How can it be work?

You are a bit vague...,
for instance, which data structure did you use?, some sample code?

Well, the first step when you're assigned homework, is to try to do it. That's what it's for. The process of trying, and perhaps failing, is how you learn. You learn nothing if I were to write this code for you.
One you've tried to do your own homework, if you're stuck, post it here, and we're happy to offer advice. I certainly lean towards hints rather than writing the code for you. Otherwise, when I'm a manager, all the people I'm managing will be totally useless, as they've never had to solve a problem for themselves.

Hey guys,
i have site online where my registered users can upload their files. I want to make a desktop application that lets my users upload their files from the application itself. I will be uploading my files using the regular HTTP upload. DO you have any information on where I could get started. I have never made something like this.

hey,
I did a bit research online and found that I'd have to first do an HTTP POST and authenticate myself and then save the logon information as a cookie. Once that is done, I'd have transmit the file in chunks. Is that right? Is there another way? Would I have to do all my HTTP POST and GET through the System.Net.WebClient namespace?

In my game, if one player put one card , another player have to put one card that is greater in sequeue than the first one (3>2) so how can I set those order with sort of cards? Those are no number , that's why!
|

Depends entirely on how you define your cards. Without any code we cannot answer your question.
My suggestion would be to create an enumeration of card values, something like this:
public enum CardValue
{
cv2 = 2,
cv3,
cv4,
cv10,
cvJack,
cvQueen,
cvKing,
cvAce,
}The enum is based on int by default, so (int)CardValue.cvJack will yield 11, for example and CardValue.cvKing > CardValue.cvQueen will return true.

Stop spamming the forum. You only have to ask that question once.
