Problems with arrays

Recommended Posts

Wicked_Caty

In my current project I have a part that should convert from string to array, and later on that array should be converted to a string again.

The first part works just fine and I get the array just as I want it, but on the way back I'm encountering some issues...

Func Encode($data0)

    ; works just fine, just here for clarification.
    ; That if-statement in the middle is just there that I'm always getting a string with 5 symbols
    ; $data0 = "A" in this example

    Local $data1 = ""
    Local $tmp = ""
    Local $arr = StringSplit($data0, "", 2)

    For $i = 0 To UBound($arr)-1

        $tmp = AscW($arr[$i])

        If $tmp = 0 Then
            $tmp = "00000" & $tmp
        ElseIf $tmp > 0 And $tmp < 10 Then
            $tmp = "0000" & $tmp
        ElseIf $tmp >= 10 And $tmp < 100 Then
            $tmp = "000" & $tmp
        ElseIf $tmp >= 100 And $tmp < 1000 Then
            $tmp = "00" & $tmp
        ElseIf $tmp >= 1000 And $tmp < 10000 Then
            $tmp = "0" & $tmp
        ElseIf $tmp >= 10000 And $tmp <= 65535 Then
            $tmp = $tmp
        EndIf

        $data1 = $data1 & $tmp

    Next

    Return $data1

EndFunc
Func Decode($data0)

    ; does NOT work
    ; $data0 = "00065"
    ; via MsgBox and ConsoleWrite I could find out that it fails already before StringSplit
    ; when it fails, no message is given and everything just disappears

    Local $data1 = ""
    Local $tmp = ""
    Local $arr = StringSplit(String($data0), "", 2)

    For $i = 0 To UBound($arr)-1 Step 5

        $tmp = $arr[$i] & $arr[$i+1] & $arr[$i+2] & $arr[$i+3] & $arr[$i+4] & $arr[$i+5]
        $tmp = ChrW($tmp)
        $data1 = $data1 & $tmp

    Next

    Return $data1

EndFunc

Sorry for dropping all the #include, the GUI, the login screen, etc... It's not necessary for this problem and I needn't give you a 613kB file full of plain text for finding an error in 3 lines of code.

I found out that $arr is always empty, so there must be an issue with StringSplit. I suspected "00065" might be seen as an integer and converted it to a string, but that doesn't make it work. I already played around quite a while with that issue now, I hope some of you can finally relieve me.

Thanks

Could you provide example Input data? the one you make the first StringSplit?

Regards
Alien.

Is in the comments I added at the beginning of the files. In Encode() it's "A" and in Decode() it's "00065"

Sorry you already mention it.

So:

$data0 = "A" in this example

Then StringSplit() here in the first step is working because is only one character and you use a null delimiter:

Local $arr = StringSplit($data0, "", 2)

What is happening is in your second stage you have a bigger string with no Delimiters so the StringSplit() is not working properly.

Actually, using "ABC" in the first step is working too. 

Edit: Using delimiters, when there are none, is also a bit difficult :/

You are right sorry I just miss read it.

You could try to use IsInt() or IsString function to know if you are right and I think you are.

$data0 in the second function is a string indeed.

in your decode func is the line comcatenating string wrong, you try using 1 element to much  (0,1,2,3,4,5=6 elements)m correct it to: 

For $i = 0 To UBound($arr)-1 Step 5

        $tmp = $arr[$i] & $arr[$i+1] & $arr[$i+2] & $arr[$i+3] & $arr[$i+4]
        $tmp = ChrW($tmp)
        $data1 = $data1 & $tmp

    Next

Thanks. I really didn't expect the problem there. I'm coding for almost 2 years now in several languages, but I still get confused by starting to count at zero xD

If you're saying  $data0 fails before the string split(),  which is right at the beginning of decode (). I'd have to assume there is a problem with the variable in another part of the program. 

Or I could be completely misinterpreting what you mean by "fails"

You could use some integrated String* funcs

$data0 = "ABC"

$test1 = Encode($data0)
Msgbox(0,"encode", $test1) 

$test2 =  Decode($test1)
Msgbox(0,"decode", $test2)


Func Encode($data)
    Local $data1 = ""
    Local $arr = StringSplit($data, "", 2)
    For $i = 0 To UBound($arr)-1
        $data1 &= StringFormat("%05s", AscW($arr[$i]))
    Next
    Return $data1
EndFunc

Func Decode($data)
    Local $data1 = ""
    Local $arr = StringRegExp($data, '.{5}', 3)
    For $i = 0 To UBound($arr)-1
        $data1 &= ChrW($arr[$i])
    Next
    Return $data1
EndFunc

 

Edit
For the fun only

$data0 = "ABC"

$test1 = Encode($data0)
Msgbox(0,"encode", $test1) 

$test2 =  Decode($test1)
Msgbox(0,"decode", $test2)


Func Encode($data)
   Return Execute('"' & StringRegExpReplace($data, '.', '" & StringFormat("%05s", AscW("$0")) & "') & '"')
EndFunc

Func Decode($data)
   Return Execute('"' & StringRegExpReplace($data, '.{5}', '" & ChrW("$0") & "') & '"')
EndFunc

      Hello AutoIt community
      I run into speed problem in my script wich i cant solve myself, problem is with decoding texture loop - for better explanation, you need extract from file pallete (16x 16 RGB color) and picture data (224 * 128 byte), then use correct color for your picture data.... nothing extra hard and also texture is quite small 224*256
      it is for my car model viewer/later maybe editor GranTurismo 2 from Playstation 1, so its old dataformat and i cant understand why AutoIt take so long to decode texture when good old Playstation almost 2,5 decades old can do that nearly immediately (when you list through cars in shop or garage)
      My first atempt was create all trought dllstructure, because its easier approach, but it was soooo slow (40-50s for create textures) then i upgrade my routine via arrays, first 3D arrays later only 1D, next i put decoding colors outside loop but it is still not enough, my last version took cca 15s wich is still unacceptable for car model viewer when you click on one carmodel from listview (1100 cars for whole game) and you must wait 15-16s for model to load....  oh and i forgot mention some cars have more then 1 color (much more... 8-9-10 etc) soloading take 8-9-10 times more time
      in attachment i post texture file from GranTurismo 2 for one car (contain only 1 color) and also my dll struct version and array version code

      Hello,
      Does somebody knows a quick way to split eash word to an array in a text?
      I've a text and want to have each word in that text in an array.

      I tried to get in some way multiple seperators inside stringsplit but couldn't get it to work.
      I hope to get an array like :
      $aArray[0] = "PARIJS"
      $aArray[1] = "AFN"
      $aArray[2] = "Air"
      ....
      sample text: PARIJS (AFN) - Air France-KLM heeft de financieel directeur van het Franse nuts- en vervoersbedrijf Veolia, Philipe Capron, in het vizier om de nieuwe topman van de luchtvaartcombinatie te worden. Volgens de krant La Tribune wordt Capron als favoriet beschouwd om de topfunctie te gaan vervullen. AdChoices Advertentie Volgens bronnen tegen La Tribune is de keuze voor Capron zelfs al gemaakt door Air France-KLM en zal zijn voordracht volgende week worden voorgelegd aan de raad van toezicht bij het bedrijf. Capron zou dan de opvolger worden van de opgestapte topman Jean-Marc Janaillac. In mei trad Janaillac af nadat het hem niet was gelukt buiten de bonden om zaken te doen met het eigen personeel. Sindsdien heeft een interim-bestuur de dagelijkse leiding. De zestigjarige Capron is sinds 2014 financieel directeur bij Veolia. Daarvoor werkte hij onder meer bij mediaconcern Vivendi. Minder macht Overigens zijn er ook geruchten dat de nieuwe topman van Air France-KLM direct een zetel zou krijgen in de raad van commissarissen van KLM. Binnen de Nederlandse divisie, die juist alles op alles zet om minder macht naar Parijs te laten vloeien, is men volgens ingewijden verbolgen over die gang van zaken. ,,Stank voor dank", zo klinkt het in de wandelgangen. Eerder zou Janaillac ook al hebben geprobeerd om een dikkere vinger in de pap te krijgen bij KLM, dat door de bank genomen beter presteert dan haar Franse zustermaatschappij. Dit lukte eerder niet, onder meer door inmenging van het Nederlandse kabinet. AdChoices Advertentie Geruchten Een woordvoerder van Air France-KLM wilde niet reageren op de geruchtenstroom. Het concern gaat er vanuit dat binnen afzienbare tijd een nieuwe bestuursvoorzitter benoemd zal worden. Minister Cora van Nieuwenhuizen (Infrastructuur) wilde evenmin ingaan op geruchten. ,,Ik heb hierover nog geen contact gehad met KLM, dus dat wil ik eerst even afwachten'', zei ze. Tweede Kamerleden spraken deze week tijdens een debat nog maar eens hun zorg uit over de ontwikkelingen bij Air France-KLM. Zij drongen aan op herbevestiging van oude afspraken over de relatief zelfstandige positie van KLM binnen de groep.>Exit code: 0 Time: 28.52

      Hello Members of this best Forum
      i have a question please
      for example if i have a long string
      and i want to extract a text between two tag
      what i can do to make that?
      note :
      i know that there is a
      StringRegExp function
      it's do that work
      but it result is be as an array
      i want the result to be a string
      is there any function on autoit can do that?
      Thanks in advance.

      Hello!
       
      I wrote myself a script to follow Google Maps Polyline encoding steps: https://developers.google.com/maps/documentation/utilities/polylinealgorithm, and that works (although I think that it's a bit janky), but now I'm having issues getting the output.
       
      When I run the script, all the points come out correctly in the console, and even when they're the only things that I log, it displays them fine. However, I'm adding each point into a variable to return all of them at once at the end, fully formatted, and it's only taking the very first point. I can't figure out what I'm doing wrong, as it seems fine.
       
      When run with the default value, it should output this at the end: Custom Polygon: _p~iF~ps|U_ulLnnqC_mqNvxq`@
      But instead I'm just getting this: Custom Polygon: _p~iF
       
      I know that it's reaching the string combination lines because it's logging the data before it (and even if a put log AFTER the $sPolygon &= $aPoints[0], it's logged fine).
       
      Here's my full code (problem is lines ~209 - 234, search "$sPolygon &= $aPoints[1]"):

      I've tried:
      $sPolygon &= $aPoints[0] & $aPoints[1] ;---- $sPolygon = $sPolygon & $aPoints[0] & $aPoints[1] ;---- $sPolygon = $sPolygon & String($aPoints[0] & $aPoints[1]) ;---- $sPolygon = String($sPolygon) & String($aPoints[0]) & String($aPoints[1]) ;---- $sPolygon &= $aPoints[1] $sPolygon &= $aPoints[0] ;----  
      I'm sure it's something basic that I'm overlooking, but I don't understand why it's not combining the strings. 
      Also, unrelated, why doesn't $LogFile = FileOpen($File, 9) create the directory/ file if they don't exist? 9 should be $FO_CREATEPATH (8) + $FO_APPEND (1)?
      Thanks!

      Hi,
      I'm looking for a way to take a number value from a Row2 of a 2D array and according to this check if files that appear in rows 3-11 in the array exists.
      For example, if the number in Row2 is 5 I need to check for the files in Row 3-6 only, if it is 6 than rows 3-7 and so on.
      I thought on using a FOR loop but I have very little experience with those.
      Can you suggest the best way to do what I need?
      BTW, the files in Rows 3-11 will usually have blank value for any row above the number in Row2 (e.g. Row2 = 5 so Rows3-6 will have values but 8-11 be empty), The values I need are in Column 1 of the array, the name of the key from the INI file that the array was created from is in Column 0.
      Full Example:
      Row2 of Array:
      Col0 = Games# - Col1 = 5
      Rows3-6
      Col0 = Exe2 - Col1 = Path To File
      Col0 = Exe3 - Col1 = Path To File
      Col0 = Exe4 - Col1 = Path To File
      Col0 = Exe5 - Col1 = Path To File
      I need that if Row2 is 5 to check these above for rows if the file exists, if it was 6 then the next row as well and so on up until number 10 in Row2 as it can't go above 10.
      So basically for whatever number in Row2 from 2-10 need to check 1-9 rows from 3-11 to see if the files in Col1 exists and if any of them don't exist it should call a function that shows an error message.
      I'm pretty sure I have the first line of the for look correct:
      For $i = 1 To $aAIO[2][1] Just not sure how to continue from there, also not sure if $i should be equal 1 or 2.
      Help will be appreciated.
