Little Bug in _ArrayExtract

Recommended Posts


i found and corrected a little bug in _ArrayExtract. The function is not working correctly with 0-based 2 dim arrays. This is due to the fact that the parameter default is '0' but should be 'Default' - as 0 is a valid option for the function call. Here is my corrected version - if you make use of it - helpfile and function tips have to be adapted.

Func _ArrayExtract(Const ByRef $avArray, $iStart_Row = Default, $iEnd_Row = Default, $iStart_Col = Default, $iEnd_Col = Default)

    If $iStart_Row = Default Then $iStart_Row = 0
    If $iStart_Col = Default Then $iStart_Col = 0
    ;removed as this is not working with 0-based arrays
    ;If $iEnd_Row = Default Then $iEnd_Row = 0
    ;If $iEnd_Col = Default Then $iEnd_Col = 0

    If Not IsArray($avArray) Then Return SetError(1, 0, -1)
    Local $iDim_1 = UBound($avArray, $UBOUND_ROWS) - 1
    If $iEnd_Row = Default Then $iEnd_Row = $iDim_1
    If $iStart_Row < 0 Or $iEnd_Row < 0 Then Return SetError(3, 0, -1)
    If $iStart_Row > $iDim_1 Or $iEnd_Row > $iDim_1 Then Return SetError(3, 0, -1)
    If $iStart_Row > $iEnd_Row Then Return SetError(4, 0, -1)
    Switch UBound($avArray, $UBOUND_DIMENSIONS)
        Case 1
            Local $aRetArray[$iEnd_Row - $iStart_Row + 1]
            For $i = 0 To $iEnd_Row - $iStart_Row
                $aRetArray[$i] = $avArray[$i + $iStart_Row]
            Return $aRetArray
        Case 2
            Local $iDim_2 = UBound($avArray, $UBOUND_COLUMNS) - 1
            If $iEnd_Col = Default Then $iEnd_Col = $iDim_2
            If $iStart_Col < 0 Or $iEnd_Col < 0 Then Return SetError(5, 0, -1)
            If $iStart_Col > $iDim_2 Or $iEnd_Col > $iDim_2 Then Return SetError(5, 0, -1)
            If $iStart_Col > $iEnd_Col Then Return SetError(6, 0, -1)
            If $iStart_Col = $iEnd_Col Then
                Local $aRetArray[$iEnd_Row - $iStart_Row + 1]
                Local $aRetArray[$iEnd_Row - $iStart_Row + 1][$iEnd_Col - $iStart_Col + 1]
            For $i = 0 To $iEnd_Row - $iStart_Row
                For $j = 0 To $iEnd_Col - $iStart_Col
                    If $iStart_Col = $iEnd_Col Then
                        $aRetArray[$i] = $avArray[$i + $iStart_Row][$j + $iStart_Col]
                        $aRetArray[$i][$j] = $avArray[$i + $iStart_Row][$j + $iStart_Col]
            Return $aRetArray
        Case Else
            Return SetError(2, 0, -1)

    Return 1

EndFunc   ;==>_ArrayExtract
