Is there a way and\or how would I go about "translating" the command output (for the progress) of this app (http://downloads.sourceforge.net/project/nfgdump/nfgdump/nfgdump-0.1/nfgdump-win32-binary.zip?r=http%3A%2F%2Fsourceforge.net%2Fprojects%2Fnfgdump%2F&ts=1332884584&use_mirror=iweb) to a progress bar, via AutoIT?

nfgdump.exe " & $DumporRestore & " /v /p /c /g /o=gz /d=\Dev" & $Drive-X & " /f=t:\LinuxImageStore\" & $ImgName & ".img"

nfgdump.exe dump /v /p /c /g /o=gz /d=\Dev0 /f=c:\Images\myimage.img

Note: if possible, an example would prove most helpful.

the command output looks like this:



Dump of '\Dev0\1 (C:)' started: (UTC) Wed Mar 28 22:42:38 2012

1.69% (comp: 62.34%), 9.82 MB/s, finished in 01:03:11.



it is the first portion, section or parameter (the one that shows 1.69%) of the output that i wish to transfer into a progress bar. however, i would like the throughput (9.82 MB/s and finished in 01:03:11 displayed as well, if possible).

Thanks.

Basically what needs to happen is you need to use STDOUT_CHILD to capture the output then you need to use StringSplit on the line using ',' as the delimiter.  This should give you an array with three  variables, you then use Number on the first variable to get 1.69 and then use Round to get a whole number, you can then update your progress bar with each of the three variables, i.e. $Var[1] = 2, $Var[2] = 9.82, $Var[3] = finished in 01:03:11

Below is an example, I haven't tested, but hopefully it'll get you started.
#include <Array.au3>
#include <Constants.au3>
#include <GUIConstantsEx.au3>
#include <ProgressConstants.au3>

Global $GUI_PROGRESS, $GUI_BUTTON, $RUN_NFGDUMP, $GUI_DATASTREAM, $GUI_FINISHEDIN

Example()

Func Example()
	Local $STD_NFGDUMP
	Local $DumporRestore = 'Dump or Restore'
	Local $Drive_X = 'Drive Letter'
	Local $ImgName = 'Image Name'
    GUICreate("NFGDUMP", 320, 100, 100, 200)
	GUICtrlCreateLabel('NFG Dump or Restore', 10, 15, 300, 20)
	GUICtrlSetFont(-1, 9, 800)
    $GUI_PROGRESS = GUICtrlCreateProgress(10, 40, 300, 20, $PBS_SMOOTH)
    $GUI_BUTTON = GUICtrlCreateButton("Start", 240, 70, 70, 20)
	$GUI_DATASTREAM = GUICtrlCreateLabel('', 10, 70, 70, 20)
	$GUI_FINISHEDIN = GUICtrlCreateLabel('', 80, 70, 70, 20)
    GUISetState()

    Do
        $msg = GUIGetMsg()
        If $msg = $GUI_BUTTON Then
			$RUN_NFGDUMP = Run("nfgdump.exe " & $DumporRestore & " /v /p /c /g /o=gz /d=\Dev" & $Drive_X & " /f=t:\LinuxImageStore\" & $ImgName & ".img", @SystemDir, @SW_HIDE, $STDERR_CHILD + $STDOUT_CHILD)
			While 1
				$STD_NFGDUMP = StdoutRead($RUN_NFGDUMP)
					If @error Then ExitLoop
				If StringInStr($STD_NFGDUMP, 'finished in') Then FNC_PROGRESS($STD_NFGDUMP)
			WEnd
        EndIf
    Until $msg = $GUI_EVENT_CLOSE
EndFunc

Func FNC_PROGRESS($PAR_NFGDUMP)
	Local $VAR_NFGDUMP
	$VAR_NFGDUMP = StringSplit($PAR_NFGDUMP, ',')
	If IsArray($VAR_NFGDUMP) And $VAR_NFGDUMP[0] = 3 Then
		GUICtrlSetData($GUI_PROGRESS, Round(Number($VAR_NFGDUMP[1])))
		GUICtrlSetData($GUI_DATASTREAM, $VAR_NFGDUMP[2])
		GUICtrlSetData($GUI_FINISHEDIN, $VAR_NFGDUMP[3])
		Sleep(1000)
	EndIf
EndFunc
