Quick _arraybinarysearch Question.

[Simucal]

Alright, when I do a binary search on an array that has the drive letters of the system on it, why does it give me an Error code #2? How is "c:" out of bounds?

$SystemDrives = DriveGetDrive("Fixed")
_ArraySort($SystemDrives)
_ArrayDisplay( $SystemDrives, "sorted" )
$DriveC = _ArrayBinarySearch ($SystemDrives, "c:")
If Not @error Then
   Msgbox(0,'Entry found',' Index:' & $DriveC)
Else
   Msgbox(0,'Entry Not found',' Error:' & @error)
EndIf

Always get the error code 2.

Parameters

$avArray The 1-dimensional sorted array to search on.

$iKey String or number to search for in the array.

$i_Base Optional: Start Array index for sort, normally set to 0 or 1.

Return Value

Success: Returns the key (index of where item is in the array).

Failure: Returns an empty string.

@Error: 0 = No error.

1 = $avArray isn't an array.

2 = $iKey is out of bounds.

3 = If the item wasn't found in the array.

Skip the first entry of the array because that contains a numeric entry:

#include<array.au3>
$SystemDrives = DriveGetDrive("Fixed")
_ArraySort($SystemDrives,0,1)
_ArrayDisplay( $SystemDrives, "sorted")
$DriveC = _ArrayBinarySearch ($SystemDrives, "c:",1)
If Not @error Then
   Msgbox(0,'Entry found',' Index:' & $DriveC)
Else
   Msgbox(0,'Entry Not found',' Error:' & @error)
EndIf
