_StringBetween - Array error

[Olsson]

Hey guys!

While executing this command:

$b_html = _IEBodyReadHTML ($oIE)
$b_b = _StringBetween ($b_html, "document.snd.t"&$b_unit&".value=", ";")
$t_built = $t_built + $b_b[0]

I get this error:

dra2.au3 (138) : ==> Subscript used with non-Array variable.:
$t_built = $t_built + $b_b[0]
$t_built = $t_built + $b_b^ ERROR

I know "why" this is happening - This is reading from a website and inserting this info into another function. But $b_b is only a valid array when the _StringBetween is functional. So if the website takes to long to load, or it loads wrong, my program crashes. Is there any possible way to make it.. Not crash when this fails?

Thanks,

Olsson

You can test to see $b_html contains the start and end string first, and you can test @error after calling _StringBetween before using $b_b as an array, or check that $b_b is an array.

How do I test if it is an array? Then it should be able to just - If $b_b is an array, then execute, if it's not an array, then do nothing?

Hey,

here are some options

$b_html = _IEBodyReadHTML ($oIE)
$b_b = _StringBetween ($b_html, "document.snd.t"&$b_unit&".value=", ";")
If @error Then Exit 1; Return SetError(1, 0, 0) ; option 1
;~ If Not IsArray($b_B) Then Return SetError(1, 0, 0) ; Exit 1 ; option 2
;~ If Not @error Then $t_built = $t_built + $b_b[0] ; option 3
;~ If IsArray($b_B) Then $t_built = $t_built + $b_b[0] ; option 4

Thanks, seems to work! Trying it out right now!
