Why blocking of WM_NOTIFY is worse than blocking in a main loop?

Try with _ArrayDisplay. Create a temporary array in that message function and then you will see what happens.

I will have to look for the problem _ArrayDisplay

The function "_ArrayDisplay" creates a window. I in the example don't create a window. Therefore the problem of the _ArrayDisplay function is an exception, which in my case not a hindrance.

Normally when the Devs say "we don't recommend this" it's normally best to listen and take note.

UDF List:

I had problems when catching/using several messages in WM_NOTIFY with blocking code.

There were some visual problems or even crashes.

Another type of problems was with timing in my functions invoked from WM_NOTIFY (directly),

when I tried to get some GUI properties it had bad value because internal code from WM_NOTIFY wasn't finished.

These type of problems is related on length (time consuming) of your blocking code

so it's dangerous to ignore recommendations a do it by risky way.

Why do I need to do a mediator who will redirect actions to a main loop?

Yes, I tested an example with it but there is a bug I can't explain. There is nothing related to it in the bugtracker nor in the forum or in the helpfile.

As you will see, the data of the structure is not the same in WM_NOTIFY and _MyFunc1 functions.

#include <GUIConstantsEx.au3>
#include <WindowsConstants.au3>
#include <GuiListView.au3>

Opt("GUIOnEventMode", 1)

Global $iListView, $hListView

Global $_tInfo = 0, $blCallFunc1 = False

$hGUI = GUICreate('', 450, 360)
GUISetOnEvent($GUI_EVENT_CLOSE, '_Exit')
$iListView = GUICtrlCreateListView('Col 1', 5, 5, 440, 330, BitOR($GUI_SS_DEFAULT_LISTVIEW, $LVS_REPORT, $LVS_SHOWSELALWAYS))
$hListView = GUICtrlGetHandle(-1)

For $i = 100 To 111
    GUICtrlCreateListViewItem($i, $iListView)
Next

GUISetState()
GUIRegisterMsg($WM_NOTIFY, "WM_NOTIFY")

While 1
    Sleep(10)
    If $blCallFunc1 Then
        $blCallFunc1 = False
        _MyFunc1()
    EndIf
WEnd

Func _MyFunc1()
    ConsoleWrite("_MyFunc1 Index: " & DllStructGetData($_tInfo, "Index") & @crlf)
    MsgBox(0, 'Blocking', _GUICtrlListView_GetItemText($hListView, DllStructGetData($_tInfo, "Index"), DllStructGetData($_tInfo, "SubItem")), 0, $hGUI)
EndFunc   ;==>_MyFunc1

Func WM_NOTIFY($hWnd, $iMsg, $iwParam, $ilParam)
    Local $hWndFrom, $iIDFrom, $iCode, $tNMHDR
    $tNMHDR = DllStructCreate($tagNMHDR, $ilParam)
    $hWndFrom = HWnd(DllStructGetData($tNMHDR, "hWndFrom"))
    $iIDFrom = DllStructGetData($tNMHDR, "IDFrom")
    $iCode = DllStructGetData($tNMHDR, "Code")
    Switch $hWndFrom
        Case $hListView
            Switch $iCode
                Case $NM_CLICK
                    $_tInfo = DllStructCreate($tagNMITEMACTIVATE, $ilParam)
                    ConsoleWrite("WM_NOTIFY Index: " & DllStructGetData($_tInfo, "Index") & @crlf)
                    $blCallFunc1 = True
            EndSwitch
    EndSwitch
    Return $GUI_RUNDEFMSG
EndFunc   ;==>WM_NOTIFY

Func _Exit()
    Exit
EndFunc   ;==>_Exit
Edit: Added indents.

Note: I never used DllStructGetData (as far as I can remember) in different functions so I don't know if I'm using it badly or whatever.

Br, FireFox.

Do it this way:

Func _MyFunc1()
;~     ConsoleWrite("_MyFunc1 Index: " & DllStructGetData($_tInfo, "Index") & @crlf)
    ConsoleWrite("_MyFunc1 Index: " & _GUICtrlListView_GetNextItem($hListView)  & @crlf)
;    MsgBox(0, 'Blocking', _GUICtrlListView_GetItemText($hListView, DllStructGetData($_tInfo, "Index"), DllStructGetData($_tInfo, "SubItem")), 0, $hGUI)
EndFunc   ;==>_MyFunc1

Or make $index/$subitem as global variables

or use SendMessage() with $index/$subitem parameters as described in my original topic here
