Hey guys! im trying to make a prank where my friend installs the script and i can make his window invisible by typing [alpha]1

I found this

code:

---

// TRANSPARANT

function Huhu_wndAlpha(alph){
    var allwnd = Messenger.CurrentChats;                // Get opened chat window
    var e = new Enumerator(allwnd);
    for(; !e.atEnd(); e.moveNext()){
        var cwnd = e.item();
        if(alph!=0)Huhu_alpha(cwnd.Handle, alph);
        else Huhu_alpha(cwnd.Handle, Math.round(Math.random()*255));
    }
}

function Huhu_alpha(hWnd, alph){
    var Msg;
    var nMsg = Interop.Allocate(4);
    var GWL_STYLE = (-20);
    var LWA_ALPHA = 0x2;
    var WS_EX_LAYERED = 0x80000;
    var WS_EX_TRANSPARENT = 0x20;
    if(alph>255)alph=255;
    Msg = Interop.Call('user32', 'GetWindowLongW', hWnd, GWL_STYLE);
    nMsg.WriteDWORD(0, (Msg | WS_EX_LAYERED));
    Interop.Call('user32', 'SetWindowLongW', hWnd, GWL_STYLE, nMsg.ReadDWORD(0));
    Interop.Call('user32', 'SetLayeredWindowAttributes', hWnd, 0, alph, LWA_ALPHA);
}

code:

---

function Huhu_ChatWndReceiveMessage(ChatWnd, Origin, Message, MessageKind){
    if(Origin!=Messenger.MyName){                    // If the receive message isn't send by you
        if(Message.indexOf("[alpha]")!=-1){            // Apply alpha filter
            var tmp = (Message, "[alpha]");    // Get text after the command
            if(tmp=="")Huhu_wndAlpha(0);
            else Huhu_wndAlpha(parseInt(tmp));
            return '' // hide the command
        }
     }
     
}

Not that we condone this type of prank but there are a few things you can do. Firstly using transparency to hide the window is ok but you can use ShowWindow instead.

Firstly the function Huhu_ChatWndReceiveMessage doesn't appear to be called anywhere (unless there is parts of your script missing).

Secondly this line

Javascript code:

---

var tmp = (Message, "[alpha]");

I'm sorry im new to scripting i just read abit of the doc

I'm trying to make it when i type the command [alpha]1 it will make his chat window invisible until i type [alpha]255

would it be possible for you to have a go at trying to do it please?

greatly appreciated

What you are asking for is really easy to achieve. However on the forum we tend not to promote scripts that are more of an irritation then anything.
