Hi man, i need help....:I make this function:

function SetDataPatch(string){
var newstring =""
for (var i=0;i<string.length;i++){
newstring += "\x" + Hex(string.charCodeAt) + "\x00"}
Debug.Trace(newstring)
return newstring}}

but plus found this error,this is in italian but i'll try to translate it in english:

Lo script è stato fermato(the script has been stopped)
Errore: Prevista cifra esadecimale.(Error: expect digit hex)
       Linea: 43 Codice: -2146827265(line:43 Code: -2146827265)

i need to make a string like this "\xFF\x00\xFC" CAN SOMEONE HELP ME PLEASE??? Sorry for my english

So, if I understand, you have a string like

code:

---

var thing = "FF00FC";

---

code:

---

var new_thing = "\xFF\x00\xFC";

---

code:

---

function SetDataPatch(string) {
  var newstring = "";
  for(var i=0; i<string.length; i+=2) {
    var hex = string.substr(i, 2); //The hexadecimal character code
    var dec = parseInt(hex, 16); //The decimal character code
    newstring += String.fromCharCode(dec); //Adds the character to the string
  }
  return newstring;
}

and you need a function which makes it like this:

If so, this should do:

code:

---

function SetDataPatch(string) {
  var newstring = "";
  for(var i=0; i<string.length; i+=2) {
    var hex = string.substr(i, 2); //The hexadecimal character code
    var dec = parseInt(hex, 16); //The decimal character code
    newstring += String.fromCharCode(dec); //Adds the character to the string
  }
  return newstring;
}

In what way doesn't it work?
Because it works fine here

I think he wants a function which takes a string like

code:

---

var string = "ÿü"

---

code:

---

var newstring = "\xFF\x00\xFC"

---

code:

---

var newstring = "\xFF\x00\xFC\x00"

---

code:

---

function SetDataPatch(string) {
   var newstring = "";
   for(var i = 0; i < string.length; i++) {
      newstring += "\\x" + string.charCodeAt(i).toString(16) + "\\x00";
   }
   Debug.Trace(newstring);
   return newstring;
}

As far as I know, a function like this is completely useless because "a" === "\x61" (someone correct me on this one ).

To helpers: Try not to guess. If you aren't sure what is requested ask details and examples first

However, if the function is to give "\\xFF\\x00\\xFC\\x00" (which will display as "\xFF\x00\xFC\x00" to the user), you can use this:

code:

---

function SetDataPatch(string) {
   var newstring = "";
   for(var i = 0; i < string.length; i++) {
      newstring += "\\x" + string.charCodeAt(i).toString(16) + "\\x00";
   }
   Debug.Trace(newstring);
   return newstring;
}

---

---

code:

---

function SetDataPatch(string) {
    var newstring = "";
    for (var i = 0; i < string.length; i++) {
        // Get character and convert to hexadecimal

        var charHexcode = string.charCodeAt(i).toString(16).toUpperCase();
        // Since hexcode can be anything from 1 to 4 digits long
        // we need to properly format it by adding 0's.
        charHexcode = ("000" + charHexcode).substr(charHexcode.length-1);
        // The least significant part (last 2 digits) is the
        // first part to return in LE (little endian) format
        newstring += "\\x" + charHexcode.substr(2);
        // The most significant part (first 2 digits) is the
        // last part to return in LE (little endian) format
        newstring += "\\x" + charHexcode.substring(0, 2);
    }
    Debug.Trace(newstring);
    return newstring;
}

OK Thank all boys...I'll try to explain what i want better:
Well...this is the code I used:

code:

---

function Hex(number) {return number.toString(16).toUpperCase()}//function by CookieRevised

function SetDataPatch(string){
var newstring=0
for (var i=0;i<string.length;i++){
newstring += "\x" + Hex(string.charCodeAt) + "\x00"}
Debug.Trace(newstring)
return newstring}


function Patch(nAddress, sByteString) {
    var sBuffer = Interop.Allocate(++sByteString.length);
    for (var j = 0; j < sByteString.length; j++) sBuffer.WriteWORD(j, sByteString.charCodeAt(j));
    var hProc = Interop.Call("Kernel32", "GetCurrentProcess");
    Interop.Call("Kernel32", "WriteProcessMemory", hProc, nAddress, sBuffer.DataPtr, sByteString.length, 0);
}//Function By CookieRevised

---

code:

---

Patch(0x5F6D5C,"\x00\xFF\xFC")

---

No one can help me????

yes we can, but be patient please... In the mean time I very strongly suggest you read up on what strings are, how they are represented in memory and the differences between unicode, ascii and byte string and/or byte arrays. You'll really need this knowledge to understand everything involved. Otherwise, you just be copy/pasting code without knowing what you actually do.

This post will be updated when I finished writing my reply...
So no need to reply to this one either

"\x45\x00\x78\x00\x61\x00\x6D\x00\x70\x00\x6C\x00\x65\x00"

code:

function SetDataPatch(string){
var newstring=0
for (var i=0;i<string.length;i++){
newstring += "\x" + Hex(string.charCodeAt( i)) + "\x00"}
Debug.Trace(newstring)
return newstring}

code:

---

function SetDataPatch(sUnicodeString) {
    var newstring = "";
    for (var i = 0; i < sUnicodeString.length; i++) {
        // Get character
        var charCode = sUnicodeString.charCodeAt(i);
        // Get the low order byte (with an AND operation)
        // And write it as a new character
        newstring += String.fromCharCode(charCode & 0xFF);
        // Get the high order byte (with a right bit shift operation)
        // And write it as a new character
        newstring += String.fromCharCode(charCode >>> 8);
    }
    return newstring;
}

I said it involves some knoweldge of what unicode and ascii strings are and I said IF you simply copy/paste code you don't learn anything from it... What I said is actually nothing more than plain logic: if you want to know something, read up on some stuff about it. How is suggesting to read up on some background info about this while you wait on the detailed explaination, being any offensive??

This is correct as you state it, but do you exactly know what you just stated? Don't get me wrong though, I simply ask this because there can be a lot of confusion if one isn't used to deal with unicode vs. ascii vs. bytes. And as I said earlier it is absolutely vital that you post it in the correct form. eg: "\x45" is not the same as 0x45... "\x45" is 0x45 0x00
