If a row doesn't exist in Array

Go to solution Solved by dar100111,

Hey All,

I want to do a certain set of conditions base of if there is no row 1 in an array.  When I pull the array from the website and there is no information there is only the column headers in row 0. 

I was thinking of having a variable pull out of an array example:   $invarray[1][1] 

If it fails do one thing and if it's successful do another.

Is this the best way to do this?  I haven't messed with the @error macro but have seen it built into input boxes frequently.

Thank you in advance.

"If UBound($invarray) > 1 Then" will check the array to make sure it has more than 1 row.

If I posted any code, assume that code was written using the latest release version unless stated otherwise. Also, if it doesn't work on XP I can't help with that because I don't have access to XP, and I'm not going to.

I hereby grant any person the right to use any code I post, that I am the original author of, on the autoitscript.com forums, unless I've specifically stated otherwise in the code or the thread post. If you do use my code all I ask, as a courtesy, is to make note of where you got it from.

Can you please post some code that shows what you are trying to do. My best guess is something like this:

If IsArray($inarray) Then
    If $inarray[1][1] = "" Then
        ;Nothing found
        ;Data found


IsArray tests whether or not the variant is an array type but it isn't good enough to allow you to access [1][1] directly in all cases.

For instance, DOM objects may return empty arrays and the latest beta introduces them as native AutoIt constructs.

Safe access to index [1][1] can only be asserted by

If UBound($aVar, 0) = 2 AND UBound($aVar, 1) > 1 AND UBound($aVar, 2) > 1 Then
    ; OK play with $aVar[1][1]
    ; something got wrong
