How to tell if a string contains some specified text

[zmar0519]

Hi, everyone. I was wondering if there was a way to check if there was a way to tell if the user enters some text into a text area and do something about it. That is, the user inputs "Login" at the end of a string and I want it to delete "Login" and add "Type the password password: ". How do I do this? Any help would be appreciated. If this is still not clear, then please post a comment.

I think

userString.Contains("stringToSearchFor")

would return either true or false.

If you are using C# then heres an example, with comments:

//Load your stuff

using System.Collections;

using System.IO;

namespace example

{

public void justAnExample()
{

//Just a streamreader to read a string from a doc

 StreamReader sr = new StreamReader("C:/Whatever/example.txt")

//Heres what you want, sr.IndexOf(“LALALA”) finds where the string of “LALALA” is located
//in the stringreader. If it is not there it’s -1, so if it’s greater than -1 it’s there.

 if (sr.IndexOf("LALALA") > -1)

     {

        doStuff();

     }

}

}

If you're using C#, take a look at the IndexOf() and ToUpper() string methods.

If you're using JavaScript, take a look at the IndexOf() and toUpperCase() methods.

you can do this

if(yourString in stringToSearchFor)

[santi5655]

here is an easy example for doing this

var passwordEnterString : String;
var correctPassword : String;

function Update()
{
         if(correctPassword in passwordEnterString)
                passwordEnterString = "correct";

}

Aren’t strings immutable? I’m starving for a similar method for destroying clones on a ticker.
