poila Posted May 15, 2014 Share Posted May 15, 2014 (edited) 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 Edited May 15, 2014 by poila Link to comment Share on other sites More sharing options...
BrewManNH Posted May 15, 2014 Share Posted May 15, 2014 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.Give a programmer the correct code and he can do his work for a day.

poila Posted May 15, 2014 Author Share Posted May 15, 2014 (edited) 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? Edited May 15, 2014 by poila Link to comment Share on other sites More sharing options...
