empty element / 0 number in array

Recommended Posts

Once again the problem of mixing datatypes in comparisons pops up - I am not going to explain it again, so please search for a previous thread where I have done so. ;)

Basically, if you want to compare the values in the array to a string ("") then use String to convert them to the same datatype:

If String($tableau[$i]) = "" Then
or use the == operator so that AutoIt does it for you. :)

The problem was that I was saving index elements of a listview and when the 0 index element was in the array, my test of empty element was wrong with 0.

I didn't know 0 number and empty element was considered as same value.

Thank you very much for the fast answer.

I'm comparing with 0 and got this result:

Local $tableau[5] = ["",0,"","test",8]

For $i = 0 to 4
    If $tableau[$i] = 0 Then
        ConsoleWrite($tableau[$i] & " : empty element" & @CRLF)

Console OutPut

 : empty element
0 : empty element
 : empty element
test : empty element
