A simple text pasting GUI application

[HolmesShelock]

I am trying to develop a simple application which will accept text in a text box as input, stay on top and paste the same text to an application to another which can be switched the focus to. Essentially it is a variant of On-Screen-Keyboard type application. Below is my code. It is not working in a sense that the "Paste" function not working properly. Can someone please point out my mistake?

#NoTrayIcon
#include <GUIConstantsEx.au3>
#include <GUIConstants.au3>
#include <MsgBoxConstants.au3>

Opt("GUIOnEventMode", 1)

Local $hMainGUI = GUICreate("Text Paste", 700, 300, -1, -1, -1, BitOR($WS_EX_TOOLWINDOW, $WS_EX_TOPMOST, $WS_EX_NOACTIVATE))
;WinSetOnTop($hMainGUI, "", 1)
Local $btnPasteButton = GUICtrlCreateButton("Paste", 300, 250, 100)
$txtText = GUICtrlCreateEdit("", 50, 30, 600, 200)

GUICtrlSetOnEvent($btnPasteButton, "PasteButton")
GUISetOnEvent($GUI_EVENT_CLOSE, "CloseButton")
GUISetState(@SW_SHOW, $hMainGUI)

While 1
    ;Sleep(100)
    $msg = GUIGetMsg()
    If $msg = $GUI_EVENT_CLOSE Then ExitLoop
WEnd

Func PasteButton()
    Local $txtData = ControlGetText("", "", $txtText)
    ;$txtData = "Dip"
    Send($txtData, 0)
    MsgBox($MB_SYSTEMMODAL, "Pasted!!!", $txtData)
EndFunc

Func CloseButton()
    Exit
EndFunc
