I was reading the Helpfile on both GUICtrlRegisterListViewSort and _GUICtrlListView_SimpleSort, and after running my script, I was initially satisfied with the way columns are sorted when the user clicks on the column header.

But at certain occasions, clicking on the column header to sort numbers - integers in particular - seem to have some unexpected behaviour.

I cannot verify if it is due to the way I wrote the script, or because the functions used in AutoIt to sort numbers intentionally work the way they do.

Example:

Column ID | Item ID | Item Name | Date

1 | ID_1 | One | 14/05/2014

2 | ID_2 | Two| 14/05/2014

3 | ID_3 | Three| 14/05/2014

10 | ID_4 | Four| 14/05/2014

9 | ID_5 | Five| 14/05/2014

27 | ID_6 | Siz| 15/05/2014

When the user clicks Column ID, logically the order of ascending sorting would look like this:

1, 2, 3, 9, 10, 27

But what I got is like this:

1, 10, 2, 27, 3, 9

Does anyone know the reason behind the way it is sorted this way?

How then do I get the columns to be sorted correctly when the user clicks the column header?

(I did read across other related threads like  and )

I attached my codes here to see if I might write them wrongly.

My code for generating ListView:

$inventoryList = GUICtrlCreateListView("ID|item id|item name| Date", 45, 140, expandGUIX(750), expandGUIY(450), $LVS_REPORT, BitOR($LVS_EX_FULLROWSELECT, $WS_EX_CLIENTEDGE))
_GUICtrlListView_SetColumnWidth(-1, 3, 651)
$hInventoryList = GUICtrlGetHandle($inventoryList)
For $i = 0 To 3
    _GUICtrlListView_SetColumnWidth($inventoryList, $i, $LVSCW_AUTOSIZE_USEHEADER)
Next

My code for auto-resizing columns:

Func resizeColumns($hWnd, $listView, $iColumns, $iGUI_Width, $iGUI_Height)
    ; Check top index - if not 0 then we have a scroll bar so increase ListView width
    Local $iScroll_Allowance
    If _GUICtrlListView_GetTopIndex($listView) > 0 Then
        $iScroll_Allowance = 17
    EndIf

    ; Determine ListView width
    Local $iLV_Width = $iScroll_Allowance
    Local $iData_Width, $iHeader_Width
    Local $i = 0
    For $i = 0 To $iColumns - 1
        ; Size column to fit header
        _GUICtrlListView_SetColumnWidth($listView, $i, $LVSCW_AUTOSIZE_USEHEADER)
        $iHeader_Width = _GUICtrlListView_GetColumnWidth($listView, $i)
        ; Now size column to fit data
        _GUICtrlListView_SetColumnWidth($listView, $i, $LVSCW_AUTOSIZE)
        $iData_Width = _GUICtrlListView_GetColumnWidth($listView, $i)
        ; If header is wider, reset width
        If $iHeader_Width > $iData_Width Then
            _GUICtrlListView_SetColumnWidth($listView, $i, $iHeader_Width)
            $iLV_Width += $iHeader_Width
        Else
            $iLV_Width += $iData_Width
        EndIf
    Next

    ; Resize ListView and GUI to fit data
    ControlMove($hWnd, "", $listView, 10, 10, $iLV_Width + 10, $iGUI_Height - 20) ; Add 10 for internal ListView borders
EndFunc   ;==>resizeColumns

My code for locking users from resizing columns after auto-resize:

Func _WM_NOTIFY($hWnd, $iMsg, $wParam, $lParam)
    #forceref $hWnd, $iMsg, $wParam

    ; Get details of message
    Local $tNMHEADER = DllStructCreate($tagNMHEADER, $lParam)
    ; Look for header resize code
    $iCode = DllStructGetData($tNMHEADER, "Code")
    Switch $iCode
        Case $HDN_BEGINTRACKW
            ; Prevent resizing
            Return True
        Case $LVN_COLUMNCLICK
            ; Sort column
            $tInfo = DllStructCreate($tagNMLISTVIEW, $lParam)
            $iCol = DllStructGetData($tInfo, "SubItem")
            _GUICtrlListView_SimpleSort($cListView, $g_bSortSense, $iCol)
    EndSwitch

    Return $__LISTVIEWCONSTANT_GUI_RUNDEFMSG
EndFunc   ;==>_WM_NOTIFY

It's called a lexical or lexicographical sort, it sorts by the character values, not the numeric values.


If I posted any code, assume that code was written using the latest release version unless stated otherwise. Also, if it doesn't work on XP I can't help with that because I don't have access to XP, and I'm not going to.

Hi BrewManNH,

Thanks for the tip. I just did a search on the forums and came across this thread that's related to lexical sort ('?do=embed' frameborder='0' data-embedContent>>).

(Gonna add 'lexical' to my vocab, sounds new to me ._. )

Not sure of how to integrate the UDF (shown inside the link) into a ListView sort, since the link I shared is for sorting arrays instead of ListView.

Any ideas or has anyone else did proper number sorting before for ListView?

      I am tracking this topic by @LarsJ.  It is very advanced and overkill for what I am currently trying to do.
       
      Problem is this.
      Listview contains columns, one of which is right aligned and gets populated by float values, such as 123.99.  Some do not have decimals ie 124.00 and on sort gets truncated to 124.  Its obviously still the same value, but the display has reset.
      ; line below is for list VIEW ;..................................0.........1......2............ $cListView = GUICtrlCreateListView("CUSTOMER|AMOUNT|DESCRIPTION", 8, 152, 764, 279) GUICtrlSetBkColor($cListView, $GUI_BKCOLOR_LV_ALTERNATE) ; alternate between the listview background color and the listview item background color GUICtrlSetBkColor($cListView, $LVStdClr) ; Set the background color for the listview _GUICtrlListView_SetColumnWidth($cListView, 0, 120) ; -- the client name _GUICtrlListView_SetColumnWidth($cListView, 1, 90) ;-- the amount _GUICtrlListView_JustifyColumn($cListView, 1, 1) ; 1 - Text is right aligned _GUICtrlListView_SetColumnWidth($cListView, 2, 200) ; the description What I am looking for is something native and simple like a 
          _GUICtrlListView_SetColumnFormat($cListView, 1, "%.2f") ;  1 - column is stringformatted to "%.2f"
      So that after each sort it will appear as it was in the original rendering.
      Is there something like this? I have not been able to find a simple solution.

      Thanks.
