[RESOLVED] Limiting input text to unique characters

[Rajada]

I probably don't want to have to create a variable for every character, whether or not it is just 26 of them for just the uppercase alphabet I'm using. It seems like it would be a ton of code to reset those variables.

Since its limited to ten characters, and I have an 'Apply' button basically, couldn't I just compare each character to every other character and if at least one matches another just return a message stating the entry is invalid? Oh, I just realized I need to enforce a minimum character count of ten for this to work too. So maybe I need to see if AS3 has any functions like PHP does that allow you to take apart strings and determine string length and such.

EDIT:

Haha! Nevermind then! All my OOP experience came in handy and I just used this which works like a charm...

function Decrypt(Event:MouseEvent):void
{
	var KeyString:String = InputBox.text.toString();
	var com1:Number = 0;
	var com2:Number = 0;
	
	if(KeyString.length < 10)
	{
		ResponseBox.text = "INVALID KEY! ERROR NO. 001";
		return;
	}
	else 
	
	myLoop: for(com2 = 0; com2 <= 10; com2++)
	{	
		if((KeyString.charAt(com1)) == (KeyString.charAt(com2)) && ((com1 < 10) && (com2 < 10) && (com1 != com2)))
		{
			ResponseBox.text = "INVALID KEY! ERROR NO. 002";
			 break myLoop;
		}
		else
			{
			if(com2 == 10)
			{
				com2 = 0;
				com1++;
			}
			if(com1 == 10)
			{
				BeginDecryption();
				break myLoop;
				
			}
		}
	}
	
}
