Problems with selecting in CtrlListView

[KVasya]

Hello.

Have question.

Why

#Include <GuiListView.au3>

    For $i=1 To $iIterationNumber
        $RightTopFrameHandle = ControlGetHandle("Код Безопасности: Инвентаризация", "", 57045)
        $iIndex = _GUICtrlListView_FindText($RightTopFrameHandle, "rule" & $i)
        _GUICtrlListView_SetItemSelected($RightTopFrameHandle, $iIndex)
    ;_GUICtrlListView_SetItemState($RightTopFrameHandle, $iIndex,$LVIS_SELECTED, $LVIS_SELECTED)
    Next

    Send("{DELETE}")
    Send("{ENTER}")

has different result with

#Include <GuiListView.au3>

    For $i=1 To $iIterationNumber
        $RightTopFrameHandle = ControlGetHandle("Код Безопасности: Инвентаризация", "", 57045)
        $iIndex = _GUICtrlListView_FindText($RightTopFrameHandle, "rule" & $i)
        ;_GUICtrlListView_SetItemSelected($RightTopFrameHandle, $iIndex)
    _GUICtrlListView_SetItemState($RightTopFrameHandle, $iIndex,$LVIS_SELECTED, $LVIS_SELECTED)
    Next

    Send("{DELETE}")
    Send("{ENTER}")

In first case all rules were deleted, but in second case only one...

Russian! Yay!

R u sure that the two functions _GUICtrlListView_SetItemState() and the other one perform the same task/functions? I would guess they call different WINAPI functions.

[KVasya]

Well, _GUICtrlListView_SetItemSelected returns:

_SendMessage($hWnd, $LVM_SETITEMSTATE, $iIndex, $pMemory)

when _GUICtrlListView_SetItemState returns:

_SendMessage($hWnd, $LVM_SETITEMA, 0, $pMemory, 0, "wparam", "ptr")

I just started to learn the programming and sometimes behavior of my code is absolutely unpredictable for me.

Second function seems much more universal, but I can't pick up keys for it.

[dragan]

by keys you mean params?

you can use this script (script requires "dssubcls.dll" file which you can download from here - once you get params you can use them for _SendMessage() function):

p.s. script is example for hooking messages from winamp - for example:

wParam = 40046 and lParam = 0 is PAUSE in winamp,

and when you use:

_SendMessage(WinGetHandle("[CLASS:Winamp v1.x]"), $WM_COMMAND, 40046, 0)

it will send PAUSE to the script - I'm guessing you can do the same for delete/enter in your window, just get the right params, also change $CLASS to match window you want to hook)
