LOF (Length Of File)

[HimanshuG]

I am new to AutoIt and would like to know if there is any function which can return the number of lines in a file. I intend to go through a file and do something for each line of code as this of course requires a loop I want to make sure that the program only goes through the file till the end. If there is a way to find out if the file has ended it will also do.

Look in the help file for _FileCountLines

Well, technically _FileCountLines loops through the whole file, if you intend to use the file late on, you could use _FileReadToArray(), then you'll have both: The number of read lines in array element 0, and the contents of the file from array element 1 onward.

If you don't want to have all lines in memory, you'll have to use a loop that stops when no more lines are available:

$hFile = FileOpen("myfile.txt")
$linecount = 0
$line = FileReadLine($hFile)
while not @error
   $linecount += 1
   ... do something with $line
   $line = FileReadLine($hFile)
wend
FileClose($hFile)
