Can't use Rich text control

[duongtnhat]

Hi, I'm a newbie and my english is bad , so it's difficult to understand, sorry!

So, my code

#AutoIt3Wrapper_Au3Check_Parameters= -d -w 1 -w 2 -w 3 -w 4 -w 5 -w 6
#include <GuiRichEdit.au3>
#include <GUIConstantsEx.au3>
#include <WindowsConstants.au3>
#include <Misc.au3>
Opt('MustDeclareVars', 1)
Main()
Func Main()
Local $hGui, $hRichEdit, $iMsg
$hGui = GUICreate("Example (" & StringTrimRight(@ScriptName,4) &")", 320, 350, -1, -1)
$hRichEdit = _GUICtrlRichEdit_Create($hGui, "This is a test.", 10, 10, 300, 220, _
   BitOR($ES_MULTILINE, $WS_VSCROLL, $ES_AUTOVSCROLL))
GUISetState()

While True
  $iMsg = GUIGetMsg()
  Select
   Case $iMsg = $GUI_EVENT_CLOSE
    GUIDelete()
    Exit
   EndSelect
  if _IsPressed ('0D') Then
   _GuiCtrlRichEdit_AppendText($hRichEdit, @CR & "This is appended text.")
  EndIf
WEnd
EndFunc   ;==>Main

When i presses Enter key, "This is appended text" is repeated many times, I do not want such, so please fix it.

Thank.

If you only want the text to be appended once then you need to wait until the key is no longer pressed before continuing.

Like this:

#AutoIt3Wrapper_Au3Check_Parameters= -d -w 1 -w 2 -w 3 -w 4 -w 5 -w 6
#include <GuiRichEdit.au3>
#include <GUIConstantsEx.au3>
#include <WindowsConstants.au3>
#include <Misc.au3>
Opt('MustDeclareVars', 1)

Main()

Func Main()
  Local $hGui, $hRichEdit, $iMsg
  $hGui = GUICreate("Example (" & StringTrimRight(@ScriptName,4) &")", 320, 350, -1, -1)
  $hRichEdit = _GUICtrlRichEdit_Create($hGui, "This is a test.", 10, 10, 300, 220, _  
  BitOR($ES_MULTILINE, $WS_VSCROLL, $ES_AUTOVSCROLL))
  GUISetState()

  While True
    $iMsg = GUIGetMsg()
    Select
      Case $iMsg = $GUI_EVENT_CLOSE
        GUIDelete()
        Exit
      EndSelect
    if _IsPressed ('0D') Then
      _GuiCtrlRichEdit_AppendText($hRichEdit, @CR & "This is appended text.")
      while _IsPressed ('0D')
      WEnd
    EndIf
  WEnd
EndFunc ;==>Main
