Actionscript 3 :: Algorithm To Generate All Possible Letter Combinations Of Given String Down To 2 Letters

Algorithm to generate all possible letter combinations of given string down to 2 letters
Trying to create an Anagram solver in AS3, such as this one found here:
[URL]
I'm having a problem wrapping my brain around generating all possible letter combinations for the various lengths of strings. If I was only generating permutations for a fixed length, it wouldn't be such a problem for me... but I'm looking to reduce the length of the string and obtain all the possible permutations from the original set of letters for a string with a max length smaller than the original string. For example, say I want a string length of 2, yet I have a 3 letter string of "abc", the output would be: ab ac ba bc ca cb.
Ideally the algorithm would produce a complete list of possible combinations starting with the original string length, down to the smallest string length of 2. I have a feeling there is probably a small recursive algorithm to do this, but can't wrap my brain around it. I'm working in AS3.

I've searched high and low for a simple function that gives me all the possible combination of a set of characters with no avail. Anyone here got enough of a maths brain for this one? I want a function around the likes of this: possibleCombinations("abc"); which returns an array: "abc", "ab", "a", "cba", "cb", "c", "..." ETC You'd be doing me a hug favor as a deadline depends in the delivery of this code.

Trying to get the first letter of a String to capital, and the rest of the String must be lower case. I think I am on the right tracks with the first letter, but not sure how to make everything else forced to be lowercase. Heres a bit of info because I might need to change things. I load in a flashvar vaiable by
var flashVar3 = root.loaderInfo.parameters.myVar2;
I am not to sure what data type this would be, not sure what flashvars comes as. I am then doing
var oldStr:String = flashVar3;
var newStr:String = oldStr.charAt(0).toUpperCase() + oldStr.substr(1);
tf3.text=" "+ newStr;
I dont know if the first line is an issue, because i dont know if flashvars comes as a String. But what I have generally would work on the first letter. Not to sure how I can force the rest of the String to be lowercase though. At this moment in time, I get the error TypeError: Error #1010: A term is undefined and has no properties.
But I am not sure if this is because my flashvars variable is defined at runtime. Any advise on getting all of this working would be great.

For a rather complex search function I need to get the first letter of each word entered into an input field. At first glance this may not seem like a big problem if every word is neatly seperated by a space.
Although people can enter whatever they want into the field I only want to work with the words that start with a-z or A-Z.
I'm having a bit of trouble figuring out how I can determine if a character in the string falls into this selection. One of the possibilities is to use charCodeAt(), but that's rather rough. I can walk through the string using indexOf() but I may have trouble finding the next word if characters other than a space come into play.

Is there a way to take all the letters out of a string and then use it as a integer?If that is not possible, is there a way to take the first three letters off a string variable? i.e. make myVariable='pic1' into myVariable = '1' Yes? no?

I'm trying to take the letters I have in a string var, eg "EXAMPLE", and display them in a textField like so:[code]I've got the textfield set large enough to accomodate the text.Is there a better way to split a string into individual letters, and then display them in a field one above the other?

I've made some code that loads a line from a text file as a string and puts it into a dynamic field. What I want to do is randomize the letters of the string, but I can't seem to find any functions that do so. Anyone have an idea as to how you do this?
Code:
var url:String = "test.txt";
var loader:URLLoader = new URLLoader();

I'd like to build a cipher in AS2, and I was wondering if there's any way for me to search a string for a specific letter/word?
Example:
someTextBox.text = "Lorem ipsum";
Can I search inside of that string for an "m" and then subsequently alter that letter?

I neeed to insert spaces in front of capital letters in a string. the string contains the name of a country instance for example demRepublicOfCongo. I would like to scan the string and inset spaces before each capital letter so that the contents of the above string would become dem Republic Of Congo, for eaxmple.I found some code that It is posted below.
//Works out country name from string
var country:String=counrtyinstance.replace("_mc","");
var re:RegExp = /(?<=[a-z])([A-Z])/g;

Given the following example SWF: Sample Notice how with the words "enthusiast" at the end of the first line and "write" at the end of the second line, that they start to type out on the first line but after a few letters they are bumped.
I understand this is the correct behavior, but is there a way for "enthusiast" to begin being typed on the second line, and "write" on the third line instead of being bumped during the typing?
Currently I am thinking of doing a search ahead mechanism, so it finds the next word in whole, then makes that the active word to print, temporarily print it, see if it increases the numlines, and if it does insert a line break and continue writing. But it seems fiddly.

I've got an inputfield.OnChange Event Handler.When someone types a letter, i want the letter to become 0, then 1, then 2, and so on until 9 and then i want the letter to be there.And when they click on another letter, same effect happens.so at the end if i typed, "testing", each letter scrolls 0-9 like a roll dial and settles on the letter typed.What i've managed to do is make it work, but if i type at normal speed and not slow, i end up getting something like: t32t43g

I have this hyperlink, but I want the program to look through the hyperlinked page and pick out random words within a certain perameter. So like, it has to have a noun, verb, and pretty much end up a normal sentence that is completely out of context. Something like, "The doppler effect enjoys pine needles in the cornfield."
Is it even possible to get that? Can you even generate random string off a hyperlink? Can actionscript even browse through a hyperlinked file?
