Every Combination Of Letters And Numbers

May 19, 2009

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.

Jun 24, 2010

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.

Add Every Combination Of List Of Numbers

Nov 1, 2010

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?

Split Previously Joined Numbers To Original Combination?

May 17, 2010

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.

VS 2008 Nested Arrays - Tore All Combination's Of The Numbers 1,2,3,4?

Apr 14, 2010

I'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.

Generate Random Alternate Letters And Numbers?

Apr 6, 2012

What I am trying to do is create a form with a button and a list box. When clicked the button will generate a list of 3 or 5 characters that have alternate letters and numbers...eg.

q2h
a6j
z4p
d9k

[Code].....

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.

Getting Letters Instead Of Numbers In Extracting Area Codes

Jan 30, 2012

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]

Prevent Users Entering Letters Instead Of Numbers?

The app uses several forms to let the user enter information. In each form the info is entered into textboxes and dealt with elsewhere when the "Enter" button is clicked. A lot if the info entered is used in calculations and so must not contain alpha characters, only numbers.
