Array Compare?

[Hassaan]

Hi, I want to compare two arrays and store the uncommon elements in another array. I searched through the help file but cant find any function to achieve that. Can someone help me out?

PS: Srry if the question is noobish, i started yesterday

Hi, Welcome to forum.

for comparing Arrays you can use _ArrayCompare() and uncommon elements can be stored using _ArrayAdd()

array elements are strings or the values? Maybe i can write something for you...

Hi sorry for the late reply, array elements are strings. Would be great if you can direct me with a code. Ill check out the links too.

Seems strange but _ArrayCompare() is not in the help file :/ ill check it out online. Thanks!

_ArrayCompare() is a User Defined Function which is not yet added to standard AutoIt Functions (in/ex).

And can you provide an example of what you exactly want, and in which order?

its like im getting text from a chat room, what i need to do is read the last line which was written. I have managed to get the text and store it in an array. Now what im thinking is that ill do the same procedure after a second and then by comparing both arrays ill get a new array which will have the lines which were not read previously.

So you have two arrays. The newer array has lines added at the end?

If this is true get the number of records of array A ($iItemsA) and start reading in Array B on line ($iItemsA+1).

Usually arrays have the number of records in element 0. If this is not true then you get the number of records by using function UBound().

hah didnt think of that, thanks man.

And before you do the next compare you have to copy array B to A.

This is in Autoit:

$arrayA = $arrayB
