How to find number of elements present in an array?

I have assigned the output of _ExcelReadSheetToArray($mappingexcel,1,1,0,0,1) to $mappingexcelarray

$mappingexcelarray =_ExcelReadSheetToArray($mappingexcel,1,1,0,0,1)

Now, I want to know how many elements are present in this array?

Can you please help?

regards,

Krishna

krishpun,

From the Help file for _ExcelReadSheetToArray:

"Returned array has row count in [0][0] and column count in [0][1]"

So a bit of simple arithmetic will give you the number of spaces in the array that are available for data. :)

If you want to know how many of those spaces actually hold data, then you will need to set up 2 nested loops and check each element in turn - along these lines: :)

; Zero the count
$iCount = 0
; For each row
For $iRow = 1 To $aArray[0][0]
    ; And for each column in the row
    For $iCol = 1 To $aArray[0][1]
        ; Increase the count if the element is not empty
        If $aArray[$iRow][$iCol] <> "" Then $iCount += 1
    Next
Next
; $iCount now holds the number of elements in the array which hold data
