Looking at the script of @mikell, and digging a little bit in the MSDN documentation, you could do something like this:

#include <Array.au3>
#include <EditConstants.au3>
#include <GUIConstantsEx.au3>
#include <GuiRichEdit.au3>
#include <WinAPI.au3>
#include <WindowsConstants.au3>

Opt("GUIOnEventMode", 1)

Global Const $ES_NOOLEDRAGDROP = 0x08, _
             $tagEndropFiles = $tagNMHDR & "; HANDLE hDrop; LONG cp; BOOL fProtected"

#Region ### START Koda GUI section ### Form=
Global $frmMainForm = GUICreate("A Form", 405, 293, 302, 218)
GUISetOnEvent($GUI_EVENT_CLOSE, "ExitApplication")
Global $hdlRichEdit = _GUICtrlRichEdit_Create($frmMainForm, "", 8, 8, 385, 273, BitOr($ES_NOOLEDRAGDROP, $ES_MULTILINE, $WS_HSCROLL, $WS_VSCROLL), $WS_EX_ACCEPTFILES)
                                                                                      ; ^ Needed to catch the
                                                                                      ; $EN_DROPFILES Notification Code
_GUICtrlRichEdit_SetEventMask($hdlRichEdit, $ENM_DROPFILES)
GUISetState(@SW_SHOW, $frmMainForm)
#EndRegion ### END Koda GUI section ###

                    $arrFileList = _WinAPI_DragQueryFileEx($hdlDrop, 1)
                    If @error Or $arrFileList[0] > 1 Or StringRight($arrFileList[1], 4) <> ".txt" Then
                        ConsoleWrite("The file(s) you dragged couldn't be read from the Rich Edit." & @CRLF)
                        ; Re-create the Rich Edit control
                        $hdlRichEdit = _GUICtrlRichEdit_Create($frmMainForm, "", 8, 8, 385, 273, BitOr($ES_NOOLEDRAGDROP, $ES_MULTILINE, $WS_HSCROLL, $WS_VSCROLL), $WS_EX_ACCEPTFILES)
                        _GUICtrlRichEdit_SetText($hdlRichEdit, ReadFile($arrFileList[1]))




Func ReadFile($strFileName)

    Local $hdlFile, _
          $strFileContent = ""

    $hdlFile = FileOpen($strFileName)
    If $hdlFile = -1 Then
        ConsoleWrite("Error while opening the file '" & $strFileName & "'." & @CRLF)
        $strFileContent = FileRead($hdlFile)

    Return $strFileContent


Thanks @mikell first ;)
Cheers :)

  • I will always thank you for the time you spent for me.
    I'm here to ask, and from your response, I'd like to learn.
    By my knowledge, I can help someone else, and "that someone" could help in turn another, and so on.
