Custom Query

Hi,

#include <Array.au3>
$r = StringSplit('a,u,t,o,i,t, , a, a', ',')
ConsoleWrite(_ArrayToString($r, ' ') & @CRLF)
$r = _ArrayUnique($r)
ConsoleWrite(_ArrayToString($r, ' ') & @CRLF)

Output is:

9 a u t o i t    a  a
8 9 a u t o i    a

There is also a typo in the helpfile : 2x containing Success: Returns a 1-dimensional array containing containing only the unique elements of that Dimension

If an array containing empty elements is saved by _FileWriteFromArray, it can no longer be read by _FileReadToArray, which returns error 2 "cannot split file".

I track whether certain files listed in an array have already been accessed by creating a shadow array of the same size and setting its elements to 1 when the corresponding file in the first array is accessed. The shadow array is then saved on exit using _FileWriteFromArray. On startup I load the shadow file and compare its size to the array created from the files on disk as a form of checksum. Under 3.3.0.0 the shadow array, which contains a great number of empty elements (ie long strings of 0x0D0A interspersed with the odd 1), will not load as an array. I have substituted the "old" _FileReadToArray UDF from 3.2.12.1 and the file loads to an array without problem.

Creating the array and then setting all elements to 0 in a loop does enable the "new" _FileReadToArray UDF from 3.3.0.0 to read the array, so the problem does appear to be with the empty elements.

$iSelected = _GUICtrlListView_GetNextItem($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
