GUICtrlCreateListView Limits?

[inov8iv]

GUICtrlCreateListView apparently has a limit of lines which can be put into listview. I looked at the help file and could not find the limit nor could I find how to extend the limit. I have a file with 7000 lines I want to import/edit/save. I also need help with Editing the data and saving the final product.

Input File is INI and formatted Like below for 7,000+ Lines:

[Parts]

2" Muffler Extension=1.59,2.59,3.09,5.09

etc.....

This is the code I currently have.

expandcollapse popup

#include <GUIConstants.au3>
#include <GuiListView.au3>

$iFile= @ScriptDir & "\Test.ini"
$oFile = @ScriptDir & "\Test.tmp"
$i = 1

GUICreate("Price Editor", 420, 500)
GUISetBkColor (0xE0FFFF)  

$ListView = GUICtrlCreateListView("Part Name|BP Blk|BP Chr|SP Blk|SP Chr", 8, 36, 404, 414, BitOR($LVS_SINGLESEL, $LVS_SHOWSELALWAYS, $LVS_EDITLABELS))
$button = GUICtrlCreateButton ("Exit",8, 8, 70, 20)
$B_Search = GUICtrlCreateButton("Search", 88, 8, 70, 20)

GUISetState()

$iPut=FileOpen($iFile, 0)
$oPut=FileOpen($oFile, 2)

While $i <> 0
    $iLine = FileReadLine($iPut)
    If StringInStr($iLine, "[Parts]") Then $iLine = FileReadLine($iPut)
    $iLine = StringReplace($iLine, "=", "|")
    $iLine = StringReplace($iLine, ",", "|")
    _GUICtrlListViewInsertItem($ListView, -1, $iLine) ;==> Changed due to MsCreatoR's suggestion now it loads the entire file;)
    If StringInStr($iLine, "|") Then 
        $i = 1
    Else 
        $i = 0
    EndIf
WEnd
_GUICtrlListViewSetColumnWidth($ListView, 0, 182)
_GUICtrlListViewSetColumnWidth($ListView, 1, 50)
_GUICtrlListViewSetColumnWidth($ListView, 2, 50)
_GUICtrlListViewSetColumnWidth($ListView, 3, 50)
_GUICtrlListViewSetColumnWidth($ListView, 4, 50)

Do
  $msg = GUIGetMsg()
   Select
      Case $msg = $button
         FileClose($iFile)
        FileClose($oFile)
        Exit
    Case $msg = $B_Search
    ;Still working on this portion
   EndSelect
Until $msg = $GUI_EVENT_CLOSE

Any suggestions or comments are appreciated.

Hi,

From the help file:

15. What are the current technical limits of AutoIt v3?

Here are details of the current technical limits of AutoIt. Please note that some of the limits are theoretical and you may run into performance or memory related problems before you reach the actual limit.

Maximum length of a single script line: 4,095

Maximum string length: 2,147,483,647 characters

Number range (floating point): 1.7E–308 to 1.7E+308 with 15-digit precision

Number range (integers): 64-bit signed integer

Hexadecimal numbers: 32-bit signed integer (0x80000000 to 0x7FFFFFFF)

Arrays: A maximum of 64 dimensions and/or a total of 16 million elements

Maximum depth of recursive function calls: 384 levels

Maximum number of variables in use at one time: No limit

Maximum number of user defined functions: No limit

Maximum number of GUI windows: 1024

Maximum number of GUI controls per window: 4096

Each GUICtrlCreateListViewItem is a control, so when it reached the 4096 creations it stops to create... look for solution here on forum by keywords like _GUICtrlListViewInsertItem

Well I have been searching on here and in the help file for the past 5 hours, figured I could ask after that much effort.

Thank you that solved Problem #1, now any suggestions on how to EDIT / SAVE? Just point me in the right direction and I can get it from there.

any suggestions on how to EDIT / SAVE?

What you mean? edit list view items? look for _GUICtrlListViewSetItemText() in the help file (under UDF section).
