I am making a cipher solver in vb.net 2008 and I have made it solve ciphers for most ciphers but I can't make it do vigenere. I have got three textboxes named "EncryptionVigenere", "SolutionVigenere" and "Key" and a button called "SolveVigenere".
View 3 RepliesVigenere Cipher which I am trying to code in VB.Net. The main thing is to decrypt to plain text with keys provided. Currently, I did a small code to decrypt NIOZS to COMPU with the key LUCKY. This is done by storing the cipher text, the key text and the English alphabets in 3 different arrays each starting at index 0.
However, I do not know how to proceed on if my cipher text is longer. My cipher text file consists of texts in .txt, every 5 words are group together (e.g. NIOZS ECPQE TOGCG YMKQF E). The keys are all different in lengths. I also understand about checking letter frequency to deduce the key but I do not know from which point to start on.
Can anyone give me some pointers as to how I can get to start for my program? I tried looking for samples but some applets on the web wasn't exactly accurate or I can't start it up after I dl-ed.
i recently heard that it is possible to make a captcha solver in vb.net... well i really need this ?how to make my program scan the captcha image in a webpage and then save the answer of the captcha as a variable ?
View 1 RepliesI'm a student in a visual basic class and I've been asked to make a Sudoku solving program that writes to a table in access. I need help getting the values from my numeric updown boxes. I keep getting dimensional arrays and conversion errors when I wasn't trying to convert anything. I don't know what to do. I've been researching every night for days now, and I can't find any examples of coding a numeric updown box into an array. I have also thought about writing the numeric updown boxes into a table and then running checks on the rows, columns, and quadrants inside the table. Yet again, I can't seem to find any good examples of this either. I will continue researching and hopefully come up with something other than 64+ if inside if statements. I know in theory I could use arrays to compare the values, but I can't get it to work. I'm not entirely sure how to compare them with the quads either.

I'm currently trying to program a sudoku solver. I wrote pseudocode to establish what I'd have to do. One of the first things was to make sure each number in each of the 3 x 3 grids aren't equal to any of the others. Here is my attempt. I'm pretty sure I've gone the long way around tackling this but it was the only way I was fairly confident I knew how to do. txt1_2 means that it's the second number in the first 3 x 3 grid (from left to right). At the moment, even if I put in different numbers, it comes up with two of the 'error' message boxes. This code only focuses on the first 3 x 3 grid.

View 1 RepliesI'm writing an alphabet cipher that ciphers at random. It looks like it should work when I'm debugging it but when I look at the cipher key it comes out with duplicate letters like some of them weren't switched during the for loop. 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.

I'm trying to make a program (in VB 2008 Express Edition) that will take text (from a textbox) and then switch the letters (say a->f and A->F) and will put the result into a second textbox when I click a button. How do I code the program so that it will search through the textbox and find all of a certain letter (say a) and replace it, then search for the next letters (say b-z) and replace them?

Basically I use SetPixel on a given window to draw a line, work fine, but the line goes away as the window redraws itself.The problem: I have been putting timers and threads on it to make sure the line is being drawn. Is there any way to make a loop to make a certain thing happen about 10-30 times without taking in too much memory/CPU?
