_ArrayMaxIndex doesnt make sense

4 posts in this topic

#include <Array.au3>

Local $aArray[5] = ["", "", "mikejones", "john", ""]
ConsoleWrite(_ArrayMaxIndex($aArray) & @CR)

For $i = 0 To UBound($aArray) - 1
If $aArray[$i] = "" Then ConsoleWrite("blank value at index = " & $i & @CR)
Next

I would expect _ArrayMaxIndex to return a value of 3 considering "john" is the last non blank value in my array of 5 elements. John is at element 3. I am trying to find code that will give me something as simple as... what element in an array is the last non blank value.

This code gives you the index of the highest element with a nonblank value:

For $i = UBound($aArray) - 1 To 0 Step -1
    If $aArray[$i] <> "" Then
        ConsoleWrite("Highest nonblank value at index: " & $i & @CR)
        ExitLoop
    EndIf
Next

kor,

As "M" is of higher value in the ASCII table than "J", the highest element is "mikejones" at no #2 - so the returned value is quite correct. You have obviously misunderstood the function. ;)

For what you want I suggest something like this:

Local $aArray[5] = ["", "", "mikejones", "john", ""]

$iNon_Blank_Index = -1
For $i = 0 To UBound($aArray) - 1
    If $aArray[$i] <> "" Then
        $iNon_Blank_Index = $i
    EndIf
Next

ConsoleWrite("Last non blank element = " & $iNon_Blank_Index & @CRLF)

BTW: Function _ArrayMaxIndex only makes sense for numeric content.
