RegisterHotKey by PaulE on 05-15-2011 at 03:21 PM
Hello Folks,
I'm trying to use the RegisterHotKey function, however.. I'm stuck. What I want is to let my script react on two hotkeys (Alt+Q and Alt+W). Can anyone help me a bit with it? This is what I got so far, but I don't know what to do next:
js code:
function OnEvent_Initialize(MessengerStart)
{
if(Messenger.MyStatus !== STATUS_UNKNOWN)
{
OnEvent_SigninReady(Messenger.MyEmail);
}
}
function OnEvent_Uninitialize(MessengerExit)
{
}
function OnEvent_SigninReady(Email)
{
_hotkey = MsgPlus.CreateWnd('Hotkey.xml', 'WndHotkey', 2);
_hotkey.RegisterMessageNotification(WM_HOTKEY, true);
// Interop.Call('user32', "RegisterHotKey", _hotkey.Handle, <- Stuck from here
}
function lobyte(w) { return w & 0xff; }
function hibyte(w) { return w >> 8; }
This is my Hotkey.xml
xml code:
<?xml version="1.0" encoding="UTF-16"?>
<Interfaces xmlns="urn:msgplus:interface" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:schemaLocation="urn:msgplus:interface PlusInterface.xsd" Name="Message Notifier">
<Window Id="WndHotkey" Version="1">
<Attributes>
<ShowInTaskbar>False</ShowInTaskbar>
</Attributes>
<DialogTmpl/>
<Position Width="0" Height="0" />
</Window>
</Interfaces>
So what do I have to put as parameters for the Call() function, and how can I make this script execute two different functions when the hotkeys are being pressed?
Thanks in advance!

You can register hotkeys like this:
jscript code:...where ID is a number relating to the action (so you can tell what combination was pressed later), Mods is the numerical representation of all modifiers you wish to use (in your case, Alt = 1), and Key is the code for the keys you wish to use (Q = 81, W = 87 - see my function below for generating key codes for letters).
Interop.Call("user32", "RegisterHotKey", _hotkey.Handle, ID, Mods, Key);
Process key combinations using the message notification:
jscript code:The wParam holds the ID you set when you registered the hotkey.
function OnWndHotkeyEvent_MessageNotification(PlusWnd, Message, wParam, lParam)
{
switch (wParam)
{
case 1:
// ...
break;
}
}
You will also need to unregister hotkeys (i.e. when the user signs out, or when Messenger is closed - whichever is more appropriate), otherwise they will not register next time.
jscript code:Use the same ID as when you registered them.
Interop.Call("user32", "UnregisterHotKey", _hotkey.Handle, ID);
Also, is WM_HOTKEY (= 0x312) defined?
You can use this to convert letters and numbers to codes, and back again:
jscript code:Use Codes['A'] or Codes['1'] to generate codes, or Codes[70] to convert back.
var Letters = "0123456789 ABCDEFGHIJKLMNOPQRSTUVWXYZ".split("");
var Count = 0x30;
var Codes = [];
for (var Letter in Letters)
{
if (Letters[Letter] !== " ")
{
Codes[Count] = Letters[Letter].toString();
Codes[Letters[Letter]] = Count;
}
Count++;
}
