#include <GUIConstants.au3>
Opt("GUIOnEventMode", 1)
GUICreate("Test", 186, 155, 233, 191)
$box = GUICtrlCreateEdit("", 0, 0, 185, 89)
$text = GUICtrlCreateInput("test", 0, 104, 121, 21)
$send = GUICtrlCreateButton("send", 0, 128, 75, 25, 0)
GUICtrlSetOnEvent($Send, "_Send")
GUISetOnEvent($GUI_EVENT_CLOSE, "_Exit")
GUISetState(@SW_SHOW)

 While 1
     Sleep(0)
 WEnd
 
Func _Send()
If GUICtrlRead($text) = "" Then
MsgBox(16, "Error" , "Please write a message")
Else
    GUICtrlSetData($box ,GUICtrlRead($Text))
    EndIf
EndFunc

Func _Exit()
    Exit
    EndFunc

run this and type a few things and you'll see that it overwrites the first line but i want it to write to the second line and so on...

Use:

GUICtrlSetData($box ,GUICtrlRead($Text)&@CRLF, 1)

In stead of:

GUICtrlSetData($box ,GUICtrlRead($Text))
