Hello,
I am currently writing a program that parses a massive table from a website, and need a way to add a progress bar while parsing.
I am currently using the function _IETableWriteToArray($oObj, True) to parse the array. I need the progress bar to update as the table is parsed, not just at the end of the parsing.
Any help at all would be very much appreciated!
*EDIT --> The array I am left with after parsing is $array[0-50000][16]

My program has to first search for names in Column D that do not match up with column C. I got that search to work using arrays. It was slow and I could not figure out how to delete them so I just manually put coded the names that do not belong. I found their cell location but I do not know how to store that location and delete it.
This is what I have so far.
Local $NameToDelete1[6] = _Excel_RangeFind($OpenWorkbook, "Smith, Bill") _ArrayDisplay($NameToDelete1, "Excel UDF: _Excel_RangeFind Example 1", "", 0, "|", "Sheet|Name|Cell|Value|Formula|Comment") _Excel_RangeDelete($OpenWorkbook.ActiveSheet, $NameToDelete1[2], $xlShiftUp)
Please help, I wanted to have this program done yesterday but I did not see this problem until yesterday.

So Im trying to make a simple 2d game and make some sort of collision detection so why not to make a 2 dimensional array but i have no clue how to write it in multiple lines
Global $map[5,5] = [0,0,0,0,0 _ [0,0,0,0,0 _ [0,0,0,0,0 _ [0,0,0,0,0 _ [0,0,0,0,0] something like this but it doesn't work

#include "..\Include\Array.au3" #include "..\Include\File.au3" #include "..\Include\AutoItConstants.au3" Local $aRetArray Local $sFilePath = "n.csv" _FileReadToArray($sFilePath, $aRetArray, ",") ; _FileReadToArray($sFilePath, $aRetArray, $FRTA_COUNT, ",") _ArrayDisplay($aRetArray, "Original", Default, 8) The above code shows two versions of _FileReadToArray and both don't work as expected.
The first one doesn't use the comma as a delimiter. (so I get a single column array) I tried adding "Default" between $aRetArray and "," then it told me it had an incorrect number of parameters.
I looked again at the documentation:
#include <File.au3> _FileReadToArray ( $sFilePath, ByRef $vReturn [, $iFlags = $FRTA_COUNT [, $sDelimiter = ""]] )
And I with or without the flags params I should be getting a 2D array due to my file being a csv.
I then tried a regular flag, $FRTA_COUNT, and it tells me that I'm using a variable $FRTA_COUNT while it's not declared. Tried putting in 1 instead and it told me again, incorrect number of params.

Hi,
Recently I have had the need to do a sort and then do a second sort while the item of the first sort stays the same ( double sorting , first on column x then while column x is the same sort column y).
I did not put much efffort into error checking but so far I did not need it.
For my applications so far it works perfectly however if someone is willing I want to test this extensivly.
If anyone has big lists of random stuff to sort could you try this out please?
