#include <Array.au3>


;;automation to run functions from files
$maxFun = 35


Global $v[1]

For $l = 1 To $maxFun Step 1
_ArrayAdd ($v[$maxFun] = FileReadLine("C:\IanLogTest\functionLog.log", $l))
Next
MsgBox("", "count", $v[$maxFun])

so that is my whole script... what i want it to do is have $maxFun be a text document and the maximum number of lines in the text doc is 35 at any given time.. and then add each line as an element to my array ($v[]). i just dont know how to create a blank array without using 35 ["",""...] as "blank" elements... is there an easy way to do this with a FOR loop? i feel that there is..

or should i just write out 35 variables and then $var1 = fileReadLine...... over and over.?

Thanks

LetsAuto,

Look at FileReadToArray in the Help file = it puts each line of a file into an array element for you. ;)

And also look at ReDim to see how to resize an array if you ever need to. :)

If you just declare the array as "Global $v[36]" the array will be empty already. BTW, you need to declare it to 36 because you're starting the For loop at 1 and running it 35 times. Here's one way of doing it.

#include <Array.au3>
;;automation to run functions from files
Global $maxFun = 35
Global $v[36]
Global $hFile = FileOpen("C:IanLogTestfunctionLog.log") ; use a handle when using FileReadLine, it's much faster
For $l = 1 To $maxFun ; The step isn't needed if you're only incrementing by one every time.
    $v[$l] = FileReadLine($hFile)
Next
MsgBox("", "count", $v[$maxFun])
FileClose($hFile)

Or do it this way without the loop.

#include <File.au3>
;;automation to run functions from files
Global $v[1]
_FileReadToArray("C:IanLogTestfunctionLog.log", $v)
MsgBox("", "count", $v[$maxFun])

Awesome, thanks a lot! i had not found FileReadToArray because i just used FileReadLine without looking through the help files. ill post again if i run into issues :)

LetsAuto,

without looking through the help files

Always a good idea to look there. ;)

@Melba23, agreed i will make sure to scan through that next time.

@BrewManNH, if i want that message box to display all 35 lines, could i do something like....

MsgBox("", "count", $v[1] To $v[$maxFun])

??

You can't do it that way. You'd have to create a string to display it. Look at _ArrayToString, and use @CRLF as the Delimiter parameter.

LetsAuto,

You will have to put all the elements into a single variable: :)

$sCount = ""
For $i = 1 To $v[0]
    $sCount &= $v[$i] & @CRLF
Next
MsgBox(0, "Count", $sCount)

or use another of those functions hidden away in the Help file: ;)

MsgBox(0, "Count", _ArrayToString($v, @CRLF))

      Haven't had much time to code recently. However the following thread inspired me.
      The debate about linear, parallel and binary search methods was rather interesting and, in an attempt to be diplomatic, I decided to combine @jchd's suggestion with @LarsJ's binary search example. I decided that the binary search algorithm required modification to make it more linear. As usual, 'if you invent something, it probably already exists and if it already exists, it exists for a reason'. My first attempt was not all that good. The code worked but was really a mess. I blame peer pressure (to post an example of a parallel search method).  I will delete that old code in due course.
      With a little memory jogging and a glance at the help file, the solution turned out to be quite easy: I just needed a better understanding of Euler. Further modification will be needed to work with more complicated unicode strings. The output could be returned as an array or a delimitered string. I'm not so interested in those details. I'm just going to post the algorithm for now and anyone, who wants to, can modify it to suit their needs. Both arrays must contain at least 1 element.
      Local $aFoo = [0,1,2,3,4,5,6,7,9,10,11,12,13,14,15,16,19,20,23,24,26,30,35,39,40,41] Local $aBar = [0,1,5,6,7,8,9,10,11,12,13,14,17,18,19,21,24,25,26,27,34,35,38,40] ParallelExponetialSearch($aFoo, $aBar) ; Compares two lists - returning positive matches. Each input array must be unique (individually) and in alphabetical order. Func ParallelExponetialSearch($aFoo, $aBar) Local $sFind, _ $iMin_F = -1, $iMax_F = UBound($aFoo) -1, $Lo_F = $iMin_F, $Hi_F, _ $iMin_B = -1, $iMax_B = UBound($aBar) -1, $Lo_B = $iMin_B, $Hi_B While $iMin_F < $iMax_F And $iMin_B < $iMax_B ; Toggle Arrays - Which array has most untested elements? This is the one we want to search next, ; so we can bypass more comparisons because (in theory) mismatches have a greater chance of being skipped. If $iMax_F - $iMin_F >= $iMax_B - $iMin_B Then ; $aFoo has more (or an equal number of) untested elements $Hi_F = $iMax_F $iMin_B += 1 $sFind = $aBar[$iMin_B] While $Lo_F < $Hi_F ; search $aFoo For $i = 0 To Floor(Log($Hi_F - $Lo_F) / Log(2)) $Lo_F = $iMin_F + 2^$i If $aFoo[$Lo_F] = $sFind Then $iMin_F = $Lo_F ; each match should be added to the output [perhaps an array] ConsoleWrite($sFind & " found at $aFoo[" & $Lo_F & "] = $aBar[" & $iMin_B & "]" & @LF) ExitLoop 2 ElseIf $aFoo[$Lo_F] > $sFind Then $Hi_F = $Lo_F -1 $iMin_F += Floor(2^($i -1)) $Lo_F = $iMin_F ContinueLoop 2 EndIf Next $iMin_F = $Lo_F ; minimum increment is one WEnd Else ; $aBar has more untested elements $Hi_B = $iMax_B $iMin_F += 1 $sFind = $aFoo[$iMin_F] While $Lo_B < $Hi_B ; search $aBar For $i = 0 To Floor(Log($Hi_B - $Lo_B) / Log(2)) $Lo_B = $iMin_B + 2^$i If $aBar[$Lo_B] = $sFind Then $iMin_B = $Lo_B ; each match should be added to the output [perhaps an array] ConsoleWrite($sFind & " found at $aFoo[" & $iMin_F & "] = $aBar[" & $Lo_B & "]" & @LF) ExitLoop 2 ElseIf $aBar[$Lo_B] > $sFind Then $Hi_B = $Lo_B -1 $iMin_B += Floor(2^($i -1)) $Lo_B = $iMin_B ContinueLoop 2 EndIf Next $iMin_B = $Lo_B ; minimum increment is one WEnd EndIf WEnd EndFunc ;==> ParallelExponetialSearch I hope this will be useful to someone. I believe it deserved a thread of its own!

      Afternoon!
      I have a requirement to return both a string and an array from a function so as a result I put them both into an array and returned that.  I can access them in their entirety after returning them but then I can't seem to access the array elements after this.  Should I be able to or is there a prettier way?
      #include <Array.au3> ;Memory info returned as a string and an array $memoryInfo = _getMemoryInfo() msgbox(0,"Memory Info",$memoryInfo[0]) _ArrayDisplay($memoryInfo[1],"Memory as an Array") Local $newArray[7] $memoryInfo[1] = $newArray msgbox(0,"Test element",$newArray[0]) _ArrayDisplay($newArray) Func _getMemoryInfo() Local $newArray[7] Local $array = MemGetStats() $newArray[0] = $array[0] ;% of memory in use $newArray[1] = Round($array[1]/1024 * 0.001,2) ;Total physical RAM $newArray[2] = Round($array[2]/1024 * 0.001,2) ;Availaible physical RAM $newArray[3] = Round($array[3]/1024 * 0.001,2) ;Total pagefile $newArray[4] = Round($array[4]/1024 * 0.001,2) ;Available pagefile $newArray[5] = Round($array[5]/1024 * 0.001,2) ;Total virtual $newArray[6] = Round($array[6]/1024 * 0.001,2) ;Available virtual $memoryUsage = $newArray[1] - $newarray[2] $pagefileUsage = $newArray[3] - $newarray[4] ;Output/Return Local $returnArray[2] $returnArray[0] = "Memory: " & $memoryUsage & " GB/" & $newArray[1] & " GB " & @CRLF & "Pagefile: " & $pagefileUsage & " GB/" & $newArray[3] & " GB " $returnArray[1] = $newArray return $returnArray EndFunc A bit messy but hopefully it's understandable what I'm trying to achieve.
      Thanks!

      I am having difficulties getting updated results from GUICtrlCreateInput. I wrote a small script to demonstrate what I am trying to do.
      This script reads a text file into an array and displays the Name and Number from the text file.
      The user can check a name and change the number, and the results are displayed in _ArrayDisplay.
      Only the Checked names are displayed in their original position. This is necessary for future
      plumbing.
      The problem with this script is the original number is returned, not the changed number. I cannot
      figure out how to get the updated number to be displayed.

      I am working on a Video Player Test Script. I am reading a text file into a 3d array to be displayed in a GUI.
      Array Content:
      [x][0]FileName.mp4
      [x][1]UsageCount -> Up to a 4 digit number
      [x][2]EnableUsageCount (True/False)
      In the GUI the user can check the filename box, edit the number of usages and check EnableUsageCount to turn on the UsageCount control using the UsageCount number for the maximum number of plays.
      To make this easier to deal with I have removed the EnableUsageCount section, and am just concentrating on getting a method to put the edited (or unchanged) UsageCount in the array. Currently nothing is read into the array, due to my using the wrong method in the Case statement.
      Here are code snippets of what I am trying to do:
      ; Snippets from script ; I read the text file at the bottom and put the .mp4 filenames in $aManifest[x][0] and UsageCount in $aManifest[x][1] ; Then I create a GUI to display the .mp4 filenames with checkboxes and the UsageCount to the right. UsageCount is editable by the user. ; If the filename is checked, I want to read the filename into $aCheckedVideos[x][0] and the updated UsageCount in $aCheckedVideos[x][1] ; The GUICtrlRead($aVideoName[$i]) with Case $GUI_CHECKED & UNCHECKED works for the checkboxes ; This section puts the filenames in the GUI with a checkbox For $i = 0 to $iMMCount Step 1 $sMP4Text = $aManifest[$i][0] $iMP4Length = StringLen($sMP4Text) $aVideoName[$i] = GUICtrlCreateCheckbox($sMP4Text,$iLeft, $iTop) $iTop += 30 Next ; This section reads numbers from the Manifest array, and I want to be able to change the number and have them saved. ; So the Case $GUI_CHECKED & UNCHECKED won't work here, and I can't figure out what I should be doing here. For $i = 0 to $iMMCount Step 1 $sUsageText = $aManifest[$i][1] $aUsageCount[$i] = GUICtrlCreateInput($sUsageText,$iLeft, $iTop, 50,18, $GUI_DOCKAUTO) GUICtrlSetPos($aUsageCount[$i],200) $iTop += 30 Next While 1 $nMsg = GUIGetMsg() Switch $nMsg Case $GUI_EVENT_CLOSE Exit Case $idCloseGUI For $i = 0 To $iMMNewCount Step 1 Switch GUICtrlRead($aVideoName[$i]) Case $GUI_CHECKED $aCheckedVideos[$i][0] = $aManifest[$i][0] ; If checked, I put the results into a two D array Case $GUI_UNCHECKED ; where Video Name is $aCheckedVideos[x][0] EndSwitch Switch GUICtrlRead($aUsageCounter[$i]) Case $GUI_CHECKED $aCheckedVideos[$i][1] = $aUsageCount[$i] ;I want to put the text (numbers) in $aCheckedVideos[x][1] Case $GUI_UNCHECKED ;but what is returned is blank, probably due to EndSwitch ; $GUI_CHECKED being the wrong thing.

      is wrong, and this is what I am looking for help with. Instead of $GUI_CHECKED what should I be looking for?
      The worst part of this is I had this working late last night, and then lost my changes and cannot for the life of me remember how I had this working.
      Help is truly appreciated!

      Hello,
      I have used this forum to get help many times. I thought it was time to (hopefully) help others.
      I created a script that reads a text file with a list of videos, displays the videos in a GUI with checkboxes next to the names, and displays the selected videos. This will become a part of a larger script I am creating to test a video player. The tough part for me was creating the GUI and Dynamic list of videos. I had a lot of trouble finding samples to help me, but finally found one  written by Melba23. The link is in the code, so he gets credit for helping! I also have not used arrays much and they are very picky about looping through the arrays without getting the dreaded error " Array variable has incorrect number of subscripts or subscript dimension range exceeded."  However diligence paid off!
      To run this code, take the video names commented below and create a videos.txt file in your script execution directory. You can put however many video names in this list. Thus the dynamic features of the code.
