Sorry for the double topic, I've spent ages trying to figure this out and a search yields no results

I'm using this and I've got everything working and modified to my needs; The script and php communicate and it executes perfectly, but as soon as I try to do the following:

jscript code:

---

return xmlhttp.responseText;

---

quote:

---

Error: The data necessary to complete this operation is not yet available.
(code: -2147483638)

---

jscript code:

---

xmlhttp.send(data);

---

You should only use the responseText property when (xmlhttp.readyState == 4) and (xmlhttp.status == 200). Try that and see if it works.

code:

---

(...)
xmlhttp.onreadystatechange = function () {
   if (xmlhttp.readyState == 4 && xmlhttp.status == 200) {
         // Data is available now
         DoSomethingUseful(xmlhttp.responseText);
      }
   }
}
xmlhttp.send();

And forget about while loops for doing that. Seriously. Forget it.

Now that is very strange!

Could you please post your complete code here, preferably in [code]...[/code] tags?

code:

Script is starting
Script is now loaded and ready
Function called: OnEvent_ChatWndSendMessage

jscript code:

function OnEvent_ChatWndSendMessage(ChatWnd,Message){
  for(var e = new Enumerator(ChatWnd.Contacts);!e.atEnd();e.moveNext()){
    rEmail = (e.item().Email);
    }
    // return Email;
    // ^ use to echo contacts email address
    // return Messenger.MyName;
    // ^ use to echo current users name

if(Message.substr(0, 2) === "+1") {
var name = Messenger.MyName;
var gEmail = Messenger.MyEmail;
var rMessage = (name + ' has rewarded you with a +1!');

// database call

var url = "http://plusone.samryan.co.uk/test.php";
var data = ('rEmail= ' + rEmail + '&gEmail=' + gEmail);

xmlhttp.onreadystatechange = function () {
   if (xmlhttp.readyState == 4)
      if (xmlhttp.status == 200) {
         // Data from URL was retrieved successfully
         // Data is saved in the variable xmlhttp.responseText
      } else {
         // The server returned an HTTP code other than 200
   }
}
// end database call
return xmlhttp.responseText;
// else

}else{
return Message;
}

      Debug.Trace(xmlhttp.readyState);
//  ending of script
}

Okay, I now see where your problem is.

It is not possible to replace your sent message with a response text retrieved through an asynchronous XMLHTTP request. This is because if you return something in the onreadystatechange event, it'll be returned in the onreadystatechange function, not in the OnEvent_ChatWndSendMessage!

Therefore, there are 2 ways to solve this:

• Make the call synchronous by doing:
  

  jscript code:

  ---

  xmlhttp.async = false;

  ---

  after "var xmlhttp = new ActiveXObject('Microsoft.XMLHTTP')". This way, you can drop the onreadystatechange event and retrieve the response text immediately after you call xmlhttp.send(). However, this may lag your Messenger for a small period of time and is therefore not recommended.
  
• Keep your asynchronous call by returning an empty string and use ChatWnd.SendMessage in the ready state event function.

jscript code:

---

function OnEvent_ChatWndSendMessage(ChatWnd, Message){
    for(var e = new Enumerator(ChatWnd.Contacts); !e.atEnd(); e.moveNext()){
        rEmail = (e.item().Email);
    }
    // return Email;
    // ^ use to echo contacts email address
    // return Messenger.MyName;
    // ^ use to echo current users name

    if(Message.substr(0, 2) === "+1") {
        var name = Messenger.MyName;
        var gEmail = Messenger.MyEmail;
        var rMessage = (name + ' has rewarded you with a +1!');

        // Database call
        var url = "http://plusone.samryan.co.uk/test.php";
        var data = ('rEmail= ' + rEmail + '&gEmail=' + gEmail);

        Interop.Call("wininet.dll", "DeleteUrlCacheEntryW", url);
        var xmlhttp = new ActiveXObject("Microsoft.XMLHTTP");
        xmlhttp.open("GET", url, true);
        xmlhttp.setRequestHeader("Content-type", "application/x-www-form-urlencoded");
        xmlhttp.setRequestHeader("Content-length", data.length);

        // Declare a ready state change event
        xmlhttp.onreadystatechange = function () {
            if (xmlhttp.readyState == 4) {
                if (xmlhttp.status == 200) {
                    // Data from URL was retrieved successfully
                    // Now we can send the response text
                    ChatWnd.SendMessage(xmlhttp.responseText);
                    // Any other code for when the request was succesful
                    // should go here
                } else {
                    // The server returned an HTTP code other than 200
                }
            }
        };
        // After we declared a ready state change event,
        // we can start the request. It won't get started
        // any earlier than this!
        xmlhttp.send(data);
        // The script won't wait for the request to finish.
        // Therefore we'll return an empty string so the
        // declared event can send a message later.
        return "";
    }
}

Thankyou What I had above was copy and pasted together with guessing included, I've never used any of this before so outside of the PHP I was lost

Thanks though, much appreciated. Now to complete it

Any ideas why it adds a gap to the message?

If I typed "+1" it returns the success message, but like so:

person says:
Success!

Someone else:
What's with the gap?

I've checked the code and I've not got anything there that should cause it, however if I copy and paste it;

It may be your test.php which gives some extra characters?
If I access the test.php on your server, it gives me:

quote:

---

No user with this email exists

with a tab character and a new line character at the end. Maybe you should check your code to see if there are no blank characters in front or after your <?php ... ?> tags?
