How do I start a loop through an array at different points? [solved]

4 posts in this topic

#1 ·  Posted (edited)

Dear AutoIt Community,

I'm not having any luck figuring out a way that will let me start a loop through an array at different points in the array.

Say I have an array called $av_Array and at this particular time I need the loop to start at $av_Array[159] and continue until it gets to UBound($av_Array). Next time I run the program I might need it to start at $av_Array[5689] and continue until it gets to UBound($av_Array)... how would I go about this?

Compounding my problem is that I have 3 sets of nested loops, the top two of which I'll need to set the loop entry point for.

Any and all help is greatly appreciated.

Kind regards,

I don't know if it helps, but you can try:

Func _LoopArray($aArray, $iStart=0, $iEnd="")
If $iEnd="" Then $iEnd=UBound($aArray)-1
For $i=$iStart To $iEnd
;Do something

@taietel: Thank you very much for your help! Your idea works perfectly... I've only changed the EndIf to EndFunc ;-)

Func _LoopArray($aArray, $iStart=0, $iEnd="")
If $iEnd="" Then $iEnd=UBound($aArray)-1
For $i=$iStart To $iEnd
  ;Do something
EndFunc ;==> _LoopArray

      at first: i'm new here, so please forgive me my mistakes, and show them to me, just that i can learn to do better in the future.
      Now to my Problem: i have an excel sheet, where i just need some columns for further actions, but i have no idea how to add single columns to a new array.
      I found the following code(the one i just added as a file) from 'water' in this forum, but i wont get how i could add multiple columns into a new array.
      The biggest problem in my situation is that i dont know the count of the rows i need for the array, i just got a fix number of rows, which is 4.
      Hope you can help me, and sry again for this 'unlucky illustration'.
      btw: how can i add code shown as code here, instead of posting it as a attached file?.

      Ahoy Autoit Community!
      After many trials and errors I am unable to solve a problem I am facing and would appreciate any kind of input or better yet a solution 
      The Premise: An embeded slideshow viewer that runs after double-clicking an item in a ListView (each item will generate a different slideshow images).
      The Setup: GUI with a ListView Control and a simple exit button.
      The Issue: Once double clicked the slide plays however the GUI "locks"/non responsive until the slide is over. Same thing if I click on the "Test" button.
      The Culprit: I believe since it's in the images loop it can't accept any other commands until that loop is over.
      The Wish: I want to be able to use the GUI functions (selecting other items, clicking on button etc.) while the slideshow plays.
      The Code (stripped and simplified as much as I could):
      #include <GuiListView.au3> #include <File.au3> #include <GDIPlus.au3> #include <GUIConstantsEx.au3> #include <WindowsConstants.au3> Opt("GUIOnEventMode", 1) HotKeySet("{Esc}", "_Exit") Global $c=0 Global $ssGDI[3], $ssGraphic[2], $ssImage Global Const $bg_color = "000000" Global Const $ssW = 480, $ssH = 320 Global $aFiles = _FileListToArrayRec("d:\testStage\", "*.jpg;*.png;*.bmp;*.gif;*.JPG;*.PNG;*.BMP;*.GIF", $FLTAR_FILES, $FLTAR_NORECUR ,$FLTAR_SORT ,$FLTAR_FULLPATH ) $guiW = 1200 $guiH = 726 $mainWindow = GUICreate("Slideshow Viewer", $guiW, $guiH, -1, -1, $WS_POPUP) $Button1 = GUICtrlCreateButton("Exit", 0, 0, 50, 50) GUICtrlSetOnEvent($Button1, "_Exit") $Button1 = GUICtrlCreateButton("Test", 60, 0, 50, 50) GUICtrlSetOnEvent($Button1, "Test") Global $ListView = GUICtrlCreateListView("Entry Name|Category", 5, 75, 195, 280) _GUICtrlListView_SetColumnWidth ($ListView, 0, 100) _GUICtrlListView_SetColumnWidth ($ListView, 1, 100) GUICtrlSendMsg($ListView, $LVM_SETEXTENDEDLISTVIEWSTYLE, $LVS_EX_GRIDLINES, $LVS_EX_GRIDLINES) GUICtrlSendMsg($ListView, $LVM_SETEXTENDEDLISTVIEWSTYLE, $LVS_EX_FULLROWSELECT, $LVS_EX_FULLROWSELECT) GUICtrlCreateListViewItem("Name 1|Category 1", $ListView) GUICtrlCreateListViewItem("Name 2|Category 2", $ListView) screenshotWidgetInit($ssW,$ssH, 690, 100) GUISetState(@SW_SHOW, $mainWindow) GUIRegisterMsg($WM_NOTIFY, "WM_Notify_Events") While 1 $nMsg = GUIGetMsg() Switch $nMsg Case $GUI_EVENT_CLOSE _Exit() EndSwitch WEnd Func Test() For $k = 1 To UBound($aFiles) - 1 screenshotWidgetTransition($aFiles[$k]) Next EndFunc Func ListView_Click() ConsoleWrite("Left Click") EndFunc Func ListView_DoubleClick() ConsoleWrite("Double Left Click") Test() EndFunc Func WM_Notify_Events($hWndGUI, $MsgID, $wParam, $lParam) #forceref $hWndGUI, $MsgID, $wParam Local $tagNMHDR, $event, $hwndFrom, $code $tagNMHDR = DllStructCreate("int;int;int", $lParam) If @error Then Return $event = DllStructGetData($tagNMHDR, 3) Select Case $wParam = $ListView Select Case $event = $NM_CLICK ListView_Click () Case $event = $NM_DBLCLK ListView_DoubleClick () EndSelect EndSelect Return $GUI_RUNDEFMSG EndFunc Func screenshotWidgetTransition($image, $delay = 0, $speed = 1, $sleep = 2000) Local $a, $d = $c, $iX, $iY $ssImage = _GDIPlus_ImageLoadFromFile($image) $iX = _GDIPlus_ImageGetWidth($ssImage) $iY = _GDIPlus_ImageGetHeight($ssImage) $FDesktop=$ssH/$ssW $Fact =1 If $iX > $ssW And $FDesktop > ($iY/$iX) Then $Fact=$ssW/$iX ElseIf $iY > $ssH Then $Fact=$ssH/$iY EndIf $H1 = Round(($Fact * $iY),0) $W1 = Round(($Fact * $iX),0) _GDIPlus_GraphicsDrawImageRect($ssGraphic[$d], $ssImage,($ssW - $W1)/2, ($ssH - $H1) / 2,$W1,$H1) WinSetTrans($ssGDI[$d], "", 0) WinSetOnTop($ssGDI[$d], "", 1) For $a = 0 To 254 Step $speed WinSetTrans($ssGDI[$d], "", $a) Sleep($delay) Next WinSetTrans($ssGDI[$d], "", 254) WinSetOnTop($ssGDI[Not ($d)], "", 0) WinSetTrans($ssGDI[Not ($d)], "", 0) _GDIPlus_GraphicsClear($ssGraphic[Not ($d)]) $c = 1 - $d _GDIPlus_ImageDispose ($ssImage) ; very important to realease the pics Sleep($sleep) EndFunc ;==>screenshotWidgetTransition Func screenshotWidgetInit($ssW,$ssH,$ssX,$ssY) $ssGDI[2] = GUICreate("", $ssW, $ssH, $ssX, $ssY, $WS_POPUP, $WS_EX_MDICHILD, $mainWindow) $ssGDI[0] = GUICreate("", $ssW, $ssH, 3, 3, $WS_POPUP, $WS_EX_MDICHILD, $ssGDI[2]) $ssGDI[1] = GUICreate("", $ssW, $ssH, 3, 3, $WS_POPUP, $WS_EX_MDICHILD, $ssGDI[2]) ; GUISetBkColor("0x" & $bg_color, $ssGDI[2]) GUISetState(@SW_SHOW, $ssGDI[2]) GUISetState(@SW_SHOW, $ssGDI[0]) GUISetState(@SW_SHOW, $ssGDI[1]) WinSetTrans($ssGDI[0], "", 0) WinSetTrans($ssGDI[1], "", 0) _GDIPlus_Startup() $ssGraphic[0] = _GDIPlus_GraphicsCreateFromHWND($ssGDI[0]) $ssGraphic[1] = _GDIPlus_GraphicsCreateFromHWND($ssGDI[1]) _GDIPlus_GraphicsClear($ssGraphic[0], "0xFF" & $bg_color) _GDIPlus_GraphicsClear($ssGraphic[1], "0xFF" & $bg_color) EndFunc ;==>screenshotWidgetInit Func _Exit() _GDIPlus_ImageDispose($ssImage) _GDIPlus_GraphicsDispose($ssGraphic[0]) _GDIPlus_GraphicsDispose($ssGraphic[1]) GUIDelete($ssGDI[0]) GUIDelete($ssGDI[1]) GUIDelete($ssGDI[2]) _GDIPlus_Shutdown() Exit EndFunc ;==>_Exit I hope someone can shed light on this; perhaps a different approach is needed?

      Dear Colleagues,
      I have no idea how to refer to style.display in my loop. There is a button like: 
      <input name="ctl00$bodyPlaceholder$btnFecharProcessamento" class="button" id="bodyPlaceholder_btnFecharProcessamento" style="display: none;" onclick="FecharJanelaProcessamento();return false;" type="submit" value="Fechar"> I want it to be clicked as soon as button's style change from style="display: none;" to  style= ="display: inline-block;" 
      This is what I got, but it's not working...
      Func GetButtons() $oButtons = _IEGetObjByName($oForm,"ctl00$bodyPlaceholder$btnFecharProcessamento",-1) $i = 0 While $i <> 1 For $oBtn In $oButtons If _IEFormElementGetValue($oBtn) = "Fechar" And $ = "display: inline-block;" Then $i = 1 _IEAction($oBtn, "focus") _IEAction($oBtn, "click") ExitLoop EndIf Next WEnd EndFunc  
      I will really appreciate if you could help me with these loop!

      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!

      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.
