User Enters A Password - Must Be At Least 3 Characters Long - At Least 1 Number And 1 Alphabet Character
Mar 28, 2012My homework assignment is to create a project where a user enters a password that must be at least 3 characters long with at least 1 number and 1 alphabet character. After that the password has to be encrypted so that vowels become X, numbers Z, and it reverses. For example, a password of CS2301 would be ZZZZSC. There's supposed to be Loops to extract 1 number/letter at a time and search for them in the string to validate, and I don't know what to do. The form itself has a Text Box to enter a password and a label to display the new one, and a Go button.
This is what my code looks like so far.

Option Explicit On

View 3 RepliesEnumerate The Localized Alphabet In C#?
Apr 15, 2011Quickest way to enumerate the alphabet in C#
Because I need to get all the characters of the alphabet OF AN ARBITRARY (variable) LANGUAGE, and that in the correct ordering sequence.
How can I do that without knowing the alphabet of every possible culture/language? System.Gobalization.Cultureinfo for example has information on date format, and a sorting method, and codepage info. But not info on the alphabet itselfs. Forthermore 'A' to 'Z' ordering iterating won't do, because German for example has characters such as ÄÖÜ, which are after 'Z' in the codepage numbering, but follow after aou when sorting.
Can I somehow use the codepages to get all the characters, and sort them somehow ? By 'all the characters' I mean all letters, including numbers, but not punctuation marks. And possibly only upper XOR lowercase.

View 13 RepliesNumeric And Non Numeric Data?
Jan 22, 2010I am reading a data file and storing them in an array of string.Data is random, could be like "1","2","133,18" but sometimes there can be missing values like "?".Once I load the data in the array, I want to check if at least a majority (like 60% of them) are numeric values.If yes, then I wanna track down the higher and lowest value in the array, and output a range of 5.Loop through the array
If 60% of them are numbers (integers or decimals) then find highest value, find lowest value end if produce range
If for example lowest = 1 and highest = 100, range of 5 means 0,20,40,60,80,100 (so 5 ranges are 0-20, 20-40, 40-60, 60-80, 80-100).Also if the ranges turn to have decimals due to weird numbers, I would like to round them up.My problem is, in order to find highest and lowest when there are non numeric values in the array like "?", how should I handle those? I was thinking of something like Double.NaN but I would have to have an array of doubles.

WasSwapped is used to keep track of whether the letters been used in the cipher already and alphabet is just a list of the alphabet in order. All arrays and lists are size 26.

Make Program That Counts The Frequency Of Each Letter In The Alphabet?
Feb 22, 2012I'm trying to make this program that counts the frequency of each letter in the alphabet for a set of ciphertext, the calculation i want to do is:lettersum*(lettersum - 1) + lettersum*(lettersum - 1) for however many letters example: User puts aabbcc in the ciphertext box , the output should be
2(2-1)+2(2-1)+2(2-1) =6 If the user inputs aaaaab the output should be 5(5-1)+1(1-1) = 20 The code I have so far only counts the last number of letters for example: aabbcc only reads the cc part and only outputs 2(2-1) = 2 instead of 2(2-1) + 2(2-1) + 2(2-1) = 6.The code below is part of a button_Click item
