replace a particular text in a file - (Moved)

Recommended Posts

Hi, I have the following line in a text file 'input.txt'. I know the line number - say '6'. I wish to replace the text 'WWW' in the below line with a random number (I can generate that with random()).

WERIS  WWWJP   3.83  8.330  1.000                1097.RAXX 

The WWW is a 3 digit integer (could be any number between 0 to 999), I can use stringtrimleft and get the numerical value of WWW in this file

so, basically, I know the string to replace (ie; WWW stored in a variable), I know the line number to work on and the file location/name and the replacement variable (through random()). My requirement is to fill that 3 spaces with my random number (which Is a integer between 1 and 999)

please put ur suggestions

Something like:

#include <String.au3>

$s_oldstring = "WERIS  WWWJP   3.83  8.330  1.000                1097.RAXX"

ConsoleWrite($s_oldstring & @CRLF)

$s_newstring = StringReplace($s_oldstring, 8, _stringPad(random(0, 999, 1), '0', 3, 0))
ConsoleWrite($s_newstring & @CRLF)
