GUIListViewEx - BugFix Version 6 Apr 24

[CodeWriter]

@Melba23Thank you for the reply. I’m just starting to learn your UDF and spent most of yesterday puzzled why the header coloring didn’t work as expected, even in the Example codes.

Tried numerous combinations without success, read and re-read the function definitions, rtf guide, and examples. So reached out to you to see if I had some basic misunderstanding of that function.

After I had commented, I found the recent posts where this issue was gradually uncovered by @borsTiHD and yourself. Wary of what other functionality is quietly not working as expected.

Running the code compiled in x86 mode is possible for now but writing code, debugging and testing in the interpreter is a hiccup.

Nothing as far as I know!

Here’s another quirk  with some sample code, adapted straight from your examples. The code snipet below creates a listview with 4 columns and populates them from an array[n][4]. Except for a different array name and GUI sizes, the exact same code runs without error using a listview with 2 columns and array[n][2].

; Create GUI:
    Local $hMacroGUI, $vData, $hMacro, $iEditMode = 0, $bEdited = False
    $hMacroGUI = GUICreate("Active Macros", 1520, 945, 25, 990)

    ; Create ListView using GUICtrlListViewEx.au3 UDF:
    $hMacro = _GUICtrlListView_Create($hMacroGUI, "", 5, 5, 1510, 890, BitOR($LVS_DEFAULT, $WS_BORDER))
    _GUICtrlListView_SetExtendedListViewStyle($hMacro, $LVS_EX_FULLROWSELECT)
    _GUICtrlListView_AddColumn($hMacro, "Column1", 200)
    _GUICtrlListView_AddColumn($hMacro, "Column2", 250)
    _GUICtrlListView_AddColumn($hMacro, "Column3", 400)
    _GUICtrlListView_AddColumn($hMacro, "Column4", 3000)

    ; Set font:
    Local $hFont = _WinAPI_CreateFont(19, 7, 0, 0, $FW_NORMAL, False, False, False, $DEFAULT_CHARSET, _
            $OUT_DEFAULT_PRECIS, $CLIP_DEFAULT_PRECIS, $DEFAULT_QUALITY, 0, "Helvetica")
    _WinAPI_SetFont($hMacro, $hFont, True)

    ; Populate the ListView:
    Local $limit = UBound($Gmacro) - 1
    For $i = 0 To $limit
        _GUICtrlListView_AddItem($hMacro, $Gmacro[$i][0])
        _GUICtrlListView_AddSubItem($hMacro, $i, $Gmacro[$i][1], 1)
        _GUICtrlListView_AddSubItem($hMacro, $i, $Gmacro[$i][2], 2)
        _GUICtrlListView_AddSubItem($hMacro, $i, $Gmacro[$i][3], 3)
    Next

    ; Initialize the GUIListViewEx UDF: (16: enable color header, 32: user colored items)
    Local $iLV = _GUIListViewEx_Init($hMacro, $Gmacro, 0, 0xFF0000, True, 16 + 32)

when execution reaches the last line

Local $iLV = _GUIListViewEx_Init($hMacro, $Gmacro, 0, 0xFF0000, True, 16 + 32)

it results in the following error:

"C:\Users\...\GUIListViewEx.au3" (517) : ==> Array variable has incorrect number of subscripts or subscript dimension range exceeded.:
$aLVArray[$i + $iStart][$j - 1] = $aRow[$j]
^ ERROR

I have also tried  reading the array into the UDF before initialization with the following line but it fails with the same error  from _GUIListViewEx_ReadToArray():

$aLV_List = _GUIListViewEx_ReadToArray($hMacro, 0)

Stranger still, if you simply comment out column 4 and the corresponding line populating the listview in the For loop, it works without error for a 3-column display. I don't know if this is related in some way to the same 64-bit issue but it also fails when I compile the code in x86 mode.

A separate issue is that string data in my array[n][4] can be 2000 chars long but only about 265 chars are displayed before being truncated in the listview.

CodeWriter,

I have added a few lines to your snippet so it runs (please post runnable code in future) and it loads a 4x4 array with no problems:

expandcollapse popup

#include <GUIConstantsEx.au3>
#include <WindowsConstants.au3>
#include <WinAPIGdi.au3>
#include <FontConstants.au3>

#include "GUIListViewEx.au3"

Global $Gmacro[4][4] =[[1,2,3,4],[5,6,7,8],["a","b","c","d"],["w","x","y","z"]]

; Create GUI:
    Local $hMacroGUI, $vData, $hMacro, $iEditMode = 0, $bEdited = False
    $hMacroGUI = GUICreate("Active Macros", 1520, 945, 25, 25)

    ; Create ListView using GUICtrlListViewEx.au3 UDF:
    $hMacro = _GUICtrlListView_Create($hMacroGUI, "", 5, 5, 1510, 890, BitOR($LVS_DEFAULT, $WS_BORDER))
    _GUICtrlListView_SetExtendedListViewStyle($hMacro, $LVS_EX_FULLROWSELECT)
    _GUICtrlListView_AddColumn($hMacro, "Column1", 200)
    _GUICtrlListView_AddColumn($hMacro, "Column2", 250)
    _GUICtrlListView_AddColumn($hMacro, "Column3", 400)
    _GUICtrlListView_AddColumn($hMacro, "Column4", 3000)

    ; Set font:
    Local $hFont = _WinAPI_CreateFont(19, 7, 0, 0, $FW_NORMAL, False, False, False, $DEFAULT_CHARSET, _
           $OUT_DEFAULT_PRECIS, $CLIP_DEFAULT_PRECIS, $DEFAULT_QUALITY, 0, "Helvetica")
    _WinAPI_SetFont($hMacro, $hFont, True)

    ; Populate the ListView:
    Local $limit = UBound($Gmacro) - 1
    For $i = 0 To $limit
        _GUICtrlListView_AddItem($hMacro, $Gmacro[$i][0])
        _GUICtrlListView_AddSubItem($hMacro, $i, $Gmacro[$i][1], 1)
        _GUICtrlListView_AddSubItem($hMacro, $i, $Gmacro[$i][2], 2)
        _GUICtrlListView_AddSubItem($hMacro, $i, $Gmacro[$i][3], 3)
    Next

    ; Initialize the GUIListViewEx UDF: (16: enable color header, 32: user colored items)
    Local $iLV = _GUIListViewEx_Init($hMacro, $Gmacro, 0, 0xFF0000, True, 16 + 32)

    GUISetState()

While 1

    Switch GUIGetMsg()
        Case $GUI_EVENT_CLOSE
            Exit
    EndSwitch

WEnd

@Melba23Your example helped me to find the core issue which is the data in my array. The 4th column is populated by a 2000-3000 character string that contains UTF-8 characters. When I replace that with ASCII characters in a test, there is no error from _GUIListViewEx_Init() or_GUIListViewEx_ReadToArray(). Without the ability to use UTF-8 and the standard ListView limiting the data cells to about 265 chars, I will work on another approach. Thank you for your help.

[Melba23]

CodeWriter,

Sorry to hear that - but glad it was not my UDF at fault!

[CodeWriter]

While the standard ListView and GUIListView.au3 functions can handle UTF-8 characters, something in your UDF functions _GUIListViewEx_Init() and_GUIListViewEx_ReadToArray() is unable to process those characters and throws an error.

CodeWriter,

Can you let me have a copy of some of the data you are trying to insert so that I can have a play and see if I can come up with a solution - via PM if you do not want to post in open forum.

All,

The problem was that the data contained the default Data Separation Character ("|") which the UDF (and AutoIt) was interpreting as a column delimiter. The solution was to change the default separator character using Opt.
