Refreshing a ListView

[Naufuge 0]

My script uses a list view that you are able to add, and delete items from. The items are saved in a text file, which is "#included" after creating the listview. my Main Loop calls two functions to update the lists. but when it is running there is a Massive Flicker. How can i stop this?

My loop is:

While 1
    Update_SettingList()
    Update_LogList()
    $msg = GuiGetMsg()
    Select
    Case $msg = $GUI_EVENT_CLOSE Or $msg = $File_Exit
        FileDelete(@ScriptDir & "\Configuration Files\Temp_Log.dbl")
        FileWrite(@ScriptDir & "\Configuration Files\Temp_Log.dbl","")
        ExitLoop
...  ...  ...  ...  ...  ...   ...  ...  ...  ...  ...  ...   ...  ...  ...  ...  ...  ...   ...  ...  ...  ...  ...  ...   ...  ...  ...  ...  ...  ...

My Function for updating is:

Func Update_SettingList()
    GuiCtrlDelete($Setting_List)
    $Setting_List = GUICtrlCreateListView("Setting Name|Status|Location|Runs|Failed|Total Time|Ping|Restarts", 0,0,740,155)
        #include <Configuration Files\Settings.dbl>
EndFunc

it looks like you have things in the loop that don't need to be done more than once... that will lead to flickering etc.

I dont NEED them in the loop, but it would make the app run more efficently if they where...

i would suggest setting a flag, $datachanged = 0

if $datachanged then

; do your updates

$datachanged = 0

endif

technically, unnecessary repetition IS inefficiency.... if you post a full script i'll see if i can't optimize it some for ya. (after i work out your signature)

Hi,

Idon't understand how you are writing the individual listview items..

Are they in the include?

Anyway, are you using; (before and after each recreate/ rewrite of listview)

Func _LockAndWait2()

Local $Cursor_WAIT

GUISetState(@SW_LOCK)

GUISetCursor($Cursor_WAIT, 1)

EndFunc ;==>_LockAndWait2

Func _ResetLockWait2()

Local $Cursor_ARROW

GUISetState(@SW_UNLOCK)

GUISetCursor($Cursor_ARROW, 1)

EndFunc ;==>_ResetLockWait2

to stop flicker?
