$iMemo = GUICtrlCreateEdit

[Iceburg 1]

I have a script that runs 24/7 doing a variety of automation tasks for me. I have set up a On-Click GUI to change what the script is doing, and a small logging window associated with it.

Basically the only thing that I have an issue with is my display logging in the GUI. I have the following code, which is working fine, and in the 2nd day sometime I have iMemo get to the limit of 4096 lines. I have a button that clears iMemo but I miss all that logging while its full.

Is there a way to create iMemo so as it gets to 4096 lines, the first line rolls off, and the new line is added so I can always see the past 4096 lines, and not the first 4096 lines that filled it up?

$iMemo = GUICtrlCreateEdit("",245, 5, $GUIWidth - 240, $GuiHeight - 10, $ES_READONLY + $ES_MULTILINE + $ES_AUTOVSCROLL + $WS_VSCROLL)
GUICtrlSetFont($iMemo, 9, 400, 0, "Courier New")
GUICtrlSetData($iMemo, "(" & _Now() & ") Initializing..." & @CRLF, 2)
GUISetState(@SW_SHOW, $GUI)

I was looking over all the built in functions with edit controls, and could not find a simple step to your problem. However after playing with it for a bit, I think I have a rudimentary solution. instead of limiting to 4096, I made mine for 10 lines to check it. here is my entire write, I hope it helps, Or someone comes up with a better solution for you.

$GUIWidth=800
$GuiHeight=600
$GUI=GUICreate("Example",$GUIWidth,$GuiHeight)


$iMemo = GUICtrlCreateEdit("",245, 5, $GUIWidth - 240, $GuiHeight - 10, $ES_READONLY + $ES_MULTILINE + $ES_AUTOVSCROLL + $WS_VSCROLL)
GUICtrlSetFont($iMemo, 9, 400, 0, "Courier New")
GUICtrlSetData($iMemo, "(" & _Now() & ") Initializing..." & @CRLF, 2)
GUISetState(@SW_SHOW, $GUI)

$c=0;for my testing
Do;you probably want thist to be While 1
    $count=_GUICtrlEdit_GetLineCount($iMemo)
    If $count>=10 Then ;change this to 4096, or whatever line limit you want to set it too. This will check when your control is at limit
        $file=FileOpen(@TempDir & "\Temp_file.txt",2)
        FileWrite($file,GUICtrlRead($iMemo))
        FileClose($file)
        $line=FileReadLine(@TempDir & "\Temp_file.txt",2) 
        $iMsg=$line & @CRLF
        For $i=3 to $count-1 
            $line=FileReadLine(@TempDir & "\Temp_file.txt",$i)
            $iMsg=$iMsg & $line & @CRLF
        Next
        GUICtrlSetData($iMemo, $iMsg);this will reset your edit, and skipping line 1 otherwise deleteing it.
    EndIf
    GUICtrlSetData($iMemo, "(" & _Now() & ") Initializing..." & @CRLF,2);your function to add another line
    $c+=1;for my testing purpose
Until $c=20;Wend

While 1
    Sleep(100)
WEnd

This should work:

...
$iMemo = GUICtrlCreateEdit("",245, 5, $GUIWidth - 240, $GuiHeight - 10, $ES_READONLY + $ES_MULTILINE + $ES_AUTOVSCROLL + $WS_VSCROLL)
GUICtrlSetLimit(-1, 0x7FFFFFFF)
...

You rock. I will give it a run, and we'll see in a couple days if it works. Is there anything else I need to worry about? In 60 days is my script going to crash cause its so large? I don't understand the 0x7FFFFFFF hex number. I tried to google it, and apparently we're going to die in 2038 cause of that number. =)
