Subscript used on non-accessible variable

Recommended Posts

Reizvoller

Greetings, 

Func pixelHunter ()
   Local $PixelHunt[2]

   Do
    $PixelHunt = PixelSearch (1, 1, 1016, 874, "0xCCE4CC", 0, 1, $sWorkOrderWin)
 Until $PixelHunt[0] > 0


EndFunc

So when I call up this function in my app it fires back "Subscript used on non-accessible variable"

Now, if I am understanding this message properly it is trying to tell me that the variable can't be seen by the function asking for it.

I replaced "Do...Until" with simply a "ConsoleWrite" the $PixelHunt value and it doesn't throw that error.

Any advice would be appreciated!

Pixelsearch returns an array.  $pixel hunt does not need to be declared as an array ahead of time remove the "[2]" from the declaration line.

 

Remove the do and until statement. 

It should look like this

 

$a=pixelsearch  (0,0,100,100, color)

If isarray  ($a)  then

;do whatever bc it was successful 

Else

;  do whatever not successful no color found

Endif

 

Your basically declaring an array 

$pixelhunt [0]

$pixelhunt [1]

$pixelhunt [2]

Then trying to assign a value to an unknown slot. 

If you went  $pixelhunt [0]=pixelsearch  (0,0,1,1,color) the return would  (should ,could?)

Be stored as $pixelhunt  [0][0]=x coord

$pixelhunt  [0][1]=y coord

I believe it would work this way.  It's been awhile.

      Hi Virtual People,
      My array works perfectly fine. However, what is the best practice if the line in the array doesn't have the correct amount of columns and if I can add a placeholder?

       
      For $count = 1 To _FileCountLines($FileRead1) Step 1 $string = FileReadLine($FileRead1, $count) $input = StringSplit($string, ",", 1) $value1 = $input[1] $value2 = $input[2] $value3 = $input[3] _Excel_RangeWrite($oWorkbook, $oWorkbook.Activesheet, $value2, "A1") _Excel_RangeWrite($oWorkbook, $oWorkbook.Activesheet, $value1, "B1") _Excel_RangeWrite($oWorkbook, $oWorkbook.Activesheet, $value3, "C1") Next

      hi all,
      reviewing the forum, this thread is applicable: 
       
       
      I wanted to know if there is now a better way to do this?
      In essence, I load a tab delimited txt file into an array (works well). I used tab, as some fields in the original csv contains commas.
      However, I needed autoit to manipulate this array, and output it as a csv.
      IF my array contains items with a comma, without double quotes around the field, then how best do I get a csv out of this?
      My current workaround is to filewritefromarray tab delimited, then open it in excel and save as a csv. I will need to check this to see how the address fields behave that contain a comma.
       
      Any thoughts would be appreciated.

      Hi All,

      I would like to know how you would take a FileLineRead and insert it into an array which then inserts it into Excel?
      One thing to know is the files content is broken up, so I only use half of the content within $FileRead1.
      So its imperative that the $value1, $value2, etc variables be used. 
      Code below:
      $FileRead1 = FileReadLine("C:\temp\sample.txt",1) For $count = 1 To _FileCountLines($FileRead1) Step 1 $string = FileReadLine($FileRead1, $count) $input = StringSplit($string, ",", 1) $value1 = $input[1] $value2 = $input[2] $value3 = $input[3] $value4 = $input[4] _Excel_RangeWrite($oWorkbook, $oWorkbook.Activesheet, $value1, "A1") _Excel_RangeWrite($oWorkbook, $oWorkbook.Activesheet, $value2, "B1") _Excel_RangeWrite($oWorkbook, $oWorkbook.Activesheet, $value3, "C1") _Excel_RangeWrite($oWorkbook, $oWorkbook.Activesheet, $value4, "D1") Next

      Hi Guys,
      Is it possible to get a variable on your For..Next loop? 
       
      Local $Lines1 = _FileCountLines(C:\temp\test.txt) Local $linesToCount2 = $Lines1 + 2 $var = Number($linesToCount2) For $count = 1 To _FileCountLines($FileRead2) Step 1 For $i = $var To $count Next ;Code does stuff here Next Somehow my code doesn't work even though I thought I could convert the variable to a Integer / Number.
      This code I posted above does not move to the next value.
      But the code below does... why is that?
      For $count = 1 To _FileCountLines($FileRead2) Step 1 For $i = 2 To $count Next ;Code does stuff here Next  
      Why is the For loop resetting itself?
      Is it because the program does not cache the variable and needs to keep on acquiring this variable each time?
      If so , how would you make this variable static?

      Hello,
      I'm trying to write a script that moves copies excel cells into an array. I'll than manipulate the values and send array into another program. 
      I don't want range to be specific to a workbook, or sheet, or set of cells.
      I want user to be able to highlight desired cells and to copy either normally ("Ctrl+C") or by a hotkey ("Alt+C"). 
      Could someone help me with this?
      Thank you,
      I've tried to write the framework: (edited)
      #include <MsgBoxConstants.au3> #include <Array.au3> #include <Excel.au3> HotKeySet("!v", "Pastedata") While True Sleep(1000) WEnd func Makearray() local $bArray ;User has cells already copied ;Convert clipboard into an array ;I don;t know how excel stores data to clipboard so don;t know how to bring it into array _Arraydisplay($bArray) MsgBox(0,0,$bArray) return $bArray endfunc func Pastedata() Local $aArray MsgBox(0,0,"wait",1) ;make array based on assumption user has already copied a range to clipboard $aArray = Makearray() ;paste code ;don;t worry about this I got the rest endfunc
