odd loop question/problem

[testingtest]

i got a script with a GUI and my script updates the GUI every second or so but if I hit close on the GUI it sleeps for that second and the data being told in while loop to be send to the GUI has to be constant

While 1
    $nMsg = GUIGetMsg()
    Switch $nMsg
        Case $Cancel
            Exit
    EndSwitch
    Sleep(250)
    ;do something 
WEnd

i don't like seeing flicking while updating gui thats what the sleeps for

The code you showed does not reproduce the symptoms as it will not flicker the GUI because it doesn't change anything. Write a short demo that creates a GUI and shows how you are updating it.

Thats why you check to see if somehting needs updating before updating it on the gui

but i want it to have a good effect

#include <GUIConstants.au3>
$Example = GUICreate("Length = 16" , 252 , 120, 0 , 0 , $WS_CLIPSIBLINGS)
$Encode = GUICtrlCreateInput("133-A75-321-8K26", 8, 32, 233, 21)
GUISetState(@SW_SHOW)
While 1
    $nMsg = GUIGetMsg()
    Switch $nMsg
        Case $Cancel
            Exit
    EndSwitch
    Sleep(250)
    WinSetTitle($Example , "" , "Length = " & StringLen(GUICtrlRead($Encode)))
WEnd

This does a few things:

1. Adds $Cancel, which was causing an error

2. Eliminates flickering by only updating when there is a change (as danwilli suggested)

3. Tightens up the message loop so it doesn't miss clicking on things

Note that there is no Sleep(). GuiGetMsg() has an effective Sleep(10) built into it, so you don't need any more.

#include <GUIConstants.au3>

$Example = GUICreate("Length = 16", 252, 120, 0, 0)
$Encode = GUICtrlCreateInput("133-A75-321-8K26", 8, 32, 233, 21)
$Cancel = GUICtrlCreateButton("Cancel", 76, 80, 100, 30)
GUISetState(@SW_SHOW)

$sEncode = ""
While 1
    Switch GUIGetMsg()
        Case $GUI_EVENT_CLOSE
            Exit
        Case $Cancel
            Exit
    EndSwitch
    If GUICtrlRead($Encode) <> $sEncode Then
        $sEncode = GUICtrlRead($Encode)
        WinSetTitle($Example, "", "Length = " & StringLen($sEncode))
    EndIf
WEnd

works great but can you explain so I can learn from it please.

I thought <> was another form of =

and is it checking for input

Auto it doesn't use '!' for 'NOT', but '<>' would be equivalent to '!=' if it did.
