Algorithm problem! -

Hi!

I guess im REALLLLY tired at the minute and will think this through tomorrow but its something that isnt going to make me go to bed easily!

OK:

I have a start time and end time
a user also enters a start time and end time

I want to see that if the user's entered start time and time conflicts with the set start time and end time.

how do I find this out?

I will have 2 DateTime objects for each date time set. One object will be the start time and the other the end time.

so i wanna check if the user entered their start/end time does NOT conflict with another start/end time.

how?

 

Best Encription Algorithm, Your Views -
Hi Everyone, I am planning to write an encryption utility. I want to know what’s the best algorithm available. What’s the best algorithm available at the moment? How about DES, PGP and Blowfish are they crackable (realistically) or is there any better algorithm available apa

What's the universal formula for compression algorithm -
Does anybody know? There has to be a universal law of compression of data no matter what the algorithm. Like if you wanted to compress 01100010 (98) and 00010111 (23) into less or equal to 8 bits, what will that algorithm be when 1 or more numbers contain a different algorithm of do

Compressing a Byte array -
I have an array of Bytes and I need to compress it, no certain algorithm I just need to create an algorithm that will look for common patterns in the byte array then say replace them for a shorter pateren that is defined at the begining. The only problem is I don't know an algorithm th

Noise reduction algorithm required -
I need a simple and fast algorithm to get rid of noise on monochrome images. A typical image is attached here... I have about 10000 such images and they all need to be cleaned up a bit. Any ideas? Needless to say the text must remain undamaged by said algorithm. I plan to load

Design an algorithm to validate and store -
Im new to VB and i have been reading alot into it. I have come across 4 problems in which i have had trouble completing. I have little idea of what is required but i dont know how to do it. 1) Design an algorithm to validate the data controls on the form and store the values int

what is Bigram algorithm -
Hi all, can you tell me what is the bigram algorithm ? and could you show me what can i download the document for the algorithm? i used to download amny documents about this algorithm also but after is read it got nothing about tha. please help me. Best regards, Thirith.

YEAH!!! But Still 1 Problem -
Well I have figured out the basics of decoding an mp3 file in VB and mapping it to a wave device using LOTS of mp3 documentation on the internet. One problem I have is trying to find an algorithm to convert a byte value into its relevent bits. I could hardcode all 256 of them but I was

XML: algorithm to aggregate -

Hi! My question is about Algorithms.. I have two numbers.. for example :- First Number: 87519756113659 Second Number:87719753497097 There is an Algorithm used here to generate these numbers.. I can get more numbers generated from the same algorithm.. but how to know

RSA (Again :o|) Any help -
Hi, I'm trying to make a small encryption program that uses RSA, but it's slightly easier (I think this would make it easier anyway!). But, I'm still having problems with it. What I would like to do is still use the normal RSA algorithm, but instead of coming up with a random s

Scanline algorithm -
Hi all, I'm in need of a scanline algorithm that's capable of filling in a polygon. (I'd use the API functions to fill in my polygons, but I want each individual pixel in the polygon to be of a different shade, based on my funky lighting algorithm). Anyone got one handy? (And wh

PGP, Encryption & Stuff -
I have to use PGP to encrypt a database table to ftp to a bank. What is the best algorithm to use to accomplish this. It should be a simple yet fairly secure algorithm, not like the shift algorithm.... Wouldnt the key need to be encrpted to?? I am new with encryption, is there a good w

Euclidean algorithm can't handle 2/3 -
I'm currently using an implementation of the Euclidean algorithm in a program I am developing in order to take a decimal answer and display it as a fraction. For example, I entered 2/18, the program would use the Euclidean algorithm to display the answer as 1/9, instead of .1111111111

DES Algorithm -

Line algorithm -
Hi, This is the best place where I can post this, I think Say, I have a subroutine called drawline, which accepts as parameters: x1, y1, x2, y2 We have a screen, and on point (x1,y1) we start drawing our line to (x2,y2). Each pixel on the line should be determined by an algo

Need a smart person to fix this algorithm -
Take a look at the smooth sort algorithm in this project. First person to fix the bug gets a credit in the final program. For more information on the problem, double-click the smooth sort algorithm from the main screen. The best way to reproduce the errant behavior is to isolate

How does Graphics.DrawImage resize the image -
I'm writing an open source image signature/comparison system. I have the algorithm down, but in certain circumstances, the image has to be resized (possibly on only one axis) before the signature is generated. (I'll explain why, if you really need me to.) The problem is this: I'm pl

Can you help me identify this algorithm -
I have dreamed up a simple algorithm for finding small prime numbers. It is such a simple (and memory hungry!) alg that I reckon it must have been postulated by someone in the last few millenia. I was wondering if it is a famous one or one that is so crappy that its been ignored.
