_GUICtrlListView_GetItemTextString() --> BIG speed optimize
| Reported by: | Zedna | Owned by: | Jpm |

Description
$iSelected = _GUICtrlListView_GetNextItem($hWnd)
should be before FOR NEXT loop and not inside.
When I need to get text of all listview items then this function will be called many times: number of rows * number of columns!
original:
Func _GUICtrlListView_GetItemTextString($hWnd, $iItem = -1)
If $Debug_LV Then _GUICtrlListView_ValidateClassName($hWnd)
Local $sRow = "", $SeparatorChar = Opt('GUIDataSeparatorChar')
If $iItem <> -1 Then ; get row
For $x = 0 To _GUICtrlListView_GetColumnCount($hWnd) - 1
$sRow &= _GUICtrlListView_GetItemText($hWnd, $iItem, $x) & $SeparatorChar
Next
Return StringTrimRight($sRow, 1)
Else ; get current row selected
For $x = 0 To _GUICtrlListView_GetColumnCount($hWnd) - 1
$sRow &= _GUICtrlListView_GetItemText($hWnd, _GUICtrlListView_GetNextItem($hWnd), $x) & $SeparatorChar
Next
Return StringTrimRight($sRow, 1)
EndIf
EndFunc ;==>_GUICtrlListView_GetItemTextString
optimized:
Func _GUICtrlListView_GetItemTextString($hWnd, $iItem = -1)
If $Debug_LV Then _GUICtrlListView_ValidateClassName($hWnd)
Local $sRow = "", $SeparatorChar = Opt('GUIDataSeparatorChar')
If $iItem <> -1 Then ; get row
For $x = 0 To _GUICtrlListView_GetColumnCount($hWnd) - 1
$sRow &= _GUICtrlListView_GetItemText($hWnd, $iItem, $x) & $SeparatorChar
Next
Return StringTrimRight($sRow, 1)
Else ; get current row selected
$iSelected = _GUICtrlListView_GetNextItem($hWnd)
For $x = 0 To _GUICtrlListView_GetColumnCount($hWnd) - 1
$sRow &= _GUICtrlListView_GetItemText($hWnd, $iSelected, $x) & $SeparatorChar
Next
Return StringTrimRight($sRow, 1)
EndIf
EndFunc ;==>_GUICtrlListView_GetItemTextString
