krishpun Posted April 5, 2011 Share Posted April 5, 2011 I am trying to add elements to an array using _ArrayAdd and _Arraypush, but it is failing. _ArrayDisplay($mismatcharray, "StringExplode") is not displaying anything. Please help. $missmatchdata=$sourcecolumns[$scolumn] & "," & $targetcolumns[$tcolumn] msgbox(1,"s",$missmatchdata) _ArrayAdd($mismatcharray, $missmatchdata) _ArrayPush($mismatcharray, $missmatchdata) _ArrayDisplay($mismatcharray, "StringExplode") regards, Krishna Link to comment Share on other sites More sharing options...
Moderators Melba23 Posted April 5, 2011 Moderators Share Posted April 5, 2011 krishpun,You cannot use _Array* functions on a non-existent array - you must have declared the array beforehand. I am also bemused as to why you use both _ArrayAdd and _ArrayPush. What exactly do you want in your array? This is my best guess as to what you need:#include <Array.au3> ; Declare the array at the beginning of the script Global $mismatcharray[1] ; Now in the script itself $missmatchdata = "Source" & "," & "Target" MsgBox(1, "s", $missmatchdata) _ArrayPush($mismatcharray, $missmatchdata) _ArrayDisplay($mismatcharray, "StringExplode")If I have misunderstood please come back with a better explanation of what the final array should look like.

water Posted April 5, 2011 Share Posted April 5, 2011 Do some errorchecking and insert a ConsoleWrite after each statement: $missmatchdata=$sourcecolumns[$scolumn] & "," & $targetcolumns[$tcolumn] msgbox(1,"s",$missmatchdata) $R = _ArrayAdd($mismatcharray, $missmatchdata) ConsoleWrite("Result: " & $R & ", @error: " & @error & ", @exgtended: " & @extended & @CRLF) $R = _ArrayPush($mismatcharray, $missmatchdata) ConsoleWrite("Result: " & $R & ", @error: " & @error & ", @exgtended: " & @extended & @CRLF) $R = _ArrayDisplay($mismatcharray, "StringExplode") ConsoleWrite("Result: " & $R & ", @error: " & @error & ", @exgtended: " & @extended & @CRLF) My UDFs and Tutorials: Spoiler UDFs:Active Directory (NEW 2022-02-19 - Version 1.6.1.0) - Download - General Help & Support - Example Scripts - WikiExcelChart (2017-07-21 - Version 0.4.0.1) - Download - General Help & Support - Example ScriptsOutlookEX (2021-11-16 - Version 1.7.0.0) - Download - General Help & Support - Example Scripts - WikiOutlookEX_GUI (2021-04-13 - Version 1.4.0.0) - DownloadOutlook Tools (2019-07-22 - Version 0.6.0.0) - Download - General Help & Support - WikiPowerPoint (2021-08-31 - Version 1.5.0.0) - Download - General Help & Support - Example Scripts - WikiTask Scheduler (NEW 2022-07-28 - Version 1.6.0.1) - Download - General Help & Support - Wiki Standard UDFs:Excel - Example Scripts - WikiWord - Wiki Tutorials:ADO - WikiWebDriver - Wiki Link to comment Share on other sites More sharing options...
krishpun Posted April 6, 2011 Author Share Posted April 6, 2011 Thanks, I had declared array as $mismatcharray instaed of "Global $mismatcharray[1000]" Now it is working. But, this poses a limitation on the size of the array, as we will not know how many values we may have to store in the array.This gets decided dynamically. So, is there a way to store data in the dynamic array? regards, Krishna Link to comment Share on other sites More sharing options...
water Posted April 6, 2011 Share Posted April 6, 2011 _ArrayAdd as you use it increases the size of the array (see the example in the help file). So you could define your array as "Global $mismatcharray[1]". Disadvantage: Record 0 will be empty. Performance might be bad because _ArrayAdd does a ReDim for every record you add. If performance is an issue I would suggest to replace _ArrayAdd and ReDim the array in steps of e.g. 1000 records or define the array with the maximum of records and ReDim (shrink) the array at the end of your script.

Mat Posted April 6, 2011 Share Posted April 6, 2011 Here are a couple of interesting systems I've used in various forms in the past. Each one I used because it suited a particular appplication:Keep a counter in the first element and rewrite _ArrayAdd to increment the counter and add the item at that position. _ArrayAdd only increases the size of the array when it needs to, and possibly increases it in multiples 10 or more. I used it when I had an array that was always being made bigger and smaller.Increase the array by lots every time you need to, one of the things Melba usually recommends is to double the size each time.Are they all strings? How about just &ing them together with a seperator and then using StringSplit? AutoIt Project Listing Link to comment Share on other sites More sharing options...
