ListView: deleting top-so many rows

[ycomp]

Hi, how can I delete the top 'x' rows of a list view... or actually what I want to do is to keep the bottom, let's say, 500 rows and delete all above it.

I wrote a crude debugging console using a listview and I'm worried about it consuming a huge amount of memory over a long period of time. So I'd like to only display the last 500 rows most of the time.

p.s. this is unrelated to my other listview question about memory leaks that was answered. That one is a different type of app.

Can't you use _GUICtrlListView_DeleteItem?

I am really new to this autoit listview stuff... how do I retrieve the row for a list view item?

also, is there no comand to delete an entire row?

also, I noticed a _GUICtrlListView_DeleteItemsSelected command... would it be faster to select items and then delete using this command, or will it be same speed as _GUICtrlListView_DeleteItem? (i would turn off updating before using either method)

An Item is a "Row".

If you created the Item(s) using the GuiCtrlCreateListViewItem then you'll need to use GuiCtrlDelete as I showed you in the other thread.

You could get the count then minus 500 from the starting point and work to zero from there on the delete.

ok, thanks for the help.. I implemented that delete already this morning for the other project as you suggested.

now it's coming back to... starting to remember from my delphi days.. there is an item with a bunch of subitems. Easier than I thought, I was thinking each item was a cell... forgot I was adding the "cells" using those separator chars

didn't really think before... i think it might be easier to when adding a new line, check the # of rows, then if it is exceeded to delete the first item.
