[SOLVED]_Sorting listview Column.

goldenix · June 12, 2008

EDIT: Original Q Was How to sort a Listview Column by Calling a function like:

_ListView_Sort(2) ; Sort Column 2

if you are facing the same Problem dont bother to look into the help file(its a waist of time!), the solution is hire:

Bump*

I stripped the code to: But its not sorting properly now..Any Ideas Why?

Global $B_DESCENDING[_GUICtrlListView_GetColumnCount($hListView)]

Func _a()
    $tInfo = DllStructCreate($tagNMLISTVIEW)
     _GUICtrlListView_SimpleSort(GUICtrlGetHandle($hListView), $B_DESCENDING, DllStructGetData($tInfo, "SubItem"))
EndFunc
 
_a()

In my Email_zak & Log_View projects (see my signature) I use:

GUICtrlRegisterListViewSort($ListView1, "LVSort")

Func LVSort($hWnd, $nItem1, $nItem2, $nColumn)
    If $nColumn = 0 Then ; Zakaznik
        $val1 = GetSubItemText($ListView1, $nItem1, $nColumn)
        $val2 = GetSubItemText($ListView1, $nItem2, $nColumn)
                $nResult = 0 ; No change of item1 and item2 positions

        If $val1 < $val2 Then
            $nResult = -1  ; Put item2 before item1
        ElseIf  $val1 > $val2 Then
            $nResult = 1   ; Put item2 behind item1
        EndIf
                Return $nResult
    Else ; do nothing when clicked on header at other columns
        Return 0 ; No change of item1 and item2 positions
    EndIf
EndFunc

Func GetSubItemText($nCtrlID, $nItemID, $nColumn)
    Local $stLvfi       = DllStructCreate("uint;ptr;int;int[2];int")
    DllStructSetData($stLvfi, 1, $LVFI_PARAM)
    DllStructSetData($stLvfi, 3, $nItemID)

    Local $stBuffer     = DllStructCreate("char[260]")
    $nIndex = GUICtrlSendMsg($nCtrlID, $LVM_FINDITEM, -1, DllStructGetPtr($stLvfi))

    Local $stLvi        = DllStructCreate("uint;int;int;uint;uint;ptr;int;int;int;int")
    DllStructSetData($stLvi, 1, $LVIF_TEXT)
    DllStructSetData($stLvi, 2, $nIndex)
    DllStructSetData($stLvi, 3, $nColumn)
    DllStructSetData($stLvi, 6, DllStructGetPtr($stBuffer))
    DllStructSetData($stLvi, 7, 260)

    GUICtrlSendMsg($nCtrlID, $LVM_GETITEM, 0, DllStructGetPtr($stLvi));

    $sItemText  = DllStructGetData($stBuffer, 1)
    $stLvi = 0
    $stLvfi = 0
    $stBuffer = 0

    Return $sItemText
EndFunc

Func DoSort()
    ; sort by first column
    $struct_NMLISTVIEW = DllStructCreate("hwnd;uint;uint;int;int;uint;uint;uint;int;int;int")
    DllStructSetData($struct_NMLISTVIEW,1,GUICtrlGetHandle($ListView1))
    DllStructSetData($struct_NMLISTVIEW,2,$ListView1)
    DllStructSetData($struct_NMLISTVIEW,3,$LVN_COLUMNCLICK)
    DllStructSetData($struct_NMLISTVIEW,4,-1) ; item = -1
    DllStructSetData($struct_NMLISTVIEW,5,0) ; subitem=0

    _SendMessage($Form1, $WM_NOTIFY, $ListView1, DllStructGetPtr($struct_NMLISTVIEW))
    $struct_NMLISTVIEW = 0
EndFunc

Just call DoSort() after you fill up your Listview by data - it simulates click on header of first column.

In my Email_zak & Log_View projects (see my signature) I use: Just call DoSort() after you fill up your Listview by data - it simulates click on header of first column.

Edit, Cant do nothing with ur project files, Getting loads & loads of errors with this latest autoit version. If I find some old versions, ill try looking into ur projects again.

Try Running this: see if you also Get these errors?

About errors: Just accomodate list of your include files.

Projects in my signature are older so take it as concept ideas and not as "exact solution" for latest AutoIt.

But you can't use _GUICtrlListView_Create() if you wish to use GUICtrlRegisterListViewSort()

You must use GUICtrlCreateListView()

See a _GUICtrlListView_SortItems() function in the help file.

See a _GUICtrlListView_SortItems() function in the help file.

If the help file Sorting example would be as simple as calling this to perform the sort:

_GUICtrlListView_SimpleSort($listview, 'Descending', $Column = 1)

Then I wouldnt be asking.

Im back to autoit ver 3.2.10 & still No nothing works. Can explain how can I write this:

GUIRegisterMsg($WM_NOTIFY, "WM_NOTIFY")
