AHK - Sender() and Reciever()

These two functions can be used to send short messages between AHK scripts without the use of temporary files. Here are the two functions:

Sender(Message) {
   DetectHiddenWindows, On
   WinGet, List, List, ahk_class AutoHotkey
   Message := Message
   Loop, %List%
      SendMessage, % 1+4096,,,, % "ahk_id " List%A_Index%
   Loop, Parse, Message
      Loop, %List%
         SendMessage, % asc(A_LoopField)+4099,,,, % "ahk_id " List%A_Index%
   Loop, %List%
      SendMessage, % 2+4096,,,, % "ahk_id " List%A_Index%
}

Loop, 258
   OnMessage(A_Index+4096,"Reciever")
Return

Reciever(wParam, lParam, msg, hwnd)
{
   Global Message
   If (msg = 4097)
      Message=
   Else If (msg = 4098)
      SetTimer, Handler, -1
   Else
      Message .= chr(msg-4099)
}

Handler:
   MsgBox % Message
Return

And here is an example script. Run Recv.ahk before BCast.ahk.

; BCast.ahk
SetBatchLines, -1
Sender("Hello World!")
Sender(Message) {
   DetectHiddenWindows, On
   WinGet, List, List, ahk_class AutoHotkey
   Message := Message
   Loop, %List%
      SendMessage, % 1+4096,,,, % "ahk_id " List%A_Index%
   Loop, Parse, Message
      Loop, %List%
         SendMessage, % asc(A_LoopField)+4099,,,, % "ahk_id " List%A_Index%
   Loop, %List%
      SendMessage, % 2+4096,,,, % "ahk_id " List%A_Index%
}


; Recv.ahk
#Persistent
SetBatchLines, -1
Loop, 258
   OnMessage(A_Index+4096,"Reciever")
Return

Reciever(wParam, lParam, msg, hwnd)
{
   Global Message
   If (msg = 4097)
      Message=
   Else If (msg = 4098)
      SetTimer, Handler, -1
   Else
      Message .= chr(msg-4099)
}

Handler:
   MsgBox % Message
Return

AHK - Tray Recycler

This is a script that creates a recycle bin on your tray. It is a good example of how to monitor and manipulate the recycle bin on your computer, and contains some functions that you can use. Currently the only thing that doesn't work is the "Create Shortcut" option.
