Remove elements from array with arraysearch

Recommended Posts

NizonRox

Hi, i'm currently facing problems with understanding how arrays work, or atleast a few commands that alter arrays.

My current situation is:

1. I'm taking the process list and putting it all in an array
2. I want to remove the boring common windows processes
3. Profit

And i'm currently stuck on step 2, while i already found this thread it dosn't seem that i can make it do what i want.

Current code:

Local $PList = ProcessList()
Local $RL[6] = ["smss.exe", "csrss.exe", "svchost.exe", "iexplore.exe", "chrome.exe", "conhost.exe"]
Sleep(1)
For $i=1 To Ubound($RL)-1
   Sleep(1)
   While Not @Error
   $iIndex = _ArraySearch($PList, $RL[$i], 1, 0, 0, 1)
   _ArrayDelete($PList, $iIndex)
   WEnd
Next

It seems to remove all but smss.exe from the array list unless i have it two times in the array.

 

Note: The sleep(1) is there to clear the error else the command wont fire for the rest of the array, any other way of doing it?

Also, you should do it this way instead.

For $i=Ubound($RL)-1 to 0 Step -1

Otherwise,  you'll find out you're deleting the wrong elements very quickly.


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.

Thanks, i found out that it's going to be a hassel to remove all the processes i don't want in my array. So i was thinking if there is there a way to remove everything in my array that dosn't match another array?

Try this:

Local $PList = ProcessList()
;~ _ArrayDisplay($PList)
Local $RL = ["smss", "csrss", "svchost", "iexplore.exe", "chrome", "conhost"]
Local $sTabooP = "(?i)((?:" & _ArrayToString($RL) & ")(?:\.exe)?\*?)"
Local $sProc
For $i = 1 To UBound($PList) - 2
    $sProc &= $PList[$i][0] & '*'       ; use * as séparator
Next
$sProc &= $PList[$i][0]     ; no final séparator

Local $sUserP = StringRegExpReplace($sProc, $sTabooP, "")
Local $aUserP = StringSplit($sUserP, '*', 2)
_ArrayDisplay($aUserP)

This looks kind of caotic, mind explaining what to expect from this?

You asked for a solution to your problem and I provided a fairly good one. Did you at least bother to run it?

The idea is to avoid O(n*m) array lookup and m*ArrayDelete. First a list of processes is grabbed, then we build a string of process names delimited by * which can't be found in process names. The list of processes you don't want to see is also converted into a string, each being separated by |which is suited for a regexp pattern. It even makes the .exe suffix optional in taboo list, as you would have noticed if you had taken a few seconds to look at the code.

We now use the power of a regular expression to remove any taboo name from the process list, convert what remains back to an array and display it.

So care to explain what is "caotic" there?

@jcHD You are already using _ArrayToString why not for plist as well?

#include <array.au3>
;Local $PList = ProcessList()
;Local $sProc
;~ _ArrayDisplay($PList)
Local $RL = ["smss", "csrss", "svchost", "iexplore.exe", "chrome", "conhost"]
Local $sTabooP = "(?i)((?:" & _ArrayToString($RL) & ")(?:\.exe)?\*?)"
Local $sProc = _ArrayToString(ProcessList(),"|",1, Default,"*",0,0)
#cs
For $i = 1 To UBound($PList) - 2
    $sProc &= $PList[$i][0] & '*'       ; use * as séparator
Next
$sProc &= $PList[$i][0]     ; no final séparator
#ce
Local $sUserP = StringRegExpReplace($sProc, $sTabooP, "")
Local $aUserP = StringSplit($sUserP, '*', 2)
_ArrayDisplay($aUserP)
#include <array.au3>
Local $RL = ["smss", "csrss", "svchost", "iexplore.exe", "chrome", "conhost"]
Local $sTabooP = "(?i)((?:" & _ArrayToString($RL) & ")(?:\.exe)?\*?)"
Local $sProc = _ArrayToString(ProcessList(),"|",1, Default,"*",0,0)
Local $sUserP = StringRegExpReplace($sProc, $sTabooP, "")
Local $aUserP = StringSplit($sUserP, '*', 2)
_ArrayDisplay($aUserP)

Because the process list is a 2D array, with process name and PID. I've examplified how to obtain the list on non-taboo process names only, but it's a trivial change to obtain both the names and their PID. I didn't have AutoIt handy to check which parameters to pass to _ArrayToString to obtain the same result.

      Associative Array Functions
      I've seen a couple of UDFs for this on the forum. One of them I quite like. But it's still nearly not as good as this method, IMHO.
      I don't recall if I discovered the "Scripting.Dictionary" COM object myself or if I got the original base code from somewhere online. I have recently searched the web (and here) hard for any AutoIt references to this, other than my own over the years I've been using this (in ffe, etc..), and I can find nothing, so I dunno. If anyone does, I'd love to give credit where it's due; this is some cute stuff! It could actually be all my own work! lol
      At any rate, it's too useful to not have posted somewhere at autoitscript.com, so I've put together a wee demo.
      For those who haven't heard of the COM "Scripting.Dictionary".. 
      If you've ever coded in Perl or PHP (and many other languages), you know how useful associative arrays are. Basically, rather than having to iterate through an array to discover it's values, with an associative array you simply pluck values out by their key "names".
      I've added a few functions over the years, tweaked and tuned, and this now represent pretty much everything you need to easily work with associative arrays in AutoIt. En-joy!
      The main selling point of this approach is its simplicity and weight. I mean, look at how much code it takes to work with associative arrays! The demo is bigger than all the functions put together! The other selling point is that we are using Windows' built-in COM object functions which are at least theoretically, fast and robust.
      I've used it many times without issues, anyhow, here goes..
      ; Associative arrays in AutoIt? Hells yeah! ; Initialize your array ... global $oMyError = ObjEvent("AutoIt.Error", "AAError") ; Initialize a COM error handler ; first example, simple. global $simple AAInit($simple) AAAdd($simple, "John", "Baptist") AAAdd($simple, "Mary", "Lady Of The Night") AAAdd($simple, "Trump", "Silly Man-Child") AAList($simple) debug("It is said that Trump is a " & AAGetItem($simple, "Trump") & ".", @ScriptLineNumber);debug debug("") ; slightly more interesting.. $ini_path = "AA_Test.ini" ; Put this prefs section in your ini file.. ; [test] ; foo=foo value ; foo2=foo2 value ; bar=bar value ; bar2=bar2 value global $associative_array AAInit($associative_array) ; We are going to convert this 2D array into a cute associative array where we ; can access the values by simply using their respective key names.. $test_array = IniReadSection($ini_path, "test") for $z = 1 to 2 ; do it twice, to show that the items are *really* there! for $i = 1 to $test_array[0][0] $key_name = $test_array[$i][0] debug("Adding '" & $key_name & "'..");debug ; key already exists in "$associative_array", use the pre-determined value.. if AAExists($associative_array, $key_name) then $this_value = AAGetItem($associative_array, $key_name) debug("key_name ALREADY EXISTS! : =>" & $key_name & "<=" , @ScriptLineNumber);debug else $this_value = $test_array[$i][1] ; store left=right value pair in AA if $this_value then AAAdd($associative_array, $key_name, $this_value) endif endif next next debug(@CRLF & "Array Count: =>" & AACount($associative_array) & "<=" , @ScriptLineNumber);debug AAList($associative_array) debug(@CRLF & "Removing 'foo'..");debug AARemove($associative_array, "foo") debug(@CRLF & "Array Count: =>" & AACount($associative_array) & "<=" , @ScriptLineNumber);debug AAList($associative_array) debug(@CRLF & "Removing 'bar'..");debug AARemove($associative_array, "bar") debug(@CRLF & "Array Count: =>" & AACount($associative_array) & "<=" , @ScriptLineNumber);debug AAList($associative_array) quit() func quit() AAWipe($associative_array) AAWipe($simple) endfunc ;; Begin AA Functions func AAInit(ByRef $dict_obj) $dict_obj = ObjCreate("Scripting.Dictionary") endfunc ; Adds a key and item pair to a Dictionary object.. func AAAdd(ByRef $dict_obj, $key, $val) $dict_obj.Add($key, $val) If @error Then return SetError(1, 1, -1) endfunc ; Removes a key and item pair from a Dictionary object.. func AARemove(ByRef $dict_obj, $key) $dict_obj.Remove($key) If @error Then return SetError(1, 1, -1) endfunc ; Returns true if a specified key exists in the associative array, false if not.. func AAExists(ByRef $dict_obj, $key) return $dict_obj.Exists($key) endfunc ; Returns a value for a specified key name in the associative array.. func AAGetItem(ByRef $dict_obj, $key) return $dict_obj.Item($key) endfunc ; Returns the total number of keys in the array.. func AACount(ByRef $dict_obj) return $dict_obj.Count endfunc ; List all the "Key" > "Item" pairs in the array.. func AAList(ByRef $dict_obj) debug("AAList: =>", @ScriptLineNumber);debug local $k = $dict_obj.Keys ; Get the keys ; local $a = $dict_obj.Items ; Get the items for $i = 0 to AACount($dict_obj) -1 ; Iterate the array debug($k[$i] & " ==> " & AAGetItem($dict_obj, $k[$i])) next endfunc ; Wipe the array, obviously. func AAWipe(ByRef $dict_obj) $dict_obj.RemoveAll() endfunc ; Oh oh! func AAError() Local $err = $oMyError.number If $err = 0 Then $err = -1 SetError($err) ; to check for after this function returns endfunc ;; End AA Functions. ; debug() (trimmed-down version) ; ; provides quick debug report in your console.. func debug($d_string, $ln=false) local $pre ; For Jump-to-Line in Notepad++ if $ln then $pre = "(" & $ln & ") " & @Tab ConsoleWrite($pre & $d_string & @CRLF) endfunc

      Hello,
      Is there a way wherein I can access the data from an array coming from an Excel file then have it assigned on to a variable?
      Below is a snippet of my current code. For now, it just reads and outputs the data from the excel file and have it displayed via an array.
      #include <Array.au3> #include <Excel.au3> #include <MsgBoxConstants.au3> Local $oExcel = _Excel_Open(False) If @error Then Exit MsgBox(0, "Error", "Error creating application object." & @CRLF & "Error: " & @error & " Extends: " & @extended) ; Open Excel Woorkbook and return object Local $sWorkbook = @ScriptDir & "\Excel Files\Test Data.xlsx" Local $oWorkbook = _Excel_BookOpen($oExcel, $sWorkbook, False, True) If @error Then MsgBox(0, "Error", "Error opening workbook'" & $sWorkbook & ".'" & @CRLF & "Error: " & @error & "Extends: " & @extended) _Excel_Close($oExcel) Exit EndIf Local $aResult = _Excel_RangeRead($oWorkbook) ; Error Trapping If @error Then MsgBox(0, "Error", "Error reading data from '" & $sWorkbook & ".'" & @CRLF & "Error: " & @error & " Extends: " & @extended) _Excel_Close($oExcel) Exit EndIf _ArrayDisplay($aResult) My Excel file has values from Column A to H with values from 1 to 30, what I desired to do is have the value in "A7" assigned on to a variable. 
       
      Any help is appreciated. Thanks in advance.

      i have a 3d array that is [10][20][6] for now lets assume that its [3][3][3] so it looks something like this 
      [[[1,2,3],[1,2,3],[1,2,3]], [[1,2,3],[1,2,3],[1,2,3]], [[1,2,3],[1,2,3],[1,2,3]]] i need to add another 1d  array to the position [2][3] ( i hope its clear) so it becomes like this 
      [[[1,2,3],[1,2,3],[1,2,3]], [[1,2,3],[1,2,3],[1,2,3]], [[1,2,3],[1,2,3],[1,2,3],[4,5,6]]] and i have no idea how

      To save myself a "search" nightmare, I'm trying to wrap my head around 3D arrays.
      Example: In "No Limit Hold'em", if I only play kings "KK" and queens "QQ"
      and I only play them from the positions of the "Button" or "Blinds"
      and do one thing if it's raised ahead or another if not raised.
      I know that this example would be simple as a 2D array but if I'm dealing with 77 possible hands in 9 possible positions and 6 possible conditions then I'm dealing with almost 700 data lines.
      Lastly, if I have a variables to represent the hand like $hand = "QQ"
      and $position = "Button" and $ahead = "Raised", could the 3D array simplify my search, or should I just stick to the 2D array ??
      Thank you in advance for any thoughts...
