Calculating the % of a number for a progress bar

[Draygoes]

Ok, this is for future ref.

I will use building a file shredder as an example.

#include<File.au3>

$lines = _FileCountLines( "C:\users\ect")
$currentline = 0

For $currentline = 1 To $lines Step 1
    _FileWriteToLine( "c:\users\ect", "0000000000000000000000", 1)
Next

Exit

If I wanted to add a progress bar to the process, I would need to be able to calculate what line it is out of 100.

This would be easy if the file was exactly 100 lines long, but I hardly think you would ever find a file that is exactly 100 lines.

What equasion might I use to calculate the % complete, and put that in a verable that the progress bar can use?

Thanks all.

Sorry if I have not explained this well enough.

something like :

$currentline/$lines *100

Yes. As saying a Jos

Example:

#include <File.au3>

;$lines = _FileCountLines( "C:\users\ect")
$lines = 78
ProgressOn("Please wait..", "Writing strings", "", -1, -1, 16)

For $i = 1 To $lines
    ;_FileWriteToLine( "c:\users\ect", "0000000000000000000000", 1)
    $percent = Round($i / $lines * 100)
    ProgressSet($percent, $percent & "% done")
    Sleep(100)
Next

ProgressSet(100, "Done")
Sleep(1000)
ProgressOff()

Exit

Thanks guys. This is exactly what I was looking for.
