I'm trying to make a program that can look at a folder directory, find all the CSV files, and then add the data from CSV's to an array.
The problem I seem to be running into is on the 2nd iteration (2nd file) when the script will not create an array. Could someone please help? Thanks in advance
#include <Array.au3> #include <File.au3> #include <MsgBoxConstants.au3> #include <Excel.au3> #include <MsgBoxConstants.au3> Global $MasterArray RefineData() Func RefineData() Local $i, $filenum, $file, $csvArray, $sFilePath = @ScriptDir $fileList = _FileListToArrayRec($sFilePath, "*.csv", 1) ;Create and array of all .csv files within folder ;=====Loop through the .csv files within the folder====== For $filenum = 1 To UBound($fileList) - 1 Step 1 $file = $fileList[$filenum] $sFilePath = $sFilePath & "\" & $file ;=====Create array based on csv file===== _FileReadToArray($sFilePath, $csvArray, $FRTA_NOCOUNT, ",") _ArrayDisplay($csvArray,"File: " & $filenum) If $filenum = 1 Then $MasterArray = $csvArray _ArrayDisplay($MasterArray, "Master") Else $MasterArray = _ArrayColInsert($MasterArray, UBound($MasterArray)) ;want column added at end For $i = 0 To UBound($MasterArray)-1 Step 1 $MasterArray[$i][UBound($MasterArray) - 1] = $csvArray[$i] Next _ArrayDisplay($MasterArray, "Master") EndIf Next EndFunc ;==>RefineData
Hello, I wonder if there is a better way than this!:
#include <Array.au3> Local $aArray $aArray = 1 $aArray = 2 $aArray = 3 ;$aArray = [1, 2, 3] _ArrayDisplay($aArray) IIRC line no. 9 should work, but its not
Thanks in Advance, TD
Hi everyone. New guy here. I'm still learning this awesome language and I'm unable to figure this one out from google searches. Heres my problem:
I'm working on a small application to help users in my environment connect to wireless projectors. To keep this easily updated with new projectors I'm reading the room names and IP addresses from a csv file and putting them into a 2D array. (MeetingRoom1,xxx.xxx.xxx.xxx)
So far I'm able to read the 0 column and display the room names in a combo box. Where I am stuck is how to take the user's room selection from the gui and associate it with an IP address in the array. After that point I've got things prepared to pass the address to the connection application.
Any help you all could provide would be greatly appreciated.
This script is fairly straightforward. If you ever worked with large files before then this may be of help. By large I mean files of 2 MB or so. Granted this doesn't sound so big but going through the file and parsing it to a 2D array all at once took an astronomical amount of time so I wrote my own function to handle this. I discovered that chunking a large array can boost the performance of iterating through the elements and theoretically this should maintain the performance no matter how large the array size is. I know there is room for improvement so please feel free to contribute!
Note: I wasn't able to fully test this on larger files such as 200 MB in size due to AutoIt complaining about an error allocating memory while executing _FileReadToArray(). Any help is appreciated.
Chunking (Performance will never degrade over time; I.E. Capable of parsing 200 lines or 20,000 and no performance hit will occur) Automatically re-sizes to dynamic columns Preserves Columns while parsing FAST!!!!!! (I can parse a file that contains 24,000 lines with variable columns up to 8 columns and it will finish under a second.) Script:
Local $aExport ;Initialize array _FileReadToArray("LARGE TEXT.txt", $aExport) ;Returns 1D array of file Local $aSheet = _ArrayTo2DArray($aExport) ;Converts it to 2D Example Text File:
This script was inspired by >this post.
*Updated attachment: Minor bug fixes*
*UPDATE June 6, 2013: I apologize! I just realized I made a complete mess of the algorithm. I'm working on a fix now.*
*UPDATE June 6, 2013: Bug fixed! It's attached in the post now.
NOTICE: The most current update contains script-breaking changes! The function now works exactly like _ArrayConcatenate. It does not return a value, but sets the parent array as the concatenated array.
I know there's examples of this, but I thought I share this one with you. It's fully commented to aid those learning the language. Supports vertical and horizontal merging. There's minimal explicit variables by design. Not very elegant, but it works.
One advantage this method has is zero dependencies. The dependencies in the download are for the example.
EDIT: Updated script to UDF standards.
EDIT2: Converted to ByRef and Const ByRef parameters (script breaking change!)
Examples in next post. Script above contains examples.
