Working with 2d arrays

Recommended Posts

Im trying to iterate through a 2d array created by 

ProcessList()

function that returns a 2d array containing names and pid's, i wanted to filter through the names and delete entries that have "svchost.exe" and this is how i did it

Func _Sanitize($array)
    For $x = 1 To UBound($array) - 1
          ConsoleWrite($array[$x][0] & @CRLF)
        If $array[$x][0] == "svchost.exe" Then
            _ArrayDelete($array, $x)
        EndIf
    Next
EndFunc   ;==>_Sanitize

And i get this error message

Quote

Array variable has incorrect number of subscripts or subscript dimension range exceeded.:
If $array[$x][0] == "svchost.exe" Then

If ^ ERROR

What is wrong?

If you're going to delete elements of an array in a loop, you have to run the loop in reverse. Instead of

For $x = 1 To UBound($array) - 1

Use this

For $x = UBound($array) - 1  To 1 Step - 1

Oh it makes sense, i get it now because i am deleting entries my array is getting smaller and the for loop will fail because it wont have those entries at the bottom anymore. Thanks for the help.

      back when I was still doing autohotkey you could write (in code) spanisha::á
      and whenever you were in google docs or notepad you could type (in the document) spanisha  and it instantly turns it into á 
      I tried doing this in autoit, here's what I have so far (my entire code so if this language requires a main function or a return/exit to function properly please let me know):
      ;is this a proper comment? HotKeySet ( "spanisha" , "SendAltered" ) Func SendAltered() Send("á", flag = 0); EndFunc I assume that autoit follows a sort of contemporary hotkey pressing model where you have to hold all keys at the same time? which makes this impossible. So
      I'm wondering if anyone has a workaround for this? or maybe an alternative to HotKeySet()
      I have a vague memory of someone saying that doing something like spanisha:á would work. I don't know if I'm slightly off syntax but this doesn't work.
      Also I tried doing 
      ;is this a proper comment? ;HotKeySet ( "a" , "SendAltered" ) ;spanisha::á Func SendAltered() Send("á"); EndFunc just to try and debug,
      I'm also wondering if my approach is fundamentally wrong since HotKeySet() was made for something like !^A. Or if Send() is syntactically wrong.
      I'm also noticing on these forums that specifying installation is important so to whom it may concern I downloaded both installers, editor and main files. Although I'm about to be real mad if the editor installation makes a difference.

      I have to press tab to reach a selected button then double click on that
      Here's my script but its not working:
      WinActivate("Policy Decisions -- Webpage Dialog","")
      Sleep(3000)
      Send("{TAB}")
      Send("{TAB}")
      Send("{TAB}")                    // at this point its working according to my need  but double click is not working
      Mouseclick("Left",510, 320, 2, 0)

      Hi, 
      I have a string like this : 
      Global $Msga = "urrent directory is /send.  (Submission of file with log number 29381077284 is confirmed)";
      I want to extract the number 29381077284  from the string. I did StringSplit to split based on "(" and then use space to reach there, But it's not a good choice. 
      Can anyone help me with regular expression to find the number from String using AutoIT. TIA
