StdoutRead problem...

[qwer85]

Why my script doesn't work?

#include <Constants.au3>
#include <GUIConstants.au3>

GUICreate("CMD Console", 400, 400)
GUISetState(@SW_SHOW)
$myedit=GUICtrlCreateEdit ("", 10, 10, 380, 380)

$var = Run("cmd", "c:", @SW_HIDE, 2)

While 1
    $line = StdoutRead($var)
    If @error Then ExitLoop     ; This line doesn't function. Why?
    GUICtrlSetData($myedit, $line & @CRLF)
    $msg = GUIGetMsg()
    If $msg = $GUI_EVENT_CLOSE Then ExitLoop
    Sleep(100)
Wend

ProcessClose("cmd.exe")

Maybe...

#include <Constants.au3>
#include <GUIConstants.au3>

GUICreate("CMD Console", 400, 400)
GUISetState(@SW_SHOW)
$myedit = GUICtrlCreateEdit ("", 10, 10, 380, 380)

$var = Run("cmd", "c:", @SW_HIDE, 2)

Sleep(500)
$line = StdoutRead($var)
If @error Then MsgBox(0,"","ERROR")    ; This line doesn't function. Why?
GUICtrlSetData($myedit, $line & @CRLF)
ProcessClose("cmd.exe")

While 1
    $msg = GUIGetMsg()
    If $msg = $GUI_EVENT_CLOSE Then ExitLoop
Wend

qwer85, StdoutRead will not set an error flag until the cmd.exe proces has been ended. Currently in your script, the cmd.exe keeps running forever. When you close cmd.exe through task manager you see that your GUI will close and your script will exit.
