How to delete rows in array

[nbala75]

Iam scratching my head to write something like...

I get a csv file with first col like this. Both these figures are present in the first col itself. The first being time and the second one is a number.

14:17:56 4407.85

14:16:56 4399.05

14:15:58 4395.90

14:14:56 4396.15

14:13:58 4392.20

14:12:58 4400.70

14:33:58 4433.20

14:32:58 4427.50

14:31:56 4427.35

14:30:58 4425.20

14:29:56 4425.60

14:28:59 4426.75

14:27:57 4428.00

If the minute field of the above excel row equals/exceeds every fifteenth minute then those needs to be deleted from the array (not from excel). I may get multiple rows for each minute with diff timestamps.

Say

Delete if min field equals 15 or 16 or 17 till i get 29th min rows.

Once 29th minute fields are there, then delete rows containing minute field equals/exceeds 30 31 etc from the array

once 44th minute fields are there, then delete rows containing minute field equals/exceeds 45 46 etc from the array

once 59th minute fields are there, then delete rows containing minute field equals/exceeds 00 01 etc from the array

Thanx for the good souls

Check out the arraydelete() function:

#include <Array.au3>

Local $avArray[10]

$avArray[0] = "JPM"
$avArray[1] = "Holger"
$avArray[2] = "Jon"
$avArray[3] = "Larry"
$avArray[4] = "Jeremy"
$avArray[5] = "Valik"
$avArray[6] = "Cyberslug"
$avArray[7] = "Nutster"
$avArray[8] = "JdeB"
$avArray[9] = "Tylo"

_ArrayDisplay($avArray, "$avArray BEFORE _ArrayDelete()")
_ArrayDelete($avArray, 8)
_ArrayDisplay($avArray, "$avArray AFTER _ArrayDelete()")

Yeah..thanx

At first it looked complex...needing to use loops etc...but when u wrote the above msg, i had a look again and alas! it was just simple....at times, mind needs some rest to look at things in proper perspective...i just cudnt get this easily earlier...sorry guys

nbala75,

See doc for _arraydelete and watch whatever loop control var you are using...you may find modulus arithmetic handy for determining intervals...

If my text file has 10 lines of text and i want to remove range from 5-9. How do i do it using this example ?

[BrewManNH]

Read the help file for _ArrayDelete, the latest version adds the ability to delete a range of rows or just a single one.

I did and i wa confused as to how it works.

I missed the part that it modifies an array instead of returning one. Thats where all my missunderstanding ended.

A general piece of advice: When deleting rows (or sets of rows) several times, it's normally easier to start at the end of the array and work your way to the beginning. This avoids having to adjust index numbers to compensate for rows which have already been deleted.
