Zohran,

I would do it like this: ;)

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

$hGUI = GUICreate("Test", 500, 500)

$cLV = GUICtrlCreateListView("Item|SubItem", 10, 10, 480, 105)
_GUICtrlListView_SetColumnWidth($cLV, 0, 200)
_GUICtrlListView_SetColumnWidth($cLV, 1, 250)

For $i = 0 To 30
    GUICtrlCreateListViewItem("Item " & $i & "|SubItem " & $i, $cLV)
Next

; Find out how many items will fit vertically
$iCount = _GUICtrlListView_GetCounterPage($cLV)

$cButton = GUICtrlCreateButton("Visible?", 10, 300, 80, 30)

GUISetState()

While 1

    Switch GUIGetMsg()
        Case $GUI_EVENT_CLOSE
            Exit
        Case $cButton
            ; Find the top index
            $iTop = _GUICtrlListView_GetTopIndex($cLV)
            ; And so the bottom must be
            $iBottom = $iTop + $iCount - 1
            ; And announce the result
            MsgBox(0, "Visible", "Items " & $iTop & " to " & $iBottom)
    EndSwitch

WEnd

All clear? :)

Dear Melba It is not working for icon view.

Zohran,

Why did you not say that your ListView was in icon view? Am I supposed to be mind reader as well? :huh:

Give me a while and I will see what I can come up with. ;)

Zohran,

That was harder than I thought it would be - this is as far as I have got: :sweating:

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

$hGUI = GUICreate("LV", 400, 300)

$iLV_Width = 380
$iLV_Ht = 230
$iSpace_H = 50
$iSpace_V = 25

$cLV = GUICtrlCreateListView("", 10, 10, $iLV_Width, $iLV_Ht, BitOR($LVS_ICON, $LVS_ALIGNLEFT))

_GUICtrlListView_SetView($cLV, 1)

$hImageList = _GUIImageList_Create(32, 32, 5, 4, 3)
_GUIImageList_AddIcon($hImageList, @SystemDir & "shell32.dll", 110, True)
_GUIImageList_AddIcon($hImageList, @SystemDir & "shell32.dll", 131, True)
_GUIImageList_AddIcon($hImageList, @SystemDir & "shell32.dll", 165, True)
_GUICtrlListView_SetImageList($cLV, $hImageList, 0)

_GUICtrlListView_SetIconSpacing($cLV, $iSpace_H, $iSpace_V)

$cButton = GUICtrlCreateButton("Visible?", 10, 250, 80, 30)

; Add items
For $i = 0 To 49
    _GUICtrlListView_AddItem($cLV, "Icon " & $i, Random(0, 2, 1))
Next

$iTopLeft = _GUICtrlListView_FindNearest($cLV, 25, 25)
$iBotLeft = _GUICtrlListView_FindNearest($cLV, 25, $iLV_Ht - 25, 2)
$iTopRt = _GUICtrlListView_FindNearest($cLV, $iLV_Width, 0, 0)
$iDown = $iBotLeft - $iTopLeft + 1
$iAcross = Int($iTopRt / $iDown)
$iNumVis = $iAcross * $iDown

GUISetState()

While 1

    Switch GUIGetMsg()
        Case $GUI_EVENT_CLOSE
            _GUIImageList_Destroy($hImageList)
            Exit
        Case $cButton
            $iTopLeft = _GUICtrlListView_FindNearest($cLV, $iSpace_H / 2, $iSpace_V / 2)
            $iEnd = $iTopLeft + $iNumVis - 1
            MsgBox(0, "Visible", "Items " & $iTopLeft & " to " & $iEnd)
    EndSwitch

WEnd

I will see if I can come up with something better. :)

Not very accurate.Its a good effort.

Zohran,

You are welcome - I will look again at the code after dinner. :)

But I know what I wrote - in future could you please use the "Reply to this topic" button at the top of the thread or the "Reply to this topic" editor at the bottom rather than the "Quote" button. Requoting the previous post just pads the thread unneccessarily. ;)

Zohran,

:sweating:

This is confusing.

I quite agree, but trancexx is entitled to her opinion - and in this matter, as in so many others, she and I have opposing views. You will have to decide for yourself which of us is correct - but there is no need to state it here. :)

Edit: Just seen your "not very accurate" comment concerning the code I posted earlier - I realise that and I will see what I can do to improve it. Does the ListView at least look like the one you want to use? :huh:

Zohran,

Further testing has shown the _GUICtrlListView_FindNearest to be very inaccurate - it is extremely sensitive to very snall changes of position within the ListView and you often get a result you do not expect. :(

I will have a think about another approach. ;)
