Array Compare & Add

[Donovan6]

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.

please note i have the whole thing already coded, i just need the part that can basically loop search an arrays entries and if variatios to it are found, add them and includ ethem in the array and use the new, updated array to search for more. 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. ;-)
