I'm looking for some function to put together every possible combination of letters and number to create a string that is 14 characters long. I have found ways to make every possible combination of letters and numbers seperately. However, I've never run across anything to come up with them together. Every string created must contain letters and numbers.I just have no idea where to start on this one.

I'm trying to produce every possible combination of the letters in a word, however I've been very unsuccessful at figuring this out.
I can't seem to grasp what I need to do to get this working, I've been at it for the last four hours or so.for example, the word "one" would produce: one, oen, eon, eno, noe, neo.
I have a windows based application using vb.net 2005 . My application , i have an array. The array contains 5 numbers. The numbers are,
3, 7, 2, 8 ,1.
I want to get the best combination of sum is 10 by using code .How will i do?
VS2010
VB
I would like to be able to add every combination of a list of numbers to determine which combinations equal a specific result.
Simple Example:
List: 2, 4, 6
Result: 10
How many and which combinations of numbers result in the number 10? The correct anwser is only one which is 4 + 6 = 10. The example is simple but the actual list may contain as many as 10 - 15 decimal numbers.
I have thought of the following as a possible way of checking each combination by using binary:
- There are 3 total number so the possible combinations would be:
123 - Three numbers
000 - Add no numbers
001 - Add the last number
[Code].....
However, I don't know how to actually match up the bitwise bits to the numbers in the array to actually add. Example:
101 - I should check if 2 + 6 != 10 per the example above so this wouldn't satisfy the result... does this make sense? The answer would be 4 + 6 = 10.
how to check and add all combinations from a list of numbers to determine if the result is a specific number?
Number1 = String.Concat(2, 106, 15, 233) Which will be 210615233.I am dealing with a problem in which I want to join some numbers then I come back again and split them up. The problem here I cannot save the original combination. Is there an Anti-concat method with saving the original combinations?For example, if I joined 3, 10, 4, 0 and 323 = 31040323. After some operations in my code I want to come back and split them up to the original combination of (3,10,4....etc). Please note that I am doing this not for one number, it is for many numbers.
View 5 RepliesI'm working on a program and in it I need to store all combination's of the numbers 1,2,3,4. I would like each combination to be it's own array, and instead of creating 24 different arrays (there are 24 different combinations 1,2,3 and 4 can be arranged) I was wondering if it's possible to create a nested array like so:
[ [1,2,3,4], [1,2,4,3], [1,3,4,2], [1,3,2,4] .......]
That way, I'd be able to reference index 2 of the above array and have the array [1,3,4,2] returned.I looked into multidimensional arrays, but this would require me calling each index of the row and column.I also looked into making a Structure in which there was an array that could hold 4 numbers, but wasn't sure if going that method would be practical or not.

im a student still learning and im stuck. im writing a program that returns the ip address, splits it in to parts, and now i need it to return a string of letters for other parts to use. EX.
ip address 127.0.0.1 will look like ABG.XXX.XXX.XXA
( i would like to set 0=X so it is easier to pick out the actual
numbers)
I am able to split it and display each part and rewrite it to textboxes without the "." but i dont know where to begin to change the numbers to the letters i need.
I'm on VS 2008 I have one form contains many textboxes,when I write in one textbox (UserName) the letters and numbers should distribute to the other texts where each textbox has only one letter or number from the original text to get them ready to be encrypted.
What code I can use in text change event that takes the whole text and throw it in the other textboxes so each textbox has only one value ?
My listbox will accept any letter I add, but I can't get it to accept any numbers. I tried a case select for 1-100 and I couldn't get that to work either,

To complicate things a little, each combination needs to be different, ie. randomised but still according to the 'letter,number, letter' formula. There are plenty of examples of randomising strings such as passwords but I cannot understand how to achieve the above.
I'm brand spanking new to coding (as well as this forum). And I'm learning Visual Basic 2010 in School. Right now I am working on the following problem: "Use a masked text box to as a user to enter a phone number in a format as follows: (604)323-5819. Make sure you add input mask to the area code and phone number. Both the phone number and the area code are required. Then extract the area code and display it in a text box when a button is clicked." Here is my code, I've got it where I can input the number, and when the button is clicked (things actually appear in the text box!) however instead of getting the area code, I get "als" or alternatively if I put (0,3) I'll get "fals" I don't understand what I'm doing wrong or even where "fals" is coming from. Can someone please explain to me what I'm doing wrong? I've literally been at this since 4pm today and only just (midnight) able to get it to this point and I'm incredibly frustrated as to where these letters are coming from. [code]

My teacher wants us to make the passwords vary in length, include numbers, letters and upper case letters. I've been able to write code that prints out a random string but it includes unrecognized characters for most passwords. How would I write the code to create a random string that has parameters? (in this case upper case lower case letters and numbers).
