#235 No Bug _GUICtrlListView_AddItem() VS GUICtrlCreateListViewItem() + Fix. Shlomikalfa@…
Description

Issues: -> UDF - doesn't support Unicode. [But works smooth with no flicker.] -> Built-in - Flickers like a disco light , Re'draws the listview i think. [But support Unicode just fine!]

Please review the following topic as there is a UDF replied by one of the forum members which Combines both the benefits of the above, it doesn't flicker and it does support Unicode.

This is my first bug-report, hope i've done it right. LOVE YOU ALL !!!!!

#243 No Bug ListView control on Tab and WM_NOTIFY Event error + reproduction. Shlomikalfa@…
Description

[Description]

I have a listview obj, created using the built-in inside a TAB at the 2nd TAB. the items are inserted using a _UDF someone has donated in the forum... it is being monitored by WM_Notify [just like in the help file]. when i click on entry #3, Row #4 of the listview, the TAB always switches to it's first TAB item.

[Reproduction]

#include <GuiConstantsEx.au3>
#include <GuiListView.au3>
#include <GuiImageList.au3>
#include <WindowsConstants.au3>
Opt("GUIOnEventMode", 1)
