need help with text in an edit box

[rcrosby]

I need help i'm a newbie and I wanted to know if there was a way to display the contents of a text file in an edit box when a user presses a button.

here's one way.

#include <GUIConstants.au3>

$filename = @ScriptDir & '\myfile.txt'

GUICreate("My GUI edit", 500, 500)  ; will create a dialog box that when displayed is centered

$myedit = GUICtrlCreateEdit("", 10, 10, 480, 450, $ES_AUTOVSCROLL + $WS_VSCROLL)
$btn = GUICtrlCreateButton("Read file", 225, 475, 90, 20)
GUISetState()


; Run the GUI until the dialog is closed
While 1
    $msg = GUIGetMsg()
    Select
        Case $msg = $GUI_EVENT_CLOSE
            ExitLoop
        Case $msg = $btn
            GUICtrlSetData($myedit, FileRead($filename, FileGetSize($filename)))
    EndSelect
    
WEnd
