Array Compare & Add

6 posts in this topic

Hey Folks,

Got a little logic problem. I want to use an array that contains predefined values. It must be used as a filter basically to detect things that are not the same as items in it.

Basically its detecting drive letters in the registry entries to system/data/private folders.

So in logic, it should contain one entry say Drive letter C.

Local $Array[1]

$array = 'C'

and then it must search Values which will be something like...

$Value1 = Regread(blah blah get the data in registry)

then.... this is the part i cant really get my head around.

If it finds something thats different from "C", it must add that item to the array and use it as a filter to detect (if there are) even more drive letters different now to the new Array entries.

So if it finds 3 'C' entries and one "D" it must add the D and continue searching till it gets an "E" or something else.

I cant seem to code it, don't know what can basically loop an arrays entries and compare them to external data and add the data if a variation is found.

If someone can just outline it for me, i can do the rest.

My attempts with do... until fail and i just deleted them.

Donovan6,

Look at _ArraySearch and _ArrayAdd in the Help file. Sample code:

If _ArraySearch($aList, $PossibleNewDriveLetter) = -1 Then _ArrayAdd($aList, $PossibleNewDriveLetter)

This seems to work, but I would caution against manipulating the array that you are searching all in one loop. In C# I would recommend a hashmap, but there is no support for this in AutoIt. The above _ArrayAdd may in fact be the best solution.

neema,

I am delighted that my proposed solution, and AutoIt's Array UDF, meet with your approval. ;-)
